For XMP stability it should be acceptable. Consider adding a fan to observe improved stability, though this isn't something I anticipate causing problems.
It's really annoying dealing with these problems. Are you wondering if the issue might be related to your ASUS BIOS? Could using an MSI Z790 Carbon WiFi board help?
I wouldn't be surprised by this being an ASUS BIOS problem. I recall a few other reports about faster kits failing on ASUS boards, while MSI boards haven't been mentioned much, so it seems more likely to be a minor issue. Still, I'm not certain and it might just be because more people are using ASUS boards. I’m sure the Z790 Master is solid for memory support—7200MT/s with an A die kit is straightforward, and 7000MT/s is achievable with an M die kit in 2x16GB setups. Its price matches the Z790 Carbon, making it a safer choice. If you prefer MSI's BIOS or other features of the Carbon, it remains decent, though the Z690 Unify-X offers better memory compatibility overall. It has some downsides: maximum memory limit, no iGPU support for QuickSync, and only one fewer rear Type C port. That still makes it a strong option.
I've steered clear of Gigabyte boards from the 12th generation. A Z690 Master caused issues—CPU throttling even when idle. Eventually, I had to part with it. There are also warnings about Gigabyte's reliability for Intel 12th Gen CPUs and RAM stability. Maybe a switch to MSI would be safer, as they seem to lead in Intel 12th Gen performance. For 13th Gen, I'm still unsure. That's why I'm considering MSI based on their strong track record with Intel.
They performed well against the Z790, and their Z790 boards offer superior performance compared to Z690. Their DDR5 options are now worth considering. I’d still favor a Unify-X if you don’t require 10GbE LAN, though I wouldn’t skip the Z790 lineup either.
It's quite unexpected since I believed Raptor Lake improved upon Alder Lake with enhanced binning, more L3 cache, and a modest increase in IPC. I expected Z790 to have been straightforward to run with stable DDR5 support. Unfortunately, it hasn't turned out that way and has been quite challenging for me.
Considering AM5 starts having problems above 6400MHz, Raptor Lake still isn't that bad in memory speeds, but I would give the platform some time to mature - check out new BIOS releases as they come out, they may improve memory compatibility. Technically it's all overclocking, so it's not guaranteed to work.
It seems odd since they promote XMP RAM performance, leading you to believe everything will function smoothly despite the fact that it's being overclocked.
