Question regarding Dual Channel Memory- Mix or Match Memory

I have a computer I built and used since 2010 running well. It has two matched 4GB sticks of DDR3 for a total of 8GB. I have two remaining slots (empty) for ram on the motherboard to add more ram. Do I need to find the exact same memory as the ram I am currently using or does it matter?

If you can get the same kit again it would be best but if you can get a kit with the same timings, speed, and voltage you should be okay. You should use cpu-z to find out your kit model and timings it supports. CPU-Z | Softwares | CPUID At the moment your two current sticks should in the white slots.

I am new to CPUID. Here is what it says about my existing memory. So far I cannot find anything on the internet with the same Kingston part number. What specific items do I need to match?

Hi,

I updated my system specs and here is the HWiNFO.



I could not snag to the bottom of the screen. Here the the complete right panel.


Could you please point out the significant specs I need to know when selecting matching memory to what I am currently using?

You want a kit that has these specs. So a ddr3 1600 8GB kit (2x4GB) with main timings of 9-9-9-27 like it shows in cpu-z and in HW info's summary page since your xmp is what you would pair too. Mine is like this, see how my xmp is highlighted.

EDIT: Added a screen of what tab in cpu-z will show you what your ram is currently set at in the bios, your's should be 800mhz on that screen cause 800x2 is 1600mhz in dual.

i'd open the computer, take out one stick, google whats on the label.
model name starts with letters like kvr, hx something.
if you cant get the exact model, follow rvcjew's advice.
