First of all, my specs:
e8500 currently @ 3.6ghz (400fsb x 9.0) , stock cooling
2 x 1gb ddr2-800 @ manufacturer reported timings, 5-5-5-15 (also 400fsb, 1:1 ratio)
asus p5b mobo
Anyways, my vcore is currently at 1.3250V. This is the lowest stable vcore I've been able to obtain for 400 fsb. My max temps under load are around 64C. If I got an aftermarket cooler and some arctic silver 5, I'm aware that naturally my temps would decrease significantly. But the vcore would still remain at 1.3250V. According to intel 1.3625V is the max voltage my cpu can handle, am I playing with fire, or is this ok?
One more question. Apparently XP thinks my multi is at the default 9.5, as it's reporting my CPU speed as 3.80ghz (400fsb x 9.5). CPU-z correctly recognizes the 9.0 multi. Should I be worried about this?
so, i should have no problem setting the fsb to 400 right? heatwise.
could i just leave the vcore alone? what is the default?
If you get a good heat sink, you won't have any problem. The default is ~1.15v. You won't be able to get it to 3.8ghz on default voltage though. You could probably get it to 3.4 or maybe 3.5 on default voltage before you start having stability problems.
