Hello,
I'm putting together a brand new build for my son with a total of four 8GB RAM sticks for a total of 32GB RAM. This is RGB memory.
The problem is whenever I populate slots A1+B1, the memory will only run at 2133MHZ.
I can only get the memory to run at full 3600MHZ speed if only A2+B2 are populated.
Here are my tests results with various slots populated:
A1+B1 - 2133MHZ
A2+B2 - 3600MHZ
A1+A2+B1+B2 - 2133MHZ
I updated to the latest BIOS and tried playing around with various settings such as enabling DOCP and manually setting the Memory frequency to 3600MHZ, but nothing will make slots A1+B1 run at full 3600MHZ speed.
I understand A2+B2 are noted as the recommended memory channel in the motherboard manual, and I have seen similiar recommendations on this forum to use A2+B2 because they are the "primary channel", but I would like to use a total of four 8GB RAM sticks, for a total of 32 GB.
I check the QVL (supported memory) list on ASUS website and the memory is supported, however it doesn't specify which RAM slots it will work in.
Is this a known limitation of slots A1+B1 in ASUS motherboards?
Has anyone successfully run four sticks of RGB RAM in these boards at full speed?
Update:
I did some testing with my other son's PC which has the same specs except for the motherboard and RAM.
My other son's PC has the following motherboard and RAM, all other specs are identical:
Motherboard: ASUS TUF B450-PLUS GAMING AM4
RAM: TeamGroup T-FORCE VULCAN Z 32GB (2 x 16GB) DDR4-3200 PC4-25600 CL16 Dual Channel Desktop Memory
I noticed that when we moved his memory (currently running at 3200MHZ) from A2+B2 over to A1+B1, his memory also runs at reduced speed - 2400MHZ.
We had the same results with both Teamgroup RAM and G.Skill RAM.
So it seems slots A1+B1 run at reduced speed regardless of the memory type.
Is this a limitation of ASUS motherboards or the AMD Ryzen 3600x CPU?
