Bios Mods -The Best BIOS Update and Modification Source

Hello, i have a little problem with this motherboard, pcs with 8xxx/9xxx nvidia series have ramdom crashes, they released a BIOS update which fix this (rev. 2001), but when you update there is a serious performance lose (around 40%, and im not the only who suffers this) (which happens in rev. 1802/1903), could some1 who knows how to mod bios, do a mix of this 1706 BIOS and 2001 BIOS?

What i mean its, take 1706 BIOS, and add what 2001 BIOS added (which fixes nvidia series 8xxx/9xxx) but without adding what 1903 and 1802 bios added (more cpus supported and some weird change which makes performance lose...)

Or take 2001 BIOS and delete what 1903/1802 bios added :/

Thanks ahead,

Secondary problem, if you can unlock pci lock function (doubt it has it), do it, but its not neccesary.

wow this is complicated stuff. As far as im aware i would have to know exactly what they changed to "Fix Nvidia cards" , perhaps they just updated the video bios? in which case thats easy

Il take a look and see what i can do

Hi,

my first post here. I also have the same problem with this motherboard, and want to add some more info.

I have this motherboard ASUS M2V (Via K8T890) since 2007 and am also having this performance issue with the last two bios (ver. 2001 and 2101). I needed to upgrade to the newer bios ver. 2001 because my old ATI X1900 card broke in October 2010 and could buy an old Geforce 8800GTS from a friend for a small price. I was using bios ver. 1802, the last bios which doesn't hamper the performance according my own experience, but this old bios caused instability (random system freezes/crashes) with the Geforce 8800GTS. Despite that I was able to do a 3DMark 2k6 test which gave me a score of 7636.

To fix the stability issues I needed to upgrade the bios upgrade to ver. 2001, after that I was having low performance issues with the 8800GTS; after the bios update (while more stable now) I get a 3DMark 2k6 score of 6311 (same driver, same bios settings). While the 3Dmark score is decreased with just 20%, some games are not playable at all, e.g. COD4: Modern Warfare is unplayable with the new bios (constant stutter) no matter what settings/resolutions I used, while before with the X1900 I could play COD4 without any issues (with bios ver. 1802). It feels like ASUS did something to the pci-e.

Asrock also has two am2 socket motherboards with the K8T890 chipset (ALiveSATA2-GLAN & and AM2V890-VSTA) which do not seem to have the stability issues and the ami bios on these boards also have a pci-lock. So perhaps it's possible to add the pci-lock in M2V's bios?

Since Asus' site is quite slow, here are the bios files:
