NVIDIA GTX 680 OVERCLOCK DRIVER
Perhaps the company will consider enabling additional scalability in its driver moving forward. We started down the road of disabling Ultra-Low Power States and registry hacks to get at more speed, but quickly decided that circumventing beneficial aspects of the hardware was a step too far. I also upped the fan curve just a bit to keep it nice and cool. I upped the boost from 1137MHz to 1202mhz and memory from 6008MHz to 6200MHz.
NVIDIA GTX 680 OVERCLOCK SERIES
I overclocked it to the same speeds as the Gibabyte Super Overclock Series GeForce GTX 680 GV-N680SO-2GD. It’s a little disappointing, then, that the Catalyst Control Center driver tops out at 1125/1575 MHz. I own a Gigabyte GV-N680OC-2GD GeForce GTX 680 OC 2GB. Overall, it’s pretty easy to see that AMD’s Radeon HD 7970 has more to gain from an aggressive overclock than Nvidia’s GeForce GTX 680. For whatever reason GTX 680 has a 15fps lead in GT1 but loses by 10fps in GT4, with the other tests being very close. That lead is maintained when both cards get overclocked. It looks like 7970 on LN2 maxed out at 1800Mhz Core overclock results in a slightly higher 3DMark11 P score of 15035 (vs 14912) and Graphics score of 15334 (vs 14957). The Radeon HD 7970 was already faster than Nvidia’s GeForce GTX 680 with 4x MSAA applied to Metro 2033.
