has anyone managed to set up AMD 6970 cards for mining? They have 2GB of memory, but benchmarking "ethminer -G -M" gives an error: Allocating/mapping single buffer failed with: clCreateBuffer(-61). GPU can't allocate the DAG in a single chunk. Bailing.
I'm on Linux with ati-drivers-15.9-r1, OpenCL 1.2 AMD-APP (1800.11). These variables didn't help to solve the issue: GPU_SINGLE_ALLOC_PERCENT=100 GPU_USE_SYNC_OBJECTS=1 GPU_MAX_ALLOC_PERCENT=99 GPU_MAX_HEAP_SIZE=99
win 10 in nanopool i have 4 rigs all overclocked 1. r9 295x2 and r9 290 88 mhs 2. 2x r9 280 44mhs 3. r9 290 29 mhs/bricked now 4. r9 270x 14 mhs with old drivers / new drivers 13mhs going ro build a new rig with 3-6 r7 260x's what's the hashrate on a r7 260x?

Download 14.7 v3 beta drivers, it helped me with R9 270 & R9 270X memory allocation problem (Allocating/mapping single buffer failed with: clCreateBuffer(-61). GPU can't allocate the DAG in a single chunk. Bailing.). It might help you, try it out and share the results.
Hey I think I fixed it. The problem was that I changed the name of the Rigs lastnight meaning I switched the numbers around because they were numbered wrong I just changed it back and I notice the shares are counting again... )
Can you share driver/settings/config for R9 270X. I had 16.1 MH/s with 15.2 drivers (1125/1500 gpu/mem) but since i switched to 14.7 beta v3 i am getting something like 15.4 MH/s on the same card but have to use that driver since i didn't found any other solution after the problem with allocating DAG *the one mentioned above.

My temps were at 88degrees C fan speed was 60 at night when i opend windows and 72 at day hashrate was good 28 to 29mhs 1150/1200. Fuck yes it was loud as hell i couldn't stand it more than a week then i bought kraken g 10 and thermateke water3 now it's at 65degrees C and i almost can't hear it. Yeah buy it if you can watercool it with kraken or custom loop else i wouldnt even concider then you should pay 30 bucks more and buy a custom cooler. Even if i underclocked the card(21 mhs) fan speed would go down by 5 or so and it was still loud

heavy overclocking and great result. What is your electricity consumption (TDP) per card ?
Thanks mate! Its around 300w (250~350), I am using Corsair i series PSU so I can track the power usage on the PC directly. I am not measuring at the wall yet.
I need to underclock the voltage for better efficiency, am trying to see if there is a way to do it on the Gigabyte card without needing to flash the BIOS. Any ideas are welcome...

thanks. i just bought the card. the seller repriced it to $185 i'll try it later

I call bvllsh1t on this. There have probably been about a hundred people before you with a 390 and the highest they got was like 32-33MH.
Same core and memclock as you. You are probably mining Expanse instead of ETH.
You can call whatever you want. I am just reporting what I am getting, there's no beating the drum here. And I am mining ETH. Dwarfpool is reporting this hash rate. I plan to shift to another pool, I can share the hash rate then.

How long did you mine and get those results?
The numbers are never accurate, it can probably range between 20mhs-40mhs for you and average being 30
Win 10 64 Bit / GTX 970 / 0.9.41 min / mean / max: 18.343965/18.397599/18.431387 MH/s Inner mean: 12.260465 MH/s
Typical mining: 6.5 MH/s
Any ideas as to why I'm only seeing 1/3rd of my benchmark while mining?
Just in case anyone else is looking at this, rolling back to driver 347.52 fixed the issue and I'm now getting ~17.5MH/s during typical mining, without OC.

going ro build a new rig with 3-6 r7 260x's
what's the hashrate on a r7 260x?

MSI R9 380 4Go, 59°C, 45% fan : 21.4Mh/s on 24hours average, seem good
40Mh/s @dwarfpool

No overclocks and running Ubuntu 14.04, fans around ~42% hovering at 65-66 Celsius.
Getting around 58-59 mh/s total at the pool.
Not using any proxy though (is it worth setting up?)
You should just buy a $5 riser and at least hang that card somewhere where it can breath.
