In the i5-2500k's specs, it says it supports 1066 and 1333 mhz ram, but I see a lot of people use the 1600 mhz rams, does that cause system instability or anything? does it really make a difference in performance to own the 1600 ram compared to 1333?
(right now I'm using an i5-760 with corsair dominator 1600 mhz 1.65v ram and my computer does freeze randomly about once or twice a day so i'm wondering if getting an i5-2500k and 1333 ram and new mobo might fix the problem. it might also be the video card though who knows.)
Faster DDR3 RAM makes hardly any system performance difference. You can run Memtest86+ from a floppy, CD or flash drive to check the RAM. Trying to run RAM faster than 1333 Mhz. could cause instability.
So if you buy 1600 1.5v MHz ram, such as the vengeance, you have to overclock the i5-2500k for the system to be 100% stable? Or are you saying that you can underclock the 1600 mhz ram to 1333 mhz and not overclock the cpu and it will be stable?
