What to look for in Memory Mixing

[J-Sharpie]

I have a question

After going through the forum for some time I take that as long as the DRAM type like DDR3 and DDR4, and Timing are matching there shouldn't be too much of a issue.

 

Speed will end up using the slowest of the mix. It will not be a average of the mix.

Brands can be different

Memory Size can be different.

 

So Hypothetically if I were to buy something like this: https://www.newegg.com/Product/Product.aspx?Item=N82E16820148982

• Ballistix
• 4GB Single stick
• DDR4 2400 (PC4 19200)
• Timing 16-16-16
• CAS Latency 16
• Voltage 1.2V

 

Then later decide to get something like this : https://www.newegg.com/Product/Product.aspx?Item=N82E16820233982

• Corsair
• 8GB Single stick
• DDR4 2400 (PC4 19200)
• Timing 16-16-16-39
• CAS Latency 16
• Voltage 1.2V

Now here's the question about the Timing

The former has 16-16-16 as a timing but the latter is using 16-16-16-39

 

Will something like this considered a match in timing or not?

There is more than just primary timings for memory, there is also sub timings which the motherboard defines, if I had to guess the DDR3 might even be faster as its more likely to have tighter sub timings. (motherboard dependant)

 

Good DDR4 is faster than good DDR3 though.

 

DDR4 3600 at CL 15 is a thing for example.

Thanks but my question still stands.
