mixing ram Mixing RAM

[Luke_154]

Can someone help me out, I was wondering if I already have a kit of 2x8GB DDR4 3200 MHz ram. I'm getting another kit of the same ram at the same speed would XMP still work if it was a 2x16GB or does it have to be a 2x8GB kit. 

 

Thank you

I dunno about your BIOS but mine only lets me pick 1 XMP profile. Meaning that I expect it would work if the XMP profiles matched.

 

Saying that I have installed RAM with different timings before and never had a failure. I expect the sticks used the slowest settings of the 2 sets, but I don't know for sure.

 

Thinking about it I would have got matching MHz, just the cas etc settings would have been different.

Matching 2 sticks of RAM from different sets brings possible chance that it might not run at rated speed, but size of RAM doesn't have an impact, at least not to normal consumer. Fine to add together. All together for 48GB of RAM will be fine. But they all will run at lowest common denominator for speed and latency.
