Overclocking Kingston HyperX RAM to 1600MHz

post #1 of 6
Thread Starter 
Hello everyone, I've been trying to overclock my RAM by changing the Memory speed slider from 1333 to 1600 in my BIOS. That's the only thing I'm changing. However, every time I reboot and check CPUZ, it shows the RAM running at 666.7 (666.7*2=1333). Can anyone help me out here? I'm not sure if I need to change the CPU BCLK or other settings. Thank you!

Use the XMP settings. The voltage and timings probably have to change. It will set them for you

Ok, I found the XMP option in the BIOS but it is greyed out. How would I go about turning it on?

I am not sure but since you can manually change the ram speed leads me to believe that is why xmp is greyed out.

I am not familiar with your bios but I am pretty sure a cmos reset would restore the ability to set xmp.

Probably a less drastic change would also achieve this like an auto setting for memory or something like that.

Now I realize this probably isn't a big help because I am sure you don't want to reset but I just wanted to give you an idea as to why it is greyed out.

Thanks for the replies. I was trying to change some things to manual to get the xmp to work, but never could. I changed everything back to how it was and left the memory multiplier at 16.00. I rebooted to type this and checked CPUZ, lo and behold it now says 799.9MHz. So it looks like it worked somehow. One other question though. The motherboard can support up to 2333MHz RAM but the page at Intel for my CPU says it only supports 1600MHz. If I tried to go any higher than the 1600MHz now, would that damage the CPU? Or would it just not work? The RAM is manufactured at 1600MHz by the way, so it isn't overclocked now.

Anything above 1600 is not guaranteed by intel. You may be able to adjust stuff to get higher speed ram to work but it's not 100% guaranteed to work. It's likely it may go a bit higher
