Overclocking the i5 8600k

Hey there! I'm going to get a new rig soon and was thinking of overclocking my cpu

I am quite new to cpu overclocking so are these hardware enough to overclock?

Motherboard: MSI Z370 Gaming Plus
CPU: i5-8600k
Cooler: Noctua NH-D15

Was thinking of overclocking to 5ghz, or is that too high? Thanks!

  1. For some serious oc, you may need better mb. Cooler is very good for 8700k, but you can get something cheaper for 8600k since it runs cooler than 8700k.
    I will get this for similar budget:

    PCPartPicker part list / Price breakdown by merchant

    CPU: Intel - Core i5-8600K 3.6GHz 6-Core Processor ($279.89 @ B&H)
    CPU Cooler: CRYORIG - H7 49.0 CFM CPU Cooler ($34.89 @ OutletPC)
    Motherboard: ASRock - Z370 Extreme4 ATX LGA1151 Motherboard ($158.99 @ SuperBiiz)
    Total: $473.77
    Prices include shipping, taxes, and discounts when available

    However, you can keep Noctua if you like.

    hm ...
    you can't know what will be the result of overclocking as it depends on luck with particular CPU that is going to land in your computer.
    I completely agree with vapour that MSI board is a joke when it comes to overclocking due to very basic VRM to begin with.
    Though I think that decent asus board like Z370-A or Z370-F would be better choice. Usually way better BIOS and a much more complete product than Asrock .
    I agree that NH-D15 is a bit overkill, but I honestly doubt that H7 is a good fit for overclocking 95w TDP CPU that can be pushed to 140w easily.
    At least Cryorig H5 or Be Quiet Dark Rock 3 or NH-U14s.

    hmm how about the GIGABYTE Z370 AORUS Ultra Gaming mobo? is that any good?
  4. +1 to n0ns3ns3, I just want to stay similar budget :) better cooling is recommended ~

    yes, it is good. it has RGB and gaming in name. it will be excellent Christmas tree toy.
    For overclocking, there is no decent board below 150$
  6. In that case i'll get the Z370 AORUS and the Cryorig H7, Thanks!
  7. I have the Gigabyte Z370 Ultra Gaming and can confim that it is great. Runs my i5-8600K at 4.9 Out of the box at 1.285v, no problems on XMP, worked first time to 3000MHz and in general has all the bits and pieces required....oh and the RGB does look good too.

    I am not an expert by a long way and have only just started on this journey as well...With a bit of help and some trial and error I have a stable 24/7 4.8GHz overclock that I am happy with at a fairly low vcore. At 4.9 and 5 GHz I have to go upto 1.378vcore...It depends on how high you want to go. First make sure you have XMP to profile 1...if you have good memory i.e 3000+MHz, then change the multiplyer to 47 ( a good place to start) and leave everything else in auto...It should work...Test and note temps..Then to go higher and change to 48, if it fails or temps are to high start adjusting the CPU vCore Loadline calibration to Turbo and adjust the vcore...Please note you have to go to the Advanced Voltage control and change the CPU Core Votage setting to 'Normal' only then can you access the offset mode 'DVID'...here you can fine tune the vcore by using the + or - keys to set a vcore max limit that you are happy with. It adjust up or down, start with a very small value like 0.005 and test again. The CPU gets as much voltage as it needs but it is still dynamic. This is where the trial an error comes in for working out the best ofset for your target.

    You can also just go for a fixed vcore which is easier but thats the vcore that you will have all the time. Again you can do this in advanced voltage settings - CPU Core Voltage...and just type in the vcore you want to start with...say 1.278 and then test and move up or down until you reach stability with temps you are happy with...personlly, I want to say under 1.3ish vcore..others are more than happy with 1.35 and even 1.4 to hit 5GHz...Some can hit 5GHz with a low vcore around 1.3 but mine needs just a little more...silicon lottery..

    hope this helps and hopefully others will chime in as well as I am sure others better than me will have some thoughts on the best way to do things..Good luck
  10. Oh, I forgot to mention that I am on the F6 Bios which is the latest one and I have found it good and stable.
  11. My Bios settings for 4.8GHZ overclock on the Ultra Gaming:

    Everything else in auto other than:

    CPU multiplyer to 48
    LLC to High
    Vcore to 1.265v - I am going to test at 1.260 and will update...you might need more

    I have disabled Intel Speed shift and C1, c3, c6/7, c8 and c10...Though you dont need to and can go for an ofset vcore..

    This is a great place to start for our bios: https://overclocking.guide/gigabyte-z370-overclocking-coffee-lake/
  12. Further bios update dropped to 1.260v and stable at 4.8GHz will go for lower and update further..
