Ryzen Build - No Video

irh1 · 16 Sep 2017 at 20:34

Any thoughts?

Ryzen 1600, Corsair Ram (on QVL list), Asus Strix B350-f Gaming, old GTX 590

- Motherboard lights up, fans spin, no video.
- Tested video card successfully in different PC
- Sent back the motherboard, got a different one - no difference
- Tried different card (even older GTX 295)
- Tried ram in different slots
- Tried an alternative (known to be working) psu- You can't seem to update the BIOS (which gives better RAM stability) without having a video output

If it helps, plugged a motherboard speaker in and it gives a long beep followed by three short ones, and then a fourth after a bit of a gap - three beeps is 'no vga detected', four is 'hardware failure'. Got the same pattern with both boards

Do Ryzen only work with latest video cards?
Otherwise it is down to RAM or CPU; do I just return both?
At a bit of a loss ....

I would get the motherboard manual out and slowly go through the install process again to make sure you haven't missed anything.

I managed to miss out the power cable to the motherboard first time round :eek:

I would pull the cpu and check the pins.

Thanks for swift reply. Re-checked the manual. Checked the pins both times before putting into each motherboard.

What corsair sticks have you got? Have you tried unplugging everything, except the essentials (no drives / audio / USB / front panel ect) and only using 1 stick of a ram at a time?

They are CMK8GX4M2B3000C15
Yes, have tried one stick at a time, hard drives are unplugged. Just unplugged HD audio and front panel USB, but sadly still no video output

It's sounds like you are just unlucky your Gpu won't work with The Ryzen setup you have. If other Gpu' work fine and that Gpu works fine in other machines then it seems that way.

Is there a bios update for your Gpu ?

So it could be the gpu is too old? Googling for a bios update for the card took me to TechPowerup.com; the thing that immediately stood out is "UEFI supported: No", suggesting perhaps that the ryzen/rog b350f setup relies on UEFI only (the other PC we are testing with is a Z97 so old enough that it supports pre-UEFI)? Or am I grasping at straws?
