POWERCOLOR RX 580 8GB Problems. Wattman settings?

[CrayjeksAjek]

Howdy all!
Currently I have a problem with the rx 580 8gb card in ethereum/sia mining. My rig will run for 8 hours at a time before crashing/restarting my PC. Here are some specs:

Win7 x64
MSI 970A‑G43
AMD Athlon II x4 630 @2.80GHz
32GB DDR3 RAM
2TB SATA HDD

Crimson ReLive 17.6.2 drivers
XFX Hard Swap Radeon RX 480 8gb
XFX AMD Radeon RX 480 8gb
VisionTek OC Edition RX 480 8gb
Powercolor RX 580 8gb

I have all cards set, in Wattman, to
GPU @ -16.5% Intensity
State 6 @ 910mv
State 7 @ 929mv

Memory @ 2200mhz
State 2 @920mv for the RX 480's
State 3 @930mv for the RX 580

Im getting 27mh/s across the board but after 8 hours of mining my PC restarts. Ive been running the 480's fine for months so I know its the 580 crashing. Ive tried some tweeking but every 8 hours my PC will still crash.

Does anyone have Wattman settings for the rx 580 8gb? Im trying to find that sweet spot but its a pain having to wait 8 hours every time to see if it crashes.
Newest 580 settings are at stock mV for core clock @ -16.5% intensity with auto/stock mV @ 2150 for memory. Its been 2 hours........

Think I finally have a good setup with the rx 580 8gb without modding the bios.

In Wattman im at -16.5% intensity with states 6 and 7 mv at 910 and 929
Memory clock at 2200mhz with a mV at 875.
Been hashing at 27mhs for almost 12 hours now.

Samsung Memory

Nevermind. Crashed just after 12 hours.
Volted memory to 879 now. Lets wait again

HI!
Please tell us how you managed to achieve good performance without changing the BIOS? Only with Wattman?
Which driver are you using now?
