I've got a B550 TUF board, have 2x 8GB DDR4 RAM in slots 1 and 2 and it works.

Add 2 more into slots 3 and 4 and I get a orange light on my board and it will not boot. Move Two stick to 1 and 3 and the same thing happens.

Any ideas?

Slot 3 is bad?

What exact lights are you seeing?

what does the manual say about ram?

are the second 2 sticks the same?

why did you go for 4 sticks over 2?

you also need to be more specific in the model numbers of the RAM and what CPU you are running

Manual says it should be good

Not 100% but 3200Mhz 2x 8GB DDR4 like my first 2.

I got two each as cheapest way to get to 32GB

DOA parts are not unheard of. Try one known-good stick on its own in each of the four slots.

Also take a good look at the slot for any pins that appear to be bent or otherwise damaged.

Happened to me before, I cleaned the ram contact point with white clean and soft pencil eraser and gave some it some air dusting.

Otherwise you need to do some troubleshooting by interchanging from other known working parts.

Matching pairs should be in the correct slots, for your first 2 sticks/kit that's A2 and B2 - per the recommendation in the manual.

If that works then test them in a1 and B1 to try and rule out mobo/cpu problems.

Are the two ram kits exactly the same spec voltage and timings wise? Is bios up to date?

Ok, for testing RAM issues, keep it simple.

Take one of your original known-good RAM modules, and place that into the slots 3 & 4, one at a time. This will identify if the motherboard is at fault if it throws errors.

If all is well at this point, then try your new RAM modules one-by-one in slots 1 & 2, since these were working with the original RAM. If that throws errors, then the new RAM is at fault.

It's simply a process of elimination.

If all RAM modules and slots appear to be working, then the only thing that may be causing the issue is a mismatch between the original and new RAM modules. Make sure they're as identical to each other as possible.

Oh and don’t have XMP enabled if you do. Should have it stock when adding new hardware.

I have a Gigabyte B550 board with 4x8GB of RAM and XMP on, it works fine. As people have said, do some testing with a known good stick of RAM, XMP off. Random things are bad - in the past I've had a new case with a faulty power button, faulty RAM, and a faulty power supply.

Yes the idea is to test with stock which means no XMP. Just as a FYI Gigabyte boards tend to have a higher vsoc by default, other manufacturers need a bump to that voltage especially when running 4 sticks.

I know this because I have a Gigabyte x570 and friend has a Asus TUF x570 both 3200MHz ram. He had sporadic crashing (bsods) on some games until he did memory testing and raised his vsoc to 1.1v manually to stay stable on two 8GB sticks.

And then theres me who didn’t need to touch a thing for four 8GB sticks, everything running fine on auto.

Looking at my B550 board. Should I be able to put a single stick into slot 3?

I've tried that with RAM which I know is working and it fails to boot.

you should be able to put a single known good ram stick and it should boot. if it doesnt reconfirm the ram stick in a different slot and confirm it works. this will prove its the ram slot.
