P4 2.4A C1 Overclocking Question

[wackyquacky]

Newbie here so bare with me. I have recently purchased a P4 2.4A C1. This chip overclocks pretty well in my setup, running stable at 122FSB under Prime95. Now that was before I switched out my Enermax 350W power supply for the antec trueblue 480W that is currently in my case. Now, after switching, the cpu boots but will not run stable at 122FSB in windows. It also craps out at 120FSB after 6-7 hours of prime95. Is the problem due to the difference in the PSUs? I thought it wouldn't be because Antec (at least what I heard) made quality PSUs. Please give me a hand.

My setup:
P4 2.4A C1 @ 2.88 (default vcore)
Iwill P4HT
1GB Samsung PC2700 (2X512MB)
Swiftech MCX4000 w/ TMD Fan
Antec Trueblue 480W
Pioneer A05
TDK 24X12X32
Lite-on 16X DVD-rom
Maxtor 60GB 7200rpm
Maxtor 40GB 5400rpm
All in a Lian-Li stock PC65 case w/ 4 fans

I wouldn't think so, but switch it back and see what happens.

bad PSU?

Well, I switched it out after my last post. Booted at 122FSB again but froze at windows. Brought it down to 120FSB, and the same thing happened. Error at hour 4.

I remember reading that the C1's were having a weird problem with Prime95, but stability everywhere else was fine.

 

[wackyquacky]

is there another program that you suggest is use w/ p4 c1's then? Also, i tried playing some C&C generals at 120FSB (it's a pretty demanding game on the system) and it crashes the game or reboots totally after maybe 10 mins of gameplay. Machine is stable at stock fsb.

Sounds like a overheating issue. Are you monitoring your temps?

 

[wackyquacky]

temps are stable at 39 idle, a little hot at 52 full load. not sure if that's doing it. maybe i should switch that tmd fan w/ something a little beefier.
