My old 9700 PRO would cause data corruption with large system cache enabled.

My 9800 PRO whenever I enabled it boot as 640x480x16 colours at 60 hertz every time.

What is the deal going on here?
 
Just out of curiosity, why are you trying to enable large system cache?

Is there a performance boost to be had from this? I seem to recall this from NT days for boosting server performance for servers with slow disk subsystems.

In any case, I don't know the answer to your question :) Maybe I can try it out after work today though, and see what happens with my 9800 :eek:
 
Bug in ATI drivers, I had it enabled when I got a 9700 Pro and for the life of me couldn't figure out what was wrong. Then I found out about this problem and was majorly pissed. I can't believe they still havn't fixed it yet *sigh* ATI.
I still love my 9800 Pro though :p
 
It´s because I got 1 gig of RAM and it is unused most of the time. Applications and stuff loads up faster that´s all. 3dprof has a "ati safe large system cache" may try that one
