Mine ran fine with XMP settings at 7200. I am running 7800 now but with some adjustments to the voltages. Dependent on board and IMC though. You have to be prepared to tune it some and deal with crashes depending on the ability of your hardware. It differs from system to system.
GSkill is what I have used the last several years.
My rule is to opt for a kit present on the motherboard QVL 2-3 bins below the maximum validated frequency for the best chance of plug-and-play. If aiming for maximum validation the margins can be quite tight depending on the strength of the CPU's memory controller.
The AI Tweaker menu now lets you assess the strength of the IMC. This will give you a rough indicator of what to expect. A score of between 75-85 is considered strong. Note the score may differ a few points between runs as certain conditions impact the test assessing the signal lines.
