This memory is Kingston's KHX1333C7D3K2/4GX, a kit of 2GB (256M x 64-bit x 2 pcs.) DDR3-1333MHz CL7 240-pin DIMM Kit. Each module kit supports Intel® XMP (Extreme Memory Profiles). Total kit capacity is 4GB. Each module pair has been tested to run at DDR3-1333MHz at a low latency timing of 7-7-7-20 at 1.65V. The SPDs are programmed to JEDEC standard latency DDR3-1333MHz timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers and requires +1.5V. The following are JEDEC standard electrical and mechanical specifications:
The Kingston KHX1333C7D3K2/4GX is a 4 GB kit composed of two 2 GB DDR3-1333MHz CL7 modules. Each module uses 240‑pin DIMM design, gold contacts, and operates at 1.5 V with JEDEC‑standard timings.
The datasheet lists electrical, mechanical, and timing specifications, as well as features such as programmable latency, on‑die termination, and internal self‑calibration. It also includes operating and storage temperature ranges and module dimensions. This manual is written in Chinese.
