View Full Version : Overclocking 7900 GT
03-28-06, 08:49 PM
What kind of overclock speeds are you guys getting with the 7900 GT, EVGA in particular.
With stock hsf they seem to all (many) be capable of hitting the extreme model speeds of 550/775(1550).
So Nvidia's spec is 425/650. They all seem to have the same memory etc so should all be fairly close. My friend with an EVGA can only overclock his 550/775 to about 560/785 before artifacting occurs...which is about what my BFG 474/650 can do...ie they seem to have the same stock headroom.
Cores can't go much higher than 550. Artifacts > ~550
Lots of memory goes to 900mhz I believe.
The EVGA OC I have runs at 550/790 and will clock to 565/825 before I start seeing problems.

Thanks, I'll give it a try.
Anyone know if the ram requires heatsinks when oc'ing cause I've heard it doesnt make a difference on the 7900gt.
The speeds I noted above are with no heatsinks on the ram. I noted this in the review with a pic: http://www.nvnews.net/reviews/evga_geforce_7900_gt/index.shtml
