Question Gigabyte X99-UD3P not working with 3200mhz ram, even when manually specified in BIOS

[Dead_Pixel_97]

I've been running the following for a while

Gigabyte X99-UD3P
Intel Core i7-6800k
Crucial Ballistix 4x4GB 2400MHz Model BLS4G4D240FSCM8FADGM
GeForce RTX 2070 Super

and recently decided to upgrade my ram - initially I was only going to upgrade the amount (from 4x4GB to 4x8GB), but decided I might as well upgrade the speed as well.

Got around to looking, found out the motherboard supports up to 3200MHz, so I ordered this
https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232886?Item=N82E16820232886

and to my surprise, it did not work. Just kept power cycling, no post, no post code beeps. Tried with 1 stick, 2 sticks, and all 4 sticks. Tried manually setting the Memory clock speed in the BIOS, nothing. reset CMOS, nothing.

So I went to the motherboard RAM support list & found this listed as compatible RAM
https://www.amazon.com/gp/product/B015FXXBW0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Which has the same spec as the previous RAM, as far as I can tell. So I ordered it & tried it. again no luck. same as before, tried 1 stick, tried 2 sticks, reset CMOS. same as before it just power cycles.

So I upgraded the BIOS to the most recent version. nothing.

What am I doing wrong?

I feel dumb. Immediately after posting this, I tried the first set of RAM again (now with the new upgraded bios) and it worked. but the "supported" RAM still did not so idk what's up with my machine.
