solket sl-66a

Hi there

Really need help on this one!

I'am the owner of a soltek sl-66a motherboard, in it is a PII-233MHz CPU
I Would like to know if somebody know if it's possible to use a celeron 400 or a PIII-450Mhz cpu ???

I have updated with bios version 66a-a2.bin
Think it's the latest one.

I had a look at the specifications of your motherboard.

Unfortunately, it uses the LX chipset, which does not support the 100MHz bus speeds of the later PII and PIII "E" processors. Furthermore, there is no option to increase the bus speed from its default 66MHz, and thus you will not be able to overclock any processors that you may wish to run.

It may be possible to run the 66MHz PPGA Celerons on your board; I'd have to look into the BIOS to see if they are supported. This would mean that you will be able to run up to 533MHz Celerons in your board (the highest PPGA "Mendocino" Celeron). You should also have no problems with running 66MHz versions of the PII in the board, up to and including the PII-333 based on the Klamath core and Deschutes core. Some LX users also report being able to run the later FC-PGA "Coppermine" Celerons based on the 66MHz FSB speed with a BIOS hack that allows coppermine support. However, the chances of this are rather slim.

You will definitely not be able to run 100MHz or 133MHz FSB processors such as the PII-400 or any PIII processor at its full speed.

/edit: I've had a look at the supported CPU microcodes contained within the 66a-a2 BIOS. The outlook is not so good. It contains support for the following CPUIDs:

0632 - the earliest Klamath processors had this stepping
0633 - the C0 stepping of the Klamath processors
0634 - the C1 stepping of the Klamath processors
0650 - the first stepping (dA0) of the Deschutes processors. Only the PII-333 SL2QF and SL2KA had this stepping.

Fortunately, the microcodes are in a standard cpucode.bin format and thus it is possible to add support for more processors, such as the PPGA Celerons or 66MHz Slot1 Deschutes PII processors. Let me know if you are interested in performing this.
