OC Wit's End - 5930k, MSI SLI Krait

[nserdar9119]

I built a system back in 2016 and have tried now on multiple occasions to OC the following:

Mobo: MSI - X99A SLI KRAIT EDITION
CPU: Intel - Core i7-5930K 3.5GHz 6-Core
RAM: Corsair - Vengeance LPX 16GB (4 x 4GB) DDR4-3000MHz

Full Build Here:

Essentially I am able to boot to BIOS with no issues regardless of any changes under the OC menu. The issue is that when I boot to Win 10 after making ANY changes, I check CPU-Z and my multiplier is stuck at 12x even under stress. Here is a basic list of things I've tried changing or toggling (together and separately) to get even the smallest OC:
-Power management set to 100% CPU min
-Disabled EIST
-Changed between Fixed and Dynamic modes (Incl. Turbo Boost and Enhanced Turbo)
-Tried OCing with and without XMB
-OCing with multiplier and/or bclock (especially as XMB for 3000MHz RAM changes bclock to 125.03)
-Amending voltages: VCCIN, up to 1.999v; CPU Core up to 1.3v in most modes (Override, Override+Offset, etc.); Set RAM to 1.35v and messed with other voltages i.e. SA CPU and Ring
-Tried using OC Genie both stock profiles

BIOS will display up to 4.5GHz but in CPU-Z I am always capped at <bclock> x 12= XXXX.XX GHz. Also, temp seems to never have been over ~50C.
I'd say I have mid level experience, and am wondering if I have missed something blatant, or I am not sure what... Any assistance would be greatly appreciated!

EDIT:
Shown in the photos below are of the last attempt at OC I made. I had already tried another config., so I may have forgot to change something back again for the pic as I didn't save the profile... Also in the photos is the resulting CPUZ screenshot after the changes shown were saved. (In the BIOS screenshots the information at top right is a different OC attempt).

Also I ran Ubuntu from a USB drive and through the terminal it would appear it is also stuck at a 12x multiplier even in Linux.

I know this build is almost 2 years old, but hopefully someone is still interested in helping... I feel like I've scoured all the interwebs for this set of issues. None quite fit what I've got going on so please help!!! Thanks in advance.

Bump for please help...

Have you tried updating latest bios?
Tried older bios?
One stick of ram?

I belive this is your hope, READ WHOLE POST!

Thank you so much for your response!!
I tried original BIOS and 2 other versions as well, including the most current.
I did also try 2 sticks of ram in 6 different paired configurations (have 4 sticks total). Should I try just one?

Do you think it's possibly something to do with my ram? Even though at the x99 default of 2133MHz (correlating bclock of 100) amending the multiplier locks it at 12x? I sort of figured the reason why XMB locked me up was because it changed the bclock to 125.03. On that note though, I'm pretty sure ram is stable because with just XMB on the bclock is accurately displayed in cpuz. (Without XMB on but OC is attempted at bclock 100 it locks multiplier at 12 and the resulting total in cpuz is 1200MHz, but with XMB on even with stock multiplier the bclock is 125.03 but the locked multiplier of 12 nets 1500MHz.)

Sorry that last part was long winded...

Two other things possibly worth mentioning are
1.) In cpuz, when stable, the NB speed for ram hits 3000 when ram lists at what it should (1/2 of BIOS spec'd speed i.e. 2133 shows as 1066, which is fine). But when the multiplier locks, the ram speed is still listed correctly, but the NB locks out at the top CPU speed.
2.) Cpuz list the multiplier range of 12x up to say 36x or whatever it is set to in the BIOS, but it never goes above 12x even under stress.

I did see some other things in that thread that I will try and get back!

Thanks so much again!

So the BIOS version that he obtained in that thread you linked is the version I am currently running already. I tried setting the core multipliers separately again, still same result. As far as the Intel Turbo Boost Max, that is not an issue with Broadwell-E processors I believe. I checked to be sure, and my processor is not listed on their site as compatible. Is there something else on that thread I missed?

"You'll need the most up to date BIOS I believe, and you'll have to enabled TBM 3.0 (Turbo Boost Max), and set the max speed for EACH CORE separately I believe, in order to get it to boost properly..... Blame Intel and MSI for this problem. Intel because they leave it up to the motherboard manufacturer on how to handle it, and MSI for automatically disabling it in the BIOS as default."

I have the current BIOS.

TBM 3.0 is not for Haswell E processors. (That thread is for a Broadwell E)
(https://ark.intel.com/products/82931/Intel-Core-i7-5930...)

I have set each core separately, with the same results.

Bump for last ditch attempt! Thanks!

I think mostly thats with motherboard bios issue, as stated in some forums when MSI made motherboard they didn't care about it.
You can only play with it and figure out by yourself or if someone has/had/have this motherboard and help you.

Or go for MSI support.
