Power efficiency: post up your most efficient rigs!

[Biker]

Hi all

In my crazed drive for the most power efficient machines vs max ppd I have been a tweakin' and have a couple of rigs up for ppd/w inspection:

Rig 1:

AMD X6 1055T @ 3.8ghz 1.375v

Gigabyte GA890GPA-UD3H

2GB G.skill Trident @ 1.5v (1 stick)

on board gfx (low clocked)

Enermax Modu87+ 600W Gold rated PSU

60GB 5400rpm HDD

Total average WCG PPD (over last 10 days): 21771

Average power consumption (over last 10 days) 161w

PPD per watt score (21771 / 161) = 135 PPD/w



Rig 2:

Intel i7 920 @ 3.8ghz 1.18v LLC on

Gigabyte EX58-UD3

4GB G.skill ECO 7-8-7-24 @ 1.4v (2 sticks)

Nvidia GT220 (stock clocks)

Seasonic X-650 Gold rated PSU

Intel X25-V 40GB SSD

Total average WCG PPD (over last 10 days): 34221

Average power consumption (over last 10 days) 185w

PPD per watt score (34221 / 185) = 185 PPD/w



I also ran rig 2 with a cheap ass PSU for 10 days and it averaged 245w for the same PPD which dropped the PPD/w figure to 140 PPD/w - just goes to show how important a high efficiency PSU is in saving some $



For UK users you can then work out how much you are going to get bent over a till by your local friendly power provider here


Trust me... the results will make you



Also there is a great site here which is stuffed full of all kinds of energy usage reducion tips and covers everything not just our humble folding farms. In addition and almost all of the information applys globally



Just thought I would post up my findings in case the results piqued your interest
