Topic: Road to RX 570/580 7 GPU MINING RIG - page 4. (Read 83740 times)

I have RX 580 5 card are working properly by the driver trick.
But when i plug 6 th card (disabling 4g) Device Manager recognize 3 card and shows error for other 3 card. When i restart and enable 4G then system reset and goes to repair.
What could be the problem ?

My system:
- Intel G4560
- Asus Srix 270F Gaming
- 8 gb ram
- Corsair HX1000i PSU
- Sapphire RX 580 Pulse 4GB (Modded)
- Riser Cable Ver 3.0 30cm

Windows 10 64 bit installed.

I have the MSI-Z270-A-PRO, 6 RX480,
I have to do the same procedure to recognize the 6?
To manually replace and install the drivers. Will it work like this or only install the 16.9.2?

Wow it is very useful for newbie. The hash rate is increase and more stable than just copy the trap. I am so appreciated your help. Do you know who create this trap modifier? I want to send a little bit bitcoin or ETH to him.

here is my way how i did it with 7 rx 470 first install windows in uefi mode using onboard grapics with a usb pen created with rufus be sure you update your bios to version 1.7...

ok if windows installed connect 4 gpus and let windows boot ddisable onboard graphics now and connect monitor to gpu in windows disable updates be sure windows doesnt install its own radeon driver windows tryes to install 17.1.1 wich will not allow modded bios so i managed to disable windows update service and manually installed 16.11.5 beta wich is the last driver wich allows modded bios so it installed the 4 gpus the next reboot enable 4g decode in bios and set pcie to gen1 then windows will boot with 7 cards and the cards gets installed by windows automatic ... after next reboot you have 7 cards... i wasnt able to get it to work with newest drivers all of my cards have modded bios so no way found now cause it gets always code 43 after ati patcher i can only get 4 crads installed but you have to disable 4 g decoding so 4 crads gets installed listet with code 43 then ati patcher makes them to work but then if i connect the other 3 and turn on 4 g decode it wont boot didnt tryed for long now but if you have rx 400 series simply use 16.11.5 drivers to get 7 modded crads to work i heared also the rx500 series allows modded bioses the driver wont check for it signature but didnt test it cause i dont have rx500 series card... sorry 4 bad english...

Yes, I boot into Windows and I see all 6 cards (with 4g disabled).  I manually direct each card to the driver.   Upon reboot I can see all 6 cards in the BIOS explorer.  From here I have 2 options. 

1.  Enable 4G decoding which causes 2 aborted booting attempts with a third stating "Preparing Automatic Repair" and ending in a black screen.
2.  Leave 4G disabled which allows me to boot into Windows with 3 cards working and 3 without sufficient resources.


Or, I can remove one riser, and boot with 4G enabled and have 5 working cards.

I do have a 7th card, but unless it is an important diagnostic step, want to get 6 cards working first.  The 7th is new in box and can still be returned if needed.

So you make sure you are booting into computer and you see all 6 cards? Turn off auto driver updates and windows updates. Use DDU In safe mode, restart, Manual direct each card in device manager to the driver and install. reboot with 4g enabled. and peg 0 and 1 are gen 2. You have 7 cards right? Is the 7th card seen in bios?

I connected 6 of the up and all 6 are properly seen in BIOS.  The system would not boot with 6 however.

By chance when all 7 GPUs are hooked up can you go into bios and under board explore see all 7 pcie slots connected?

So, I have 7 RX480 cards and am running into the same problem.

If I put 5 of them in my system, and enable 4G decoding it works great.

Once I add the 6th I can boot with 4G decoding disabled.  (Of course then only 3 cards work and 3 have Error 12 - no resources)

Trying to enable 4G decoding with 6 cards will not boot from BIOS.   It will attempt to boot twice and on the 3rd attempt will display "Preparing Automatic Repair" and then...black screen.

Any pointer how you all were able to make this work with RX480s?

what is not good card for mining?

hmmm i thing it's not good card for mining

For that matter did anyone manage to run 7 gpu's on the z170 or 270 cards?

If so, I was looking into buying the msi z170 gaming pro carbon board. Anything I need to be aware of before buying?


Thanks

Anyone else having issues with 7 but not 6 gpus in z170a?

what memory? only swap the settings for 2:1750 not 1:1750,1:1875 etc...  only do the 2: memory timing.
you only use 1: memory timing for certain memory maker I am not sure but i would double check by googling it. I think its Samsung only.

Elpidia and Hynix is 2: timings

Hey there, I need some help with RX 570 Sapphire Nitro

I'm trying to flash it's BIOS. I'm changing the values of VRAM to increase hashrate by copying and pasting 1:1750MHz values over 1:2000MHz and 2:1750MHz over 2:1875 and 2:2000MHz.

After a system restart, RX 570 driver crashes and MSI Afterburner doesn't recognize the driver...

Anyone knows a solution to this issue and first of all, am I doing it right by changing those values?

I can find 6 after hours of troubleshooting this is what ive come up with.
My computer will detect 6 GPUS if the first pci slot is not connected. Connecting to the first pci slot my computer only detects 5 GPUS. I cannot get it to detected 7 GPUS when I have all 7 slots connected. Is it a bad slot or a setting in bios I'm missing?

I'm using windows 10 64 bit
Z170A Pro Carbon
RX 580 8GB

Nice Did you have problems making them work all together? You got 5 x 570s on the same rig maximum?

If you have a program like 7zip installed you can just "extract" the folders from the .exe.

Guys, you need to have your cards on stock vbios if you want them to have a chance of installing properly. Only flash them (and apply pixel clock patcher) once you can see them all working in device manager.

I spent hours yesterday swearing at my rigs wondering why I wasn't able to install Windows... Only to realise it would never install in uefi mode as long as the video card bioses weren't stock.

Could you share your bios, please?

In every case, I have a problem: making Windows recognize my 7 cards is not a problem (driver trick) but claymore and all the other apps don't recognize driver and close immediately (it must be an opencl problem, even GPU-Z won't start if I don't force it).
Do you have a solution? Tried pixel patcher but nothing. I have a Z170A Gaming Pro Mainboard.

Thanks!
