Really enjoyed your videos.
I have the T5810 with E5-2620V3 and wanted to try the turbo boost unlock on my system. Just noticed that there is an A33 version of the bios released a few days ago. Would you be able to patch up the A33 bios with turbo boost unlock?

Thanks a ton!

Wei, thanks for the feedback. You can watch my Turbo Boost Frequency Unlock guide and patch the BIOS yourself, but if it does not work - I can help.

Hi Wei,

I also have a T5810 and have a USB EEPROM reader/writer with bios chip clamp on the way. Hope the clamp is better than what I've had before. I've already installed the updated A33 bios and will have a go at modding it when the kit arrives. I'll let you know how it goes with another post here.

FYI I'm running an E5 1620 V3 with and have been waiting 7 weeks for an E5 2660 V3 from China. They must be swimming it over.

Your work is very much appreciated Miyconst.

Cheers, Troy

Troy, that would be really appreciated.

Miyconst, appreciate your work!

Hi Miyconst, are you aware of a BIOS patch for HP Z440? Got my hands on wholesale price for one which has a 1620v4. Thanks for sharing your work! Terrence

NVM, just read your flashing guide and you already point out that E5 v4 arent supported by that BIOS patch. Maybe in the future there will be one!
