My Kill-A-Watt report.

[alucasa]

My Kill-A-Watt arrived and I went through power testing.

I made two records. Watt during booting and Watt while BONICIng.

Platform : Watt usage at boot / Watt usage while running BONIC.
QuadFX : 331 / 356
Dual woodcrest : 144 / 181
Merom : 77 / 49
Brisbane : 100 / 112
E6400 : 138 / 137
Dual Opteron 242 : 139 / 136

:fact:

I'll post my results as well then:

~1.5-2.5kW when powering on my whole room including lighting (blows the circuit breaker), ~800W total when in use (hardware only). D820, 3x P3 ~1Ghz, 850Mobile, 19"CRT. I measured 'booting' at direct startup (so with HDs spinning up as well).

D820 @ 3.4, X1300 (4HD): 350/300
P3 1.13, MX200 (8HD): 300/140
P3 1.13, TNT2 (1HD): 120/90
P3 866, Mil.G400 (1HD): 90/70
Lappy P3 850Mob: 50/40, 40/30 (screen down)
3Com SuperStack 630 24p switch: 40W

Are there any similar reports for Kill-A-Watt for various CPU utilization? (30%, 40%, 60%, etc.)

[Vapor]

How much are these Kill-A-Watts? :D

Sounds like a fun little tool :)

So 3.24A * 110V = 356W :D

Can someone tell me how to measure Amps using multimeter and a power strip where PC is plugged? I know I have to set it to say 10A and hold it not for a long time, at least thats what I read but where do I put the connectors? I am asking cause physics is not my strong side and I once tried it but did obviosuly something wrong cause my power strip blew up :(

I know my measured voltage is around ~224V here overseas

Here is a makeshift diagram I used. How I understand it, to measure current, the DMM must be part of the circuit.

The Kilo-Watt is much more safe:) Check your PM.

[[XC] riptide]

Check my Thread in the vault area.

QX6700 3.2Ghz 100% Load 215W (229 less 15W for switch plugged in)

DX1.6LV @ 3.1Ghz 1.55vcore 180W 100% Load (195W less 15W for switch plugged in)

Anyone notice the peak when you turn on a CRT monitor. Depending on when the Kill-a-watt displays the wattage... my setup peaked at 800W for a split second :shock:

Notes: Both crunchers have basic PCI card. DX has 2 HD's, Quad has one.

[[XC] Jaco]

I don't see the point in undervolting & underclocking the quads

It will be a little slower but still consume too much power , still not very efficient.

Sell it , it's a powerhog!

[Martijn]

Some systems are worth more as a cruncher in a whole rather than parts alone... Same for the D820...

[Vapor]

to measure current, the DMM must be part of the circuit.Indeed....trying to measure current parallel to the circuit will blow the DMM's fuse. Must be part of the circuit.

1 CDRom
OCZ 850W GXS.

I benched Aquamark, 01, 03, 05, 06

Peak usage spike was 450W out of the outlet, don't really remember what test, but it was just bouncing all over the place because the load constantly changes.

[alucasa]

Nothing beats Merom/Yonah with performance/watt ratio, it seems.

My merom rig uses 49 watt because it has a Geforce7300 in it because its onboard video died. With onboard, it would probably use close to 40watt.

[meshmesh]

Very informative thread. Some eye opening numbers too. Will take some time to digest. Thanks.

@RangerXLT8: Unless the PSU has active PF correction, the ampere figure will be highly misleading. And Watts will not equal Amps x volts for the obvious reasons. Just thought to point it out.

ive got my report:D i am running enough to blow the breaker:D my mom was ironing (the same breaker channel) with our old iron that draws about 1kw then boom!! all of my comps went down along with the iron:D but i have a plan to use extension cords and tap into other parts of my house:D :D but i would still like that quad fx:D even though it would make breaker blowing more common.

[Danger30Q]

I tested my 24" Sony CRT and it consumes about 200 watts while running. I didn't know that they consume a lot more than that while booting up. I'll give that a try sometime.

[alucasa]

I am not certain *yet* that I will sell the rig. I am currently in progress of downsizing my NAS rig (which is what my quadFX is used for). My new 2U chassis is already on its way. With 500gb HDD becoming much less expensive, I don't see much points in keeping twelve 250gb HDDs.

http://img262.imageshack.us/img262/3194/ca21706tlgkj7.th.gif (http://img262.imageshack.us/my.php?image=ca21706tlgkj7.gif)

That chassis will be my new nas case.

The quadFX will go into the chassis and I will downgrade the cpu to a possible watt usage of 200 to 250. If that is not possible, or that makes the whole rig sucks, well I will sell then.

Meanwhile, parts for my 6th rig yonah are on its way. I plan to turn off my Brisbane rig after the yonah rig's complete.

[jspace]

I think alucasa's got a good idea going. Yonah/Merom in 1U chassis rackmounts. While individually they may not make much, if you put them in a rack it starts to add up. One of the big drawbacks, AFAIK, is the cost associated with starting a fam like this. Throw lack of OCing and :shrug: One thing I think also hampers people from getting systems like that is the lack of coolers for S479.
Now imagine a huge rack full of those dual Merom boards...
:bananal:?


ps: Why can't I see the FS section?

[alucasa]

Coolers come with motherboard package generally. So, it's not an issue.
OCing is not very possible due to nature of s479. But a Merom T5600 does 4500 points a day, which is not something you can scoff at.

[Martijn]

It was something I planned for the future. I've had enough of those power-consuming chips... Heck, I'm even trying to undervolt my P3s :eek:

If I am ever going to build a farm, it would be something like a full Merom rack. Now the money to build it :p:

Usually here in the U.S though, you do not get billed on PF, usually just the actual amount of power something is drawing

this would be a pretty good cruncher, huh?

[uclajd]

I'm running a dedicated distro box (Folding/BOINC). I have a i975Xa-YDG (http://www.aopen.de/Products/mb/i975Xa-YDG.htm) running my old laptop's Yonah (1.66 @ 2.1) T2300 and a X1900XT @ full OC'd voltage @ 769 MHz. The T2300 is BOINC-ing (WCG/Rosetta) and the GPU is Folding. I wanted a dedicated GPU Folder that was as low watt as possible.

Kill-A-Watt shows at full load 261W. That is pretty low when you consider an overvolted, overclocked X1900XT @ 100% load plus BOINC/WCG on the other core.

If I kill the Folding GPU, I am at 150. Not bad, since it includes a DC waterpump, several fans, HDD - and an idle, overvolted X1900XT. I should at some point test it with an old PCI GPU to see how much of that 150 is the idle X1900XT. Yes Merom would be lower watts, but the Merom is in my laptop (it replaced the Yonah) - doing WCG 24/7. ;)

I haven't had time to do the Kill-A-Watt on my other Folding GPU/D2OL rig (in sig), but I am scared. :eek:

Oh, and the Quad Core is NOT a power hog. It has 4 cores for crissakes! It is incredibly efficient. 80W per core on a desktop? I'll take it brother! Compare that to a single core Pentium!

^^^^QFT^^^^ My QX6700 at ~230W (after vcore increase) / 4 = 57W per core.

[STEvil]

If anyone ever manages to get that dual yonah mobo for dirt cheap, hook me up!

[Duh]

For the time being IIRC the lowest price at Froogle was $350 for the mobo... and regarding the merom chips the 7600 was about $750 each... you ll either have to wait or call David Copperfield:D

[alucasa]

Merom T7600 is waste of money especially for a cruncher.

I am settling with T5500 and T5600.

P.S. The Tyan dual s479 motherboard is said to support Yonah only.

[Got Chow]

My dual opty at 2.8GHz (1.35vcore) runs about 220W from the outlet. WC'd rig with full accessories (several drives, PCI cards etc.).

My dual 1.6LVs @ 2.6GHz (1.5vcore) runs about the same. Again, WC'd and full accessories.

I have an undervolted Dothan laptop that only pulls 24W from the socket with the screen closed.

My Macbook Pro also undervolted with a Merom pulls 45W from the socket with the screen off.

Watt for watt, the merom is kicking butt!

Your sure it will support a dual Yonah and not just sossaman?

[alucasa]

Well, according to Tyan's compatible CPU table ( http://www.tyan.com/support_download_cpu2.aspx?socketid=3 ) (It's Tiger i7520SD ), it does state Core Duo T2500. It doesn't even say that it will support sossaman though.

Lack of clearer information is what has been keeping me away from the board.

Edit : The PDF manual states sossaman and sossaman only. However, the manual also states that we should refer to Tyan webpage for compatible cpu list. It's too confusing.
