kvr16r11d4k3/48i 48gb (16gb 2rx4 2g x 72-bit x 3 pcs.) pc3-12800 cl11 registered w/parity 240-pin dimm kit description valueram's kvr16r11d4k3/48i is a kit of three 2g x 72-bit (16gb) ddr3-1600 cl11 sdram (synchronous dram), registered w/parity, 2rx4 ecc, intel ? compatibility tested, memory modules, based on thirty-six 1g x 4-bit fbga compo- nents per module. total kit capacity is 48gb. the spds are programmed to jedec standard latency ddr3-1600 timing of 11-11-11 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) ? 800mhz fck for 1600mb/sec/pin ? 8 independent internal bank ? programmable cas latency: 11, 10, 9, 8, 7, 6 ? programmable additive latency: 0, cl - 2, or cl - 1 clock ? 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 ? on-dimm thermal sensor (grade b) ? average refresh period 7.8us at lower than tcase 85c, 3.9us at 85c < tcase < 95c ? asynchronous reset ? pcb : height 1.180? (30.00mm), double sided component *power will vary depending on the sdram and register/pll used. document no. valueram1273-001.a00 01/21/13 page 1 memory module speci cations specifications cl(idd) 11 cycles row cycle time (trcmin) 48.125ns (min.) refresh to active/refresh 260ns (min.) command time (trfcmin) row active time (trasmin) 35ns (min.) maximum operating power 6.681 w* (per module) ul rating 94 v - 0 operating temperature 0 o c to 85 o c storage temperature -55 o c to +100 o c continued >>
