Question Motherboard doesn't detect full 4 slots of Ram

[Tuffi]

Hi,

I recently installed 2x4gb of ram but my motherboard won't detect them.

Here is my pc configuration:
CPU: intel i5 4570
MB: Asrock h87 Performance
Ram: 2x4gb Gskills + 2x4gb Sk hynix (installed recently).

When I try to boot I get a error displayed on my screen saying "memory channel A did not pass memory test". However if I check the hardware details using speccy or CPU-Z all 4 modules are detected.

Does anyone know what the issue could be?

Thanks,
