Title: Post Your Mining Rig Efficiency Post by: Mousepotato on April 10, 2012, 03:56:10 AM 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. GPU: 2x 5970 @ 625/150MHz @ 899mv MH/s: 1128 At the plug: 394W 2.86 MH/w Whoa, I think I finally beat D&T!!! Except now he has a bunch of BFL Singles :D Edit: New numbers after adding another 5970: GPU: 3x 5970 @ 625/150MHz @ 899mv MH/s: 1690 At the plug: 554W 3.05 MH/w Title: Re: Post Your Mining Rig Efficiency Post by: rograz on April 10, 2012, 06:20:33 AM best rig i've got

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/w Whoa, I think I finally beat D&T!!!

Title: Re: Post Your Mining Rig Efficiency Post by: Mousepotato on April 10, 2012, 06:51:09 AM 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.

Except now he has a bunch of BFL Singles :D 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. Title: Re: Post Your Mining Rig Efficiency Post by: JinTu on April 11, 2012, 12:53:05 AM 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.

What is your power draw at idle before you start mining? Title: Re: Post Your Mining Rig Efficiency Post by: rograz on April 25, 2012, 06:35:20 AM Around 170W
Title: Re: Post Your Mining Rig Efficiency Post by: Mousepotato on April 25, 2012, 06:56:05 AM 170W is really good for that many cards. What other components are you using? CPU/memory/drive?
Title: Re: Post Your Mining Rig Efficiency Post by: rograz on April 25, 2012, 07:21:06 AM c2d@800Mhz 0,9V, Some old MSI x48 Platinum something motherboard that is undervolted quite a bit for chipset etc, 1 stick of DDR3@1,1V and a WD Green 500GB. Beats my other rigs quite a bit for cpu/motherboard power usage. with just 1 card it's below 80W idle and that's just crazy considering the efficiency for the PSU at those low loads or the HX850 is simply really good even at low loads.
My other two 6 card setups aren't nearly as impressive for board/cpu. Got one Gigabyte GA-990FXA-UD5 with a sempron that sits at around 110W idle with one card and a x58 motherboard that is around 100w with just one. Think it has to do with the sapphire xtremes as well though, they draw around 3-5W less than your normal 5850/5870 ref board at idle. Or I should say the first revision of the cards does (6 pin connectors at the back of the card, later revision had them on the side of the card) the later revision is worse iirc, also got shittier VRMs for undervolting (no GPU registers in bios).

D&T, what clocks are you running to get 3.2G out of 4x5970. ? High. :) They are water cooled. Each card is clocked differently because once you remove the heat each GPUs individual ASIC quality starts becoming the performance bottleneck. They average ~860 but no two GPU is clocked the same. Most are in the range of 830 to 875 range. I have found you can't get past 900Mhz and keep them stable. I think the 3 phase VRM (5870 uses 4 phase) just can't handle it. I do have some lagards though. I have some which can't get above 800 even cooled to <40C. I have two cards which I think have a bad VRM because 1 of the 2 GPUs can't go above 700. :( Of the 48 GPUs I had one simply die when I watercooled it. Explain that? Maybe I pushed it too hard and without excessive heat to throttle it back it killed itself. It had been flaky prior to watercooling it though. I think I am going to remove the waterblock and just use the remaining core for gaming. Due to the luck of the draw not all the rigs hit 3.2 GH/s. Of the 5 rigs they are 3.22 GH/s, 3.20 GH/s, 3.15 GH/s, 3.08 GH/s, 3.01 GH/s. I got one more rig to convert. I am hoping it is a 3.3 GH/s+. The 3.08 and 3.01 likely could be pushed a little harder but building the watercooled server rack was a lot of work so I am happy they are just stable right now. Ironically I am now kinda "over" mining. I am moving on to other things hopefully they just mine away for a long time.

Beats my other rigs quite a bit for cpu/motherboard power usage. with just 1 card it's below 80W idle and that's just crazy considering the efficiency for the PSU at those low loads or the HX850 is simply really good even at low loads. My other two 6 card setups aren't nearly as impressive for board/cpu. Got one Gigabyte GA-990FXA-UD5 with a sempron that sits at around 110W idle with one card and a x58 motherboard that is around 100w with just one. Think it has to do with the sapphire xtremes as well though, they draw around 3-5W less than your normal 5850/5870 ref board at idle. Or I should say the first revision of the cards does (6 pin connectors at the back of the card, later revision had them on the side of the card) the later revision is worse iirc, also got shittier VRMs for undervolting (no GPU registers in bios). rograz, how are you volting your 5850/70s below 0.95? I'm not sure any of my non-reference cards are capable of doing this, but I haven't been able to find any info on how to do it. I run Linux, and I think that Radeonvolt might do it, but this only works for reference 5850s. I've got some extremes with the pins on the side, so I guess those are out, but I've also got some non-extremes with the pins at the back. Any insight/direction on this would be appreciated.

Title: Re: Post Your Mining Rig Efficiency Post by: gyverlb on May 21, 2012, 06:03:41 PM Can't seem to undervolt my Sapphire 7970 :-[
The voltage goes down if I reduce the GPU frequency but is locked at a fixed value given a frequency. Here's what I found reported by cgminer : 150->300MHz : 0.8V 301->450MHz : 0.85V 451->600MHz : 0.9V 601->700MHz : 0,95V 701+MHz : 1,17V So anything above 700MHz drops the efficiency dramatically (and this thing overclocks like there's no tomorrow...). I use the 2.4 Linux drivers, anyone knows any way to circumvent this limitation ?

Almost everyone in here is posting (total product gained / total cost of obtaining product), which, in your annalogy, would be wpm/$. 200wpm/$20 (one uber typist) is 10wpm/$. 400wpm/$20 (4 typist at same money) gets you 20wpm/$. Second is more efficient, AND gets you more money. See the correlation? The two are the same. In our case, we're dealing with MHs/W, instead of wpm/$. Also, 10 apples are better than 1. Yes. However, buying 10 apples per $ is more cost EFFICIENT than 1 apple per $, which is exactly what mining efficiency is all about. |
