512M x 64-bit (4GB)DDR3-1333 CL9 SDRAM (Synchronous DRAM), 2Rx8 memory module, based on sixteen 256M x8-bit DDR3-1333 FBGA components. The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact fingers.

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 85°C,3.9us at 85°C < TCASE < 95°C

Asynchronous ResetPCB: Height 1.18" (30mm)/Height 0.740" (18.75mm), single/double sided component
