Needing to upgrade my ram, 1st because I need my current kit to go into a folding rig, and 2nd because many things I do, or would like to do, require a lot more than 6gbs. I'll looking at 16gb quad channel kits, because tri kits are pretty much not available up here anymore. I also realized going over my mobo manual, that I can use all 4, with one being in single channel mode. So I guess I want to know if that can impact overall performance? Also, looking at this vengence low profile kit, because nothing else will fit under my fan: http://ncix.com/products/?sku=62313&vpn=CML16GX3M4A1600C9B&manufacture=Corsair For these, I'm wondering if they are capable of 1800mhz at 9-9-9-24 like my el cheapo gskills are doing right now, so I can stay at 4.1ghz. I eventually want faster ram when I go water, so these are pretty much temp.
