Memory mhz, depends on cpu?

[Metalwell]

Hey guys, I have ordered 3000mhz rams, my mobo supports upto 34xx however i7 6700k says it support up to 2133mhz, will there be a problem on running? thank you

 

[JackNaylorPE]

No, none whatsoever....Intel plays a silly game where it lists the "official" rating of the CPU and then it "officially supports" XMP and published a list of certified compatible memory modules that go up way way over 2133..]

You will have to configure DRAM speed in BIOS, assuming your motherboard is capable of running memory at overclock speeds.

What is the make and model of your board?

Will it work? Yes. Will it run at 3GHz by default? No, that needs to be configured.

Thanks for the bot replies, I have Gigabyte Z170X Gaming 3, I would be glad if i could find a link that shows me how to overclock it, and do you think that oc'ing ram might damage anything ?

Its simple.... Open BIOS and Set the Memory speed to XMP. Whatever the speed is in the ads and on the package, that is the XMP speed.

See page 25 of the manual.

Here's your manual. Start at page 23 (in the English version).

Assuming he bought XMP memory

 

[JackNaylorPE]

Its is ... by definition.....can't have 3000 MHz on Intel platform w/o it being exist only as XMP.

 

[weberdarren97]

Okay, I didn't know that.

You learn something everyday, especially when you're around a whole bunch of techies.

Wait, I'm kind of lost here, My mobo supports that XMP right? So I can overclock that by reading the manual. I still wonder if this damages the cpu in anyway ^^

 

[weberdarren97]

Does not damage CPU at all.

CPU will be unaffected by this, other than <1% of its clock being used to keep up with the memory.

No risk to CPU. Yes, your board supports XMP.

 

[JackNaylorPE]

RAM is built according to a spec called JEDEC. These specs take ages to be developed and approved and by the time a product is released technology is way ahead. When DDR3 came out 1333 was JEDEC everything else above starting with 1600 was XMP. JEDEC eventually got up to 1866 (IIRC) and everything beyond that was XMP.

Yes, your MoBo supports XMP, which should be obvious if you opened your manual or BIOS. It would not have a XMP setting in the BIOS or have a manual which describes how to set it, if it didn't support XMP.

Your MoBo manufacturer wouldn't have the instructions in the manual or provide the BIOS setting if it would break the CPU. Intel wouldn't have 3,000 ... 3,466 MHz RAM on its officially certified i5 / i7 compatibility list if it would break the CPU.

Read the manual as well as the above provided links, the answer and directions are all there.

Just wanted to make sure OP understands, the word not is very important when it comes to understanding whether something will work or not.

fixed

 

[Metalwell]

Thanks a bunch both of you guys! I mispelled that ı will get the mobo the day after tomorrow, so I dont have a manual in my hand! However you both been helpful to me to clarify this in my mind thanks a buuunch !!

 

[weberdarren97]

Take a look at my second response, I linked your manual (in blue text)

For information purposes: Just because the mobo supports XMP and 3000 DRAM doesn't guarantee anything. The determining factor is your individual CPU, in particular the MC (memory controller) in the CPU. Many still believe that the mobo is the determining factor in what DRAM you can run (and at what freqs/data rates, which went out about 6+ years ago, with the demise of the socket 775 mobos. While many6700Ks will carry 3000 DRAM, at stock not all will, have seen a couple that couldn't run 2800 at stock let alone 3000. If you try and have any problems, you may need to increase voltage to the MC and/or may need a slight OC on the CPU to run at 3000. If any problems give a shout and let us know, hopefully you'll have a good CPU and there will be no problems, but it's not always as simple as the above answers make it sound.
