Thx for all the help Guy.
Well I resolved the issue. What I did was update my the BIOS.(program called WinFlash). And it detected the the 4x by itself.
Well you were right it doesn't really make any performance diff.
But I am happy that I resolved it cuz I was on this issue for almost 4 months.
Thx again for your help.
