Intel Turbo Boost 2.0

Jayge91 · Feb 28, 2020

I'm sure this question has been asked several times, but in my searching I've found nothing pointing me toward a useful answer. Hopefully someone can help me.

I have a Xeon 1270 v6 (3.8GHz - 4.2GHz max boost) that seems to be locked at 3.8GHz in FreeNAS, and would like to find a way to unlock the performance I paid for.

Setup:

Code:

Intel Zeon E3-1270 v6
SuperMicro X11SSL-F Motherboard
NEXMIX DDR4-2400 32GB (2x16) ECC Unbuffered RAM
2x LSI SAS JBOD cards

Here's the output of sysctl -a | grep -i cpu:

I would expect the dev.cpu.xx.freq_levels to show 4200/(something), but maybe I'm just boned?

These two lines right here are what you need to check:

Code:

dev.cpu.0.freq_levels: 3801/72000 3800/72000 3600/66145 3400/61191 3200/56425 29           00/49260 2700/44929 2500/40138 2300/36144 2100/32318 1900/28643 1700/24566 1400/           19331 1200/16209 1000/13237 800/10403
dev.cpu.0.freq: 3801

The way Turbo Boost works as far as the cpufreq displayed in Linux/BSD is that it's shown as the max rated +1, in your case 3801. The actual turbo bin that it's running on isn't reflected accurately by cpufreq.

But since you see 3801, it means you're turboing just fine.

So I should basically forget about being able to raise that to the advertised 4.2?

The relatively meaningless number indicated by cpufreq? Yes. As long as it says that it is running at "3801MHz" that indicates that turbo is working.
