24 q6600's and 48gb of ddr2

[MarcVenice]

Check the link: http://helmer.sfe.se/

So that means each q6600 only uses 25w ?! Not to mention the ram and the mobo's. Something is wrong here, it's more likely that the renderfarm uses like 2000w ??? Anyone any idea's ?

Read your links, Marc. He put 6 Q6600's, 6 Gigabyte G33M-DS2R's, 12x4 GB sticks of RAM, and 6 hard drives in his render farm. At first, he claimed it was only going to use ~400 watts of power, but after actually getting it up and running, he said it uses ~800 watts, which sounds about right to me, since all six boards are using onboard video.

 

[hoihtah]

by using newer cores, he should be able to get that wattage down a considerable chunk.
perhaps around 600w.

24 cores worth of Q6600s

Yup.

The guy was dreaming or confused or both.

My 5 quads take ~230W each when fully loaded. Granted that's with them overclocked to 3.3GHz, so at stock they probably would take less than 200W fully loaded.

But still that's a huge gap between 1.2KW and 0.4KW.

 

[MarcVenice]

Oh shit, I was confused lol. Damn I'm stupid

Yeah, 6 quads at 800w with the mobo's and ram sounds about right I guess.

 

[Idontcare]

Sounds right for 6 rigs at idle.

6 x 200W != 600W

 

[aigomorla]

lol my 4 rigs could probably outproduce his 6 rigs. :T

I was actually thinkn of building a rack like that for my twins. Something where i could have both of them in 1 nice little cage since there WCG dedicated.

Havent had the time to do the project tho.

Quads do not eat 200W each, that's ridiculous, it's about 100W max, with a board, hard drive and ram I'd say definitely under 150W load. Look at Anand's reviews of graphics cards where they measure power consumption. Those numbers are WITH high end graphics cards, without them numbers drop dramatically.

And 150 * 6 comes out to 900 so I was right about 150 being the upper limit.

Either way, he really should have used 45nm quads, it's like $20 more each.

So, has he overclocked them or not, that's the big question. I bet he could get some awesome PPD out of those if he OC'ed, but power consumption would be through the roof. Think it would exceed the power available on a 15A 120V household circuit?

 

[firewolfsm]

My power consumption went down after overclocking. See sig.

It's possible on most Q6600s as long as stay under 3GHz.

and larry how far do you think you can overclock on stock heatsinks?

You do realize I have 6 quad systems here at my house, and a kill-a-watt for measuring power consumption?

Obviously no one here is saying the quad uses 200W, we are talking system power consumption at the wall.

And yes they do use >200W per quad system when fully loaded. Specifically mine use 220-230W across the board. Sorry if reality doesn't match your ideals.

Graphics cards?

Not quite but pretty close.

Radeon X1550 Quite pathetic little cards that only run in 2D for my cruncher application for which I am referencing my fully-loaded power consumption numbers.

Mobo's are DS3L's. 2x2GB DDR2 kits on all comps. Stock voltages one everything across the board except the CPU's which vary from 1.27V to 1.35V across the comps.

At idle with speedstep and everything to save power enabled I see 70W drawn from the wall. (these computers are "headless" meaning no monitor, keyboard or mouse...all interaction is done thru ethernet with remote desktop)

Fully loaded they draw 230W when doing small FFT on Prime95. The variation across 5 identically configured computers is about 10W, which actually surprised me as I expected more variation.

My systems do run fully loaded 24x7 performing financial market analyses (mechanical trading system) and they cost me about $15 per rig here in Pennsylvania. (PPL provides nice daily power-consumption graphs online for your accounts, easy to see when I shutdown for a day to do maintenance or the random weekend that my systems can take a break)

Bottom line is that unless that guy considers running IE7 or MS Excel as being fully loaded there is no way 6 fully loaded Q6600's is going to use anything less than 1KW, and it should come out to be more like 1.2KW.
