HEllo,

I have been searching the forum and google but can not find the answer..
Bought this pc at a yard sale for a few dollars and wanted to beef it up....What is the fastest CPU I can get?

Compaq Presario 5000US

current CPU: AMD Duron 750Mhz

motherbord Serial: 0107518074

That is a socket A motherboard, it is VERY old. Try HP-Compaq website for info. That CPU is on a 100 MHz FSB, Unless it can run at 133 you will be very limited on upgrade. Even at 133 you would be lucky to reach 1800 MHZ, and a secondhand CPU woul be expensive. What is present spec, and what do you want to do that it can't do now? What version of Windows?

Mike.

Compaq presario 5000US
Windows XP Home

Ram: 384 Mb
HDD: 30 Gb


I'm wanting it to quit crawling. basicly max out its cap... Just for kicks mainly although its a nice secondary PC to do little things on..I have emailed tech support at Compaqs website, but haven't received a reply yet..

Not knowing specifics about the board, it's hard to say exactly what it'll support. Even if you could only get up to one of the older Athlon XP's, the 2100+, you'd still more than double your speed.

You should also really consider upgrading your RAM. Even going from 384MB to 512 would give XP a lot more headroom, and a full gig has potential to help more than a small processor upgrade. The Duron isn't that great, but realistically, your lack of RAM is probably hurting you more for performance.

lol...that board is pc100 sdram..and max you can put is 768 MB.

id say dump it....more memory alone would cost you 80$

You can buy a new 256mb stick of ECC pc100 for $15.50 right cheer ....

Here is an AMD MOBILE XP-M 2200 socketA for $29 shipped ...

If it will boot you can overclock the snot out of it - lol - you might hit 2GHz!

I think it would be worth a shot in finding a low-wattage AMD Geode NX with a 100mhz fsb and seeing if it will work. They are s462. Might be be able to run it without a fan and heatsink

mon - dmoz and colonelblake are right. Ignore wisecracker's post -- the RAM he links is *registered* and so won't work in your system, and the CPU almost certainly won't be supported by your BIOS.

Compaq support finally got back to me and said You can upgrade 1400 MHz AMD Athlon processor for the computer. 1400 MHz AMD Athlon is a processor tested on the motherboard bundled with the PC.

and they gave me the system specs

So I guess I can go for a
AMD Athlon 1.4Ghz 200Mhz FSB CPU?

Plus for these old parts I don't really buy the stuff, people give me all the old spare parts and I also find them in the trash or yard sales...

Yeah montauk, that'd definitely be faster, and if you consider upgrading the RAM as well you'd have a pretty decent internet machine.

Doubling the CPU speed is always nice. If you haven't yet, try installing Ubuntu 8.04 (free!) on it. Ubuntu and other Linux versions often run faster on a system than does Windows.

Running Ubuntu will make the computer seem brand new...

The Athlon 1.4GHz is 100MHz 'double-pumped'. I believe your mobo may be a Via KT100/133 chipset OEM FIC provided to Compaq.

Check out this link for the FIC AZ31 manual and compare it to your mobo:

The Via KT100/133 has ECC memory support.

Yes, but it does NOT support *registered* memory, so your linked-to *registered* RAM won't work.

In general, consumer motherboards support only unbuffered RAM, while server motherboards support only registered or fully-buffered RAM. Each type of motherboard, depending on the specific model, may support ECC and/or non-ECC RAM. However, almost all unbuffered RAM sold is non-ECC, and most registered/fully-buffered RAM sold is ECC.
