AMD Socket A HSF w/ Socket370 Celeron

[mujahid7ia]

Hi

I FINALLY found jumper settings for the FSB, multiplier, and VCORE for my damned Compaq. I'm planning to O/C from 566/66 to fsb 75 or maybe even 100.
I don't think the hsf that came w/ the compaw is up to snuff, So i though i mite use the stock hsf that came with my athlon2500+.
Can I do this? Will it clip on right?

Should do just fine assuming that there is sufficient clearence around the CPU socket to accomodate the H/S. The clip and heatsink base should be designed to work on Socket A or Socket 370.

OK, Thanks Ripper2860, I'll be gone O/C-ing my Celeron566 to ~637 (for now w/ 77 FSB, then i'll see stability for 850 w/ 100fsb)

Has the heatsink been used before? With a pad?
As long as it hasn't been used or it has but with paste you are fine.
Otherwise you would be putting a lot of work into clean the pad out of the pits on the heatsink (GL!) or risk overheating.

There wasn't sufficient clearence, some capacitators were blocking the socket. The one that came w/ the celeron really sucked!!

Also on the mobo it had the white writing for jp 3, 4 ,5 but i couldn find those jumpers anywhere (for FSB) !!!

How about this ...

On the Celeron H/S do the following ...

1. Remove the thermal pad with Acetone (finger nail polish remover w/ Acetone, Carburator Cleaner or "Goof-Off" adhesive remover will work, as well) and clean off residual solvent with Isoprppyl Alcohol.

2. Apply some good thermal compound to the H/S and CPU core

** The above should shave a few degrees off !

3. OPTIONAL -- Remove the stock FAN from the CPU (should clip off) and replace with a higher speed 60MM fan. Short self-tapping sheet metal screws should work, as long as they are thick enough to wedge between the fins. I've also use platic molly screw inserts betwen H/S fins where screws were to thin. yuo may need to turn the FAN diagnally in order to properly affix it to the H/S.

Thanks for the advice. Instead of acetone, can you also use alcohol swabs/pads (70% pure isopropyl alcohol) to remove the thermal pad? (Just wondering)

I have some AS Cermanique lying around, maybe I'll use that.

Too bad I can't O/C though, i hear the Celeron 566 has a lot of potential for 100FSB to go to 850mhz.

Is it strange that the chart for FSB speeds and jumpers is silkscreened on the motherboard and I can't find the jumpers anyhwere (relatively small mobo) ??!!?!?!

You can try the Alcohol, but you really need a solvent to dissolve the pad residue. Anything that you use to remove decal or sticker residue will work.

Compaq mobo's are not O/C freindly. Even if you could change the FSB, there is no way to change the VCore to the CPU. I have a Slot-1 CPQ DP-350 in which I have PPGA Celeron 366 running on a SLOTKET at 550MHz 100MHz FSB). The FSB can be selected via the SLOTKET, but only to the extent that the clock chip on the mobo will let it be. The great thing is w/ most Dlotekts, you can also set the VCore.

** Your mobo is probably a Socket 370 and not a Slot-1, so a Slotket is a non-option.

Ex: The sloteket supports 133MHz FSB, but the mobo does not, so even if the chip could run at 133MHz FSB -- it cannot be set.

Most CPQ mobo's I've seen do not use jumnpers for FSB, but instead use DIP switches. Most depend on reading the CPUID at power on to set the FSB at then MFG spec's. Compaq typically designs and MFG's their mobo's, but in the home line, they use OEMs. They do typically ask the OEM to remove any O/C functions such as FSB jumpers, VCore settings, etc.

** My mobo had dipswitches, but vewn after setting them to 100MHz, it would still default to 66MHz after powering up and reading the CPUID. The Slotket tricks the mobo by retuning a CPUID consistent with a 100MHz CPU., fortunately.

I don't expect that you will be able to O/C -- Unless ...

If you feel daring -- You can do a search on Google and see how to use thin wire to join several pins on the back of the CPU and have the CPU report to the mobo as a 100MHz CPU. I know this can be done and is reversible. There should also be a way to adjust VCore the same way !!

Well, this PC is hardly worth anything now, maybe i'll try it
I'm building my new computer anywayz..

Well, thanks for all the help.
