I recently made the switch from intel with the 9800x3D. I am loving it and diving face first into optimization. During my optimization journey I have noticed the first core never is used except for about 30 seconds after first turning on my pc.
This is what my process lasso looks like when my computer is more or less idle.

I recently followed the steps to enable the 3d v cache as discribed by Jayz' video about the 7950x3D but none of this applies as I've found out due to the redesign of the 9800. I have tried updating everything in windows, all my drivers including my chipset drivers, updated my bios. So far I havent seen any other fixes for this problem. I have tried "forcing" games and other applications onto just the 1st core but all that ends up doing is freezing whatever I put on the core and the 1st core remains completely dormant. Is there anything else I can try? Is there something wrong with the cpu I got potentially?
