Sorry for the questions but I am kinda new to oc'ing and definently new to AMD and DDR systems. When I set the memory to 166MHz and run it at cas 2 (corsair recommended settings), it runs great. Sandra scores around 2100 or so for mem benchmark (kinda low?) and 3dmark scores 13569. If I up the mem to 200 MHz even setting it at SPD, my performance drops way down. I lose over 3k on 3dmark and Sandra drops to 1300+. I know that is pushing the memory and its not synching with the fsb (all stock/auto settings in bios) but shouldnt I get at least a little improvement instead of the dramatic :) drops I am getting? I have tried a little fsb oc'ing but I guess I dont wanna push my luck. Only 1 side intake and 2 rear output fans and cpu has retail fan/hs. Any thoughts, ideas, suggestions??
Thanks In Advance

The drop your experiencing is a little suprising to me but its mainly due to using the stock timings and not running at 1:1 with the FSB. If your using the stock HSF I would strongly recommend getting a new HSF. An SLK800 would come to mind, the best performing heatsink and only about $30.
 
I will be upgrading the cpu HSF within a week or 2. Comp show soon at arena here. I have checked out that HS.....I will give it a try. I wanted to upgrade the cooling anyways. I run about 37-40+c or so at idle and 43-45c stressed. I know this isnt too high, still a little higher then I'd like to see. I am also going to add 2 more intake fans (1 as hd cooler). That ought to help a little I hope. Anyways, it still leaves me a little curios about the Sandra results and upgraded mem? Would upgrading the mem to a higher rating help me out at all? Also, just remember, anyone know if running 2 sticks of mem (pc2700 or higher) on this mobo cause probs or...?
