I'm looking to resolve a problem which may not be a problem. I have just bought 4 x 2Gb of Kingston HyperX on eBay for my latest build. Each is clearly marked KHX8500D2K2/4G as two matched pairs and was advertised and purchased as DDR2 1066MHz. I fitted them to my MSI MS-7512 motherboard running a Xeon X3360 CPU and Windows 7 Pro and was surprised to find they came up as 800MHz in BIOS. In Speccy they were 400MHz, so dual channel again indicated 800MHz. I checked the manual to ensure everything in (AMI) BIOS was auto detected and using Memory Z I found the serial number of each module -
Seeing the prefix 800 on three of them has me worried. Memory Z also stated -
Max bandwidth DDR2-800 (PC2-6400, 400MHz)
Am I missing something or have I forgotten something? All the modules are clearly and identically labelled KHX8500D2K2/4G and show no signs of tampering. Any help most welcome. Please be aware that you will be communicating with a computer illiterate with limited knowledge.
