Will UDIMM work with B350m motherboard if it says DIMM?

Solution
UDIMM is Unregistered DIMM; i.e., standard memory. They are on the published list found here: http://www.anandtech.com/show/11624/patriot-publishes-list-of-amd-ryzen-compatible-dimms-up-to-ddr43400-up-to-64-gb Contact Patriot and ask them if that kit will run at its rated speed on the MSI B350M PRO-VDH motherboard. If you want a Patriot kit, then why not buy one on the MSI list? https://www.msi.com/Motherboard/support/B350M-PRO-VDH.html#support-mem-2 (Compatibility, Memory Support Ryzen Series). Personally I'd consider a kit like the Patriot PVE416G300C6KBL that has been tested with 4 modules; then you know that 2 modules shouldn't an issue.

If it's not compatible, does that mean that it will work, but the clock speeds can't be OC and quad Handel won't work? Should I just pick ram that is on the list?
