If 2 straps: one 8GB, 4GB second
Let's start with this.
So. It is necessary to consider such factors as:
Clock working clean RAM in MHz.
Operating clean in MHz. (if a single module works on, for example 1333MHz. And the other at 1600MHz, the work of both modules will be at 1333. Everything will fall into less).
how will this affect the work and memory performance?
But the effect is very simple. Press the start button computer. If start then praise something higher and it works. If something goes wrong, the computer does not startanet, or will not, put one of the modules.
I have everything ;)
Thank you for your attention, good.
So everything is beautifully painted, don't want to remove ;)
Launched comments and saw links to products.
Based on the information released. Both modules will work on cleanliness "2400 MHz" as I wrote above.
