Upgrade cpu on A31??

[SaberX]

I have did some serching on the forum and seems like just the A31P's and take the cpu upto 2.6Ghz.
Is this correct?
I have an A31 with P-4 M 1.6ghz ,16meg ATI 7500 video.
Will the motherboard in my system handle the bigger cpu's?Say a 2.4Ghz.??

Yes, it will.
As long as the CPU is compatible with the motherboard, you won't have any problems.
I installed a 2ghz P4M on my A31.
It runs fine.

Any of these processors will work:

Mobile Intel® Pentium® 4 Processor-M (400 Mhz bus speed)

2.2 GHz: SL6VB, SL6LR, SL6J5
2.4 GHz: SL6K5, SL6LS, SL6VC
2.5 GHz: SL6P2, SL6WY
2.6 GHz: SL6WZ

Thanks for the info.
I guess i got to start looking on e-bay for one of those cpu's.

WOW
I just looked on e-bay.
The cheapest 2.5 i seen was at $140.00 and still going.A few there with buy it now price of $230.00.
The 2.6 will be over $300.00 with shipping.
Looks like i'll be keeping my P-4M 1.6 for a while.

Having purchased an A31 two weeks ago and opening it up last weekend, I'm interested in upgrading the 1.6Ghz CPU (if I can fix an intermittent video memory bug). How bad is the extra heat being thrown off the faster CPUs? Or did Intel switch design rules (i.e., shrink the part) and thereby reduce or maintain the same power consumption?

The fan in my A31P handles the heat from the 2.6GHz cpu just fine.

People on E-Bay seem to bid up the prices for the SL6WZ (2.6) processor to about double what the 2.4's go for. I watched for about three weeks while the SL6WZ's went as high as $200, while the SL6K5's languished without interest at $99. I thought that the extra $100 for 0.2 Ghz was a little steep, so I settled on the 2.4's.

If you search for posts under my name then you'll find some info on this. If I was to do it again on an A31 (no longer have them) then I would go for the 2.4 Ghz max. The 2.6 did in the end cook my machine. (had for a while a 2.2 in it too).

Before you do anything make sure to get the IAA (Intel Application Accelerator - free on Intel's website), it seems that on the later CPU's it enables some form of hyperthreading: an import of a 150M row database used to take around half an hour and after installing the IAA it took just 4 and a half minutes!

Just finished upgrading a Z61m from a 1.83 Ghz duo core to a 2 Ghz core 2 duo. (The A31 upgrade went far smoother) This will be the info for a later story once I have collected enough information on how it runs in real life. (Basically I am under the impression that I have a data I/O bottleneck into the CPU, not so much the pure CPU computing power but shoving the data in and out of the CPU. HDD performance is very satisfactory and not the cause of the bottleneck, hence the upgrade to a CPU with 4Mb L2 cache)
