[rajat501]

and
asus sabertooth z97 mark 2 so i set XMP profile in bios so is this done or i have to increase DRAM voltage or anything

and this is safe or this will void my warranty

thnxs for help

You should be all set, and no it will not void your warranty for either the DRAM or the mobo. You should only have to increase the voltage if it won't run at it's rated speed with XMP enabled.

Update: If you download and run CPUID, you'll be able to verify that it's running at the speed it's supposed to. Just remember to multiply by 2 whatever speed is listed (i.e. 800MHz means that the actual speed for DRAM is 1600MHz).

If you set the profile to XMP, then you should be able to see the speed and timing right there in the BIOS. As to warranty, peeps have been yelling the sky is falling, claiming that you void the warranty at anything above 1.5 volts. False.

Here's an old post of mine from back in 2012

At 1866 I doubt you will need to increase voltage .... I usually don't have to up voltage for 2133 and below and even at 2400, only when I have a good overclock....(say 4.5 and up)

===============================================

1.5 volts is for the JDEC profiles .... most XMP profiles for i5 and i7 RAM is 1.65. In fact, over 2/3 of the RAM on Intel's XMP compatible list are over 1.50 volts.

I have seen many posts saying "Well that's a MoBo manufacturer thing". No....

Intel® Extreme Memory Profile (Intel® XMP) allows you to overclock compatible DDR3 memory to perform beyond standard specifications. It’s designed to enhance the gaming features built into Intel® technology–based PCs. If you like to overclock and squeeze as much performance from your PC as possible, then memory based on Intel XMP gives you that extra edge you need to dominate—without breaking a sweat.1

Predefined and tested Intel XMP profiles can be loaded via BIOS or a specific tuning application through a computer’s operating system. Often the easiest way to load Intel XMP profiles is using a tuning utility, which may be available depending on the particular board manufacturer. To learn whether a tuning utility is available on your system, you should contact the board manufacturer.

So ya still say Intel says 1.5 ? Again, no.....most listed compatible i5 / i7 RAM is 1.65 .... at least according to Intel's compatibility lists

Intel's approved i7 Compatibilty List (April 2012) includes:

34 1.65 volt modules
07 1.60 volt modules
19 1.50 volt modules
01 1.25 volt modules
