ASUS DCII 580 Voltage question

post #1 of 18
Thread Starter 
Say i am kinda new to overclocking, and i am working on overclocking my card, i am going in 15Mhz increments and using heaven 2.5 and soon 3dmark11. i have pushed my card to 935 with voltage of 1100 (1.1) and i get artifacts like crazy. Is that normal? I am stable at 920.

But my main question is do i void my warranty if i go over 1.1 voltage? or is it 1.2?

1.1v is usually not enough for 935 core. With that cooler, you'll have no problem pushin 1.213v. You won't void the warranty doing past 1.1v.

1.1v for 920 core is pretty good

Push the slider as far as it goes, I don't recall the exact value. It's a good card, it can handle it. As for the warranty, I'm not sure the exact details but they specifically advertise it for overclocking/overvolting so I doubt it would be an issue. Also if you don't flash the bios to a higher base voltage value I don't really see how they can could tell definitively anyway.

I just got it to 940 core with a stable 1.138V both in Heaven 2.5 and in 3dmark11. but i pushed it to 950 with a 1.15V and i ran heaven 2.5 but i got a few artifacts stable but a few artifacts. But 1.15 is the end of the voltage slider. Do i need to flash the bios to unlock it to go further then 1.15 and if i do that i will void my warranty :/?

If you decide to flash here is a link to my BIOS. It's based off the original ASUS GTX 580 DCuII BIOS, so all the BIOS identifiers should be identical, except that some limits have been increased. Of course the Checksum/MD5 of this BIOS will not match your original BIOS. I don't know if they would void your warranty if they discovered the BIOS flash, but I doubt it. Hard modding the card however will void your warranty.

If you've never done a flash (mobo or otherwise) and you're not comfortable doing it, and you're worried about the warranty then just don't do it. Set the slider to 1.1v and run it as high as it'll go without artifacts in Heaven. Lock your fans at 55% and you'll be good to go.
