Maximum RAM disk size with 512GB of memory
4 posts · Closed
Hi. Could you tell me, if I have 512GB of memory, can I create a RAM disk size of 400GB? Or does the RAM Disk have a max memory limit?
In theory, there is no limit on RAM disk size on 64-bit systems. The maximum size we have tested was about 200 GB, as we don't have the equipment with more RAM than that.
If for any reason you are having troubles creating a very large drive, try creating a few smaller drives instead.
Is there a way to find out if there are any size limitations in practice? I need to create an initial RAM disk of 300Gb, with a future RAMdisk of 500Gb-1TB.
Yes I have the RAM available, and using Windows 10 Pro.
As mentioned earlier, it wasn't physically possible for us to test RAM disks larger than 200 GB. If you have the hardware for 300GB-1TB RAM disks, the best way to test it is to download the free trial of the RAM Disk. It will give you a fully-functional application for 30 days, which should be enough for ensuring that everything works well with your setup.
