The first point to mention that I live in Spain and have purchased the storage latch on Amazon.es. Since my old system is already more than 5 years old, I decided for a basic upgrade. In principle, all components have been replaced to the case and the hard drive. The Kingston HyperX Savage 2x8 GB Riegel be operated on an Asus Z97-Pro motherboard. A total of up to 4 DDR3 modules can be installed with a maximum of 32GB. The Kingston Memory detected easily and works under Windows 8.1 64bit properly. All programs and games run stable. The memory modules also make a purely visual impression of high quality. So far I'm very pleased with the new Kingston memory and can recommend it without hesitation. On Amazon.es memory (2x8GB) for about 140 Euro is offered.
