Topic: SOLVED: Trouble installing 2080 & 2080 Ti into ASUS B250 & H370 Mining MBs (Read 253 times)

You can also try Gen 1. I've done a dozen or so builds with the H370 Mining Master, most of which are exclusively 20 series and either gen1 or gen2 PCI-E speed solves.

I have the same problem with this board and changing to gen2 does not help me(( I need to run 12 * rtx ASUS TURBO 2080ti GPUs

could you share what else did u changed?

Solution/fix found: *Confirmed* Changing the PCI-E gen speed from the default setting of gen1 to auto and/or gen2 in the motherboard bios solves the 20 series install issues on both ASUS B250 and H370 Mining MBs.

Thanks goes to Someone_2 of the Ravencoin Community discord (mining section).

Except that, "For some reason, I can get up to x5 20 series GPUs installed on existing rig builds that already have up to x8 10 series GPUs that were already installed."  I recall that such installs often required multiple attempts to take, as in I'd have to try a different x1 slot of MB, but they eventually took, in the past. Stopped at x5 20 series because the rigs became x13 Nvidia GPUs, which is the Windows limit.

So, I've been able to install 20 series on x1 risers of both B250 and H370 Mining MBs of existing builds some weeks to months ago, but installing new 20 series GPUs on new/fresh rig builds on x1 slots has been 100% impossible from my end lately. I've tried adding one 10 series card to quasi replicate the past builds to no avail, even with a 10 series installed and used as video output to display, first 20 series GPU on x1 slot still won't install after dozens of attempts of trying everything under the sun that I can think of.

Recap:
I've successfully installed 15x 20 series GPUs into existing builds, this was 1 month or more ago tho.
12x 20 series are installed into x1 slots of B250 Mining Expert (quantity of 20 series per rig being x5, x4, x3, x1, each rig already had 6 or more 10 series installed)
3x 20 series are installed into x1 slot of H370 Mining Master (quantity of 20 series per rig being x1, each rig already had x8 10 series installed)

Remaining 2x 20 series are installed and running in new rig builds as x1 GPU builds successfully only when installed into x16 slot. Zero progress when trying to install any 20 series into x1 slot of new rig builds of either ASUS B250 Mining Expert & H370 Mining Master motherboards. I thought it was perhaps because of some Windows update that rendered recent 20 series installs into x1 slots impossible (as in over the past few weeks of attempts), or perhaps certain Nvidia driver versions, or a combination of both.

sounds like either motherboards doesnt support 20x series gpus or raisers do not. I would contact manufactures to be sure they work.

Lately, I'm finding it impossible to install new 2080 & 2080 Ti into ASUS B250 Mining Expert & H370 Mining Master motherboards. Trying to get new builds off the ground using only 20 series GPUs, and the only way a card will install is into the single x16 slot. When using a x1 riser, I get a black screen and ultimately a system crash requiring a hard reboot. Sometimes the system will reboot on it's own, only to repeat the cycle without completing a successful install by x1 slot. Cards are not defective. For some reason, I can get up to x5 20 series GPUs installed on existing rig builds that already have up to x8 10 series GPUs that were already installed (but that's after much trial and error by finding a slot that will take), but installing only 20 series GPUs into a fresh build has proven impossible from my end (and that's after dozens upon dozens of fruitless trial and error attempts).

Using latest motherboard bios (1206 for B250 and 1406 for H370).
i7 8700T for Mining Master.
7500T for Mining Expert.
16BG of RAM
Windows 10 Pro 64-bit
Samsung Pro 860 256GB to 512GB SSDs
EVGA T2 1600W PSUs
Riser versions tried: 009S-x, 009S-Plus, 009S, 008c
20 series brands on hand: Nvidia Founder's Edition, MSI, Gigabyte
Tried with no Window's updates after fresh reformat, and with all Window's updates.
Tried with latest Nvidia drivers and with past few Nvidia driver versions.
Multiple OS reformats from scratch.
Motherboard swaps.
CPU swaps.
Removed Ethernet cable for internet service during installs, and left with Ethernet connected on attempts.
Gave system over an hour for install to take on multiple attempts.
Only trying to install a single GPU by x1 slot before attempting a 2nd GPU, so leaving the x16 GPU uninstalled (unconnected).
Tried calling ASUS tech support without success. They opened a case and claim that their engineering team will try to replicate the problem. Weeks have passed without an update.
Sitting on x9 unused 20 series GPUs that I'd like to install this year if at all possible.

Has anyone else experienced and resolved this issue?

Background: I'm managing 29 GPU mining rigs that I built from scratch (275 GPUs). Currently, x249 GPUs are 10 series (mostly 1080 Ti), 26 GPUs are 20 series (x13 2080 /x13 2080 Ti).

Solution: Changing the PCI-E gen speed from the default setting of gen1 to auto and/or gen2 in the motherboard bios solves the 20 series install issues on both ASUS B250 and H370 Mining MBs.
