Faulty CPU-Z readings?

post #1 of 10
Thread Starter 
Hey, i've recently tried overclocking a bit, but i failed and abandoned the project

Now i just, out of curiosity downloaded CPU-Z for my laptop, which is an Acer Aspire 5530... The readings are all random. Sometimes the multiplier is 10x other times 5x and I even caught it as low as 2.5 muliplier. Why does it change so?

10x multi.

5x multi


I couldn't seem to encouter the 2.5 multi anymore... Wierd

EDIT: Pictures doesn't work, here they are (think they'll work...)

If its a laptop it will most likely be throttling the CPU, ie turning the speed down when its not needed to save power.

It's because your CPU has powersaving features built in that throttle down your CPU when not under considerable load. Fire up Prime95 and unless you're overheating, you'll see it'll stay at the highest multi.

This is a good thing That your laptop slowing down the CPU when there's nothing much happening to save your battery and make it last longer

When your doing something more intensive like watching a youtube video etc, it will ramp back up.

If you want to stop this from happening. Go to the power option in control panel and change from Balanced or Battery Saving to High Performance, but this will have a major impact on your battery life if it's not chargeing.

Hope this helps

Check in the BIOS for the power saving feature's if you want to disable them

Don't disable C&Q.
Edit high performance plan processor power management cause high performance plan scales CPU multiplier due to minimum processor state set at 5%.
Hint* bump CPU min to 100% on power. Leave it @5% on battery though.

Its throttling the cpu for power and heat etc. Leave it enabled unless you want a hot lap and a dead batt quick. Its smart enough to realize when to ramp up or down.
