13 x GPU on 1 x Asus Prime z270-a anyone have 14+ working ?

[chilliefly]

Hey guys I'm wondering if anyone has had any luck getting 14-16 GPU running on this mobo. 13 works perfectly fine but 14th card makes the computer not post (black screen and keeps rebooting). As soon as I unplug one card works great.

Any help would be appreciated

You probably found the resource allocation limit of the mobo. Nothing much you can do about it without modded MB BIOS.
BTW 13 GPUs is nice achievement.

Hi,

How exactly did you plug 13 gpu to this mobo?

There are devices that allow one to effectively "split" a PCIe slot. For example, there are certain risers that allow you to plug 4 cards into one slot on the motherboard.

I'd personally call it good at 13. If your CPU/motherboard/etc. fails, the hashrate associated with all of your cards on that rig becomes 0 until you fix it. (Too many eggs in one basket, you might say.)

are you running windows 10 or Linux? I have problem with 7 card on this mobo (Asus Z270-A). Withi 6 cards work just fine but if I plug in 7 card, it try to recognize or install driver or something ( SSD LED blinking) for while then it go to black screen. Few time I have luck to boot into windows then it freeze. Anyone have any idea how to make the 7 card work on windows?
thanks

My rigs:
Asus Z270-A
Intel G4400
8gb DDR4
120gb SSD
2x 850watts EVGA PSU
7x RX580, 8gb Sapphire Nitro+ (Hynix memory type)

It's interesting. I found 4 to 1 and 3 to 1 on ebay.
3 to 1 is more expensive.

I would like to hear how exactly OP manage to get 13 gpu working on this board.

nobody managed to add more than 13 gpu on this mobo? exist a modded bios to manage more? me too stopped at 13 gtx, added 2 more but not work. Asus with b-250 can manage till 19gpu ; any idea to bypass 13 card limit?

i just tried with 14 gpu, no success. but it worked with 13 gpu verywell.

It could be due to the reduced number of PCIe lanes on Pentium and Celeron CPUs.
More CPU cores also helps reduce latency with a large number of GPUs to manage.

i have g4400. it support 16 pcie lines. z270 chipset support 24 pcie lines. so what can be problem? ram? 4 gb i will try with 8 gb(4gbx2). also i can try with i5-6500 but it supoort 16pcie lines too. i dont think it worked.

but i am trying to run 14 gpu. any help would be appreciated...

And I would try another processor from the I5 series, if possible. I have seen cases where more than 8 video cards did not start on Pentium and Celeron. And try to ask this question on the official forum

A celeron or pentium is enough for more than 8 gpu´s. I have several rigs running with 12 or 13 gpus and a g3900 celeron.
At the moment i planning a rig with over 20 gpu´s just for fun

I did not say that celeron or pentium are not suitable for 8 video cards, but I have useful experience. If you have tried all the BIOS settings and various operating systems, then you need to check with more memory and a different processor.
Are you making money or having fun? You understand that failures of video cards on a mining farm will give you a loss of profit.

Nobody did. But with only 16 lanes of PCIe available in the system problems can be expected as the number of GPUs
gets close to the limit. Some lanes are assigned to other devices. More lanes means fewer problems. The mobo was designed
to support a full featured Core CPU. It's false economy to go cheap with a CPU to support a dozen or more GPUs.

You speak the right words. I try not to farm more than 8 video cards, so I use the cheapest processors and 4 GB of memory. Hive OS uses a little more than 2GB of memory. I can even mine coins with 3 GB of RAM, but this is a small savings.

Thanks. I like 6, with a regular mobo, 1 PSU and a decent CPU. It can easilly be repurposed as a gaming rig,
HTPC or any other desktop.
