We’ve worked with a number of P45 motherboards and have come to the conclusion that it is more sophisticated than P35, which manifests itself in some re-jigging within the Bios that takes effect when you overclock your PC.
With P35, it was a doddle to overclock your Core 2 processor as you could crank up the FSB until it got flaky then you’d raise the CPU core voltage by 0.1-0.2V and pump about 0.4V extra into the northbridge and CPU VTT settings. That would sort out the stability and allow you to raise clock speeds further without any risk of damage to the processor or motherboard, which is pretty much the ideal situation. With P35 you need to increase voltage to keep the clock wave signals strong to maintain system stability. As the clock speeds increase the waves become less precise but more voltage rectifies the situation.
Longer bars are better
With P45 it’s a completely different situation due, we presume, to the new 65nm fabrication process. You no longer need to increase voltages to maintain strong wave signals and it has become necessary to keep the northbridge voltage as low as possible to keep your PC running properly.
8Gb vs 16Gb might not seem real worldly, but I have Q35 desktops deployed with 8Gb already and the entire ram complement is being used. If 16Gb was available, I'd deploy it.
Why? Astrophysicists eat ram.
The alternative to putting this amount of ram in a personal desktop system is buying in servers which cost 5-10 times as much and then having them fight over CPU time. This results in less effective work.
Dangers of Cross Cultural Misunderstangs
Australia at least: An American actress told a story once how she did an interview show in Aus., and she told a story about her car, saying that she pulled over & popped the trunk open. She said then the audience sort of gasped.
@ Joseph Haig
ditto that @ James Anderson. Reminds me of the Australian equivalent of Sellotape. I think it was no more than 2 seasons before Formula 1 cars stopped roaring around European Grand Prix circuits with Durex plastered all over them.
