I've now got my eVGA 7900 GT CO SC overclocked at 730/846 or 730/1692. Currently running the 93.81 drivers and have ran BF2142 and NHL07 back-to-back with no problems. Still idles at around 44' C, depending on the weather and heater in the house. I'll update benchmarks in my Sig as soon as I can run the tests, probably Tuesday. Just thought I'd share my new high overclock.
P.S. This is with the Core VMod only. No Memory VMod applied.
Here's to overclocks!
