9500 pipeline depth ?????

[TMack]

I was working on mys son's PC which has a Radeon 9500 (which works fine). I
was using Powerstrip to check that sidebanding was enabled and that AGP
texture memory was available when I noticed that Powerstrip was reporting
the 'pipeline depth' as 80. Now I always thought that pipeline depth
followed the 'multiples of two' progression e.g. 32, 64, 128 etc. so I was
puzzled by the reported value of 80. Googling didn't provide any useful
info so out of curiosity I thought I would ask here - does anybody know
exactly what 'pipeline depth' means in this context and is a value of 80
unusual?

80 in hex is 128 decimal. Maybe Powerstrip is giving you the value in hex...

Depends on which 9500 you have, is it the 'np' non-pro, or the pro
version. Also was it the original reference spec or one of the
'locked' versions.

There were reference 9500's which:

- had 8 pipes, all open and available
- had 8 pipes, with 4 closed, but [ software ] moddable
- had 8 pipes, with 4 closed, but [ hardware ] moddable

To work out which one you have, both the open & closed moddable ones
had three things in common, see the URL below for representations:

- the PCB was red
- the memory chips were square not rectangular
- the memory chips were arranged in an ' L ' shape

If your card is red with square chips arranged in an ' L ' shape then
Christmas has come early in your house. I'm off to work, I'll look
back later - in the meantime someone else may jump in and help.

fine).

80 in hex is 128 decimal. Maybe Powerstrip is giving you the value in

hex...

But it gives a pipeline depth value of 256 for my 9700 which would be 598
decimal pro so I don't think that is the answer.

Unfortunately Christmas has passed - it is a 'moddable' version but is
unstable when modded - doesn't give the checkerboard effect but it
invariably locks up sooner or later when modded. It is completely stable
without the mod.

I don't know what powerstrip does / uses / interprets, but

Drivers from " omegacorner.com " will open these pipes if they are
there and openable, and ;

AIDA32 under display/GPU will tell you how many ' pipes ' are open!
even the ' Adapter type ' in - right click on the desktop / settings
/ advanced should show :

- chip type as 9700 BUT
-adapter string as a 9500

Powerstrip is clearly not referring to the NUMBER of pipelines - I don't
think the 9700 actually has 256 pipelines!
