My Intel i7 8700 causes latency when Hyperthreading is ON


Hi Everyone,

I've been experienced for a few years some latency when I play my favorite FPS game, PUBG in this case so in the last month i try to observe better the behavior inside the game. So, when start the game it runs very well, good frame average video fps, CPU i7 8700 when nothing is happening over scenario then when combat suddenly beggins some lag occurs, caused by some unknown event until now. First of all I'm am a software developer so a reached the conclusion of some lag occurs when threads are runnings and suddenly some context change happens and some cache trash could happen too.  After problem analysis I try to change some hardware setup and I realize that i had a non-k processor, so i found a non-K override overclock options for maximum gaming perfomance (PUBG in this case)


My Setup:

  • Power Supply : Corsair 650W 80 Plus Bronze CX650

  • Cooler Solution : Corsair h115i Watercooler

  • Motherboard : ASUS ROG STRIX Z370-G m-atx

  • Memory: KINGSTON HYPERX PREDATOR 8GB 3000Mhz DDR4 (Qualified Vendor List)

  • CPU: Intel I7 8700 Coffee Lake 8th generation

  • Videocard: NVIDIA GeForce GTX 1070 Ti Galax Edition 8 GB GDDR5


UEFI Setup

  • Power Mode : Performance

  • HyperThreading : OFF

  • Turbo Boost : ON

  • Prefetch : OFF

  • Cache Prefetch : OFF

  • Maximum Processor Frequency: based on processor specs (picture above)

  • Base memory clock: 102.3Mhz (XMP 2.0 3000Mhz profile Memory Clock)

  • 1 core multiplier: 45x

  • 2 core multiplier: 44x

  • 3 core multiplier: 43x

  • 4 core multiplier: 42x

  • 5 core multiplier: 42x

  • 6 core multiplier: 42x

  • Minimum Processor Frequency: 6 core multiplier: 42x

  • Minimum Cache multiplier: 38x

  • Maximum Cache multiplier: 38x

  • CPU Voltage Offset: - 0.075V (minus)

  • Intel SpeedShift: OFF

  • Intel Speedstep: OFF

  • CPU C-STATE : C0 CPU fully operational

  • CPU parking: OFF using ParkControl software

With this message i want to provide some information to improve intel chips that are always best for me and if you desire so i would like to test my machine with other CPU like  I7 9700, i7 9700k or I9900K is it possible?

Hello Rafael007BR,


Thank you for posting on the Intel️® communities. We appreciate your efforts in investigating this issue. We would be more than glad to help you.


We understand that you are having trouble with performance when playing PUBG, and you would like to test your system with other CPUs. Please note, that if you are requesting us to provide you with the CPUs. Unfortunately, we don't send processors for testing purposes. We only offer engineering sample processors that are generally only loaned to OEMs, ODMs, and ISVs for pre-production test and evaluation work under specific contractual terms and conditions to assure the protection of assets and confidential information. They are not made available to the general public by Intel.


We're here to assist you in identifying the root cause of your issue. We'll explore whether the problem is due to a faulty processor or if it's influenced by another component within your system.


Also, you mentioned that you are using a non-K override overclock option. It is important to mention that altering clock frequency or voltage may void any product warranties and reduce the stability, security, performance, and life of the processor and other components.
