I've ordered my Crosshair IV motherboard and did some extra research on my RAM. I started to confuse the heck out of myself (since this is my first build). I went to the ASUS site and downloaded the pdf file which talked about which RAM and vendors were recommended- however that only confused me more. I need someone to tell me exactly what RAM to buy when I'm looking to fill my machine with 8gb's worth. Thanks so much for the help.
Im having the same issue. I’ve bought everything but the ram same mobo and processor. I was wondering what you decided on I have to make up my mind so I'm not sitting here all weekend with all the parts but the ram. It is a issue and apparently mobo is sensitive to types of memory. I called mushkin they said to use there black line series running at 1600 corsair said to run there dominator series. Ive heard other recommend gskill flare but did not find any available.
A QVL (qualified Vendors List) should help you alot, because it lists the sets of ram that have been tested with the mobo, and should work with the system. The list should include information about the timings/voltage/part number. Search up the part numbers and see which one you like. Lower Latency is better for you, since looking at your build tells me that you are in for some quite heavy gaming.
Hope this helps a bit, if you're still confused, link me/us to the link and pdf you downloaded.
