Test: Kingston HyperX PC-9200 CL5 2GB kit

Kassens indhold

Rammene er pakket i en lille dobbeltsidet plastikæske med gennemsigtigt låg. Der er ikke noget ekstraudstyr med, men det var heller ikke forventet. Kun er lille folder trykt på genbrugspapir, med en beskivelse af hvordan modulerne monteres i bundkortet.



Det kan man strække ud over 10 punkter i beskrivelsen. Jeg kan ikke strække denne tekst længere, så i får nu en beskrivelse af rammenes elektriske egenskaber.

KHX9200D2K2/2G
2GB (1GB 128M x 64-Bit x 2 pcs.)
PC2-9200 CL5 240-Pin DIMM Kit

Description:
Kingston's KHX9600D2K2/2G består af 128M x 64-bit 1GB (1024MB) DDR2-1150 CL5
SDRAM (Synchronous DRAM) memory modules, baseret på seksten 64M x 8-bit DDR2 FBGA
Komponenter per modul. Total kapacitet er 2GB (2048MB).

Each module pair has been tested to run at DDR2-1150MHz at a latency timing of 5-5-5-15 at 2.3 - 2.35V. The SPD is programmed to JEDEC standard latency 800Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V.

Det betyder at du selv skal ind I BIOS og manuelt stille din ram-hastighed, spænding og timings hvis du vil køre over 800MHz. Default kører rammene altså PC-6400 ved 1.8V CL5.
