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. I think this is very low hashrate for these cards, wtih 1750 my speed is 26.4.... I don't think so. 28.1 , 28,75 , 28.2 , 29.2, 28.25 - ETH 895,920,900,930,900 - DCR if i try to get higher mem clock - lot of errors, hashrate slowdown , very unstable rig . Maby i can do 1,2 cards get higher over 145-146MHz, but i don't want right now, i need time to relax ))) And another one, i had only one psu RM850X Corsair and i don't want to increse vddc . Thank you man, i mod bios with 1500 and i decrease the memory clock to 2030 and my speed is 29.3 now  |
