Help Dual Channel

[LMantegna]

I have a H87-plus (Asus), and I do not the works of dual channel ram:
DDR3 Corsair Vengeance Pro CMY8GX3M2A1600C9 8GB (2x4GB) PC3-12800 1600MHz CL9 XMP

The motherboard only recognizes the first two slots A1 and A2, B1 and B2, does not recognize them.

I thought it was a problem of dual channel, but, it is a problem of the slots B1 to B2...
I checked the pins in the socket, nothing broken.. What can it be?

If the board does not POST outside the case (for ruling out a short) with single RAM module installed in either B1 or B2, then I'd say to check again the CPU socket (use a magnifying glass or take a high res picture). If no bent pins indeed, then I would RMA both motherboard and CPU.

May be some speck of dust?

In both slots? I doubt it.

No Slots... in the socket

No. Have you tested the board outside the case?

No, I was going to do it...

My case: Scout II Advanced

A short could cause this kind of issues, that's why I suggested testing outside the case, on the board's box for example.

the motherboard is mounted to the case by means of spacers.. The only part in contact are the spacers and the lives .. (metal)

Is there a CPU cooler backplate involved?
Are there standoffs (between case and motherboard) installed?

1. Cpu cooler Intel (boxed)

If wanting to RMA, you would have anyway to take the board outside the case. It's up to you.

RMA too long, the other day I bent a tooth of HD AUDIO... I'll try the mob out of the case... clean up the socket..
