Depends on the refresh rate and resolution you use. The faster RAMDAC
allows for higher refresh rates at higher resolution, so if you don't
use high resolutions it probably won't matter much.

The boxed version of the Millennium should have a 220MHz RAMDAC. If you
get a 175MHz RAMDAC than it is the OEM version. I'm not sure if it is
legal or not.
One last thing. What does OEM mean? Does that mean it ships with a new
PC
only?
Yes, OEM products are meant to be sold to hardware manufacturers (PC
maunfacturers such as Gateway) so that they can put the hardware into
their computers.

I see there have been recent discussions about Millennium RAMDAC speeds.
What is the difference between the two versions, 175MHz and 220MHz, and
would you notice it doing everyday applications?
Also if you buy a Millennium off the shelf, i.e. in a box as a standalone
component, should you get the 175MHz or the 220MHz. If you get the 175MHz
version, is it legal?
I live in Australia so the laws here may be different but I doubt it.
One last thing. What does OEM mean? Does that mean it ships with a new PC
only?
Any help appreciated

Hello !

I have a 220MHz Millennium.
The big diffrence is that a 220 MHz RAMDAC version of Millennium can
do up to 85 Hz at 1600x1200 , and 1280x1024 at 100Hz for exampel.
Since I do not know the exact specifications for Millennium with
175MHz RAMDAC , I can only compare with Matrox Mystique that has
170MHz RAMDAC . That will at least give you some info to take into
conciderations what the RAMDAC speed will do for you.
Basically this is what a Millennium 220 MHz RAMDAC and a Mystique 170
MHz RAMDAC can do regarding color depth(2D and 3D) and vertical
refresh rates:
1. Colors.
a) In 3D: =20
2Mb 4Mb 8Mb =20
Millennium : =20
1600x1200 - - 256 (8bit)
1280x1024 - 256 65000 (16bit)
1152x882 - 256 65000
1024x768 - 256 16,7 milj (24bit)
800x600 256 65000 16,7
640x480 65000 16,7 16,7
Mystique
(dubble buffred): =20
1600x1200 - - 65000
1280x1024 - - 65000
1152x882 - 65000 16,7
1024x768 - 65000 16,7
800x600 65000 16,7 16,7
640x480 16,7 16,7 16,7
b) In 2D:
2Mb 4Mb 8Mb
Millennium:
1600x1200 256 65000 16,7 milj
1280x1024 256 16,7 16,7
1152x882 65000 16,7 16,7
1024x768 65000 16,7 16,7
800x600 16,7 16,7 16,7
640x480 16,7 16,7 16,7
(Millennium can also use 32 bit pixel depth in some resolutions)
Mystique:
1600x1200 256 65000 65000
1280x1024 256 16,7 16,7
1152x882 65000 16,7 16,7
1024x768 65000 16,7 16,7
800x600 16,7 16,7 16,7
640x480 16,7 16,7 16,7
(Mystique can also use 32bit pixel depth in some resolutions)
2. Max vertical frequency.=20
Millennium 220MHz RAMDAC:
1200x1600 85Hz , se Matrox website (78Hz in my Manual and 72Hz in
24 bit according to my Manual.)
1280x1024 100
1152x882 110
1024x768 130
800x600 200
640x480 200
(Millennium is also available in 170MHz RAMDAC version, but I do not
know the specifications for it.)
Mystique 170MHz RAMDAC:
1600x1200 65Hz
1280x1024 90
1152x882 115
1024x768 130
800x600 160
640x480 200
My conclusion is that it is in 1600x1200 the 220MHz RAMDAC has the
big advantage, because of higher vertical refresh rates(=3D less chance
of flicker for your eyes).
I think the 175 MHz version of Millennium also has dual ported WRAM
memmory , like the 220MHz version . That means faster redraw of the
screen since data can go into and out of the card at the same time.
Mystique for exampel has not dual ported WRAM , it has singel ported
SGRAM .=20
I do not know what everyday applicatons you use , but if you use for
exampel Microsoft Office , Works etc and that kind of programs I
think you will do fine with a 175 MHz version.=20
If your everyday applications are for graphics programs like
Photoshop , 3D programs etc I would go for the 220 MHz version=20
and at least 4Mb memmory.
>Also if you buy a Millennium off the shelf, i.e. in a box as a =
standalone

If you have the money , 220 MHz version. Why? Se above if you think
it might be needed in your case.

What can be illegal with a 175 MHz version ?

OEM=3DOrginal Equipement Manufacturer.
The exact meaning I do not know , but if you buy a OEM product you
will often not get a box , perhaps no manual , no extra bundled games
maybe etc.
Many PC builder use OEM products when they build a PC since it is
cheaper to use a OEM instead of a retail, boxed, product.
Exampel: I bought a Mystique some months ago and it was an OEM and
I only got the Card and a CD with drivers ets. No Manual , no box ,
etc.
Hope you understand the diffrence (and I have understood the OEM
concept reasonably correct).

PS. Matrox is releasing a new Millennium soon , called Millennium II.
Planed for released in June -in 1 -2 months...=20
Can be worth waiting for.

OEM stands for Original Equipment Manufacturer. And yes it should ship
as an added value item with a new PC.

The only way you would notice this is if you start running 1600x1200 at
75Hz or better. Everything else should squeeze in below 175MHz.
