card detected problem

[marcelll]

Hi guys,
I have big problem and I don't know what I can do... My miner have 13 cards but after some time Miner using only 12 cards and no 13 cards.. I testing all cards solo and risers too but I found no hardware problem. I tried update ethos and change overclocking and suddenly card number 13. started work but just 1 hour then disappeared again..
Next problem. Earlier this miner mining 14mhs on 1 card.. Now 11.2mhs.. where is a problem? And where can I reduce mhs?
miner:
13 x AMD Rx 460
Asrock H110 probtc
4 Gb ram DDR4
Intel 1151 3900
SSD 128-256gb
13 x Riser
evga 1600 w

Your mining rig is probably encountering errors and is crashing. When this happens, your computer restarts with the faulty GPU no longer active (you can verify this in device manager too). To fix this problem, make sure you are not overclocking your GPUs too much. Make sure you also BIOS mode your GPUs, seeing that they are AMD, because they might get too hot and crash due to high temps.

I decreased mem on 1900 and result is 13 cards is loaded and functional but cards mining only 11mhs and earlier miner mining on one card 14mhs. Where is problem? overclocking is same as before..

I reboot miner And again only 12 cards functional. I reboot again and 13 cards functional.. what Is this...

Make sure you know which (physical) card it is that is flakey, or is it random?
Move that card to a quarantine rig and see if the situation get better.

Does the issue follow the card, riser, USB cable, power, or just the fact that 13 suddenly is an unlucky number with the bios?

1600w maybe its burned. check your Power connector.

[marcelll]

Power connector Is ok. How Can I reduce mhs? Without cor/mem overclocking?

guys, how much I can overclocking Sapphire rx 460 2Gb 2 fans 6pin ? Now I tried this config:

1900 is on the high side. Try lowering this a bit more. Also your power should be negative (-). Profitability lies in reducing the power consumption not in increasing it.

Like i said in my previous post, you have to find out first which GPU is causing the failures. Once you see what GPU is bad then you only need to change the settings of that GPU.

Try to reinstall the drivers for your GPUs. Had the same problem with one of my cards (others were hashing 30Mh/s and the 1 was only doing 10Mh/s). Reinstalled the drivers and everything worked.

[marcelll]

How much cor,mem,pwr And fan you recommend me?
