I only get errors when 4 sticks are running

[thisguy12345]

Hundreds of errors on tests 4/5/6/7 when all 4 sticks are in (4 x 16gb). All sticks from the same batch, but two different packs ie their last 3 digits are 499, 501, 515, 516.

Ram is Corsair 32GB (2x16GB) CMK32GX5M2A4800C40 Vengeance C40 UDIMM 4800MHz DDR5 DRAM

Msi pro z690 a wifi (ddr5)

i7-12700k
