fwiw, most DDR3 ECC UDIMMs will work fine in non-ECC mode if ECC isn't supported. But still, if they don't want them because of this, I can actually use them as I'm needing a pair in an older system that does support ECC UDIMMs.I can do that, just pay shipping. Let's switch to a PM. For context the RAM is ECC UDIMM so not sure if that will work for your project.
