Done that also.

As stated in initial post, tried with windows reinstall few times (since it only takes 20 min or so) and played with different driver versions.

I always get consistent scenario.
Claymore works for few shears and then WATCHDOG: GPU (x) hangs in OpenCL call.

Already tried several.

Even tried running only 4 cards and then switching paces on motherboard and switching resizes.
In every situation always one card (usually GPU 2) will get hanged in OpenCL call and miner will get stuck.

So basically form hardware point of view checked every possible scenario to triple check every component.
I'm not sure if software troubleshoot will help... 

Hello people and good to be here.

I am new in mining but old in PC world.
Recently I bought my first rig to get hobby.

I’m currently running:

MB – AsRock H81 PRO BTC v2
CPU – Intel Celeron G1840
RAM – Patriot 4GB @ 1600
SSD – SiliconPower 120GB
PSU – 2 x ThermalTake 730W
GPU - 6 x Sapphire NITRO+ RX 480 8GB – (11260-07-20G) - STOCK BIOS/ no OC
PCI – 6 x Resizers x16 to x1 (USB)

So I set it up and am running Windows 10 and Claymore Dual miner v7.4.

PROBLEM:

After 5-10 minutes of running in ether single or dual mode I would get: WATCHDOG: GPU (x) hangs in OpenCL call. Miner will “restart” and will not start again.

TRIED SO FAR:

-   Reinstalling Windows 10
-   Running both single or dual mining
-   Running on stock drivers then 16.9.1 all the way to latest
-   Removing one or more cards
-   Switching PSU to run one to four cards and back and forth
-   Switching resizers
-   Running cards in both “OC” and silent mode (bios switch)
-   Virtual Memory set to 16GB+

I think a listed all.
So is there any solution to this issue since I’m pretty out of them right now.
