I have crucial 4gb ram with 1600mhz and i've noticed that when i go into bios i see that my ram is set to 1333Mhz. My motherboard supports up to 2200mhz and when i try to change it to 1600mhz i save changes and restart and the screen goes black and i need to restart it by myself and when restarts it shows me that what i did in bios is failed and i need to press f1 to get into bios and change it back to 1333 (auto) to get back to windows.
I searched online for help and found that i need to enable xmp profile, i don't know what it is, and i went back to bios and searcherd everywhere, but i couldn't find any xmp!

My specs
Asus h61m-c motherboard
Intel pentium g2030 @3.0Ghz
Gigabyte r7 250x o.c
crucial 4gb 1600Mhz ram
Corsair vs550 PSU

I could be wrong since it has been a long time since I messed with memory timings but from what I remember, first your memory bus has to be unlocked from the system bus. Most system bus speeds are a multiple of something like 133,150,166 depending on the motherboard. What multiplier is supported is also tied to the multiplier your CPU supports. Different CPU's user different speeds. From my experience just because your memory supports a higher speed does not necessarily mean it will "lock" or work with the motherboard/CPU combo you have.

My advise is to look for bus lock option to your memory in the bios.

Have you enabled the XMP profile in your BIOS? Shouldn't need to for 1600, but it's worth trying. If that doesn't work, you may need to increase the voltage slightly to you CPU's memory controller.

I would agree if we were talking about overclocking the CPU. As far as using an XMP profile, it doesn't matter whether you have a K chip or not. You can use XMP with any chip. The practical limitation is whether the mobo supports it and whether the CPU's memory controller can manage the speed. With the G2030, I wouldn't bother trying it with 2133 or higher, but 1600 is certainly do-able.
