WTB: Pentium III MMC-2 CPU Any speed

#1 Post by kfzhu1229 » Fri Feb 14, 2020 9:35 pm

Hi,
I am looking for any Pentium III MMC-2 CPU to test my Dell Latitude CPx (found locally for free) which does not turn on and I suspect a CPU failure from it (insufficient heat transfer for a 20W PIII-750 chip).
I would want to pay as less as it can be because I have no idea whether I am just wasting my money. Any speed is fine (but preferably not a Celeron variant) as long as I know it is gonna work in that Dell if it were a CPU failure. If anyone who has a spare is in Toronto, Canada it would be even more appreciated for me to save postages.
Thanks a lot!

Found this:
the web wrote:The Thinkpad 600X series came factory with the 650 on models -5FU and -9FU. Those boards also natively support the 850 module. All others came with a 450 or 500 chip and will see both the 650 and 850 at 150Mhz below their original clock since they don't support speedstep. The 770X and 770Z came with MMC slots and could be upgraded to a PIII but I don't remember the limitations. I believe the 770X works better than the 770Z for the upgrade,
Also check with forum user hwattys, he's got loads of oldies.

Okay I have bought an entire Dell Inspiron computer instead to diagnose part by part and waiting to see whether I still need such a CPU. Offers are still welcomed though.

Update: Well turns out the Latitude CPx that I got is CPx J so it supports speedstep. The inspiron I got doesn't. But with the help of the Inspiron, I found out that that 750Mhz PIII CPU is indeed dead, and that the motherboard was dead too. However, when the Inspiron developed the same issue as the Latitude, I found out it was a RAM error (and that these models are known to be flaky with RAM and RAM slots). But with not a single of my PC100 modules working inside the Latitude in either of the slots, with nothing to lose I decided to bake it with 385F of temperature for 8 minutes, and it worked!
So long story short, I indeed need any Pentium III MMC-2 CPU (SpeedStep is also good) so that I don't have to share a single 450Mhz CPU between two computers.
