hello, I got a p4 prescott 3.0e from an oem dealer, and I noticed in CPU-z it read model 3, stepping 3, but revision C0. This is weird becuase out of all the prescott cpu-z pics I've seen none have shown that C0 revision and I'm noticing that my cpu overclocks differently than others, I have to use totally different voltages, with certain fsb's than other people do. I was just wondering If someone could help me out here becuase I'm having toruble overclokcing this, and I was hoping for a point in the right direction.
Ya, i've done some looking around for my cpu and I found an entry in the ABIT-USA forums about o/c'ing these, most people got them up to around 3.6 and above, but my cpu can't go above 3.52 ghz (235 FSB) with 1.46v, most likely my oem dealer sold me a lemon CPU which refuses to o/c properly. I've tested for heat issues and it isn't heat holding me back, i've tested 235 fsb even at 1.55v and the temp. never exceeded 55C. I'm thinking of trading it in to him and getting a 3.2ghz one in RETAIL BOX, and paying the difference. Trust me, this guy doesnt know [-peep-] about this kind of stuff like overclocking and modding and [-peep-], I broke a 6800le trying to mod the heatsink, I brought it into him becuase it was still under warrenty, and he took it without a problem, he had no clue. Anyway, If he give me about 150 for this one, I can grab a 3.2 for 78 bucks, and im willing to put money on it that it will o/c perfectly and probably hit 3.9 or 4 ghz easy on air. The airflow I got in my case is amazing and I got a nice big TT PIPE101 heatpipe heatsink on the cpu so it'll stay nice and cool, no need for watercooling.
Do you think he has an engineering sample. Those are unlocked, are they not?

And the sign says "You got to have a membership card to get inside" Huh
So I got me a pen and paper And I made up my own little sign</pre><p></font color=red>
Well that answers my question a bit as to why I cant hit 4 ghz with this thing, so in all reality, I dont really have a "lemon" cpu, I just have one of Intel screwups. I'm already planning on trading this in and getting a 3.2e, not sure which stepping, but I hope it's aty least d0 and not another c0, becuase then it'll be a waste of my 78 bucks =). And no, this is not an engineering sample, if it was i'd be jumping for joy and have a party, but it has a locked multiplier. I have this thing at like 3.54 stable at 1.46v for about 7 hours in prime95 so far, but starcraft crashes for some random reason, maybe i need to patch it.
