Memory running at 1333Mhz instead of 1600 Mhz

Hi guys,

One tech question i have this PC:

1) Asus P8Z68-V Pro/Gen3 (It says it accepts 1600Mhz without OC)
https://www.asus.com/Motherboards/P8...pecifications/
2) Intel 3770k (Accepts 1600Mhz memory Dual Channel)
3) RAM 8G Memory DDR3 8GB 1600Mhz Kingston HyperX Fury HX316C10F/8 Blue

By default my pc memory is running at 1333 Mhz since 3 years ago, if i want the memory to run at 1600 that would be overclocking despite the mobo says it supports 1600 without OC?

Cheers

Did you try loading XMP values in BIOS or setting them to Auto? If it doesn't change just modify the multiplier if such setting is applicable.

Hi, i use my bios by default, Memory frequency says: auto. and the value on bios currently is 1333Mhz.

If i change that value to 1600Mhz manually, would that be overclocking?

As GokAy says, try to set memory at XMP mode in BIOS.
Enter BIOS advanced mode, go to Ai Tweaker tab, click Ai Overclock Tuner and choose XMP.
Targer DRAM speed should be set at 1600 MHz then.

Yep XMP will do it, you need to look for these settings:

Not if the RAM is rated at 1600Mhz. You don't need to manually change it if you have the XMP option available.

Thanks Guys.

Now i'm afraid to fry my machine, i guess i'm gonna leave it by default at 1333Mhz, I was just curious a relative bought an imac 5k last week, the box says 8Gb DDR RAM at 1600 Mhz, i was wondering why that machine was running at those speeds without overclocking by default...perhaps is the haswell architecture? i assume that is 1600Mhz by default?

Who defines the architecture the mobo or the processor? As far as i know its the MOBO so mine is sandy bridge but my processor is ivy bridge. i've been told the sandy bridge architecture has memory speeds at 1333 Mhz by default.

There's no risk on setting the XMP profile to run your RAM at 1600MHz. I have the Kingston HyperX Genesis and had to set my XMP profile to run at 1600MHz as it was only running at 1333MHz. 1333MHz is the default setting that RAM will run at when installed, that's what XMP profiles are there for.

You won't fry your PC, but up to you of course. You won't notice any difference anyway I believe.
