[qubes-users] Qubes 4.0 with Intel(R) Core(TM) i7-8700T CPU @ 2.40GHz

Am running 4.0, fully patched, with a CPU capable of 2.4GHz, but Qubes reports 800MHz.

xentop - 10:57:04 Xen 4.8.5-36.fc25
10 domains: 1 running, 9 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown
Mem: 33345840k total, 28558708k used, 4787132k free CPUs: 6 @ 792MHz

How can I diagnose the issue, and see full utilization of the CPU? I don’t see this on other PC’s with different CPU’s, just this one with an Intel(R) Core™ i7-8700T CPU @ 2.40GHz.

Thanks,

Found the issue, it’s a feature of the Dell Optiplex 7060 when power is low. Re-seating the power adapter resolver the issue. Not a Qubes or Xen issue.

I had never looked at it before, but I'm getting "CPUs: 4 @ 3997MHz" :wink:
