have just installed new memory and as part of the recommended troubleshooting (only shows 3.25 gig out of 4g) updated the bios; everything seems ok except that the fan speed has doubled from normal 1750 rpm to about 3400 and it doesn't vary much from this. Its orribly noisy and I guess not too good for the fan! Can't see any OBVIOUS way to change this in bios, though I'm not very knowledgable about this, so don't want to poke about too much. I have got speedfan installed but have only been USING it to monitor temps. So do I change in bios or speedfan, or reinstall
bios update? Or .........? Thanks.


Packard BELL imedia 1559 2.8ghz, Phoenix Award Workstation bios, XP proYou will only see 3.2 gigs with xp Pro 32 bit. Xp 64 bit or Vista 64 bit has the ability of using more than 3.2 gigs of ram.

As far as your fan, is there a setting in your bios that allows the computer to adjust the speed of the fan according to how warm the cpu is? I forget what it is called.hejlik:
thanks for yr reply. You nearly made me happy that my os was the problem (at least I knew the answer!) But then I did a google and Bill Gates said
"The maximum amount of memory that can be SUPPORTED on Windows XP Professional and Windows Server 2003 is also 4 GB."

I bought 4g because the Packard Bell web site said that was max for my machine, but of course they didn't know I'd installed xp pro instead of oem xp home ed. So could you tell me where the info about 3.2 gb being max on xp pro is ?
It doesn't really bother me too much about usable ram v installed ram - 3.25 is a good jump- up from 1gb, though I spose some bit of me would like to get my money's-worth; but I'd really like to get back to the
good ol days of fans that only worked when needed.

I have looked again in the bios and all it seems to offer me is enable/disable fan heat control but no further settingsThe max supported is 4 gigs with XP W2K etc....but with a 32 bit OS you will never see 4 gigs. You can only see about 3.25 gigs. Your machine is normal.

If you were running a 64 bit OS things would be differant.

Is the fan heat control setting ENABLED? yes, enabled................But I'll double check!!!......... ahha! but for some reason smart wasn't enabled in bios . Wonderful, peace again in West Wales! ( the sheep couldn't sleep cause they couldn't hear to count each other).
