Which DFI NF4 bios for Twinmos AA4T UTT?

[Major]

the 510-2 is going to be hard to beat with UTT, if I were going to try another it would be 704-2 bigtoe mod but I don't think your going to see any change in ram OC.

Major: Thanks
I tried 704-2BT but I gained no more memory MHz. Did you try 510-2 fix or Merlin and Helfire modded bios?

Depending of which ram divider you will use, 9/10 seems to be unworkable passed bios 510-2.
Each time I'm trying to use this divider with later bios than 510, the screen is freezing at the Backup CMOS part after the DMI information and can't boot into windows @2750Mhz (275x10) DDR500 ram with the 9/10 multi but I can with @3000Mhz (300x10) DDR500 with the 5/6 multi.

Also, I moved to 704-2 Bigtoe bios 2 days ago and I'm getting a new BSOD callled Trap_Cause while running @3Ghz. I googled this error and found only 3 webpages about it.... all in german

I will give a try to Xcel and merlin bios. If they are not better, I'm going back on the original 510-2 or fixed bios and will camp it until I'm done with A64 and DFI

Update:

Trap_cause seems to be gone after switching both ram to the YELLOW slots and 3 bios (bigtoe, Merlin, Xcel2updated) where I was getting this error in Everest Writing Test.
