ValueRAM’s KVR18R13S8/4 is a 512M x 72-bit (4GB) 
DDR3-1866 CL13 SDRAM (Synchronous DRAM), registered 
with parity, 1Rx8, ECC, memory module, based on nine 512M x 
8-bit FBGA components. The SPD is programed to JEDEC 
standard latency DDR3-1866 13-13-13 at 1.5V. This 240-pin 
DIMM uses gold contact fingers. The JEDEC standard electrical 
and mechanical specifications are as follows: 

• JEDEC  standard 1.5V (1.425V ~ 1.575V) Power Supply

• VDDQ = 1.5V (1.425V ~ 1.575V)

• 933MHz fCK for 1866Mb/sec/pin

• 8 independent internal banks

• Programmable CAS latency: 13, 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 85°C,
  3.9us at 85°C < TCASE < 95°Cº

• Asynchronous Reset

• PCB: Height 1.180” (30.00mm), double sided component
