Are all PIII's Socket 370?

Welp, you have a FSB 100 system, so the real question is whether it's upgradeable to 133. You'll have to do a little research with Compaq on that one.

Yes it is, but it will run at it's locked multiplier at 100MHz so it'll be slower IF the board's max FSB is 100MHz and not 133MHz.

If the mobo only supports 100MHz FSB make sure to get a PIII that is designed to run at 100MHz.
 
...why?

If your mobo supports 133MHz FSB, a 133MHz PIII will run at that FSB. If your mobo only supports 100MHz FSB, that same PIII will run at 100MHz FSB.

All PIIIs based on the Tualatin core are S370. Coppermine PIIIs can be either. If you have a Slot 1 mobo, its not too much of a problem to run S370: just find a SlotKet. However, its impossible (or there is no device to do it) to run Slot 1 CPU in S370 mobo.
 
i think whats trying to be said is that a cpu is multiplier locked, if you get a 933mhz 133FSB cpu and your mobo is only 100FSB, its still stuck at a multi of 7, so you'll have a 700mhz CPU on your hands.

run CPU-Z or something to see what you have on your hands.

I agree..

If it is infact s370 you max speed is 1ghz i believe..

I would assume that chip runs for AT LEAST $100

might as well throw together a cheap AXP or even Celeron D.
 
Well using cpu-z its a coppermine s370 processor

by looking in clock - then multiplier...its of 7 so no luck with new processor? I highly doubt the mobo could run 133 FSB as this a cheapo Compaq OEM motherboard. The chipset is Intel i810e

PIII 1GHz FSB 133 Coppermine is 88 bucks @ newegg

PIII 1.13GHz FSB 133 Tualatin is 49 bucks @ newegg
 
Here is the driver/BIOS download page for your box (I just noticed your rig page has the system's model #)

The i810e chipset can run 133 FSB. See if it is an option in the BIOS, and/or update the BIOS to the one listed on that page, the one dated 11-2001.

...but yeah, why not put together a cheap P4/Celeron/AXP box? P4 based Celeron 1.8 $55 @ Newegg 😉

It's a Compaq which means there is no chance in hell to change FSB. I know, I used to have a Compaq as the main rig. It had the same chipset too.

No, you can get a PIII-S (server chip) at 1.4 ghz, with 512KBytes L2 cache. It runs a bit faster than a 1.6+ ghz Pentium IV.

Also, VIA is still making socket 370 chips (they run at a very low wattage and don't give off much heat; see the via mini-itx EPIA boards).

Finally, I think the PIII mobile chips actually had a socket 479 configuration.

 
100MHz fsb parts and especially slot1 100MHz fsb parts have always held a nice price premium over the 133MHz fsb parts.

why?

simply because there is (or was) tons of people like you looking to upgrade their systems, but could not run the 133MHz fsb, and didnt want to change their motherboards, or cant, because they run a compaq like you or whatever.

also 100MHz fsb p3's are likeable by overclockers as well, who have the capability of running 133MHz fsb, but buy the 100MHz part. an infamous example would be the pIII 700E (100) -> pIII 933EB (133). another example of this would be the celeron(II) 566 (66) -> 850 (100). the main goal of this is to be able to have a faster processor for less, and being less dependant on the motherboard(chipset), ram, and of course throwing the pci/agp bus out of sync (this was before they had pci/agp locks).

your board does not support tualatins, if i was you i would scrap the system, or make a new system if you crave more performance. a p3 700 with 256mb of ram still holds it's own today; it will make a nice email/web computer.

my father runs on a 800EB with 256MB pc133. it serves him just fine for what he needs - email, web, office, music, and a little p2p on the side.

You can't run the Tualatins on the 810e.

You can run 133FSB P3's just fine. The 810e chipset will run the FSB at 133 and the ram at 100. You will likely not need to mess with any BIOS settings at all.

I currently have a Dell with the 810e chipset that has had a P3 1Ghz 133fsb chip dropped in it without a hitch. The FSB is 133 and the ram is running at 100, the fastest you can run it.
 
Thx painman for ur help, but I already have been there...Compaq doesnt give much info about bios updates and it has already been updated like last year.

Im kinda confused now, because you cant change the FSB on Compaq's limited bios like what frustrateduser said

but LTC, what processor speed was the CPu and was it a 100FSB before?

Thx for everyones help, as I will be building an A64 Box, but I kinda want to upgrade the Compaq to the max...just for fun.

Well, maybe I should put a disclaimer here. I had (still have) a Presario 5474 with a Celeron 500 and the i810E-DC100 chipset and there were no way to change it. Even stuff you normally found in BIOS weren't there. Your machine is newer and they might have changed it.

I'd say just scrap the rig and take the useable parts and build a new one. Some time ago I speced a Case+PSU, Mobo+CPU and RAM from outpost and it would cost $142. :Q :thumbsup:

edit:

Found my old thread. Super cheap system.
 
You can't change the FSB manually. It will automatically change just like the multiplier will with the new CPU. I have had both 100 and 133 chips in the Dell and never had to change anything to get them to run properly. Most Intel chipsets work this way. You don't need to do anything unless you intend to run the chip or memory out of spec. As long as the chipset supports the CPU, it is automatically recognized and the board sets itself up for it.

In fact, most chipsets from all mfgs work this way. You only need to change a setting to overclock, or to use a chip that the board doesn't recognize.
