I have a machine with a pci815ve card, it arrived with the cpu out of socket. I ordered a 1ghz cpu, the max supported by the board and voltage. Problem is, the old cpu had the heatsink glued to it with epoxy of some kind. There's no retention bracket points on the socket as it is non-replaceable cpu style (push) socket. The cpu is held to the heatsink by thermal pad. If you remember p3 cpu, it has a small core and no heat sink spreader. You must make the heatsink and cpu flush with each other, normally done with compression clamp. I would make shims for the correct height between cpu and heatsink, put on thermal pad as it is sticky and won't move much as ps2 tool is vertical, make a ring of the thermal epoxy around the thermal pad, lower the heatsink and let it cure. I think this is sufficient for such an old and cool processor. I only ask in case someone has a better idea.
I'd look into the old p1/486 style heatsinks for an answer- I haven't compared socket sizes, but many of these sinks use a clip that clips under the very edges of the chip, then goes over a flattened section in the middle of the sink... with a decent fan on it, it should be fine... P3's are nice that they really stay quite cool.
nod- I'll run it buy a few people I know and see what embedded sinks they've seen- the thermal transfer glue IS one way to go, just an unpleasant one...
I looked for ages, and found ONE site with a snap over PPGA/PGA heatsink. http://www.orbitmicro.com/global/cf-506-p-1326.html?ref=base FC-PCA won't work. The problem is it's $30 shipped. Progress so far: Using the manual I set the jumpers to oc the bus to 133mhz I found the TDP for the CPU http://processorfinder.intel.com/details.aspx?sSpec=SL52R This is the optimal cpu to use, took me ages to find the 1ghz It has a TDP of 29W I have decided to use arctic silver epoxy, which can handle up to 50W Plan: Thin coat of epoxy on top of the core, and a ring around the edges, four blobs to secure it to the cpu itself. Once this is done it will be bonded to the cpu permanently. I also found the PCI-815Ve manual in english. It supports 4 usb. I plan to add usb ports to the system.
Very interesting... This is quite the interesting thread. Very cool idea. What sort of performance gains do you think you'll see on the CP with this? (Totally vague question I know, but, just curious.) I assume you are heading into uncharted waters here, as in, no-one that anyone on here knows of has done this before? Either way, very cool stuff, and, with the number of new PS2 Tool owners on here (Assembler's 12, plus the one I just got from the UK, so that's 13...) this is a very cool time to be showing off such a cool mod. How much did the cpu end up costing Assembler? Regards, npt
You can get P3 CPUs for cheap on ebay these days. I got a matched pair of 1.26Ghz P3 Xeons for £10 or so from blackmoreit on ebay, the fact they don't work though is another question though I do believe that's more down to IBM lying about what an X330 server supports, but who knows.
Can't wait to hear how it works for you. Should be interesting to hear where you gain performance and where you don't, etc. This would be a great thing to put together a PDF about, I am sure there are people that would love to try it. Not to presume anything, just mentioning. Regards, npt :Rock:
