system/video BIOS cacheable

jepherz · Oct 22, 2004, 03:00 AM

i went to omegadrivers.com and got my radeon 950 softmoded to 9700,. then i saw this thing under ms bios. it gave a list of BIOs settings you could change to make your omega driver perform more better.

anywho, there are only 4 options i have that are listed there. is that possible? thats so little.

AGP sperture size
Init display first
system BIOS cacheable
video RAM cacheable

the thing is though, my BIOS listed video RAM cacheable as video BIOS cacheable. are they the same? =/ just to make sure before i change that one

edit:
what do the system and video bios cacheable do anyways? it said to disable them...

[color=white]Disable this. You don't want to be wasting the L2 cache on fast video RAM when you have slow system RAM to deal with. The bandwidth of your system RAM is unlikely to be over 3GB/sec, yet video RAM can easily top 10GB/sec and a 4x AGP bus is 533MB/sec. The tiny amounts of L2 we get these days to go with our massive system RAM sizes relegate this setting to being Disabled.[/color][/color]

yep...neon's right....although if you mgiht give 64MB aperture size a shot and see which runs better...I can run either without noticing much difference, personally.
