Note:
The X600 Pro had only one version and its connector was called the
ATI 6110018300 (or the '300') connector.
The X800 XT had only one version and its connector was called the
ATI 6110018300 (or the '300') connector.
The X800 XL had only one version and its connector was called the ATI 6110020700G (or the '700G') connector.
Note: The X600 Pro and the X800 XT "shared" the same "Silver stab" connector (the '300'), but it was not the same as the X800 XL connector (the '700G'). The major differences are
(1) the 300 and 700G are not "swappable" that is you cannot substitute one for the other. They carry different signals on each pin.
(2) the 300 has F-type threaded RF connectors on the breakout side of the "Silver stab", the 700G does not have any F-type threaded RF connectors (none) it has two DIN connectors and it has a large chunky VGA female connector.
Other than the immediately recognizable "Silver stab" body these two different connectors share very little in common.
What confuses and throws people are:
A. That the X600 Pro "Silver stab" connectors are no longer available, this is true.. to a degree.. but a
complete ATI X800
XT kit will have a compatible connector. If you get stuck with a X600 Pro without the "Silver tab" you could pick up an X800
XT to go with it or vice versa.
B. The X800 XL "Silver stab" is still somewhat available, but it will not work with an X600 Pro.. so beware, people get one of those and then find out it doesn't work.. its not a bad X600 Pro.. its trying to use an incompatible "Silver stab" with that card. The card is probably still good. Notice this also goes for the X800 XT, you can't use the '700G' connector with an X800 XT either.
My personal experience with PCI express is that it was the only tech supported by DirectX 10 or 11 so if your a Vista or 7 (or even a W10) type of person.. and want to try (or force the issue) your more likely to succeed with one of the 'X' cards.
I have not succeeded satisfactorily yet!
I simply thought this a public service message to people who might be trashing X600 cards.. they have several ear marks that make me think they may be close to the quality of the 9600 cards.. just on a different bus form.. and woefully misunderstood.
one final bit of trivia.. there was an X800 XT (
AGP) card.. I do not have one, they are extremely rare.. but they do exist.. I am not sure why it exists, backwards compatiblity perhaps? But its out there.
