Galaxy GTX 465 in SLI
When it came to overclocking in SLI, I really wanted to achieve a 708MHz core and a 902MHz (or 3608MHz QDR) memory clock. What this would've given us was a 100MHz increase on the core and 100MHz or (400MHz QDR) increase on the memory.
Unfortunately in SLI we didn't have that much luck; under some benchmarks we could get a complete run and others would freeze up. So we rounded the numbers off to 700MHz on the core and 900MHz (or 3600MHz QDR) on the memory.
Just those few MHz shaved off the top gave us a stable run. While we achieved 725MHz core in our single card test, the fact that we're now dealing with two cards close together means we're going to get a bit more heat.
Not to take anything away from the setup, though, this is an impressive overclock nonetheless. Looking above, you can see we ended with a 900MHz Core, 1400MHz Shader Clock and 3600MHz QDR memory clock.
We want to see some good performance and we've got our fingers crossed these numbers are going to give us the numbers we want to see.
