I need some help

[Fear Fuzion]

So I recently purchased the G.SKILL TridentZ Series 16GB (4 x 4GB) 288-Pin DDR4 SDRAM DDR4 3200 and when I use three sticks my PC boots up fine and reads all three but when I add the last stick into the fourth slot my PC turns on and the LED's turn on but then it boots off and continues to this. Here are my PC specs at the moment, i7 5820k, AMD R9 270x, and my motherboard is a Gigabyte X99-UD3. Before I purchased the ram I checked pc part picker to make sure my system was compatible and it said I was all fine. Does anyone know how I can fix this issue? I tired to raise the voltage but when I boot my pc it gives me an error so I have to boot into the default profile.

You might have a bad stick of RAM, in that case, RMA it.
But did you try different sticks in different slots. Than you can see if the stick or the slot is the problem.
If that stick works fine in a different slot it's your Mobo that has a problem

So with the forth stick it does not boot at all, like no bios screen?
Also try it in other boards if you can

[Gravemind]

Might be a faulty stick, it happens more than you'd think. Or a dead RAM slot on your motherboard.

So yeah I literally tried all ram and all of them work but when I try to use all four the pc wont boot for some reason, maybe one of them is bad?

yup when all four is in no boot no bios screen, and I don't have another mobo

Try the suspected bad stick in another slot. If it works, then it's the 4th slot. If it doesn't, it's the stick.

It could be both, however unlikely.

I hope its not a dead slot on my mother board lol

ok I will try that now.

I dont think this should be the problem because the three sticks work, but your motherboard says it does not support memory speeds higher than 2800 mhz

You will have to get someone to check if this is even possible without breaking crap because ive never overclocked but perhaps you can try running the three modules at a lower frequency then plugging in the forth

EDIT: It could even be an issue with bandwidth locking. I assume that during post it attempts each slot by asking "how much bandwidth does the ram in this slot need" and allocates it, and if it cant lock in more than three due to the board not supporting so much bandwidth then it refuses to post?
Just a thought, btw im in no condition to even afford a decent gpu let alone ddr4 ram or overclocking so im not responsible for anything blowing up lol

Hey man thanks for the info, I appreciate it. I think I'm going to RMA the ram and just stick to 2 sticks at 16gb

Guys update for some odd reason I switched the ram sticks around into different slots and now my PC is up and running? That's so weird lol
