Asus Z87-A Ram Problem

[kaiser_kaiser]

Hi, i just did a new build and my motherboard DIMM_A1 and DIMM_A2 dont work, if i use DIMM_B1 AND DIMM_B2 they work.
I bought 8 GB (2x4) of GSKILL RIPJAW X DDR3 2133MHZ and wanted to put in dual channel but i cant because the yellow slots (DIMM_A2 and DIMM_B2) dont work.
At the moment i am in single channel with the ram in the DIMM_B1 and DIMM_B2.
Tried Combinations:
DIMM_A1 only (dont work)
DIMM_A2 only (dont work)
DIMM_B1 only (work)
DIMM_B2 only (work)
DIMM_A1 and DIMM_A2 (dont work)
DIMM_B1 and DIMM_B2 (work)
DIMM_A1 and DIMM_B1 (dont work)
DIMM_A2 and DIMM_B2 (dont work)
Any Suggetions?
My Build:
Power:Be Quiet Pure Power L7 530W
CPU: intel i5 4670k
GPU: EVGA GTX760 SC
RAM: 2X 4GB GSKILL RIPJAW X DDR3 2133MHZ.
Motherboad: Asus Z87-A
CPU Cooler: Thermalright HR-02 Macho

Have you read through the manual and verified that this is not the normal operation while only installing two sticks of RAM? Some motherboards provide you with instructions on installing just 1, 2, 3, and 4 slots of memory in the manual!

Try in A1 and B1 or A2 and B2 that will put you in DUAL channel, if it boots into BIOS go to the advanced or tweaking section and Enable XMP and select profile 1, that should set them to 2133

SOunds like may be a problem with mobo or CPU (MC (memory controller) in CPU)....might run memcheck on each stick by itself (4-5 passes) to make sure don't have a dead dying stick...and make sure you have the latest BIOS

Agreed.

I found a bent pin, only if i rotate the motherboard i can see, i will RMA and see if the pin have solution.

I will reply news when i get reply from RMA.

 

[jkhoward]

That would do it. I am sorry for your frustration. Hopefully they will allow the RMA. Good luck!

Socket damage isn't usually covered by RMA - so you may need to bend that back yourself.

I know, when i said RMA but i really send it to the shop were i buyed. They are more qualified and experienced bending pins then i.

The pin was bend correctly and now the computer is working fine, thank you for the help.
Now just take 10 seconds to boot 😀

Great news! Glad everything is working now. Don't forget to chose the best answer!

your I5 cpu can only handle a max ram speed of 1600

1600 is but the native freq of the CPU, most all 4670K can generally handle up to 2666 sticks
