[ANN] profit switching auto-exchanging pool - www.middlecoin.com

[tjc]

I have 2 7970's, 1 7950, and 1 280x on a 1200 gold rated psu. It should handle them no problem, I tried upping the voltage, and I tried it in both the config file and in msi afterburner with no luck

and yes, all in 16x slots - two 7970's directly connected to mobo, and the others on 16x-16x risers

Heterogeneous card configurations almost always sacrifice performance.  Specifically with 3 different types of cards, you're going to be losing at least some hash rate.

Go with Homogeneous card setups (all the same brand and model, preferably the same batch), if you want to really push your machines to the limit.

I've found after a year that pushing my machines to the limit is less productive than a nice stable continuous hash day after day after day. But maybe I suck at this.

Also, I've had a 7970 running at 95-100 degrees for 3 months now. Just waiting for it to fail I guess (others all run mid 70s to 80s).

Is it running that hot in a case with the others? Why dont you add some more cooling and save it?

They are all in here. Cooling is quite good as the rest run close to 80. I'm sure its a failing card or a card issue. I have it underclocked and undervolted and its still hot. Frankly, I don't really think its a problem but we will see.

Looks like a little closet grow setup.

I learned all my cooling tips and tricks from the grow forums. The inline fan was well rated:)

Is there a short cut to find my miner in the list?

Like a way to show wallet from smaller to bigger, 1a to 1z?

step 1. copy your wallet address
step 2. go on middlecoin website
step 4. ctrl + f
step 5. ctrl + v
step 6. ?
step 7. profit

Warning : this question is for coinGeek and is actually about middlecoin.

First : nice work !

Second : have you considered using RRDTool for the graphs ? The gifs would take less space than all the raw datas in the javascript file.
Maybe you are more limited by your CPU than by your bandwidth.

Just want to share my exp.
Burnt one of the PCI-E power cable yesterday, power cable melted and got welded to the PSU for ever 
Not sure of the reason though.
- Might be a faulty PSU/cable (1500W)
- Might have been caused because I tuned by 4 R9 290 connected to it to run at 880 KH/s instead of 825ish it was running at for weeks.

I have good control over temp of cards, nothing goes above 90, usually in their 80s

Not sure yet, back to cgminer setting which gives me 825ish and a new (same brand PSU)
PSU: Silverstone Strider Series 1500 Watt (SST-ST1500)

I want to mine, but keep my house intact as well and not burn it down 
I know this has nothing to do with middlecoin, but just sharing....

Very kind of you, but why in this forum?

I had one of those molex->PCI-E adapter cable melt at the GPU end before. Luckily I could clean it up enough to continue using the GPU with a change of cables.

My cards run to their limit (stock voktage though), they are stable and never get above 78°C, usually high 60's. But then again, I have them in the shed outside where it's nice and cool.

I am still having a huge unexchanged ballance. It's been several days now. Anyone else having this or know how come we are sitting on those coins that long? Is it because the exchange rate of those coins is terrible atm?

not sure why, but I personally am looking forward to the day it gets paid out

Not a clue why, but i've got 10x more than my balance at the moment, will be a nice payday on that hopefully.

I have 5 cards running 600 Khash and 1 running 550.

I have 2 similar machines with 2 cards in each but with different results.

This screenshot is from one of them. As you can see the left card get's 50 Khash more than the other.


30 min later


I normally use GUIminer, but I pasted the command in to CGminer to get this screenshot.

cgminer.exe --scrypt -u 17HjaGvN64UD28NMigjBbu7Ru6kHy26TZi -p 12345 -o stratum+tcp://middlecoin.com:3333 --gpu-platform 0 -d 1 -w 256 -v 1 -I 20 -g 1 -l 1 -T  --thread-concurrency 20992
cgminer.exe --scrypt -u 17HjaGvN64UD28NMigjBbu7Ru6kHy26TZi -p 12345 -o stratum+tcp://middlecoin.com:3333 --gpu-platform 0 -d 0 -w 256 -v 1 -I 18 -g 1 -l 1 -T  --thread-concurrency 20992

Ps. I would love that lovely "green text" and showing both GPU's in 1 console, but I have been unable to get that result out of my CGminer. I both lack the program version and the command line.

Any help would be much appreciated

Please, not in this topic. Ask it directly in the alt mining forum.

[Ioqua]

Koldtoft, why are you running separate instances of cgminer and not just both cards in one instance? or you could run it through CGwatcher

I will try CG watcher. Thank you.

Sorry, my bad I did not know that.

Looking for some help with hardware, fellow middlecoiners.

I'm trying to work out whether I can get away with running 3 x 290's plugged straight into an Asus M5A99FX Pro 2 motherboard. ie without powered risers. My cards currently pull around 320watts each. The 8 pin power connector is rated at 150 watts, the 6 pin is rated at 75 watts, which leaves around 100 watts to be drawn from the motherboard - multiplied by 3. Seems like a lot to ask of it??

The motherrboard is supposedly rated for quad crossfire - it has 2 true 16x slots, and 2 x16 slots in x4 mode.

Am I going to kill it if I plug all 3 cards directly in? I see plenty of posts elsewhere saying "3 is the max number of cards you can run without powered risers", but none of them are talking about running cards that draw as much as a 290. I don't want to fry the board or cause a fire or any other such extreme things

Thanks for any input.

[rudyo]

I wouldn't risk it.  It is always good practice to run powered risers on any GPU, particularly for mining since they will be working at 100% all the time and will be pulling max wattage.  3+ GPU's is a must. You don't want that coming through the PCI from the MB.  

Oh and you would be better to ask this in another forum..not middlecoin

I feel like I'm repeating myself, but please, your question has nothing to do with middlecoin. Please ask somewhere else.

Anyone think alt-coins will go up in value before recent drop? I made like 20-25$ day in december and now its down to 14$?

---------------------------------------------------------------------------------

And h20 really need to do something about user 1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR with hashrate of 639 Mh/s (mining with ASIC)
23 Mh/s increase in less than 24 hours. This is worrying especially if he's making a second "mining plant" with another 600 Mh/s. That means he is going to take 10% OF TOTAL POOL VALUE.

With that hashrate he can go and solo-mine instead on a low difficulty alt-coin.

What actually is wrong with 1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR???

Explain to me why having him on the pool is a bad thing?
