ASUS MOBO compatible with i9 9900K processor
Gigabyte provides two options for configuring RGB: via the BIOS or using their RGB Fusion Software. While the software isn’t necessarily the top choice, the BIOS functions quite well—though any Aorus board might offer better power phasing and VRM compared to some Maximums Hero XI models. Once you know you have a Taichi, this discussion becomes less relevant, so just use that instead.
I don't understand why the PC feels slow after installing the 9900k. If I switch back to the 9700k it seems smoother. I've tried everything, but it's still lagging with the 9900k. I tested it on another PC and it worked perfectly. When I bought the PC, I didn't want any bad components, so I chose the 9900k thinking I'd upgrade later. I only fully trusted the ASRock at that time.
You're asking about lagging performance and wondering if it's related to your Windows installation. It seems like the issue might be with how the operating system adjusts to the new CPU, rather than the motherboard itself. Also, you're questioning whether upgrading from a 9700K to a 9900K was necessary, especially since newer chipsets support 10nm technology.
I basically secured the deal by swapping the i7 for a new i9 at the same cost, which is why I reinstalled Windows after making those changes. However, when I power on the PC and move my mouse across the desktop, the blue squares sometimes appear, causing stuttering or lag—even after releasing the mouse button. Opening certain folders on the M2 disk takes longer than usual.
Occasionally certain games experience lag. Normally playing LoL works fine, but the second one often has issues—FPS drops below 250, sometimes around 15-20. The same happens with World of Tanks and PUBG; newer titles require more powerful PCs for smooth performance.
They are earlier models. The IX is a Z170 board released in 2016 that I installed with my i7 6700k. The X is a Z370 board launched in 2017, which I use for my six-core CPUs. Their VRMs were sufficient for the CPUs available then, but even the Hero X included a VRM fan bracket. The eight-core setup changed things. The issue is managing heat over time. On a bench or in a high-flow case it probably won’t be a problem, but for a neat build in a sealed environment it might matter.
The i7 9700K often needs special handling in certain games to maintain performance. Even older titles like RDR2 encounter this challenge. It's a recognized problem with available solutions. I get why you'd consider replacing it—my own experience shows the i7 8700K couldn't hit 5GHz and caused daily issues.
I believe the heat shouldn't be an issue. My setup includes a CORSAIR H115i PLATINUM, two CORSAIR LL140 units on top, a single 120mm fan on the back, and I'm using an FD Mashify S2.
