I just got a RAIDR Express to improve the performance of my photoshop scratch disk and very large lightroom catalog. The OS and programs are on 2 other ssds in RAID, so I thought it would be essentially plug and play, but it took many hours and a few crashes for the install on a P6X58D Premium board. The system is now finally stable, but at idle with nothing open but task manager, 18g of ram out of 24g are being used. With the RAIDR removed, the system idles at 2g of RAM. There is no ramdisk or any other action taking place. I've talked with 4 people so far at Asus, and they're still working on it.
I ended up using the provided Marvel driver, and the lower slot on the X58 in the 16-8-8 configuration. Any idea what's happening with the RAM?
Thanks
