MSI RX 580 Armor 8g OC (Micron vs Samsung) - issues with Samsung

[yoyome]

Just got done setting up my 2nd rig with 3x MSI Rx 580 Armor 8g OC.

Mobo: Biostar TB250 Pro Btc
Cpu: Celeron g3930
Ram: 4gb
Amd driver: Adrenalin 17.12.1 (compute workload)
Claymore v 10.6
OverdriveNTool v 0.2.4
SRBPolaris v3.3

1st card out of the box had Micron mem as reported by GPU-z.
Stock hash 27.xx Mh/s eth+sia

Opened the bios in srb and noticed 3 sets:
K4G80325FB (Samsung)
H5GC8H24MJR (SK Hynix)
MT51J256M32 (Micron)

copied 1750 straps to 1875 and 2000 just for Micron > saved > flashed > rebooted

did not need to patch the drivers with the pixel patcher... everything looked ok.
set cclock 1180mhz mclock to 2150 mhz and power to 850mV in odtool..

New hashrate: 31.xxx mhs eth + sia rock solid no mem errors in hwinfo.

2nd and 3rd cards both have Samsung memory as reported by gpuz

stock hash 26.xx eth+sia

in srb 2 sets:
K4G80325FB (Samsung)
H5GC8H24MJR (SK Hynix)

copied 1750 to 2000 only for Samsung

no need for pixel patcher driver worked fine after reboot
set cclock 1180mhz mclock to 2150 mhz and power to 850mV in odtool..

new hashrate 1 card 28.xx the other 29.xx a lot of mem errors for both.

tried uber-mix 3.1 strap:
777000000000000022CC1C00AD615C41C0590E152ECC8608006007000B031420FA8900A00300000 010122F3FBA354019

played with cclock and memclock and voltages, got both stable @ 29.xx mhs with 1180 cc 2020 mc 900mV

is Samsung not capable at running @ 2150 mclock??? I got shit tons of errors at that speed and even a bsod

keep in mind, I'm still a complete n00b at this, so bear with me...
any help is greatly appreciated. will tip (eth) for a 30+ mh/s on these samsungs

Try these timings - this is a modified Uber
My RX480 with Samsung memory does not work with frequencies above 2100Mhz, I get a lot of errors.

thx @fapar

I appreciate the effort...
tried your strap, got both samsungs to 29.xx but with hdw errs in the hundreds within 1min
clocked at 1150 cclock 2050 mclock 950 mV

it is actually on the high end of 29.8xx but would like to get rid of those hdw errs completely.

any suggestions?
