Skylake XMP Memory Overclock - not posting

Hey,

 

I've tried to find a solution for my problem, but none of threads I came across was helpful.

 

I have an Intel i5 6600k, Asus Z170-A Motherboard and Corsair DDR4 3000MHz CL15 Vengeance LPX memory. All drivers and BIOS updated. 

I'm in process of overclocking and the CPU OC works fine, no problems there. But when I try to overclock the memory from 2133MHz to 3000MHz, which it is rated for, I always get "Failed Overclock" error message during booting. I tried manual raises of VCCIO and CPU System Agent voltages as well as RAM voltage, but it did not help. 

 

Can anybody help me? :)

Thanks!

To run the memory at it's rated speed all you need to do is to turn XMP on in the BIOS.

Forgot to mention that, I have XMP turned on and I tried the predefined profile as well as raises (with XMP still on) afterwards.

Well all you need to do is select profile 1 and it'll run at it's rated speed.

Did you try overclocking the Ram with XMP without overclocking the CPU?

I think I did only turn XMP on when I first tried the system and it was not running either, but as I needed the computer back then I just switched back to default.. I'll try again to be sure

Yes see if the system will boot with the XMP only without any CPU overclock. Remember that using XMP changes the Baseclock of the CPU.

I tried it and the computer did not post, during second boot it gave me "safe post" and send me to BIOS as it did before..

So either the RAM or XMP/Motherboard appear to be the issue, have you updated it with the latest bios.

yep, up to date

Do you have other ram you can swap to test?

no, but I have 4 dimms installed, can take out two/three and try that?  

Good place to start.

So, I tried the dimms one by one, even in a pair and then in full setup.

 

All dimms are working fine, when not overclocked. I didn't see any issue there, the computer booted from turned off to welcome screen of Windows in about 15 seconds.

 

Problem started when I tried the XMP profile: the boot took all of sudden about 1:15 - about 50 sec of black monitor, then it continued normally - the MB screen (Asus, For accessing BIOS press..) and Windows. On MB error LEDs were shortly on one by one during the 50 sec part - all of them, DRAM/CPU/VGA/BOOT, shined for +- 5 sec then the next one.. What I find really strange is that when XMP was turned on the BIOS was extremely laggy - hard to navigate by mouse, after pressing a F* key it took several seconds to change the screen, the animations were not working.. These problems occurred in any number of dimms installed.

Have you manually overclocked the ram instead of doing a XMP.

yes, the problems of 1/2/4 sticks were exactly same once overclocked

Did you try a earlier version of the Bios

Two things to try, make sure power settings are to to performance, and looking into this one other case with your board had the same issue but it was caused by Speedstep.
