I have a custom built desktop PC running W7, I-7 920 CPU and a GIGABYTE GA-EX58-UD3R LGA 1366. I want to know what would be the best RAM for this system. The motherboard seems really fussy as to what RAM I install. I believe the maximum is 16 GB with 4GB per slot. I think with this motherboard everything about the RAM has to be the same (speed, voltage, brand etc), otherwise it will not recognize all of the RAM. I am getting alot of 12GB total (8 GB Usable), 8GB Total (4 GB Usable). Is the best most accurate indicator of total RAM installed and speed in the Bios or in the system whilst in windows.
I currently have 8GB total RAM installed, but only 4GB is recognized:
I believe my system is capable of 1600 MHZ in the RAM, but is this considered Overclocking the RAM or just normal XMP setting? What is the difference b/w Intel XMP (Extreme Memory Profile) Ready and Intel XMP (Extreme Memory Profile) Certified. The BXL Ram is more recent than the BRL. I would greatly appreciate some help on this topic. thanks
