Ok,I have a Visiontek 7970 mining with "ethereum-mining-windows",it works just fine.Just got a Powercolor 7970 & using the same miner it keeps getting "Allocating/mapping single buffer failed with: clEnqueueWriteBuffer(-4). GPU can' t allocate the DAG in a single chunk. Bailing."
I've tried 13.2 (same driver I use for the Visiontek 7970),14.9 still gets the same response after DL'ing the DAG.
@bithexall your hashrate is ridiculous. I confirm that a 295X2 can mine at stable 50mhs, even 55mhs if you overclock it. Try ethpool.org with qtminer (available in the FAQ section). That's what I am using and it rocks :-)

Any ideas???
How much memory does your GPU have? If less than 2 GB it will crash. I use TechPowerUp GPU-Z to view graphics card specs and temps, etc.
@Marvell9 thx i already registered with Cointron, but I did not use yet the multipool coin is a concept there is not clear to me, I also would like to know why you asked MrYukonC not to refer me to Dwarf pool ? @MrYukonC my hash rate as reported by eth.ppa.us is 40Mh/s which unlike nanopool that seems to have less revenue last three days, now do I need geth synched before using Cointron? thanks all , I still have question up there that someone may want to answer

3GB,It is a Powercolor 7970,I'll post the full results in a bit......Oh,does it matter if the PC has a dual core CPU???

@Unacceptable are you using GPU_MAX_ALLOC_PERCENT=100 and GPU_SINGLE_ALLOC_PERCENT=100 env vars?
Uh no,I'm using a bat file on Win7 "ethereum-mining-windows".
As I said I have Visiontek 7970 running on another PC just fine with the same bat file,for some reason this card will not mine,I even swapped it out on the Visiontek PC & same results,very wierd.

I'm very impressed by these so far, seem to be faster than most people report for 380's

yes they are , XFX seems to have the best cards out there
@Biodom I'll double check one of the cards I have a 390x and 390 XFX black i'll run them solo against the pool and see what the current numbers are and repost here.
Remeber though i dont OC or underclock XFX cards are supposedly best for undervolting and overclocking since they have quality Samsung memory, so I'm probably not getting the most of of them.
Im getting with pool 0,35 ETH per day is this normal? Honestly I payed 13 MH/s with genesis mining and Im getting around 0,27-0,29 ETH per day.. What do you think where is the problem, I cant figure it out....
I have question 2 days ago I was with 1 rig 4x 280x and in my own pc 1x 390 and I was getting around 130mhs and now the 280x and the 390 are in 1 rig but I am getting something like 90-95? What is wrong? I install only the driver for the 280x is there the problem? Did I need to instal the 390 too?
Im getting with pool 0,35 ETH per day is this normal? Honestly I payed 13 MH/s with genesis mining and Im getting around 0,27-0,29 ETH per day.. What do you think where is the problem, I cant figure it out....
0.35 per day per 280x is normal.
25MH/s is not the real hashrate, realhashrate is like 20MHS for 280x

Thanks, for reply but if 20 MHS is the normal online calculators says that 0.430092 ETH will be the normal income is it right? 0,33-0,35 is not too low?

Thanks, no different from others.
I wonder why their 380 is apparently better than some others, but 390ies are not?
