Shamino Gets 1165MHz Core Clock on GeForce GTX 480 Video Card Using LN2
Peter “Shamino” Tan is a legend in the overclocking community and over the weekend he has pushed a GeForce GTX 480 graphics card higher than anyone else that I have seen thanks to LN2 cooling and his years of expertise in overclocking hardware. By using LN2 cooling on a GeForce GTX 480 video card he was able to take the core clock from 700MHz up to 1165MHz, which is an amazing 66% overclock! He then used an Intel Xeon E5640 processor at 4GHz and was able to score just shy of 30,000 3DMarks in the Performance test of 3DMark Vantage. Very impressive results, but Shamino says that the GeForce GTX 480 is memory bandwidth limited and that better memory clocking is needed at these levels. That blows away our 800MHz core overclock that we got when overclocking with air cooling. Shamino made an interesting comment in the forum thread that to get any higher than 2330MHz on the shader that he needs LHe as he is seeing ‘too hot artifacts’ when overclocking. This guy is pretty extreme!
Looks like it needs better Memory clocking, after 1100/2200, it is extreme bandwidth limited in Vantage. I think maybe -70+C needed for 1000 but 1100 was around -100+, i was all over the place with volts and temps so not quite sure, do know that i was running -140+c for 1150. Left the memory alone at 2200 and focused on pushing the shader, 2330 @ -170C, any higher , it needs LHe I think I’m seeing the ‘too hot artifacts’
