Hi, just wondering if anyone knows on what exactly would I have to do to make my current, single stick HyperX Fury 8GB in 2133MHz be able to dual channel with a HyperX Fury 8GB in 2400MHz - the 2400MHz stick is arriving today, and they are the same RAM module except different speeds (as far as I can tell). Cheers in advance

Edit:

Kingston HyperX Fury Black 8GB DDR4-2133 PC4-17000 CL14 : 14-14-14 1.2 V


Kingston HyperX Fury 8GB DDR4-2400 PC4-19200 : 15-15-15 1.2 V

There's a difference in CAS Latency by 1, but there's another thread where the user manually set some values to Dual Channel or something like that.

At stock, it will be dual channel but both sticks will run at the speed of the slowest stick (so 2133 Mhz in this case). If you manually set the speed in your BIOS to 2400 MHz they'll both run at this speed, technically you'll be overclocking the 2133 stick but from my experience nearly every 2133 MHz stick should be able to run at 2400 MHz easily with no tweaks to latency, voltage, etc. Hope this helps! :)

What about the 1 CAS latency difference? Should I tweak that anyhow?

They will need to be equal yes, if the 2133 is 1 lower as i imagine it is, simply raise it by 1 to match the 2400 stick or you could try run it at the latency of the 2133 kit even at 2400, this is better for performance but may cause instability as overclocking can also.

I've got a B250M PRO-VD mobo so I'll raise my 2133 latency to 15 to match the 2400 and let them dual channel at 2133 since I don't think I can overclock on a B250M, cheers for the help.

From my knowledge you can overclock RAM on B250 Motherboards without XMP, but only up to 2400 MHz which is what you're aiming for.

Alright, yeah I can - I just upped the rate to 2400 and changed the latency and it's fine, I'll check the other module's rates and just copy them on my 2133 stick just to be safe though - cheers for the help.
