Bought a new CPU today and a new motherboard to go with it. I got an intel Core i9-9900k and an Asus Maximus XI Hero. After installing the new mobo and cpu I booted the system and everything boots and launches fine. The problem I am having is that the system is unstable, with windows lagging and basically every program and game lagging as well. CPU usage was also unusually high (around 40% after booting with minimal amount of processes running). The first thing I realized is that the cpu was automatically overclocked by the the mobo’s BIOS (from 3.6GHz to 5.0GHz), so I went into bios and turned off turbo mode to get it to its factory setting. After booting again, I confirmed the cpu was running at its factory clock, however the lag persisted. I figured this was the issue, but apparently not. Resetting bios to default settings turns on turbo mode on the CPU, so that option doesn’t work for me. Below is a list of my previous and new specs.
Previous: Intel core i7 5820K Asus Rampage V Extreme Corsair vengeance 32gb 2400MHz Evga GeForce GTX 1070 SC
New: Intel core i9-9900k Asus Maximus XI Hero Corsair vengeance 32gb 2400MHz (Same ram) Evga GeForce GTX 1070 SC (Same gpu)
I can confirm I have an adequate power supply that works fine, as well as a cpu cooler that also works good (Corsair H100i v2) that I also used with my previous components.
Before the upgrade, my PC had no issues. Everything worked crystal clear and I regularly maintained it by making sure everything was always up to date such as drivers, software and firmware. Also made sure to regularly clean from dust to prevent thermal throttle. What I’m trying to say here is that there is nothing evident to me that anything else from my pc could be causing this issue as everything was perfect before.
In terms of fixing, I also made sure the cpu cooler was attached properly and bought a brand new thermal paste. Thermals seem to be fine as the cpu did not go over around 45C.
I also tried using ASUS AI Suite 3 to get it to tune my CPU to its optimal settings, but even that doesn’t change anything.
Could it be possible that the cpu is damaged or not installed properly or some type of hardware problem or is that just me panicking about the CPU’s hefty price tag?
Any suggestions and troubleshooting steps would be appreciated. Thanks.
