can you sli two different cards ? - Page 2

post #11 of 30
Sorry for hijacking the thread, but does two cards of the same type but with different companies work in SLI/Crossfire? Example being an 8800 GTX (EVGA) and an 8800 GTX (BFG) in SLI.

Yes but most of the time, if two cards are clocked different, it will pick the lower clocks are run them on both cards.

from the 7 series up you can use different manufacturs and and differenrt revisions of card they just need to be the same model

Unfortunately with Nvidia card you MUST have 2 matching cards to Enable SLI.

For ATI this is different you have to keep the same Model but you can mix XT or Pro for example.

It was a driver update (early 2006, I think) that allowed different different manufacturer and BIOS to run SLI. I believe you can run any 6800GS in SLI as long as you have recent drivers.

I wonder if you flashed the GS to a GT or the otherway around if that would work.

As for the 8800 GTX (EVGA) and an 8800 GTX (BFG) if one did have a higher overclock you could flash those, I know someone that flashed there PNY 8800GTX to a eVGA 8800GTX KO and it worked fine.

I'm pretty sure this would conflict. Although I seem to remember there was a hubub about nVidia allowing 2 different makers of the same model being able to SLI...don't remember though.

The following excerpts are taken from the SLI Zone Faqs

Quote:
Can I mix and match graphics cards?
In order to provide optimal symmetric scaling, SLI technology requires the NVIDIA GPUs 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 or later graphics drivers, NVIDIA GPUs sold by different manufacturers can be used together in an SLI configuration. For example, a GeForce 7800 GT from vendor ABC can be matched with a GeForce 7800 GT from vendor XYZ.
Quote:
Can I mix and match graphics cards if one of them is overclocked by the manufacturer?
Yes. A GeForce 7800 GTX that is overclocked (for example BFG GeForce 7800 GTX OC) can be mixed with a standard clocked GeForce 7800 GTX.
Quote:
Can I mix and match graphics cards with different sizes of memory?
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), you 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. Instructions to enable this feature can be found here. http://www.slizone.com/object/slizone_coolbits.html
http://www.slizone.com/page/slizone_faq.html

So how would you interpret OPTIMAL, meaning yes but with a big performance hit or something else.
