http://www.gigabyte.com/products/product-page.aspx?pid=3519#ovThe PDF file (QVL) include the following list and only one G Skill module (G skill Flare which I have not been able to find anywhere) is recommended to achieve pure 2000 Mhz (the speed the motherboard is capable of) and also includes other speeds:
DDR3 2200 (downgrade to DDR3 1866)
DDR3 2133 (downgrade to DDR3 1866)
DDR3 2000 (gskill Flare)
DDR3 2000 (downgrade to DDR3 1866)
DDR3 1866 (kingston KHX1866C9D3T1k3)
DDR3 1800 (Geil)
DDR3 1600 (several brands: A-DATA, Corsair...)
And the longer list is the one that follows and are DDR3 1300 Mhz.
So if I have understood well even the Qualified Vendors List for the Gigabyte 890FXA -UD5 (the ones above 1333 Mhz) are a real danger itself for the memory controller too?
Do you think I will have less possibilities of that to happen (broke the memory controller) having a Phenom ii X6 1055T CPU with E0 step version ?
If both answers are Yes then I guess will be safer and consequently more cheaper to get a 1333 pure module and be happy with it... Cause in fact the difference of speed between 1333 Mhz to 2000 Mhz is really that significant ?
And also....will you buy a GA-890FXA-UD5 second hand knowing that during almost a year or more memories have beeen running above 1333 Mhz ? I guess maybe is why the seller wants to sell this motherboard....he has been running memories above 1333 mhz then consequently has found errors while running windows, games, etc...but maybe that board if I buy it now will be a bomb clock about to explode on me if I try to overclock it above 1333 Mhz. What do you think?
Thanks a lot for you patience and amazing support.
