Discussing XMP settings and reducing CPU speed for DDR4-3000 performance
Hello Community, Haven't built a PC in quite some time. Recently updated my six year old rig with the following items: - Intel i7-5820K (Haswell-E) - Corsair Vengeance LPX DDR4-3000 16GB (4x4) - ASRock X99 Extreme4 2011-V3 I'm new to XMP profiles. I noticed that the memory was running at 2133Mhz and read that this was the normal stock speed for the memory/X99 setup and that I needed to load the correct XMP profile for it. Link: There is only one XMP profile for DDR4-3000 and when I select it everything works great. However, loading this XMP profile lowers my CPU speed to 2250 which isn't a lot, but it's lowering my Valley benchmark by about 200 points. DDR4-3000 is stable, but I notice absolutely no difference in performance. I'm irritated that I see no performance change, but my benchmarks are dropping because the XMP lowers the CPU speed. My question - How can I get this board to run DDR4-3000 and not affect the CPU/Gaming performance?

Do you have the most recent BIOS and mobo drivers? The DRAM should operate independently, running at 3000 shouldn't impact CPU speed, which suggests you might be using ASRock software or similar tools that can produce unexpected outcomes.

Tradesman, things are becoming clearer for this gentleman.
In my last two memory buys over ten years ago, adjusting the right settings made the speed readings accurate. This configuration was unfamiliar to me—2133 as the base speed, buying memory meant it should run smoothly at 3000Mhz but needed a boost.
I adjusted the voltage to 1.35, fine-tuned the timings to 15-17-17-35, and reduced the BLCK setting to 125, which slowed down the CPU. Then I modified the CPU tweaks, setting it to DDR4-3000 at 3.5Ghz.
