My System Specs

Default Overclocking 2900XT

Hi guys, I have a watercooled 2900XT that I am working on overclocking and I need some advice. I have no troubles with temps (never gets about 60c no matter how high I overclock) but I keep getting hard-lockups at about 900mhz GPU overclock. I can run my memory up to 950 mhz with not troubles so far but the GPU won't go above 900 so I was thinking of increasing the voltage to the GPU using ATItools but I have never overvolted a GPU so I was curious what was safe and what other people have tried? I have heard of people doing 1000 mhz on these GPUs so I assume that is with overvolting, what does everybody think?

Well, I'm thinking you need to be really careful with doing that. Like with CPU's....sometimes a GPU will just not run any faster no matter how much voltages you'll push through it.

You might want to wait for some ppl who did that already to share their experiences with you.

Good Luck!
