ServeTheHome got up close and personal with Optane DC Persistent Memory in an article posted yesterday, removing the heat spreaders and taking a look at (and several photos of) the components within.

"We are going to take a 128GB Intel Optane Persistent Memory DDR4 module, and open it up. Until now, Intel Optane DC Persistent Memory has mostly been photographed with its big black heat spreader. We ended up with a handful of modules not from Intel, nor a system provider, but a handful to use."
Among their notes we have this interesting find, as SK.Hynix is the provider of the module's DRAM, rather than Micron:
"On the other side of the module from the Optane controller is a DDR4 DRAM module, this one from SK.Hynix. Model number H5AN4G8NAFR-TFC. We are not sure why Intel would not use a Micron module here since Micron has been the manufacturing partner for 3D XPoint thus far."
