Mining Rig Help Needed - Windows Login Freeze

[Spurs]

Morning All.

I built a rig a few months back and it's been mining well once I got through all the standard issues a first time builder runs into. Just recently however after switching to the claymore miner and mining through nanopool, my rig began to experience some issues. It would mine for about ten hours and then I started getting BSOD. After about three of these, windows started to crash at startup. It would get to the windows loading screen, the dots would circle twice and then stop at the same point and restart.

I carried out a complete reinstall of windows after clearing CMOS settings with only one of my 8 GPUs connected and windows is now operational again. I've downloaded the latest GPU driver through GeForce Experience, made sure all the drivers are up to date and got the latest windows update and everything seems stable with one card connected.

The wall I've run into now is that when I try to reconnect any more GPUs and start the rig, I'm hitting the issue with the windows loading screen again. As soon as it gets to the loading screen, the rings circle once and then everything freezes at the loading screen? I've tried with just the 4 GPUs I have connected to the same power supply as the MOBO, CPU, hard drive etc. and I've also tried with all 8 connected (4 GPUs on the second power supply) and still run into the same loading screen freeze point.

Rig Specs:
ASRock H110 Pro BTC+ 13GPU Mining Motherboard
Intel BX80662G4400 Pentium Processor G4400 3.3 GHz FCLGA1151
2 off EVGA SuperNOVA 1600 T2 80+ TITANIUM, 1600W ECO Mode Fully Modular
Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)
8 off Gigabyte AORUS GeForce GTX 1080 Ti Xtreme Edition 11GB Graphic Cards GV-N108TAORUS X-11GD
VICTONY PCI-E 16x to 1x GPU Riser Adapter 60cm USB 3.0 Riser Flexible Extension Cable & MOLEX to SATA Power Cable

I have kept all risers connected to the same PSU as the cards and have the first four GPUS on the primary PSU and the other four GPUS on the slave PSU.


Any help here would be greatly appreciated! It's been hard going from a perfectly functioning rig to this hahaha!

how are your risers connected? never use sata
i had the same on one of my rigs after months of running stable, connected all risers with molex or 6pin -> problem solved

edit: btw if you add more gpus the ring freeze on windows bootup is normal, because windows installing drivers. but it shouldnt last more than few minutes

Okay so I should maybe try leaving it at the frozen windows loading screen for 10 minutes or so?

As for the powered risers I've got it connected via the molex to sata cables that came with the risers (molex on the riser, sata connected to sata power cable). Will need to check if the PSUs came with enough molex power cables this afternoon.

"molex to sata" i knew it ...yeah leave it for 10-15 Minutes, if its still frozen then its something else...if i install new drivers on my rig, few minutes after the ring freeze the fans of my gpus start and stop spinning and a little bit later the installation is complete


and you should change the riser connection anyway...otherwise it will cause more problems sooner or later

Appreciate the help! Will trial it tonight and see if these changes help the situation at all.
