11600K, 32GB 3200Mhz (2x 16GB) advice

[modd1uk]

Hello folks I'm after a bit of advise, never too proud to ask for help.

I've got an 11600K here that will run 2x 8GB 3200MHz fine, memtest 0 issues, boot to windows and work perfectly.

I got a good deal on a 32GB kit of the same RAM but 2x 16GB @ 3200Mhz.

PC boots / passes memtest with 1x 16GB 3200MHz DIMM in running at 3200Mhz but won't post at 3200MHz with both sticks in.

The other stick is the same, boots fine @ 3200MHz, its just if you fit both 16GB DIMMS it refuses to post at 3200MHz...but will work fine @ JDEC of 2400MHz.

Answers on a post card please folks, the RAM is on the QVL list for the board, its a B560 Tomahawk WiFi & i5 11600K.


Thanksssss

Already on the latest BIOS that was the first thing I did. It seems it'll do it in Gear 2 but not Gear 1, common with the 11th Gen i5's apparently.
