Benching an older ATI video card?
 
Dont forget to disable hyper memory!

HKEY_LOCAL_MACHINE\SOFTWARE\ATI Technologies\CDS\0000\0\Memory

There will be an hypermemory string modify it to No (0x00000000) instead of Yes (0x00000001)

Ah, I fixed it It is working now.

I forgot i reinstalled drivers which means you have to redo the registry tweak.


Older cheap ATI video cards came with a feature called hypermemory. (Turbocache on nVidia) where, there would be 256MB of dedicated video on the card say, and it could access another 256MB of system memory, if the vmem bus got filled. Really hurts scores I bet.

Open regedit navigate your way to
HKEY_LOCAL_MACHINE\SOFTWARE\ATI Technologies\CDS\0000\0\Memory

Right click the key named "hypermemory" change it to

No (0x00000000)


restart.

Open regedit again (it should reopen right where you left it) and look underneath the hypermemory key.. the memory listed should now be the same as the whatever dedicated G-RAM is on the card.
