Additional Heatsink(s) for radeon 7500 overclocking?

[xbytes]

I have a T40 and I thinking I could try sticking some of those ram sinks on the memory and core and see what results I get!

anybody tried this before? any reason why it maybe a bad idea other than the obvious risks?

I have already done this with my T30 with mixed results as the stick on heatsink from the old motherboard I used was covering the memory and the gpu, it was bringing the memory temps up to that of the gpu, I noticed this when it wasn't overclocked just having really hot weather as little white dots appeared on the screen removed the heatsink and solved the problem this was six months ago and system is till working fine, but with these small individual heatsinks you could get around that problem!

Hi,

Well, what I've done to my T40 w/Radeon 7500 is basically mounting a T4x LONG fan on it, and made sure it made contact with the graphics CPU and memory chips. I also swapped the Banias 1.5Ghz CPU with a Dothan 1.8Ghz (running at 2.0Ghz thanks to SETFSB).

After these changes, a machine that was *usually* over 77ºC with CPU loaded and/or GPU running now rarely goes over 64ºC, and GPU temps are now fully following CPU temps.... so I can overclock CPU & GPU w/confidence.

Which version of setfsb did you use? I tried some on my T40 ( the one on my sig )but didn't work.

Hi, I used the STEFSB version for thinkpad x31, but I am aware it does not work in all T40's.. not all of them use the same PLL.

I tried SETFSB seems to work on my T40 but should be careful I tried oc by 1MHz worked, but when I put it back to correct setting it locked the system also it runs PCI/AGP bus faster and messes up your speed steps a bit, but it is an interesting little app heh google says its a malware site when I get the SetFSB site through google.
