F@H & Power Consumption. Look no further.

The more efficient the PSU the better. But otherwise yes. Too bad there aren't any Core i7 boards w/ intergrated video, a lower power graphics chip like that might save a tad on power as well.

Yes, and 'tis a wee bit more than a tad less too.
I'm pulling ~275w from the wall at 3.8ghz with -bigadv -smp 7.

Which is about $11.75/month w/ Calgary's current power rates. I am assuming that is w/ no GPU client running?

i7 machines running -bigadv are currently the most power-efficient setups possible for running F@H.

well yes, cant skimp out on psu. 80+ is a must. question is, will you go for a 75 dollar unit or a 150 dollar one? no video card of any important wattage, of course.

Good job lowfat! Common question so we can refer to your results in the future.

[Soultribunal]

Yeah BigAdv are the way to go for power efficency.

However if you can't afford the massive rig and its setup you can always opt for a pair of GT240's and a small AM3 chip.

My Practice on that had me only pulling 186 from the wall.

Holy crap 5.951 cents per kw! In NB it is between 9.69-9.22cents/kw, but 17.78 cents per kw once you add in all the tax and service charges. Some might argue you can't include tax + service fees....but the way I look at it, it still adds up to cash out of my wallet.

So in NB it would be for - Running 8 thread -bigadv -> 430w = $55.04
If I used the 9.22cents/kWh = $28.54 a month. But I would only be kidding myself.

5.951 cents/kw, does that include service fees and taxes?

The effect taxes and service fee has on your approx kWh cost is crazy -

Service fee = $21.63

1300kw/hrs @ 9.69cents/kWh = $125.97
1629kw/hrs @ 9.22cents/kWh = $150.19

Water heater service = $5.84

HST = $39.47


Total = $343.10/1929 kWh = 17.78 cents/kWh = now I will figure out my approx folding cost.

Maybe I am wrong...

Wow, that's very high idle. I thought normal idle was ~150W. Do you have speedstep enabled?

In the first post I've said I have disabled it.
