Hi all,

Just to share my thoughts regarding the new EVGA 780 - SC ACX - 80.10.37.00.0B - 'OC edition v00' flashed on a reference card -

Max fan RPM@100% 3300rpm GPU temp idle ~35*C

Nvidia GTX 780 - 80.10.36.00.01 - 'OC edition v00'

Max fan RPM@100% 4300rpm ; GPU temp idle sub 30*C

Loaded temperatures are exceeding 10-15*C

So higher fan limits, or modded normal .37 SC bios would be highly appreciated.

No problems with stability/overclockability or whatsoever with both of them so far, great BIOSes to be exact with boost removed and idle state Volts/freq reduced also max Votls/limits increased compared to reference ones

@svl7 could you upload another EVGA SC ACX BIOS with over 100% fan? I am using the BIOS on a reference GTX 780 and the fan speed is much lower.

Yes that's exactly what I am struggling and complain about it at the previous page. We'll kindly appreciate more juice to fan pwm, for the reference cards

Thanks svl7

@svl7- As I mentioned on my previews post with very low OC ability, I had a bad flash and I did re-flash my both cards one by one. and i did ran some bench's with great result.

the New SC ACX vbios has maintained great OC ability, cards won't throttling down, It clocks up and down like a normal bios and voltage goes up once the cards needs to push and comes down once the cards don't needs to push. idles at 324MHz @v875 when watch youtube video clocks stay the same

Can you explain in details what you did to get bad flash, what commands or whatever we should avoid, thanks in advance

The first OC bios is more stable than SC ACX (0B) bios, I know the first bios was not for SC ACX GPU it has low GPU clock at stock compared to the SC ACX GPU. This bios can even hit 1201MHz stable it does crash right after with the first bios I could hit 1241MHz stable voltage Memory OC 100MHz and up.

1241Mhz stable...all games ? Sounds like a winner there, how does ACX bios act in terms of fan control ? 1201 crashing, sound like driver problems with you. How does +100 mem translate in terms of real freq ? And last question, do you monitor your voltage, are you sure that you're applying what you set in Voltage section for real ? It seems that you get no benefits at all with overvoltage, compared to your stock bios, witch sounds strange.

I didn't adjust the fans of the ACX as I don't have an ACX cooler and don't know whether it needs adjusting and what needs to be adjusted...

Note that the SCX and non-SCX will have different fan behavior, even with the stock. With which mod did you get 4.5k? I guess with the ACX since that one has a higher fan speed in it.

Hi svl7

I'm on a reference card. With both 36 and 37 SCX stock BIOSes flashed with max fan set to 100%, i'm not able to speed over 3.5k the fan. Didn't still tested your modded BIOS so that's why i'm asking about that, if someone tryed it on nonSCX card and how the fans are acting

With 36 stock 780 bios and your modded Nvidia GTX 780 - 80.10.36.00.01 - 'OC edition v00' the fans are speeding with 100% set up to 4500rpms

Hi svl7

How is fan control for ACX bios.

Is it fixed speed control, someone who tried it on regular card, care to shere his maximum fan RPM with 100% fan. Because with older 36 version my reference card is speeding only up to 3.4k rpm, while with the modded one and reference 36 bios it goes to 4.5k max speed .
