My current system configuration is pretty crappy by today's standards, but what can ya do. I have Asus P2B MoBo with a Celeron 533. This bites. I just recieved a P3 I'd like to use - but no matter what I do - I can't get it to work. Is it an unusable combination? If so - which part do I have to replace?

Asus P2B Rev1.10 Bios 1014R3 Slot 1 (I'm not sure the max FSB - 4 jumpers go up to 133 - research so far led me to believe that means its capable of handling 133MHz FSB)
Asus S370-L Slotket
Intel Pentium III 866MHz 133FSB 256KB L2 (CuMine, FCPGA)
2 x 128MB PC133 SDRAM
1 x 256MB PC100 SDRAM (if this cant take 133, should I back off the FSB, or not use this?)
3DFuzion GeForce MX4000 128MB AGP4x (think its running at 2x..)

So far, I've flashed the bios, tried the FSB at both 133 settings, 100, and 66Mhz. I don't know what else to try? Any ideas would be greatly appreciated. Could it be I just recieved a bum processor? It didnt work on the same config in an Asus P2Z Rev1.12 Bios1013 either...

.. clear CMOS with new cpu?
.. Slotket can't handle 133?
.. volt-mod slotket?

I just did a quick search on the asus sight, according to them , they
added support for the coppermine cpu 2 bios updates before the last
release available.
Version 1012 2002/08/05update

OS All

Description P2B BIOS 1012
Added microcode update support for Coppermine B-0 stepping.
Does the card your using for the socket to slot conversion support the
P3/coppermine cpu, if so then I'd be thinking it was given to you being
it was no good.

well .. its tough to find information about my specific slotket ... it seems the Asus S370-133 would guarantee it working, but one site did mention my exact adapter as verified. Another thing .. is it seems most cases where a PIII is slotket-ed into a P2B, the person was using a 100FSB CuMine. One site did say flat-out that if you're using a BX based board (440bx chipset), you can't run 133FSB CuMine. Could that be just the voltage issue? But then again, I suppose it would run at 100Mhz.

Also, I wonder is having Bios 1014 over 1012 might be bad. Could that be? I know it's more up-to-date, but I'm not using a Tualatin ..?

It'd be kinda crappy if this cpu didnt work x.x i paid 20 bucks for it on eBay.

Iv'e personally never seen bx chipset boards run more than 100mhz fsb
but iv'e not had too many asus boards either,, they probably have run
them at 133mhz, from memory they engineer thier own bios's...

& seeing that the bios update I mentioned above mentions they added
support for the B-0 stepping cpu, a quick check on the intel sight for
stepping specifications clearly shows they run 133mhz fsb, I copied &
pasted the B-0 stepping cpu's below, so perhaps the cpu is dead, you'd
have to confirm that in another board of course..

see for yourself

Asus officially added full coppermine support with Rev 1.12, older boards down to 1.10 may have a voltage regulator going below the minimum 1.8V VCore of the older boards or not. If you CPU does not work try to jumper Slocket to 1.8V. I have an antique 1.05. running fine with a 900 MHz Coppermine in this way.

The latest Bios supports all Coppermines, maybe even Tualatins.

Well here's the specs# and info of my exact chip it's actually cC0 stepping, if that makes a difference.

SL4CB 866.00 MHz 133 MHz 0.18 micron cC0 256 KB 370 pin

I dont know ... I hope it's not the proc ... but thats what everything is pointing to so far...

- Also, I've tried setting the jumpers on the slotket to default AND 1.8v .. nothing works. Is there a chance it could be that the two just don't want to work together? Or is it that the cpu is probably fried?

Couple more questions - should I try the slotket voltmod? Where is the clear CMOS jumper on a P2B? I also have a P2Z board that has a jumper for setting the VCore to "normal" or "test". Would that do anything?

Probably there are two small solder points to bridge or just remove the battery and bridge the contacts there (system has to be powerless).

Make sure you test with 100 MHz FSB, the P2B might have problems runing at 133 MHz. Set 100 MHz FSB on the Slocket, too. You may need to set your slocket from auto voltage/FSB detect to manual settings, check slocket manual.

Does the CPU get quickly very hot or does it stay warm or even cool ?

Well, I removed the battery and stuck a jumper on the any open connections that were just two pins ... then reassembled everything, put er on 100Mhz .. still nothing. I popped in a Pentium II 400 and cranked the FSB to 115MHz - and that's what I'm using right now. =\ I suppose it's a bum cpu. I think the only way I'll really know is trying it on another mobo. My second test bed is almost identical to my primary - just an Asus P2Z instead .. and the third board was questionable to begin with - it didn't boot with a known working cpu 2 out of 3 times. *sigh*

fried CPU or Slocket, or this slocket is not suitable for FC-PGA (older revision maybe, PPGA-only)

well the slotket is Asus S370L Rev 1.00. I think it's probable that it doesn't support it somehow. Being CuMine, or voltage problems .. whatever. Instead of springing for a new slotket, I'll just buy a new S370 board .. one of the shops in town here has a socket 370 board with an AGP slot that he'll sell me for $25. Probably best in the long run anyway - I'll all but given up on using that Pentium III with my P2B or P2Z.

Note - I've swapped my Celly 533 for a Pentium II 400 o.c @ 533. 512kb L2 vs 128kb ... but half speed .. hmmm ... also the P2 has a native FSB of 100MHz .. in my opinion, making a better choice. The fact that the Celly can't seem to go past 66MHz FSB might have something to do with this (could my slotket be celeron compatible only - therefore the tualeron mod is necessary?). My slotket also says PGA370, not FC-PGA or FCPGA2.

Have you tried 75fsb on the celeron.
iv'e ran the celerons at 75mhz fsb no probs on boards that give the
option, very rarely have I found them to run at 83fsb though..

There's a S370 manual, please check JP6 is set to Coppermine and not to Celeron (probably meaning PPGA)

just reread..as far as i can get it right now you have a slot1->s370 adapter with a celeron 533 working (celeron with a big metal heatspreader aka ppga). you bought a p3 (small blue die, no heatspreader aka fcpga), plugged it in and it didn't boot. right?
IF so..you have to mod your slot1->s370 adapter.
according to this. tualatin mod basically does the same with some additional modifications.
if you want to do the quick&dirty mod just follow this link. btw. after this mod your Piii should work flawlessly, too. and if the pll on the mainboard supports 133/33 there is a good chance that the BX will work with 133MHz. happy modding :)

According to the manual both PPGA and FCPGA are fully supported, you just need to set jumper 6 to the correct position to switch between the two types.

oops, yes, Denniss is right. i must have missed something while quickly watching over it..
