I'm having a problem with a new MB I just got "gigabyte 970a-d3 rev3.0". I can't seem to get duel channel to work properly.
The ram I'm using is a 16gb 2x8 1600mhz kit.
The problem is if I install the ram to the recommend sockets for 2 modules DDR3_1 and DDR3_2 (white) rite out of the manual it will not run in duel channel mode no matter what I do. I've tried leaving everything default, I've tried setting the X.M.P profile and I've tried setting all the memory settings manually but no matter what CPU-Z reports the ram is running in single channel and DC Mode is blank.
Now if I install the ram to sockets DDR3_3 and DDR3_4 (blue), CPU-Z reports Duel Channel is working and DC Mode is Unganged.
The problem with this is my cpu cooler is to big and covers socket 4. The ram runs properly in socket 3 and 4 so I'm assuming its not faulty ram?
Is this by design with this MB or is it faulty?
970a-d3 rev3.0
AMD P2 980BE
HyperX Beast 16gb 2x8 1600mhz 1.5v

Ok think i have this sortted for you if someone else wants to add in feel free as i could be mistaken. It is your CPU not your motherboard. I was going to ask you what operating system you are using which by the way for future post please add in PSU, operationg system and so on the general rule is more info better answers.
Now back to your original question The memory controller on the Phenom II would run 4 x 4 gig sticks at 1600 but you are overloading the memory channel with 8 gig sticks. The motherboard does support it but you will have to update your processor to get it. The highest speed your CPU supports is 1600 i bet if you moved them to the last to slots and downclocked to 1333 they would work in dual channel. Why dont you try that and report back.
If you update to a am3+ cpu that controller should work at 1600 dual channel or 2T as CPUZ reports it.
ABSIC made a spefic thread about am3 cpu,s and ram speeds might want to read it to understand more and TY to ABSIC for his hard work in putting all thast info into a STICKY THREAD at the top of this forum but here is a direct link to it.
