Pentium III 133mhz fsb AND Pentium III 100mhz fsb , What's this a Celeron ?

[Richard_Cranium72]

I've just let myself get ripped off.

Bought a unit "Pentium 3 800mhz"

Oh Boy, I thought.

Get it in and off comes the cover BEFORE I even plug it in and WHAT'S THIS, SOCKET 370 ?

Trying hard not to panic, I run to Intels site and sure enough, **** 100mhz mobo. **** !!

What a rip-off, putting the Honorable name of Pentium 3 on a overgrown Celeron,, I'm disgusted now..

HEY ! Caddman, you tried to tell me,, now I'm ashamed.

I try to do a good job of research before I plunk down the cash, but this one slipped by me.

I was sure the salesman told me that ALL Pentium 3's were 133mhz FSB,

NOT !!!

Cheer up! In a way, you got lucky. The Pentium III Coppermine line started out as 133MHz FSB and Intel marketing realized there were a lot of users who wouldn't get new boards just to buy the chips. So they put out a series to run on 100MHz boards.

They share the 133 architecture and many run at that speed. Yours has an 8x multiplier so it would be a 1066/133 if Intel could guarantee stability. As it turns out, the 0.18u Coppermine cB0 S-stepping craps out around 1050, so don't expect much more than the 1000 the series was designed for. And that will require good cooling and maybe a small voltage boost.

By no means is it an overgrown Celeron, the salesman just didn't know enough about his products. Now you know more than he does! http://sysopt.earthweb.com/forum/smile.gif

Oh yeah. You can't compare a Celeron chip to a P3 Coppermine chip. There are many other diffences between the two:

(1) P3 Coppermine is 100-FSB or 133-FSB, not 66-FSB

(2) P3 Coppermine cache is 256kb, not 128KB

(3) P3 Coppermine cache moves 1/1 speed of the CPU, not 1/2 of the CPU speed.

Well, thanks for the try gentlemen, however this thing is as slow as smoke off of S***

They planned to make 018 micron celerons with 100mhz FSB didn't they ?

So is this NOT what I'm stuck with now ?

Another question, why the Socket 370 deal, was slot 1 dead or what.

One thing I'm gonna try is to remove the HD and install a 7200 rpm unit ATA 66/100 and do a Win98 Lite install and see if that speeds things up any.

This thing is a PIG.

They only had the Slot 1 because of the off-die L2 Cache. The first celerons came slot 1 just because they hadn't made any boards to accomodate the socket based processor yet. I think they made slot based PIII coppermines not only to get rid of older parts, but also to allow those with boards like the asus P3B-F to use the newer core. Anyway, doing it all socket based is more cost effective, and it may even be easier to cool.

Richard,

I'd be happy to take that crappy ol' 800 Mhz P3 off your hands. In fact, I'll trade you my very fast Socket-7 AMD K6-2+ 600 AND mobo for it. http://sysopt.earthweb.com/forum/smile.gif

Seriously, though, if its seeming really slow I'd start checking BIOS settings. Also I'd start trying to OC that sucker. Even getting the FSB up to 110 would boost your speeds nicely.

The chip you received was going to be my next purchase. I have read that it was supposed to be a good chip that would get you close to 1G. when overclocked. The 100mHz is supposed to be better for overclocking than the 133fsb chips. I agree with Dputiger, check your bios settings. I'm guessing that your board also supports an 800mHz processor my Abit tops out at 800mHz.

Fshanda

Let us know how it goes

fshanda ~ A board that "tops out" at some number only does so in terms of what the BIOS has been to recognize in the automatic mode.

When you go manual, it's all FSB and whatever the multiplier happens to be.

DrVette ~ Are you sure it's slow? Have you run a third party utility to check the speed? You can get WCPUID from Mr. H. Oda's site (http://www.h-oda.com) along with SoftFSB and more.

[Dputiger]

Just a thought, Fshanda--

Sometimes a board may seem to have 'topped out' when you no longer have printed settings for it, etc. HOwever, this is often because documentation for the board is not updated on a timely fashion, leading the board to look more dated than it is.

A great example of this is my old Socket-7 IBM system which I thought topped out at 266 Mhz--only to find that I could, in fact, use a 400 Mhz chip in it! IBM simply failed to update their settings correctly.

Furthermore, many board manufacturers will release BIOS settings that increase the max speed a board can support but not update the board specs on their website. I can't say either one of these is true in your case, but its possible.

[Ygor]

As a Tom's Hardware article pointed out some time ago, Celerons are Pentiums that didn't quite pass specs. They are "budget" pentiums.

You might be able to get 1 gig out of it at 125 fsb.

[fshanda]

Thanks for the info. This is why I love coming to this site, I learn something new every day. A year ago I had never even looked inside a computer now I'm building them and doing upgrades for friends. I still have a lot to learn and that's why I keep coming back. I'm about to build one with my 9 year old son. He is going to do all the work and I'm going to sit back and offer advise. He will wind up being a member of this forum shortly.
Please be patient with me I should have this all figured out in about 2 years or so.

I just got my hands on a couple Pentium 800Mhz FSB-100 CPU's today for my workstation! http://sysopt.earthweb.com/forum/smile.gif

From Dual Pentium III 650Mhz @ 733Mhz to Dual Pentium III 800Mhz @ 896Mhz. I would trying take the FSB a bit higher than 112, but I'm not much of an overclocker. I noticed a BIG difference in performance! What used to take me over 2 minutes to open a 541.5mb file in photoshop opens in 45 seconds flat! I also noticed that my SCSI 10,000rpm drive seems to feel faster! All I can say is I'm very happy with the P3 800 FSB-100's! http://sysopt.earthweb.com/forum/smile.gif http://sysopt.earthweb.com/forum/smile.gif http://sysopt.earthweb.com/forum/smile.gif
