Seems the issue was a riser, four xfx rx-570 running 2300+h/s under 600 watts as well.

Thank you all for the replies, I will try all of your suggestions and get back to you. This rig was running all four cards with nice hash for over 4 months, and never broke 600 watts.(I run it on a watt metter, its also running on 240) I run all the cards at stock settings accept the power, I run at a -25%. And  they are not modded but are running the update from radeon for vegas to help with hash rates.

the equipment I'm working with:
3 XFX RA 570
1 ASUS RA 570
WINDOWS 10 Pro
120 gb SSD
1 8gb RAm
1 2gb Ram
Celeron Processor
750 Watt EUGA power supply
Net gear wifi reciever (usb)
Bio-Star 189846 Tb85 motherboard

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
