Hi,

Are there any flags I can add to the .bat file to maximise hpm for my 7950? Sorry if this is a nooby question.

Short answer - no. You can only try overclocking, but the algorithm is not tunable by its design.

Thanks for the quick response. Does the algorithm favor memory clock speed?

[Trokhon]

could you add an option to control the vents rotation on card

thanks in advance

my 290 run at 94 degree celcius normally with scryt and fan mangement  I run them at 76

Guys,

it appears that 5xxx and 6xxx series do not work with the miner, please do not waste your time trying it. I am looking into the problem, hopefully it can be solved, but no promises yet.

That would be spectacular!

I'm also getting rpc: rejected on my 6990. tried running it for 1000 rounds+ with all rejects:

Thanks for your replay but it’s still not working ,just one 6950s,same error...

Well, you were asking about the syntax to disable using 6950, so it is like this - you just put numbers of all devices you want to mine on. The 6950 will not work with current miner unfortunately, I am looking into that.

[gerrypp]

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.

As you said i input device numbers 1002-6719(Cayman)  still rejects...

Would you please post a sample output? 1002 is a strange number, they are enumerated from zero, you don't have 1000 cards in your system, do you?

I was wrong？

So, your devices 0 and 1 are not suitable for MMC, you have to start miner like this if you have 3 7950s in this system:

Code: [Select]

mmc-miner YOUR-ADDRESS 2 3 4

May I also ask you to post (or PM) the output of clinfo command for your Cayman?

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?

Would you please try to start the miner like this:

Code: [Select]

GPU_MAX_ALLOC_PERCENT=100 GPU_MAX_HEAP_SIZE=100 ./mmc-miner YOUR-ADDRESS

Looks like I have a typo in my code and set 'GPU_MAX_HEAP_SIZE ' (with a space on the end), which works for Windows, but not for Linux.
