You're just beyond unlucky. I bought that exact same board over three weeks ago but got sent the regular ATX lightning and even that was able to stable 7600Mhz. 7800Mhz and upward is too much for this 4 dimm lightning. This is also with latest 7.01 bios, unfortunately I sold my 32Gb kit earlier today but it was the same, no booting issues whatsoever on both these kits with fast boot disabled.. As soon as I get ITX lightning replacement from importer (out of stock from whole country) I'll film you stable 8000+ reboot montage . I don't even have any holy grail 14900K - not even top 10% according asrock cpu indicator in bios.
I hear ya. The frustration is not that it takes long or that it fails, it first boots and is stable than the next day it is not and it doesn't even wanna boot anymore. As soon as you leave the JEDEC spec you're or were screwed and all the rules of timings disappear. Those 8600MHz and up boys, cudo's to you but that is mostly silicon lottery. They also buy 24gb high speed ram otherwise its not possible to run 8600 on my sticks which are rated for 7200. 7800-8000 is the max for these sticks i think in general.
@@meppie1922 Yeah 8600Mhz is not gonna work with A-die, even 8400Mhz is really hard with A-die. I mean really able to stabilize it with all stress tests. But 8000-8200Mhz is really minimal effort job if your cpu can handle it. I've had multiple A-die kits and every single one of them, ranging from 6000-7200Mhz A-die XMP kits were able to stabilize those with slightly differing timings, but in the end performance difference was negligible. All this on Z790 Apex Encore and I believe that lightning is better board what I've read. If you want to try. 1. Load UEFI defaults 2. Fast boot off 3. Primaries for 7600Mhz 36-46-46-121 1.40V VDD/Q *OR* Primaries for 7800Mhz 36-46-46-125 1.45V VDD/Q (I'd try stable 7600 first) 4. Set SDRAM Die Density to 16Gb 4. Reboot 5. In case it wont boot or TM5 errors early, start lowering TX in 0.010mV steps until you boot. Everything else on auto, do not freestyle any other settings until you can boot and pass TM5 consistently.
