computer components from china ddr2 ram

DDR2 ram 2gb work with all motherboard

1.original ic ,good quality, original 800MHZ . 
2. stock goods. can send it at any time.
3. all be tested before sending . tested by memtest professional software
4. all 2GB is made by 128* 8 ic , total 16 ic . 8 bit ones.
5. can fit for any mothebroard ,. never choose motherboard .
6.1 year warranty  and if have bad ones send to us directly , and   we will change all new ones for you.

Detail Description:
1) DDR 400/333 & DDRII 533/667/800 & DDR3/1066/1333/1600 MHz.
2) 168/184/240-pin socket type dual in line memory module (DIMM) .
3) 2.6V power supply
4) Data rate: 400/333/533/667/800M1066/1333MHZ/1600mhz (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 synchronzed 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
