Radeon 9600 PRO Overclocking

hmmm
Where?

[Ichneumon]

I take it the updated r3dtweak worked.

 

[Dave Baumann]

Yes, thanks Ichy. Went to 450 core speed first - all fine. Took it up to 500 - ran 3DM03 and RtCW fine.....

I'll have a bit more of a play and give some results.

 

[sireric]

As a note, the fastest we were able to overclock the 9600p engine was 506 MHz

Later

What blows my mind is that it seems it could compete with the 5800 Ultra with PS 2.0 and ARB fragment shaders.

 

[Dave Baumann]

520...

 

[Evildeus]

Good to know

Any idea for the 5600?

 

[Prometheus]

I wonder why Ati went so conservative with the radeon 9600pro clocks!! :?

Probably because it could potentially end up quite bandwidth limited, at which point faster memory is required -- which could get expensive.

 

[SvP]

Then why is the default clock so low?? :?

 

[Dave Baumann]

OK, I've just run the 3DMark03 DX9 shader tests at 520/300 with the same settings as the review, at 1024x768 with no artifacts or any other unusual signs. These are the results:

        GT4    PS2.0
400/300 18.7   27.9
520/300 23.1   31

Any idea for the 5600?

Not yet. I'll have a look at that later

This is what I'm wondering. This is a limited sample, but overclocks like this would suggest they could go further - they may have relatively easily bested the 9500 PRO with these clocks! Perhaps they are keeping something in reserve.

I don't think so...

Some Testboards has got the same Mem that is used by Radeon 9700 PRO Cards...

 

[gokickrocks]

is this on stock cooling?

 

[Dave Baumann]

I'm tempted to peel the tiny little HSF off this and stick the 9700 one on there, see what it'll to then!!

 

[Saem]

520...

Sweet zombie Jeebus!

Isn't radeon 9600 pro using 700Mhz capable memory chips?
They could have gone for a 450/700 config.

If so, then. . . I guess Dave has something more to check!

Yes, Thilo from PC-Games Hardware said that there are 2,86ns RAM Chips on his Radeon 9600.

But he also said that he was not able to overclock the Memory 1MHz.

 

[Evildeus]

Thx Dave. Perhaps the yiels is at is best at this clock rate?

What about OC the memory?

Waiting for the 5600 ultra OC.
