overclocking the 32mb 3d Prophet II?

[mad hampster]

From what I have seen and read the heatsinks on the ram on this card are very poorly attached and thus actually trap heat instead of dissipating it... Can anyone give me suggestions on how to properly cool the ram so I can overclock it to a higher value: putting in thermal paste, etc?

I like the idea of the heatsinks on the ram, and my creative card(geforce2) doesn't have any, so I got two 486 heatsinks and cut them into four, giving me eight minature ram chip size heatsinks, I then lapped the chips and heatsinks, then put a tiny microdot of superglue in each corner and a very thin layer of thermal paste over the rest of the chip and that's it I now have quite good cooling on my ram chips, after only just doing this I thought I'd post this to you instead of as a new topic, hope it's of some use, anyone correct me if I'm very wrong, but don't flame me too severely.
John.

thanks, where can i get 486 heatsinks

[JohnRobins]

try lapping your existing heatsinks first, 486 heatsinks are just like pentium processor heatsinks but smaller, should be able to get these from any computer hardware store, or any old system!

oh ok, can anyone explain to me how to lap these things or can anyone direct me to a webpage about how to do it?
Thanks

thanks, thats a bit scary for me...is it ok to just put in thermal goo stuff without sanding my ram?

[JohnRobins]

Of course. but you could lap just your heatsink without too much worry though!

oh ok, I can do that, thanks!
