i doubt the Athlon II 630 X4 is BE so have you hit all your multipliers yet?
if it won't run steady at 1600mhz, increase the dram voltage by a little and see if it gets any more stable.
Since you're overclocking FSB, if your ram doesn't go well past 1600mhz, just set it lower so it doesn't go above 1600 with the oc.
Finding D-ram timing is a waste of time on my end, i just leave my crap at 999-24. runs fine lmao.
It's not a Black Edition-- you're right, I'm using FSB. Here's the odd thing: It works fine at 1600 Mhz when the FSB is right around 200, but when it gets increased things get unstable even when the RAM speed is set to 1333 (so that the net RAM speed is right around 1600). When I set the ram to 1066, it's fine and I can get to the FSB wall (just above 240 Mhz). Increasing RAM voltage doesn't help. Do Athlon IIs have weak memory controllers? I don't think the RAM itself is the issue.
So basically, will I see improved performance over my stock specs even if the RAM is ultimately a little slower than it originally was?
