To determine part numbers for the Shuttle AV40S (V1.0) motherboard, we use best guess approach based on CPU model, frequency and features. In some cases our guess may be incorrect. Please use specifications from the compatibility list to confirm processor's part number before ordering.
2.8GHZ CPU
This list does not show the Northwood 2.8GHZ CPU sSpec SL7EY which I have installed on an AV40S V1.0 with BIOS AV40SA08 and it works perfectly. The SL7EY is, I believe, the fastest Pentium 4 with a 400FSB available.
