DDR4 Oc issues

[Gilles1991]

i just started getting into building my first custom desktop PC , its all been buttery smooth until i noticed the ram wasn't hitting its sold frequencies. when I turn on the xmp i just get a 10-15 second black screen with a follow up message saying that the overclock has fail. I've also tried manually putting in the lat timing and frequencies and voltage but no luck . (also tried updated BIOS)

Computer specs : Motherboard - msi Z170a titanium edition

                             CPU - i76700k (unlocked)

                             GPU - still need one

The i7 6700k supports DDR4 up to 2133MHz so you will need to underclock it

[SLAYR]

Your motherboard most likely doesn't support 3200MHz ram, so it will downclock to a lower supported frequency, it will make no noticable difference on the performance of the machine though.

All CPUs have a "base" memory frequency as part of Intel's reference specifications. For Skylake and Haswell-E, that's DDR4-2133. For Haswell, it was DDR3-1600. That doesn't mean you can't use faster memory, it will just default to 2133 MHz until you turn on XMP or manually adjust the settings. The Skylake memory controller actually supports DDR4 speeds over 4000 MHz.

The OP's motherboard advertises support for up to DDR4-3866, and I suspect even that might not be a hard limit.

Was this memory purchased as a "quad-channel kit" of 4x16 GB? Normally it wouldn't matter, but I've heard that some memory kits intended for Haswell-E (particularly older kits) are not compatible with Skylake's implementation of XMP. Try dialing in the settings manually. If all else fails and the memory is not stable at it's advertised settings, I'd contact G.skill.

I have the MSI Z170 Gaming M7 motherboard with 64GB of gskill DDR4-3333. All I had to do is enable XMP in the UEFI, reboot and *DING* 3333. Now it has a slight OC at 3416mhz.

 

So your mono supports the speed and ram.

its supports 3600+(OC) frequencies and it only holds cpu socket 1151 so i76500 or i76700. so idk man

i have dual channel. i made sure that the cards were meant for the z170/intel before i purchased the ram. ive also tried  dialing in the setting myself . also i tried just simply switching on the xmp because the profile was apparent in the BIOS

Start with 2 sticks, boot?

Set timings, boot?

 

Try other 2 sticks, boot?

Set timings , boot?

 

Process of elimination.... You may have a bad stick. 

 

 

Also, to remove any other variables , make sure your cpu is at stock speeds. no cache oc, etc.

Hey alpha ! so i tried what you said and i was able to get 1 set of my ddr4 to spec with xmp another set i wasn't so lucky! BUT the first set of ram i neglected do one thing inside my BIOS that i might of helped the second to achieve spec. which switch all the ram DIM linked to auto. that was the only difference regardless i couldn't achieve what i wanted at 3200mhz so i manually tuned it down from 3200mhz to 3100mhz and now all 64GB are working OC'd . ill have to call G.skill about that. im content with 3100mhz for now though.

 

thanks a ton for the help buddy!
