Re: New Solar PV Array in Maynard, MA!

Yes, for solar the power factor (the percent of power generated from the maximum) is around 30%. For a 1MW array, you'd expect peaks in the middle of the day (assuming it's sunny) that might get close to the max, but averaged over the day it should generate 7.2MWh instead of the max 24MWh. This arra...

Re: Reasonable temps for Xeon E5-1650 (equivalent to i7-3930

Yeah, I have a dual xeon system where one cpu is usually in the 70s, and it seems ok. It's a little hard on the power supplies, but the cpus seem to be doing fine.

Re: What would be a silent PSU that has 2 x 8 pin CPU plug?

The reason you want a single 12V rail is that the cpus can potentially draw a lot of power, and in that case you'll have to make sure that the 12V rail you hook one of the cpus up to can support that power. The power draw is also much higher at start up, and the board won't even boot up if it can't ...

Interesting question. Here's a fun coincidence, I have that motherboard, and I'm currently on my 3rd power supply for the system. Whatever power supply you get, and this is very important, MAKE SURE IT HAS A SINGLE 12 VOLT POWER RAIL. One disclaimer, my system is fairly high powered, a dual E5-2687W...

Re: need some input from people about a case i plan to build

I've thought about multi-motherboard cases before, more for folding farms than this sort of application. You will want some exhaust holes on the back of that case, I assume you're just leaving it out of your diagram. If you take the bottom two motherboards and flip the top one over, you might be abl...

Yeah, you probably won't get subtitles, but I'm not sure. I think for subtitles you'd need a tuner, and the external hd thing just gets video as far as I know.

OK, from what I've been able to google about Shaw, it looks like all their digital stuff is fully encrypted, so if you can get analog signals from them, that's probably your best way to go. Unfortunately, since the US has moved to digital over the air, nobody really sells analog tuners any more. I p...

Yeah, the gtx 600s are really power efficient in general. I'm tempted to pick up a gtx 670 and wait for the optimized core, but eh, I have a couple of 560s now, no real need to upgrade. But if you do get something, let us know how it goes.

Re: SPCR Folds Team Blog

Hard to say what the best video card is these days. The nvidia 600 series cards use less power, but the folding engine isn't optimized for them yet. That's in beta, may be coming out soon. In the meantime, the sweet spot for pure ppd/power is probably the gtx 560, maybe the Ti version.

Re: Cordis's Next Folding machine

Heh, now that would be sweet. But I'm guessing they'd need a recompile of the core, and since they haven't gotten around to one for the nvidia 6XX cards, doubt they'd have one. On the other hand, these things looks pretty promising... http://www.anandtech.com/show/6017/intel-announces-xeon-phi-famil...

Re: A quiet dual xeon system

I use it for folding at home, it does a lot of math for the power it consumes. It is fairly quiet, although once I get the case put back together it should be much quieter. I'm currently hearing a little coil whine, but the case has heavy panels with insulation, and it usually cuts that pretty well.

Re: Hot hot hot !!!! 80xx projects

Yeah, I've been getting these on my dual 560ti system. I noticed the fans ramp up, had to downclock one about 10%, and the system is still burning about 50 more watts. On the bright side, both are up about 25% ppd, so I think in total I'm up another 9k to 10k ppd. So, it's not so bad. :)
