In a local used sale I picked up two cabinets with X8ST3-F but they only included 3x2GB ram each. Getting more ram is expensive! Any reason to prefer this mainboard, or should I just keep one at 12GB and not use the other one? At $18 for 4GB it makes more sense to use my cheap X8DTL-3F mainboards that included 48GB (6x8GB) - or maybe even upgrade them, than to get the X8 up to 24GB ram for like $110 each...
