Return of the lame overclock (help!)

post #1 of 3
Thread Starter 
Last time my friend tried to overclock his 2.0 northwood we had troubles around 2.3Ghz and never figured it out. Now he's got a new processor (2.53Ghz 133FSB) so we're back at it again but with similar or worse results as far as % OC goes. It craps out around 2.7Ghz with any voltage (we tried up to 1.65V) and it's just mind boggling. I'm pretty sure it's not the ram because it was underclocked at the time because we were just working on the CPU. Also PCI/AGP locks are present and enabled according to the bios. Any help? System specs are as follows:

P4 2.53Ghz 133FSB (C1 stepping in cpu-z)
EPoX EP-4PDA3I
350 watt power supply (12A on the 12V and it's a really hefty power supply if sheer weight counts for anything)
2X 512MB sticks DDR 266 in dual channel (tried with just one stick as well)
gforce 4 TI 4600 (also tried with a radeon 9550, but no help)
120GB ATA 100 hard drive (samsung spinpoint)
1X dvd burner

I've been looking into that first. Why so much weight? Maybe it's the cheap steel casing. And also Epox aren't the greatest overclocking boards for an Intel CPU, specially back in the 865PE days, the best ones were IC7 by ABIT and P4x by ASUS.

BTW, 12A equal to 144W of power, so maybe a PSU with at least 18A would help just a tad more.

Ok. Well I don't really know about that power supply... it's just heavy. I don't exactly recall the brand but it was like PC cooling man or something like that. Not PCP&C. Anyway, I'll try another power supply temporarily just to see if that helps. Also,how do I know if a power supply is being overloaded? As it was, the idle voltage was 12.4 and load was 12.2, not bad at all if you ask me. I think 3.3 was in the 2.9 range though, although that could have just as easily been a misreading it was so off.
