Wow, electric bill is down $81.46 from last month! That paid for the D510MO right there.

Nice! I got my extension cable yesterday [I always like the speed which newegg gets me my stuff] and I got the a test configuration up. Mine is drawing 20watts up to 22watts under load. Which is about 1/4 what my current rig draws. So that is a pretty darn good. Drive access seems good and I'm going to build out some bench kits to push the little box and see where it breaks down.

PS - I should add that a standard USB->IDE adapter and a gerneric CD-ROM drive was enough to get it to boot without having to give up a SATA port. Smiles all around that it worked nicely.

PPS - The CPU temp was also only 30C under load with only a single case fan [Silenx IXTREMA 80mm 32cfm 14dBA] I'll probably go with 2 fans in the final setup but it's really quiet.

Ah, that's a pretty good idea - I may go that route instead. Thanks much!

Has it been unusually warm there, tho ? Usually at Spring Festival I have to wear three layers and mittens to go outside, this year I might wear a sweater. Or less. And the ice sculptures are all melting at the Ice Festival in Harbin. It's usually about -10* C there this time of year.

I really doubt the old Origin hardware really cost $81.46 to run - as a matter of fact, that seems entirely impossible given the PSU specs.

On the other hand, I'm sure avoiding the noise is really nice

Ever since Enron took California for a long walk off a short pier, electricity has been abnormally expensive there.

What was it I didn't understand about business again, bri3d ?

Yep, power is incredibly expensive, plus usage past certain thresholds (pricing tiers) increases the cost per kWh dramatically, in my case from baseline of $0.11877 to $0.27572 for 131-200% of baseline.

Code:

Selected bill:                          2/09/2010               Last month: 1/08/2010           Bill Impact

Billing Days:                           32 days                 30 days                         +$8

Average Cost per kWh:                   $0.1209 / kWh           $0.1547 / kWh                   -$28

Average Use per Day:                    25.91 kWh / day         39.10 kWh / day                 -$61

Total Electric:                         $100.21                 $181.46                         -$81.25

This month I didn't go past 130% of baseline, using 96kWh over baseline @ $0.13502. Last month I hit the 131%-200% bracket, using 279.64 kWh @ $0.27572.

I used 13.19 kWh less per day, which is a reduction of about 550 watts per hour (0.55kWh). So yes, a savings of $81.25 due to powering off the Origins seems perfectly reasonable to me.

Not to rush to anyone's defense, but I did a double take when I saw the numbers, too. I pay significantly more for electricity (~$.20/kWh) and you saved as much as my entire power bill (~$85)!! My gut instinct would have been that the Origins only draw 300W and saved about half of what you saw. So much for that. Was wondering if its warm enough over there that you need cooling year round with the old system on? (multiplying effect?) The environment doesn't affect my electric power bill significantly - just draft/vent motors for the steam furnace, no AC.

But that's just counting the average use cost, not the tier 3 pricing at $.27572/kWh that the Origin bumped me up to. It's like a tax bracket - using just a bit more power can have huge repercussions on the final bill.

No additional cooling was used - the change was powering off two fully loaded Origin 350 machines, each with 8GB RAM, 4 700MHz processors and two drives (8 CPUs 16GB RAM total).

I'm not sure why anyone would doubt what the bill says? Not sure how other places handle it but California has multi-tiered billing and when hit tier 3 and 4 [SDG&E has tier 4] the price really jacks up. Arguing with fact is rather silly, remember Neko was runnning O350 x2 with numalink. http://forums.nekochan.net/viewtopic.php?f=14&t=16717825 ..... Enough said.

I ran the apache bench this morning I like it.

I don't think anyone meant to doubt - it's just that if you aren't acquainted with the situation it's kind of a shock. More of a "holy spinning electric meter, Batman ! Really ?" kind of thing.

Centos 5.4, the httpd.conf was out of the box I think Max Clients is 150 on RH/Centos I rarely have to tune that.

I stuck a second case fan, the temp are silly

M/B Temp: +90°F (high = +7°F, hyst = -38°F) sensor = thermistor ALARM
CPU Temp: +64.4°F (high = +176°F, hyst = +167°F) sensor = diode
temp3: +61.7°F (high = +176°F, hyst = +167°F) sensor = diode

I'm pretty sure it a least 68F in the house so...

Yeah, I get weird values as well:

Code:

# sysctl -a | grep temperature

dev.cpu.0.temperature: 6.0C

dev.cpu.1.temperature: 6.0C

dev.cpu.2.temperature: 13.0C

dev.cpu.3.temperature: 13.0C

Ambient is 22C, so something isn't right there.

mbmon seems more sane:

Code:

# mbmon -I -c 1

Temp.= 38.0, 26.0, 25.5; Rot.=    0,    0,    0

Vcore = 1.15, 1.06; Volt. = 1.87, 5.08, 12.95, -12.28, -6.91

I like 6C break out the winter parka there might be snow in SF. The mbmon seems about right I checked the BIOS after the last reboot and the numbers are about the same. Still 25C is 77F the CPU is pretty amazing. The heat sink is cool to the touch.

Ah, so that's why the page with the Origin 350 specs was taken down. What are you gonna do with the Origin 350s then, neko?

I'll probably sell them at some point, it's just such a hassle calculating costs, taking care of shipping/packaging etc. that I haven't offered them up just yet. I bought the O350s locally so I didn't have to deal with that, but when I sold/shipped my O300s to France and the east coast of the US it was quite a pain
