DDR3 1600MHZ to DDR3 1333MHZ

I bought new pc but yesterday i saw the OS thinking the ram is 4GB DDR3 1600MHZ to 4GB DDR3 1333MHZ i have win7 32 bit and im going to buy 64bit (want more ram) in the box of the ram and on the chip write that is 4gb1600MHZ
win7 isnt support 1600mhz or the computer is worng?

More about ddr3 1600mhz ddr3 1333mhz
  1. Why don't u return it?

    And get a x64bit windows PC. Possible?
  2. Post the spec to the PC...
  3. first post: u talking about the ram?
    second post: GA-Z77M-D3H
    I7-3770K
    Seasonic 750W Active PFC 80MM 4*Sata 8-pin
    EVGA SuperClock
    WD 500GB Sata 3 Caviar Blue
    1 TB sata 2
  4. first post: u talking about the ram? The PC : )
  5. why ? its working but the os think its 1333 not 1600
  6. Well, the OS x64 will cost u $100.

    So return it and get the right one. If u can. And save.
  7. What is the RAM model?
  8. What RAM do u have now? Post the part #
    Use CPU-Z to find out @ http://www.cpuid.com/softwares/cpu-z.html
  9. I dont know why its on slot#4 and on the motherborad its ddr3_1

  10. 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.
  11. U have only one RAM stick?
  12. Its not possible to read your photo, but it says, it is a 667MHZ=1333MHz RAM stick.
  13. more 15 mins ill upload new pics of the stick
  14. 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.
  15. Where did u get it from?
  16. U have only one RAM stick?

    i remove the OC of the ram now its 1333
  18. did you try turn xmp profile on/enabled in bios?

    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
  20. it ussually under overclocking section. post your bios screen.
  21. Did u have changed the value of BCLK in overclocking section?
  22. What BIOS do u have now? The pic shows F5.

    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

    01 1.25 volt modules

    there is XMP setting,, try it enabled. it is under MIT\Advanced Memory Setting.

    there is XMP setting,, try it enabled. it is under MIT\Advanced Memory Setting.

    i dont have this thing on the bios! wtf?

    edit:i have updated the bios ill see now!
    edit2: after update 2 F8 no have this thing
  27. 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).

    i googled about the X.M.P thing and its for OC and im not going to do it right now
  29. 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.
