flashing 680 bios.

[Speedy Pete]

Just got my MSI lightning 680. But unfortunately its one of the newer ones with the locked bios.

Ive downloaded nvflash 5.118 but when i go to run in from cmd prompt i get the following message " cannot run or start nvflash.exe because of 64bit something something "

Im following this guide :

To flash the BIOS, download the latest version of nvflash here.
extract the nvflash files to C:\
save the BIOS file to C:\
open elevated cmd window (hit start button, type "cmd", right click cmd icon, run as administrator)
change directory to C:\ (type " cd C:\ " )
OPTIONAL: type " nvflash --protectoff " then hit enter (turns off any error msg that may result from software write protection)
BACKUP ORIGINAL BIOS: Type " nvflash -b backup.rom " and a copy of your bios will be saved to the nvflash directory
type " nvflash -4 -5 -6 680L_UnlockedBIOS.rom "
wait for it to finish
reboot
OPTIONAL: reinstall drivers



Anybody know what im doing wrong?

I flashed the LN2 bios which was 80.04.28.00.3A to 80.04.09.00.F8.

Currently at 1.3ghz core and 6.7ghz mem. no problems so far

+93mv in afterburner. For some reason it wont stick on 100 :/

Finished playing now and have core at 1.34ghz and mem at 6.8ghz.

Just looked at voltage and it aint going over 1.21v ... w..t.f ? lol

 

[Speedy Pete]

well i had it a fair bit higher earlier on but locked up on 3dmark so i assume its stable now.

edit: is gpu-z reading the voltage wrong? A.B 2.2.3 with the 80.04.09.00.F8 successfully installed.

Is this also something that happened with you gregster?

 

[Speedy Pete]

Afterburner doesn't have any voltage readings. Only the slider which shows how much extra ive added.

 

[Speedy Pete]

ahh ok, fail on my part.

Voltage is 1.273ish
