Help overclocking GTX 580 3GB Classified Hydro

post #1 of 5
Thread Starter 
I need help overclocking this thing.
Here are the two I'm using, which one do I change and by how much?

I want a safe overclock, what are the max and safe ranges for vcore on these cards? I was thinking about putting the vcore to safe voltage and just increasing the clock (not sure which one) a little at a time.

I have been messing with my 2600k for a while but I am clueless on these graphics cards. Input will be appreciated and rewarded, thanks.

Here is my card:

Since your cards are built for overclocking and are on water you can run them with pretty high vcore without damaging them as long as you have adequate enough rads. 1.15vcore is pretty safe and you should probably start off with that and see where it gets you. I've ran 1.21Vcore through my gtx480's while under water and they did fine. Your cards have way better components than my gtx480's so you should be fine unless you hardmod for more volts. Also make sure you monitor your temps while stability testing.

I'm clocked at

900/1800/2004 @ 1.1v, I could push my memory if I needed to

Max temp is always under 40C with crysis 2 or BF3

Seeing that you have the classified. You can hit 1000 core easily

Looks like my stock voltage is already 1.1v
