If you run out of Vram, would another GPU help?

post #1 of 13

Title says the question,

If a game is beeing bottlenecked by Vram, would running SLI or Crossfire help because you are then adding another GPU?

I know Vram is not additive

No. it wouldnt. get a gpu with more ram
post #5 of 13
Nope, if anything it'll hurt more, as the primary GPU has to duplicate some registers and keep data on what the second card is up to. It's not much extra v-ram use, but it's some, and if you're already running out, it won't help a bit.

I did not ask if memory was additive, I just added that because I knew that someone would mention it

I know you didn't ask. You made a statement in your "question post" - and answered your own question.

VRAM in SLI / Crossfire does not add up. Therefore, it won't help. Data left out will be fetched from the main RAM or the HDD /SSD.

This. If you knew you didn't get any extra RAM from SLI/Crossfire, how did you imagine SLI/Crossfire would help if you're running out of RAM?

Nope.
