Is it worth sticking one die of 8 GB with the remaining 4 GB?

Question

Iron

On the computer there were 1 8 GB dice and 2 of 2, that is, a total of 12.
In the process of upgrading another computer, 4 4 GB dice were released.
At first I just wanted to put them instead of 12, 4x4.
But then the thought came - if you leave 8 GB - it will be more.
Hence the question: what is better for performance - to put 4 identical 4 GB sticks or stick one non-standard 8 to them?

Answer 1

Put 8 + 4 + 4 + 4, if the dual-channel mode works, then leave it like that. If it doesn't work, then ... leave it too, if you don't know if you need a two-channel mode or not. Well, if you know exactly what you need, put 4 * 4.
ps Several times I tried to set 8 + 4 - the dual-channel mode always worked, though I set it mainly for the test, there are paired modules of the same volume in the workers.

Answer 2

In numbers (that is, in tests, not real applications), 4 by 4 will be faster, more precisely, two pairs of four - dual-channel mode and all that. But there are only a few percent difference. Maybe in your configuration it will be more important to have 20 gigabytes instead of 16, or maybe vice versa, 16 but 4% faster :).

Answer 3

Depends on your tasks.
ps 4 of your identical dice is not a fact that they will work in Dual Channel. Better check it in bios.

Answer 4

it is better to use more memory, but with a limit on the slowest
one, than to increase the speed by losing in the total amount
(double channel, putting two 2GB 1800s, than three 2GB 1333 dice
