EVGA 780 - SC ACX - 80.10.37.00.0B added to the first post, please report back.

Anything particulary different from Nvidia GTX 780 - 80.10.36.00.01 - 'OC edition v00'?

Hello. I flashed svl7 mod bios in my gigabyte gtx 780. I did not have any errors using nvflash 5.134.0.1 (Windows versión). But now, when I try to save the bios with nvflash, I receive the message "error: pci block chain corrupted" I tried reflashing the original bios, but the message is still showing. The pc Works ok. Do I have to be worried??

Thanks and what's your hardware setup + driver version? Some people have reported issues with the latest Nvidia driver but I don't see any difference on my Titan.

i5-2500k at 4.0GHz

G.Skill 8GB DDR3-1600

ASUS P8P67 PRO rev 3.0

EVGA 780 SC ACX

Samsung 840 Pro 256GB

Windows 7 Ultimate x64

That's the important bits. 320.18 WHQL driver. Zero issues.

Got it up to 1228/3480.

Stock BIOS - 1137/3400

Mod BIOS - 1228/3480

I have no idea if that is actually game stable, but the scaling seems pretty linear with the core clock OC. 7% gain for a 8% OC. Not bad.

Preliminary testing in Metro LL at 2560x1600 shows a 3.8% increase in FPS with a 3.4% increase in core clock.

1176/3460 modded BIOS vs. 1137/3400 stock BIOS. Going to see how far up I can go before crashing.

Finally done with Valley. 1228/3591 core/mem. 74 FPS. 3097 Score. 5.4% over max stable stock BIOS OC. Now time to test games and get despondent about how they can't handle these clocks.

Absolute max Valley numbers: 1228/3524 core/mem. 73.6 FPS. 3080 Score. 4.8% over stock SC BIOS. Nice work svl7!

Outside of crashing to the desktop when clocking too high, no odd behavior so far. It actually behaves better with your BIOS. Before with the stock BIOS it would hang hard and only a PC reset would fix it.

Try a game like Crysis 3 or metro last light to test for max clock. Valley isn't really good for max clock testing.

Yep, on stock BIOS my stable game clocks were quite a bit lower. Going to start testing games in a bit.

Yeah power target should be adjustable to 115%, but the default value is already set above the stock vbios. Stock 3d voltage shouldn't be 1.212V though... if you don't adjust anything, what's your 3d voltage?

I was referring to max voltage being 1.212V. Default is 1.162V. Default GPU clock at load is 901MHz and memory is 3005MHz.

I was able to get a stable pass on Valley with 1215/3506 at 1.212V. 72.9 FPS and 3050 score.

Previous best with stock EVGA SC BIOS was 1163/3557 at 1.187V. 70.2 FPS and 2936 score.

You're trying to back up the stock one? If so use gpuz 0.64 (yes old version) to do so. Then try flashing with NV flash with the new bios. Edit,not at my desk so may have number wrong but here is the link. http://www.techpowerup.com/forums/attachment.php?attachmentid=48112&d=1344772659

That did the trick. And NVFlash 5.134.0.1 worked just fine to flash the modded BIOS.

Power Target is now 115%. Voltage is now 1212mV. Off to run some tests.

Same error with the DOS version of NVFlash. Card is an EVGA 780 SC w/ ACX cooler and mobo is ASUS P8P67 Pro rev 3.0 if that makes any difference.

Did you use the Dos or Win version?

Command prompt within Windows 7. UAC off. Full admin rights. Is it possible 5.134 is not updated for the 780?

Welp, this has me stopped in my tracks:

Just wondering what gpu usage people are getting in sli. With a single card getting over 90 percent but in sli i'm between 70-80 percent on my 680m gtx. Don't get me wrong, the game is optimized very well from the start compared to so many other titles but is anyone getting over 90 percent in muti-gpu setups for NVidia?

It's a known issue apparently. I've seen a number of posts around the web mentioning the 90% usage with SLI. Hopefully A4 or Nvidia are looking into it.

900/1800 DPI as those are native sensor settings. Anything in between multiples of 900 gets interpolated.

On a laptop, matte all the way. Since you won't always be in control of the lighting around you, you could end up with some seriously bad glare on a glossy screen.

Just the one, a Dell U2913WM 21:9. It's great, especially for games, but a bit cramped on the desktop. Once I get around to building a bigger desk I'll liekly add a 23" accessory display for desktop work.
