Greetings,
I just upgraded my PC with geforce gtx 680 and an extra 4gb ram ddr3 mh1333
my mobo is gigbayte ep45t-ud3r
overclocked the CPU to 3.4 worked fine for 3dmark test and got a result on 7700 which is around 500 points without overclocking

but few minutes later my system crashed and now Im back to 2.83

my concern is the following readings why do I have these speeds and they should read for all 667 as the ram speed is 1333, what can I do to get the best performance with stability

and for some reason I cant update my mobo bios

Memory8,192 MB
Module 1 2,048 MB Corsair DDR3 @ 533 MHz
Module 2 2,048 MB TwinMOS DDR3 @ 667 MHz
Module 3 2,048 MB Corsair DDR3 @ 533 MHz
Module 4 2,048 MB TwinMOS DDR3 @ 667 MHz
