Here are my PC's specs:

Processor: Intel® Core™ i7-6800K Processor (6x 3.40GHz/15MB L3 Cache)
CPU Cooler: Corsair Hydro Series H55 120mm Liquid CPU Cooler
Memory: 64 GB RAM [16 GB x4 DDR4-3200 Memory Module]
GPU: GTX 1080 MSI GAMING x 2 (Dual Cards with EVGA SLI Bridge)
Motherboard: MSI X99A Gaming Pro Carbon (4x PCIe x16, 2x USB 3.1 Gen 2, 4x USB 3.1 Gen 1, 4x USB 2.0 - Mystic Light RGB LED, Steel Armor PCI-Express Slots 3)
Power Supply: 1000 Watt EVGA 1000 GQ
Primary Hard Drive: 512GB Samsung 950 PRO M.2 PCI-E SSD
Secondary Drive: 1 TB HARD DRIVE

I don't know much about overclocking so I decided to use MSI's inbuilt "gaming boost" option to automatically overclock my i7 6800k. There are 11 presets and even with the preset set to 1 -- the lowest possible oc setting -- I run into this problem where the PC will not boot up... It does not even load the bios (the monitor gets no signal). After spamming the physical reset button on the motherboard over and over, I eventually get a message saying the overclock has failed, press f2 to return the motherboard to default settings. I tried updating/flashing the bios to a newer version as well, but this didn't help either. So what could be causing this? As far as I understand, voltage is automatically changed for you with the presets as well (correct me if I'm wrong) so that shouldn't be a problem either. So what do you recommend that I do?

Also, I currently have xmp set to enabled. It doesn't seem to cause any issues so I've left it on. Could that be the problem?

Your sample maybe different from working overclocked sample, try old school as its working on my gigabyte x99 gaming m5 on i7 6900K
  • ■ Go to BIOS, use default BIOS value, from here we're gonna slowly raise voltage to find out cpu+mobo power delivery.
    ■ disable energy saving (I don't have MSI board but usually labeled as C1E/EIST )
    ■ disable turbo boost
    ■ save and exit BIOS, now try gaming boost, if persist, then we're going to do manual tweaking.
    ■ increase cpu vid by .01 (+ 0.01 v) and multiplier by 2, save & exit BIOS, run program or game to find out stability, usually an hour will do it, restart.
    ■ increase cpu vid ( if you feeling lucky try bigger such as + .1 [0.1 v]), and multiplier by 3. Save & exit BIOS, run program or game.
FYI, some programs may not use all available cores/threads, usually four cores + latest mainstream GPU is enough to run newer game titles ( you can set how many cores that Windows use). Some program do use all available cores such as Adobe Premiere.

  • ■ You can tell that manual tweaking at certain preset is not working when boot/POST failed, freeze on Windows logon screen, BSOD, program freeze, unresponsive mouse/keyboard, loading program become longer, etc.
    ■ You know that previous preset working, so that preset will be your stable OC.
Improving OC

  • ■ water cooling, bigger radiator+faster fans.
    ■ full water cooling, include VRM water cooling and known good CPU water block

Thank you so much, your suggestion to disable turbo boost and power saving (along with increasing the vcore) did the trick! I'm just curious tho -- there were a ton of other cpu voltage tweaking options including vccin, sa voltage, and a bunch more that I can't remember. If I go for a higher overclock -- say something like 4.4 ghz -- do I only need to increase only the vcore voltage or do I have to increase each one to maintain stability?

Base on my experience, only VID tweaking usually suffice, others such as VCCIN, aS V, etc are VRM related (adjusting VID automatically change the rest of VRM setting), sadly neither motherboard vendor nor International Rectifier (best motherboard power component vendor, X99A Gaming Pro Carbon probably use it) don't supply enough documentation. The easiest way to find out how high your motherboard able to supply stable power is by the choke/inductor count (loose the heatspreader near CPU socket), usually eight of 'em consider to be OCable ready, ten to tweleve or above is enthusiast grade board (Intel's reference only has 4+1 phase power).
I wouldn't recommend retrying a failed preset all over again even with known good water cooler, I'm curious, are you doing this to speed up gaming, 3D rendering, trans-coding, etc? I may provide software-side enhancement instead. For example, if you mostly doing office and web surfing then you can choose only use two cores (run msconfig, select advance option under boot tab, select 2 on number of processor).

Had my 6900K at 4.4GHz stable for 15 minutes LUX hybrid rendering (took 34 min with stock speed), oddly after that failed at encoding using Handbrake, so I downclocked to 4.0GHz and turn out to be stable.
