So nobody has yet said that they donâ€™t consider power efficiency at all. Is this because people who feel that way have automatically ignored this topic, or that they donâ€™t like to say?
What I would really like is a way to fold while using cool and quiet so when the server needs more power for transcoding it can pop out of cool and quiet, do the work, then return to CnQ and still continue to fold at 1Ghz and 1.1V.
It would be nice to be able to restrict a task to a certain percentage of CPU cycles. Some applications will allow you to limit the CPU cycles that they consume, does Folding support this? If you have a dual core CPU, you could limit the max CPU clock using RMClock and then assign Folding to one of the cores and set its Priority to low. This way the server could use one or both cores when needed, depending on if itâ€™s multi-threaded and when itâ€™s finished its work Folding would grab back a single core to do its thing. Not exactly what youâ€™re after but a compromise of sorts.
With AMDâ€™s quad cores offering individual clock speeds per core, itâ€™s possible that CnQ for these CPUs could even allow what you suggest. Letâ€™s hope the dual cores also support this individual core clocking, which seems likely!
Not many choices, are there?
Well Iâ€™m open to other ideas, what do you have in mind?
BTW, to the OP, when you look at energy inefficient rigs, you have to consider, that not everybody jumps on latest and greatest. I still have P4c in rig, and I'm not going to change it for another year because it does everything I need to and changing it would take too much money. Upgraging right now for the sake of gaining extra 20-30 watt doesn't make sense.
Generally speaking Iâ€™d agree with this. For those people prepared to buy and sell on eBay, the cost of upgrading doesnâ€™t have to be that large; itâ€™ll vary a lot depending on what youâ€™re selling and what youâ€™re buying of course.
Iâ€™m about to upgrade two machines for family members and when I looked at the cost difference between Yonah/Merom v Conroe v AM2 using my particular purchasing methodology, the Yonah/Merom route stood out as the obvious 1st choice to me. This decision also takes into account how the PCs are used as well of course.
The biggest stumbling block for me at the moment is finding an inexpensive highly efficient power supply in the PicoPSU mould. Iâ€™ve found quite a few options ranging from 60W up to over 200W that use a fanless power brick and DC/DC board. I need to determine what wattages I need for various systems and then bite the bullet and buy a number of them and see how they compare.
They mainly seem to be using 19v power bricks rather than the 12V of the PicoPSU; Iâ€™m wondering if the PicoPSU will be significantly more efficient because it doesnâ€™t need to convert 19V to 12V. Any ideas?
