Practical underclocking and 45nm K10 lower limits

[zir_blazer]

Tested with OCCT Linkpack and it was fine for 11 consectuvive hours, with CPU 1 GHz @ 0.8V and IMC 1.2 GHz @ 0.9V, with temperatures varying from 23°C at Idle and rare 29°C peaks at Full Load.

But as no one seems to be paying attention to this Thread, there is no use on keeping it alive.

I'd be interested in seeing a couple benchmarks at those speeds

wow you even under clocked the Nb that's really extreme
how much less watts does it draw vs the normal Nb speed ?

You tell what ones you like to see. Keep in mind that the less the GPU matters on them, the best, because I'm using the IGP (Radeon 4200), so for gaming is just adequate at very low resolutions and settings or slighty old games.

That is a really good question that I'm wondering myself too, but I don't have any means to measure power usage. While there are articles that did an interesing job on CPU power consumption like the one of X-Bit Labs, they didn't analyze anything about the IMC. I'm basically clueless on the power consumption of the IMC in an isolated state, however, that it should consume less than at nominal settings, that's for sure.
