The z790-e gaming wifi box and manual state 7200+, but asus updated marketing says 7800+. When 7600+ ram was announced, Asus didn't change their hardware, they just updated their online marketing.
Gskill blames the cpu, hiding behind intels 'official' rating of 5600mhz. They also blame the mobo if it's not on their qvl list.
Intel hides behind their official 5600mhz rating. The imc on the cpu can be a silicon lottery bottleneck on ram speeds. Maybe I should try exchanging the cpu next?
Asus is completely silent. They will only listen when mobos are being returned at high rates and costing them money.
Msi is more honest with their ddr5 listing. They separate their maximum speeds by dpc and 1r or 2r. Their z790 top end mobo lists:
Max. overclocking frequency:
Ã¢â‚¬Â¢ 1DPC 1R Max speed up to 7800+ MHz
Ã¢â‚¬Â¢ 1DPC 2R Max speed up to 6600+ MHz
Ã¢â‚¬Â¢ 2DPC 1R Max speed up to 6400+ MHz
Ã¢â‚¬Â¢ 2DPC 2R Max speed up to 5600+ MHz
Basically explaining that 2x8gb will be able to clock faster than 2x16gb, 4x8gb, or 4x16gb.
16gb ram is usually 2r, so 2x16gb is actually normal to clock up to 6600mhz stable.
Other manufacturers convienently leave out these details. So thank you msi for explaining the problem, and no thank you to gskill and asus for their deceptive bs that wasted my time and effort and forced me to research what was going wrong.
Maybe my next mobo will be msi.
It's a bunch of false marketing claims, then running and hiding or stony silence when users' builds fail. Thankfully returns are a thing.

Is there a reason this post neglects to mention the motherboard QVL, as itâ€™s unclear at this stage if you donâ€™t know it exists or are ignoring it. Itâ€™s designed to help avoid precisely what youâ€™re complaining about, also containing kit slot configuration. Can you also cite where overclocking is guaranteed [by any vendor]?
Lastly your assertions regarding ranks is incorrect. High speed kits above 7000MT are mostly SK Hynix a-die. These 16gb modules are single ranked.

You might try the test bios for your board here:
Itâ€™s a sticky in this forum. I am testing a Z790Extreme now and using XMP tweaked in the bios. This is a new XMP setting. Another person posted that they had to decrease their SAV to 1.15V for stability on a Z790Hero. I am still testing mine and I can say that decreasing the SAV to 1.15V has enhanced my stability as well on a different board. I am using a GSkill 7600 kit and just testing it for now. It may be worth your time to try the newest beta bios with some minor voltage tweaks.

I have the ROG Strix Z690-F Gaming Wifi motherboard with Kingston fury beast 16GB 6000MT/s CL40.
Out of the box X.M.P. didn't work for me either, I had to raise five voltages.
VDD - 1.41v
VDDQ - 1.41v
CPU System Agent voltage - 1.35v
Advanced Memory voltages:
IVR Transmitter VDDQ - 1.41v
Memory Controller - 1.35v
