hey guys, and then especially mean eliovp and wlof0
i have 6 sapphire rx 480 nitro+ 8gb cards, a 128gb ssd hard disk, a brand new corsair 1200w platinum power supply , Powered gpu risers and an old 4 pci slot motherboard. i run windows 10 ( not a bought version , i ativated it with an activator and disabled windows update ... ).
one of these days my h81 pro btc motherboard should arrive that i ordered.
The situation is the following , for 2 weeks now i am trying to get my rig ( 4 cards at the moment ) stable but its not working... i started of with claymore miner and with standard roms and no
over or undervolting and memory tweaking it runs stable... but i dont want 640 hash at a high power consumption.
so i started just by copying the 1750 straps to 2000 straps and i flashed all cards with the new bios , after a few hours my rig crashed ( windows crashed because off an amd driver crash accroding to "who crashed" ). and this still just by copying the 1750 straps to 2000... if i start undervolting or higher the mem from 2000 to 2150 then i get great results ( still with 1750 timings ) but it is absolutly NOT stable.
after all that misery with claymore miner i tried sgminer , it is a bit slower but it looks like it is more stable, anyway when i try it with 1750 straps again , the miner seems to block after several hours ( just the mining software , windows is not crashing this time ). so i wrote a script to restart the pc every 2 hours and that worked, but still not happy because i hear all kinds of story of peopel with great results and great power consumtion and that runs rock stable. So i tried and tried and tried , last bios i tried was V4 bios from " jukebox " , that looked promissing but still crashes on claymore miner and blocks in sgminer.
After all that trying i have problems with sgminer and claymore , my fans go nuts after an hour on sgminer and in claymore i just cant control the fanspeed or temperature target anymore. in claymore the fans always run 27 - 28 procent and temperature runs up to 85+ degrees...
So i stopped my miner , and i await my new motherboard ( asrock h81 pro btc ) , i will do a clean install of windows 10 ( still with activator ) and hope that with the new mobo it will run more stable. i will start again with just copying 1750 straps to 2000 and see... and i want to start with only 1 card... hopefully i can control fan speed and temperature again.
guys ( eliovp and wolf0 ) could you please tell me what to do , can you tell me that just copying 1750 timings to 2000 is not enough to run rock stable? if thats the case i will consider buying the rom ( i dont want the super 850 hashrate but 750 rock stable and low power consumption would be perfect for me ). so please respond or PM me , i am kinda desperate right now , i invested some money in something that does not really run at this moment. and i planning to buy more rx 480 if i get it right with ( hopefully ) your help.
thank you so much in advance
Was the rig stable prior to flashing? Rigs should be stable at stock bios otherwise there is a rig issue that needs to be resolved. Some cards don't take a flash as well as others.
