Hey there, I just started messing around with oc'ing today. Here's what I've found so far (if this helps).
system:
a64 3000+ running
2x512 mushkin pc3200 2222 weekend special
msi k8n neo2 platinum mb
Enermax 495ax-yacketyshmackety powersupply (highly recommend this. 18a to both rails (split +12v), active pfc, serial ata, pci e. Everything I've ever wanted.
Thermaltake k8 silentboost (lapped to boot!)
arctic silver 5 thermal paste.
I failed at 300fsb. Had to jumper reset.
The highest that I tested successfully was 295. I am now running at 290 (I can live without a few extra mhz with what I amg etting away with) to give my proc some stress breathing room.
I have a 9x multiplier:
2610mhz 9x290
ht= 3x (4x locks up)
cpu voltage is 1.55v*
mem voltage is 1.75v
memory timings set to manual
cool n quiet disabled
aggressive timings disabled
spread spectrum disabled
memory clock is at 166 (ddr speed is 241mhz). I am currenly running through memtest to see if it is stabile. I am testing timings. Currently it's set to 2.5, 4, 3, 10. (
Mushkin has an articleon their site about athlon 64's having a wierd memory timing error once a month due to cas2ras timing issues. I don't know how accurate it is, I have never seen it validated, but I figured I would keep my cas2ras up 1 higher than normal. It's minimal performance sacrafice when you consider I'm running at 800mhz oc.
I was really annoyed by the poor documentation of the mb's features. The memory clock pissed me off. It says that it is the setting at which the max memory speed will be locked at. It's wrong.
*Also, maybe you guys can help me out! What does CPU VID mean? I am assuming it has something to do with voltage. howerver, changing this has no effect on the voltage of my processor. When I go to the the health screen, it still lists cpu core voltage as 1.4 no matter what I change that too. I have found that I have to change the vid +8% in order to boost my cpu voltage, and that changign the cpu vid does nothing for me. Is this the same for eveyrone else? I would recommend everyone to use the pc health page in bios to validate there voltages.
I am also really curious about hypertransports effect on performance. Currently I'm running at 870mhz.
I am wondering if it's hurting me more, than if I scaled back and ran maybe 260x4 or whatever I can get away with. I am guessing that ultimately, the 270 mhz would make up for the slower ht. What's your guys take on it?
