. Best 4770 OC'ing thread I can find! And it's still active aswell
Previously I was running Sapphire 4770 at 825/1075, stock everything, BIOS, volts etc. 100% stable and 0 artifacts with FurMark running at these settings - Windowed / 1024x768 / MSAA 2x / Stability Test. 1280x1024 is my desktop resolution.
It seems now but there is a way to volt mod your card without the need to flash it with the Asus TOP BIOS and use SmartDoctor
, it's called...
MSI AfterBurner > http://event.msi.com/vga/afterburner/
Now I'm running at 900/1030 @ 1.187v with the FurMark settings above and just like before, 100% stable, 0 artifacts
.MSI AfterBurner uses the same method to OC as CCC so you are still stuck with the 830/850 limit, so you need to use RivaTuner. Afterburner to OC the volts, RivaTuner to OC the Core/Mem.
The max volts you can do in Afterburner is 1.2v.
This is a great alternative for people who want to keep their stock BIOS and not risk flashing over it with the Asus TOP BIOS
My card could definitely do higher and bench higher but in games is the only place it matters for me, so it has to be stable.
O' and I forgot to mention, I run my fan at a constant 35% 24/7, so those clocks + FurMark settings are all at 35% fan. At the 900/1030 FurMark test it got up to 98c but no way it's going to do that in a game so I'm happy
One question I have been wondering is, does the Asus TOP BIOS OC better than the other bioses? I'm talking about JUST the Mem/Core, no voltage change at all. Because I'm reading all these people getting 900+ on the core on stock volts and I can't even do 850/1000 stock volts on my stock Sapphire BIOS without crashing.
So is there something about the Asus TOP BIOS that OC's better other than the ability to change the voltage?Edit:
It seems you don't even need RivaTuner now
! I didn't realise that MSI AfterBurner can push past the CCC limits though it is not documented.
|1) Go to installed directory of MSI Afterburner, default: C:\\Program file\\MSI Afterburner
2) Use notepad to edit â€œMSIAfterburner.cfgâ€
3) Change the parameter of â€œEnableUnofficialOverclockingâ€ from â€œ0â€ to â€œ1â€
This is great
. 1 program to do everything and no BIOS flash
