LoL - yes, sorry, A RAMDISK. I thought people would know what I was talking about when I said, "Mounting the RAM as a drive."
At this point the only thing you can really do with a RAMDISK is use it for your paging file. You can't use it for anything else really because as soon as you turn off your PC, you'll lose all the data on the drive. Like I said before, "Windows XP loves to use the paging file." Even if you have 4GIG'S it's still going to try to page, that's what it's programmed to do. That's because 99.9% of windows XP users won't have 4GIGS. So if you do have it, it won't be used. So why not satisfy XP and use all your RAM? DDR is currently over 1000 times faster then even a 15,000RPM HDD. So you tell me what kind of performance increase you'll get from setting up a 2GIG RAMDISK and setting your paging file to reside on that Disk.
Gigabyte has designed a PCI card that holds up to 4GIG of DDR. It also has a battery that recharges while the PC is on. THen when it's off, the battery continues to power the DDR so it will retain the DATA. Might be a nice idea, but PC's now adays are rather lacking in extra PCI slots.
IF they designed it for PCI Express 1X it might be much better.
