Title: Measured at the wall, what's your Watt/MHps Post by: Fjordbit on July 20, 2011, 04:23:04 PM By my Killawatt, I'm running at 530 Watts for 800 MHps. Is this reasonable, or is this out of wack? Title: Re: Measured at the wall, what's your Watt/MHps Post by: Xephan on July 20, 2011, 04:26:50 PM By my Killawatt, I'm running at 530 Watts for 800 MHps. Is this reasonable, or is this out of wack? Hard to say without knowing key components of your config esp GPUs, CPUs and PSU. For example if you're doing 800MHps on 530W using purely CPU mining, it's astonishingly good ;) For what's it's worth I'm pulling 465W or so on a 80+ Silver PSU for 780MH/s, including 1 out of 3 core heavily loaded due to the bugged Catalyst 11.6B drivers. And 470~474W for 800MH/s Edit: Those numbers were off by a bit as I had my meter on VA. Actual watts is 433W and 439W. Title: Re: Measured at the wall, what's your Watt/MHps Post by: Smalleyster on July 20, 2011, 04:41:58 PM This is a great thread as it deals with the only two paramaters that really matter in the long run.
What is your input to output ratio? The other factor is capital (what is your rig, what did it cost, how did you set it...) but that is realy just how you got started. I hope this thread gets lots of responses. Title: Re: Measured at the wall, what's your Watt/MHps Post by: teukon on July 20, 2011, 06:12:08 PM I'm getting 723 MH/s from 300W (2.41 MH/J) but I spent extra on a good PSU and on aftermarket coolers for my two cards.
530W for 800 Mh/s seems a little high but not grossly so. I have a friend with a 6990 managing 800 MH/s at 520W and he's perfectly happy with this. I'd guess you are overvolting your cards and if so and you can stomach coming down to 750 MH/s you might save 50+ watts by lowering the clocks and voltages on the cards. Title: Re: Measured at the wall, what's your Watt/MHps Post by: cicada on July 20, 2011, 06:46:40 PM 2 6950x2 rigs getting 720MH @ 410W each, so 1.4GH for ~820W
I've also got a pair of 5830's in my Opteron server, for 540MH @ 530W - obviously this is a poor ratio, but pre-mining I was living with the server pulling 200W on it's own so I'm OK with these numbers. Looks like I've got some optimizing to do ;) Title: Re: Measured at the wall, what's your Watt/MHps Post by: bmgjet on July 21, 2011, 01:24:23 AM 280-290W at the wall.

Title: Re: Measured at the wall, what's your Watt/MHps Post by: Fjordbit on July 21, 2011, 04:26:47 PM Hard to say without knowing key components of your config esp GPUs, CPUs and PSU. For example if you're doing 800MHps on 530W using purely CPU mining, it's astonishingly good ;) I think Smalleyster has the right idea on the spirit of this question. It's more of an idea of how efficient rigs can be or should be using these the two variables of input to output as a comparison. The point isn't to think of how good the hashrate is but how good the ratio is. It does seem like I'm on the low side, but not way out of range. One thing that this ratio will give you is resilience to difficulty rises and/or btc value drops. The higher the ratio, the longer you can mine and remain profitable. Of course electrical rates matter here too.

One thing that this ratio will give you is resilience to difficulty rises and/or btc value drops. The higher the ratio, the longer you can mine and remain profitable. Of course electrical rates matter here too. Agreed, but knowing this ratio is not as helpful if we did post the config. Like in my absurd example, ratio might seem low but is actually extremely efficient for the kind of equipment (purely CPU) mining. In your real case for example, while it may be low, the important thing is why? Imagine if somebody decided it was not worthwhile doing this because his efficiency was just too poor for long term... and the problem might actually just be the fact he's using an old crap $30 PSU with 60% efficiency which could had been fixed by a simple $50 purchase. With the additional details, everybody will get a better idea where they stand :D Title: Re: Measured at the wall, what's your Watt/MHps Post by: Smalleyster on July 21, 2011, 09:27:17 PM Ok so the quick and dirty analysis so far:
Watts Mhps Watts/Mhps Mhps/Watt 530 800 0.663 1.509 433 780 0.555 1.801 439 800 0.549 1.822 300 723 0.415 2.410 520 800 0.650 1.538 820 1400 0.586 1.707 285 281 1.014 0.986 372 614 0.606 1.651 574 824 0.697 1.436 Average: 0.637 1.651 I think the most telling ratio here is that one can generally expect about 1.7 Mhps per 1 Watt of power input. The 2.4 and .9 seem to be "Flyers" or "Outliers". Removing them gives us an average of 1.638 which is not a significant change to a rounded 1.6. Rule of thumb: expect just over 1 1/2 Mhps for every 1 Watt of power used. Thanks for the data guys, that was fun. 8^) Title: Re: Measured at the wall, what's your Watt/MHps Post by: cicada on July 21, 2011, 09:31:45 PM Hooray, I'm average!

I had hoped to have all types of measurements so people could really see the top, bottom and middle ground. That's understandable, you can go ahead and leave it in if you wish. Perhaps there should be some context for the numbers added, but this could get really cumbersome. For example, that 540MH / 530W setup is: 2x 5830's @ 270MH/card, clocks 875/1000mhz gpu/ram 6x 1TB HDDs (most are 'low power' versions) 1x Opteron 6128 ( 8 cores @ 2.0ghz each ) 4x 4GB DDR3-1333 RAM 4x 120MM 2400+ RPM fans, 4x 60MM high-flow fans lined up in the card gap Corsair HX650 80+ Bronze 650W 'professional series' Certainly some highly-pertinent information can be gleaned from there, such as the ~200W for that base system, but doing so could quickly become really tedious ;) Title: Re: Measured at the wall, what's your Watt/MHps Post by: Smalleyster on July 24, 2011, 06:08:41 PM Certainly some highly-pertinent information can be gleaned from there, such as the ~200W for that base system, but doing so could quickly become really tedious ;) In the spirit of keeping things as simple/readabel as possible I just added "NOT JUST MINING" to the front of your Rig descriotion. Is that an apropriate "fix"? I thought that putting the Member's name/handle would allow those who wanted more information the ability to go look up further details. And again thanks to all for contributing such valuable data to allow us to glean some actual information. We now have 18 data points and that means to me that we are just starting to become "statistically significant". 8^) Title: Re: Measured at the wall, what's your Watt/MHps Post by: johnyj on July 26, 2011, 10:26:28 AM The most important factor is free electricity 8)
