I sent the monitor in for RMA. There was no dead pixel, but rather dirt in the panel. They changed my panel instead of giving me a new monitor, which I'm kind of salty about, but we'll see, I don't have it in my hands yet. Bad thing is, the service guy told me that he could not reproduce the problem with the DP connection, so they said I should either try with another GPU or contact the manufacturer of my GPU. So I sent an email to MSI support and I'm waiting for the "screw you" response I'm expecting. The way this whole thing looks, I'll probably have to buy another GPU if I'm to enjoy this damn thing, provided it doesn't give me even more problems. Worst thing is that I don't wanna go NVidia and, apart from the rather expensive Radeon VII, there's nothing REALLY better than the 390x on the AMD side. I mean, +5-10% at best isn't reason enough for me to go 580 or 590. I was really hoping for Navi, but I doubt I'm gonna be able to wait 'til the summer for it. Unless money (or lack thereof) forces me to wait and not buy a VII. Sigh...

PS : Got a response from MSI. First message gave me some general crap about reinstalling drivers and cleaning ports on the card. After I explained that I've tried everything, the guy sent me a shady looking BIOS flashing folder, complete with ATIWinflash and some other stuff that I don't know anything about. I'd appreciate if anyone gave a look.
Hi, do you have tested to not use freesync, maybe your monitor going to black problem is caused by it. About the BIOS flashing folder the bios is the TV308MH.201 file.

In 380, and polaris gpus, the wattman memory voltage is not the memory voltage and is the voltage floor for the core for per dpm memory clock. Maybe in the 390 is the same. In vega @gupsterg have tested that it is the dpm5 voltage.

About the memory voltage (mvddc), I think I know a way to know what voltage is using you gpu for it. I see info about it in two bios tables, ASIC_Init and VoltageObjectInfo tables. The ones I see into the TV308MH.201 bios file are:

ASIC_Init:
91 00 01 01 00 08 02 01 02 00 52 47 52 02 02 65 02 07 52 0D 55 00 02 52 0D 52 23 2C 25 02 01 3D 25 02 06 45 17 00 51 02 4A 25 6F 22 06 49 3E 00 01 05 00 C2 00 00 00 E0 5C 25 70 22 F9 04 52 39 02 0D 02 01 03 52 43 66 04 02 8C 02 2E 00 02 0D 02 01 00 52 43 02 05 02 04 00 E8 03 52 43 02 0D 02 06 03 52 43 02 0D 02 02 03 52 43 52 05 02 01 02 00 0E E5 02 08 52 0A 02 05 02 02 00 DC 05 52 43 02 01 02 01 0E E5 02 08 52 0B 0D 65 D0 05 02 5B

VoltageObjectInfo:
70 00 03 01 01 03 0E 00 08 96 60 00 00 00 00 00 FF 00 01 07 0C 00 0A 00 00 00 00 00 00 00 04 07 0C 00 0E 00 00 00 00 00 00 00 02 00 24 00 00 04 00 00 00 80 10 00 00 00 00 00 1E 05 00 80 00 00 46 05 00 00 10 00 DC 05 00 80 10 00 0E 06 06 03 22 00 0C 96 A6 00 00 00 00 00 D4 00 F0 00 D5 00 F0 00 D6 00 F0 00 D7 00 F0 00 D3 00 40 00 FF 00

In the first table DC 05 is 1500 so is 1.5v, so your gpu could be using 1.5v. I saw 390x bioses with 1.55v to this value so maybe that is why you are getting errors and other people not.

In the second table there are other voltage values related to the memory voltage. 1E 05 1.31v, 4605 1.35v, DC05 1.5v and 0E 06 1.55v. I think these voltages are the ones the memory can have. I think no other voltage can by aplied.

So I think that if you change the first table DC 05 (1.5v) value to 0E 06 (1.55v) you could have 1.55v for the memory.

As mvddc can't be monitored by any software there is no way to know if it is working without a multimeter, or testing and see if you get less erros. Anybody have tested this, so if you whant to do this do it in your own risk.
