Will increasing the MHz of the reference clock(HTT & PCI-E) optimize gaming performance?

the particular short resolution is yes, but it is a complicated progression for in all probability marginal dissimilarities.there are lots of points to consider.you require a table that helps such changes inside bios along with a clockable cpu.this is simply not for newcomers! have a peek at the varieties of things you will want to do:

as well, have a look at the AMD community forums too; there may be plenty of help available
(don’t take action! ):-)

it feels like your trying to find a better FPS (Frames For every Second) and also overall online game quality.while about clocking will increase it a few.it cannot make a lot difference.basically to add to you FPS and overall adventure quality you will need to change your own Ram and/or video card.

most laptops you are able to increase your Ram but is not your online video media card.

Desktops generally speaking both may be changed out there in 5-10 mins.check comparability in your current equipment before purchasing.
