Summary: Great memory DIMMs. Super fast. No problem when attached to Z87-A ASUS board. 16GB is really too much but we cannot say what will be needed with future releases of Windows! I recommand them...
Summary: Good kit for Z87 motherboards with a decent price (especially with the current instant rebate). Based on many reviews, you should not expect crazy overclocking headroom (but some kits will probably overclock better than other). The kit I received on July 16th is the one with the black PCB version and not the (older) green one showed in the product pictures.
Pros: - Stable at sock speed, - Dual XMP profiles might help if the motherboard has issues running the memory at full speed, - Black instead of green PCB (If you care about that sort of thing)
Cons: - Marginal overclocking headroom, - Tall heatsink could be an issue with large coolers
Summary: You gave these modules a low rating because you are trying to use them on Mother Boards that will not support their speed. That is a MB problem - not a memory module problem. On a MB that will support 2400MHz they will run at 2400MHz as advertized.
Summary: This ram is capable of running 2400mhz, but just make sure your motherboard is compatible!!! So far motherboards are capable of running 2400mhz but most of their updates dont include this memory yet. My test mother board doesn't start when it's clocked at 2400 but since it supports this manufacturer at 2133 it runs flawlessly when clocked at that speed. Its super fast and worth the value though, cant wait for my new compatible mobo. I would definitely recommend this!
