128mb is fine.

It is recommended that you keep the AGP aperture around 64MB to 128MB in size, even if your graphics card has a lot of onboard memory. This allows flexibility in the event that you actually need extra memory for texture storage. It will also keep the GART (Graphics Address Relocation Table) within a reasonable size.

sideband addressing

A feature of AGP. Sideband addressing provides additional channels for transmitting data requests between the graphics processor and the system.

i use 64 on my g4TI4200 128mb

How much system ram do you have? 128mb is usually fine, though whatever you set it a won't make that much difference.

 

[BFG10K]

In most cases just leave it at the default BIOS values and it'll work fine.

 

[PCTweaker5]

Fine but not best. It usually works best at 128-256 depending on how much RAM you have.

 

[Hav0k99]

I have a gig of ram and have not noticed a difference betweeen 64 and 128mb.

 

[Gamingphreek]

The rule of thumb is 1/2 your system RAM. You probably wont notice a difference at all tho.

BFG Tech recommends setting it to equal the amount of RAM on your Video Card.

It's usually in the range of 64-256 anyway and you usually won't see much/any difference in that range. The difference can come if you set it too high or too low.

Best piece of advice so far.

 

[Gamingphreek]

BFG has no clue what they talk about half the time. The rule of thumb is 1/2 system RAM. Why would they have a 512mb option in older M/B's if there aren't any 512mb cards. :roll:

Yeah... BFG... pffft... those bunch of schmucks... all they do is make video cards... they have no idea what they're talking about.

Lol, that was good. However what i meant and should have written was: BFG as a company knows enough but some of their technicians and support dont know what they are talking about half the time. Theyve given a lot of nonsense suggestions before.

I think that goes for all tech support out there. Most of them think that us end users dont know jack about computers and tell us to do all these things that weve already tried several times. As much as I dont like them techies I wouldnt mind having that kind of job since I enjoy helping people with their PC probs. Some people that is.

 

[Big Lar]

I have always left mine at whatever bios defaults to, but, I have found that Far Cry does run better,( for me anyhow), with the amount of ram I have on the card. Go figure.

It was said in the instruction manual that came with my 5900.

That`s wrong,if you only have 128mb of system ram with a 128mb video card ,would you set it to 128mb AGP size?No you would not,to make it clear normally half the main size of system ram is all that`s needed,you can play around with the figure if you`ve lots of system ram,however the main AGP settings range from 64mb to 256mb depending on how much ram you`ve.




Good info on AGP aperture size below.

First of all, AGP Aperture memory will not be used until your video card's on-board memory is running low. That means it will usually not impact your gaming performance because developers are trying hard to not exceed the on-board memory limits.The bigger your video memory, the smaller your Aperture Size could be. However with later games requiring more and more texture memory a good number seems to be 128MB Aperture Size for all cards with 64 MB to 256 MB Video RAM

128Mb is a very common size because most of us have at least 256mb - 512mb of system ram,if you`ve 1GB then you can really play with the AGP size,even though in general 128mb should be sufficient.

 

[MichaelZ]

i like 1:1 ratio. 128MB aperture to match the 128 on the card.

 

[Jeff7181]

What a f-ed up scenario that is. Nobody's had just 128 MB of RAM in a gaming system since Half Life first came out... and there weren't 128 MB video cards then either.

My point being it depends on your system ram and your video card that you`ve in your system end of story.


In my old PC I`ve 256mb of system ram and 64mb video card,I set it at 64mb AGP size, see my point

Btw I know some gamers that only have 128mb system ram,too poor to afford to upgrade at this time.

Yet well, they can't play many games too well. So why bother.

It makes sense for the 1:1 ratio, and the memory won't be used up by the GPU, if it's used up by the CPU.

That`s true, however if you`ve a 256mb video card with 512mb or more main ram,you could argue you don`t need more then 64mb AGP size,so it`s all relative .
