Why is my T8300 running at half speed ALL the time? Plz help!

Hi guys! I was doing some testing with wprime just to see what scores I could get with my R61. Now, I always got 70 sec and that seemed quite low for my computer. I thought it was just one of those Vista quirks but then I checked it upp with zpu-z and got this result:




Well, thought I, it´s probably just "speedstepping" so I put the energy manager in performance mode and started up a movie and a mp3 file to put the cpu under some stress. Guess what? Still same, half speed! So I tried wprime again to really stress it but still...same...speed. So please can somebody tell me what´s wrong, I didn´t buy a laptop with core2duo to get a crippled dualcore.

 

Download RMClock, actually check the Undervolting Guide, that can help you. You can control multipliers through RMClock and see if anything is stopping it from clocking up.

ALSO

Check your temps, if it is getting too hot it will not clock higher to protect itself from danger of burning out. Download HW Monitor for temps.

 

Thanks for the input but isn't strange though. that it isn't set at 2,4GHz/default? Why should I have to do all this work to make it run at advertised speed, doesn't make sense to me.

 

check windows mobile settings. in the options look for the processor max state and minimum state. make sure both are set to 100%

 

I checked everything, everything is at 100% both min and max. Plus I turned of all energy savings settings AND speedstepping in the BIOS, still its at 1,2GHz, now it's really starting to get to me. Guess I have to download that RMclock thingie, I don't like having to tamper with that kind of stuff....

 

No real damage can be done, as long as you dont raise the voltage higher than stock.

Temps?

 

These are the temps right after a wprime test:


When idlle it usually stays around 38C/90F with ALL powersave settings turned of both in windows and the bios.

 

Ugh! I don't have the energy for this. Next time I'll buy a single core netbook or something. At least I'll know what I'll be getting, seriously I feel ripped off. If it walks like a duck, looks like duck and quacks like a duck...it's a duck even if it's making itself out to be @ 2,4GHz.

 

Weird, maybe the CPU isnt seated properly. I would send it back, is it covered under warranty still?

 

I was thinking the same thing, returning it that is. Fortunatly I have a 3-year warranty and I bought it this year so, back it goes!

 

I know that disabling Speedstep on Dell laptops locks the processor to the lowest multiplier. This might be the case as well for Lenovo; have you tried leaving it enabled and trying your tests?

Well, that's a bit hasty without figuring out the cause. Shotgunning the problem may leave you back where you began: confused.

 

Make sure you are running in balanced energy mode not power save, then run wprime and while it is running check cpu-z and see what frequency you get.

If it`s not 2400.0 MHz or just under something is wrong.

 

As rflcptr said, disabling SpeedStep in most cases just locks it to the lowest multiplier, and I assume Lenovo is no exception here. Make sure you reenable it.

Once you have SpeedStep back on, download and run RMClock, and try disabling all multipliers except the highest.

 

Something's wrong with your BIOS Settings, or with Speedstep. Check my T8100 scores:


I'd love to have that T8300 of yours if you don't want it

 

Thanks for all your replies! I posted same topic at lenovo forums and the tech guys there told me to insert the battery and guess what? full throttle with battery/ac combo. Isn't that weird? with AC only it should be at full speed. Anywho, I also reinstalled lenovo power manager and put it in "thinkpad default mode" and did a wprime test -without the battery inserted- an the CPU went full speed. I guess everything is working as it should so...t30power: you may NOT have my T8300

 

no the CPU is fine, this is a known issue with Lenovo hardware. You are likely running off your 65WATT ac adapter that was shipped with the computer, but on rare occasion that 65watts isn't enough to power the computer so it needs to have the battery as a buffer. with out the buffer the computer makes sure it won't hit >65watt consumption and throttles the processor.
My T500 does the same thing.

So yah, to Quote Lenovo "Your computer is working as designed".

 

I dont recall you telling us you didnt have the battery in..thats a pretty crucial piece of info.

 

If you switch off SpeedStep in BIOS, it forces the processor to the minimum multiplier (6.0x in your case) until you enable it again. At least that's what happened with my ancient Pentium M - 2.0 GHz to 600 MHz .
