the equipment I'm working with:
-snip-

I have set the Allocate to 100% and have 60gb of virtual memory. The address is right and so is the wallet but no matter what I do when I run claymore miner U10.2, it runs for 30 seconds and crashes. It recognizes cards and pool and has all pools options set to 1. When it crashes the screen goes black and I have to restart the rig. Any thoughts? Any helps is appreciated.

Simple answer, claymore is pointing his devfee pool to nicehash and because nicehash is down, you rig is crashing. Solution is now you must use -nofee 1 to remove his fee. Your hashrate will be lower but stable.

The OP says, it runs for only about 30seconds, how the heck it could go on devfee mining as it doesn't start mining at all.

And yes, maybe your PSU is a little low too, I am using 6 rx 570 and my kill-a-watt says 1170W with dual mining.

This can be proven thru installing the GPU's one at a time, it sure does take time however for the sake of troubleshooting its may worth a try.

It's very obvious, the issue is the power supply, 750 watts is just not enough for x4 Radeon 570's to mine at 100% Allocation considering the fact that each card needs about 200 watts.
