Ram Dual channel problems.

[iNs1337]

Hey, so im almost at the verge of buying new motherboard but i might as well give it a shot to ask you guys what do you think about it, i've read numerous topics about this problems, tried numerous solutions but nothing, RAM only works in slots 1 and 2, simply doesn't boot up in dual channel, tried cleaning my CPU socket with a light brush, checked on bent pins on the CPU and everythings seems just fine, didn't screw the heatskink on too hard either.
 Tried reseting the CMOS as well, no success as well, so i'm kinda out of options here and lost what should i try more.
 My computer: 
 Motherboard - Aorus B450 Elite V2
 CPU - Amd ryzen 5 3600 ( not overclocked)
 GPU - Sapphire AMD RX 6700 XT
 RAM - Kingston HyperX Fury 2400MHz CL15 DDR4 2x8GB kit
 PSU - Some corsair with 650 watts
 SSD - Samsung 980 Pro 500 gb (NVME) and 1TB of HDD

so you've tried slots 2 and 4 for both ram? And it hasn't worked in slots 3 or 4? Sounds like the ram slots are broken then. Does it boot when you put both slots in 1 and 2? (it shouldn't but it might)

It only boots while in 1 and 2 slots

So it does boot in dual channel? Or is this one stick?

 

If its only one then I would first try two in slots 1 and 2 but if that doesn't work I would try returning the mobo or contacting gigabyte support

That's the whole problem, dual channel does not work, only boots up with ram in slots 1 and 2, i have 2 sticks on 8gb of ram

Did you buy this board new or used? And can you contact gigabyte support as it sounds like you have broken ram slots (which you can't fix yourself)

Bought it new, like 6 months ago, will try contacting them

Either the board has an issue, or the cpu memory controller is bad. Slots 1-2 are on one channel while slots 3-4 are on the other. Your symptoms tell us that the slots 3-4 memory channel is down. 
 

I would probably pull the cpu first and take it to your local pc repair place to have them test it in another mobo (less of a pain than a full mobo swap). If it checks out, you know it’s your motherboard. If it doesn’t, RMA the cpu.
