ASRock surprisingly hasn't responded to me for days. But fear not! Blue Fox on this HF thread came to the rescue:

Xandr / alfaSZ: I've got the same issue with those corsairs and have been waiting for asrock support to get back to me for some time. Is it possible to point me to the download link for the L1.35 BIOS or just send it to me directly? I was able to borrow a *GB DIMM from a friend to POST the MB but am running out of time before I have to give it back.

Thanks!

Yeah, I was sent the L1.35 as well. Glad to hear that it works for you, alfaSZ.

I'm still waiting for the single 4gb module I ordered so I can actually flash the BIOS. :S

Great! I'm not surprised that happened. If a quick fix can be done, ASRock can provide a custom BIOS version in some cases.

A quick update here - I have been sent a pre-release version of uefi 1.35 that resolves the memory incompatibility and so far works fine

The situation, or reality currently, is ASRock and other mother board manufactures are dealing with the release of Skylake processor boards. Add to that the release of Windows 10, and they are all rather busy right now.

I have a new ASRock X99 Extreme6/3.1 board, and its UEFI/BIOS could use some work too IMO. Exactly when we'll get some updates, I truly do not know. You can always submit a support request using this page and form:

I'm using the 4GB Crucial 2133 memory, a 4 x 4GB kit. That works fine in my X99 board, and can even be over clocked to 2666 easily, using the timings for 2133.

@parsec: I wasn't referring to the spec of 32GB max being an oversight, but not having any 16GB modules listed as being compatible. I'm well aware of the fact that these are still quite rare, but there are modules, like the Kingston KVR21R15D4/16, which have been confirmed working with the X99E-ITX/ac. So it seems strange to me that ASRock has decided to not test any of the available 16GB modules, because not having any listed as compatible to me means that they haven't tested any.

@alfaSZ: Have you tried the P1.20E? As far as I know, that one only improves NVMe compatibility for certain M.2 SSDs as well as the M.2 to U.2 adapters, but you never know. I won't be able to do it myself since no store here in Cork, Ireland has any DDR4 modules in stock and I would have to order them online first.

I'm sure at some point UEFI/BIOS updates will be available to allow the use of 16GB DIMMs on the X99E-ITX/ac and other ASRock X99 boards.

The specification of 32GB maximum memory capacity on the X99E-ITX/ac is not an oversight due to the capacity of the DIMMs available. The maximum memory capability is based upon the board's use of two memory channels with only one slot per channel, and the maximum memory spec of the I7-5000 series processors, which is 64GB. Remove two memory channels of the four, leaves 32GB.
