Hello everyone, I was hoping someone might have some insight for me about why my rig may be freezing.

I have
H97 anniversary mobo
4gig RAM
Cheapo CPU
6 MSI RX 480 Gaming X 8GB

The rig will freeze if I have 5 or 6 GPUs attached. The driver will constant fail, freeze, and sometimes reset the pc. The rigs will freeze mining Monero and Ethereum.

I have done a full system reset. Installed only the necessary drivers plus GPU drivers, set the virtual memory to 16gb min and 32gb max. What else may I be missing.


I appreciate any help.

Thank you.

i have noticed a similar issue with multiple of the anniversary boards. i build ETH and ZEC rigs for a friend (270x's) and with multiple rigs we have noticed an issue with adding card 6.

What ive decided so far:
1)could be not enough ram to run each card, i read somewhere that ZEC/ETH mining requires 1-2GB of ram per card (no idea if true)
2) could be your PSU cant handle all cards properly
3)My personal opinion, the anniversary board was selling far cheaper then the 'ProBTC'... I personally think there is something with the board model itself, as each of the rigs i have this issue with ... do it in the same slot (slot 3... the first after the 16x)

The thought has crossed my mind that I may not have enough RAM for 5 or 6 cards. However with this rig I have had 5 cards before and it was running perfectly fine. I had to take a GPU off because it killed itself and for about 3 or 4 months, it was hashing with 4 cards.  I add the 5th, I see some issues occurring. I add the 6th, and the GPU drivers begin to crash. 

My PSU should be ok. Haven't had any issues with it yet.

Your third point is not a bad theory. I can believe that.

I'll keep this in mind.
