Question Why won't these stick work together?

[ganoo]

I originally had this set of ram here
https://www.newegg.com/Product/Product.aspx?Item=N82E16820231925&Tpk=N82E16820231925
which should be compatible with this set of ram here, even though its the newer RGB version

I am using this motherboard here https://www.newegg.com/Product/Product.aspx?Item=N82E16813157634&Tpk=N82E16813157634
Every time I boot up with both sets of ram in the motherboard, I get this image after the chance to boot into UEFI

When I take either of the set of sticks out, leaving one pair in, everything boots up like usual. Also, My pc actually seems to function fine after booting up past that attached image above, but eventually it will bring me to a windows repair screen after a day or 2, which forces me to remove one set of the sticks, and start over continuing the cycle. They're the same brand, same speed, same timings, same voltage requirements, only difference is one is a 16gb set and the other is an 8gb set. I always thought the issues arose from sets of ram with different timings and voltage requirements. Are there any solutions to get these sticks to function properly?

because mixing ram don't always works
oc the ram in bios

I have tried previously using an XMP profile setting both of them to their default 3000mhz clock, and then tried doing it manually instead of with the XMP profile. Would you recommend doing it to one ram set at a time? Does it matter if I use the XMP profile or just manually set it at 3000mhz?

manually.

manually.

With both sets of sticks in their or one set at a time? Sorry if that's a stupid question but I just want to be sure. Because before, I had both of them in their while they were overclocked manually, and the result was the same with the motherboard telling me windows failed to start 3 times etc.

Memory is guaranteed in the form sold. Other combinations you decide to make have no guarantee to be compatible together.

You might try manually setting the memory to a slower speed, relaxing the timings.

more voltage too
