6800GS AGP - Overclocking?

[havegomac]

Hi All,

I did a quick search and couldn't find much on this subject.

I've got one of the OcUK 6800GS AGP Cards (which are absolutely stunning value for money).

Now that I've got it ... what are the overclocking options?

If it's just a Core/Memory overclock what can I go up to with the standard cooling?

Does it have unlockable pipes?

Standard Config is
- 350MHz Core Engine Clock speed
- 256MB 1000MHz high speed GDDR3 memory
- Superscalar 12-Pipe GPU Architecture

thanks!

You cant unlock the pipes and overclocking is different everycard - I say get ATI tool, let the programm find ** max mem/core overclock.
This wont be your most stable overclock - it clocks too much look at the picture chances are there will be a flashing black and white spot once in a while even thought it says no errors.
Once ATI tool find ** max overclock - move the memory down say 20 and core that much aswell, test them fo an hour while your watching it.
If thats stable and your temps are good try moving the core up or the memory.
What i tend to do is do the core by itself or the memory by itself so I dont have to figure out which one i overclocked too much.

The AGP cards are based on the NV40 core so unlocking pipes is possible although they may or may not work.

(The pci-e one is the ones you can't unlock the pipes on - NV42)

I thought they cut the pipes via a laser on the new cards.

Nope rivatuner can unlock them and the vertex shader, as stated it may or may not work. Have a go
