Hi,AceCombat on the line,let me start this topic and discuss everything about DDR3 over here.

What is DDR3?

DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is the name of the new DDR memory standard that has been developed as the successor to DDR2 SDRAM.

The memory comes with a promise of a power consumption reduction of 40% compared to current commercial DDR2 modules, due to DDR3's 90 nm fabrication technology, allowing for lower operating currents and voltages (1.5 V, compared to DDR2's 1.8 V or DDR's 2.5 V). "Dual-gate" transistors will be used to reduce leakage of current.

DDR3's prefetch buffer width is 8 bit, whereas DDR2's is 4 bit, and DDR's is 2 bit.

Theoretically, these modules could transfer data at the effective clockrate of 800-1600MHz (for a single clock bandwidth of 400-800MHz), compared to DDR2's current range of 400-1066 MHz (200-533 MHz) or DDR's range of 200-600 MHz (100-300 MHz). To date, such bandwidth requirements have been mainly on the graphics market, where fast transfer of information between framebuffers is required.

Prototypes were announced in early 2005, while the DDR3 specification is expected to be publicly available in mid-2007. Supposedly, Intel has preliminarily announced that they expect to be able to offer support for it in mid 2007 with a version of their upcoming Bearlake chipset. AMD's roadmap indicates their own adoption of DDR3 to come in 2008.

DDR3 DIMMs have 240 pins, the same number as DDR2; however, the DIMMs are physically incompatible, owing to a different key notch location. [1]

Features From new generation ram

DDR3 SDRAM Components:
Introduction of asynchronous RESET pin
Support of system level flight time compensation
On-DIMM Mirror friendly DRAM ballout
Introduction of CWL (CAS Write Latency) per speed bin
On-die IO calibration engine
READ and WRITE calibration

DDR3 Modules:
Fly-by command/address/control bus with On-DIMM termination
High precision calibration resistors

Advantages compared to DDR2
Higher bandwidth (up to 1600 MHz)
Performance increase at low power
Longer battery life in laptops
Enhanced low power features and thermal design

Disadvantages compared to DDR2
Commonly higher CAS Latency
Lower MFIBS per Quad Cycle

Built-In DDR3(Currently only one motherboard using )

Asus P5K3 Premium
Built in 2 GB of DDR3 rated at 1333MHz,can be overclocked to 1600MHz,it uses Qimonda Chipset,size is only 3 quarter of a real DDR3!!!!

Reserved for future

eh....
haha.....didnt update yet,thanks for the source bro coolice,updating.....

but the timing is

Added on June 22, 2007, 4:30 pmlooks like Micron is going to be the legendary overlcockable chipset again....

aiyo....now is still too early to make sure which are good mah......

bro,all of us still using ddr2,if not mistaken,irenic is the only one who using ddr3....

suppose to be X38,45nm,DDR3,SLi 8950GTX,2KW psu.

irenic paid for 2GB RM1800....

bro taxidoor,Kiangston and Kingston not same,one is branded,one is chapalang.

actually...........I KNOW it's typo.
but i joking only la....

bro shawty,of course there is no kiangston around la....

irenic is the only user of DDR3 in LYN right?

AMD is using same memory controller,then the DDR3 loose timing will kill the performance.

but when u oc to 2000mhz it will be around 10-10-10-20 like that or maybe looser than thatt

ya lo....but for intel cl10 i think ok la....but AM3 with integrated memory controller,it must be very "cute"

well,who knows?maybe it is?

now micron chipset already run beyond 2khz

what do u mean bro?

that is for those super crazy to buy....
anyway,if 1600MHz can run with CL7,then it's nice bro.

u know the price?

bro,sacrification is a must,i think it is impossible to hit 2000Mhz with 4-4-4-x,right?

if u wan hihg speed,the timing must be loosen,if u wan tight timing,then u will have lower frequency...

bro almostthere,if not approved by JEDEC,then how come we can find the spec at the website already?
