Can processor power affect dual-channel memory operation?

Question

Iron

Motherboard: Gigabyte Aorus pro
Proc: 9700k
Memory: HyperX HX432C16PB3K2/32 The
PC does not start and gives a memory error (diode is on) when trying to start the memory in dual-channel mode (on my mother these are slots B1-A1 or B2-A2). Everything works in single-channel mode in slots B1-B2, nothing starts in slots A1-A2 either. The motherboard assumes 8 + 4 pin processor power, I only have 8 pin connected. Could this be the problem?

Answer 1

nothing starts in slots A1-A2 either.

It is obvious that the slot is not working, or the processor channel

Answer 2

I would start with proper nutrition.
Dual-channel mode is the result of which you apparently need to achieve, but your main problem is that the PC will not start.
There is a possibility that one of the dies is broken.
To check (again, give the motherboard power first) use memtest86. Insert the strips one by one.

Answer 3

8pin power is more than enough for your CPU, especially without overclocking. The problem is most likely in the motherboard, I would start by checking the power supply with a tester on non-working slots, making sure that the correct voltage is VTT, VREF, VDD, VDDSPD, VPP.
