G skill ripjaw x showing as 1333 mhz on windows7 what is the reason

[digitalanand]

Hello Techies,

I purchased intel DH77EB & i5 3470 and G Skill Ripjaws X (F3-12800CL10S-8GBXL), by default board got detected as 1333MHz clock speed for RAM and i have overcloed it by manul settings to 1600 MHz, But upon booting my Windows 7 OS showing as 1333MHz still, what would be the reason. Please hlep me to use my RAM's *8x2GB) at 1600MHz clock speed.

Thanks you in Advacne !!!.

Where is memory speed listed in windows 7?

I assume the RAM is installed in the Blue DIMM slots, and next boot into the BIOS and enable XMP and use Profile 1. The Ivy Bridge can use >DDR3-1333 on the H77, and apparently your G.SKILL lacks an 800MHz JEDEC 'SPD' but has 'XMP-1600' only which is more the norm so it will default to DDR3-1333 (667MHz).

Can you tell me where the memory speed is listed in windows 7, I would very much like to know.

I know you can test the RAM and see the GB's breakdown, but off the top of my head 'frequency' I don't there's a 'built-in' application. Even if there were I've always used CPU-z, AIDA64 Extreme and Memtest.

I do know very view kits have both a 'SPD' and 'XMP' up to the kit's rated frequency/CAS.

Here's an example, using CPU-z, of a 'typical' DDR3-1600 kit (less the low voltage) note the 'SPD' is for DDR3-1333 and lacks JEDEC 800MHz for (DDR3-1600) therefore by default (plug-n-play) it'll run DDR3-1333 on a SB-E or Ivy Bridge CPU. A few kits do have JEDEC 800MHz (SPD) so the Plug-n-Play will run DDR3-1600. XMP-1600 is not a JEDEC, therefore not a plug-n-play for default.

Ya, I did not think so, that is why I questioned the op on where he found the frequency listing in windows. I guess not all people read the manual when installing componnts.

 

[jaquith]

Chances are the OP assumed or used an app to determine frequency, and maybe there's a way that I'm not aware of or pre-installed apps on the OP's PC. I'd still have to actually see the CPU-z for the OP's F3-12800CL10S-8GBXL sticks.

Otherwise I know you can run CMD.exe and WINSTAT MEM but that only gives you 'MB/s' but that's more about the CPU + RAM.

Friends,

How can i add image while replying, as i am new to this forum, please help me.

Thanks

Hello Friends,

The above link is for cpu-z verion 1.59, so it's didn't picked up the RAM settings.

I have installed 1.61 version and now it's show ing RAM settings. Please find the below link and let me know your inputs, i was checking RAM clock speed on Intel Desktop Utility Tool and it's showing as 1333mhz, but now CPU-Z showing correct i guess, please suggest me on this.

Thanks

Perfectly fine.

CPU-Z says 800mhz, that's correct.

Not that 1333mhz and 1600mhz make a difference.

 

[digitalanand]

Thank you Amuffin,

But, why the Intel Desktop Utility showing as 1333Mhz, could you please explain me.

Thanks

Like any polling utility, as you've discovered with CPU-z, if it's older might produce erroneous information. Try Intel's latest version found here (3.2.4.055b ; DH77EB support is listed) - http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-boards-software-desktop-utilities.html

Thank you Jaquith, will try to install latest version of Intel Desktop Utility and will update you soon, Thank for your suggestions and valuable time.

Cheers !!!

I trust the following two apps, so if new Intel® Desktop Utilities states DDR3-1333 but the other apps state differently go with CPU-z and AIDA64 Extreme.

1. CPU-z - http://www.cpuid.com/softwares/cpu-z.html
2. AIDA64 Extreme - http://www.aida64.com/downloads

Also trust the BIOS, and if it states DDR3-1600 then it's a fair bet you're running DDR3-1600 (800MHz).

Ohh Great my Friend,

Thank you so much, i was confused why OS was detecting as 1333 MHz and BIOS detecting as 1600 MHz, upon your confirmatoion i am mentally peace now.

Thanks a lot !!!
