No DSD512 Sound with my iDSD micro

I have the same DAC. You need a lot of CPU to get DSD512. My i5 Mini can’t do it and neither could a dual Xeon.

DSD512 - Is this even possible? [yes, just needs more cpu]

I run Roon Server on a 8 core/16 thread Xeon machine. The clock is 2.6Ghz. It has 16GB of RAM. I have never successfully upsampled to DSD512, although I have a couple DACs capable of that res. I am thinking that clock speed, rather than number of cores, is the limiting factor. Is this true? I upsample to DSD256 without any problems. Is DSD512 more than just theoretically possible? Is so, some recommendations on capable machines, please. Thanks.
