Quicksilver 800 MHz upgrades
« on: April 16, 2023, 01:34:36 PM »
Just curious, what are my options as to upgrading the 800 MHz CPU in my G4 Quicksilver? I'm happy with 800 MHz, I think it's a sweet spot, but if I could chuck in a 933 MHz or higher and it was officially supported, well, that would be alright too!

The more powerfull is the Dual GHz from QS'02, but you will need its heatsink or a dremmel.

QS'01: 733 little cache memory (compared to DA'733), Dual 800

QS'02: 800 (I think little cache memory), 933 and dual GHz
Looking for MacOS 9.2.4

Thank you for the info! I might grab a 933 as I really have no use for dual processors.

Has anybody had any experience overclocking a Quicksilver? How far could I safely push my 800?

for the QS (as opposed to MDDs) there were sonnet cards as proper solution, for boosts up to ~100%, single and dual 1,2, 1.4 and 1.6 when i remember right, the 1.8 model has been pulled one year after release because it went too hot.

in the cube and some graphit G4s you could go from 400/0.5M to 1200/2M with those options. the step from a 733/0M to a 1.4/2M is also a speed boost in that same area.

note that the 733 mostly sucks for not allowing huge disks at the internal IDE.

The 933 also has 2MB cache and is a total beast with audio as a single CPU, also the 820-1342-B QS board, as discussed a million times, can take huge hard drives,  The rev "B" board is common in the 867 and 933, but it is a crapshoot since I have seen the rev "B" in 800 QS models and the 820-1276-A board in 867a and 933s (so check your board).

You should be able to bag a 933 QS CPU very cheaply, I think, and it is very stable and fast, no need to overclock.

Yup.

Just swapped a 933 MHz CPU onto a 820-1276 A mobo (that was stock in this original 733 MHz) about an hour ago. EZ-PZ!

An 820-1342-B mobo (via eBay) scheduled to arrive tomorrow… so can then use HUGE (larger than 128 GB) HDs / SSDs. And then I’ll also do that QS Bus Speed hack. http://macos9lives.com/smforum/index.php/topic,6079.0.html

So nope, I wouldn’t "dick around" with overclocking an 800 MHz QS CPU.

I've always found that once I start dicking around with my hardware like that, there's a good chance it just makes things worse.
