Hi, I just bought some Kingston HyperX PC8500 RAM form ebay. The box and the sticker on the actual memory actually says it is PC8500... but when I run a check on CPUZ, it actually shows that it is a PC6400... is that normal or have I been scammed? I am running 2x Kingston HyperX PC8500 and also 2x OCZ XMS2 PC6400 Ram. All these rams are actually 1GB each which totals 4GB... it says that on the booting screen but for some reason, when I get into vista, it only shows 2GB... any reason for that?
