Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 336. (Read 5805537 times)

I am pretty sure dollar for performance the 7950's are one of the best going. However if you can only have 1 gpu the 7990 would be the king.

I am considering ordering one GPU card to replace or add to existing 2400 HD card in my Dell desktop.
I want to use it for scrypt mining (Litecoins, Feathercoins..) Which card would be the best one to get? (I can spend up to $1000) on one card that would be best for the job. Any recommendations?

This is the card I have in my desktop already and I want to do some litecoin and feathercoin mining..

HD5xxx or better for mining. You might be able to get some miner to run on it but why?

Can I use a different miner software or is ATI Radeon 2400 HD Pro not usable for mining at all?

That GPU is not supported.

Hello,
Having troubles with cgminer on my Debian machine. I have ATI Radeon 2400 HD PRO and I installed drivers from the manufacturer and OpenCL drivers too.

I have a question about the API:

The values returned for MHash/s Average on the "summary" and "devs" API calls are not very usable when scrypt mining.

It would be great if the API would return these values with higher precision, like to the 5th decimal place. Is that possible? I guess I could make the changes myself if somebody would point me to the right file(s), so I won't have to read through the whole codebase.

Any help would be appreciated.

nope, not scrypt, diablo...btc mining

Don't specify a kernel at all.

Have a question. I am playing around with the LTC mining again. When mining on a 7770  when I start CGMiner it tells me

cgminer.exe -T --scrypt --shaders 640
 --kernel: Cannot use sha256 kernel with scrypt


In my cgminer config kernel is set to scrypt. Looked in the Scrypt read me and didn't see anything. I am probably making so silly error I am just not seeing.

well, if that's the case i'll stick to guiminer for the gpu and just use cgminer for the usb guys when they get here.

I use GUIMiner in my work PC for running a Quadro 600 and a HD7750.  Could never get cgminer to play ball with the two different types of card.

so, in prepartion for the pending arrival of ASICMINER usb miners, i was finally switching over to cgminer.

this has been unsuccessful...

i have both an amd radeon 6870 AND an nvidia geforce 560 in my system. i want to just use the amd card to mine, but i can't get that working.

i've got a pool (ozcoin) set up in the config file, and nothing else. on startup, cgminer throws an error talking about ADL and CL devices not matching. after reading through the gpu-faq, the cloest to a solution i found was to use the --gpu-platform attribute. well, i tried that, with numbers 1, 2 and 0. 0's the nvidia, 1 SHOULD be the amd, but is only getting maybe 5 mhash, where in guiminer it's 270.

any ideas? or am i being stupid and missing something obvious? note: running windows 7.

here's the output when i run cgminer with -n

Windows 7 x64 Pro
AMD FX8320
Asus SABERTOOTH 990FX
HD7850 (Asus)
HD6970 (Powercolor)
HD5870 (Powercolor)

When I try and run CGMiner, it just brings up the "CGMINER.EXE has stopped working.

I've also tried GUIMiner, it just starts and quits. (Not a problem for this thread, but thought it might be worth throwing out there too).

I've tried 12.10 drivers, I've tried 13.4 drivers.  Neither make any odds.

I've cleared out all the .ini and config files out of the profile, etc, and re-downloaded a fresh version of cgminer (3.1.1).

I was able to Scrypt mine with the 13.4 miners using Reaper, but in trying to solve the CGMiner issues, now it won't even run.  All the cards ran OK using cgminer in a different machine, but not all at the same time (it was a uATX Celeron machine).

Any ideas?

Work from a pool can't go to a different pool.
On the line that says BLOCK! it will have the front of the hash like 00000123
If that is the network block at the time you got it then yep it made it back to the pool.
If not, then nope it was either an orphan or didn't make it back to the pool it came from.

It's printed  "BLOCK!" before or after share submission?  Because I saw "BLOCK!", and after "stratum disconnect lost ..."
Can cgminer send the found block to failover pool, or disapears?

Im having a problem with an installation on Debian. The cards are HD5870 and HD5970 cards. Normally I work with HD7950 cards and never see these obscure problems with older cards. I removed the HD5970 so now only have HD5870's installed while testing.

I have installed 32 bit Open CL drivers and also compiled CgMiner 32 bit version for scrypt but I keep getting these errors. Cgminer compiled for bitcoin works ok on this machine but Im having a major issue getting Litecoin to work.

Any advice would be very useful. I have tried various SDK's and drivers with no joy.

Sorry, not having a go at you about any of this, but it is very complicated to get things working.

Also, this same rig - the 7970 is happy with a TC of 8192. Anything more and it throws HW errors.

The 7950 can take all the way up to 24,000. Its happy at 16384.

Why such a large difference for the same type of card?

Yes, scrypt. and I have tried so many settings that my eyes bled. Low difficulty, different TC, lookup gap, threads, etc.

I have tried millions of combinations. Then I started to change bioses, and drivers.

Some worked, some don't.

Right now I have a machine with 1 x 7970, and 1 x 7950, and the 7950 likes to die after about an hour of hashing happily at no matter what clock.

If you try to restart, it sprays out hardware errors until a reboot.
