Im using sapphire nitro plus vega 56 with hynix memory. I get few HW errors per day
using this
amdmemtweak --CL 20 --RC 36 --RP 13 --WR 13 --CWL 7 --FAW 12 --RAS 23 --REF 65535 --RFC 248 --RTP 6 --RRDL 5 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 18 --RCDWR 11
960 memory at 812 voltage core 1075.
Should i be worried about those HW? getting around 49mhs.
at rcdrd 20 i got 1 HW after 12hrs. or maybye someone has straps or oc that would work better?

Try the same settings with mem 940. If I go above 940 with my Hynix this doesn’t change hashrate. BTW a few invalids per day if nothing

hey. how is frontier edition vega performing, thats 16gb, right ??
hey, have u managed to tune those ?
U could try to gpu 0 &1 mem 1020 / vdd 820 / core 1130
straps
amdmemtweak --RC 37 --RP 12 --WR 13 --CWL 8 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 6 --RRDL 5 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12
For gpu 2, the hynix one,
try mem 940 / vdd 820 / core 1050
straps
amdmemtweak --CL 20 --RC 36 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 12
Hope these works for you, good luck
Yes sir, ive got it mining at 41.
My 2 Hynix cards can’t start with SoC set to any of 960, 1028, 1107. I have mem set to 940.
Hello guys!
Im new to mining and I’m not sure if this is the right thread to ask for help. If not, please point me to right direction.
Equipment:
MB: h110-d3a
Corsair RM1000X
Vega 56 x 3
RX480 x 2
My problem is mixing Vega 56’s with my RX480’s. Everytime i try to mix them, the Vegas wont mine at all. They are detected but only the RX480’s will mine. And when i remove the RX480’s, the Vega 56 will begin to mine(then the rig only includes Vega 56 x 3). I have tried changing risers, different powering to riser(molex and 6pin, no SATA), just 1 x Vega and 1 x RX480(if power consumption problem) but nothing works. Also different PCIe Gens(auto, 2 and 3) from MB Bios settings.
I have also tried different miners(Bminer, TRM, phoenixminer). Same problem also occured in RaveOS. And also adding GTX 1070 to the rig stopped the Vegas from mining.
If you have any tips I will gladly try out them.
Sorry for the late reply, I was not behind my computer for a few days. I should have mentioned I was fiddling around with some Samsungs.
And now that I’m digging deeper in it, it seemed that I had even set some wrong straps on those Samsungs; that’s why I couldn’t get their mem clock higher 
yet their SOC could be set higher manually.
Now that I have set the proper straps, I got their mem >1000, so their SOC are automatically set to 1028.
Sorry for all the confusion 
I need more sleep…
i wa sreading that it can do over 70.so not true likely. must be good gpu, wouldnt mind to have one to play with 
if u try to remove that mvdd u could get a bit more hash with stil keeping rig stable. So it didnt like´d core 1050?
its wery good allready. congrats . good luck with mining…to us all !
I have no idea how to optimize my GPU’s, i just select default config. I am also mining inside a VM with GPU pass through. I have not played with it at all, so take my benchmark as the bare minimum… lol

That output is great for Gigabyte. I’m struggling to get my Gigabyte Vega 56 OC to reach more than 46MHs.
What is the memory straps parameters that you apply?
This one for example:
amdmemtweak --CL 19 --RC 36 --RP 12 --WR 13 --CWL 6 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 4 --RRDL 5 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 15 --RCDWR 4
With core 1080, vdd 830, mem 940 it gets around 51MH/s
I guess @steroid his RCDRD is lower? But I can’t get mine stable with lower than 15.

so called “default” straps are not so bad actually, maybe change few values, like ref to 65535 and rc to 36 if your card can handle it, allso RCDRD to 12 on samsung and 14-- in hynix and u should get decent stable hash.
Thank Oni, I’ll give it a try later on
I was running these straps with Hynix Gigabyte with about 52mh
amdmemtweak --CL 18 --RC 34 --RP 12 --WR 13 --CWL 6 --FAW 12 --RAS 22 --REF 65353 --RFC 164 --RTP 4 --RRDL 5 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 12 --RCDWR 4
Mem mh was 935
Didn’t have invalids with these settings but it depends on every single card

Thanks steroid! Will give it a try
