despite the random card dropping, OC seems to be very straight forward.... getting 302.5H/s per 7950.....

Claymore, why I 7850 1GB card speed of only 120 H/S, and 7850 of my 2GB card to 220H/S, the same configuration

Miner requires a lot of GPU RAM. For full speed 3GB is required for 290/290X/280X and 2GB for 270/270X. If miner cannot find 2 GB it will work with 1 GB but much slower. Note that if something is wrong with memory allocation miner won't work a bit slower, it will work much slower (in 1.5 - 2 times), so if someone has 400h/s instead of 450h/s - memory allocation is not the reason. |

5*280x only 1227h/s - why?
Win7
12Gb RAM
driver 13.12
Set Virtual Memory 16 GB.
no under voltage

Are you sure you use 13.12? When I install 13.12 after 14.4 Catalyst still shows "14.x" version, so I have to start AMD Clean-up utility firstly to remove 14.x, and then install 13.12. |

The problem is not in memory, the problem is in OpenCL stability when almost all available GPU RAM is used. I cannot reproduce this problem on my rigs for some reason, so it will take some time to find a workaround (if possible). |

I realized what the problem is. Crash one of the cards at the frequency 1100 MHz. Is it possible to set the frequency is less than the miner for the core graphics? |

mining other coins cause this miner is not stable at all, driver crash and drop 1 of my 6 GPU activity, i tried everything and nothing seems to be working. I can mine without problem XPM, X11, X13 and scrypt without problem

 Tried it on my old laptop. Pity that it is stuck on outdated Samsung AMD 12 drivers. Anyways it sort of worked with a few accepted shares every now and again, miner doesn't give a hash rate though. Its a 7670m btw. (and yes I've set more than 16gb of virtual memory). After a while it stops working though. Support for other driver version would be nice. |

Hm... protected with VMProtect. Not bad.
What are you looking for in binary? |

What are you looking for in binary? I've nothing better to do, really. Why? I saw your improvements, they are great, I see the miner can be optimized even more. |
