Dual Channel Kit or Quad Channel Kit?

[On_Point]

Hi guys, I am looking to add some more ram to my system. Right now I have 8GB (2x4GB)
If I want to add another 8GB, is it ok to just buy another dual channel kit or should I buy the whole 16GB as a quad channel kit?
Will using 2 dual channel kits in a quad channel setup cause problems?
This is what I have now: http://www.amazon.co.uk/gp/product/B008YAI7E4?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

It SHOULDN'T if you get the same exact 2x? kit you have.

Just buy another of the same kit and you should be fine.

Ok thanks guys. Can either of you tell me if these are the same?
The one I bought last time is this http://www.amazon.co.uk/gp/product/B008YAI7E4?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00
But I found this which seems to be the same but cheaper http://www.amazon.co.uk/dp/B00M7S83I4/ref=gno_cart_title_1?_encoding=UTF8&psc=1&smid=A3P5ROKL5A1OLE

Do the item model numbers match?

The model numbers seem to be slightly different
According to Amazon one I bought is KHX18C9T2K2/8X
The cheaper one is HX318C9T2K2/8

Don't suppose they accidently missed out the K at the start and the X at the end? lol

EDIT:
The cheaper one is the newer version according to Amazon...

I would get the one that matches the kit you already have. Mismatching memory can cause weird, unforeseeable issues that can be avoided this way.

However, if you aren't running an X79 system, you won't really be running quad channel (instead, you'll be running two dual channel), so you might be able to get away with the cheaper kit IF your motherboard supports separate timings for both pairs of memory, and you make sure to install each kit in matching channels.

Still, the safer bet is to get the matching kit.

You have quad channel platform so look for 2x4GB predator - should be still the same or almost the same as all were on new Hynix CFR/MFR. You can also sell your 2x4GB kit and look for 4x4GB as there is no guarantee that Kingston is using the same memory chips in new kits.

Thanks guys, I think I will go for the 4x4GB of the new version and sell my 2x4GB. The price difference between getting another 2x4GB of the old version and 4x4GB of the new one is not that much. But I wonder why the new version cost less...I hope the performance is the same if not better.

So long as the speed and timings are the same, there wouldn't be a performance difference.
