agt Posted March 31, 2013 Share Posted March 31, 2013 I hope I posted in the correct forum. My system is mentioned at the end of this post. It runs great! When I boot Win 8 x64, it appears that 1.4 GB of my 16 GB is already used. Is this normal? I am trying to understand what is using this memory. I do audio production using virtual instruments with large sample libraries and I want to make sure I am able to use as much of my RAM as possible. I have looked at the Corsair Memory Upgrade Resource Guides from 2008 ( http://forum.corsair.com/forums/showthread.php?t=71086&highlight=upgrade+resource ) and 2010 ( http://forum.corsair.com/forums/showthread.php?t=87341&highlight=upgrade+resource ). The 2008 Guide contains an example in which the operating system's available memory is reduced by the amount of onboard video memory. The 2010 guide does not contain such an example, but mentions motherboard usage of "block address space". Here is my question: Does the amount of memory on an installed PCIe graphics card impact the amount of system memory available? Would a card with 512MB of memory allow for more system memory than a card with 1GB or 2Gb? Or does this concept only apply to onboard graphics (built into the motherboard)? Thanks in advance!

peanutz94 Posted March 31, 2013 Share Posted March 31, 2013 system is mentioned at the end of this post. It runs great! When I boot Win 8 x64, it appears that 1.4 GB of my 16 GB is already used. Is this normal? Yes, the operating system and any other programs will consume a given amount of memory . The more programs you have installed the more memory that is used. The 2008 Guide contains an example in which the operating system's available memory is reduced by the amount of onboard video memory. The 2010 guide does not contain such an example, but mentions motherboard usage of "block address space". This generally is for on board graphics . But even a dedicated card will use some memory for drivers and games or what ever you have running off of it. A 512mb card vs a 1ig or 2 gig card really doesn't use any more system memory . It relies mostly on the memory built into the card. This is why it is better to have a video card with more onboard memory for better frame rates and rendering. Video card memory is completely different than system memory. Link to comment Share on other sites More sharing options...
