PIII 700e HS/Fan help

[RabeaticSquirrel]

Man do I feel dumb. But here goes. I'm looking to build a new machine. When someone says that, most folks usually say, what's it going to be used for? Answer: overclocking. That's it. Just a toy, if I burn it up, Oh well. With that said....the PIII 700e looks like my best choice for a descent priced CPU to hit the 1 gig mark. If I'm right, the 700e is designed for a 100 mhz bus right? So if I put it on a CUSL2-M board, rated for 133 mhz, and use mushkin HSDRAM rated for 150 mhz, I should be able to hit some good speeds after burn in right? Or would the 133mhz 700eb be a better choice? If so, why?

Secondly everyone seems to recommend an Alpha HS/Fan for just about any chip. Would this be the best choice for me (outside of a peltier or water solution)? If so, do you know any good places to purchase an Alpha HS/FAN?

your post looked lonely with no response, so here goes
If you intend to overclock, definitely get the "e", NOT the "eb"( not enough headroom left with the EB, as you are starting out at 133mhz already).
As far as memory, Mushkin has been "berry berry good, to me". Check the reviews page on Anand's front doorstep, and see if there is an appreciable difference between the HS 150, and the Mushkin I used ( I thought I had read that the HS wasn't worth the extra $).
Now, bear in mind, even with all of that good hardware going for you, it's still a crap shoot if you will hit a gig with a 700. I personally went through 3 different 700's, and took a small loss on them when re- selling them, until I got a hot one.( many people purchased from Onvia, and a bunch had trouble getting to 933 stable) You may want to spend the extra $ and buy a guaranteed chip.
And yes, I recommend an Alpha. I did the low price- to medium price- to buying an Alpha routine on the HS assby. , and again could have saved some dough just buying the Alpha. ( I personally buy my cooling stuff from Ian at 2cooltek, and have been very happy with his products and fast service)2cooltek

Which Alpha would be better, PEP66 or the PAL35t, or is it a personal thing???

can'y help ya there, as I am a slot-1 kinda guy E-mail Ian, tell him what kinda board and general set- up you are running, and I am sure he will give you a valid suggestion.

alpha pep66 and the fc pal35 performed exactly the same, the difference is that the cusl 2 is a socket 370 board that need the fc pal, but if you get a slot one board, and you use a slotket, get an alpha pep66 because it was made to be used on a slot one to socket 370 convertor. I have an alpha pep66 and have been hoping that the cusl2 I am about to order will be able to fit my pep66 on it

millisec is a good place to buy from too

i have a 700e that had trouble getting past 850 in the beginning but then i burnt in and slapped an alpha pep66 and now i got a ghz

Wuld you guys recommend a PIII 700E or PIII 800e? Seems everyone is going for the PIII 600&700e's and not the 800e. Why is that? Is the 800 bad for oc'ing?

People prefer the 700e's due to their lower multipliers. A 7.0x multiplier leaves plenty of headroom fo FSB overclocking, which is the only to overclock a P3.

For example, my P3 700e runs nicely at a FSB of 143 MHz, resulting in a final clock sped of 1001 MHz. A 8.0x mulitplier would result in a final clock speed of 1144 MHz at a 143 FSB, and you'd be VERY hard pressed to find a CPU that would do that. A 700e at a 143 FSB would kick ass on a 800e at a 125 FSB, even though the final clock speed would be the same. Well, actually, in some things they'd be equal. But for applications dependent on memory bandwidth the 700e will be better.

ya gotta remember that part of the "snap" of an overclocked system is from having a higher than stock front side bus. Basically, all of the 700's to 800's have the same core inside( and I think the 600's as well): Intel "locked" the adjustable timing part of the chip( so retailers couldn't easily sell a 600mhz chip, and tell you it was a 800), so the only way to get these boys to sing is to raise the front side bus. If you overclock a 700 , and the maximum stable fsb is say 142, you are running the chip at 994 mhz. However, starting with an 800 mhz chip(with the same core) you probably will only be able to achieve a fsb of 125 or so, getting you to a gig as well, because that is the limit of that particular core design, but your entire system will not be running as high over spec, resulting in slightly less snap.
