Bios issue 99%
Try loosen the timings

 

Gigabyte Z690 motherboards are known to suck hard right now. Swap for ASUS/MSI and save yourself the trouble.

 

I also think it is a bios issue...early days for DDR5, XMP and bios...check this post

 

That's what I figured sadly. Got the MB and Ram combo on newegg as part of a bundle, so can't return either individually. I'll wait to see what the future holds, and may eventually jump to Asus. Thanks everyone!

 

I ordered that same RAM kit yesterday from Newegg as a combo with an Asus ROG Strix Z690-F Gaming motherboard. It’s not due to arrive until next week, but I’m concerned the RAM speed may be too high even for this board. However, I already purchased a Gigabyte Z690 Aorus Master from Micro Center last month, and that’s the board I’d prefer to keep and use. I’m tempted to try the RAM with both boards to see how it runs, but I’ll be extremely disappointed if the XMP profile can’t even be used.

Out of curiosity, did you update your motherboard BIOS? I know Gigabyte Z690 DDR4 boards are having a hell of a time with RAM speeds above 3200. There was a BIOS update for my Aorus Elite AX DDR4 board, and that corrected a BSOD issue I was having but not the inability to go beyond 3200 without game crashes and WHEA errors.

 

If the RAM is on the Motherboard QVL list , just take it back for RMA and get another board.
That seems to be thing everybody is doing with Apex boards

 

Same here 12700/2x16gb adata xpg lancer ddr5 5200/asus strix z690 e gaming,with one 1x16gb stick xmp is working but with two 2x16gb sticks non of xmp works on any asus bios,can someone explain how to manually set freq. do i just need to set 1:1 and freq to 5200mhz or i need to set freq. to 2600mhz? and is there aditinal steps with voltage ? if its to complicated i guess ill stick to 4800mhz then
