Mixing SO-DIMM 2400Mhz with different CAS Latency

[davidst95]

I have a NUC 8 with one Crucial 16GB DDR4 2400Mhz stick with a CAS Latency of 17.    I would like to add another 16GB module.   Newegg has a G.Skill 16GB DDR 2400Mhz stick on sale with a CAS Latency of 16.   Is it ok to mix them together?   Would I have to manually set the latency in the BIOS?    Buying the exact same Crucial module would be an extra $20 or $30.   Thanks.

It'll work, but it won't be operating in dual-channel mode due to the different timings. However, not operating in dual-channel mode likely isn't going to cause any appreciable  performance loss.

I would buy the exact same module you have. In addition to what @Mira Yurizaki said, you'll also be limited to your slowest stick. In your case, the speeds are the same between both sticks. But typically someone has a 3000mhz stick and wants another 8gbs so they buy a 2400mhz on sale, they will then be limiting their 3000mhz stick to 2400mhz. I don't know for sure, but I don't think OCing them would work either as it'd be too unstable no matter what you do. You'll have to bite the bullet on this one.

it would work, but that second stick would clock to cl17 too

Thanks for all the quick replies.
