Can I upgrade my CPU

[quintoc]

Hello,

We happen to have an old Compaq Presario 5528 All-in-one that we are wanting to use for our Preschooler, but a lot of the software we want to get needs a faster CPU than it has.

It has a 75 MHz Intel A80502-75, SX998 CPU, and I am wondering if it is possible to upgrade this at all with any current chips, or if it is possible to find any older chips still that would be compatible. I need to get up to at least 233 MHz for some of the software we want to run.

Thank you for any assistance,

Kevin Allen

hello

i'm sorry but i've got bad news for you... your chances of upgrading that computer with a recent chip are very remote (bios compatibility issue + voltage and multiplier limitations) .you might be able to install a pentium 133MHz, but i don't think you can put any faster cpus :'(

I Agree with LKG01A and I think in these Compaq were Sockets 5 so max will be 133 MHz. If there is Socket 7 you can propably plug max CPU 200 or 233 MHz MMX.

Good luck in upgrading old PCs

Thanks for the sobering news - I actually didn't have much hope that it would be possible.

Regarding the issue of Socket 5 vs. Socket 7 - how would I find that out?

Also, if it is Socket 7, where would I be able to get a CPU 200 or 233 MHz MMX?

Thanks again,
Kevin

well to find out what socket your motherboard has, you will have to open your PC case and find the cpu (you should find a heatsink with a fan on top) under all that is your motherboard cpu's socket it will be marked "SOCKET 5" or "SOCKET 7". To get a another cpu, i would sugest you ask for one in the "For Sale/Trade" section of the forum...

and i seriously doubt a pentium MMX is compatible with your compaq computer (MMX cpus require dual voltage and old motherboards do not have dual voltage)

Thanks for all the feedback - I wanted to make sure I understand, though.

I did check, and it does say Socket 7 - I also looked up Socket 7 on this site and there is a list of compatible processors - is there any reason that any of the listed processors would not be compatible in my situation?

Your help is very much appreciated,
Kevin

Dont give up hope.
Thank the CPU gods for Overdrive CPUs
with an Overdrive you can easily have a 180 or 200MHz MMX machine out of that.

He can use Overdrives but one piece cost same as full PC based on Pentium II 233 MMH
