Temps are good. I wonder if it needs more ram or a faster cpu to handle 12GPUs.

As soon as I turn it on all are stable on 53Mh. I think I will unplug 5 cards and see what happens as soon as get to the mine.

Yes, MSI EVOKE. When I was setting up the frame I had 7 installed and achieving 56Mh at 1280Mhz Core, 910 Mem, 750mv on the core. Now I installed all 12 and with these settings I am getting 53.5Mh. I get the same results on Windows and HIVE OS

One more question, after I added all the GPUs I cant reach the 56Mh from before. Does it have anything to do with the RAM or CPU? Any ideas? Running on 4GB ram and G3930 CPU

Thank you gentlemen. My observations is that under 740mv core clocks start dropping under 1200mhz and hashrate suffers quickly. 56.3Mh requires 1280Mhz Core or more.

So far so good, I modded the timings and I am getting 56Mh on all cards. I am using the morepowertool to undervolt the core to 750mv. GB Fintech B250 MB with G3930 and 4GB RAM HP Server PSU 1200W 94% Phoenix 4.9C on Windows Problem is a am getting about 140W from the wall per card. I see people doing under 100W. What I am missing? Thank you! Set core state to 2 and core clocks between 1180-1300. Then VDDC 750-900 range Its set to state 2 and vddc is 750mv. Anyway I guess thats the best my cards can do. Btw I googled minerstat because of your post. Awesome stuff, trying it out now on 1 rig.

Quote from: deadsix on February 17, 2020, 04:24:40 AM Quote from: Penchev on February 16, 2020, 07:55:19 AM Guys, I need help with my 8xVega 56 Sapphire Pulse. Samsung memory. If I try to go any higher on the memory some cards start dropping to 7Mh like this: https://ibb.co/Qn2WfBs I know people clock to 1100 and get 50Mh. Help please! Cards drop hashrate when the memory is overclocked too much, since it starts producing too many errors and the computations have to run and rerun, resulting in a lower hashrate. Just because you have Samsung memory does not mean it WILL clock to 1000+. Its a trial and error thing for each card, some will work, some wont. Its called the silicon lottery, dont push your hardware to breaking point. Also when overclocking, test 25mhz increases and go up stepwise, not directly from 950 to 1025. Thank you for the info. Yes, I do try at smaller increments! For me it doesnt make sense to have such a big difference between cards with Samsung memory. So I was asking if I am missing something, maybe I have to tweak DPM and MDPM levels in HIVE OS? Thanks anyway

Guys, I need help with my 8xVega 56 Sapphire Pulse. Samsung memory. I flashed it to 64 Bios hoping it will allow the memory to go higher. I am using this for mem tweak and it works well. I get 44Mh at 950mhz amdmemtweak --CL 19 --RAS 30 --RCDRD 12 --RCDWR 6 --RC 44 --RP 13 --RRDS 5 --RRDL 5 --RTP 4 --FAW 18 --CWL 6 --WTRS 4 --WTRL 9 --WR 15 --WRRD 1 --RDWR 18 --REF 17000 --RFC 248 If I try to go any higher on the memory some cards start dropping to 7Mh like this: https://ibb.co/Qn2WfBs I know people clock to 1100 and get 50Mh. Help please!
