Thanks for your answer. That is the way i have them connected. Two cards in one data power and one alone


Also thank you for your replay. But this motherboard is supposed to support 6 gpus and specially for mining!!!. I am new to this so i don't know about this software... i will research

Hello. I just got this motherboard but i have the same issue as many people. I got 5 gpus but only shows 4.

I read some information over website and it said update the bios and change the option "enable 4g decoding"

Where is this option for this motherboard... i navigated all over the bios with no luck... please help me... or if it is other solution for me to get the 5 working

Hello. I am new at the forum and mining, and let me thank you because i have learn a lot because of you comments.

I have almost the same problem. I can't put 5 gpu's (rx 570) to work stable. 4 works apparently fine because it will run for two days non stop at 27 m/h each. But with 5, it doesn't work stable. Could work fine for about an hour or three, or a day, before it freezes. 5 days has been the longest. It always would freeze - it says one gpu1 is o.ooo m/h and driver error. GPU1 is the one card connect to hdmi on the slot PCIEX_16. Sometimes throw this error: Watchdog GPU1 hangs in openCL call, exit... then freezes. After reboot, one card loses the patch. The driver i am using is 17.4.3 with patch. But after it hangs, one loses the patch and windows won't recognize it. i have to take and put again the patch several times till it recognizes, which i find it ridiculous and it should not be.

What i have done:

Changed the memory clock... nothing

I did the trick rx 400's 16.9.2 windows 10 64 bit to rx 500's 17.4.3 windows 10 64 bit... worst... claymore hangs when it opens with advises of driver errors.

i install the one of the later drivers, 17.5.1 which doesn't need the patch... nothing, it hangs

changed the virtual memory up... nothing

the risers are new, and changed orders of gpus... nothing

I am losing my mind. i am beginning to think it is the rig configuration, as i have read that some motherboard won't run all the gpus, even is they have the slots to do it. So i want to ask you if the rig's configuration it is ok for running 5 gpus without problem:

motherboard: Gigabyte AM3+ AMD 970 SATA 6Gbps USB 3.0 ATX AM3+ Socket DDR3 1600 Motherboards (GA-970A-DS3P)
cpu: AMD FD6300WMHKBOX FX-6300 6-Core Processor Black Edition
5 x ASUS ROG-STRIX-RX570-O4G-GAMING OC Edition GDDR5 DP HDMI DVI VR Ready AMD Graphics Card, elpida memory
4GB ram
PS 850 watts
windows 10 64 bit

If this rig's configuration is ok... what it could be happening? please help!!!! and sorry for the long post
