What you crunching with??

[Brucifer]

ah.... feast or famine I guess!! Lol. It's good to see that you are back at the crunching again after your recent bout with the alternative life style that too many of us seem to have had to endure in the past five years or so! :-) Myself, I went and invested in some more win7 and picked up a couple i5 guts to replace a couple of the higher wattage C2Q systems. Also experimenting with an i3 and some gpu's to see what I can do there wattage wise. Definitely not like the years past, but am not generating the intense heat that I was before either. :-)

All my current / recent builds are water cooled using a Corsair H80 system. Sorry no AMD CPUs too weak cruncher performance per watt of electricity and too much heat output. I5 Ivy Bridge seems to be the sweet spot for price/performance they overclock to 4.6 comfortably and temps remain manageable. I routinely put 32GB low profile Corsair DDR3 in the crunchers then any BOINC project that has silly high ram requirements can be catered for. My son installs Gentoo-64 as the OS. Usually put a 256 GB SSD Samsung 830s for storage. GPUs are whatever the wallet can afford on the day.

I forgot to add that the twin Xeon server has been crunching Asteroids too. That box is more set and forget than any of the others. It role is manage the network and crunch like crazy. No overclocking on the Xeons of course but stable as anything.

I have no complaints about the crunching performance per watt for my A6-3500 and especially not for it's successor with me for it: my A8-3820 (both 65 Watt tdp APUs), while the A8-3870K does a pretty thing in credits per Watt too. And no problem with heat output here now: it is winter! It even freezes at night...
It's a pitty the Intel HD 2000 IGP of my i3-2100 is totally useless, the CPU itself performs quite good per watt giving it's two cores with hyperthreading -also thanks to the HD 4770 in that same system, which is my sole MilkyWay cruncher-. Comes money I'll replace it with a i7-3770, but at the moment I have more hopes for a rebuild under Linux of my ASUS F1A75 with afore mentioned A6-3500.
Rumour has it that the Ivy Bridge with their Intel HD 2500 and HD 4000 can soon be used -the IGP already being detected in BOINC >7.0.39-, if only for the OpenCL that is possible on the CPU itself.
