most mb read the jdec info and look for a standard speed. 1066 or 533 is a standard ram speed. in the bios there should be under dram speed a setting called xmp profile. you have to use that to get to 1600 speed.

Its wrong RAM. U need 1.5V. Not 1.65V, as the IMC on the chip doesn't like the voltage above 1.5V.

It may kill your CPU, happened before.

Maybe that is the problem. But it still should show the 1600MHz mode.

what do u mean? i have the new bios and i dont know how to use it lol
i forgot how i did it but i change it from 13.33 to 16.00 but after 5 mins i changed it back to nurmal becuz i saw the cpu getting to 4.00 ghz without touching the cpu overclock and temp was 50c

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 sets the XMP profile. I agree, Intel's JDEC specifications stipulate 1.5 volts .... for JDEC profiles ..... but XMP "allows compatible DDR3 memory to perform beyond standard specifications" and is "predefined and tested" by Intel

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.

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 ? For JDEC profiles, I agree, for XMP profiles, again no.....most listed compatible i5 / i7 RAM is 1.65 .... at least according to Intel's compatibility lists

from what i know, gigabytes ovrclocking/advanced features are hidden from standard menu, it needs to hit some key to reveal all the features. ussually that key is Ctrl+F1. This bios has two modes, 3D mode for casual, and advanced mode for overclocker. You need to find how to enter the advanced mode. From my previuos screenshoot, there was a hint,, F1 key is 3D mode. Then maybe F1 could also be applied to enter advanced mode.. try it, then see if you have that menu (XMP).

OK that's fine if you dont want to do it. Just for your info, your ram basically supported XMP, the only way to achieve 1600 with this RAM is through overclocking it (it just overcloks your RAM), and since this XMP is a profile made by the manufacturer, then it should guaranted tobe working and safe (but not always compatible with your m/b). But if you dont want to use XMP, maybe you want to get other RAM but with 1.5V,, 1.65V basically always an XMP thing.
