Question Memory limits of certain CPUs. i5-6500, only supports DDR4-2133 on a stock chipset? Whazzat? i5-7400 only supports DDR4-2400? i3-8100?

Interestingly, the i3-8100 only supports DDR4-2400, and not 2133/2400 like the i5-7400. Does that mean that the i3-8100 won't run with stock JEDEC RAM?

I've been SOOOO spoiled by AM4. Even my A320 mobos can push DDR4-3200 RAM with my Athlon 3000G 2C/4T APUs...

This is in relation to memory upgrades for the rig(s) I picked up as mentioned in this Pre-built thread:

Another OEM gaming PC conversion, HP ProDesk 400 G3 Micro-Tower (i5-6500, 8GB DDR4) off of ebay. (Now TOTAL CONVERSION!)

I purchased a few "HP ProDesk 400 G3 Intel Core i5-6500 @ 3.20GHz 8GB RAM 1TB HDD Mid Tower" off of ebay at a good price. (Hint: "Make Offer") I also already picked up some GTX 1650 D5 refurb cards for $120-130 @ Newegg a few weeks back. So, as-is, I could build these into "Gaming PCs", likely...

Anyways, can I just chuck in a set of 2x8GB DDR4-3200 Team Group Vulcan Z memory, and hope that it runs OK (if complete overkill) with the i5-6500 CPU, on an H110 chipset? That's what I picked up, a bunch of kits for under $60 ea., it's not much of a "loss" to run them at 2133, they were (relatively-speaking), "Cheap enough". If anything, 2133 RAM these days carries a price premium, since it's now so unusual (outside of surplus sticks gleaned from OEM rigs like these).

If you use XMP-based RAM kits, you'll get the JEDEC timings programmed into the DIMMs which will normally give you DDR4-2133. You can try reprogramming the SPD timings but good luck with that. Granted you are dealing with OEM boxes here so actual behavior is not . . . guaranteed.

Yeah, guess I'll know at the beginning of next week sometime. Also whether or not the mobo includes a working NVMe slot, and/or needs a BIOS update to use it with Win10.
