[SOLVED] Newly installed ram not recognized

[nursgm01]

Recently added new 8gb ram stick to pc, but the total amout of ram remains the same -16gb.
I think its plugged in properly and works fine , because was tested in another machine.
Also its seen in "Dram status" in BIOS. I tried to move one stick from dimm_a2 to dimm_b2 slot
I'm using Ubuntu 18.04.3 LTS

Any suggestions are welcome!

Welcome to the forums my friend!

Presumably you added a new stick in and mixed it with an old stick? If so then firstly there is no guarantee that the RAM modules will work together, even if they work on another machine. RAM is only guaranteed compatibility in the form sold (from the same physical pack). So it could simply be the modules are not behaving nicely together.

• Have you installed them as per the motherboard manual?
• Have you tried running each RAM module individually in each slot to verify it's not a slot problem?
• Have you reset CMOS?

looking at your pic usually memory goes into "A2" & "B2" so take the stick out of B1 and put it into A2

The kind of combination of sticks you describe have no guarantee to be compatible together. You are free to do your own compatibility testing with no guarantees.

That sort of trial and error compatibility testing can be expensive if you prefer using random sticks.
