My Q6600 is drawing ~145W with BOINC RAC of ~3700 so about 25cr/watt
The E6600 is drawing ~140W when crunching for BOINC, But is sons gaming machine therefore hi-end graphics card, so RAC is lowish by comparison but best guess is ~12cr/Watt.
The Pent M 750, draws ~68W and has BOINC RAC of ~600, 8.8cr/watt.

Retired computers incl dual P3 and AMD 2000+ both drew over 150W and had RAC's no higher than 250. i.e. less than 2cr/watt.

Would like to see the Pics of your rack.

Very nice set up Andy!
I have the same rack and recommend it to all that are looking to keep their farm breathing well.
I so wanna upgrade to atleast ONE quad but money is tight with the wife ill.
Outta curiosity.. what kinda money did that last Q you build run and what sorta 'extras' ar in it.. HDD, CD.. ect...

Well the cost to me was £43! I sold a load of rubbsih from the garage to make room for the computers and used the money to buy the bits for the Quad!
The real cost was £258. Q6500, motherboard, case, 250Gb Sata drive & 2 * 1Gb sticks of memory. I already had a spare DVD drive.

Bad news for us Brits.

How palatable does a 46% rise in your annual fuel bill sound? :(

Doesn't sound very good does it? In US I complain about a $100/month electric bill. We have some exterior lighting that is on every night from 7-10PM about 6 flood lights (thinking about replacing with newer efficient bulbs) but very low watt landscape lights...some are solar powered but problem is with batteries that just don't last through weather.

With my computer Farm (borrowed term, very descriptive), win xp, desktop + laptop; 2.4 and 1.8 speed; super iMac 2.4 along with old, old, Toshiba laptop...less than 1 speed; and iBook, G4 all working maybe average 3-4 hours/day (Some machines longer) I have often wondered about power usuage. Will have to see if I can locate a meter to monitor that; doubt if it is much effect, compared to some of numbers here, but interesting to check to see, however.

Since increasing use of more computers in my "Farm", certainly have seen increases in credits.

Good info on this thread! Thanks,

Would like to see the Pics of your rack.

For some reason I assumed a rack would just hold all the parts with no cases....Looks cool though.

If I hadn't already built the machines before I moved them to the garage then I wouldn't have put them in cases and would have put them straight onto the racks I think. SETI Farm phase 2 (Intel build) might kick off after my holiday and that will most likely be the very bare bones scenario.

I am considering taking the computers I am retiring apart and making real wallpaper with them. I already have one on the wall maybe it would like some company. I used drywall screws and screwed the MB right to the wall because someone here told me a computer wouldn't work without the case....

Hey, maybe SETI Farm Phase 2 could be wallpaper? No reason the computers wouldn't work screwed to the wall - and it would save space too :D hehe, sounds like a great idea.

LOL......I luv computers as art.......I run all of my rigs with the case sides off......partly because I have to twiddle with them now and again because I am OCing the crap out of them, partly because of cooling, and partly because the kitties and I can spend countless hours just watching the little electrons swirling about whilst doing their little Seti tasks......

That is still a classic, dude.

Gotta love that pic. Personally, I would have tried to rotate it 90 or 180 degrees, so that there isn't as much cord hanging from the monitor, lan and power connections. (I hate it when I bust a motherboard)

Try a Kill-a-watt, I have heard they are excellent tools for checking power usage. I just ordered one.

Turn the cases the 90 degrees and you can get three per shelf.........LOL

Believe me when I say I've been there! I had 16 computers all stacked in the garage until I put the quads on this rack. The reason I had to make the changes was because the heat build up was mad and kept causing failures.

This was my early farm:

I don't get any problems with the Quads now and have an "uptime" of 38 days on most of them and counting.

(That's the length of time since the machine was last reset)

Couldn't you save money AND electricity by NOT using a hard drive in most of your units? But instead let all computers in your farm share a single hard drive after booting via CD or LAN?

I've had a couple diskless clients & it works great.

If I could get my head around this I'd love to have given it a go, but I think it is stretching my computer abilities too far :(
