Hello guys, i have this problem, when i start the miner the speed is 29.5, but after 20-30sec my speed drop about 24-25 and i can't increase ..... Please someone help me. My card is Sapphire 580 nitro+ 4gb Elpida memory
You should decrese your memory clock. had the same problem, with my 5*580 Rig. Now is stable around 13h. Try decrese memclock and you will need check HWInfo memory errors. had a lot of it.
This is happened when i copy 1500 to 2000 timings in bios! What is your speed?
This is happened only with my Asus Dual 8GB with samsung memory. When i wrote UberMix Timing - very unstable at just 2000MHz , much memory errors. Then, i copied 1750 to 2000, that more stable, but ..... Then, i decresed mem clock card by card.
-cvddc 825,825,850,825,825 -cclock 1146,1146,1146,1146,1146 -mclock 2010,2040,1930,1990,1930
1,2 - Armor with uber mix.
3,4,5 - Dual with 1750.
All of these - ETH =142MHz with DCR = 4550MHz.
