Anyone with overclocked DDR memory?

[Ianxxx]

I've done a bit of checking and it seems that if I don't run memory at default speed of 400mhz I eventually get my mouse twitching, I can overclock my processor no probs, I can adjust latency of memory as fast as it can go. but if I increase memory bus speed I get this problem, anyone found similar?

No probs here bud running at 450.

I overclocked my CPU from 2.0 to 2.2 (X2 3800+) and it auto overclocked my mem from 400 to 440, but in Leo it shows as 400 still, windows shows 440, my mouse was choppy on 10.5.1 but seems fine on 10.5.2
