Detail Description:

1) DDRII 533/667/800 MHz

2) 168/184/240-pin socket type dual in line memory module (DIMM)

3) 2.6V power supply

4) Data rate: 533/667/800Mbps (max.)

5) 2.5 V (SSTL-2 compatible) I/O for DDR I products,1.8Vpower supply for DDR II products

6) Double-data-rate architecture, two data transfers per clock cycle

7) Bi-directional, differential data strobe (DQS) is transmitted/received with data, to be used in capturing data at the receiver

8) Data inputs and outputs are synchronized with DQS

9) DQS is edge aligned with data for read, center aligned with data for write

10) Differential clock inputs (CK and CK)

11) DLL aligns DQ and DQS transitions with CK transitions

12) Commands entered on each positive CK edge: data and data mask referenced to both edges of DQS

13) Four internal banks for concurrent operation (component)

14) Data mask(DM) for write data

15) Auto precharge option for each burst access

16) Programmable burst length: 2, 4, 8

17) Programmable/CAS latency (CL): 3

18) Programmable output driver strength: normal/weak

19) Refresh cycles: (8192 refresh cycles/64ms)

20) 7.8US maximum average periodic refresh interval

21) Posted CAS by programmable additive latency for better command and data bus efficiency

22) Off-chip-driver impedance adjustment and on-die-termination for better signal quality

23) DQS can be disabled for single-ended data strobe operation

24) 2 variations of refresh

25) Auto refresh

26) Self refresh

Our Services

1. Poor contact

Remove the memory, wipe the golden finger with eraser. then put into the motherboard to further check. If still does not work after memory been wiped for times and memory slop replaced. the momory should be deffective in this case then. You can take another memory stick to try again, or put the memory into another motherboard to further test.

2. Boot up failure

Turn off the computer, check the memory carefully to see if any defect on surface like golden finger, chips and boards, If no damage found. then should be install issue. So take out the momory. wipe the golden finger with eraser or alcohol carefully. after the alcohol evaporate, put the memory into the slot correctly. Also the defected memory slot will aslo lead to boot up failure.

3. Windows often switched to safe mode automatically

Mainly because the motherboards and memory are not compatible, high frequency of the memory does not support on the motherboards, should try to slow down the written speed in the CMOS. if still does not work. then plese replace the memory.

4. Computer random crash

Mainly as a result of the adoption of different chips of memory, the speed of memory differences a time lead to the crash, this can be solved in the CMOS setup by reducing the memory speed, otherwise, can only use the same memory. Another possibility is memory do not compatible with the mainboard,this rarely happens. poor contact also might lead to random crash.

5. High temperature on the memory

Under this condition. you can add a fan in it to improve the air flowing. Or you can add aluminium or cooper heatsink on the memory for better heat dissipation.
