Consider your system's needs and the condition of your current motherboard before deciding.
Ok so basically, my motherboard has a few issues that make it very annoying to use. And ive had these issues since ive bought it, ive also been through multiple bios updates and at least 1 windows reinstall since then so theres no fixing it. issue 1: One issue is that sometimes it wont boot into windows properly, like you will see the spinning dots but then it just freezes there until you power it off and on again, usually it wont do this, but other times it will do it multiple times in a row. And also sleep/hibernation and fast startup are disabled, I always shut my system down completely when not in use. issue 2: Memory training takes a very long time, like 1-3 minutes when changing ram timings. I know this is an issue with ddr5 but I feel like this is too much. Issue 3: This is more of a minor issue but it doesnt overclock that well, particularly with memory which is hard to get stable at higher frequencies. The max I can get stable is only 7400 but I want to go higher. Mobo: gigabyte z790 aorus elite ax, bios version f9. There is version f10b but I think thats a beta bios which id prefer not to install. My mistake is I keep buying gigabyte boards, Ive had multiple in the past and they always pull this type of crap. And I doubt gigabyte is gonna accept an rma for this because of how crap their customer service is. My plan is to just sell this board and buy an asus z790 apex encore, what do you guys think? Cpu: 14900kf 5.9 all core, 5.1 ring, 1.41v, e-core and ht disabled ram: 2x16 trident z5 hynix a die 7400 cl34 w/ tuned subtimings 1.45v gpu: msi 4090 gaming x trio And yes I have tried using it at stock, it doesnt do anything.
This Intel 13th gen chip, often called the 14900K, performs best around 6000MHz and can be unstable at higher speeds. It uses a dual memory design that doesn’t work well with very fast DDR5 RAM. Pushing it too hard leads to typical problems. Since the memory controller is built into the CPU, other boards are unlikely to outperform it. You’re exceeding its intended capabilities with memory that’s prone to issues on both Intel and AMD platforms.
The memory controller resides on the CPU. Although the motherboard traces affect performance, the CPU plays a more significant role in overclocking memory currently. The main fix appears to be reducing your memory overclock settings. You might need to disable XMP entirely, as some 13th and 14th generation Intel controllers can support up to DDR5-7200, but others may not. Your CPU could remain stable only at DDR5-6400 or even lower, since Intel stops validating beyond DDR5-5600.
Initially I thought bringing back stock would solve the problems, but it seems you're misunderstanding the limits for this setup. Many overclockers manage speeds above 7000 to 8000 with the Z790 chipset, especially if the cooling is solid. Mid-7000s are realistic too with a mid-range board like yours.
Does "stock" refer to skipping XMP support? Also, are you asking about the JEDEC DDR5-4800 specifications and timing details?
After clearing the CMOS, everything remained unchanged except the boot device. The problem lies with this board—it has persistent issues that won’t resolve no matter what you do.
