MX3231 CPU Upgrade Celeron M to Pentium M

post #1 of 7
Thread Starter 
Hello, first post. Glad to be apart of this forum!

Have a question. Has anyone upgraded their CPU on their MX3231 Gateway Notebook? I'm looking to upgrade to a Pentium M and trying to figure out what's the max I can go. Currently the notebook has the Stock Celeron M 370 1.5Ghz. Ram is PC2 5200.

I have been eye-ing the Pentium M 760 CPU. Will this work? I have been google-ing for weeks and only came up with this... which scares me...

"I bought this lappy knowing it's a cheap machine but I was hoping I could make it half way decent by replacing the 1.5 Celeron M 370 w/400 FSB with a P-M 740 1.73 533 FSB. The chipset is a Via VN800 and it says its compatible up to 533 and 800. When I replaced the Celeron with the P-M, the cpu underclocks to 1.3 with a 400fsb and stuck at a 100 bus speed. The stock ram is DDR2 rated for 533 but it only runs at 266. When I replaced the ram with anything else, the computer will not boot up. Is there any way to force the fsb up to 533? I looked on the via page and I couldn't find anything. I don't know a whole lot about this but I would appreciate any help."

Thanks for the reply!

I notice only my CPU shows C0 stepping, everything else is B1. Does that mean I only a CPU with C0 stepping will be compatible with my system?

C0 stepping is a bit more stable than B1 in the data xfer for usb and S-ATA devices (according to Intel). No performance gain as I understood. In ur case i watch the mfg tech (90 vs 0.13) column difference

motherboard specs say 400 FSB. looks like you are stuck at that speed.

chipset + MB design sets FSB options.

see the Gateway MB spec page

Just a quick update... I bought a Pentium M 735 off of Ebay for $41 and dropped it in. Works without a hitch! Substantial speed increase IMO. Best upgrade! Next time for the 7200 RPM HD! Anyone have any luck putting in 2GB of RAM into this thing?
post #7 of 7
7200rpm is the next best thing, forget about the 2 gigo - u already have 1.5 - too much hassle finding the correct latency (my 2 cents)

cheers ...
