Has the CPU "whine" on Intel CPUs been fixed?

I thought I heard that this problem was fixed (at least on most motherboards) with a hardware change about six weeks ago, but I might be imagining this. I know it at least used to be a possibility on pretty much any Intel notebook, but I haven't heard as much about it recently.

Can't really recommend Intel so long as this problem persists, so I'm hoping it's fixed soon. Would really like a software solution as well (RightMark causes freezing on battery) cause I don't really feel like sending my notebook back for repairs.

 

...

Seriously, not something to consider or really worry about.

Neither is it a reason not to recommend and Intel product.

I have an Intel CPU and I have NEVER had any CPU whine.

P.S. It's a Intel Core Duo T2400 1.83ghz.

 

The reason due to the "whining" sound is that it's overheating. And that maybe the bearing is a little off-kilter.

 

The whining is actually due to the way the voltage is regulated on the chipset when speedstep kicks in, which is why RM Clock works. I have had issues with it on my M1210, and not on my M1530 , so I think it's been fixed in the Santa Rosa platform.

 

I don't think it has to do with overheating. Otherwise you are essentially saying that all the manufacturers who had notebooks with CPU whine designed inadequate heatsinks that resulted in CPU overheating. I don't think this is the case. I believe it has something to do with throttling, sleep states, etc.

It hasn't been fixed on the Santa Rosa platform. I get CPU whine on my T61p when on battery.

 

Thanks for the info.

Yeah, I'm kinda use to desktops. Especially when my dad's PC runs any 'intensive' program.

 

i have tried T5470, T7300, T7500 and T7800 in vostro 1400, none has CPU whine.

 

I didn't mean it affected every Intel notebook, just that it affected some of pretty much every model, regardless of manufacturer (Dell, Apple, HP, etc.).

It's easy to say a problem isn't important if you don't have it. Try working in a quiet library with a notebook with the CPU whine and see if people don't notice. It's enough reason to recommend AMD to anyone who cares about noise if you've experienced it.

It's been established to be from the C3 and C4 sleep stages and throttling between them, as lmark84l said (+rep). It in fact occurs when the processor is not being worked, as only then is it idle enough to slip into the lower sleep stages.

Good to know. How new is the Vostro/processors?

----------

What I'd really like to know is, does this problem affect new motherboards/processors? Did a motherboard change fix the problem, or did a processor change fix it? Or is it still a problem affecting some new computers?

 

This problem is not only exclusive to Intel CPUs (which apparently whine while idle); it also happens with AMD CPUs (which whine while throttling up). My laptop is an example of this. In fact, there is a thread around NBR somewhere that discusses this issue.

 

My Vostro 1400 seems to whine when it is plugged in but not while being run on battery. Does anyone know if Dell will replace my CPU if i tell them its creating a whining noise, or will they just replace the motherboard instead?

Edit -And it whines only when on High Performance mode.

 

bought in August

 

Has the whine been fixed you asked?

I certainly hope so, I had a HP DV9000 series with the problem, 3 repair attempts later and I decided to get my money back.

Went with a Dell Inspiron 1720, still had the whine but nowhere near as noticeable as the HP's was. Sent it back for a replacement which arrives tomorrow. If it still has the whine I shall send it back again for another replacement. I shall keep doing so until I have a whine free notebook. Dell will be pretty fed up of me I'm thinking, but I won't settle for something of unsatisfactory quality that cost so much money!

I've been onto Intel and they know of the problem but they say there is no solution as yet. How they can keep selling notebooks with a known issue is beyond me. I think people should be told about the problem before they purchase. If they were made to do that then no one would be buying the products and Intel would have to find a solution a darn site quicker than they are doing now!
