Think it's EU again.  I've just checked and my miners are currently on plain 'ol middlecoin, which is lower in my priority list than EU.

Way too much work. I want another mh I zip tie two more cards onto one of the racks.

Blah blah, include a quote from the guy writing code to mine with CPUs. Oops.

This made me laugh a LOT Cheesy

Sorry I've not replied in a while.  Been putting all your suggestions to good use, and have managed to improve GPU performance a fair bit.

However, having installed another rig, I've hit a new problem...Available power.  In that I'm now tripping the breaker out on my electricity.

I'm going to get this sorted by having another mains feed installed, but in the mean time, I'd like to change the config of my rigs to drop the power usage, while still giving best hashrate possible.  In otherwords the most efficient power to hash ratio.

Any thoughts on the best way to achieve this?  Wans't sure whether to just drop intensity, or maybe GPU or memclock settings.  Bear in mind I'm using Ubuntu, and don't fancy tackling undervolting yet.

Each rig is currently pulling 980w at the wall, I'd like to get it down to around 700 short term if possible.

Thanks in advance for any suggestions.

Is anyone else getting very high rejects lately? Enough to see yellow on the graph. Been getting up to 10% for some reason, restarted the machine even and still seems the same. I would think maybe it's a coin we are mining but another miner on the same asia server isn't getting this.

http://www.middlecoin.com/reports/1NU2JCAyTN3bf3TxGGfPHVufEn4YXpX1Qe.html

3.3% rejects on the EU server for me, which is less than 0.5% above what I typically see.

So our top miner is hashing at over 800 MH/s. That's between 1200-1250  7950 GPUs. I would be interested to know how he/she is doing this. Data center would be too expensive unless he/she owns it.

1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR   817.4512   29.9939   0.41629816   5.19880948   4.04748705

FYI has probably been discussed 10 times in the last 20-30 pages

So have we lost all our hash power today or did the mining stats just loose track of them? Hopefully our payouts aren't affected right?

Well at the moment it looks like we lost all of today's mining which would be a shame, hopefully this is just the delay in the database.

What's lost? My unexchanged jumped WAY up. Draw a line across the top of the points, it's where it should be.

ditto for me...If anything my broken graph unexchanged balance has curved up a bit.

I got a bunch of PowerColor R9 290 cards, and noticed they run best at a engine/mem ratio of ~0.74. You could probably get higher than 800 if you kept that ratio, but overclocked a little bit.

All my settings run at Powertune @ +20
1105/1500 gets me 855
1075/1450 gets me 835
1050/1400 gets me 810
1025/1350 gets me 795

I would love to run them at 850+ each, but the temps are too high for my liking right now, so I have to downclock. We're going to move them in a couple of weeks and install some more AC units. Hopefully between that and 2 weeks of burn in will allow us to overclock even further.

Quick question....Is this at stock voltage?
Yes, stock voltage. I'm in linux, so I can't adjust that at all.

Thanks for confirming, wanted to check as I'm on Ubuntu too, and while it's theoretically possibly to change firmware and change voltage, it's something I'd rather avoid.

One thing that did occur to me once I'd found a happy setting last night, is whether the extra 30watts per card is likely to have a negative effect on the mother board.  This rig is cased up for numerous reasons, so I'm not using powered risers...It's a decent 1300w EVGA PSU so I have no concern with the PSU itself as at most the system is pulling around 1050w at the wall.  I gather 6 pin power is rated at 75w and 8 pin at 150w, but wasn't sure whether "rated" meant "maximum" or whether a decent PSU would supply more, or whether anything over 225w will definitely be coming from the motherboard?

So far the system seems happy, but it was just something I curious about:

So for now I've settled on powertune20 1025/1350

At this point, I have two questions...

- Based on my cgminer.conf, is it normal that my wall usage and WU dropped when I turned on powertune without increasing clocks?

- Am I right in thinking that WU is ultimately more important than hashrate?  So if hashrate goes up a bit, but WU drops, that's worse right?  Just checking the things I've read previously are correct?

thanks again all.....

The first thing that you have to do is to force gpus at a specific Powertune level. You won't hurt the cards, you will just draw some more power. Some cards are more efficient the the others at powertune level 0, but when you rise powertune to 10 or 20 the get equal. So, first thing to do is:

"gpu-powertune" : "10,10,10",

see what happens, then try also

"gpu-powertune" : "20,20,20",

And don't be afraid to do some overclocking ... E=1000 and M=1500 should run just fine at 880 kh/s.

Noted, I'll have a play with the powertune some more tonight.  I did dabble with it a little early days when setting these rigs up, but decided not to set powertune till I had a reliable baseline.

Regarding E and M, again I did play a little, and I found I could get the XFX cards up around 875-900khash each, but while I wasn't getting any noticeable HW errors etc. I did see the WU value either not really increasing, or perhaps even decreasing a touch.  That, combined with a couple of forum threads suggesting the R9 290 struggles to push WU up despite khash increase when you increase these, caused me to leave near stock initially.

Thanks.

Performance difference from one brand of reference r9 290 to another?
by

on 09/01/2014, 13:07:26 UTC
Hi All,

Did some searching, couldn't find anything specific so thought I'd ask.

I have 2 rigs, both 3 x r9 290.  Both have identical CPU, mobo, RAM, PSU same version of Ubuntu, same version of drivers, hardware all purchased at the same time...You get the idea...

The only difference is one rig's 290's are XFX, and the others are VTX3D.

Machines are sat near to each other (so environment is essentially the same), and both mining the same pool(s)....Yet I'm seeing roughly a 10% drop in performance on the VTX system compared to the XFX (measured this over a number of days so enough time for fluctuations to average out)....  I thought all reference cards were the same, was wondering if I'm missing something?  I even copied the cgminer.conf from one system to the other, so even that's identical.

Was hoping someone could shed a little light on this??  Thanks in advance for any thoughts...

P.S I'm aware I'm not pushing the cards quite as hard as I could, but I wanted to stay at roughly stock clock and mem till I'm really comfortable with the setup(s).

Also, this analysis is fundamentally flawed because mining is time-dependent. Run the miners on 6 new addresses for several days (STARTING AT THE SAME TIME) and compare those graphs. That would tell you a lot more.

The graphs are from six different miners taken at the same time. I can understand that not knowing who was mining where is a flaw in the analysis (although, why should WE be choosing where to mine @ middlecoin in the first place).

But I don't understand your reference to their timing? If the graphs are showing the same time period and you can see the begin & end situation of each miner..

You're right, under normal circumstances, *we* shouldn't have to choose where to mine, but my interpretation of what I've read in the last 20 or so pages is that h20 and co have had some growing pains (5000MHash increase last 7 days by the looks of it, for example, and steeper in previous couple of weeks I think) that have resulted in some stop-gap solutions on some servers (EU server was constantly on one coin for a while I think)...

Be interesting to see the results of another selection of miners once all the new servers are out of "beta" etc.

no rush, this coin will hold long term. dont worry about it

Agree...

I'm fairly new to Crypto mining, and I just don't get the rush everyone seems to be in.  Every new coin, some people invest maybe a few hours of hashtime into it, and then talk about selling it off like it's the most important thing in their world.  Surely if the coin does in fact tank then OK, you've lost the chance to make a few quid, but if it recovers and goes onto do well, the medium to long term can be much more lucrative, right?

I mined a few thousand NYAN last night, total electric cost was maybe 1 pound.  Not something I see as a huge investment at this early stage and something I'm more than happy to sit on for a while Smiley

I'm assuming there's lots of others that think like this, they're just not the ones constantly posting "OMG MUST SELL NOW TO GET MY 0.001BTC OR LIFE IS OVER"
