Water cooling anyone?Originally posted by Sun Baked
I don't call an unstable overclock a success...
Especially when you're talking about having heat problems.

More importantly in that thread, the dual-867 goes to 1067, which completely defeats the purpose of buying the 1GHz, especially when dual-1GHz can only be overclocked to 1167. The dual-1.25 will probably run at 1.5GHz with more cooling, but runs extremely well at 1.3GHz.
Someone could make a lot of money buying a thousand of these, modding them, then jacking the price up $200-$300 and reselling them at their overclocked state.

Water cooling in combination with Peltier heat pumps... Apple has used Peltier units before in their Powermac 7200/90

...the 1.25GHz chip is an MPC 7455A. No one outside of the industry (and not many in it, I would imagine) knows what changes were made going from " " to "A". As for the dual 867 being overclocked, that would certainly mean that the old dual 1GHz was overclocked because they used the same chips. However, since Motorola officially says the 7455 (not A) will go up to 1GHz, anything up to 1GHz is not overclocked. As for the heat. I agree, wtf is up with that? It has a GIANT heatsink with a large fan blowing directly on it, plus 3 more fans in the case. No embedded chip (which is what the G4+ is) should ever make that much heat. If this was the GPUL (<---dumb name), I could understand it, since the POWER4 that the GPUL is based on dissipates 125 watts. So, that leaves the question: What the hell makes so much heat in the new PowerMacs?Originally posted by tjwett
Easy dudes! I thought I made it clear that I was under the IMPRESSION that the new G4s contained overclocked chips. I'm not the only one. Take a look at the discussion forum for the Mirror Door PMs over at Apple's site and you'll see what I mean. Lots of folks over there having lots of problems. There was even one topic wth the title "Dual 867 and Fire" or something to that affect. The attitude isn't necessary and you still haven't given me any real info. Are the chips in the new PMs different than previous G4s? Perhaps it is an issue with trying to implement DDR memory in the new machine? I wasn't being a d!ck so just chill out. I'll ask my question again: What's up with thew PowerMacs and all the probs? The Quicksilvers and Graphites were so solid.
