kvr13n9s8hk2/8 8gb (4gb 1rx8 512m x 64-bit x 2 pcs.) pc3-10600 cl9 240-pin dimm kit description valueram's kvr13n9s8hk2/8 is a kit of two 512m x 64-bit (4gb) ddr3-1333 cl9 sdram (synchronous dram), 1rx8, memory modules, based on eight 512m x 8-bit fbga compo- nents per module. total kit capacity is 8gb. the spds are programmed to jedec standard latency ddr3-1333 timing of 9-9-9 at 1.5v. each 240-pin dimm uses gold contact fingers. the electrical and mechanical specifications are as follows: features ? jedec standard 1.5v (1.425v ~1.575v) power supply ? vddq = 1.5v (1.425v ~ 1.575v) ? 667mhz fck for 1333mb/sec/pin ? 8 independent internal bank ? programmable cas latency: 9, 8, 7, 6 ? programmable additive latency: 0, cl - 2, or cl - 1 clock ? programmable cas write latency(cwl) = 7 (ddr3-1333) ? 8-bit pre-fetch ? burst length: 8 (interleave without any limit, sequential with starting address ?000? only), 4 with tccd = 4 which does not allow seamless read or write [either on the fly using a12 or mrs] ? bi-directional differential data strobe ? internal(self) calibration : internal self calibration through zq pin (rzq : 240 ohm 1%) ? on die termination using odt pin ? average refresh period 7.8us at lower than tcase 85c, 3.9us at 85c < tcase < 95c ? asynchronous reset ? pcb: height 1.18?
