Im confused

[Bleed]

Im confused about something, when I was still on air and using a zalman 7000AlCu HSF, I could get to as high as 300fsb on 5/4 ratio. Now Ive switched to watercooling, my temps only dropped a couple of degrees. now for my problem, with watercooling I could no longer get to 280fsb, my systems reboots if I go any higher. right now im clocked at 275fsb rock stable, but a few months ago i was stable at 290fsb on air. anyone know what the problem is coz I sure dont

What Vcore were you running for that time, it could be one of the degradation factors.

Nothing else changed? Water cooling uses more power how do the voltage rails look?

Could be the power supply. As already mentioned.

Did you change anything else..maybe you changed the memory voltage by a very small amount without relizing it?

I would be happy and content with 275 though. MY FSB is 100mhz on both my P2 and P4..lol

nothings really change, Vdimm and Vcore. I even bought an Antec TP 480 to replace my antec SL450 PSU because I also thought it was a PSU problem. when I was still on air, I usually set my fsb to 290 for gaming, vcore 1.575 and everything went fine. This really got me confused, Im even thinking of going back to aircooling just to see if everything goes back to the way it was

right now im at stock Vcore.

Try it @ about 1.6v.
