mining rigs keep crashing

[candiceNP]

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.

Is that 4 vid. cards, if so I suspect power issues, start with 1 card, if ok then 2 etc. Besides that remove the 2GB stick, adds nothing but chances of mem errors.

Are your GPU's modded? try to install one GPU and make it work before adding the 3 GPU's, this is to isolate possible faulty hardware or driver. from the looks of it might be a riser / drivers or power issue.

 750 WATT Power Supply will not be able to handle 4 cards at once, don't forget they are AMD cards too. Radeon 570 uses about 200 WATT per card at maximum load (Tom's Hardware) 200 * 4 = 800, you are losing there already. Not to mention that the other components in the system has to use power as well.

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.

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.

or maybe too much overclock/underclock

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.

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.

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

try to upgrade the psu

Will system get affected if we start mining any coin?

[Deathwing]

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

A relatively good performance with -25% also good job on finding the faulty riser, it could have hurt the motherboard and rest of the GPUs if it wasn't fixed.
