My first time here so hi to you all 

I am from turkiye  so  english isnt my first language, sorry about mistakes.
I have this mobo and these  ocz memories  x 2 kit.
Before I go any futher my system;
X58A-UD3R
i7 960  3.2 ghz (No OC)
OCZ 6GB 1600 MHZ x 2
Msi  6870 hawk X 2 Crossfire
1x westerndigital 1 TB sata3 black claive  on sata 3 port (windows 7 ultimate)
1x seagate  1 TB  sata 2   on sata 2 port
1x creative titanium HD 
1x Highpower  750W  psu
I built new system after 2 years.
When I first build my system I was have 1 kit rams. these rams supoosed to run at 1600mhz  8-8-8-24  1.65v  and  these rams in mobo's memorie suppot list . I am getting random bluescreens   with codes    '3B'  or  '50'   and some more cant remember well.  even getting bluescreens with default setting  which is eveything on auto. ex: rams = 1066 mhz...    Not getting always but lets say 1 time every day  or in 2 days..  sometimes I run computer for 10 hours  nothing come out ... I shut down, go out for work and  come back push button,  just before windows screen again  blue screen.. its really annoying :/ I run 10 hours memtest  nothing came out also tryed single by single tests  no error.    then I bought 2. kit ram  again ocz brand same kit. I didnt use old ones at first. and  tryed new ones  but again bluescreen with differnt settings. default / 8-8-8-24 / 9-9-9-24 or 30   1.65V  auto volt... Maybe I have another problem on mobo  not sure which part I am failing. sometimes post screen takes 20-25+ sec... 
 I went ocz forum  post there. I didnt get any answer sadly  >>

Anyways thank you for reading. I am not hoping to get any answer you will tell  ask ocz most probably. they are not caring  either  bcuz I called gigabyte in turkiye. they told me  this mobo isnt suppot 1600 mhz ram so your fault.  I dont know if its my fault  since these rams  in memorie list for this mobo..... And still I am not sure if this memorie problem. Just letting you know  an unhappy custemmer here
