Yepp, I've done (trying to) an amazing upgrade from 233 MHz to superfast 350 MHz! But my computer doesn't recognize the upgrade and still thinks it got an 233MHz cpu (have done a cpu benchmark with same result)
Got an old ASUS P2L97 mobo, o/s Win98.
Have tried a bios upgrade to ver. 1009 (newest one? I found on ASUS.com) still the same -thinks it's a 233 cpu.

Unfortunately I?ve forgotten most things about older systems, might be something simple I've forgotten about, don?t even know if this mobo (ASUS P2L97) is supposed to be able to handle a PII 350MHz or where to find info about it.
The jumper settings in the manual refer to speeds up to PII 333MHz, 333 runs with multiplier 5.0x at fsb 66MHz but I don?t know how to set up the jumpers for a 350 cpu so I use the 333MHz jumper settings.

Anybody who still remembers how to work these old fashion computers?

Thanks

The ASUS P2L97 features the LX-Chipset from Intel as far as I can remember. This Chipset doesn't support 100MHz front side bus, only 66MHz and then some. So, if you put in a (multiplier-locked) 350MHz P2 which has a 3,5 multiplier... you get 66*3,5 = 233MHz. Sorry pal I guess ya're outta luck except if you overclock your frontside bus to something over 66MHz... :-(

That sounds like something I feared.. and It explains why I get 233 MHz whatever I do.
Hmm, was worth a try anyway, guess I have to look around and see if I have an old mobo stashed away.. a P2B somewhere maybe..

Thanks

I believe that older Klamath Pentium II's are NOT multiplier locked. With half-decent cooling, you can raise its multiplier (3.5x) to something like 4 or maybe ever 4.5x

A Pentium II 350MHz is a Deschutes processor, not a Klamath.

In any case, most Klamath processors produced before August 1998 only allow a DOWNWARDS selection of multiplier, not upwards.
