Complications over new PC build.

[VladAlex24]

Greetings,



Recently I have assembled my new PC, but I have faced one problem.

The problem appeared just after assembly, as I have turned on the pc - I would get "no signal - going to the sleep mode" on the screen. At first, I thought it was an HDMI cable or monitor issue, which it was not. At some random point, I have unplugged one of the Graphic cards and one of the RAMs and place the last one on the 3rd slot (also worked on the 4th but did not work on 1st and 2nd (originally on the first launch was placed on 1st and 3rd )) and it suddenly worked.



But, even though it works well, and with those specifications I have it is good enough, but I would actually wish to install second graphics card and another RAM, and if I do this, my PC will do the same as before - it will be turned on, but no visual image on the screen, no signal.



So, to give you more clear details I would attach my specs:

Motherboard: MSI x470 Gaming Pro

Processor: AMD Ryzen 2700x

Power Unit: EVGA 750 GQ

Graphics card: Radeon RX580 (2x) works only with one (any)

RAM: HyperX Fury DDR4 16GB (Kit 2x8GB) 2666MHz CL16

Monitor: Philips 276E 4K

To clarify, I was assembling everything myself and I do not have a large experience in it, though I took all the necessary precautions.



So if somebody ever faced something like that or possibly know a possible solution to the problem - I would love to hear them.



Thank you.

The RAM should go in slots A2 and B2 per page 6 of the manual. The motherboard does support crossfire so you should be able to use two RX 580s. Once you've got the RAM working, try putting your second GPU back in.

Thank you for your reply,
In the manual, I got the recommendation of RAM placement was actually A1 and B1 (which I have named just slots 1 and 3) and in this variation, it did not work.
Also, I tested it in many variations (taking out graphic cards, swapping them, trying even without and placing RAMs in different slots). The only variation it seemed to work is RAM in slot 3 or 4 (only one) and one Graphics card.

The manual states A2/B2 for two sticks of RAM.

Oh sorry, you are correct, it is indeed A2 and B2. But I still tested it, though it did not help.

Also check page 26 of the manual to make sure you're looking at the DIMM slots from the right orientation.

There is a small text label on which one is which. So, I was checking those when installing RAM. But my question is - why exactly could this be a problem? It is hard to wrap my head around that fact that out of 4 slots for RAM memory only 2 of them viable and only in a specific order And as stated before, I tried almost all possible variations, but only singular RAM can work only on slots B1 and B2.
