Icarus2 Posted January 20, 2012 Posted January 20, 2012 If I have two videocards with an SLI bridge, but SLI is off and I plug the first monitor into the first card and the second monitor into the second card, will the second monitor use the vram of the second card. Is there any advatage to using two cards for two monitors.
PeterP Posted January 20, 2012 Posted January 20, 2012 (edited) whatever you do - plug your monitors first into the primary card - so the data has not to be copied trough the pci bus again. and as you are a multi-monitor user you may are interested in this: Triple-head/Multi-Monitor GUI and NVG Fix About the advantage: It is real "science" for its own... and I'm using AMD - but had plenty of Nvidia cards ... but I'm getting a little rusty on "what's up to date"... It highly depends on the drivers you get from your card vendor. Maybe others would like to elaborate more on this matter... Edited January 21, 2012 by PeterP
Kuky Posted January 21, 2012 Posted January 21, 2012 as far as I am aware there are no advantages in using 2 video cards for 2 monitors... only 1 card will be used for rendering in game and secondary will be used as bypass and only output what 1st card tells it to (all data will go through PCI buss as PeterP said) so best is to run all monitors of the same video card.
