Seems like the thermal results very from one review to another so I think we will need to read more reviews to compare. Different review sites used different CPUs and software to stress the coolers.

Mainstream Intel CPUs from Ivy Bridge till the newest Coffee Lake themselves have inefficient stock thermal paste and excessive gap underneath the IHS so these factors also need to be taken into the account. The thermal results won't be as accurate as the ones tested on the enthusiast-class CPUs (ie. 3930K etc) with soldered thermal interface. Furthermore, bigger chips like the 3930K have larger contact surface than the smaller CPUs.

G3D: performs similarly compared to Kraken X62 (based on 4790K)

Vortez: beats Kraken X62 by 13C (based on 3930K)

OC3D: outperforms Kraken X62 by 14.5C (7700K @ 5.0GHz)

Totally agree with you. I think the most resemble one to i7 8700k will be the i7 7700k oc to 5ghz from OCD. The result is astounding.

After all these years, you are still an enthusiastic overclocker who always do a lot of tests and reviews. Really thank you for surviving the "cpu overclocking" thread. And your 8700k bench scores are great, low Vcore @5.0 GHZ!

Thanks for your kind words... ehh without support from you guys this thread will be dead.
Regarding the low vcore 5GHz OC, I think I am just lucky to have found a nice chip.
No need to resell and buy another chip just to bin for better one like the old days.

Did you still buy a lot of chip for lottery back in 4th, 6th gen? Back in our ivy bridge, a lot of people did that! Could it be due to good cooling and you able to lower the vcore to run at around 6x C during bench?

Yes, rechecking my paypal account found that I really wasted a lot of money just to buy from forumers who were willing to let go their good chips. My aim has been 5GHz at low vcore until now lol. Below is the list:

2600K 5.7GHz - $700 USD from XS forumer

3770K 6.75GHz - $600 USD from XS forumer
3770K IMC 2800+ - $450 USD from XS forumer
3770K IMC 2933+ - $480 USD from XS forumer

4770K x2 new - both were bad chips, didn't want to spend money to buy again
6700K x1 new - bad chip, lazy to bin
7700K x4 new - only one of them doing 5GHz @ 1.28v+
8700K x1 new - first chip strikes silicon lottery thumbup.gif

Good cooling is one thing, but most importantly is of course draw of luck in finding a decent chip with low stock voltage (VID).

So, I went ahead and delidded my 8700K. It was super easy with the Rockit 88 delid tool, coupled with Coolaborator's Liquid Pro applied between the CPU Die-IHS and Kryonaut for IHS-waterblock.

I managed to get a 12C drop in the load temperatures at 5GHz @ 1.280v. Because lower temps means less electrical leakage, I think I can still tune the vCore down a bit and go for higher OC like 5.1-5.2GHz.

Delidded 8700K OC @ 5.1GHz requires exponential vCore bump, 1.344v from 1.280v (5.0GHz). Average load core temps registered at 67.5 degrees Celsius, when stressed with Prime95 v29.4 AVX for 3 hours.

5.2GHz @ 1.408v

5.3GHz @ 1.472v

Hi guys, i am new to OC. i am using 8600k with gigabyte aorus 5 and deepcool ex 240 aio. I manage to get 4.5ghz around temperature 78 degree celcius when full load with prime95 without tweaking anything in the bios other than multiplier itself. Any suggestion from here for daily usage? Thanks

Hi bro, welcome to OC club. biggrin.gif
With the auto BIOS settings, you let your motherboard to decide your voltages etc.
Depending on your board, auto CPU voltage (vCore) might be way set way too high than your CPU actually required.
For 4.5GHz, try manually setting the vCore at 1.1-1.2v (chip dependent).
For 5.0GHz OC guide, read this (shared in post #1 of this thread).

hi, i trying to change the setting in my bios but it seemed that it dont let me to change anything about cpu clock ratio those. Any solution to this problem?

First of all, it is advisable to update the BIOS to to the latest version. For your board, F5f: https://www.gigabyte.com/Motherboard/Z370-A...v-10#support-dl

Secondly, you have to go inside BIOS and set manual settings such as CPU core ratio/multiplier, core voltage, Load-line Calibration LLC, disable those power saving features such as C1E etc.

G.Skill TridentZ RGB @ DDR4-4400 CL19 32GB @ 1.50v

But when it comes to Memtest HCl, I only managed to settle at 19-21-21-39-2T @ 1.50v.
Tighter RAM timings will only give errors after a few minutes.

High end rig for sale! rclxms.gif
It would be better if you could list down the parts included as well as some pictures showing the setup etc.
I also noticed you have a WTS thread separately, perhaps you can put up more details there.
