Hi sifus, i'm a newbie in this and not sure if this consider as overclocking or not.

I got BSOD during map switching when playing Battlefield 3.

On Bios settings i changed ram frequency from 1332mhz to 1648mhz (btw bios only shows 1648mhz and not 1600mhz exactly)
if i set back to 1332Mhz i wont get any BSOD.
problem is my ram is suppose to support up to 1600mhz....


Running on Windows 7 64bit

Here's my spec
Intel i7 2600K 4.4ghz(tuned with Asus optimal mode.)
Asus P8P67
Cosair vengeance 2x4GB DDR3 1600 C9
Sapphire ATI Radeon HD5850
WD 7200 1TB x2
Cosair GS600




Please advise dear sifus. thanks!
