Help! Mining rig doesn't work!

[Winter Knight]

Hi guys

 

I recently built a Mining Rig with an old computer from my parents and 2 GPUs that I got from Aliexpress. The config is this:

CPU: Pentium E5300

Motherboard: MSI MS-7525 (Boston) (Motherboard website: https://support.hp.com/in-en/document/c01386897)

RAM: 3 Gb DDR2

Mining GPUs: 2 P106-90 6Gb (same chip as the GTX 1060)

PSU: XPG Pylon 650W 80 Plus Bronze

 

Nicehash does detect the rig, but it doesn't show the GPUs. I did my research, those GPUs should work on any PCI-E slot.

I thought that it was the riser cables, but I tried 2 different types, USB (most traditional) and a PCI-E 1x to 16x adapter, and both lead to the same result.

As far as I can tell, each component works individualy, but not when I put them together.

CMOS Batery is charged. BIOS clock is right.

The rig is connected to cable, so no problems there.

The PSU is brand new.

 

I ran out of ideas guys, does anyone knows how to solve this?

don't use NiceHash, they're not the best given their history

I think the problem here might be that the MoBo chipset doesn't have the ability to break up and assign the PCIe lanes properly.

Cheaper boards and chips like that one often only have 8-12 PCIe lanes total. so the 16x slot is running at 8x most likely and the other two slots may share a connection through the chipset or something.

I doubt there's a block diagram floating around for this.

Okay, that's bad, but this project of mine right now is more for proof of concept than actual mining, and I am currently using nicehash OS, a Tiny Core Linux distro, away from my data. Are there other free alternatives for Nicehash?

That could be an issue, but, in theory, I need a very small data connection to actually mine. Also, using one GPU also didn't work

It's not the bandwidth of the connectio I'm concerned with, more whether the chipset permits that configuration at all.

That is odd. Maybe there are some settings you need to change in BIOs
