I have the same problem on 4 rigs with 4 various Vega 56 cards (ref with samsun g and asus/powercolor with hynix, with timings and without timings ). The card runs for an hour or two and then the hash rate drops to zero or to 1400 h/s with a DEAD message. I have observed in several rigs, but for some reason problems always with the first PCI slot (PCIe 3:0.0). If you do not stick the card into the first PCI slot (PCI 16x), then the problem disappears. Now I just do not use 16x pci slot Sad

Hi, interesting... for me it is GPU4 and it is located at PCIex16 slot too.

All primary x16 slots on any motherboard always are uplink.
What hardware do you guys have? (only for the vega rigs)
H110 3da with latest bios (F25), Celeron G3900 (Skylake) all (2) cores enabled. igfx enabled as primary. and a vega 56 in every pcie slot (stock bios, but we've already established bios, settings and algo don't matter). Single channel & single bank 4Gb memstick Crucial.

For most of us TRM 4.4 seems to work normally although a teeny tiny bit slower, but it's still better than a whole card not running

. 5.2 only just released, so can't say yet.
