It mainly minimizes CPU utilization. For copying files and loading files,
you will likely not notice any difference. If you were to multitask or do
some CPU intensive operation in the background while hitting the HD, you
would notice the system becoming more sluggish than with DMA enabled. MS
claims that its DMA drives increase performance up to 40-60% in one of the
TechNet articles (forgive me if I am off... not trying to imply anything).
The DMA can have a significant effect in performance, but for the manner in
which most people use computers, the performance increase will be minor.
Ziff Davis benchmarks have proven that DMA drivers have very little impact
on performance when the OS is dedicated to benchmarking. Hence, unless your
CPU is maxed out, or you impose heavy heavy HD activity on your system, the
loss of DMA is small consolation for the removal of crackling and popping.

Your reply is consistent with my experience. I find that turning DMA off
really doesn't affect the performance much, at least the way I use the my
computer. The benchmarks may say it does, but this is only during brief
periods when the hard drive is being accessed while demands are made on the
CPU. Playing 3D games, like Drakan with DMA off seems fine to me.

Thanks for the intelligent and well-informed response.

I use DMA and have never heard "crackling and popping".  CPU idling
programs are known for producing excessive noise that can interfere
with sound systems.  Anybody else ever here of DMA causing excessive
noise?

I am DMA,running soundblaster live cars with creative labs 5 speaker surround
sound system,no noises from speakers,also using creative labs 48x cdrom ,

It does makew a substantial differnce in your system. I do a lot of video and
pictures. It helps acxcessing these larger files,especially having 3 or 4
applications running with 2 or more accessing files .

The difference could be up to 16 megs per sec. I am running 2- 27 gig, 7200,66mbs

hard drives. This really makes a noticeable difference even with   normal use.

Have to have a new motherboard that has the hardware on it to be able to take
advantage of 66Mbs.

For my 6.2x DVD-CD ROM drive, I would get noise when playing DVD's
unless I enabled UDMA in Bios, and in Win '98. Drive shows up as
UDMA2, and also plays jerky unless UDMA is selected, so for DVD's
at least, UDMA does make a huge difference, and was required for my
system that includes a Live! card, and Voodoo3 without any DVD hardware
decoder.

So when are they going to fix it?
I have exactly the same problem.

Share what you know. Learn what you don't.

The only information I have on the subject is from the SBLive! website.  If
you want further information there is a support page on the SBLive! site.
If you are European, the URL is

http://www.europe.soundblaster.com/techknow/

If you do get some information from creative about this problem.  Can you
email me with the information they give as I am intrigued about this
situation myself, even though I don't have the problem.  My email address is

gse1@rocketmail.com

Cheers!
