I had 4GBx2 DDR4 G.Skill F-3000C15D-8GTZB on Asus z-170A with i5-6600k.

I bought 2 more sticks of the exact same product, but the PC fails to boot and keeps restarting before it even show the boot screen.
It starts when the sticks are only 2. Tried the memOK button but nothing.

Any insight?

You have about two choices here.

Move the two new ram sticks to the first two memory slots that should be used on your motherboard.
Place the ones that were originally in to the other two memory slots provided by the motherboard.

If you can get into the bios then raise as said the memory voltage by 0.250Mv.

If the board still does not boot with the change in order of the memory sticks.
Set the bios back to factory defaults by the jumper pins provided on the motherboard you have.

Power the system on, and enter the bios and reset it up with any manual changes you made such as the Sata port mode,
Ahci, Sata ect.
And the graphics card interface mode if using a Pci-e based graphics card in the system Pci-e mode.

All those people who say "just buy more it'll work if same type" do not know what they are talking about, that being said make sure the individual kits are in the same colored slot, bump dram voltage by .05v and if that doesn't work try loosening the first timing (cl) by 1

Thanks for your responses.

The each pair is on the same colored slots. With all the sticks on, I can't go to BIOS so I guess i have to bump the voltage when only 2 of them are on?!

I set the BIOS to defaults before the first install of the 2 new RAM sticks, and also removed the CMOS battery after some failed boots.


I ll try swapping the sticks on different slots.


BTW: In the mobo manual it has some charts with compatible models of O.C ram (above 2133) and in the 3000Mhz section shows my model. I attached a picture of it. Does this mean that only supports 8GB of the specific model and if I wanted more I should have bought one of the 16GB models?

So i just booted with 16GB of RAM. All I did is swapping places on the sticks.
I'm not sure if the swapping did the trick or the re installing them. Because this time i pushed them harder and noticed that at the bottom they went a bit further this time.

Not sure... Because before the PC booted with only the new sticks without touching them, so maybe it was the swapping :p

All is left now is to try to run them with XMP enabled.

(I guess even you have assembled a dozen of PC's there is a possibilty you missing something too obvious.)

Thanks again, both of you.

EDIT: It's all set. I just panicked a bit.
