CPU upgrade
(Click here to view the original thread with full colors/images)
Posted by: jimt
I would like to upgrade the cpu on my presario 7598 from P3 600 to 933 or above. Uses socket 370.
1. Will there be a noticable improvement in speed?
2. Will Bios or other things need to be changed?
3. Is it simply a matter of unplugging one and plugging the other in?
4. Where can I find step by step help?
Here is a link to the specs: [url=http://h20015.www2.hp.com/hub_search/document.jhtml?lc=en&docName=c00034150]
 Thanks

I assume you are new to this, so I will try to be as clear as possible.
1. The speed of your computer depends on many factors including software and hardware. I had a P3 1GHz processor on a cheap motherboard with a lot of really crappy ram. It was slow. Upgrading your CPU will only give you a signifigant performance increase only if the rest of yor system isn't dragging you down.
2. I really am not one to answer this, as I have never switched CPUs out of a motherboard, but I would think that the BIOS could detect the change. (I mean, it detects it when you first start up, doesn't it?)
3. Yes.
4: Here:
A: Get everything in one place: Computer, screwdriver(s), screw cups/egg carton, new CPU, and thermal paste. (I recomend paste over tape.)
B: Disconnect all power. You do not want to cook yourself; stay rare, very rare.
C: (optional, but suggested) The Motherboard should be mounted on some sort of tray or backing or something. Remove it if possible to improve access to your motherboard.
D: Unplug CPU fan from motherboard. (This should be a big ol' fan and heatsink sticking up from the motherboard in the upper half near the LPT/Printer port)
E: CAREFULLY unclip fan and heatsink from your cpu socket. The piece of plastic that the clip holds on to is fairly small ( -- <-about that big), do not break it off or you will have to buy a new motherboard.
F: Pull lever out (to get it past the catch) and up to about 90-100 degrees from the motherboard. Gently lift CPU from socket and place on static-safe surface (foam, mylar bag, etc.). Drop (DO NOT PUSH!!!) new CPU into socket in the same direction as the old (gold corner ought to point towards the base of the lever. If it doesn't go in, tell us; don't force it. Push the lever down to lock the CPU into place.
G: Wipe the bottom of the heatsink clean or remove thermal tape.
H: Put thermal paste on CPU die (that little black thing in the middle) or put thermal tape on heatsink where it will contact die.
I: Clip on fan and heatsink. (This may not be easy, but you probably don't need to worry about breaking the tabs.) Plug fan back into motherboard.
J: Reassemble. Motherboard tray goes in the case, the case gets covered, and plugs go back in.
K: Cross your fingers and boot up.
