Dual 800MHz in 733MHz QuickSilver - heatsink

Hello everyone!

I just had a PowerMac G4 QuickSilver 2001 (the original model) with a 733MHz single CPU from a good friend.

I want to upgrade the CPU and I already know that the CPU from the Dual 800MHz Quicksilver will fit and work in my computer, but my question is about the heatsink.

The Dual 800MHz CPU I saw on eBay doesn't come with an heatsink, so: can I use my heatsink from the single 733MHz with the Dual 800MHz or will it overheat? I could put a second 60mm fan attached to the heatsink to improve the airflow, will it be enough cooling?


Thanks!

PowerMac, Mac OS X (10.4.11), G4 QuickSilver 2001 - 733MHz - 1GB

Hi, it won't fit or work, you do need the DP800 Heatsink, preferably the copper one.

I wanted to run Xbench and compare it to my 1.5GHz PowerBook G4... and they're really close! The PB is still a little bit faster, but the QS has a 7200rpm hard drive that helps a lot... 🙂

I tried my old 9600XT from my G5, taping pins 3 and 11, and it doesn't work... nothing at all. 😟 I'll try again with the X800 as soon as I can 🙂
