Non-functional RAM slot

Solved

Hello,

I just received my PC and unfortunately I feel like one of the RAM slots, the 4th one (DIMMB2 I believe), is not working.

However, these are 2 identical RAM sticks "16 GB DDR4-RAM, Dual Channel (2x 8 GB), 3200 MHz, Kingston FURY Beast" and each of them works perfectly when I put them one by one in the 2nd slot DIMMA2. But when I try to put just one in the 4th slot, the PC doesn't start, with the "CPU" light remaining red.

The "DRAM" light stays red when I put both sticks in.

I hope there’s a way to fix this and that I won’t have to send the PC back. Does anyone have a solution? I’ve already updated the BIOS, maybe there's a configuration to be set there? :(

My motherboard: MSI B450 Tomahawk Max II

Hello,

You have a manual with your motherboard... The MSI website and your seller can also answer you, since you just bought it...

-- If your two sticks are exactly the same, with the same reference on the label, they should work... And they must be recognized in the BIOS, otherwise there's no point in going further...

https://download.msi.com/archive/mnu_exe/mb/M7C02v1.2-EURO.pdf

The memory architecture is in dual channel... Since you only have two sticks, and there are four slots, you can only place them on one channel, two slots, but not just any slots... See page 14 (French) of the manual...

Channel A is DIMMA1 and DIMMA2 and channel B is DIMMB1 and DIMMB2, and you must not mix the positions... and for it to work properly, dual channel must be enabled in the BIOS...

Check if all that is well respected...

Be careful, you need to turn off the PC each time to change the RAM...

Thank you for your response.

Yes, I know that you shouldn't put the RAM sticks in just any slot, but I think the last two slots are dead. Even when trying just one stick in these last two slots, the PC doesn't start; I have a red light on the DRAM. So I think they're just dead. In the end, I plan to return the PC; at least they can fix it because I'm out of ideas on how to solve the problem.

Hello
if you test each slot one by one with a stick
and one slot doesn't work
Then there's no solution
it's that the slot is dead
either you don't use it
or return it for warranty

Thank you for your response. Yes, precisely, the last 2 slots, when I tried them one by one, don’t work at all; I have a red “DRAM” light that comes on. So I think they are just defective in the end. The first 2 work well, but I can’t install my 2 RAM sticks together in these first 2 slots. I think it's time for a return for warranty service.
