Memory Module Specification
KVR1066D3D8R7SK2/4G
4GB (2GB 256M x 72-Bit x 2 pcs.) PC3-8500
CL7 Registered w/Parity 240-Pin DIMM Kit
DESCRIPTION:
ValueRAM's KVR1066D3D8R7SK2/4G is a kit of two 256M x 72-bit 2GB (2048MB) DDR3-1066MHz CL7 SDRAM
(Synchronous DRAM) registered w/parity, dual-rank memory modules, based on eighteen 128M x 8-bit DDR31066MHz FBGA components per module. Total kit capacity is 4GB (4096MB). Each SPD is programmed to JEDEC
standard latency 1066MHz timing of 7-7-7 at 1.5V. Each 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
533MHz fCK for 1066Mb/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) = 6(DDR3-1066)
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
PERFORMANCE:
CL(IDD) 7 cycles
Row Cycle Time (tRCmin) 50.625ns (min.)
Refresh to Active/Refresh Command Time (tRFCmin) 110ns (min.)
Row Active Time (tRASmin) 37.5ns (min.)
Power 3.195 W (operating per module)
UL Rating 94 V - 0
Operating Temperature 0o C to 85o C
Storage Temperature -55o C to +100o C
