I have an overclocking question

[nick1985]

I unlocked the pipes succesfully on my friends Albatron 6800, so he has the full 16. But when I tried to overclock the mem and the core, it wouldnt let me. It would fail if i even tried to overclock the memory 1mhz. What is going on? This thing has a huge heatsink on it, so I would assume it would be able to overclock.

The pipes are defective, unfortunately. The reason it doesn't pass the test is because the card cannot run stably with the pipes unlocked and it has nothing to do with the overclock. If your friend wants to take a risk, you can use RivaTuner to have it bypass the internal clock test, but even Unwinder doesn't recommend that.

beee careful. I unlocked my 6800 a while back and it ran funny in games like Battlefield Vietnam. THe performance jump is not worth the 4 pipes you unlock... IMO. This is my 400th post

well after i unlocked the pipes, i ran 3dmark and saw no artifacts...

Go ahead and LOCK the pipelines back again. After you reboot see if it will pass the test by trying your memory overclock. If it does, go ahead and put the memory at the speed you want and have it set to Boot at those overclocked speeds.

Then unlock the pipes again and reboot. The overclock speeds will then be set.

This is about the only way I think you can do it if the internal test fails with the 4x extra pipes enabled.

Hope this helps

I would be VERY careful overclocking with the pipes unlocked. It's not some kind of bug-- it's the fact that your card cannot handle the pipes unlocked.

Unwinder's Official Statement

Guys, read it once again. Read it SLOWLY. During testing new clock frequency driver performs internal stress-testing, allowing it to detect system instability and rendering artifacts, which you may not see. If stress test fails on that clocks it means that enabled units DON'T work properly on the clocks you are trying to set. If stress test fails even on default clock+1MHz - you are out of luck. Try to boost core voltage and stop spamming me with this 'bugreport'. Simply think a bit.
You do may prevent RT from testing the clocks with DisableClockTesting, but it will not allow Coolbits to overclock higher and it will not make your system more stable than it currently is. You have problems with stability after enabling additional units, and don't fool yourself by disabling clock testing.
