Use this before your command line if your cards are with 2 or 3 gb:
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
ethminer.exe --farm-recheck 200 -S xxxxxxx:xxxx -O x.x.xx.x.x.x -G --cl-local-work 256 --cl-global-work 16384
Topic: Suddenly can't mine Daggerhashimoto/Etherium on nice (Read 654 times)
IMO I think it's pool side not your miner
Try a different pool and see what happens
I couldn't get claymores xmr or any other xmr miner to mine at nicehash all I got was rejected shares

These are all 3GB cards, have we reached that epoch already?
Actually no, but then you have an interesting problem here

time to swap your cards 
suddenly you should read about the size of dag file and old cards
I have 3 systems with various 7950/280 Radeons mining Etherium on nicehash fine for a year and all of a sudden all 3 rigs can no longer mine it. They all get 0hash rate. I can mine other coins, right now i'm resorting to neoscript, but i get under 1/3rd of what daggerhashimoto gave. Anyone know what could be wrong? I've tried the lastest 1.7.3.11 nicehash miner, catalyst 15.7 and redownloaded the miners and reconfigured but they still won't mine.
