I need help selecting more memory to add.

I have a desktop PC with a ASUS P8Z77-V PRO LGA 1155 motherboard. It already has this in two of four memory slots: Corsair Vengeance Blue 8GB (2X4GB) PC3-12800 1600mHz DDR3 240-Pin SDRAM Dual Channel Memory CMZ8GX3M2A1600C9B. Can I add 2 8GB memory modules and keep those in? Or do I have to use either 2 or 4 8GB modules? Which should I get of these two products to combine with the 4GB memory already installed if I can combine them?

Corsair Vengeance Black 16GB (2x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMZ16GX3M2A1600C10)
http://www.amazon.com/Corsair-Vengeance-Desktop-Memory-...

Corsair Vengeance Blue 16GB (2x8 GB) DDR3 1600MHz (PC3 12800) Desktop Memory CMZ16GX3M2A1600C10B
http://www.amazon.com/Corsair-Vengeance-1600MHz-Desktop...

Most people are buying the black one. Should it matter to me which one I get? Can the black 8GB modules be put in there with the blue 4GB modules?

If I cannot combine 2 modules of one of these products with my 2 modules of 4GB memory, then which should I get to install 4 8GB modules? Is one better than the other or something?

Thanks.

you do not need to add 2 other memory stick because you do not have quad channel supported on your mobo
better to stay with 2 memory stick kit in dual channel mode

Thank you for the post. I appreciate it. Sorry if this seems tedious, but I do not understand PCs very well.

This motherboard has four DIMM slots. They must be there for some reason. Is it not two DIMMs per channel with this thing? What are you saying, that my CPU does not support the use of all four DIMM slots? That does not sound right. Various sources of information seem to be saying this motherboard allows you to use 2 DIMMs per channel, so why is it that I need quad channel support to use all four DIMM slots? I really need as much memory as I can get this system to use.

Your mobo can run up to 32GB in Dual channel, ignore BadBoyRog2 as he has no idea what he is talking about. The mobo is strictly dual channel (2 slots allocated to each channel - norm is Channel A has slots A1 and A2 and Channel B (same) B1 and B2 - Quad channel is only on X79 mobos (socket 2011), Your best bet is to buy a single package of the full amount of DRAM you want, mixing sets of DRAM (even of the same exact model can be and often is problematic.

''ignore BadBoyRog2 as he has no idea what he is talking about.''

ARE YOU A MODERATOR????????????
i know a lot of things about computer , i built pc since 20 years , and i am sure i can teach you a lot of things too , so take care of how you speak in this forum please , respect..respect
so i think is time for retirement man (tradsman1)
you should apologize to me ...i can not believe it

anyway of course he can add two more ram up to 32 gb ...but it should be the exact ram like he own now for compatibility , but i suggest him to by 2 X 16GB DDR3 dual channel kit ,dual channel mode give 20 to 25% more general performance ; if he had a quad channel memory ...better with 4X 8GB DDR3 ram stick kit

@Tradesman1, thank you for the info and the warning about getting it all in one kit.

@badboyrog2, I think DDR3 DIMMs only go up to 8GB, man. Thanks again for the replies.

So you are suggesting getting 2x16GB, because you know 'lots' about computers, hmmm, like maybe basically all 16GB DIMMs are all ECC sticks and the mobo here doesn't work with ECC sticks....or how about the mobo won't even work with 16GB sticks? it supports up to 32GB in a 4x8GB config.....how about dual channel mode at most can provide up to a 10-15% performance increase, and normally not even that, which is nowhere near the 20-25% you claim. Or this is obviously a a dual channel mobo so why even mention quad channel and this mobo - it's not happening. Then you say 'add 2 more RAM', when it's never a good idea to mix sticks, even of the same exact model, it can be and often is problematic, the forums here and all over are filled with people who have taken this type of ill advised advice and ended up with stick that won't work with the old ones and costing them money from returns, RMAs, restockng fees, etc. Simply based on your responses it appears you know very little about DRAM...

Retirement ;)  I think not, I have my own systems business and will prob work as long as I can, as well as helping out on the forums...Respect is something one earns, and in the forums that's from giving good, knowledgeable advice and help, it's not earned by just spouting off incorrect things and then making demands for it.

well tradsman ...know a lot of things its a thing ..but when you say that ''ignore BadBoyRog2 as he has no idea what he is talking about.'' thats an other story...there you need to learn something , you do not think?
your are not alone here , and everybody need respect and everybody have the right to do mistake and post , if you check my profile you will see all the best answers i had and that only in somes months

and 16 gb ddr3 no-ecc stick exist at intelligent memory company , but its rare and expensive and i do not know if his mobo can handle that? i do not think so and i do not know why is so hard to find?
but with the new ddr4 memory you will see this kind of memory , but i am agree actually 16 gb no-ecc is hard to find
i am just curious why ''camerad'' need as much memory?
so in the futur i will just ignore you tradsman about your insults and your god complex

As I said respect is earned, what if Camerad had gone out and bought 16GB sticks, based on your "know a lot of things" advice, to the tune of of $600 +, only to find it wouldn't even work - would you have given him a refund? No, it would have to be RMAed (shipping charges, prob restocking fees, and all for what? Nothing! As far as 'needing' so much memory - again, that's not unusual at all. Yes you'll see 16GB sticks with DDR4, in large part that exact reason, many people do need lots of DRAM (keep in mind DDR4 isn't going to work in DDR3 mobos, nor with DDR3 based MCs in current CPUs unless the mobo makers add a chipset to handle DDR4, so bringing up DDR4 for this thread is a moot point). Basically it comes around to your knowledge in saying to stick with two sticks instead of four as his mobo doesn't support quad channel, which simply doesn't make any sense, as 'quad' channel isn't even a factor here in any sense.
