Re: Activating L3 cache on a Crescendo G4 400 card (powerMac 7300)
Ok,
Now the cache is enabled. I get the same Value as the GrabG3Cache Settings
app in the l2cr file. So seems to be OK. I'll try to do some benchmarks
during next week just to try to 'see' the difference more precisely ...
Thanx for your help !!
