Does this mobo support 32GB DIMMS?

https://www.supermicro.com/products/motherboard/QPI/5500/X8DTL-i.cfm

on the page, supported DIMM sizes were 1,2,4,8,16 GB

I'm wondering if it supports 32GB DDR3L-1333 ECC DIMMs

specifically part no. HMT84GR7BMR4A-H9

i am wondering because it may be because the mobo was released before 32GB Dimms were sold

such was the case with my Rampage 3 Extreme where i could install 8GB dimms despite the website saying max 4gb dimms were allowed.

If I remember correctly, 32GB LRDIMMs are sketchy on this platform. I think they're meant more for the later socket 2011 Xeon E5 chips.

I can confirm 16GB DIMMs work perfectly.

I wouldn't do it. Stick to 16GB modules. I run 6 of those in a DL380 G7 rackserver based on the same platform and that runs like a charm. Even if they end up working, you might only be able to run those 32GB modules at 800MHz.
