[Problem] I can't connect more than 2 card ( Code 43 )

[Morxander]

Hey Miners,

I have a rig with 3 cards ( Vega 64 ) running on Windows 10.
I can connect the 3 cards on the motherboard directly but I'll face a heating problem so I decided to take one card out and I connected it with a USB Riser.
It's works fine for couple of minutes ( sometime hours ) then the mining software stops and If I ran it again it doesn't mine so I have to restart my machine and when I do that Windows can't read the third card and it shows a yellow triangle with Error Code 43.
I changed the USB Riser and still the same problem, I tried to switch the cards and the slots and everything and the problem is always there.
I have ASUS Z270E with 4 GB Ram and I increased the Virtual Memory but still no luck.

Think you'll need more than 4GB ram installed - 8 or 16.

4gb is enough even for vega, @topic dont connect your riser with sata to molex.

Yes I think 4GB is enough because I checked the memory usage, My riser takes sata OR 6 pins for power and I am using the sata cable to power it.

enable 4g coding, disable vga onboard ...

Maybe, but I once had a horrible few weeks trying to build a stable Vega rig with 4gb.

Anyway, aside from that check power connections, especially the risers, and as treanski says avoid sata if possible. If not possible use one sata PSU output per riser max.

Get 8 gigs total. Connect the cards first. Make sure wake on lan is enabled in Bios. Update to the most latest (stable) driver available. Uninstall the card from your computer hardware management tab. Make sure you uninstall the driver as well as the hardware. Then redetect your hardware and do the autoinstall.

Should fix it.

There was such a mistake with one card that I just did not do, starting with drivers and ending with the firmware of the motherboard, but it did not help, I had to carry it back to the store and after long disputes and card checks, it turned out that it was Zavadsky marriage
