That's what I got (7950x steel legend), except that I'm running 128GB memory at 4800.

Here's my stream results (with the cpu in 105watt "eco" mode):

Interesting, didn't think memory speed will make so much difference but it did.

7950x X670E Steel Legend, standard mode, 2*32 GB = 64 GB RAM at 6000, CL 30.

    Array size = 1,000,0000

Wow, that's significant. I may have to look into that.
