I been mining on 2 rigs for 2 months using:
windows 7 ulti.
h81 bro btc + Ram 8 GB + Intel Pentium Processor G3240
every rig have 5 cards of Sapphire nitro+ 480 8G 11260-01-20G set at 1342/2200 hashing 27.4-27.5
I saw people saying that it can be raises to 28-29 (without any mod or bios flash) only using overclock
I would like to say the rigs are stable and working good with 16.11.5 (pow lim 0 & mv -24)
The cards have samsung rams with asics (75-85) but all same hash 27.4-27.5
any help to raise would be appreciated even 0.5 for 10 cards it will be 5 Mh/s
My batch is:
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

Hello
1342 it's too high!
1200/2200 or 1150/2150.
and -48mv
With bios mod you can have 30mh
Thank you so much. Ireduced to 1266/2200 same production. noticed on 1266/2250 showing 28 Mh/s but 2250 is the max on the msi afterburner which I dont like as it is the maximum, so returned to 1266/2200. I dont like any mod it might destroy card.
If your gpu blocks the memory but not the coreclock, on these cards you can leave the coreclok at 1200.
But your gpu 4 lowers the memory to 2150.
Thank you it was a new valuable info for me after 10 months of mining. I reduced GPU4 to 2150 and the situation is too much better but I am not sure what is the accepted errors limit. here is the current situation:
GPU0 - errors: 1 - Asic:79.5 @1266/2200 -24mv
GPU1 - errors: 774 - Asic:85.6 @1180/2150 -24mv
GPU2 - errors: 1315 - Asic:73.6 @1266/2200 -24mv
GPU3 - errors: 4 - Asic:75.8 @1266/2200 -24mv
GPU4 - errors: 34 - Asic:75 @1180/2150 -24mv
GPU5 - errors: 295 - Asic:71.1 @1266/2200 -24mv
