Two Different Size Ram (8GB + 16GB) Stuck on DRAM POST LED

[JohnPaulDss]

First, specs:

 

RAM

2pcs 8GB
Manufacturer: Kingston HyperX
Model: HX426C16FB3/8
Capacity: 8 GB
Frequency: 2666mhz

Timing: CL16

 

2pcs 16GB
Manufacturer: Kingston HyperX
Model: HX426C16FB3/16-SP
Capacity: 8 GB
Frequency: 2666mhz

Timing: CL16

Motherboard
Manufacturer: Gigabyte
Model:  B360 Gaming 3

CPU
Manufacturer: Intel
Model: i5-9400F
Max Memory Size: 64GB
Memory Types: DDR4

 

GPU

Gigabyte Aorus Xtreme GTX 1080-ti 11G

 

Problem: My PC is stuck at DRAM POST LED LIGHT whenever I try to add the other Capacity Ram. 2x8GB sticks works on their own and also the 2x16GB on their own. But whenever I try to add the a 8GB on a 16GB it’s stuck on DRAM POST LED.

 

Background: I’ve been using 2x8GB set up for a long time and I bought a second hand 2x16GB with the same Brand, Speed and timing from a friend at a really low price. I’am really hopping to make things work since 48GB of total Ram would be sufficient for me (Cities Skylines). Both Ram with the same capacity works with each other. Also tried different slots and it’s working until I add the different Capacity one. 

Cleared Cmos

No XMP profile enabled (All settings on Auto)

Tried all the slots by itself (all working)

 

Working

A1: 16GB

A2: N/A

B1: 16GB

B2: N/A

 

A1: N/A

A2: 8GB

B1: N/A

B2: 8GB

Not Working 

A1: 16GB

A2: 8GB

B1: 16GB

B2: 8GB

 

A1: 8GB

A2: 16GB

B1: 8GB

B2: 16GB

 

Advance thank you for the help.

It seems that you haven't tried putting the same capacity sticks into the same channel, with 16GB in A and 8GB in B for example.

update the bios

I would say, check the mobo manual for sure to see how it should work. Update your bios could help too. When it works, be aware that you might not be able to reach 2666mhz anymore, because they are different batches and sizes of RAM, it's the disadvantage of mixing RAM.

Unfortunately still stuck on DRAM LED.

also tried:

A1: 16GB

A2: 16GB

B1: 8GB

B2: 8GB

Vice Versa

 

A1: 16GB

A2: 8GB

B1: 8GB

B2: 16GB

Vice Versa

 

I made sure that everything is seated properly and the contacts are clean every swap

 

I already google everything that I could think of. In paper it should work without issues. and read everything about memory from my motherboard manual

I already listed my 8GB sticks for sale since my friend still has another 2 sticks available for only $42 each. And so far since this is not working that’s gonna be my best option.

Goes to say that 13 will always remain the unlucky number.
