First time overclocking...

Hello.. I have a asus z170 motherboard.. I7 6700k..and a cryorig h7 cooler..and my ram is g skill ripjaw v series 3200.

I habe my voltage set to 1.325 and clock rate set to 4.6. And XMP on for the ram. Cpu runs steady around 68-69°c. When I just change the clockrate to 47..It becomes unstable and bluescreens the system.

Should I try to bring it up further? Do I have to change the voltage?

Sorry..kind of new to overclocking!

  1. Yeah you would need a voltage boost at this point to get a higher OC.That said If it were me I wouldn't want a 24/7 OC with a voltage over 1.33V though I know some folks are fine with up to 1.35/1.36V and even higher. What are you using to test your stability?

  2. Yes, to get up to 4.7 you may need to bump the voltage a notch or two.

    However, with your CPU 'running steady' at 68 or so, This is a little worrying. Is this idle temps? or gaming load, or full load (stress testing). If it's at idle, thats very high so don't push further. If its at gaming load, it's a little high too, but okay. If it's full load stress temps then it's really okay, and you have a little headroom for further OC'ing.

  3. You would have to increase the voltage, not sure what the maximum safe voltage is for 6700K. Reducing RAM speed may help too.

  4. Kieth made a good point. Are these temps under full load or idle? If idle that is a bit high if full load they are fine. I try to keep temps under full load to 75C or less though some users will got 80-85C under full load...and others go the other direction and 65C is max temp under full load. Point being the lower the temps and voltage the longer you CPU will last.

  5. That is the temps at 100% stress load from aida64 and cpu z. At idle it didnt change versus not overclocking.

    These temps are at full load only.

    I would say your temps are really quite good for 1.325v 4.6ghz with that cooler.

  7. I thouggt so too..just wondering if I should push further.. Or how to even.

  8. Yeah your temps are golden then. You have more thermal headroom to OC further it is a question if you're will to run more voltage through your chip long term. I see guys hitting 4.8ghz in the 1.4V+ range with an i7 6700K but as I said earlier I like to keep voltages to 1.33V or less to increase my CPUs longevity. The higher you crank your voltage the quicker it will wear out do to electromigration.

  9. Well..Maybe I could try bumping the voltage from 1.325 to 1.330 and see if it remains srable there? Since this seems to be your golden voltage heh..I was thinking maybe 1.35 and see if it can handle 4.7 ghz..and if not just bring setting to 1.325 and 4.6 and leave it.

    P.S. - Having ram at its advertised mhz can affect the CPU Overclock?

    P.S.S. - The Cryorig H7 Tower Cooler has really good reviews for overclocking actually. Ive read it can handle as well as a lot of water coolers. (But I also read once water coolers dont really do much better than the bigger tower fan coolers)

    Voltage/temps are all about your comfort level. Just know the repercussions of pushing things to far. Instant death...or shorter life span.

    Higher Mhz ram can affect an OC to a degree. First of since the memory controller is built into the CPU itself the faster it runs the hotter it is/more voltage it uses. Pulling from your overall thermal envelope. For the most part though it shouldn't be too much on an issue. It is just worth checking if you hit a GHZ/voltage ceiling to see if lower your ram speed can get you more CPU speed. Always benchmark though, not just stress testing but something like sandrasisoft. Find out your sweet spot for performance. Great example my CPU will hit 4.6Ghz no problem BUT my best overall performance is actually at 4.2ghz. I go faster some scores go up but others that matter more for my usage go down. If I was just gaming the 4.6ghz would be best but for my video editing the 4.2ghz gives me faster encode/decode times. Knowing what to choose to clock your OC at an OC build is just as important as seeing how fast you you can push the CPU.

    As for your solution vs AIO liquid coolers. This is mostly true but there are some high end AIO that will defeat it and once you bring open loop water coolers like mine they crush your thermal performance.
