Dual, triple, or quad mean nothing as far as the RAM or motherboard compatibility are concerned. All that means is the modules in the packaging are of the same specs. Long ago (dual-channel has been around for almost 10 years), it meant they were tested to ensure they exactly matched but chipsets have become more tolerant of differences and advances in RAM manufacturing technology has resulted in all RAM of the same specs having much tighter tolerances.
So, when you see RAM packaged as dual, triple or quad, that is simply marketing and packaging labeling to get consumers to buy in quantity. It also means the RAM makers save money in packaging and printing costs by sticking 2, 3, or 4 sticks in one package. The advantage to consumers is convenience and hopefully, the maker has passed some of that savings on to consumers and buying sets is cheaper, if only a little, than individually.
Since that motherboard is dual-channel, you need your RAM in pairs to take advantage of dual-channel. Quad is just 2 x dual.
I don't see an OS listed. Understand that you are building a new computer therefore you MUST buy a new Windows license. You CANNOT
use a Windows disk that came with or was bought for another computer. That is stealing - illegal use of copyrighted software. The ONLY
exception is if the Windows license is a "retail" license that was purchased separately at a retail outlet and that is not typical. So again, cannot use an OEM or upgrade license that was purchased for another computer on a new computer. Period.
Also, note that if the Intel CPU you buy is a "retail" or "boxed" version that comes with an Intel supplied heatsink fan assembly, using ANY other cooler besides the one provided by Intel voids the warranty! AMD has the same policy.
As far as the Windows licensing and CPU warranties, I'm just the messenger. If you want proof, it is in your Windows EULA
and on the Intel CPU Warranty Information
and AMD CPU Warranty Information
