    What effect does using 3000MHz DDR4 RAM have on an i7-6700k?


      My setup:

      Processor: Intel Core I7-6700K @ 4GHz

      Cooler: Corsair Hydro Series H90

      Motherboard: MSI Z170A XPower Gaming Titanium Edition

      RAM: Corsair Dominator Platinum 16GB DDR4 24000 (CMD16GX4M2B3000C15)

      PSU: Corsair HX850 850W 80PLUS

      GPU: MSI GTX 980 Gaming 4G LE

      Sound: SB Recon3D Fatal1ty Pro

      Optical: Samsung SH-222BB/BEBE

      HDD0: OCZ Trion 150 SSD

      HDD1: WD Velociraptor 300

      HDD2: WD Raptor 150

      HDD3: Seagate 1TB

      HDD4: Seagate 1TB

      OS: Windows 10 Pro 1607

      Case: Thermaltake Level 10 GT (AWESOME!!!)


      When I built this setup end of 12/2016, I really wasn't planning on overclocking. I just like to buy higher end hardware for proper and solid operation. However, I started having clock_watchdog_timeouts BSODs and freezing happening, about 5 months of solid PC use. I noticed a high amount of WHEA-logger Event ID 19 errors in the System Event log related to APIC ID 4 and 5.


      Something to note, I don't generally hard boot my computer. I generally only use soft boots for system sluggishness and odd issues, driver updates, etc. My computer stays on, all the time.


      So, I started doing doing some investigating and found that it could be core 4 and 5 failing.


      Long story short. RMA'd the processor and I'm back up and running. Did a Prime95 stress test overnight and system is working properly now.

      Since the processor only has a 2,133MHz memory controller, what is the effect of running RAM at 3,000MHz on that processor/memory controller? Should I overclock/upvolt the processor for reliability? Should I just run the RAM at 2,133MHz?


      Suggestions/Comments welcome.
