Question Dual Channel problems on ASRock Fatal1ty Z97 Killer motherboard ?

[1Speedy9]

Hi.

After I updated the CPU to an i7-4790, the motherboard will not accept Dual Channel. It beeps.

It previously ran fine with 2 x CMD32GX3M4A2400C10 and will still run with the two modules, just not in dual channel. I got hold of two other modules CMD16GX3M2A2400C10. I thought that then I could at least get more RAM, without them being in dual, but they are too similar.

I have tried different ways, but nothing works. Does anyone have a suggestion for what is wrong?

Welcome to the forums, newcomer!

Did you make sure your BIOS for the motherboard was updated to the latest? As for the processor upgrade, what were you on prior? With the new processor, check to see if the socket has any bent or broken pins.

If you can, please pass on images of the PCB number on the ram kits. Corsair is the only brand that uses multiple vendors to source their OC's for their ram kits. Aesthetically they look the same, from the same series but internally they are usually built with different ram IC's.

they are not from the same kit of ram. This is your main problem, mixing and matching rams.

Thank you.

I don't remember what it was called, I'll have to find it. Bios is uptodate.

I know they're not from the same (all 4), but they still fit together two by two, and I also think that even though they're not from the same company, I should still be able to boot the PC, but I can't.

So I expect them to be interpreted as the same, all four. Can only boot with two, and it doesn't matter which of the two I use, will only boot with one in A1 and A2, not A1 and B1, will not boot in dual mode, and don't understand it. (Pic later)

I know that the CPU doesn't support ECC, but that shouldn't be a problem, right?

How can I add/upload pictures?

Ram, and the old CPU and the new one.

I'll have to investigate later if there's a bent leg. It takes a lot 😔 Is there a way in the bios where I can "trick" the bios into thinking they're different. Thinking of setting them up, each one differently? So first boot it up with two modules, change the setup, and then try with the other two?
