Tried to add memory but

Hello,

Ive tried to find help in some computer forums but it didnt lead to a solution so Im trying it here. Let me first state I tried all of this on a friend's advice and apparently it wasnt the right advice.

My motherboard is:

ASRock B85M Pro4

On it I put:

Crucial Ballistix Sport - Geheugen - 8 GB : 2 x 4 GB - DIMM 240-pins - DDR3 - 1600 MHz

(Geheugen means memory)
When I assembled the PC (with the same friend) about 3 years ago.
I put it in the A1 and A2 slot, which I just found out is not adviced, but it worked flawless for 3 years nevertheless.

Now today I bought 2 more memory sticks of the same gb size and the same mhz rate. My friend said brand did not matter. (and in the manual later, I found it says that it; does)

I tried all combinations.
ABAB, AABB, BABA. In all cases with 4 in the slots i get the message:



"Channel B did not pass CPU memory test"

Acting on advice from the forum I changed in my BIOS the XMP profile to 1. Since my old memory was running on 1333mhz instead of 1600mhz as well.
This did not change the 4 modules problem though.

Also when i put the old memory sticks in A1 B1 order it gives the same error message. While that is adviced in the manual...?

I seriously spent this entire evening on this and I dont get any further besides my PC almost not turning on anymore.
I powered on and off twice EVERY time, and then my screen would not turn on even tho the pc did. ANd later even the PC did not turn on at all anymore.

I put everything back in original position, did CMOS clear and now its working again.

Is this hopeless? Should I just get other RAM? But even though it says take a different brand, then why does my B channel not work in any given situation. Not even with A1, B2...?
