Hey,

I need some help with the following.

In 2019 I bought a computer and put the following rams.

HyperX HX426C16FBK2/32
2x 16 GB

Today I wanted to add an additional 32GB, so I purchased the following.
HyperX Fury HX426C16FB3/16
2x 16 GB

When all four rams are put in, screen doesn't respond.
As soon as I take out the two new ones, the computer turns on.

Rams should be compatible with each other, as its both DDR4 2666MHz?

or am I wrong?
What can I do?

What CPU and Chipset are you using

i7-9700K CPU
Z390 AORUS PRO-CF

voltages and timings the same?

are you using xmp?

I have no idea, how do I check this?

in bios

go into without the new sticks

or try to clear the bios with new sticks in too

do I enable XMP to profile 1 or disable?

and how do I fix timings?

turn it off to check

but id try to clear/reset/default it first

so I just tried going in to bios, I honestly dont know what I'm looking for.

Pulled out old ram, tried only with the two new and that didnt even work.

Can you tell me what I'm looking for in BIOS?

I tried activating XMP Profile 1, didnt help.

How do I fix timings? Or how do I turn off timings?
