BEST overclocking guide

[Viper0402]

Followed EXACTLY step-by-step, overclocked my Intel® Core™ i7-9700K Processor (12M Cache, up to 4.90 GHz) to 5.0GHz, rock stable with Corsair H100i All-inOne Liquid Cooler.
Mainboard, Asus ROG STRIX Z390-F GAMING
Rams, G.SKILL Ripjaws V DDR4-3200MHz CL14-14-14-34 1.35V 16GB (2x8GB) - yes RARE fast super-low latency rams at CL14 !
SAPPHIRE NITRO+ Radeon™ RX Vega64 8G HBM2
Transcend SSD230S SATA III 6Gb/s - 1TB SSD
Eizo FORIS FS2333 IPS monitor
Creative Sound Blaster Z
Creative MegaWorks 550THX
Corsair HX1000i model 80+ Platinum high performance 1000W PSU, 10yrs warranty, all Japanese 105°C capacitors.
Corsair Obsidian Series 450D Mid Tower Case
Windows 10 Pro 64-bit 20H2

Idle at 40-42°C , Full load around 80°C & below

if possible very interested to see cinebench R23 + HWinfo results screenshots

Read around that keeping overclocked processor below 75°C will not affect lifespan.
True?

as long as we use it the "lifespan" already shortened just a matter of time. Most importantly is how we utilised it while it's still serving our needs how long lifespan do you expect for a CPU?

Please don't comment BLINDLY thank you

It depends from chip to chip and it’s usually the extra voltages that kills the chips. But in general OC is ok as you said just keep the temps down. It should last you until you upgrade ur pc anyway.

My pc on a sandy bridge processor that’s OC to 4.5Ghz and after 8yrs, it still runs fine, but It has watercooling to keep the temp down.

Wow 4.5GHz...
Previously my i7-3770k only OC to 4.2GHz with Noctua NH-U12S from 2017 to 2021... before that on Intel stock cooler @3.9GHz from 2013 to 2017.

Guys share your OC 5GHz for i7-9700k and i9-9900k CPU temperatures, and what coolers you use.

 

[Viper0402]

Recently change to Noctua NH-D15 with 2X NF-A15 PWM 140mm Fans (Brown), and overclocked i7-9700k at 5GHz now idle at 35-38°C , full load below 70°C, highest 72°C
Sadly due to the G.SKILL Ripjaws V rams, NH-D15 can only use 1x NF-A15 fan... anyway from YouTube review, only 1°C difference between 1 and 2 fans.

Wait till u OC a 99k.... as usual have sufficient cooling and good RAMs....

NZXT Kraken AIO.... idle 43c max 89c ambient

More than voltages and temps, current actually kills you CPU more.
Intel spec sheet usually has a max of 1.52V but I personally would recommend under 1.4V for daily.
Some CPUs like Rocketlake are okay with voltages up to 1.45V.

Do not use an aggressive LLC. Somewhere in the middle or less would be good to prevent an overshoot in voltages. This also ensures you have good transient voltages making your system much more stable as too low voltages with high LLC has issues with some games like Apex Legends where Vmin creates alot of instabilities and crashes.

I was able to do 5.2GHz all core on my previous 9900KS at 1.37V with 4.8GHz cache with 4,133MHz CL16 tuned rams. Custom loop with temps around low 70s during gaming and idle low 30s. LLC was High with the Gigabyte Z390 Aorus Master.

5.0GHz - 1.31V
5.1GHz - 1.34V
5.2GHz - 1.37V

Hope this helps...
