Kingston HyperX Blu DDR3 1600 PC3-12800 4GB 2x2GB CL9 

Kingston´s KHX1600C9D3B1K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR3-1600MHz CL9 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR3 FBGA components per module. Total kit capacity is 4GB. Each module kit has been tested to run at DDR3-1600MHz at a low latency timing of 9-9-9-27 at 1.7V to 1.9V. 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 JEDEC standard electrical and mechanical specifications are as follows:

Features:

• JEDEC standard 1.5V ± 0.075V Power Supply
• VDDQ = 1.5V ± 0.075V
• 667MHz fCK for 1333Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 5,6,7,8,9,10
• Posted CAS
• 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 then TCASE 85°C, 3.9us at 85°C < TCASE . 95°C
• Asynchronous Reset
• PCB : Height 1.180” (30.00mm), double sided component 

Performance:

• CL(IDD) 9 cycles
• Row Cycle Time (tRCmin) 49.5ns (min.)
• Refresh to Active/Refresh Command Time (tRFCmin) 110ns
• Row Active Time (tRASmin) 36ns (min.)
• Power 1.800 W (operating per module)
• UL Rating 94 V - 0
• Operating Temperature 0o C to 85o C
• Storage Temperature -55o C to +100o C
