mixing cl9 memory with cl10

[Jimbojim]

Hi, I went to buy some more memory today and at the store I didn't remember exactly which one I had bought when I initially built my pc 3 years ago so I asked them to look into their archives and tell me which ram modules I bought because I wanted 2 other sticks of the same.

 

He told me I bought Kingston HyperX CL9 but they don't have any of those in stock so he sold me some Kingston HyperX Fury CL10 saying that they will calibrate themselves to the same speed.

 

I still bought it because I can still return it, but is it true? Will I have to change some settings in the bios or are they completely incompatible and he was just trying to make a quick commission?

It should just run at slower speeds on it's own.

Lol he sold you it knowing they were different timings

 

It probably will work though tbh, the best case scenario would be that they both run fine however they will run at the slower speed CL10 not CL9, which isn't the end of the world. 

 

The worst case would be that they are unstable and will cause you issues down the road or right away. If you want to avoid any trouble I would just return it and look somewhere else for the exact same one. 

 

(But some people do get away with using ram of different latency's/timings)

Just like he said:they will calibrate themselves to the same speed.

They will work anyway, they will run, including your old sticks, at cl10, you'll have to find out if the new ones are able to run stable at cl9.
