@pbfarmer
I'm having the same issues as in the other thread we chatted a while ago.
Those Vegas are just horrible. I have to set Mem_P3 and Core_P7 at 1000 to be able to run the miner. Anything below and the miner will not even initialise and the rig reboots.
I was able to run low core voltages with x16 algos by disabling the Mem states. Got rid of all problems. As soon as I need memory (like for CN) all hell breaks loose. Here's what I'm having to deal with now:
GPU_P0=852;800
GPU_P1=991;805
GPU_P2=1084;810
GPU_P3=1138;820
GPU_P4=1150;830
GPU_P5=1202;840
GPU_P6=1250;845
GPU_P7=1408;1000
Mem_P0=167;800
Mem_P1=500;805
Mem_P2=800;810
Mem_P3=1100;1000
Fan_Min=3600
Fan_Max=4900
Fan_Target=75
Fan_Acoustic=0
Power_Temp=85
Power_Target=0
Total power draw at the wall for 6 Vegas: 1400W
You have 64s, right? Are they purchased from a (reputable) retailer, or secondhand? Starting to wonder if those things got cooked in the past and maybe you have some hardware faults now - those clocks shouldn’t need more than 850mv.
Btw - assuming these are your runtime settings... what does your ppt look like?
These are reference Sapphire 56's flashed to ref Sapphire 64.
This is my ppt:

Bought the GPUs new on Amazon back in September 2017 iirc. Chinese third party seller ofc. Could very well all be duds. Mind you they've been hashing fast and all... Just been an absolute pain on power as soon as I need memory to do its thing. As said, x16rt at 850mV core, mem pstates disabled and all was peachy.
