So what max temp do I stop with the VRMs on my 7950?

post #1 of 10
Thread Starter 
Just put my video card under water. Before my max was 1100/1500 stable on air with that dual fan from sapphire. Well it's sitting under water with the Swiftech Komodo and my clocks are currently 1250/1800.

GPU has yet to go above 45C under full load and my VRMS bounce from 65-70C. VDDC is 1350 currently.

You can hit 1900-2000 with 1.7 memory volt.Tahiti is temp sensitive so care with your temps. Happy oc thumb.gif

The absolute max is around 100-110 but after 80-85 you lose some oc potential

I need the winter to come again to bench this high on air tongue.gif

Nice clocks!!!! It's still chilly here in MA I've been doing a lot of benching with my windows open. Delidded 3770k at 4.8Ghz at 1.5v never goes above 60c and my two 7950's at 1165/1600 never pass 47c and VRM's never pass 59c. I used to hate the winter, but ever since I built my rig I'm loving drinking some hot chocolate and doing some gaming and benching. For the first time, I feel lucky to live in New England!!! Will be keeping an eye on this thread.

I can stand anything being cold since I'm always boiling hot but cold feet is something I will not tolerate! haha.

Going to bed but I'm going to see how much more I can push it tomorrow. I don't think I'll be getting anywhere passed 1250 on the GPU though, and I'm not even sure my CPU would allow it since it may bottleneck. I had to open it up from 3.4 to 4.0 just to get the 1150 OC to benefit.

post #10 of 10
Yea when I put the rig right next to the window with a shop fan blowing at my cards they go down to about 16c haha. I've only done that once though I usually just open the windows with my rig on the other side of the room and then aim my fan at the cards
