I initially planned for a system with 128GB RAM because it’s a demanding 3D tool and everyday use—not just for gaming. Finding DDR5 kits that fit that size is tough right now, so you’re likely relying on two modules and hoping for the best. My setup succeeded but only at the base clock of 3600Mhz (limited by Ryzen/MC when using four sticks). After trying several DOCP profiles without success, I saw most manufacturers had just updated BIOS support for high-density RAM. So I swapped my 128GB units for a more affordable CORSAIR kit—192GB DDR5-5200 (four 48GB sticks). I used the DOCP1 profile and it worked perfectly: stable POST and solid performance at 5200Mhz! Check out the image here: https://imgur.com/a/RYnrpr6.

I installed this into a Ryzen 7950x with Precision Boost Overdrive enabled, paired with an ASUS ROG Crosshair Hero X670-E running BIOS 1003 (which supports HDRAM). The PNY RTX 4090 passed all four MemTest86 checks. Notably, I had to bump the RAM voltage from 1.25V to 1.26V to fix a recurring error on Test 8—though that was expected. Hope this helps!

I'm using the same RAM package with an ASUS ProArt X670, which has the latest BIOS (version 2007). Choosing DOCP1 is fine, but it still shows 4800 MT/s according to dmidecode on Linux. Memory details indicate a 48 GB DDR5 DIMM setup, no bank locator needed. If you want to reach 5200 MT/s, consider checking the BIOS settings or updating the firmware. You might also try adjusting the memory configuration or using different drivers.
