I just did an upgrade from q6600 to the new i5 2500k sandy bridge using mother board gigabyte p67a-ud3p 5870 gpu 1500 watt pc power and cooling psu 1tb wd hd 8gbs 2 sticks times 4 gbs corsair vegnece 1600mhz 9 9 9 24 1.5... the problem i am having is that when i boot up my pc the bios show my ram at 1333mhz instead of 1600mhz so i go into mit and change it manually puttting in the spec for my ram. reboot my pc and then it lags for a while in the bios display screen.. then it loads up windows 7. while running windows 7 i notice theres also a lag there as well. i replace my ram and mobo still had same problem replace my cpu and still the sam problem. i ran memtest for 12 hrs no errors once o ever. now my concern is on the i5 2500k spec it states memory feq... 1333mhz im using mem at 1600 mhz is this my problem. also my mobo can support up to 2133mhz. then once in a while if i restart my pc i get an error on bios saying the system crashed due to an overclock. i need help guys can anyone help.. .when i had my q6600 and a x48 mobo running at 3.60 ghz 24/7 never had a problem... is there a bug in the bios or wat. also i have update my bios trying f3 f5 f6a and f6b still no difference... but if the ram is running on auto and runs at 1333mhz bios screen runs faster...
