I have 64 gig of Corsair vengeance ram. I put it in MB and it wouldn't boot. I took out 32 and it booted just fine. I then took out that 32gig and put in the other 32gig and again it booted . Do I need to turn on something in the bios to get it to see the other 32 gig?

my system
ASUS TUF B360M-PLUS GAMING S LGA 1151 (300 Series) Intel B360 HDMI SATA 6Gb/s USB 3.1 Micro ATX AMD Motherboard
Corei7-11900k
GeForce 2060
64 gig DDR4 Corsair Vengence ram

If you have two memory sticks, are you putting them in the right two sockets?

the only way my board will see the 32 gig is if I put them in A1 and A2, if I put them in A2 and B2 the PC won't post it just keeps cycling. If I put in the other 32gig same thing happens, will not post. As stated if I remove the current 32gig and put the other 32gig in A1 and A2 then board posts. The board shows the correct amount and type of ram installed no matter which 2 of the 4 sticks I use so I know the ram is all good. Thanks for the response.

Memory in just A1 and A2 will be half speed I'm pretty sure as it's not interleaved.

Just showing the memory is one thing, but did you run a full memory test? If not, I'd try something like MemTest86 and do a couple of passes on the memory.

I have Googled and reread my Manual and can not find the code displayed, shown when I have ram in slots B2 & A2. the code displayed is 3A. Can anyone tell me what the code is.

I am not sure I phrased my issue right, I want to put the full 64gig ram in my motherboard but it will not boot if all 64gig is installed. It just starts cycling codes over and over.
