Already been messing around with this rig for a couple of days trying to troubleshoot the problem but now I really dont know what to do.
* OS - Win 10 Pro 64 Bit
* MB - MSI Z270 SLI Plus
* CPU - Intel Pentium G4400
* RAM - 4 GB hyperx ddr4 2133 hz
* SSD - Kingstong 120GB
* 4 x GIGABYTE GeForce GTX 1070 WF - 8GB
* 2 x GIGABYTE GeForce GTX 1080 Ti Gaming OC - 11GB
* 2 x Corsair RM1000i (each PSU powers 1 TI, 2 1070, 3 risers)
* Risers - mix of brands, powered by 6pin and molex
Have been trying to mine with CCMiner - 3 different versions, multipoolminer, nicehash and awesome miner. No matter what software I use, my rig end up freezing within the first hour. No errors to be seen. Only way is to forceshutdown the rig. Were able to benchmark with both nicehash and multipoolminer, but thats mostly it.
Tried removing and pluggin every part back together, no result. Tried running each card alone for a hour, works fine, no errors. Temps are staying between 60-70 celcius, stock settings on the GPUs. Increased virtual mem to 30 gb. Tried swapping out the risers, still same results.
Would adding 4 more GB of ram do the work? Any good tips to how to troubleshoot this? Tried Google but nothing have worked out so far
Adding system RAM will probably not solve your problem unless you notice that you are running rather close to your current 4GB.
Have you tested both of your PSUs individually? For example, connect only one to the rig, and attempt to mine with one 1080ti and 2x 1070, then repeat for the other PSU.
