Kingston HyperX KHX4000/256
We had two DDR500 modules in two packages.
2x256Mb Kingston HyperX KHX4000/256
This is the standard package of the HyperX series: a small plastic box with a transparent cover that holds the module in its place by means of special juts. A detailed installation guide lies beneath the module. The colorful sticker displays the product marking and the company and HyperX logos. It’s glued in such a way that you cannot open the package without tearing it off.
Kingston took a simple way to solving the cooling problem: traditional aluminum heatsinks with metal clips. The heatsinks are anodized to blue color and their descent is indicated by the colorful Kingston and HyperX logos. By the way, in comparison to older HyperX series, the heat-spreaders have become brighter, while the logos used to be white – the company has made some progress. The module carries a sticker with some technical info, like the rated Vdimm (= 2.6V).
Kingston uses chips from Hynix in these modules as the package indicates:
Overclocking brought average results. The ceiling for the standard timings (3-8-4-4) was 257MHz (DDR514). After the Vdimm went up to 3.3V, the testbed was stable until 272MHz (DDR542). Such results may be a proof of the fact that kits of two compatibility-tested modules are a good idea after all. On the other hand, the more probable explanation lies in the low overclockability of the memory chips (Hynix D5) – this supposition is confirmed by the results of the tested original Hynix modules.
