What stable ghz can I reach with a hyper Evo 212 and i7 8700k unlocked?

[nellanella]

I don't plan on getting a new cooler. Also what voltage should I use with the recommend GHz?

Edit, specs if necessary:
980ti acx 2 SC+
16gb ram
Z370 motherboard

Thanks

depends on how good that chip is

start with volrage at stock
disable c states and turbo

bring up the multi til prim95/ibt give errors, or temps peak over 80c
if it gives errors, bring up the core voltage 1 bump at a time and test again
if temps go over 80c stop, max is 100c, 20c overhead for if/when a fan fails

enjoy

I may not mention them all but a few things to change in BIOS if you can to help are:

- Disable ASUS MultiCore Enhancement (If you have an Asus motherboard with this)
- Disable SVID Support
- In External Digi+ Power Control\ CPU Load-line Calibration to Level 5 or level 6
- In Internal CPU Power Managment\ set the Long duration package power limit and short duration package power limit to highest the BIOS will let you by entering 55555 for both
- Set CPU Core/Cache Current Limit Max to highest the BIOS will let you by entering 55555
(This is to help the CPU not throttle down when at high clock speeds and remain stable, but make sure to have good enough cooling.)
- Set Min CPU cache ratio and Max CPU cache ratio to 42 or as close as you can depending on your CPU and motherboard. (If this causes issues keeping overclock stable keep on Auto)
- Disable BCLK Aware Adoptive Voltage

Also mess around with your fan curves, may help keep temps down.

No one can say. Each cpu can vary....we usually call that the silicon lottery. You may be able to get 5.0ghz or higher on that chip or struggle with temps due to high voltage reuired to maintain 4.9.......maybe lower if you were unlucky in the silicon lottery.

Onlyyou can tell by testing what you can get using your setup.

You won't go far with just a hyper evo, depending on the chip maybe 4.4-4.5GHz.

Give it a shot and let us know.

Thanks guys, I'll give around 4.4 a shot and adjust the BIOs

On the 8700K you already get 4.3GHz Turbo mode on all 6 cores, 4.4Ghz on 4-5 cores, 4.600Ghz on 2 cores and 4.7Ghz on 1 core.... a manual overclock to 4.4 won't do anything. You will actually decrease your performance in all but heavily multithreaded, synthetic benchmarks/programs. While your power consumtion goes through the roof for nothing and your CPU's life expectancy shortens..

Isn't it 3.7 stock?

Thats just the base clock speed. By default (with enabled speed step) every intel CPU overclocks itself when needed. And clocks down when idling. You can see that live just by running CPU-Z on the desktop.

That's the base speed. The boost speed is 4.7Ghz but it's only 1 core by default.
Lots of people run all 6 cores at that speed.

Mine is competely stock with all the speed step stuff on, with windows power saving off it reads as 4.3Ghz

[tacoshy]

yes but those ppl dont run it on a "crappy" Hyper 212 Evo. Its highly underspecced for Overclockign an i7-8700K in the first palce. Not the best chosie for stock settings aswell.

it was good for the old 4-cores and even there with more then 40% lower TDP they werent that good for overclocking.
Unless the OP has a delidded 8700K he will hit the brick heat wall very early.
