SOLVED Turbo boost not working?

[vooze]

EDIT: Just tested it in Ubuntu and 2.8 GHz is working with Linux, so it should work here right?

Hi

I think I have everything up and running, but I can't get it to turbo boost (from 1.8GHz to 2.8 GHz)

I enabled powerd to make sure that was working (same result both with and without though)

The "problem" is that on 1.8 GHz it will only transcode 2 - max 3 Plex streams and I believe it should be able to do like 4 maybe according to passmark score.

When checking freq using SSH:

Code:

load 280%, current freq 1801 MHz ( 0), wanted freq 3602 MHz
load 531%, current freq 1801 MHz ( 0), wanted freq 3602 MHz

It should be on 2.8 GHz right? Am I missing something?

Specs:

- Fractal Design – Define Mini
- BeQuiet Pure Power L8 300W - 80 Plus Bronze
- Supermicro X10SLM-F (4xSATA3, 2xSATA2, 2xGigabit, 1xIPMI Remote management)
- Intel Xeon E3-1230L V3 (QC 1.8GHz, TDP 25W)
- Zalman FX100 passive CPU-Cooler
- 4 x Crucial 8GB PC3-12800 ECC 1600MHz (32GB total)
- Intel Quad netkort (4 x 1 Gigabit ethernet)
- 2 x 2TB WD RED (raid 1 - 2TB total - 2 x READ-speed, no write speed gain)
- 3 x 3TB WD RED (raid 5 - 6TB total - 2 x READ-speed, no write speed gain)
- 1 x Kingston SSDNow UV400 120GB SSD (For jails, etc.)
- 1 x USB 3.0 32GB stick for freenas-boot.

Please advice. I have been googling for days now.

Nothing special needed but you did get a CPU that is specifically limited in clock frequency. If you need performance you should have gotten a better cpu. What are your thermal temps? Are you sure the CPU isn't being throttled? Check BIOS settings? How are you verifying the frequency, are you sure it's reporting correctly?

Also 1.8 is the correct frequency for that CPU. Only 1 core at a time will turbo to 2.8GHz under the right conditions.

Is it too late to return the processor getting the low power version is usually not what you want to do. So CPUs use about the same watts at idle but low power CPUs are for environment where cooling is a problem.

Thank you for your reply.

As everything is working as intended it seems. Just talked to #freebsd on freenode, and it seems 1801 (0) means it's turbo boosting.

Also I bought the system used, so returning the CPU is not an option. But It's fine. I decided on a low power CPU for a reason (electric bill), so I will survive with 2-3 1080p streams :)

Guess my next system in 2-3 years will be more powerfull, but for now, this is all good. I got it all really cheap.

It's not that the "L" CPUs use less power, it's that they are capped at a certain power consumption so they won't melt when used in a laptop or an air-constricted server. Since it is going into turbo mode, and is fast enough, and you got it cheap, I'd say this calls for a Solved setting on this thread.

I'll reiterate your power bill will be exactly the same. All CPUs use about the same amount of power. Why is this so hard for people to understand. All the L processors do is limit performance and Max power.

Yeah, I'm trying to find the place to mark it solved :D

Also I guess the L cpu is not quite as powerfull as I thought. I just checked the passmark score and divided it by 2000, to get an estimate of plex transcoding power. But I guess 2 x 1080p streams and still some room left is all good.

I see. TIL ;)

Because they don't call them "power-limited" or "capped", they call them "low-power".

In this case, I don't think it's a big deal. Even limited, a 1230v3 is pretty powerful. With good cooling, the turbo mode is going to help, too.

Just tested it. Seems to max out at 3 x 1080p streams with a little room left. And since it's probably only gonna be 2 at max, 95% of the time just doing nothing, this is gonna be plenty powerfull. Also running at 800% CPU (8 threads) its still at 50 degrees C stable. (Did a test for 10 mins, temp did not go up) .

All in all. I'm happy :)
