WEI Processor dropping to 5,5(

hi everyone,
my WEI processor rating most recently from 7.1 to 5.5 and I have no idea why.. I decided to run the WEI rating again as online videos started to become laggy and cpu usage was up to 100%.. battery and ac are plugged in and energy setting are set to maximum performance of course..

please advise

 

Sounds like the throttling situation some are dealing with. What are your power settings on? Maximum Performance hopefully?

 

Turn off the laptop completely (don't just restart), make sure both the battery and AC adapter are in. Verify the laptop isn't hot and then turn the laptop back on. Run the test again.

 

done.. still 5,5 :-(

 

Perhaps download hwinfo32, run it, and tell us what speed (MHz) your CPU cores are running at?

Petrov.

 

Did you also make sure to set your profile to maximum performance?

 

Ran it on default settings:

yep..

 

A Core i7-2620M has 2 cores and 4 threads. HWiNFO32 is only showing one core so it looks like you have half of your CPU disabled.

When you ran ThrottleStop, did it show 4 threads in the table on the right hand side or only 2? You can also run CPU-Z and at the bottom it will tell you how many cores and threads it is seeing.

The usual fix for this problem is to go into msconfig, click on the Boot tab, Advanced Options and make sure the Number of processors is NOT checked. After you do this reboot and make sure these programs can find all your threads. The Windows Task Manager should also show 4 separate graphs for your CPU.

Once you get that solved then you will have to have a look at whether Turbo Boost is working or not. In the log file you sent me the maximum multiplier I saw was 27.00 which is the default multiplier for your CPU.

Post a screen shot of ThrottleStop while running a single thread of Prime95 or Super PI Mod 1.5 so I can see if Turbo Boost is working or not.

Also click on the ThrottleStop TPL button and TRL button and post a screen shot of what is hiding in those windows.

For a Core i7-2620M the maximum turbo boost frequency when 1 core is active is 3400 MHz and when both cores are active the maximum is 3200 MHz. Your CPU is only running at the default speed of 2700 MHz.

 

That was the issue! Thanks alot!

 

Not sure if I got this right but after I opened Super PI Mod I assigned only 1 processor to the process.. please see below:

 

That test is perfect, just what I was looking to see.

The log file you sent me was showing nothing higher than the default 27.00 multiplier but your screen shot shows that you are getting full turbo boost.

Your CPU is designed to use the 34 multiplier when 1 core is active and to drop down to 32 when 2 cores are active.

When you use Set Affinity... and force a task to run on only one core, there are still lots of Windows background tasks that need to be processed. These wake up the second core on a regular basis which drops the maximum turbo multiplier down to 32. When the background task is taken care of, the second core goes back to sleep and the multiplier jumps back up to 34. This transitioning back and forth between 34 and 32 is going on hundreds of times a second. ThrottleStop uses high precision timers within the CPU and reports a very accurate average multiplier during each monitoring period. Because of background tasks waking up the second core, it's impossible to ever see the full 34.0 multiplier for any length of time.

An average multiplier of 33.71 shows that it was using the 34 multiplier 85% of the time and the 32 multiplier the other 15% of the time. That's typical. If you could minimize the number of background tasks running you might be able to keep the second core asleep for a longer period of time and average slightly more than that.

The Package Power Limit shows the Intel turbo default of 35 watts, 97 amps for your CPU. The bios has enabled those limits and locked those settings so there is nothing you can adjust to get higher performance.

Your CPU shows 4 threads and is running as designed. Thanks for sharing your results.

 

Thanks for that explanation
