I thought there was another thread about this, but I can't find it to save my life. SMF Search sux Anyway, let's see your mining rig efficiency in MH/j (or MH/w, I'm not sure what the diff is exactly). I added another 5970 to my system and finally figured out how to tune down the CPU cores. CPU: AMD Phenom II x4 960T, throttled down to 1-core GPU: 2x 5970 @ 625/150MHz @ 899mv MH/s: 1128 At the plug: 394W 2.86 MH/wWhoa, I think I finally beat D&T!!! Except now he has a bunch of BFL Singles Edit: New numbers after adding another 5970: GPU: 3x 5970 @ 625/150MHz @ 899mv MH/s: 1690 At the plug: 554W 3.05 MH/w

best rig i've got 5xSapphire 5850 xtreme 690-720Mhz 0.95V 1x XFX 5870 ref 0,95V 710MHz some MSI X48 775 mobo with a c2d celeron at 800 mhz Corsair HX850

Wouldn't a sempron get you better efficiency? Probably. This is my gaming rig though I could probably knock another 50W off by going with a low power CPU, which would put me in the 3.1X MH/w range. But that would mean I'd have to swap CPUs to play games, and that's a big hassle.

Whoa, I think I finally beat D&T!!! Except now he has a bunch of BFL Singles I don't have any singles but you didn't beat me either. Still 2.86 is pretty impressive. My new rig configuration: 4x5970 3.2 GH/s @ 1080W 3.02 MH/W That is on 240V circuit, 80-Plus Gold PSU, usb drive running linux, optimized BIOS, underclocked & undervolted sempron, and >3 GH/s per rig. I am pretty sure it isn't possible to get higher efficiency from a GPU rig without undervolting the GPUs. A 4x7990 (or possibly 3x7990) rig will likely beat that though.

I'm still doing some tuning and will soon make the move to a passively cooled water cooled setup but my current measurements show it ranges from 4.52-2.78 MH/W for a dual 6990 rig with the memory underclocked to 150MHz. I run the fans at 50% during daylight hours to regulate the WAF cgminer: 2.3.1 CentOS: 6.2 x68_64 AMD App: v2.5 AMD Catalyst: v11.11 (8.911) Volts: 1.00V Mem Clock: 150MHz (OC BIOS reflashed) MH/s (night time): 926.33 968 MH/s (day time): 795.63 843 Rig Power (Idle): 188.48W Rig Power (night time): 332.61W 567.49W Rig Power (day time): 175.95W 419.92W Rig MH/W (night time): 2.79 MH/W 1.71 MH/W Rig MH/W (day time): 4.52 MH/W 2.01 MH/WDay time GPU clock averages (using --auto-gpu so it varies): GPU0: 434.62MHz GPU1: 470.32MHz GPU2: 501.34MHz GPU3: 500.32MHz The wattage rating is computed from Amps via the current probe of the UPS that provides power to the rig and I am assuming a PF of 1 as the PSU is power factor corrected. I'm still a bit skeptical of these numbers though as the efficiency seems to be implausibly high for the day time...Edit: Revised numbers based on iMeter Solo load measurements at the wall with more accurate cgminer stats

Rig Power (night time): 332.61W Rig Power (day time): 175.95W
Your night time power looks really good, but still plausible. But I can't imagine how you pulled off that day time power draw. What are the rest of your settings (volts, clocks, etc.)?

I'm jealous of you guys getting 3.XX MH/w and more! Dammit, you're going to make me go buy one of those power-sipping CPUs this weekend

Even being optimistic I don't see how the rig could be bellow 300W with these frequencies and voltage. Something is definitely wrong here.

Even if AC/DC loss was 0 and MB/CPU was 50W. We are talking <130W per 6990? Agreed. Even for me this didn't pass the smell test. I'm looking to add an appliance power meter like this one to get real-time power stats (in Watts so no conversion required) for just the mining rig. Currently the UPS power stats are for the entire rack and I subtract out the current draw for the other components in the rack so the error margin is larger than need be.

That's pretty damn good for a 5770 setup.

PSU : SeaSonic X-1250 MOBO : MSI 890FXA-GD70 CPU : AMD Sempron 145 Sargas
Running BAMT off a USB key...
5 x 5870s 1.000v 825/150 clocks 1875 Mh/s 615W average at the wall... (Varies day/night)
3.05 Mh/W
But I do have a box fan pulling air across the cards and a wireless bridge, so there's another 30w maybe. :/

Depends on the box fan. Mine pulls 70w on the low setting and 110w on the high setting. Best used to move air across 4-6 rigs to reduce the hit on efficiency.

PSU: OCZ 1250W 80 Plus Gold MOBO: Gigabyte GA-EP45-UD3P GPU: 5 x 5870 (ref) @ 950/300, stock V CPU: C2D e8500 Fans: 3
Power @ Wall: ~990W MH/s: ~2150 MH/s per Watt:: ~2.2
Taking clocks down doesn't drop power consumption significantly...
Any idea how much undervolting would do?

5870's react very well to undervolting, however finding the otimal settings can and will take long, each card is an individual. I for one am running two with the following settings (I trust these to be spot on with my miner/kernel and other mining conditions, including electricity price, difficulty, exchange rate...): #1 core 872Mhz, memory 200Mhz, core voltage 1.000 for 376Mhs #2 core 927Mhz, memory 200Mhz, core voltage 1.000 for 395Mhs You can also go as low as 0.95v on 5870's but I havent started tweaking at that voltage yet, propably will when the block reward gets halved.. depending on the exchange rate and difficulty ofc.
