Question TUF B550-Plus RAM issue

[kiwis]

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

I added 2 more into slots 3 and 4 (same spec) 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. It's a brand new board.

Any ideas?

You should have the first kit in slots 2 and 4 and the second in 1 and 3. You say slots 1 and 2 work, that would give you single channel, with one kit installed you should populate 2 and 4, are you saying that doesn't work?

Also what RAM do have?

Are all four sticks identical? same mfr, model, size (GB), density, default timings? Typically, the best way to be positive of that is get all 4 as kit of matched sticks.

When you change memory configurations it's a good idea to reset CMOS to force the CPU to retrain memory. You may or may not be able to run XMP timings with all 4 sticks, it depends on their rated XMP and your CPU's memory controller quality.

Not identical but similar.
Doesn't matter, I put a single stick into slot 3 and it won't boot
