GTX 600 Series Unlocked Voltage Bios' downloads and tools. - Page 218

post #2171 of 7931
hi -

i used a new version of bios to unlock - deleted the first

and i have the older dos version on a bootable usb with my std saved bios for those " oh s**t " moments
post #2172 of 7931
I have tried the recommended modded galaxy bios for the MSI power edition 670. I am having a weird problem where heaven benchmark runs fine if I have my 2 screens duplicated, but heaven fails everytime, even at stock speeds, when I try to switch to extended or even single monitor mode. Any idea what is causing this? I am using the GTX670GF.ROM bios provided by darkadi.

Tried: reflashing, and re-installing drivers twice.

Also forgot to mention this only happens in SLI mode, is there a problem with having to cards with exact same bios?

Hello guys,

I have the Gigabyte 670 windforce OC edition and I wonder if I can use the bios flash tool provided by the GB site. I didnt find in the first page mention that we can use an official tool. Do we have to use the nvflash tool only?

Thanks thumb.gif
post #2174 of 7931
Furthermore.....can anyone have used the KGB tool together with the Gigabyte bios flash tool?

No problem, and you shouldn't have any issues with KGB and the GB tool.

Hi,

I have just unlocked the bios of my MSI GTX 670 PE with KGB and it works like a charm.

The card boost to 1306.5Mhz on any games / bench without overclock.

I was not stable with the stock voltage (1.2120V) but with AB 2.2.3 and +20mV on the core, it's stable smile.gif (+10mV it's not stable)

AB 2.2.4 - 2.3.0 doesn't work at all, not stable even with +100mV ..., anyone know why ?

I have bench 24H on heaven with all settings max out and the core was always at 1306.5Mhz.

Played with Farcry 3 all settings max out and no crash either.

So thank you for the KGB tool smile.gif

This is weird since I have 2 cards that both have erratic clocks with +100mv added with AB2.2.3 on the kgb inlocked bios'. I wonder if the AB voltage is culmulative, causing the voltage to be higher than reported (1.21V)? I may have to try the unlocked bios' again with lower AB voltage. This may also make sense as the modded galaxy bios i tried for the power editions didn't allow both my cards to run 1411mhz through a heaven benchmark, while the unlocked bios did for the 2-3 good runs I would get without downclocks. Any thoughts on this? I have heard a rumor that these cards have a supplementary voltage source, maybe that is where the discrepancy is coming from with different bios'. Have you pused your cards to a highest stable overclock? I know I am very close to my highest when I get the erratic clocks the fastest.

flashed my 670 reference with KGB unlocked 4B BIOS and card is stable at same former vmodded clocks (1300MHz core & 3432mhz mem - being +98/+425 offsets @ 150% PT). passed Heaven3.0 and 3dmark11.
max stock BIOS clocks were 1246MHz core and 3571MHz mem (offsets +149/+564).

all seems to run well except Vantage causing RSOD or plain black screen reboot, but it was like that on former rev.19 vmodded bios too... stock 4B was free of this problem however but the earlier stock revisions were carrying the same problem though. I guess the cause of RSOD/BlackSOD is the power target going over board at some point, not sure why only in Vantage.

anyways, testing it with games now. so far so good, I think smile.gif
