My old motherboard pciE slot gave up on me. So i decided to upgrade my processor and downgrade my mobo since there were not allot of options for lga1155 chipsets at my side. So i ended up buying a core i5 3570k with an Asus H61M-k motherboard. I went for this motherboard since it was good for the price, has good warranty like 3 years (others only had an year) and found out that it had memory overclocking support up to 2200mhz. So i went for it. I finally bought 2 4gb sticks of 1866mhz hyper X kingston memory. But when i went to the bios and tried to overclock. Every time i would set the clock frequency and reset my screen would be blank and then i would turn off and on again it tell me OC failed. Its not even running on 1866mhz but its set to 1600mhz. I also changed the time speeds and upgraded my bios to the latest but still its not overclocking. Can anyone help me. Also i am a some what new to overclocking though i have studied about it. So yeah waiting for help.
