memory - Corsair & G.Skill DDR4 Ram compatibility

My configuration:
Processor: G4560
Motherboard: MSI B250M PRO-VH

Can I use these two rams in dual channel ?

Corsair DDR4 2400 8GB

G.Skill DDR 2400 4GB

I know that both of them need same speed, timing & voltage to use in dual channel mode. I couldn't find any timing in their specs & their latencies are different . Will different latency cause a problem?

I have DIMM A1 & DIMM B1 slots in motherboard. Where should I put which ram for better performance ??

Thanks

Answer

The "latency" parameter you see in their specifications are the timings (if they are 4 numbers like 1-2-3-4).

Different timings will cause a problem and latency is one parameter of the RAM timings.
Insert the RAM sticks into two different channels (one into channel A, and the other one into channel B), since they can't work together in dual-channel, however, this won't really make a difference for performance in your case.

Explaining timings:
Timings are usually written down in the a-b-c-d (CL-tRCD-tRP-tRAS) format.
The abbreviations for those timings are as follows:

CL: CAS Latency. The time it takes between a command having been sent to the memory and when it begins to reply to it. It is the
time it takes between the processor asking for some data from the

memory and then returning it.
tRCD: RAS to CAS Delay. The time it takes between the activation of the line (RAS) and the column (CAS) where the data
are stored in the matrix.
tRP: RAS Precharge. The time it takes between disabling the access to a line of data and the beginning of the access to another
line of data.
tRAS: Active to Precharge Delay. How long the memory has to wait until the next access to the memory can be initiated.
