Help on buying RAM

[mrfi5]

Hi guys...I have a GA H55M-D2H motherboard.I currently have 4GB(2X2gb) of memory installed.Now I am planning to upgrade the ram from 4gb to 8gb(single stick-corsair vengeance).but some guys having this motherboard are having problems installing 8gb(single stick) of ram on a single slot(they say that they encounter a blue screen and the computer never starts).some forums say that,my motherboard supports 8gb of ram(2X4gb)but some say that it supports 16gb of ram(2X8gb).(I am really planning to install 8gb on a single slot which i am going to buy and another 2gb on another slot).
So the question is,
1.can i install 8gb(single stick) on one slot?
2.How much memory does my motherboard support?
I am stuck here guys.so pls help me out.

P.S:I have win 8.1(64 bit) installed in my computer.and sorry for my bad english.

1.can i install 8gb(single stick) on one slot? Yes ......but speed is decreased as it will run in single channel mode , 2 matching modules will run in dual channel mode = better performance
2.How much memory does my motherboard support? ..........16 gigs

Both other websites are incorrect, system memory I believe means total memory, therefore 2x4 sticks are the route to go. Take this motherboard as an example, it has 2 slots for RAM but only supports 8gb total: http://uk.pcpartpicker.com/part/gigabyte-motherboard-ga78lmts2p

So i can go for 8gb(single stick) of ram without any worries???I can install 8gb on one slot and 2gb on another slot,right???

It's an 1156 mobo and few to NONE support 8GB sticks, GB says it supports 8GB total (that would be in a 2x4GB config), and it shows the same in the mobos 1.4 version which I believe was the latest
