M1330 whine...is it your CPU or Southbridge?

H3rmaN · 11-30-2007, 10:47 AM

Right, I've noticed that 99% of people are confusing CPU whine with Southbridge whine!

Can all of you who have ANY whine from your M1330 vote & post here?

You can tell if you have CPU whine if the noise is coming from the top left (by the CPU, surprisingly...), and you can tell if you have southbridge whine if the noise is coming from the bottom right, just under the express slot (the Intel 82801HBM chipset)!

I just want to know if CPU whine is more common than southbridge whine, or vice versa...

Cheers!

Well as of 5 minutes ago my laptop doesn't make a sound. The technician just left. He came to my work place and did his thing. So far it's performing really well.

My original m1330 the whine was too loud to determine where it came from. The replacement the whine came from two places. A faint whine from the top left, and a loud whine from the bottom right.

The motherboard was replaced on the replacement with an a04 board and now it's silent. Even if i put my ears next to the laptop i hear nothing.

The technician was good too, he asked for somewhere to sit down because, "the m1330 is very finickey." I got my boss to get him a desk close to where i work and about 30 minutes later he called me to inspect. So far, so good.

So this whine got me a free 2 year warranty upgrade (with next business day reparis) and, if things continue the way they are now, a very silent notebook.

I'm happy as hell right now that i chose dell

.

Edit:
Oh yeah, and the screen on this one is superb!!

Edit2: Although i appear to have no more whine, i voted southbridge, because that was the loudest whine.

Edit 3: Oh -cakes. It's whining again. bottom right. And well it was quiet for a couple hours. Lol.

The CPU whine, although minutely present on mine, is not bad enough to bother me. I can only hear it if I put my ear really close to the laptop. And I'm pretty sure I have the A01 motherboard, because I got my system in August.

only 7 votes so far, but 3 are for southbridge, 3 have no whine, and only 1 person has CPU whine....interesting!

This topic needs to be bumped. So here i go: Bump.

In regards to the southbridge whine. Has anyone noticed that when you make the computer load something the whining stops, the instant loading starts, then starts again when loading stops?

Try this: Open the start menu, and start clicking on some of the folders so that they expand. Don't click the same folder twice. Also try opening some programs. For instance, open MS Word, while the loading screen is on, the computer is silent.

It's a shame my computer is so fast, everything loads really fast so i don't get much silence.

Also note that i found loading web pages doesn't make the whining stop.

Can someone try what i just said to try and let me know if the whining stops for the couple seconds that it takes for programs to load? Also anyone have any idea why this is happening? And what exactly is southbridge? A manufacturer? If so what do they make?

I don't have a M1330, but I was thinking capacitors sometimes make a whine. So maybe the motherboard changes some capacitors.

ellianth: that same thing is happening with mine. although the southbridge whine for me is minimal, if i open/load MS word, the whining will temporarily stop while it's loading......albeit only for a couple seconds or so :T

anybody know why this is? and what exactly is southbridge for that matter?

capacitors dont whine mate...its transistors that whine! And these days we have 100's of millions of transistors within the chips. There's not a single capacitor within a chip!

I know for a fact its the 82801HBM southbridge cos me & my mate took apart his M1330 to find out where the whine was coming from, and it turned out to be the 82801HBM southbridge (noise was coming from under the express slot)!

The current poll results show that 60% of M1330 owners have whine coming from the southbridge!
