Derating a PII400, please help.

[shulland]

I'm posting in this area because it looks like you all helped the PB guy in a timely manner with some great advice. I have a question and was wondering if any of you could help? I have a ASUS P2L97 motherboard with a 233 PII (non cleron) and thought I'd add a PII 400. Problem is the MB only goes to 83 MHz (66,75, and 83) on the bus freq. The freq mult. settings are 2, 3.5, 4.0, 4.5, and 5. Can I drop the 400 in and set the bus freq to say 83 and the mult to 4.5,or can I go say 83 and 5? The other option is overclocking the 233? Have you all seen another place I could post this message for help? Thanks Hoakey

maybe there is a bios upgrade for the mobo

I would be less worried about the FSB freq of the MB as to the voltage regulator of the MB. If it is designed for the older P2, then it uses 2.8v for the CPU core, which is normal for the old 66Mhz units (except for the 333). The 400 requires only 2.0v and 2.8v will burn it up quickly...

Not a recommended thing to do!
