[ANN] MMC.1GH.COM - GPU mining, CPU mining ★

[earthbound]

6xxx series seem to behave like this: return not doing any actual work and not returning error code. Unfortunately I have no such card or access to one to debug this. Is this in Windows, and if yes, could you try in Ubuntu (you can boot liveusb to not disturb your main system)?

I'll give that a try and let you know.

[Edit: yes this is on Windows.]

I installed Ubuntu Linux (dual boot with Windows), and both before and after I install the ATI proprietary drivers, I get this:

Code: [Select]

root@COMPY:/home/genericUser1/Downloads/mc2-1gh-lin-x64# ./mmc-miner MX1v3iwF5DxZutY8WPVotyVeeUu1vQV17W
Skipping device 0 (Turks): GLOBAL_MEM_SIZE 1073741824 < required 1677721600
Skipping device 1 (Turks): GLOBAL_MEM_SIZE 1073741824 < required 1677721600
Skipping device 2 [CPU, not a GPU]
No suitable devices found. Only AMD cards with 1.5G+ available RAM supported on the moment.
(1073741824 bytes = 1GB.)

The package for the cards, at least, says they have 2GB onboard memory. What am I missing? Linux newbie, here . . . how do I get the full memory recognized by Ubuntu and/or this miner?

when I go to the 1gh website to see how my GPU miners are doing I realised that I am mining at 40 hpm but I have 0 unconfirmed Memory coins. Then again I have been only mining for 20 minutes.

Any suggestions?

The pool is RBPPS, please wait for a block to be found to get credited.

Well, I can confirm it's not working on Cayman arch's very well.  My 6970 is getting nothing but rejects, whilst my 7950 TF3's are speeding along beside it on the same board.   

Anyone know offhand what the command prompt syntax in Windoze is for disabling that gpu?  The readme isn't quite explicit enough in that regard. Thanks

Just enumerate device numbers you want to mine on (X in Worker:X string) after your address on the commandline, space-separated.

so I have an amd 6850 and it says that no suitable devices were found
I have 8 GB of RAM

The 6850 has only 1GB GDDR5 graphic card memory which is not enough. I have the same problem with my old 7750

ooohhhh ok haha thanks

Does the Gpu mining requires the system memory?
My 7950 has 3G mem,But my system has only 1G of memory,Will this gonna be work?

Just noticed the top miner has 5000 HPM!

Either he has some big rigs or quite a botnet.

Or maybe aws gpu cloud

I tried to point the cpu miner at this pool, but I'm getting connection errors

Code: [Select]

HTTP request failed: necessary data rewind wasn't possible
json_rpc_call failed,
Have I got the wrong address?

Code: [Select]

./minerd --url http://mmcpool.1gh.com

It's on port 8080

I have two R9 290s on a 1000 watt power supply that was mining script for over a month.  Why does my video card make a chirp noise when I run the GPU miner.  I tried it on one GPU only same problem.  The temperatures are way lower with this GPU miner than with scrypt.  Any suggestions?

Thanks

The miner's algorithm puts the load on card unevenly, there are spikes when power consumption is maxed out followed by a lower consumption intervals. Hissing sounds happen during these spikes, power lines throttles make them when the current changes sharply.

It is called a coil whine. It happens because scrypt does not stress the VRM's on the card like this does, you may need to up the volts or get a PSU with less power wobble. It is perfectly normal to hear this on cards when being pushed hard.
