- - SLI od Dvi (https://forum.pcekspert.com/showthread.php?t=41365)

Evo pitanje za znalce.

Oce li radit SLI mod kod kartica istog tipa ali razlicite kolicine memorije i brzine jezge npr. ova koju sada imam i recimo Gainwardova 7900 GT GS sa 512 MB rama i clockom jezge na 550 MHz (moja ima 256 MB rama i radi na 450 MHz).

Koliko sam uspio procitat takve kemije bi trebale (teoretski) radit ali u tavom mixu jaca kartica se prilagodjava slabijoj tj spusta se na takt slabije.

Ima ko iskustava ili koji korisni www link :)

ps- ovo je mozda najava prodaje (po povoljnoj cijenei) moje 7900 gt Point of View pa ako je nako zaiteresiran nek se javi za eventualnu rezervaciju doticne : cheers2

Ne. :D
Grafe moraju biti, barm kolko ja znam, jednake,a to se odnosi na BIOS (nije nužno),proizvodjac i vrsta memorije...

Ovo je sa Slizone FAQ

Can I mix and match graphics cards?

Citiraj:

In order to provide optimal symmetric scaling, SLI Technology requires the NVIDIA GPU to match. For example, a GeForce 7800 GTX must be paired with another GeForce 7800 GTX. Likewise, a GeForce 6600 GT must be paired with another GeForce 6600 GT. However, using the latest Release 80 Graphics Drivers, NVIDIA GPUs sold by different manufacturers can be used together in SLI Mode. For example, a GeForce 7800 GT from vendor ABC can be matched with a GeForce 7800 GT from vendor XYZ.

...znači brzina i proizvođač nisu bitni ali kartice moraju biti istog tipa...

mislim da je bitna kolicina memorije - dakle ak je tvoja 256 i druga trebala bi biti 256 , a ne 512 .

Evo opet sa Slizone:

Can I mix and match graphics cards with different sizes of memory?

Citiraj:

While it is not recommended, NVIDIA does offer this flexibility using Coolbits. When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. For example, if your first card is a GeForce 6600 GT with 128MB of memory, you should purchase a second GeForce 6600 GT with 128MB of memory. However, using Coolbits (value set to 18), customers can force both of the cards to use the lower of the two memory sizes and operate together in SLI Mode. When dissimilar memory sizes are enabled to work together using Coolbits, the effective memory size for each card becomes the smaller of the two memory sizes.

... ukratko iako se ne preporučuje - zbog toga što će obje kartice koristiti najmanji mogući nazivnik tj. manju količinu memorije - moguće je upariti dvije kartice sa različitom količinom memorije koristeći 'cooolbits'-e...

mora ti biti samo isti chip znaci 2x6600, 2x6800, 2x7800 a prizovdac i nije toliko bitan ali ako uzmes dvije razlicite ona brza ce se prilagodit sporijoj i tako ce raditi
