Should I keep my P4 ES cpu?

Traded my xbox and a couple games for a P4 3.2ghz CPU and wound up with a Engineering Sample version of it. At first it gave me major headaches with my Abit IC7-G but eventually got it to work with an upgrade to the bios. Question is should I even keep this CPU or trade it in for a "regular" P4 chip? Maybe trade it for an A64? I'm not dissatisfied with it, I just don't know if I'd benefit in keeping it. Is an engineering sample less stable than a regular P4? I've included a pic just to make sure it is a sample. Intel Confidential is printed on the chip.

see that 14-16 in teh multi feild? your chip has unlocked multipliers. keep the ES.
 
Oh, it's unlocked, but only for lower multis? And only 2 extra? Are all ES like this? If so, that seams weak, unless the P4 benefits greatly from a higher FSB, so you could take it down to say 14x250 or something.

thats pretty much how they all are. some have a wider range of multis, but they are all lower than the stock multiplier. i miss the pIII days when a ES meant it was fully unlocked...
 
I think I read somewhere that different boards provided different multiplier options. Not sure where I read it, but I'm probably wrong.
 
Nah, just Abit and Asus discovered that some 3.2 p4 were actually unlocked and able to toggle b/n 16x and 14x multiplier, or there was some trick to unlock them. AFAIK, it was related to tricking mobo to run at the lowest multiplier for troubleshooting purposes or something of that sort. After that Abit and Asus came out with Bios revisions which included the hack. So it might be that hack limiting the multiplier choice on ur CPU embedded in the BIOS. :D

Of course, I might be wrong about it ;)
 
14 is the lowest multi a prescott will accept. If you had a 3.4, the range would say 14-17, 3.6, 14-18... etc. I'd keep it, drop the multiplier and try to increase bus and memory bandwidth.

A fellow trader here on the board said he would trade me my Xbox bundle for a 3.2ghz P4 CPU and it turned out to be an ES. I was worried at first because when I received it it didn't have the regular markings on the CPU itself. 3.2ghz was written on it with a marker.

And BTW, is this thing supposed to idle at around 43C or am I doing some thing wrong? I'm using a Thermaltake BigWater watercooling setup. It is by no means made for overclocking. I just bought it as an all in one solution to get a better idea of how watercooling works.
