Need help with 6700k skylake cpu

Hey all

I'm a skylake 6700k owner now, one issue I noticed in the bios that my 3200mhz ram was set at 1.5v so I changed it too 1.35v but it shows 1.36v. Its my understand that anything above 1.35v of ram is really bad for the processor?

  1. You are confusing cpu and ram voltages, ddr4 can run from 1.2 or less toa max of 1.5V, since you have a high frequency kit im guessing it ran at a high voltage
    Can you post what model ram you have?
  2. Well generally intel said that anything above DDR3L (1.35V) might be damaging to the skylakes, but that doesn't stop manufacturers from making DDR3 (1.5V) boards with skylake. However yeah its not recommended and no idea why it was set to 1.5v when every ram at 3200 ive seen has been to 1.35v default. What is your memory again?

    Also Ive Overclocked to 4.5ghz and the CPU voltage was around 1.42v by default I set it to 1.26v but cpu z shows cpu voltage use at 1.34v this is confusing me. also whats the max voltage that intel suggested for skylake cpu's?
  4. Well you need to turn off the auto configuration of your board.
  5. Yeah I turned off the auto config for the ram and cpu. Ram set a 1.35v and CPU at 1.26v Im wondering if these numbers are safe?
  6. Safe zones of the CPU are around 1.40V if you stress test, and a bit higher if you are using water cooling, so yeah 1.26v is completely safe. Same goes for the 1.35V of the memory.
  7. Had a nap while running a virus scan I found the pc in a dead state after mashing keys the ouse it rebooted and froze in the bios and in windows, I hope this is because of overclocking and not a bad motherboard or bad ram. Does overclocking sometimes do this as in freezing the system?

    I also get a system freeze when I use the usb ports, sometime last night windows encounted problems with update some chipset drivers, all I remember was it saying that it had to install them one by one on the error then did nothing.

    I set the power for the cpu to auto so far no system crashes Im gonna play some high end games to see if a freeze occurs I dont wanna use less the 4.5ghz on the overclock currently.
  8. Your overclock was not stable with the set voltages you applied. Yes your computer will freeze, crash etc. with an unstable overclock. I dont recommend an auto setting for your cpu voltage when you are overclocking. This allows your voltage to fluctuate too much and sometimes higher then the safe operating voltage for the cpu. It also will effect your cpu temps as they fluctuate so make sure you keep an eye on your temps. You need to apply a set voltage and run some stress tests to determine a stable overclock. I personally would start by setting your cpu voltage to 1.29-1.3 with a 45 multiplier and stress test your system for an hour+. If you dont crash/freeze then you can try dropping the voltage in small increments and test again. I was able to obtain a 4.5ghz OC on mine using 1.26V and 4.6ghz using 1.29V. Every processor is different though and needs to be individually tested for stability.
  9. After the motherboard stating error code 55 which means no ram installed and a number of failed boots I found the last two slots ram to be the only working ones just 24 hours I got this motherboard asus maximus hero 7 and now its broken mad.gif ram wont even go dual channel, this may be a dumb question but will a reformat help? I mean freezing in the bios and ram slots not working cant be driver related?

    Ok thanks ill try that once my ram issue is solved i think it was the cause as I said above.

    An update checked cpu pins, reapplied thermal paste and didnt very tightly apply the cpu cooler this time. Everything is working normally again only changes other then that is im using the xmp profile now and I changed the asus default overclocking method for the intel version in bios. See how things go from here I hope all goes well.
