You can never have too much memory

The problem is that I have as many as 30 of them. And none of them will boot, even with just a single stick installed. Last time, I managed to convince the client to swap the memory, but that’s not an option now due to current memory prices. What advice can you give, and is there actually a solution to this issue?

Intel Core Ultra 5 250K Plus, 4.2GHz, LGA1851, 18 cores, SVGA, OEM
Gigabyte B860M DS3H, LGA1851, (HDMI, 2xDP), 4xDDR V, mATX
32Gb Patriot Viper Venom Black PVV532G640C32K, DDR V, PC-51200, 6400MHz, kit 2x16Gb х2

P.S. I’ve tested almost all Core Ultra processors with this configuration, as well as every BIOS version available on the motherboard manufacturer's website. It works fine with other RAM—for instance, Samsung DDR5 CUDIMM 8GB sticks work in any quantity; I even tried Kingston and the legendary KingSpec, and they worked—but the Patriot ones just won't.
