Working RAM Stick not properly working on new MOBO?

[gcwilliam98]

Hey everyone.
I own a kit of 2 sticks DDR4 Corsair Vengeance LPX 2133 8GB (16GB) That i was using on my Gigabyte H110M-H along with an Intel i5 6400.

I've bought a Ryzen 7 and therefore I had to buy an ASUS B350M-A.

Basically, everything works fine on the old gigabyte mobo. 
Not the case on new ASUS. One of the sticks is not working properly.

This is the scenario:
I can use the "working" stick in whatever slot I want. No incompatibilities. When I try to use the "buggy" one (alone) my pc wont even boot! 

When i try to dual Channel them (A1B1 or A2B2), BIOS in fact recognizes both sticks in a perfect match and info!! But it says my available memory is 8192MB! 
Old Gigabyte MOBO considers it perfect 16384MB.

Windows says I've 16GB installed and 7.95 usable (rest counted as Hardware Reserved) This is NOT windows related because the BIOS info about the sticks themselves is perfect with or without my SSD sata plugged into the MOBO. Also good to point out that on the old MOBO I get regular 16GB on Windows.

I have already updated BIOS and AMD Chipset, reseated the CPU and Cooler, didnt tight it too much cause i read that excessive cooler pressure could cause this

Any suggestions? I might get in touch with ASUS RMA tomorrow.

Remember, even the "faulty" stick works just perfect on the older motherboard and the new motherboard refuses to accept it, even though it shows in BIOS when in dual channel.

Are they in the right slots on the motherboard according to your mobo manual?

Yes sir, the manual suggests me to use A2B2. But even if it was A1B1 it should work. BTW, If i mix them (A1A2 or B1B2 to try to run as 16GB single channel) pc wont boot either.

Yeah no if it says a2b2, that means a1b1 probably won't work.  Run it how the manual says, because it was written that way for a reason.  The slots are probably designed not to boot in a mix of things because of how most motherboards work and how dual channel works.

Absolutely right. But just in case, have you read it carefully? The "Faulty" stick actually works in the old MOBO, single or dual channel. But on ASUS, this particular stick won't boot in single and there's this glitch on dual channel. I don't know if i should reach Corsair or ASUS RMA

Have you tested both sticks by themselves in slot a2 as it says here? This picture is from you motherboard's manual on this page https://www.asus.com/us/Motherboards/PRIME-B350M-A/HelpDesk_Manual/  EDIT: are you on the latest bios version?

Yes, stick 'X' is OK, it performs perfect in any position.

stick 'Y' is NOT ok, it won't boot if alone in ANY position.

 

In dual chanel, i can Boot, BIOS WILL detect both sticks, equal timing, equal frequencies, everything.

 

But it counts my memory as 8192

 

On my Gigabyte H110M-H, Both sticks work just fine.

 

I've already updated BIOS and Chipset

Just for clarification, the second stick doesn't work in slot a2?  Have you updated your bios?

In the bios, when both sticks are detected, what do the ram settings look like? Can you get a screenshot?

I cant now, but i ensure you that it shows PERFECTLY equal. Latencies, frequency, voltage is set at 1.2V (which is the correct for these sticks).
UEFI has a section where i can select A1,A2,B1,B2. Since they're plugged in A2 and B2, when i Select these channels in the combobox it shows exactly the same info, byte by byte.

Sounds like a windows issue then if it correctly detected when it's in the right spots

As I said in the post, not sure, it doesnt looks like a windows glitch because I first tested it with the SATA cables unplugged. Windows looks pretty much just a consequence of the glitch origin, which I'm affraid it's the MOBO, since memory works fine in other MOBO
