Question New build - DRAM and CPU red fault light - No display

[Kusho50]

ASRock B550M PRO4 AM4
AMD Ryzen 7 1700X
CORSAIR Vengeance LPX 8x4 32 GB 3200 DDR4
Nvidia 2070
MSI - MPG A850G PCIE 5.0 850 Watt power supply
COUGAR DuoFace Pro RGB Black ATX Mid Tower Gaming Case

New build, the CPU is an older CPU I used in another PC, but upgraded to use Windows 11. The RAM is also from a different PC and worked fine. I had another stick of DDR4 from a different computer but when I install just 1 stick of ram, either the Corsair, or the other ram. Not sure what that was. Came with an Alienware older pc.

Get DRAM and CPU fault light, and no video. Tried with and without graphics card. Have faults either way, and no video when we add the video card.

Tried both ram. Tried using a different 8-pin connector on the power supply, and a different 8-pin cable. Cable says CPU on it, so I think that is the correct cable.

Unsure what else to try.

When I power it on, all fans spin, CPU fan spin, etc... and all wires apear connected correctly.

Thoughts?

Hi Kusho,

If you say the RAM sticks are different, check if you're not applying both sticks to form a dual-channel. You must then choose a different RAM slot to accommodate the second stick.

Try to update the bios , that chips not supported forWin11 doesn't mean it wont work tho.
do you have TMP.2.0 enabled and secure boot is enabled ?

seems the 1700x is not supported by that motherboard. It only supports the 3000, 4000, and 5000 CPUs
... And I was trying only 1 RAM stick at a time. This motherboard not supporting the CPU I believe is the issue.
... And I can't get into the BIOS to update it. I get no video from the system.

[Verify that I found the applicable manual.]

Review the entire manual to review what was done and pay attention to all fine print, caveats, etc. Watch for some error of omission or commission.

First, confirm that intended components are supported. Also visit the manufacturer's website to check for updates to the QVL (Qualified Vendor's List).

Second, ensure that the installed RAM is correct: both supported and installed in a supported configuration.

Third (with power off and PSU unplugged of course), disconnect and reconnect all connectors, RAM, cards, jumpers, and case connections. Leave the CPU alone.

No one want to force anything especially with respect to a new build. So what appears to be properly connected may not be. You may discover that something all of a sudden just seems to go into place much more smoothly and firmly.

Just take your time, no need to rush, Work in a clean well lit area. If something seems amiss, then stop and resolve before proceeding.

Thanks for the input guys. this was my issue. Ordered a 5800x (which is supported. Also verified the RAM is also supported. So the new CPU should fix me.
