8700k @ 5.3 13.7v

Hi got my 8700k running 5.3 i can boot into windows @ 5.4 but unstable in prime 95 shall I delid ?

  1. Are temps causing shutoff or is it just unstable?
    In other words what temps are you seeing when you are testing?
    If you aren't using HWMonitor or another monitoring software you should be.

    If temps are causing shutdown/throttling then yes a delid would help,

    And hopefully you mean 1.37V not 13.7V :D

    You'll need to up the voltage A LOT to see stable 5.3GHz.
    Chances are you're going to hit the thermal limit FAR before that.

    Last bit of info. If you are not using Prime95 version 26.6 you should be. That's the only version of Prime 95 I see anyone around here ever recommend for stress testing.
  2. Delidding only helps temperatures, not stability. If you're having stability problems, you need to put in more voltage, which will raise temperatures even more. If your CPU is running too hot and you already have top tier cooling, then delidding can help. If you're already running at 1.37V, you probably should just stop there. The absolute max voltage you should be using is 1.4V, and even that is probably a bit too high for long term daily use. Odds are even if you did push up to 1.4V, 5.4GHz still wouldn't be stable, you're up to clockspeeds where you need a really good chip to get stability without pushing past the safe voltages and breaking out the exotic cooling.

  4. Sorry yes 1.3 it's ok at 5.3 but temps are spiking 86c to 90 c@ 5.4 and crashing I know 5.3 is a very good clock I and i am happy with it but more is more lol is it a big risk deliding looks simple enough ...
  5. So you're already pretty close to TJmax, which you want to avoid, because that's when throttling kicks in.

    If it's crashing/freezing, the OC is unstable, you will need to increase the voltage.

    Since you are already close to max thermals, you will need to delid to increase the voltage any further.
    Again I recommend making sure that you are using Prime 95 version 26.6, as further version unnecessarily overheat the CPU. I personally use Asus RealBench as that is what Intel employees recommend as that is what they said is the closest to the programs they use for thermal testing CPUs. You might have just a tad more room on thermals than you think.

    However, If I were in your shoes I would just clock down to whatever is stable at that voltage.

    There's not much you would be doing where you would see a big difference in 100-200MHz.
    But that's your call. 5.1GHz on 6cores/12threads is still insanely fast for gaming or anything else for that matter.

  7. It's stable @ 1.37v 5.3 and like you have said I'm not going to get much more out of it. 5.5 sound really good but its a new set up so maybe wait 6 months a year in till I'm board and then try it .what is the bios setting Multiple core enhancement called on gigabyte board iv heard this can make a massive difference?
  8. If it's truly stable at 5.3GHz at 1.37V you won the freaking jackpot. Silicon Lottery is selling chips that hit 5.3GHz at 1.43V for over $800

    I wouldn't mess with it, that thing is a gem if you're able to do that.

    I'm actually quite jealous.

    Congrats.


    As far as the BIOS setting. sounds like what I have on my Asus board. Asus Multi-core enhancement. On mine it tweaks settings on its own. In my experience its a bad idea. Any software that messes with OC settings on its own generally makes it more unstable not more stable or better in any way.

    Quite frankly if I got a 5.3GHz stable OC with those temps and that VCore I would never touch any setting. That sounds too good to be true.

  10. It's true it will boot In to windows 3.4 .but not stable when gaming it was doing 3.2 on a £20 cooler I bought In till I finished my loop...
    Im happy with it but you alway want more
  11. Well if it's not stable for gaming it's not stable :D.

    I guess if you want to make it stable, I would increase that voltage or lower the clock.

    Its better to go and make your 5.3 GHz fully stable than to proceed for an unstable 5.4 GHz.

    Raise your volts up to a max of 1.45V, and temps not exceeding 100°C on stress test.

    If it can run Intel Burn Test Standard 10 runs/Prime 95 30 minutes/ 20 runs of Cinebench without crashing, you are probably 99.9% stable.

    And stable CPUs produce less errors. Your higher OC might be throwing out so many errors until your CPU slows down.

    Stabilise your OC first. If 5.3 cannot be stabilised, Set it to 5.2 GHz and call it a good day of overclocking. 5.2 is 1.5 GHz above stock 3.7, which is really good.
