AMD OpenCL Momentum miner

[Darkbane]

running 6 gpu on one motherboard is very easy to burn your ATX connector on mother board since each pcie slot will draw 75w from motherboard. if you want to put more than 4 cards on same motherboard ,you need to use powered riser for pcie

I am using powered risers... they are the USB style with the nice molex on the little board that comes with it... you can also get a PSU like the AXi series from corsair and monitor what each power cord does for each GPU or other connection... its neat... you'll soon see you draw a lot less from PCIe slots than you think on average, most of the power goes through that little cord plugged into the GPU... some GPU's from sapphire now come with two 8pin plugs so almost all power goes through the PSU direct...

I have a question for NaN about this but in a different light.
Since we can start two threads on our GPUs (those that can)
would it be possible to mine at Ypool and Beeeeer at the same
time by running clpts-v0.1.x as one thread on all the GPUs and
then clots-v.02.x as one thread on all the GPUs. I would think
it's possible though you'd be mining half speed to each pool BUT
you'd be covering both bases at the same time. Just an idea/thought
that came to mind.... please, no flames :-)

question to the developer:

what about a back-up-pool-solution
now i'm awake and it is possible to change the beeeeeer-pool to ypool
but it is a problem when i'm not on

maybe there could be a switch after 2 mins without work at one pool - then the miner changes the pool
it is only a bit longer path to set like in cgminer to have the back-up-pools

the big work is not to set the bat-line, but to code this functionally

I'm working on it. But this requires some development time because I have to join multiple code branches and my implementation of the xpt protocol v5 is still not working. If there is a beta available I will announce it.

Now THAT is quite the find! I can't wait to give that a shot when I get home as well!
Right now my solution is to run cgminer in a shell in which I immediately disable all
the GPU's by hand (haven't figured out a way to do that in a cgminer.conf). This allows
me to monitor GPU temps and FAN speeds... plus have control over other GPU parameters
if I want, but again this is mostly to monitor. The cgminer.conf I run when I start cgminer
has all my tweaks. Just thought I'd pass this out as a work around, albeit a little messy.

Edit: I found this http://sourceforge.net/projects/amdovdrvctrl/?source=navbar, I'll give it a try once I get home. It was last update Dec 13 2013.

hi all, how can I fix this?

Obviously, the miner cannot connect to ypool.net. Is your internet connection OK?

Has anyone successfully set the GPU voltage using cgminer under linux for a R9 290(X)?
I have my gpu clock, memory, and fan settings where I want them to be but I wouldn't
mind under-volting the GPU to save a little energy and heat. I *believe* cgminer wants
an exact voltage and not a delta but I could be wrong. I don't know what the normal
voltage is for a R9 290 and every attempt to enter an absolute value like 1.25 fails (out
of boundary). Many thanks in advance!

I have been in that same situation for the last two days. I found some good clocks that provide a rather good performance boost in-terms of c/m. I have my 290X's running at 1150/1150. The core increase raised my c/m by ~400, the problem is that I am having some heating issues (80C - 85C - 90C spikes)...I'll try to figure out a way to undervolt on linux, I'll post my solution here if I find anything. If you find something please share.

At the moment I have multiple .sh files that I execute after a system reboot. One sets the fan speed to 100%, and then overclocks my GPUs, one to initialize the miner, and the last one to monitor temps.

three his 280x ,win7 13.1dirver.just get 57xx, it's too bad. use -t 0,0,1,1,2,2 .
 if add -a 1, the miner can not run. 
so, help me!

Which version do you use? I guess that you're using an old one. Use v0.1.4 or v0.2.2. If your monitor is attached to GPU 0, then I would use -t 0,1,1,2,2 and I would try -t 0,1,2 too. -a 1 should be fastest.

Hello NaN, I thought 0,1,2.... is the number of card ? because for 4 card i use 0,1,2,3.
What exactly is his number? eg for a single card I put t 0? it would change something to put 0,1,2 for a single card?

The numbers after -t are the DeviceIDs, which are shown during startup (DeviceID x). For each number in the list the miner starts one thread. Normally, the first GPU has DeviceID 0 so that -t 0 mines with one thread on the first card and -t 1 means that the miner uses one thread on the second card, etc. Thus, -t 2,2 means that the miner should launch two threads on the third GPU. It might increase your performance but at least the Windows driver of R9 290(X) seems to be broken and only the Linux driver functions with full speed. Just try whether  -t 0,1,1,2,2,3,3 or -t 0,1,2,3 give you better performance if you are using four GPUs.

thank you NaN for the explicatio, when i try -t 0,1,1,2,2,3,3 i dont know why but i have invalid password or usernam worker.

I have beter result with version x86 that x64, i have windows 64 bits.

Yes the idea is good. But you get them cheaper on Ebay. Plain regular risers or USB3.0 ones that are very nice in terms of use of space.

If you buy the ASRock H81 BTC mobo you don't need powered risers as the mobo has 2 4 pin molex connectors you can connect the PSU to so the extra 75W comes from them.



For the Linux users; is it possible to run more than 5 cards there? Win8 has a max of 5 and only for the HD79** series there is a custom driver available to run 6.

So tinkering around with clpts... I was wondering... can you run six gpu's on windows, since everyone says its almost impossible without heavy modifications to windows and/or the drivers...

since I see a lot of fuss over people being able to run five with difficulty, and so many have to use some weird trick or tip to get six to work... so I ran to a friends, borrowed two video cards, and now I have an answer!

yes you can run six gpu's on windows 8.1 64bit...

I didn't need to do anything fancy for windows... hooked up to the risers and turned it on... came up right away...

Now I should mention, it was more challenging to get the BIOS to recognize all six cards, than windows... I had to disable several things in the BIOS, change all the pcie 16x slots to pcie 1x... and of course disable the onboard graphics (which I actually had been using since it was nice to mine full bore on the cards and use the onboard for daily work with no flickering).

my friend just called and asked when I'll have the cards back, I wish this was like borrowing a garden hose and he'd forget... he doesn't want to go all night without full mining, the sickness we all share!

I think the reason this was so easy, they were all the same GPU chipset, the pitcairn, a mix of 270 and 270X cards... I now wish I had a 7th one to test and see if I could get all seven to work together at once... I think this is the reason I love coin mining, its just one big hobby to tinker around with things and see what you can do.

Would these risers work?

I am getting an error when trying to run this miner.

Are the files gpuhash_x in the same directory as the binary? I guess that the application cannot find the file.

you are right, I had to cd to the directory as the binary before it started working. Thanks.

Now I get a different error:
