BIOS and REV (revision) fields list the minimum required releases. All newer releases & revisions are acceptable unless otherwise noted. The revision number of your motherboard is written in white silk screened letters in the upper left hand corner of your motherboard, just behind the leftmost ISA/PCI slot. Example REV 0.2 If your desired processor is not listed or recommended please wait for further updates to this list as we test newer processors. * - Classic Athlon processors recommended whenever possible. For processors with newer performance enhancing cache (a.k.a. Thunderbird) see EPoX knowledge base article #1268 for more information.

Intel Socket 370 Recommended Processors List Notes: Unless otherwise noted all the above models can support single Intel Celeron processor in PPGA packaging at 333 to 500MHz. BIOS and REV (revision) fields list the minimum required releases. All newer releases & revisions are acceptable unless otherwise noted. Above find a list of models and their corresponding revision (REV) numbers requirements for the selected processors. Sorry if you do not have the required REV # or higher you should not use the listed processor. The revision number of your motherboard is written in white silk screened letters in the upper left hand corner of your motherboard, just behind the leftmost ISA/PCI slot. Example REV 0.2 If your desired processor is not listed or recommended please wait for further updates to this list as we test newer processors. Jumper settings: If your motherboard does not have jumper/DIP settings for a particular processor recommended above simply set for any speed processor (example 550MHz). Intel processors are multiplier locked and will ignore most motherboard settings. Ensure that CPU voltage controls if present on motherboard are set for AUTO unless otherwise noted in your manual. For additional help email support@epox.com
Intel Pentium III Processor notes: E = Processor with "Advanced Transfer Cache" (CPUID 068xh and greater). B = 133MHz F.S.B. where both bus frequencies are available for a given core frequency. FC-PGA Celerons and FC-PGA Pentium III processors are listed on page 4 by their actual Intel processor name (model); not their frequency.
- Minimum support offered for Intel Celeron processor in PPGA packaging at 333 to 500MHz.
- EP-D3VA notice: Dual Celeron processors are not supported. Not all Pentium III FC-PGA processors support Dual processors. Check processor documentation or Intel datasheets for more information. The majority of dual processor capable operating systems are designed with the expectation that all processors in the multiprocessor system are of the same stepping and use the same processor-specific patches. When using multiple processors of different steppings unexpected stability issues may occur; such as system lockups, blue error screens and boot failures. The solution is to obtain processors using the same steppings. Microsoft Windows NT/2000 users can use the Administrative Tool named `Windows NT Diagnostics` to obtain the processor model and stepping information. - Intel retail heatsink not recommended do to space considerations. OEM heatsink solutions are suggested (60mm x 60mm).
