Is there any reason not to on a WinXP Home ACPI mode system?......

Intel Chipsets need to have UDMA 66 enabled for Win2k and XP. This also enables UDMA100
HKEY_LOCAL_MACHINESystemCurrentControlSetControlClass
{4D36E96A-E325-11CE-BFC1-08002BE10318}000
You will need to add this value in
Right click and select New..DWORD
Type EnableUDMA66 and hit Enter..and Double click it and put the value to 1
It should the look like this:
EnableUDMA66=dword:00000001
Again, this is really only for intel chipsets.

Remove the Shared Documents folders from My Computer:
Windows XP user interface provides links to all of the Shared Documents folders on your system,
right at the top of the My Computer window.

NTFS Disk Performance
The NTFS file system is the recommended file system because of its advantages in terms of
reliability and security and because it is required for large drive sizes. However, these advantages
come with some overhead. You can modify some functionality to improve NTFS performance as follows:
1. Disable creation of short names. By default,NTFS generates the style of file name for compatibility
with MS-DOS and Windows 3.x clients. If you are not supporting these types of clients, you can turn off
this setting by changing the default
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFilesystem
NtfsDisable8dot3NameCreation set value to 1

2. Disable last access update. By default NTFS updates the date and time stamp of the last
access on directories this update process can slow performance. To disable:
HKEY_LOCAL_MACHINESYSTEMCurrentContolSetControlFilesystem
You will need to enter this as a new Dword:
NtfsDisableLastAccessUpdate set value to 1
3. Reserve space for the master file table.
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystem.
You will need to enter this as a new Dword
NtfsMftZoneReservation set to 1

Reboot after making changes.
Speed up the Start Menu in Windows XP.
HKEY_CURRENT_USERControlPanelDesktop
MenuShowDelay file set to 1
Click OK.
A restart is needed to see the results
Increase IRQ Priority of CMOS Real-time Clock
Improve overall system performance by increasing the IRQ priority of the CMOS real-time clock.
HKEY_LOCAL_MACHINESystemCurrentControlSetControlPriorityControl
You will need to enter this as a new Dword:
"IRQ8Priority" set to 1

Windows Explorer caches DLLs(Dynamic-Link Libraries)in memory for a period of time after
the application using them has been closed. This can be an inefficient use of memory.
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer
Create a new DWORD sub-key named
"AlwaysUnloadDLL" set to 1
Restart Windows for the change to take effect.
Speed up CD Copying to Hard Drives
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystem
You will need to create a Key here. Right Click on the FileSystem folder and select New>Key
Name it CDFS
CacheSize, this must be added as a binary value, then type in this value: ff ff 00 00
Prefetch, this key must be added as a DWORD value, then type in this value: 4000 hex
PrefetchTail, this key must be added as a DWORD value, then type in this value: 4000 hex

I had already tried most of these tweaks, but the NtfsDisable8dot3NameCreation thing gave me problems: some software still relies on the 8.3 name scheme, although I can't recall which SW it was - must have been either SFP, Logic, Wavelab or Fruity, because that's what I basically use on my DAW. Without the 8.3 namespace one of these softwarepackages refused to install.

Thanks.
Anyone know anything about the SMBus....I think it's needed by the UAD-1 card, but seems not to have installed on my system?

Hey

Okay....tweaking is an option when computers ain't working as it should...but I would also like to add....
if it is'nt broken don't mess with your computer.

Also - did browse around at this site.
There were guidelines told you how to tweak your computer ,and to install your computer as a standard PC.....
But nothing written about if you have an HT system then this Standard PC mode does not support it......etcetera.......

nothing wrong with tweakin your system to the best.But people can really go wrong when tweakin and fixing and if they're not aware of how this will affect the overall performance in their computers!

Correct me if I am wrong...

In retrospect I think you're probably quite right, but it's a big 'if'.
I now believe my initial problems all stemmed from the assumption that the computer I bought had been set up correctly for music.....but I just couldn't get anything to work in WinXP ACPI mode, which is why I went down the Standard mode + tweaks route.
I now have a second installation in ACPI mode, and I think I've discovered the key to success.....just doing everything in the right order:
1.Format;
2.Install OS;
3.Update Chipset Inf- this was absolutely fundamental, and I think why the thing didn't work out of the box in the first place;
4.Optimize certain Windows settings...disable graphics acceleration + fx, adjust for 'best performance' etc;
5.Install soundcard, MIDI, then sequencer.

I do believe there are a few tweaks that are important...the UDMA66 mode for Intel Chipset machines for instance, and I don't see the point of having remote access & networking services running if your not even on the net......oh, and 'error reporting' is a complete pain...and...oh somebody stop me- I was trying to agree with you and now I'm batting for the other side.
Well you are right not to fix something that's not broken, but you CAN definitely tune for more performance if that's what you want.......it is a risky business of course, but you can learn a lot from a few mistakes, and who wants to play safe anyway ?

1. Disable creation of short names:

Some setup programs still uses old name space. If this is disabled, installations get messed up.

2. Disable last access update:

Windows XP has a feature, which compresses files that are not used in a certain perioid. If you disable last access update, you'll notice very soon that your whole hard disk is being compressed.

Both comments I say, based on personal experience in practice.

I do

(for who doesn't knows me yet: that's why I'm on mac, less unsure factors).

edit: what a nerd am I, eh?
