I really don't get it. I've spent the best part of an hour now checking part numbers on RAM to match correct ones to this motherboard. Its clearly listed as dual channel, not triple channel, yet the only RAM I can find in the parts list is triple channel RAM! I've now checked ebuyer.com and OCUK as well. Link to P7P55D board here: http://uk.asus.com/product.aspx?P_ID=yZD4yFdLw1l3gZ35&templete=2 I've attached the memory compatibility PDF to this post. Two RAM's that are on the list, but are triple channel: 1. OCZ http://www.ebuyer.com/product/158576 2. Crucial http://www.ebuyer.com/product/152640 I can't find a single dual channel package across both sites that is ON that memory compatability listing. I just can't make any sense of this. Surely if you put triple channel RAM in a dual channel supported motherboard you'd end up with single channel RAM, and therefore they're not actually compatible. I'm clearly missing something, but I thought dual channel RAM was for 2/4/8 slot combinations (and run in pairs), and triple channel (to run in 3's) in 3/6 slot combinations. What would happen if you used triple channel RAM in a dual channel RAM motherboard?
