Corsair DDR42400MHZ not certified but other speeds yes. Will it work?

[MountainKing]

Looking to buy one of those Asus boards locally,
https://www.asus.com/Motherboards/H110M-A/
https://www.asus.com/Motherboards/H110M-K/

They look like the exact same model...so no clue why different letters.
The RAM I am looking to buy is the Corsair Vengence 2X8GB kit reference CMK16GX4M2A2400C14 from here. (http://www.ebay.com/itm/Corsair-Ven...814773?hash=item3d30ec8ff5:g:fzUAAOSwA3dYf-uQ)

Memory speeds for this model is supported at 2133, 2666 and 2800MHZ on both boards. My question is will it work or should I look for another memory?

Differences : "A" board has HDMI out but no TPM header. "K" board has TPM header but no HDMI.

As for the memory, I thought all non "Z" 100 boards were locked to 2133MHz? From your links : "Due to Intel® chipset limitation, DDR4 2133 MHz and higher memory modules on XMP mode will run at the maximum transfer rate of DDR4 2133 Mhz."

You may still be able to adjust the CAS though, so instead of 2400 @ C14, you could get 2133 @ C13?

Oh thanks. So, if I got you correctly, the memory will run at a reduced speed of 2133MHz?

That's been my experience on an ASUS H110I-PLUS board. It ran at only 2133MHz (with 2400/C14 RAM) no matter what but I could still tweak the CAS down to 2133/C13. The difference was utterly negligible. It seems to be the H/B 200 series boards + Kaby Lake CPU's that run at 2400Mhz native. But just like previous gen Haswell's, the chipset refresh excludes the lowest end tier, ie, H110/B150/H170/Z170 -> B250/H270/Z270 (there is no "H210" just like there was no "H91"). The lowest end for "native" 2400Mhz on a non-Z board + Kaby Lake CPU = a B250. That vs a H110 though all depends on price.

I don't know whether a "2400MHz" Kaby Lake CPU on a non-Z Skylake motherboard flashed in advance to the latest compatible BIOS will run at 2133 or 2400. Likewise, you may not get 2400MHz if you stick a 2133MHz Skylake CPU into a 2400MHz 200 Kaby Lake board. Someone else with "Kaby on H110" or "Skylake on B250/H270" will have to test that.

Well what is weird is they gave other speeds compatibility. I don't think the RAM speed is going to matter much for me. I'm going with the cheapest option. As long as it will run, I'm OK with it. Thanks

I'm running a KBL G4600 on an H110 (ASRock DeskMini mini-STX) chipset, with GSKill DDR4-2400 SO-DIMM RAM (one stick), and CPU-Z shows my DRAM clock at 1200, which is DDR4-2400 speed.

I'm on the newest P1.50 BIOS, I believe, that shipped with this unit.

So it appears than even H110-chipset boards CAN use DDR4-2400 RAM @ 2400, WITH Kaby Lake CPUs.

Yeah . . . . that would be pretty vacant, to deny consumers of non-Z boards the ability to run RAM spec'd at XMP "OC" speeds and timings . . .

 

[MountainKing]

OK thanks guys. I'll be getting the Ram. Thanks

I am running G.Skill 2 x 8 GB DDR4 RAM on Intel B150 chipset based motherboard at 2400 MHz ( XMP 2.0 Profile set in Bios) just fine.
