What about when you run every state @ 900? What does hwinfo say about SOC in that case? Or are you sayin opening hwinfo while mining causes a crash? If so, try running hwinfo first
When I run every state @900 it's working (for almost all card execpte bad ones 4/22) and hwinfo is reporting 895mV, 1107 SOC
Ok - one other possibility... somewhere between the TRM implementation, and newer versions of drivers, I feel like Ive seen instances of transitional states lighting up long enough for voltage settings to actually matter. Its possible youre crashing during the p4-p5 transition going from 800 to 1107, as 820mv may be too low (or something like that.)
Try setting either a more graduated voltage list, or set every state to your final voltage (I would suggest the former, in keeping w/ the PPT as floor concept.)
Ok I will try this ,
I just reinstall 18.6.1 on my test RIG ( 1 Vega 64 and 4 vega 56/64bios) (Most of them are bad card).
I Used 850mV PPT from page 67:
Name=VEGA 64
GPU_P0=852;800;0
GPU_P1=991;810;0
GPU_P2=1084;820;0
GPU_P3=1138;830;0
GPU_P4=1150;840;0
GPU_P5=1202;850;0
GPU_P6=1212;850;0
GPU_P7=1408;850
Mem_P0=167;800;0
Mem_P1=500;800;0
Mem_P2=800;820;0
Mem_P3=1100;850
Fan_Min=400
Fan_Max=3200
Fan_Target=65
Fan_Acoustic=2400
Power_Temp=80
Power_Target=0
and for memory timing I use :
VEga 56/64bios : --i 2,3,4,5 --CL 20 --RP 11 --RC 44 --RCDRD 12 --RCDWR 8 --RFC 250 --FAW 20 --RRDS 4 --RRDL 4 --RAS 32 --REF 7800
Vega 64 --i 1 --RAS 32 --RCDRD 12 --RCDWR 5 --RC 44 --RP 12 --REF 15600
I will try to stabilize the rig ( most of them cannot handle 1100 mem) and let you know.
Thanks for helping me ( I'm trying my best ) (and sorry for my english)
