No problem.....oh, the vGPU should give slightly higher volts loaded (3d app)than at idle (desktop).Quote:

My ASUS 8800GT:
Before i was able to benchmark at 740/1825/1900 and now i am able to do it at 770/1890/1900... not bad ;)
I have to do something with the vram frecuency, if i try to go over that speed playing crysis i ALWAYS get red squares all over the screen and it freezes... :(
I have successfully flashed my Club3D 8800GT, so now it runs quite stable at 771/1836/1000. Before flash the core was 720. So quite impressive.
So, has anyone tried the jasons method with more then 1.1V? Does it work?
edit:
I can confirm that Jason's type of method does not correct the voltage to 1.2V, but stays at ~1.13V. Also changing all the others VIDs to 1.2V doesn't work either. Anyway, it is good improvement for me (50MHz on core).
Can anyone tell me if this works for an evga superclocked 8800gt?
Or at least what your experience/results have been...
It depends on every single card.. Try it, you cant break anything:)
wich bios are you guys using to flash your card.....ones with good results????
I flashed my KO with my OWN stock Bios that I just added the 1.1 option to.
In general our own card BIOS. Minimum risk:)
Yes, but some bioses will give you higher overclocks. I can up you the orig bios I have and you can check LOLQuote:

OK thats about RAM timings.. But anyway, lower timings with lower frequency give you almost the same result as higher frequency with higher timings. So therefore actually no improvement. I thought we were talking about voltage tweak inside BIOS...
Ok guys, I only have a USB flash stick, but no floppy drive. How can I flash my Inno3D 8800GT BIOS?
Thanks
There are some ways with a USB stick but it's not that easy (Google it ;)). Someone said he succeeded to flash by creating a bootable MS DOS CD with Nero. After booting on the CD you should be able to browse your HD.Quote:

Are there any modified bioses for the 8800 GTX? I have a Gainward 8800GTX and it isnt good at overclocking. The highest I got this thing to so far is 610/1470/970.
Hi! My Zotac (660-Version) is flashed to 730/995/1800 and runs really great. I have used another bios from here
http://extreme.pcgameshardware.de/showthread.php?t=5170
because it works better than the one of the first posting here. That one is also stable with ATI-Tool and 3dMark06, but the Crysis-Demo only shows a :wth: With my bios everything´s fine.
My card is cooled by Accelero S1 with a lovely Scythe-fan. No possibility to get it over 60 °C. Is there any possibility to reach a higher GPU-voltage than 1,13 V by biosflash? Up to 1,2 of 1,25 V I would really try it ...
If so I could send my actual bios for reworking :D
I've successfully flashed my Inno3D 8800GT BIOS with 1.1V using a bootable USB flash disk.
Testing to find my max overclocks now.
Before 1.05V
GPU: 700MHz
Shaders: 1700MHz
Memory: 1000MHz
After 1.1V
GPU: 742MHz
Shaders: 1782MHz
Memory: 1000MHz
I'm keeping my memory at 950MHz. Is the speculation about the cards failing with the RAM set at 1000MHz true?
Everyone is just referring to subjective results aka "max stable frequency". Has any of you simply measured the result with a multimeter? It takes a few seconds and is highly objective...
Some people did the measurement and confirmed it increases the voltage. They also confirmed that it is not possible to go higher with a bios flash.Quote:

So I think we can conclude that the bios mod really increases the Vcore ;)
Thanks for the link. I tried to find a good tutorial last time but only found obscure explanation or some of them requiring a floppy :rolleyes:Quote:

I did measure the vGPU, and it is 1.1337V with the biosmoda against 1.057V with the stock bios.Quote:

With S1 and a 100 (not 120!) mm fan of Scythe approx. @900 upm I never get more than 60°C. Clocks are 730/995/1800 - ever, because flashed!
And temps with stock cooler at these clocks and voltage(if you tried)?
