With RAM costing more than two kidneys these days, you probably want your kit to last as long as possible — and yes, running Buildzoid-level voltages daily will degrade your RAM over time.
XMP/EXPO profiles are usually overvolted on purpose, since they need to work across every CPU and motherboard combo out there. But if all you want is stock EXPO speeds, you don't actually need that much voltage most of the time.
Obviously this depends on your specific RAM and CPU combo, but the idea here is simple: run EXPO speeds, tighten the timings, push FCLK as high as it'll go, and use the lowest voltages that still hold stable.
VDD and VDDQ could probably go a little lower, but for the sake of stability — and not burning hours of my life chasing marginal gains — I left them at 1.4V, which is already plenty good.
Results: AIDA64 latency comes in at 60.4ns, and bandwidth is right where you'd expect for these settings (Read 70310 MB/s, Write 94549 MB/s, Copy 68099 MB/s).
