Huananzhi X99-F8D - Dual Socket LGA 2011-3 DDR4 motherboard

After publishing my detailed review of the motherboard, I have figured out a few more important facts:

  • Even though the BIOS on Huananzhi X99-F8D is blocked for FPT, it's possible to flash the BIOS with AfuDos. Compatible AfuDos version as well as the original BIOS can be downloaded from the official Huananzhi website.
  • There is an alternative USB 3.0 driver, which resolves issues with the ports.

The USB 3.0 driver and X99-F8D BIOS with compatible AfuDos can be downloaded from my OneDrive.

Hi Konstantin. First thanks for your review videos, they are really informative. Secondly: Which M-ATX sized x99 board would you recommend? DDR3 support would be a plus as I have those laying around. Greets & Thanks, eetu

Miyconst on 31 July 2020 14:42 says

eetu, thank you for your support! For an mATX build I can recommend Huananzhi X99-8M, Machinist X99Z, JingSha X99 D4, unfortunately, all of these boards support DDR4 only, but Huananzhi X99-8M is also available in X99-8MD3 variant, which supports DDR3. Beware, X99-8MD3 I have not tested yet, thus I can't guarantee that it's as good as X99-8M.

My reviews for these boards you can find here:

Hey man Do you know if the EFI driver for Turbo boost work on unRaid OS? I'm planning on building unRaid server for running my media server and VM WIN10 for some CAD work, video editing/rendering, secendary streaming PC and/or light gaming PC :). I'm planning on using 2xE5-2680V3 with that motherboard and GTX 1660 Ti/Super. If you have any other part/build suggestion for this type of build, i'd love to hear it.

Keep up the good work on the videos! Huge thanks from a Land of Sauna's :D!

Miyconst on 06 August 2020 11:41 says

Sami, I don't know much about the unRaid OS, sorry. You can always try, but it's probably not going to work.

Stiggity on 08 August 2020 17:49 says

I'm thoroughly enjoying ALL of your content. I purchased a Chinese x99 dual socket ddr4 board, backed up my original BIOS, anhd the turbo unlock wont work passed 2.5Ghz on an E5-2683v3. I went to restore my original BIOS, and try a di9fferent approach, but accidentally deleted the factory bios ROM :( My X99 board only shipped in a box that says "X99" it has 2x PCI-E x16 slots, 2x m.2 NVME. Looks similar to the Huananzhi X99-F8D, but with an extra m.2 and 1 less PCI-E x16 slot. Which stock/factory BIOS that you host, would you recommend, to get the board back to factory state? Thanks a million! :)

Miyconst on 08 August 2020 20:39 says

Stiggity, I have not yet tested this board, but you can find the original BIOS here.

Stiggity on 09 August 2020 00:15 says

Miyconst, I re-flashed my BIOS with the "unlock" portion of it's name, and I couldn't get Windows to load off of my NVMe ssd!!! and I couldn't read the language, so I took a chance with flashing the ***-unlock.rom The board boot up right away, but would NOT allow windows the boot, so I reinstalled, and am in the process of getting things set back up. Are both of those .rom's stock?? Right now 2.50GHz is all I can Turbo too. Possibly your fluent in the linked language? Or should I go through the Turbo Unlock procedure since I have a stock .rom??

Stiggity on 10 August 2020 07:14 says

Miyconst, I've tried everything, and I can't get this board to "Turbo" above 2500MHz? The link you shared, has 2 BIOS ROMs, is the first a Factory/Stock rom? and the second, a already unlocked BIOS??? any sort of help is appreciated. If indeed the first download is the factory ROM, i will apply that, and start over. Thanks! : )

Miyconst on 10 August 2020 11:43 says

Stiggity, you can use Google Translate to check the files' description, but yes, the first file on the page is the original BIOS for this motherboard. Still, anything you do is under your personal responsibility. I have not tested this BIOS and have not tested this board.

Sami on 11 August 2020 14:23 says

Hey Miyconst, Sami here, again.

To my understanding unRaidOs is Linux based OS and if i'm understanding your video correctly, your Ubuntu test show max clock speed as 3.3gHz. If Ubuntu is showing correctly, then it's allowing Turbo Boost on those two CPU's. So, my question is, did you do the BIOS flash with EFI driver before or after the Ubuntu test? Sorry to bother you, again :) Keep up the good work on videos!

Hung Nguyen on 16 August 2020 16:01 says

Hey, Miyconst, just want to say thank you for your blogs/content. I enjoy it very much (and I may have questions, if I pull the trigger to buy a Kllisre mobo later :D). Love from Vietnam, you Russian guys rock!!!

Laurent on 16 August 2020 17:42 says

Hello Konstantin,

Hello from France and a great thanks for your job, youtube channel, blog... it's really a good job and very important for the community ! ;) So thanks again !

I want to make a little station for Photoshop/3d/pao and gaming, and i've seen this Huananzhi X99-F8D who seem very good, but i'm a beginner and i've a few questions.

is HUANANZHI a serious chinese brand about quality and client services ?

I'd found on aliexpress a lot of kit with this motherboard and CPU/Memory like this :

and of course a lot of sellers of memory like this :,searchweb201602_,searchweb201603_

What do you think about the better choice performance/price for cpu in my case ? for example : are the E5-2678v3 or E5-2680v3 a goood choice for my job/game (actually i've a single X5690 clocker at 4.3) ? what about the unlocking turbo (all the E5 are the same and with your method there are no problem) ? May be you have better choices on the E5 ?

For memory : i'm not sure, it's of course ddr4 ecc but the speed depend of the cpu, so is 2400 a good choice useable for all cpu (even at lower frequencies) or i must absolutly choose the good frequencie for the good cpu ? is better for me to choose (quality/fiability) samsung or other brand ?

Can i start with only two ddr4 ecc of 32go (with a big possibility of futur evolution) or it's better for the maximum memory bandwith that i start with 4 ddr4 (4x16 go for example) ?

My questions are very basics but there are so possibilities that it's a lot for a beginner ! ;)

Thanks again for all your job ! ;)

Miyconst on 16 August 2020 18:32 says

Hung Nguyen, thank you for your support, but there is one thing you need to know: I am Ukrainian, not Russian. 🙂

Miyconst on 16 August 2020 18:59 says

Laurent, for Photoshop you need as high CPU clock frequency as possible and as low RAM latency as possible. Thus, dual socket configuration is a big no-go in your case.

For you, I would suggest a Xeon E5-1650 V3 or E5-1660 V3 on a JingSha X99 D8 motherboard with some tuned DDR4 ECC REG memory modules, for example these from Samsung.

You can also buy a complete set of Xeon E5-1650 V3 / JingSha X99 D8 / 4 * 8 GB DDR4-2400 ECC REG.

P.S. Do not by engineering samples (ES) CPUs, these have locked multiplier and you can't overclock them.

Laurent on 16 August 2020 21:01 says

Thanks Konstantin for your ultra fast return ! ;)

so if understand and to be sure : you think a mono cpu is better for me because of the max clocking ?

It's because we can't overclock cpu on a dual x99 but it's possible on the mono cpu JINGSHA X99 D8 with the original bios ?

So if i put 2 E5-1650V3 or 1660 on the dual x99 i can't have the best because of the clocking ? idem with the ddr4 timings ?

The différence between dual x99 and mono x99 is not very clear for me...

The JINGSHA X99 D8 seems to be very good, it looks like an asus ! ;o

OK for the ES samples ! ;)

Of course all people try to have the best with a good budget and i'm looking at the good ratio performance/price of the last amd ryzen...

So me ! ;)

stiggity on 17 August 2020 02:48 says

Miyconst: I'm sorry too sound like such a newb. Is there any way you could link me to a youtube tutorial on unlocking the turbo, once and for good. I have the dual socket klissre x99. So far, it's a great board, and duration in shipment was <2weeks. I'm in USA, needless too say, i was impressed. Really digging your videos and content. ** VERY EDUCATIONAL! ** keep at it. I successfully unlocked turbo on my Gigabyte GA X99 Gaming G1, and it was a breeze... i tried the exact same method, But chose (Dual CPU) and it was a big no-go. Any help would be greatly appreciated.

Hung Nguyen on 17 August 2020 08:32 says

[b]stiggity[/b], oops, I'm so so sorry, I can't tell the difference in the languages. Being a Vietnamese, I can feel that, as we're kept being called Chinese (and we hate Chinese).

Miyconst on 17 August 2020 10:43 says

Laurent, for dual socket CPU you need a pair of identical Xeon E5-26XX/E5-46XX. Xeon E5-16XX are only working in a single CPU configuration. You can install such CPU on a dual socket motherboard, but only one CPU will be active.

For your work you need as higher clock as possible, and as low memory latency as possible. Xeon E5-1650 V3 and E5-1660 V3 are unique CPUs in the V3 line-up because they have unlocked multiplier and it's possible to overclock them. With these CPUs, it's also possible to overclock RAM to DDR4-2400 on the Chinese motherboards.

Miyconst on 17 August 2020 10:45 says

stiggity, I already have two video and text tutorials on how to unlock turbo boost frequency on all cores. Still, I have to disappoint you, so far, the "Once and for every" method does not work on dual socket motherboards. So far, I don't know a single successful case, only manual EFI driver installation works well.

Laurent on 17 August 2020 13:03 says

Thanks, Now it's really clear ! ;) the E5 16v3 are mono cpu, unlocked and possibly overclocked (not qs or es version), you talk only about 1650 and 1660 because of the price but is the 1680 (and all the 16v2) unlocked/overclocked ? or only 1650/1660

Because i've actually gskill ddr3 I'd seen in your reviews the good HUANANZHI X99 TF (ddr3 first and after testing i can buy ddr4) but it seems that overclocking is not possible !

really ? no modded bios or other bios update from the brand ? what a shame for a good motherboard like this ! ;o

so in mono cpu with overclocking the only really good motherboard is Huananzhi X99-F8D with ddr4 ? and better cpu choice E5 1650/1660V3...

i've seen your very good review on the memory on the HUANANZHI X99 TF, in certain configuration it's very disapointing !!!

Laurent on 17 August 2020 13:22 says

Edit : fault about (and all 16v2) it's : all 16xxV3 off course ! ;) sorry for the bold typo it seems that certain character like the asterisque change the style ;o

Miyconst on 18 August 2020 08:50 says

Laurent, here are some more answers:

  • DDR3 memory is only supported by a handful of Xeon E5 V3 CPUs, unfortunately, all of these CPUs are locked and not possible to overclock. The most popular one is Xeon E5-2678 V3.
  • It's not possible to add DDR3 support via a BIOS mod, because a physical DDR3 memory controller is needed to work with DDR3, while most of the Xeon E5 V3 CPUs have only DDR4 memory controller.
  • As far as I know, Xeon E5-1680 V3 also has unlocked multiplier and it's possible to overclock it. The E5-1620 V3 & E5-1630 V3 are unfortunately locked, and it's not possible to overclock them. The rest of the E5-16XX V3 lineup is very rare and there is no definite information on whether they are locked or unlocked.
  • You should not buy a dual socket motherboard for a single CPU usage.
Sam on 18 August 2020 11:56 says

Hello, quick question. Is it worth upgrading from E5 2620 v3 to E5 2678 v3? I mainly use my system for gaming. Thanks

Miyconst on 18 August 2020 12:16 says

Sam, it depends on the GPU. If you have something RTX 2070, then it makes sense to upgrade.

John on 18 August 2020 17:39 says

Big fan of yours here, I ordered Jingsha X99- D8 which should be here any day now, the seller claims he's already flashed the bios thto unlock turbo mode.My question is, how do I check when I get the motherboard?

Miyconst on 19 August 2020 09:15 says

Hi John, it's very easy to check if you are using a Xeon E5 V3 CPU. Just run a short CPU-Z test and observe CPU clock frequency in the task manager. If the CPU boosts up to it's maximum boost value on all cores - you have Turbo Boost Unlocked.

You can also create a dump of your BIOS and check if the 06F2 CPU microcode is present.

Stiggity on 21 August 2020 07:50 says

Miyconst: After removing the microcode, and flashing the BIOS, i then boot to my FreeDOS USB drive created by Rufus. I do Not have "fs1:" simply "fs0:", which is my USB drive. I also have blk1: , blk4: , etc...I also noticed in BIOS I don't see "Windows Boot Manager" in my boot options. What am I doing wrong? Any sort of help will be greatly appreciated!

Miyconst on 21 August 2020 08:18 says

Stiggity, you have non UEFI Windows installation, which is not supported with manual EFI driver installation.

stiggity on 22 August 2020 01:24 says

Miyconst, what do i have to do to have an authentic UEFI windows installation? I installed windows from a USB drive that it comes on? Is there a BIOS setting, or won't it ever work?

Stiggity on 22 August 2020 02:34 says

Miyconst: After a quick search, my Non-UEFI windows 10 installation was converted to a UEFI standard. Went into BIOS and set some things differently. Finally, un-locked my Turbo Boost. Dual 2683's.. I'm seeing 2.80-2.98Ghz. Much different than previously only being able to MAX-OUT @ 2.45Ghz... I appreciate your talent, tutorials and content. If/When you get one of these Dual Socket boards, you will be impressed.

Dave on 08 September 2020 04:28 says

I was looking to know if anyone has a English manual for the Huananzhi X99-F8D. I did not find any on the website. I am looking for the jumper settings and dip switch. Also for the memory which slots need to be populated together (i have 4 sticks of 16GB hynix Pc4-2133) and 2 x E5-2640 V3. Finally if I use only one CPU is it needed to use a specific slot cpu first? Many thanks to all for help.

Miyconst on 09 September 2020 10:40 says

Dave, I really doubt that you will be able to find any useful English manual for Huananzhi motherboards. Here is the official support page, there you can find some downloads, but don't expect an English manual - 华南X99-F8D双路主板.

John on 11 September 2020 02:25 says

Thanks for your advice earlier. My Jingsha X99-D8 arrived and everything is working except one of the Ram's I ordered. Bios RC version is (ram timings is missing in the memory configuration).So I can't underclock the ram I ordered which is 2666mhz. My question is, can I reflash and use your bios instead?Or I should just give up and buy 2400mhz ram rather?I've attached images


Ivan on 18 September 2020 09:35 says

доброго времени суток, спасибо за обзор - очень информативно. Подскажи пожалуйста - есть ли информация о том поддерживает ли данная плата технологию PCI-e bifurcation (разветвление PCI-e x16 на несколько x4 например для мультипликации скорости i/o)

Miyconst on 18 September 2020 09:39 says

Ivan, вітаю. Налаштування PCI-E Bifurcation в BIOS є, але чи працюють вони чи ні – ще не перевірив, бо не було чим перевіряти. Зараз отримав ASUS Hyper M.2 X16 Card V2, в якості пожертвування до каналу, тому планую перевірити коли буде нагода.

Ivan on 18 September 2020 09:47 says

Miyconst, спасибо за информацию, буду ждать результатов)

Ahmed Tantawy on 20 September 2020 05:36 says

I really appreciate all of your hard work, I have to say that you impressed me with all of the detailed testing your doing on all of these products! I watched this video about the X99F8D and bought the motherboard and 2X(E5 2680) from the official website Huananzhi from Aliexpress website, the motherboard and processors are working just fine but I'm getting some beeps at every start before the bios check single beep that I know is normal, and the weird thing is that these beeps are changing from 3 beeps at first and then they became 2 beeps, and finally it's now making a two beeps and then a one second pause and then two more beeps and then the one bios check beep. My questions are: Is that normal with this motherboard or there is something wrong? I contacted the seller and they are saying that it's normal but I doubt it! Would you please replay to this message because I'm so frustrated about that. Thank you in advance!

Miyconst on 20 September 2020 11:20 says

Ahmed Tantawy, as far as I remember, the motherboard has a few beeps on start, but in my case it was consistent with the beeps, every start the same number of beeps. Thus, you have two options:

  • Try to investigate what is going on by removing all unnecessarily components and check how the motherboard behaves.
  • Leave it as is, since the motherboard works well after the booting process.
Ahmed Tantawy on 21 September 2020 18:56 says

Miyconst, Thank you so much for that fast response. I think I will go with the 2nd option and leave it as is since I tested all of the hardware and it seems like I don't have any issues. I have another question if you don't mind, I'm trying now to turbo boost my dual CPUs and going through your guide, but I'm not being able to read and make a backup copy of the BIOS by FPT (DUMP operation). What other applications would you recommend to use to unlock my BIOS and be able to make a copy of it and change it? Thanks you!

Miyconst on 21 September 2020 19:50 says

Ahmed Tantawy, you can try to use AMI Flasher Utility (AfuWin), it's not as easy to use as FPT, but it can bypass the write locks, which prevents FPT from accessing the BIOS.

Stiggity on 27 September 2020 10:44 says

Miyconst, Well.. i thought i had it in one of my last posts, but now im sure. YAY!! Here's a doozey for ya! Both of my 2683 v3's are water cooled, but under a full load for about 1 minute, CPU:0 Hangs ~ 55C and CPU:1 Hovers 75C this is with all 28 cores maxing at 3000Mhz and both pumps, radiator fans, and case fans throttle up (All moving parts share from the (2) 4pin headers... What kind of temperatures would you consider... Dangerous/Alright/Good? Thanks miyconst!! You are the man...

Miyconst on 27 September 2020 11:57 says

Stiggity, everything under 90C is safe, but I would recommend to keep the temps under 80C.

Ivan on 02 October 2020 06:23 says

Thanks Miyconst! All your information about X99 motherboards are very useful. I wonder what computer case and power supply you suggest for Jingsha Dual X99? The board is even bigger than most other E-ATX and can't seem to find a case for it. And most power supply does not have the second 8-pin EPS connecter for dual CPU?

Also, other than the E5-16xx series CPU can overclock, I heard the E5-2687W (v1/2/3/4? Not sure which) can also overclock. Have you tried that CPU? Or if the ES CPU can overclock like the retail version?


Miyconst on 02 October 2020 10:58 says

Ivan, I am using the following chassis for my dual socket builds: Fractal Design Define XL R2 and Phanteks Enthoo Pro M.

I have not heard anything about the E5-2687W being overclockable, and the ES CPUs do not have a general rule to apply. Some have locked multiplier, others have unlocked.

orange on 09 October 2020 20:05 says

hi miyconst, would like to ask if x99-f8d dual socket can support E5-2620v1? also is support DDR3 ECC ram? thanks in advance.

Miyconst on 10 October 2020 13:04 says

orange, no, it does not.

orange on 10 October 2020 16:59 says

thanks for the time to respond Miyconst, just to clarify... so lower version (v1) do not compatible to x99-f8d right? -thanks

Miyconst on 10 October 2020 19:44 says

orange, no, Xeon E5 V1 & V2 are for LGA 2011 socket, while V3 & V4 are for LGA 2011-3 socket.

orange on 11 October 2020 05:21 says

got it, thanks much for the clarification Miyconst

orange on 12 October 2020 09:32 says

Hi Miyconst, i forgot to ask this.... is Xeon E5-2680v4 (ES/QHVB) compatible with this X99-F8D (LGA 2011-3 socket).. thanks alot in advanced. God Bless!

Miyconst on 12 October 2020 21:10 says

orange, sorry, I can't help with the V4 ES CPUs. I know that some of them are supported and others are not supported, but I can't say much about the Xeon E5-2680 V4 (ES/QHVB) CPUs.

orange on 13 October 2020 11:19 says

oh ok... no worries, Miyconst, i will try to dig up more on the net ;). thanks

Aurellien on 14 October 2020 20:15 says

3 questions,

How do I know what ram is compatible with ZX-DU99D4

Can I unlock turbo boost on a 2 E5-26XX cpus with just 1 8-pin(2x4) connector?

Does this motherboard support SLI or Crossfire

anyways thanks for the amazing, clear, honest and detailed reviews on youtube!

Aurellien on 14 October 2020 20:16 says

Aurellien, 2 E5-26XX cpu's*

Miyconst on 14 October 2020 20:58 says


  1. Try and see if it works or not. The best option would be 8 GB and 16 GB DDR4 ECC REG memory modules.
  2. Yes, you can, but I would strongly recommend to use both 8-pin power connectors.
  3. I have no idea, sorry. Theoretically it shall work, but it's not validated.
Peter on 15 October 2020 03:07 says

Did you ever figure out the beep issue, I have the same problem, and the beep count changes from time to time, seems to work ok.

Miyconst on 15 October 2020 05:02 says

Peter, sorry, but I did not. I have a Huananzhi X99-T8D motherboard, and it also beeps like that.

Ahmed Tantwy on 15 October 2020 07:25 says

Peter, I talked to one of the engineers in the company and tried to understand anything about those beeps and they said that it’s a normal additional check in the motherboard, but they didn’t seem to have a solid answer for changing the beeps. They said I should only worry if the number of beeps is 5 beeps or more. I’m using the X99 F8D motherboard for almost a month now and it’s working perfectly fine with me. I noticed that the number of beeps changes when I plug any device to The front USB ports. I have 8 RAMs and using dual processors, so when I tried to Change the slots and number of RAMs used, and it also changed the number of beeps. So the conclusion is as long as you don’t change any of the internal components or the devices connected to the USB ports, you wouldn’t hear any difference in the number of beeps. And if you changed anything and still have less than 5 beeps that should be fine.

Ahmed Tantawy on 15 October 2020 07:33 says

Miyconst, The AMI Flasher Utility (AfuWin) worked and bypassed the Write locks as you mentioned. Thank you so much!

Stiggity on 21 October 2020 03:00 says

Miyconst, I have yet another question. I've unlocked all core turbo on (2) 2683 v3 cpu using the Klissre dual socket x99 motherboard. Once i execute install.bat and autostart.bat then restart windows everything works as it shud.. but!!! the machine locks up. Not at the same place/time/app, every time. but!! somedays it will run for 2 or 3 days, or 1 day but it WILL lockup. And I mean no blue screen, or memory-dump. But! after pushing the reset button, and I get back into windows, and do not launh install, and autostart.... turbo unlock is not implemented, and the system will Not hang/freeze/lockup. Is there something im missing?? i also noticed in your turbo unlock download package, a set of UPdated cpumicrocodeupdate files. Any help would be great..

Miyconst on 21 October 2020 14:35 says

Stiggity, it is very hard to guess what the problem is. Did you disable CPU C6 state in the BIOS? Also, it sounds strange that you have to install/start the drivers on every system startup, something is wrong there. All my recent tests were conducted without any extra drivers installed on the Windows level. This cpumcupdate thingy is no longer needed, as far as I know.

Fadlan on 21 October 2020 22:40 says

Hello, thanks for your review here. Do you already test PCIe bifurcation? I wanna know too, if this board can bifurcate to 4x4x4x4 all slot. And what is PCIe mode for there 3 slot? Is it 16x,16x,16x?

Miyconst on 22 October 2020 00:15 says

Fadlan, all three PCI-E x16 slots are PCI-E x16 3.0, bifurcation settings are available in the BIOS, but I have not tested it myself.

Juan Alejandro on 22 October 2020 02:24 says

Hi, thank you very much in advance for your attention and for the information shared on your channel. I recently bought the following components: huananzhi x99-f8d, 4x16gb ddr4, 2 xeon 2678v3, power supply "xpg core reactor 850w gold plus", HUANANZHI SSD M.2 NVME SSD, and a video card "xfx rx 580 4gb". at the beginning when it turned on, it showed me the code "A0", after connecting the hard disk it shows me the code AE ​​and later "00". I don't know if this problem has happened to you before, and if you can tell me what is happening. I have already disconnected the disk and the video card. thank you very much.

Miyconst on 22 October 2020 10:49 says

Juan Alejandro, if I understood your correctly, the motherboard does not start any more after you have tried to install an NVMe drive. The post code is 00, is that correct? If yes, then I would suggest to contact the seller. It could have happen that you have had the NVMe/SATA mode jumpers connected the wrong way and once you installed your drive a short circuit has happened and the motherboard fried.

Luis on 26 October 2020 18:32 says

Dave, I used google translate on my phone and it translated the booklet instantly using the phone's camera.

Stiggity on 26 October 2020 19:35 says

Miyconst: I'm currently running (2) 2683 v3 processors. Will I need to re-do the unlock procedure if I upgrade my processors? They will still be 26xx v3, just something with a slightly higher, cache/clock/turbo frequency.. Any words of encouragement would rule!!

Miyconst on 26 October 2020 19:44 says

Stiggity, I assume you have used the manual EFI driver installation method, in this case you would most likely have to reinstall the EFI driver.

Mario on 29 October 2020 23:50 says

Hi, I am looking for a good CPU cooler for this board that can fit in a 4u rack mount case (I have probably 135 to 140 mm of clearing after accounting the mount point, motherboard, cpu socket. Any recommendation that would fit with the 2 CPU and the hight constraint?

Thanks !

Miyconst on 30 October 2020 02:15 says

You can take a look at Noctua NH-L12.
