Different memory than motherboard support list?

Here is the list of 'supported' memory for my motherboard:
http://www.asrock.com/mb/Intel/Z77%20Pro3/?cat=Memory

Here is a search for memory within my price range (the first page):
http://www.newegg.ca/Product/ProductList.aspx?Submit=EN...

None of the model numbers match up, do they have to be the exact model number, or just the same pins, channels, speed and size?

Any RAM from any manufacturer should work regardless of whether it shows up on the mobo manufacturer's compatibility list. Just make sure the speed matches what your board can handle and you're good to go.

Of those sticks, would pick one of the Trident sets, that's what I run on my Z77 (in sig), make sure you have a K model CPU 2600K, 3570K or 3770K), not likely to be able to run at full 2400 without a K model

@ Tradesman1 - I don't have a K model CPU, but I managed to easily OC 3.6 from 3.0 using the AsRock board. So I am curious how it will work, I don't see the point in buying slower memory, as its only like 50 bux cheaper.

Anyway, I am having a hard time understanding Dual-Channel memory.
What I am confused about is the memory I want to buy is 16GB (2x8) Dual Channel... what if I want to upgrade in the future and get two more sticks, does this mean my 4 memory slots will be divided into two separate operations basically? if not, can someone please explain? (or am I completely off, and need to buy single channel if i want to upgrade, because I want to use all 4 of my memory slots?)

You currently have 2 channel (basically A and B) - A is the 2 slots closest to the CPU and B channel the two furthest away - so normal config in sticks in slots 1-3 or 2-4 so you have 1 stick in each channel....the MC (memory controller) then sees both sticks (or all 4 in the event you have fully populated the slots) as 1 single 128bit device (each DRAM stick is a single 64bit device) and from that you can gain a performance increase of appr up to 10-15% vs single channel mode....If you were to run say 3 sticks - it would run in what's called Flex mode - the mobo would see 8GB in each channel and run it in dual channel mode and see the 3 rd stick as an odd 8GB and would run it as single channel alongside the other 16GB that are in dual channel -best to go 2 or 4 sticks and have all in dual channel mode for best performance ;)  And with your OC, go for it, and try the faster sticks, can downclock if need be and with tighter timings still get near same performance
