AGP Apperture?

[Busy]

U programu Aida32 mi pod stavci Chipset pise problem:
"AGP nije omogućen.Moguć pad performansi." i
"AGP Apperture size je više od polovice sistemske memorije.Moguć pad performansi"!!!
i ne kuzim o cem je tu rijec, pa ako neko zna bio bih zahvalan na objasnjenjui sto da ucinim u svezi toga...
šta je to AGP Apperture?

AGP apperture ti je opcija pomocu koje kada ti na video kartici ponestane memorije da se korisiti sistemska memorija. obicno se stavlja manje od polovice. tako recimo ako stavis 64 Mb toliko glavne memorije je rezervirano samo za video memoriju.

to se moze u windozima namjestit il se mora u biosu?

[LorD ClockaN]

Samo u biosu

mislim da je 128mb najbolje

Je da ali koliko sam uspio vidjeti zapravo koliko memorije stavis u apperture toliko izgubis za system. moze biti da se varam ali ti zapravo time zapravo reerviras iskljucivo za potrebe video memorije.

ne gubiš,on koristi sistemsku memoriju onoliko dugo koliko grafulji treba,poslije je opet na usluzi sustavu...

da ali recimo dok igras ta ti memorija cijelo vrijeme ostaje rezervirana za graficku i time gubis radnu memoriju. dakle kad igras na 256 mb i stavis 128 apparture zapravo samo sa 128 raspolazes. tak bar ja mislim, negdje sam o tome cital.

AGP Aperture Size

This BIOS feature does two things. It selects the size of the AGP aperture and it determines the size of the GART (Graphics Address Relocation Table).

The aperture is a portion of the PCI memory address range that is dedicated for use as AGP memory address space while the GART is a translation table that translates AGP memory addresses into actual memory addresses which are often fragmented. The GART allows the graphics card to see the memory region available to it as a contiguous piece of memory range.

Host cycles that hit the aperture range are forwarded to the AGP bus without need for translation. The aperture size also determines the maximum amount of system memory that can be allocated to the AGP graphics card for texture storage.

Please note that the AGP aperture is merely address space, not actual physical memory in use. Although it is very common to hear people recommending that the AGP aperture size should be half the size of system memory, that is wrong!

The requirement for AGP memory space shrinks as the graphics card's local memory increases in size. This is because the graphics card will have more local memory to dedicate to texture storage. So, if you upgrade to a graphics card with more memory, you shouldn't be "deceived" into thinking that you will need even more AGP memory! On the contrary, a smaller AGP memory space will be required.

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.

uuu... ..nice!!

ok moram proucit to napisano prvo prevest :clap:
e a kak onda da stavim ak imam graficku sa 128mb i 256mb radne?

[LorD ClockaN]

Samo ti stavi 128MB za AGP

Testovi su pokazali da je to najbolja opcija za rezultate

[Isus]

Stavi na 128 ak ti se sutav uspori stavi na 64
