Adding additional memory

post #1 of 3
Thread Starter 
Hey All,

I am wanting to add an additional 8GB memory to my pc as an upgrade.

Current Build

Motherboard: ASUS P8Z77 -v
CPU: i5 3570k
Memory: 8GB (2x 4GB) corsair

I haven't listed all components as they are not relevant when selecting memory.

SO my questions are:

Can I use any memory?
Does the frequency need to be the same across all memory sticks?
Can I get 2x 8GB or 2x 4GB? will it matter?

I have never needed to mix and match memory before so I just need to k now what to watch out for.

All you have to do is make sure it's good quality memory with the same ratings for the speed, timings and voltage. Depending on what you find, it might be wiser to buy a 16 GB kit to replace what you have now.

I'm a bit more anal than most, but for me it's matched pairs or bust - for my personal rigs (especially gaming) anyway.
Same rated specs should be just fine as TC said, but an identical set to the one you have or simply replacing with a 2x8GB kit as recommended would be optimal.

Mixed pairs of RAM can be installed, but they will default to the lesser kit (lowest frequency/ highest timings) - how well they play nice with each other can really vary depending on what board you're using.
It would also need to default to whatever the highest required voltage is, so depending on the kits being used - it could pan out quite poorly.

Again, all why matched pairs/kits are always recommended if possible.
