I have an AMD Athlon 500 Mhz processor in my Presario 5838. I would like to upgrade it to the highest possible frequency.

The problem is I don't know what to buy because there are two types of processors: one with an L2 Cache of 256 Kb and one with 512 Kb. I want to know whether these will work in my computer.

Specs for my Computer - http://h10025.www1.hp.com/ewfrf/wc/document?dlc=en&lc=en&product=93633&cc=us&docname=c00034102

Processor 1 that I am Considering - http://www.icreseller.com/detail.aspx?ID=1386

Processor 2 that I am Considering - http://www.icreseller.com/detail.aspx?ID=1377

I just want to know whether either will work in my computer or which one will and which one won't.

If you look at the specs from the link you posted it sais this under the CPU section "Processor Speed - (MHz) 500/550/600" and "L2 Pipeline Burst Cache 512 KB Integrated"

Those may run at 600 mhz or not at all, they may get rejected by the motherboard as unrecognized.

Have a Compaq Presario 5610 that I upgraded successfully. I'll list the key items that allowed my upgrades:

My mobo uses jumpers for the CPU speed and there is a diagram inside the case that details this.

My max is 500Mhz on this machine, so I found a PIII 500 to replace the PII 350.
Installed the PIII but L2 cache was not recognized!
Discovered that Compaq offered a BIOS update for the 5610.
Flashed (upgraded) BIOS and now my L2 cache was recognized!

And lo and behold my max memory went from 3x128 to 3x256!
In reality it seems that the machine won't cache more than 512MB but no matter, I'm running 2x256 which is great with XP.
I believe it was Sandra Lite from SiSoft that told me that memory capacity had increased.

So check for a jumper scheme and don't buy any memory until you upgrade BIOS....I wasted money on (3) 128MB sticks!

JF

I would go with the larger L2 cache, indicative of a more advanced processor core.

It's a SLOT A mainboard...

AMD does not make slot A or socket A processors anymore, what you'll find now is what is left of the socket A processors and none of those will work in your compaq...


You could pick up a new Compaq at Walmart for 1/5 the price of the top Slot A processor, and that processor will be used as opposed to a NEW machine...

I understand what you are all saying...

Right in the

Here is another link that I found while doing research...

Presario Upgrades

Check the post by Gary Heck In that post, it says I can go up to 1 Ghz

Here's another link that I found...

AMD Processor Upgrades

That has a "recipe" for all AMD processor upgrades (not the newer ones though). It says I can go to 1Ghz as well. "Processor 1" is a 1 Ghz thunderbird just like HP forum guy says.

But those prices are only 40 or 50 bucks. I doubt very much there is a computer for $10 (except on ebay) lol.


The basic information I want to know is whether to trust these people and their upgrade information.
