Hi,

I'm interested in buying the X99E-ITX/ac motherboard. It is stated on the specifications page ( http://www.asrock.com/mb/Intel/X99E-ITXac/?cat=Specifications" rel="nofollow - http://www.asrock.com/mb/Intel/X99E-ITXac/?cat=Specifications ) that the MB supports up to 32GB of memory only, even with Xeon E5 processors which can in principal handle 32GB and 64GB modules. Would the MB run with a pair of 32GB LRDIMM modules?

Thank you in advance.

Greetings, this is ASRock Technical Support Department.

We have tested the X99E-ITX/ac can supports LRDIMM 32GB *2 with Xeon series CPU with BIOS P1.12G.

This BIOS will be uploaded to website soon.

If any, please feel free to contact us.

Kindest Regards,

Just to be clear, did you mean the LRDIMMs currently on market, the relatively new Samsung 32GB RDIMMs that just came out on market, or both?

Well, I was talking about 32GB registered modules in general. However, it would be useful to know if the MB is compatible with https://www.ramcity.com.au/buy/samsung-32gb-2x-16gb-kit-pc4-17000-ecc-load-reduce/2xM386A4G40DM0-CPB" rel="nofollow - these LRDIMMs from Samsung in particular.

Which is why I asked, the reply that ASRock gave seemed to be referring to LRDIMMs specifically Confused

It's very likely that I'm gonna be satisfied with a couple of 16GB modules, the 32GB ones are rather expensive. Besides, there are hardly any non-server workloads which can benefit from having more than 32GB of RAM in the system.

I've just ordered the http://ark.intel.com/products/81905/Intel-Xeon-Processor-E5-2658-v3-30M-Cache-2_20-GHz" rel="nofollow - Xeon E5-2658 v3 CPU. Not for the full price of course, I'm just a mortal guy. Our Chinese friends had a very attractive offer...
