My AM2 4200+ X2 Overclock
Setup:
Athlon 64 X2 4200+ (2.2 GHz stock) with Arctic Cooling Freezer 64 pro
Asus M2N-SLI Deluxe (BIOS Rev. 0304)
1GB Corsair XMS2 DDR2 800 (5-5-5-12 @ 1.9V stock)
Isolating the processor, I was able to push it to 240 x 11 = 2.64 GHz @ 1.45V (see note below). I didn't try to push it much farther because I was anxious to move on to OCing my RAM.
The RAM was stable with 250 reference clock and 5-5-5-12, 2T @ 2.2V. I tried various combinations of 1T, 4-4-4-9 @ 2.3V with sporadic success... it would POST but Windows wouldn't load. I even lowered the reference clock to 240 and still couldn't get it to work with tight timings. I was scared to up the voltage more than 2.3V... should I be?
For now, I have it running at 240 ref clock, 11x multiplier (2.64 GHz), but lowered the RAM multiplier so it runs at 667 (4-4-4-9, 1T @ 1.9V) instead of 800, but if my math is correct, 667 with a 240 ref clock is still right at 800, right? That's what I expected but with that setup I got about 200 marks lower on 3DMark05 than I do with everything stock. So my underclocked RAM with a higher reference clock to balance things out still drops performance?
Note:
So, I stopped pushing my processor because I wasn't sure how much was too much voltage. I was worried because no matter what I set the VCORE to in BIOS, it's always a little big higher in reality. The hardware monitor in BIOS, as well as PC Probe II, reports 1.49V to 1.51V when I have it set at 1.45V. So when I say 2.64 GHz @ 1.45V, it's really like 1.5V. Should I not worry about increasing the VCORE more as long as my load temp doesn't reach 60 C? At 1.45 (1.5) it reached 57 C, but that's because my case is hot as hell at 38 C under load. I need to work on that.
More resuslts to come. This is just after one evening of playing around.
