8x GPU Nvidia Mining Rig With Asus PRIME Z270-A - Crypto Mining Blog
Does anyone read the Mobo manual?
There it says about M.2 settings and interference with SATA drives and the PCIe16x.
Read the damn manual.
The correct steps are:
-don’t install any GPU, just use the mobo’s video port (CPU with graphics required).
-use SSD in a SATA port free of interferences (read manual).
-upgrade bios to last ver.
-reset bios settings to default and restart.
-in bios set Above 4G decoding enabled, let PCIe on auto, put M.2 port on PCIe mode, DMI on auto.
-fresh install win 10 pro x64 (last version from a stick made with the utility provided on microsoft site – on download windows 10 page).
-update win 10, restart, disable windows update, hibernation, defender, sleep mode for system and hdd, etc, and UAC account control to off.
-install first card with pcie riser.
-start, install nVidia drivers (no need for experience, hd audio pr physix).
-open task manager and watch nVidia processes finish their work (CPU activity 0).
There will be nvidia installer, nVidia containers etc. They install your card.
-shut down the rig.
-install second card. Start the rig and wait for nvidia processes finish.
-shut down and repeat for each card.
The order of installation is not important. Do not unplug the installed cards, before to install new cards.
After the last card, restart and now you can install the utilities, afterburner, gpu-z, cuda, miners. You order of the cards as seen by the system is: 1.the 16x slot, 2.the 8x/4x slot, 3-6. 1x slots.
In GPU-Z you can see the gen(version) at witch each card connected. If it is set in bios gen 2, gen 3 or auto, you can see some of them connected at gen 3, others at gen 1.1, or some at gen 2 and others on gen 1.1. So the actualy settings dosen’t really matters. I personaly experimented this with pcie risers gen 007c on Asus Prime Z270-P, with nVidia 1060 3GB cards from variois brands. So even if you set all to gen 2 or gen 3, they will link at their speed anyway; and more… after each restart, they can link on other gen. So… I tink you can forget the pcie settings. Only the Above 4G is important. Of course, if you use older risers, or some cards are not detected, you csn put pcie on gen 1, just to be sure there is not a problem. I found instead 4 risers out of 6 as defectiv/ bad, even thoug they had thiers leds on. If you can’t see a card, just connect the usb cable from one that is visible in the system to it, of course with the rig shut down. If you can see it installing, there is a problem with your system. If it dosen’t install, the riser is bad. Unpluging an working card and connecting a new one with the same usb cable, it gives you the same number of installed cards, so the system has to detect it, if the riser is good. When switching usb cables, you don’t need to unplug the power from the desconected card or riser. You manipulate only the usb cables. The old card stays without an usb cable. I think I explained it very clear :))
You can have a total of 8 video processors in windows 10, the cpu graphics included.
If you use the cpu for connecting the monitor, the system is more stable when overclocked, you can handle it better and oc more…. but you can’t add the 8th card. Is your choise. If you take the risk and install the 8th card, disable first the cpu hd graphics in bios and use the card pluged in the 16x slot for monitor.
One problem I couldn’t solv yet: with each card added, the hashrate drops for all cards. I used XMrig for mining cryptonight coins… etn, xmr… With 1 card I had 480 H/s. With 6 cards I have 350 H/s on some, 420 H/s on others and between on others.
If you find this usefull, thank me in BTC:
