Ummm? CPU-Z

[The Last MeMe]

So ive posted about this laptop before already can be found here: http://linustechtips.com/main/topic/36566-laptop-problem/#entry475866

 

 

Anyways once I had some time I sat down and downloaded cpu-z onto the laptop (which I have never used before ive always used speedfan) and I noticed the core speed will drop down to 750mhz and jump back to 2.5ghz quite often which ive never read about happening to anybody on these forums but I am not sure if this is normal since I have never used this application before.

It's normal that it jumps up and down all the time (whenever it's being used/not used) unless you disable all adaptive and power saving features of the cpu.

 

Or set the PC to do folding or something in the background :p

Okay we'll was just making sure It wasn't throttling, guess it must be the HD?

It is throttling, but not because of heat. It's because of the CPU power saving technologies, not the hard drive or heat.

Like above poster said it is throttling, but in a good way. Has nothing to do with the HDD. It's just throttles up and down depending on usage.

 

Start some test program, run a lot of flash based browser windows or whatever to put some stress on the system and the CPU will stay at a high clock and work.

 

SInce it's laptop it might end up throttling down due to heat, but you won't know that unless running some stress test or games while monitoring temperatures.

Well if you read my other thread I've been having issues with it being very slow so if this throttle is Normal then it must be the HDD making the noise etc..

[Godlygamer23]

What kind of noise?

[The Last MeMe]

A weird grinding sound, read the thread I linked to to read more.

[Godlygamer23]

Try checking the hard drive for any kind of bad sectors.

Weird noise from the HDD is bad, that said a normal HDD does make noise while working and different brand HDDs sounds slightly different. If you're not used to HDD noise it can be difficult to know if it's a healthy or unhealthy noise. I've got no idea how experienced you are with different hardware or if you've experienced HDD failure before and know what to look/listen for.

A few times I've also encountered people who think their HDD is making bad noise when it's in fact the ball bearings on a fan that's gone bad.

Things that otherwise can make an HDD extra noisy (without it being on the verge of breaking) is high file fragmentation, disk being almost full, virus/malware or some bad software. Anti-virus software can sometimes do things way wrong and bog down a computer completely, seen that happen a lot of times because something just isn't 100% compatible.
