Can these two be sli'ed? to do so, do i need to overclock the 512, or would the 1gb default to 512? i already have them, please dont suggest upgrades, i just cant seem to get these cards to sli correctly. thanks
But what about the memory? Can you add a 7800GTX 512 and use that with 7800GTX 256?
It's recommended to use a 7800GTX 256 with a 7800GTX 256 and 7800GTX 512 with 7800GTX 512.
However you can use a 7800GTX 256 with 7800GTX 512 , BUT the 7800GTX 512 will lower its RAM to 256MB to operate with the other card, so it wont have its true power. (This option isn't recommended. )
Are you using an SLI bridge? Have ou enabled SLI in the Nvidia control panel?
There is no clock synch and the clocks haven't been synch by the driver for past two years so just dump it in. However you may have issues due to memory mapping and yes you will be limited to just 512mb. It is enough for most games with appropriate settings and res but not for much longer. People are such noobs when it comes to sli -_-
i understand. its actually funny when it tells you. this mobo is weird. anyways, i wish i knew why nvidia control panel only gives the physx options and not the sli options. they're supposed to be in the same section.
so, i updated the chipset and bios drivers, then re-installed the gpu drivers to no prevail, nvidia control panel still doesnt show option to enable sli in the program. i feel like i have hit all the options. what am i missing?
A post like that which adds no new information and only "bumps" this thread to the top of the front page. If you read the sticky that outlines the rules then you would know that this is not acceptable.
