Issues Installing More RAM

[joshuamarquez1995]

I’ve built this computer myself a couple years ago. But I’ve run into a problem. When upgrading from 2x4 to 4x4 (using all my ram slots now) the computer power cycles constantly without ever allowing to go to BIOS. Stays on for 10 seconds then off for 10 seconds. Now here’s a concerning thing I’m discovering. When I have any RAM in port 3 or 4 it’s doing the power cycling as mentioned before. Boots fine when RAM is in 1 and 2 or just 1 or 2. When ever you have a combo including 3 or 4 it’s power cycling. (Like 2/4 or 1/4 or 2/3 or 1/3/4 and so on) I know all the RAM is good I’ve swapped out all the RAM with old and new and when I’m ports 1 or 2 or 1/2 boots just fine. They are all the same RAM cards with same voltage and DDR4. I have a Gigabyte GA-z170 motherboard and 2 hyperx DDR4 2x4 8Gb RAM making 16gb RAM. With intel I-5 6600k processor. Haven’t messed too much BIOS settings (honestly don’t know what I’m doing there) Anything you guys have to say or offer will be awesome!

What happens when *only* slot 3 or 4 is populated?

What memory do you have, specifically? Even what appears to be identical kits may not 'play nice' with one another.

The Hyperx DDR4 2x4gb RAM 2133mhz. I have 4 sticks total making 16gb. When putting just slots 3/4 just power cycles

Memory is guaranteed to be compatible in the form sold. There are no guarantees for other combinations you happen to come up with. You are free to do your own compatibility testing as the combination you have described is one where the memory has never been tested together.

Workarounds for getting extra memory to work:
Lower DRAM frequency
Relax DRAM timings
Increase DRAM voltage
Lower CPU multiplier

I will try that Calvin. Any recommendations on how far to relax the timings or increasing voltage. I tried increasing DRAM voltage by +0.05 and it didn’t see to work. Would you need to see screen shot of timings to help?
Thanks you!

It looks as if you are already at the lowest clock frequency possible - 2133MHz. You might post the memory part number(s) when you have a question about memory.

You could try 15, but you would probably need to run multiple kits at DDR4-1866MHz to get them to work and that is not an available setting. I suggest returning the memory and purchasing a single kit and not using multiple kits.
