Memory Module Specification
KVR1333D3D8R9S/2G
2GB 256M x 72-Bit PC3-10600 CL9 Registered w/Parity 240-Pin DIMM
DESCRIPTION:
This document describes ValueRAM's 256M x 72-bit 2GB (2048MB) DDR3-1333MHz CL9 SDRAM (Synchronous DRAM) registered w/parity, dual-rank memory module, based on eighteen 128M x 8-bit DDR3-1333MHz FBGA components. The SPD is programmed to JEDEC standard latency 1333MHz timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact fingers and requires +1.5V. The 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: 6,7,8,9,10
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
On-DIMM thermal sensor (Grade B)
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
