Hi!

Just got a custom built computer. I have:
* Gigabyte G1.sniper z87 motherboard
* Intel Core i5-4670K
* Corsair Vengeance DDR3 1600MHz 8GB CL9 Memory

In BIOS i noticed that the memory runs in 1333 MHz. If i change the memory multiplier to 16 so that the memory runs in 1600 MHz the processor starts to run at 3.8 ghz constantly instead of variable clock speed. I don't want to overclock it to 3.8 before i get a better cooler. Should i just run the memory at 1333 MHz?
 
Solution
Your mobo (as do most all mobos) defaults to 1333, which any new DRAM you install will also default to, to set your DRAM to 1600, simply go into the BIOS find and enable XMP and select Profile 1

here is what i think

your mobo supports 1600 by default, no oc required

your ram seems 1.5 v, again it should be recognized without any bios tweaking

you should not have to do anything explicitly to get it running at 1600

edit: on a second thought, have your upgraded your bios version to F2?

Will i get any noticable effects from running XMP and setting the ram to 1600 MHz?

Now when i turned on XMP the board changed the memory multiplier to 16 and then the system started running at around 3,8 ghz all the time instead of variable between 800 mhz to 3,8 ghz. Can't i run the memory at 1600 mhz without affecting the whole system?

Hello everyone.
I am having the exact same problem. I just upgraded my pc and i bought the Asus Maximus Extreme Ranger which by default uses 1333MHz and 1600MHz speeds without overclocking. I installed 2 x Corsair Vengeance (4gb each @ 1600MHz) which should run at 1600 without enabling the XMP profile.

However this is not the case. In order to get 1600MHz i have to enable XMP.

I saw the reply which says the problem was Samsung SSD-tools. Can you help me with this? Is this setting in the bios or in windows?

Does it have anything to do with the fact that i have a Samsung 840 EVO?

If yes, what does this have to do with ram?

Thanks.
