It doesn't help as much in chips equipped with 3D V-Cache because the large amount of SRAM reduces those CPUs' sensitivity to finer adjustments. Moreover, EXPO ULL is not just a software-side solution — you need new RAM kits compatible with the tech to use this feature since the tweaks are baked into the memory's physical SPD. It's not something you can update like your motherboard BIOS.
Technically speaking, AMD is simply codifying what overclockers have done manually for years into an official certification. If you don't want to buy new memory to get the one-click profile, which is understandable in the current RAMpocalypse , you can just mimic the subtimings one-by-one. Of course, going at it manually comes at the cost of potential stability issues.

laxman10100 So I'll get a 4 nanosecond improvement in latency (according to the graphs, relative to what I already have with currently available DDR5) at the expense of a brand new, more than $800 memory kit that's 32GB (16GBx2) CL26 with ULL? I'm calling this ULL thing out as a whole hoopla of bs-ery. All whilst the thoughts inside the minds of Hyn, Sam and Mic all being something along the lines of creating a somewhat believable reason for as to why the RAM prices are staying as high as they'll be staying for another 3-4 years. Meanwhile, there probably won't be any real significant changes in that time. If we're lucky, maybe we'll get some 6000CL24 kits with ULL in another few years. That would be a more significant change. Reply
