I only have one hard drive and one SSD, but I do have a big 7800 GS, 4 PCI cards installed and additionnal fans. So far so good, it used to crash at +- 43 degrees but now it can go as high as 50 no problem. It probably means heat was not the main issue.
Make sure you note that the G5 has never been overclocked, even when messing with the resistors. Don't give false hope to those looking to do it.
I'm surprised you didn't link anything to the OpenFirmware clock change. Also, you can't overclock a Cube's bus to anything but the stock 100Mhz. Thousands have tried. There are many threads about it on CubeOwners, all with the same nothing results. Why put the Cube and Sawtooth in the same category? The Cube's full sized companion is the Gigabit Ethernet not the Sawtooth.

Yes they are. They have been marketed as such. They even say "PowerMac G4 Cube" on the backs of them. Their official title in every Apple documentation from the box to the copyright text on the restore discs states "PowerMac G4 Cube". And why put the Cube and Sawtooth in the same category? The Cube's full sized companion is the Gigabit Ethernet not the Sawtooth.
And Cubes overclock to 120MHz. It is in the same category because bus settings are the same as the sawtooth.
Even 120Mhz doesn't work. CubeOwners has tried that as well. The Cube doesn't even have FBUS jumpers on it's logicboard for that. If it does, they have yet to be discovered after 13 years of looking and the board is only about 8x8 inches big.

"ok I did this 120Mhz FSB mod a few weeks ago and have now installed tiger...
Everything is good no noticeable probs yet but I am going to upgrade to a ATI 9250 shortly as finalcut express HD won't install with my stock rage 128 sad.gif (it's not quartz-extreme!!)
I will eventually upgrade/overclock the FSB to 133 when I get a new processor.
I am unsure as to what difference if any editing the open firmware does?
I ask/state this as I changed it several times (processor and FSB speed) and it did not seem to make a noticable difference to anything.
also To Flyrod how did you get such a high benchmark? the closest I can get with my stock 450 is 65-68? I used the current ver 1.1.3 of xbench. It maybe that your gfx card boosts it considerably as my rage 128 does not really cut it but my HD (a WD 12GB w 8Mb buffer) really helped it.
In any case this is stable (for me atleast) and runs tiger well.
BTW the values Flyrod posted are incorrect for the OF edit
I dl Hextoaster (a hex-dec-bin-ascii calculator) and worked the values myself.

And there's the magic golden OpenFirmware modification. This has long been touted as having the ability to overclock a PowerPC Mac's fbus. When really, all it does is change the reported value. Much like how OpenFirmware is used to trick Leopard into installing on sub-867Mhz machines. Here's the post directly after your quoted post:

I am using this exact same process to show my Cube running at 5Ghz with a 400Mhz fbus. Makes me smile when I see it.
Er, that's not how condensation works, in fact that's the exact opposite of how it works.
How it does work, is when warm air hits a colder object the water condenses out. Look up 'Relative Humidity' on the net.
Some folks were either asleep in their general chemistry class or didn't take it at all.
If I had that explanation of supercritical fluids on an exam, I'd mark it wrong
That was a very old post. and I was trying to give a simple explanation. Actual refrigeration is obviously more complex.Some folks were either asleep in their general chemistry class or didn't take it at all.

Any idea where I can get some of this solid helium you mention?
My department at work probably has a couple hundred liters of liquid helium on hand...
It will be easier to hit the llamada point where queed things happen. Solidifying it will be incredibly difficult.
Well, below ~2K at atmospheric pressure you get superfluid helium, which is quite interesting even in its own right.
None the less, you were the one that brought up solid helium, which is possible ~10atm at ~2K or less. Go up to 4K and you need over 100atm, but it can still be done.
I still have no idea what you were even saying in your original post that I commented on(or your most recent one for that matter) but it seems that you don't have a great grasp of what you're trying to say.
