RAM on GA-EP41T-UD3L

Hello..
I've the GA-EP41T-UD3L motherboard and the memory installed now is 2x2GB Kingston bus 1333.
My question is ( If I buy 1x4GB Kingston bus 1333 (or 2x2GB like the already installed ) and install it (them), 8GB RAM will work well or not? )
I've read on Gigabyte's site that the board supports up to 8GB.
And please what's the meaning of SD ( single-side ) or other types and how can I know the type of mine if they are SD or what ?
All I need to know ... what type, kit and everything about the RAM that I can buy to get total 8GB RAM?!
Here are snapshots from CPU-Z for my currently memory with all details..

Download and run Crucial's memory scanner: SDRAM, DDR2 and DDR RAM memory upgrades from Crucial.com

It will scan your system and suggest the best upgrade for your motherboard.

Your English is fine by the way. I only wish I could speak another language. :)

Thank you Seavixen32..
I'll download it and keep in touch :)

Scan by crucial is done...It says that the mobo max. memory is 4GB!! and the gigabyte site says it supports up to 8GB!
so ..

In that case you're probably best to upgrade with 2x2GB modules, which things leaves things matched in all four RAM sockets.
