I need quick info about CPU speed please....

[glendor]

What system would make a faster Win2K server...

Abit BP6 with DUEL PII 266mhz processors

or

Abit BP6 with DUEL Celeron 366mhz processors OCed to 550mhz

or

Asus P3B-F with A SINGLE PIII 600mhz processor


I'm planning to run it as a Windows Terminal Server for two terminals, and maybe as an exchange server.

The two celerons will flaw the P2's.

Hmmm... so it's between the P3 and the cellys..... Dunno 2B honest! I reckon the cellys, but that's that's entirely subjective http://sysopt.earthweb.com/forum/smile.gif

Is that an 'E' P3, or the Katmai? If it's an E, then it's good for 800MHz+

[glendor]

According to CPUtest:
Slot1 Intel Pentium III E
Model: 8 - Pentium III E 256k L2 Cache
Stepping: 3
Codename: Copermine (0.18 micron)

What is significant about the stepping? I've heard this term thrown around a little bit, but haven't figured out what it means yet. What kind of OCing should I expect out of the CPU. Right now it is under-clocked at about 558mhz because I can't get it to 133mhz clock speed. I think it could be my Micron PC100 RAM holding me back, but I'm not sure.

If anybody has time to give me some pointers that would apply to my Asus P3B-F / P3 600E / PC100 situation, I'm all ears...

If it is a server you need, you'll be better off with the dual setup (eventhoug the single P3has double the L2).

It may work a biot slower as such but it will have a lot of headroom. Where the single P3 will be asked to do too many things at once (and slow down, but this is not my point here) the dual setup will have one more CPU to load.

This is very simplistic, and if you are not convienced just look at other servers and you will notice most are multi-CPU.

Btw, what kind of server will it be (to run W2K)?

[krusty the klown]

Well, that's the right chip for OCing!

I think the steppings are to do with subtle revisions made by Inhel - I dunno whhat the 'good' steppings are!

You may have to up the CPU core volts a bit to get 133FSB ~10% should be a safe max (default is 1.65, so ~1.85V max - some people go higher, but usually have to use decent cooling).

I agree, your mem is likely to be holding you back, but you could try dropping from CAS2 to CAS3 and slower timings.

Also, bear in mind that if your board is a BX, at 133FSB, your AGP clock is well over spec (89MHz) - this can also hinder OCing on a BX board.

Even so, you should be able to run ~120MHz FSB with the PC100 ram - I've had generic PC100 @ 133 with CAS3/normal timings.

See if you can borrow some PC133 from a m8!

The chip should be good for 800MHz, but may take a voltage increase to get there....

Try some 133 mem first, then, if that doesn't work, try putting an old PCI graphics card in, just to see if it's the AGP card holding you back - he says: assuming that you have an AGP graphics card http://sysopt.earthweb.com/forum/wink.gif

Remember to (if there is a manual control to do this) set the PCI divider to 1/4 * FSB clock when running at 133MHz FSB. This may be done automatically by your mobo, or it may not!

Thanks to everybody for the input. I'll try to answer a few of the question you've asked...

Otheos - Yes, I'm setting up a Win2K server with plans of running Windows Terminal Server.

My two 128meg Micron PC100 DIMMs seem to work well up to 124mhz, but since the mobo reports the clock multiplier for this chip at 4.5x, and won't let me change that, it limits the speed I can run at 558mhz. Even if I had RAM that would run at 140mhz, how would I get above the 630mhz limit?

Is there a way to override what the CPU reports as the maximum clock multiplier?

[krusty the klown]

If it's a 600E (not EB), then it will have a multiplier of 6X. Set the multiplier on the mobo to 6X and if you run the FSB @ 124MHz, you will find the chip clocking at 744MHz!

The multiplier is locked on that chip and there's B.all you can do about it....

[glendor]

Krusty, you seem to have all my answers :-)

What if it is an EB? When I ran CPUtest, it reported:
Slot1 Intel Pentium III E
Model: 8 - Pentium III E 256k L2 Cache
Stepping: 3
Codename: Copermine (0.18 micron)

What is the difference between the E and the B and EB?

Please let me know, and thanks in advance for your help.

[krusty the klown]

Eh Up!

The EB flavour is supposed to run @ 133MHz FSB and the E's are supposed to run @ 100MHz.

Because the multiplier is locked, the OCers choice is the 'E'

For example, I have a coppermine 550E (5.5*100) running at 825 (150MHz FSB). Now, if I'd bought a 533EB (4*133), I would have needed to run a 206MHz FSB to get 825MHz!!!!!! I don't think so!

There is also a 600B - this is based on the old 0.25micron Katmai core, but will achieve little more 'cos ~ 600MHz is the limit for 0.25mu cores.

You have the good OCing chip - I hope we can get you to the 800MHz mark http://sysopt.earthweb.com/forum/smile.gif

BTW: if I set my multiplier to anything other than 5.5*, my BIOS says that the chip will clock at FSB*multiplier, but the chip ALWAYS POST'S at FSB*5.5. To see what speed your chip is actually running at, either catch the info on the initial CPU&mem detection in BIOS, or, if the BIOS doesn't show the info, try downloading a util called WCPUCLK from:
