Hey,
Overclocking for the first time... Well I'm currently at an FSB of 215MHz, completely stable etc etc. My aim is just to get to 225MHz (-> 3.8GHz). It's winter here so I've been heating my room nice and hot to see what my temps could get up to in summer. Still ok but I thought I'll get an intake fan since I didn't have one. Drilled some holes, put in a cheap fan all good. Turn my comp on no probs, temps down a bit.
All good there. Go to restart my computer to get to the BIOS and it doesn't quite make it. Gets to 'memory runs in dual channel interleaved'... but restarts before the IDE channels stuff comes up and also before I can get into the BIOS (even though it says entering BIOS). Restarts again until reverts to stock settings and boots fine.
Did some experiments.
I unplugged the new fan, no change.
Tried lowering the RAM speed so its not 1:1 and loosened off timings, same prob.
I tried different FSB speeds:
220 same prob but sometimes doesnt even revert back to original settings and just keeps restarting until I force it off.
Stock restarts fine.
After reverting to stock and restarting I changed back to my current stable settings (215MHz) and it boots fine! So it can restart from stock into 215, but not just 215 restarting.
So basically I can't restart my computer when it's overclocked (haven't tried lower FSBs than 215 though). But if I force it off and start up cold it boots fine and is stable.
And this never happened until I after turning my comp on after the day or so I had it unplugged with my installing fan/drilling etc. Before then this problem never happened and I had no probs whatsoever at 215MHz
Any ideas?
My system:
Gigabyte GA-8I915P-G
P4 HT 550 3.4GHz @ 3.67GHz
Corsair ValueSelect RAM DDR400 2X 1GB @ DDR430 2.5-3-3-7
XFX Geforce 7900GS XXX Edition, factory OC @ 600MHz
PSU is Acbel 450W
Those are the important bits I guess. Using latest BIOS version F7. Oh and CPU overvolted to ~1.41 V from ~1.38 V.
