The crew over at Nordic Hardware have pumped out some of the first overclocked benchmark results on the web of a CrossFire Radeon HD 2900 XT setup.
They nearly gave up trying to get it to work at all, but after a lot of stuffing around have come through with the goods. Using a pair of ASUS Radeon HD 2900 XT cards they were able to overclock the GPUs to 880 MHz and the memory to 950 MHz (along with improved memory latencies as well).
The system itself comprises an Intel Core 2 Extreme QX6700 processor overclocked to 3762 MHz on air using an ASUS P5W DH Deluxe motherboard, and a pair of Corsair Dominator modules at 456 MHz with latencies of 3-3-3-5.
Given the processor was only air cooled with an average overclock, the benchmark results were quite nice indeed. They managed to score 20,278 points in 3DMark06 with the SM2.0 and SM3.0 scores at 7,989 and 9,449 respectively.
Even better results are on the way, as they plan to give it another whirl using more extreme cooling, liquid nitrogen to be exact.
We (Kinc) have been trying to get Radeon HD 2900 XT CrossFire to overclock for quite some time now. We were about to give up after trying practically everything you can imagine, but that's when AMD stepped up and saved the day. Even though the method is still very crude and far from easy to perform, we can now present the first results with an overclocked ASUS Radeon HD 2900 XT CrossFire configuration.
