Topic: Solved: 6 RX 570/480/580 cards: Issues setting up rig PLEASE HELP! - page 2. (Read 727 times)

Thanks! Hope its didnt drive you insane.
I will disable 4G encoding and clean the drivers with DDU and then install all 6 cards (one at a time) and then enable 4G encoding at the very end.
Question: before I activate 4G encoding will all 6 cards be detected properly in device manager?

Follow this guide to change the settings in the Bios:

Set at least 16GB virtual ram in Windows. If the cards have a modded Bios you need to run the pixel patcher to bypass the driver signature check or you will have code 43 error for the cards in Device Manager.

Is the 4g (mining option when using more than 4 cards) enabled in the BIOS? If yes, disable it clean the drivers, reinstall them, make sure all cards work fine and only then reactivate the 4g option.
Today I actually went through the same procedure.

Hey folks,
I just got a second hand rig at a decent price and when I bought it I thought it would be easy to setup.
This is my first AMD rig (my 3 other rigs are all Nvidia) so please keep that in mind.

I am currently having issues getting all 6 cards detected.

Rig components are below:

3x RX 570 4GB
1x RX 480 4GB
1x RX 480 8GB
1x RX 580 8GB
All running Crimson 17.11.4 driver

Motherboard: ASUS H270 PLUS/CMS
CPU: intel Core i3
RAM: Hyper X Fury 4GB ddr4
HDD: seagate 1 tb
Risers: VER006C 6 pin PCIe
PSU: Thermaltake 1000w
OS: Windows 7 Pro 64 bit > upgraded to Windows 10 as per suggestions below.


Problem:
1) I have updated the BIOS and graphics driver (17.11.14) to the latest versions. But device manager showing issue with 2 of 6 cards (code 43).   Solved: Did a fresh install of Window 10. (not upgrade). using media creation tool. Then used DDU to do a clean "install and shutdown" after windows installed. Then installed blockchain crimson drivers and all 6 cards woking with tweaking in AB.  
2) Claymore v9.8 give Open CL 4 error- cannot create DAG on GPU. > Solved by setting a 20GB virtual memory. I forgot to click "set" the first time
3) Very low hash rate 13MH/s on 4 cards.   > Solved (see solution in 1))

Troubleshooting steps I tried so far:
-Tried blockchain drivers and they didnt help. Miner exits immediately.
-Updated motherboard BIOS to the latest version and enabled 4G encoding, PCI-e Gen1 (also tried Gen 2) and main graphics as PCIE.
-Removed all 5 cards and reinstall drivers with just 1 card. everything looked good until I added the 3rd card and launched Claymore which is giving Open CL error (windows installed fine)
-Then I installed the 4th card without any flag in windows device manager but Claymore is giving Open CL error
-When I tried installing card 5 windows didnt install drivers properly. Cant seem to get it correct.
-4G enabled after installing all 6 cards, Gen 2 PCie in Bios.
-Pixel patcher installed for driver signing.


Any help would be greatly appreciate.
