Can Anyone Identify This Amd Cpu?

[filbert]

I've fitted a HSF to a naked 64 chip, it went ok, but you must use the bolt on method not the clip-on type.
This is a Mobile Athlon xp-m socket 754 chip, not a sempron

I normally use the clip on heatsinks with my heatspreaderless A64s. I just have to take a dremel to the mounting bracket first.

Hi OP,

I found this quite interesting ...

Nearly all A64 motherbaords will shut off the instant the on die temps hit 94C. This takes about a quarter second with no heatsink contact (ive done it). The chip will normally be fine though (mine survived 6 tries before I finanly realized what the hell I was doing and stoped).

I felt it was time to upgrade my M-XP 2000/A7N8X-D combo for their 64 bit equivalent.

I eBayed an s754 mobile64 3000 (AMN3000BIXSAR) and, in a separate transaction, a Gigabtye K8NS Pro motherboard. When they arrived I stopped off at the local computer shop and bought an Asaka AK-860 HSF. I swapped out the old bits and installed the new without a hitch. I confidently covered my ears to protect them against the bang and then pressed the power switch. I was greeted with the sound of fans but no beep or video BIOS display.

When I took off the HSF the Artic Silver was still in a virginal state. I thought that I had 2 separate problems but from your post it looks like it might just be the one. Is what happened to you? If it was I would appreciate recommendations, from anyone, for a nice (cheap) bolt-on HSF for an s754 motherboard?

Thanks.

When you turn on most A64s with no/inadiquate heatsink contact, the fans should spin up, and the power light come on, for a fraction of a second then the whole system should shut down.

All the bolt on heatsinks tend to be rather good/expensive. Most anyone will do, but do not use overly heavy ones (anything over 600 grams or so is not a good idea), as the surface area of the die is usually too small to prevent the thing from sliding all over the place and ruining the thermal interface material. It may alos be easier to damage the die with a very heavy heatsink. Most screw/bolt on heatsinks are not cheap, as they are of high quality. The only bolt on heatsink I have used so far with bare die A64s is the swiftech MCX64-V, wich worked very well, though it is on the heavy side.

You can sand the feet off the standard mounting bracket (leaving about 1.5-2mm on each one), and then cut notches in other parts of the bracket where motherboard componentes would otherwise come into contact with it. the you can use a notmal clip on hatsink.

With bare die CPUs I strongly recommend that you use a heatsink with a copper base, or one that is well lapped (aluminum or copper). If you use a rough alluminum based heatsink on a bare die A64 the CPU will run much hotter than it should, esp if you use above stock voltage/overclock, as the heat will have trouble getting to the hatsink to be disipated.

This is what I have seen:

Rough/average aluminum base = higher temps without heatspreader.
Average copper base/ lapped alluminum base = same temps with or without heatspreader
lapped copper base = lower temps without heatspreader.

I used my Aerocool HT-101, I had it on my socket A but it has fittings for s754, and it works very well

Thanks fro the suggestions regarding bolt-on HSFs. After a couple of hours searching t'interweb, I have come to the conclusion that there is no such thing as a cheap bolt on HSF.

I had the idea that if I were to take it into the metal-shop at work they could re-engineer the heatsink so it no longer rests on the retaining mechanism but on the top of the CPU. I suppose It is possible that there are designs that are meant to rest on the chip but of course you can't always tell how they fit from a description or a picture.

op, y did u have to take a dremel to it? i'll b keepin my fingers crossed rave's solution does the trick 4 me it didn't work! doh! u say file them down to about 1.5mm? if i go too far will i nacker the cpu? (squashed?) how can u get a file in there as it's nearly in the corners?
