I'm not sure if this is exactly what you're looking for? I don't know about RUN, CLONE, or GEN?
The primary monitor is on display-port.
Plenty of monitor blank-outs and here was the latest from the log:

Code: Select all
11:54:08:WU02:FS02:0x22:Completed 800000 out of 1250000 steps (64%)
11:55:29:WU02:FS02:0x22:Completed 812500 out of 1250000 steps (65%)
11:55:31:WU02:FS02:0x22:Checkpoint completed at step 812500
11:55:31:WU00:FS00:0xa7:Completed 140000 out of 500000 steps (28%)
11:56:52:WU02:FS02:0x22:Completed 825000 out of 1250000 steps (66%)
11:58:15:WU02:FS02:0x22:Completed 837500 out of 1250000 steps (67%)
11:59:01:WU00:FS00:0xa7:Completed 145000 out of 500000 steps (29%)
11:59:34:WU01:FS01:0x22:Completed 1760000 out of 2000000 steps (88%)
11:59:37:WU02:FS02:0x22:Completed 850000 out of 1250000 steps (68%)

I am not actually seeing these blank-outs in connection with TDR events.

Each "WU" (Work Unit) is part of
a project (PROJ), that is, a protein under study,
a run, that is, a particular simulation of that protein started from a specific situation (conformation),
a clone, that is, such a simulation at a specific initial velocity,
and a generation (GEN), that is a piece of that clone.

A WU is thus designated by four numbers called the PRCG numbers : Project (Run, Clone, Generation), eg. 16918 (139, 146, 0).

All the information John Chodera was talking about are in your log: viewtopic.php?p=327412&f=24#p327412

Thanks,

A reaction to overheating is not ruled out. I had been out of the f@h game for a while and was rusty on the tools such as MSI Afterburner to program the GPU fan curve. I am using higher GPU fan speeds and it is keeping the GPU about 15 C cooler.

Probably helpful :?

If you've been out for a while, there's a reasonable chance that your hardware has accumulated more dust than it needs in the cooling passages. (Zero is good :lol: ) Consider a careful internal cleaning of passages where air is supposed to cool things down.

Yah, it was just the software tools to monitor the the GPU etc. that I wasn't using for a while. I'm not even sure if I ever F@H on this 2070 so I'm not all that familiar with its behavior.
I still have no idea what for certain is causing the monitor blank-outs. The innards of my tower are sparkly clean. The NZXT H700i seems to have quite good positive/negative pressure plus quite fine dust screens. I also use a DataVac on it once in a while.

Looking forward to future details even if I only provoked research and refactoring than that's great too. :roll:

Windows has a intermittent black screen issue so it may not actually be a FaH issue as such just that FaH triggers/exacerbates a windows issue
1: 2x Xeon E5-2697v3@2.60GHz, 512GB DDR4 LRDIMM, SSD Raid, Win10 Ent, Quadro K420 1GB, FAH 7.6.21
2: Xeon E3-1505Mv5@2.80GHz, 32GB DDR4, NVME, Win10 Pro, Quadro M1000M 2GB, FAH 7.6.21
3: i7-960@3.20GHz, 12GB DDR3, SSD, Win10 Pro, GTX 750Ti 2GB, FAH 7.6.21
