jolphil Posted May 15, 2014 Share Posted May 15, 2014 (edited) Hello, I am running mint 13 LTS and with another hard drive Mint 16 as well as Ubuntu and Win7..All are on a individual hard drive via a removable HD rack..My CPU is an AMD 6 core 1090t with 4gb of memory.It should clock at 3200mhz. Ubuntu 12.04 reports lscpu as 3200.00 mhz clock ..Which is correct. My win7 with speecy reports same 3200mhz clock My Mint 13 LTS reports 800mhz as well as Mint 16 both reporting 800mhz for lscpu .. I also run on Mint less /proc/cpuinfo and it also reports 800mhz.. It shows 6 cores as in Ubuntu and Speecy Does anyone have any idea why the difference? Mint subjectively seems just as fast but I am puzzled by the difference.. Thanks for any information, jolphil Edit: I forgot to mention the BogoMIPS are also much lower in Mint:also correct mint 13 Edited May 16, 2014 by jolphil Quote Link to comment Share on other sites More sharing options...
amenditman Posted May 15, 2014 Share Posted May 15, 2014 Perhaps it is reporting the current use setting, not the available max. CPU stepping? 1 Quote Link to comment Share on other sites More sharing options...
securitybreach Posted May 16, 2014 Share Posted May 16, 2014 Yeah it sounds as though it is throttling the cpu up and down according to use (cpu frequency scaling). Look for the lines CPU max and CPU min in lscpu output. For instance, here is mine: comhack@Cerberus ~ % lscpuArchitecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 58 Model name: Intel® Core i5-3450S CPU @ 2.80GHz Stepping: 9 CPU MHz: 2521.750 CPU max MHz: 3500.0000 CPU min MHz: 1600.0000 BogoMIPS: 5587.56 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K Quote Link to comment Share on other sites More sharing options...

Maybe Mint has something like cpupower installed. Here is the link to the Arch wiki which gives more details on various ways to manage cpu power events. I also use cpu power tools in Windows but can not remember what the tools are called. If you are surfing the net you do not need a cpu to run at 3200Mhz it is just a waste of electric and you get unneeded heat and the noise. CPU MHz: 1800.000 CPU max MHz: 2900.0000 CPU min MHz: 1000.0000 As an example see the cpu usage above when I am running, asciiquarium,vlc,spacefm,firefox,xterm and xt7-player. This uses 1800Mhz and the cpu ramps up automatically. Edited May 16, 2014 by abarbarian Quote Link to comment Share on other sites More sharing options...
jolphil Posted May 16, 2014 Author Share Posted May 16, 2014 Ahhhh , Thanks guys, that makes a lot of sense. I will look into it further.. jolphil 1 Quote Link to comment Share on other sites More sharing options...
jolphil Posted May 16, 2014 Author Share Posted May 16, 2014 You are correct..I checked again on Mint13 and when the OS was first booted, lscpu reported 3200mhz and after it calmed down a bit, it later recorded 800 mhz.. The funny thing though, my lscpu shows NO Min Max cpu frequency as your example did..Oh Well Thanks again 1 Quote Link to comment Share on other sites More sharing options...
Cookie Posted May 18, 2014 Share Posted May 18, 2014 I have zero insight. Just wanted to throw out there that I had had problems with every version of Mint after 12. It's a shame too because I like mint. Having said that I still use 12. It is solid and sexy. Quote Link to comment Share on other sites More sharing options...
Capt.Crow Posted May 18, 2014 Share Posted May 18, 2014 Mint Petra went out with the bath water. Just as I had it up and running ......ouch! Quote Link to comment Share on other sites More sharing options...
jolphil Posted June 11, 2014 Author Share Posted June 11, 2014 Later update: I installed LM 17 on this machine..The install went well, but during the online update the machine did a hard freeze. They gave instructions after reboot how to issue a command to clear the dpkg install, and once that was done it did the update..Later on while browsing,another hard freeze.This prompted me to look at the propietary drivers for my graphics card.I used the nvidia suggested driver and since then my 17 has been rock stable. I must say this version is a lot like 16 but with LTS. The lscpu discussed above is exactly like the Mint 16 version.Happy Camper here,all my data and packages are running jolphil 1 Quote Link to comment Share on other sites More sharing options...
