    Heh, this is more of a "Should I buy?" question, but w/e. Well, since I probably wont be building my new comp until June at the earliest, as I want all most bugs in PCI-E, Socket-939, etc. to be worked out, I thought I might pop a new CPU in here for a little performance boost. Now that the 800FSB CPU's have been out long enough, the old "A" P4's are becoming dirt cheap. I was looking around on eBay and they have brand new ones starting at $10, all of em under $50. This 1.9 Williamette is ok, but it has a .18 micron process and a 256K cache. If I was to get, say, a 2.2A P4 with a 512K cache and a .13 micron process, would that give me a performance boost? Granted it wouldnt be great, but an extra 300MHz in speed, twice the cache, and a cooler running CPU that requires less power would be better for my system, right? I only have a 250watt PSU running 2HDD's, a Ti4200, and 3 fans. Anyways, I think I'm going to go ahead with it, lemme know what you think of if there's any reason I shouldnt. : peace2: Mista K6

    EDIT: Ok, one thing I did notice was that my CPU runs at 1.75v (I'm guessing because of the .18 micron process). The new P4 would run at 1.525v. Is that going to screw up my CPU? Or will the i850 chipset automatically decrease the voltage to 1.525 when I pop the new CPU in? Thx a lot!

    Its really hard to know exactly, when we don't know exactly what Intel i850 board it is. If your board supports the lower voltage, and you can get them for $10 off ebay, then yes.
    I even think that for $10, it would be woth it with just the voltage drop and cache increase.

    My sentiments exactly :D .

    Well, I serached around using AIDA32, the Intel site, and the Dell site for about an hour and a half and couldnt find a thing, so I just ended up calling them and the guy plugged in my assembly number and he said it should be fine, so good news there. I'm still not 100% sure which i850 chipset it is, but after doing some research I'm pretty sure its an i850EMD2. Anyways, other thoughts? Thx, : peace2: Mista K6

    Check your board and see what the lowest vcore setting is.

    Dell comp's have very limited BIOS, there's no way I can check that. But if the Dell guy said it was a go, I'll do it. If my comp fries, I'll blame them and get a new one :p (probably wont work like that tho). : peace2: Mista K6

    I'd put it in and check CPU-Z and see if it tells you the current vcore. If its at 1.75v shut it off.

    It is at 1.75v, all Williamette's are. What am I supposed to shut off?

    Ahhh, cause then I'd be frying it :p . Sorry, didnt catch that.

    Ok, the other thing I'm wondering about is should I get a new HSF. In theory this thing should run cooler so I shouldnt need a new one, as my current HSF is barely warm after running for a full day. My current cooling system is a little different, if anything its almost like BTX cooling, see the pic. The 60mm blows directly through the fins of the HS and then the big black thing is a 92x92x30mm fan that sucks the air out. As said, everything is frigid. So, is a new HSF in order? Granted that when I put it on the new CPU, I'll use Arctic silver 5, not the crap Dell uses, and I might even lap it a bit, depending on how bad it is. Anyways, thoughts? Thx, : peace2: Mista K6

    If you buy the new cpu boxed (with intels hsf) then just use that one as you won't be able to oc with that board anyway. :2cents:
