Title: AMD card not detected. 6 card only 5 detected Post by: pornluver on July 05, 2017, 12:33:00 PM How do I even trouble shoot this
- motherboard A88X-G45 - 1 psu 650watt - 6 VGA 460 sapphire. 6 fans in VGA all running and only 5 detected I wonder why my VGA only 5 detected ? I try to turn off claymore. Result is all fan are on despite GPU 0%. Another miracle. So it's hard for me to know which card is problematic Only 6 cards show up on device manager, wattool etc. All fans are running irrelevant of whether I am using them for mining or not. Something is just wrong. I suspect the problem is because I am using my PSU sata power cable to power 4 sata risers. I am using rx 460. My PSU have 650 watt capacity. The whole rig need only 350 watt last time I check. The 6 pin power is not used because of this.

To solve this issue I had to install a patch for windows 8. I was using windows 8.
Anyway the psu you have is too small for 6 cards. The consum for 1 card is about 120-150W in full load.

I am using windows 10 Does the mothoerboard itself have drivers? Do the fans keep running too?

Unplug all the cards, then plug 1 in at a time until you find out which one has the problem. Then try another card in that riser AND try that card in a different riser.

The card and risers work well on asrock btc. The problem is also made difficult by the fact that all rx 460 fans keep running. So I can't tell which one isn't detected. That is. Even if claymore is inactive, all the fans are doing 1200 rpm. All are sapphire rx 460. I wonder if it's the card or the mobo or what?

It's rx 460 very low power. What patch did you use? Title: Re: AMD card not detected. 6 card only 5 detected Post by: daniweb on July 06, 2017, 07:56:30 AM try this:

check all connection check and swap the usb cable check and swap the riser i had that issue before and it also can cause memory error with some not so good riser |
