DX79SR Channels A&B not working (dead memory slots??)

Community Manager

Hi, on my last trip to US I bought a DX79SR. I installed it with 64gb of ram but only 32gb are recognized: at the BIOS I can read "no memory installed" for channels A&B.

My config is:

Intel i7 3930K

Intel DX79SR

64gb Kingston Hyperx Blu 1600MHz (8x8)

2x SSD

2x HDD (Sata II)

Seasonic x850 Gold

What I've already tried:

- Swapping the memories (all of them are working on channel C&D).

- Updated BIOS to last version.

- Clearing CMOS (jumper in configuration mode, battery out... should I do something else?).

- Loosen CPU Cooler (Noctua DH14).

I think that's all... any ideas? I fear the slots are dead... Unfortunatly I'm from Argentina so I cannot send the motherboard back. Any help would be really appreciated. Thanks in advance!

PS: I've already contacted Intel support... they didn't give any solutions, they are supposed to contact me back.
