2.4 stable. But that's not very impressive. I've tried higher, but I seem to have some problems with my RAM. For example, I set the CPU setting to 300 x 9 multiplier to get to 2.7 ghz. That works fine with a voltage bump. But, when I set the RAM above 200 (which is really 100 on this mobo, signaling what I believe to be a .5 divider), I run into problems. The way I understand all of this oc'ing on the mobo, I should be able to use the 266 setting on the RAM, which is the .66 divider, and get 198 (300*.66 = 198), which of course you double for the double data rate, and come in just under 400. My RAM, while very early DDR 400, runs at 400 when the cpu is set to stock, so I'm very confused. If I add voltage to the RAM, I can sometimes get into Windows, but still have Prime 95 crashes. Why wouldn't the RAM work at a touch under 400 with CPU overclocked, but will work at 400 without the CPU overclocked? Am I missing something, or do I misunderstand the interplay between "CPU setting," "RAM Setting" etc.???
I do have latest bios.
Oh, HT is set to "3." So That shouldn't be the problem. HT should be at 900, so that's less than the 1000 barrier.
For reference, I have a very early (one of first ones on first day sold) Asus A8N-SLI Deluxe mobo.
