CPU-Z reporting P8600 speed as (6 x 266 = 1.6ghz) under 100% load. Speedstep disabled in Bios.

System Specs

Lenovo X200

Intel P8600 2.4ghz (266fsb x 9)

4gb ram

Bios 1.05 (most recent is Bios 1.07)

 

CPU-Z (v1.48) is reporting my CPU speed to be 6 x 266mhz = 1.6gh. i have disabled speedstep and have maximized every power performance option i can find in power manager and still dont see the multiplier jump to 9x even under 100 % FULL load (with OCCT & P95).

 

Is CPU-Z reading the speed wrong? (OCCT reads it wrong also @ 266 x 6)

Or is there some bigger problem with the X200?

Not sure what Laptop you have, but maybe it applies to all.

 

Do you have Lenovo Power Management installed?  If so, switch it to Maximum Performance.  If you use Windows default software, then make sure that is at maximum.  If you're using Intel's SpeedStep set it to "Fixed".  Use software like Intel TAT to set both Cores at full load (this gives core speed and temp).  Or Prime95 works too.

 

Update BIOS to the latest of course.  If you still have problems your next best bet is to reformat and see if the problems is still there.  Worst case senerio send it back to Lenovo.

Please try Everest to measure your frequency.

I have the same problem with my X200!

 

System Specs

Intel P8400 2.26Ghz

2GB Ram

Win XP Pro

Bios 1.05

 

I measured with Everest Ultimate Trial: the CPU never goes above the 1.6Ghz (6x266).

In low power settings it goes down to ~800Mhz (6x133) - CPUz didn't notice that by the way

 

I have installed the Lenovo Power Management driver and tool and set everything to maximum but it still doesn't go above the 1.6Ghz

 

 

--- Edit ---

 

Problem solved!

 

I took the risk and flashed the BIOS from 1.05 to 1.07 in Windows.

Now the CPU clocks up to 8.5 x 266 = 2,26GHz (correctly shown in Everest and CPUz 1.48)

 

Greetings

Frosac

I went to the Lenovo support site and looked up the drivers and software page for the X200.

 

--> http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-70476

 

The first entry is the BIOS

 

I downloaded the 6duj04us.exe file and flashed as it is described in the installation instructions at the bottom of the page

 

Note: I flashed in Windows with just my  Anti Virus program turned off. It may be safer to flash in Windows Safe Mode but in the installation instructions I couldn't find a word about this. Therefore I'm not 100% sure that it will work in Safe Mode. However I would not flash in Windows if I'm not sure thats it's running absolutely stable.

 

Good Luck

Frosac

Hello,

 

I would suggest to flash from a bootable cd. It´s the safest method.

Burn this file to disc and boot with it.

There really is no real "safe" way to flash a BIOS.  The only things you can do to be sure it doesn't screw up is, keep your laptop plugged in, and be sure the Battery is at least 75%.  Using the software provided by Lenovo is the best way to flash the motherboard's BIOS.
