Since there is no overclocking or XMP putting 1866 ram will not run 1866. You are being fooled by the Mhz Myth. Ram CAS latency counts a lot more than Mhz.
CAS 9 vs CAS11 or higher. You cannot use Quad Rank 32 gig memory modules and have it run.
This ram might work but I would check with the vendor about return if it doesnt.
1866 is a direct 16% boost against 1600. But it all depends on the controller sync with the CPU dye. You may not get a good boost even at O.C., even if memory bus throughput is boosted proportionally.

One point of RAM CAS counts around 2-5% at best.

Dell does not support overclocking, and 1600 is the highest speed intended for E5-26xx (v1) family.
All you can get is imroved reliability, like against overheating, or ionized radiation (if you are going to space, Fukushima Dai1, or Appalachians)
The story is different with V2-V4 series, but I guess it is not what you have on hands.
