i been mining ethereum for a couple weeks.. no issues.. just using the standard -G -F and the url..
i switched to the NH software a few days ago.. it uses some proxy thing, but it was working..
today a few hours ago my mining stopped.. it says..
Allocating/mapping single buffer failed with: clCreateBuffer(-61) GPU cant allocate DAG in a single chunk, Bailing.
i thought it might be the NH software so i tried to go back to regular ethminer.. but nope same error..
nothing has changed on the pc.. its running windows 10..
i had the catalyst 15.11 drivers installed.. but i tried going to the new 16.3 hotfix drivers and same thing..
my gpus are 2 r9 270X. i was getting around 34Mh/s with them.

Use those before the ethminer
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

I couldn't even start mining it. Got the exact same error. Tried everything I could find. Started mining another coin to trade for eth.

can you explain what they do? especially those first two, i know about the other, but never heard about those, can i still play games for example after setting this, without problem i mean |

ok 100% sure its not the computer..
i just tried my other computer.. this computer has 2 7970 gpus..
same error.. even tho i dont mine with that computer (it gets HOT) i have before and it ran just fine..
so something in the DAG changed today.. something my gpus dont like.

try adding --cl-extragpu-mem 0 to your command line. at some point it may require running the cards headless (no display).
my fork has this defaulted to 0 since 1.0.6

where do i download 1.0.6 for windows? i am using 1.0.3 edit that worked.. back in business.. thanks ok so 0 isnt going to work, crash video driver.. i checked out what that does and it reserves gpu memory for windows? i am trying 16.. think i read it defaults 64? its MB? its been running a few minutes at 16, no crashes yet. |

Same issue here. Got my 7870 running again with a bat file containing this: setx GPU_SINGLE_ALLOC_PERCENT 100 set GPU_SINGLE_ALLOC_PERCENT = 100 ethminer -G -F http://poolstuff.com --cl-extragpu-mem 0 /offtopic. *me waves at genoil* (Hashrate is down from 15/16 to 10.5ish :S ) |

No those are only for sha256 algorithm coins like bitcoin. |

Not sure if anything can be done about it. |

Try this on the original ethminer without the extra mem flag
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 95
setx GPU_SINGLE_ALLOC_PERCENT 95
And for the local work use 16384 for slighly higher hashrate
I tried the --cl-global-work 16384 --cl-local-work 64 and it gives higher result. But changing the 64 to 128 has no effect. Anybody notice that? |
