Another long overdue update on this one. After upgrading to windows 10 somewhere around october 2016, the system sporadically suffered from black screen lock ups, which were TDR errors. Cue a lot of faffing and fiddling, involving a full strip down and me swapping my GTX 780 out for a spare HD6850 and no longer having problems. I tried the 780 in a spare AMD 990FX system and it was all good there too. Getting pretty annoyed by that point as I'd flashed the default bios on to the gpu, removed all my overclocks, changed drivers and applied more updates than I could remember and finally had to rebuild the watercooling to remove the GPU.
Took the opportunity to change coolants too.
After a month of no problems with the 6850, I put the 780 back in and back to square one. Eventually after 6 months of putting up with this, I managed to stumble across something on the nvidia forums regarding intel VT-d being a potential cause. Shut it off and finally got a reliable system once again. Doesn't help that asus didn't keep VT-x and VT-d in the same menu in the bios and they called it something totally different. I put the 780 back under water and restored the skyn3t bios and both the cpu and gpu overclocks and it has been great.
How it looks today. Took the HDAV surround daughter board out as I'll admit that I have never actually used it, instead opting for DD live via bitstream through toslink if I want surround. I added an AJA kona capture card which I've been using to transfer my old VHS tapes to file. Lastly a 4TB WD Se disk was added as I was running out of space for my photos.
Other changes include a ducky shine 5 keyboard along with a smaller ducky desk mat. Swapped the iiyama 4:3 panel out for another 16:10 24" panel. (HP LP2475W AH-IPS) Not a perfect colour match to the dell VA but not far out, certainly no worse than the iiyama. It has substantially less input lag than the dell so it's become the primary display. I'm planning on replacing the desktop with some nicely oiled full stave ash which is a tad longer so the monitors fit on properly and the JBL control ones behind the monitors have more room to breathe.
Only problem now is that I'm super tempted to replace it all for an X399 & 1920X threadripper system. It's one heck of a cost though. The annoyance would be having to replace the sound card which is an original xonar essence ST which uses PCI not PCI-e. Thankfully the AJA kona capture card is PCI-e as that would be very expensive to replace.
Potential spec is looking like:
AMD ryzen 1920X
Asus Prime X399-A
EK supremacy evo TR4 acetal
32GB 8 pack dark pro 3200 ram (4x8gb)
Bit's I'd stick with for now:
GTX780 3GB (will replace in next gen)
Corsair TX650 psu (hopefully still sufficient)
Crucial M500 240GB + 4 other random disks + Bluray writer (nvme ssd to come in future)
