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

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

regardless the memory size?
i thought lower capacity is easy to reach higher...

haha..if not mistaken,the ram is micron chip

may be..but single channel is easier for sure

but the timing is

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

still early to comfirm.... the technology still new = =
micron / hynix big pontential...

elpida also not bad..hehe..1.7v+ can do ddr1500 cl7

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

the DDR 3 rams only for intel is it? still not open to AMD?? i still didnt use DDR 2.. now DDR 3 on the door step already.. haiyoh..

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

haha.. all of u USING DDR2. me, not using DDR2. hehe. haih.. with DDR3 rams.. phenom proc.. all coming in one ship. grab the wallet again...

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

haizz... u think how much the cost of 2gb ddr3? just got my new ddr2 ram and now ddr3 appears? soon ddr2 will be the rest of ddr1 loh..

w0ot.. ddr3 discussion

very fast moving liao.. ddr3 price indeed expensive

lol if not wrong i saw DDR3 price for Kingston 1GB RM700 +- wor

This post has been edited by taxidoor: Jun 26 2007, 02:05 AM

irenic paid for 2GB RM1800....

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

This post has been edited by AceCombat: Jun 24 2007, 01:16 PM

ic ic.. actually 1st i tot it was typo kingston to kiangston

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

hmm ddr3 ey? so that means it wouldn`t compatible with existing am2 or 775 lah?

So, the real word is, is there a ram manufacturer branded as kiangston or not?

Should be fake right?
Never heard of em.

lol.. no..
if got lol everywhere...

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

irenic is the only user of DDR3 in LYN right?

erk.. only him using ddr3? wah.. then maybe he can share with us about ddr3 performance.. really wanna know it from forumers, not from reviews only..

then wer is irenic..i wan to see the differnce from a forumer itself..hope he see tis thred

lol typo typo edit liao.. so far for me DDR3 is not the time yet, not bsz the price tag, is the mature of the tech

Maybe using DDR3 when AMD's socket AM3 come out.

AM2+ will be releasing soon, i dun think AM3 will release so fast....

then it would be a perfect combo between am2+ and ddr3. but sure its pricy

Unfotunately there might be no AM2+ with DDR3..

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

then i think 1333Mhz ddr3 with loose timing just on par with current 1000Mhz ddr2 tight timing.. no use to change to ddr3 except for power saving or can oc to 2000Mhz...

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

atleast it's better than 1666 with same timing..
if we can pair up with good cpu bus setting should gain better result...

as for now switching from ddr2 to high price but lower speed ddr3.. just wasting money only... since cpu speed also around 3ghz..
if everybody can affort quad core should be ok then...

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

DDR2 rated @ 1.8v and the highest rated is 2.4v. DDR3 is rated @ 1.5v so maybe 2.1v max @ 2000MHz. Is this possible?

well,who knows?maybe it is?

lol still early to say so mayb 1 or 2 year can run 1666 with 5-5-5-15 default leh who know..... another fatbody

Yes, talk bout fatbody. It has been legendary for DDR2. Which DRAM manufacturer will have legendary DDR3 chip we will know soon.

now micron chipset already run beyond 2khz

Anyway, for now DDR3 should only be used for breaking new overclocking record, since its definitely stable 1:1 for 600FSB and beyond.

what do u mean bro?

Meaning 1:1 between CPU and RAM. Let say above DDR-1200 theres no such stable module. Thats why DDR3 takes place. DDR3 can have DDR3-1333 which mean can oc up to 666Mhz FSB stable without being worry about RAM stability anymore. Sure to get that high need phase cooling though.

does ddr3 will use a different kind of slots? or it can be used with ddr2 slots?

but the latency is increased also with DDR3

although IF both had similar slot, DDR3 is most likely need different memory controller, or a memory controller that can support both DDR2/DDR3. it all depends on the memory controller, ram slot is just a slot. read the first page for your answer.

jusz like when ddr2 firstly launched... maybe few more months we'll be able to get low cl ddr3...

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

u know the price?

The problem is that DDR3 specs in terms conditions and testing are not even ratified by JEDEC yet, and the temps on it worry me man

use lower lactancy, to achive high speed, if DDR3 can do 4-4-4-4 with 1600+ speed would be nice to achieved record

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?

That's what I'm confused about. Last month someone quoted a DDR3 article which stated that it wasn't ratified by all yet. But itu temps dia...wa takut wooo

This post has been edited by almostthere: Jul 9 2007, 05:57 PM

I thought they already official until DDR3-1600.

ya that's why,we still waiting bro almostthere to make sure for us.

till tat u hv overclocked it????
hw was the temp???
will it ????

no la,it's not mine,one of the crazy ppl in the world oc his own ddr3 beyond 2000mhz.
anyway,i dont think it will be hot since it needs less vdimm than ddr2.

They only shows in Computex. No real benchmarking has been done.

no way at least not so soon

Is theoretically can achieve that point?

need to wait like a few years, but 4-4-4-4 is kinda hard..

i think the best it can reach is like 5-5-5-15..

hope to see that this ddr3 can surpass my expectation.. hopefully...

i thought high frequency need to sacrifice the timing?

DDR3 has architectural advantage over DDR2. As the time fly by and it will matures enough.

kingston is having the fastest ddr3 ram now, if i'm not wrong... ddr1333 with 7-7-7 timing (http://www.anandtech.com/memory/showdoc.aspx?i=2996)... i guess we'll pretty soon see ddr1333 with cl6 or even 5 by the end of the year or early next year... the phase of change is faster then wat we expected, the price is droping for ddr3 rams... btw, wat is BGA ram???

kingston already have ddr1375 with cl5
and tat day competition at sg,team china actually get cl5 at ddr1700+

uuuhhh... ddr1700 cl5??? dammit, that's very very fast considering most ddr2 rams can only do 1000mhz+ with cl5...

Wow...Impressive

@coolice
Do u know how much vdimm they pump and what ram they using?


-pWs-

ya coolice,can we know what is the vdim when 1700MHz with CL5?

anyway,is it the ah beng blue fancy heat spreader Hyper X from Kingston?

yes..now for sale..Rm1.3k
not sure..i will ask xu gang later

thanks bro,is he the one who did the timing and speed?

hey bro coolice,planned to get urself some highly overclockable DDR3?

1.3 k is Quite cheap for now.

rm1.3k is expensive for me

btw, BGA = Ball Grid Array

but after 2 months u go and check the price,rm1k

owh,my bad..remember wrongly..actually is ddr1600 5-7-5-x 1.9vdimm..hehe

act it's not ddr3 1375 cl5, but rated at cl7.. and everyone of us use that ram, just only xu gang manage to get a very2 good pair that manage to hit 1600 at that timing + vdimm ..

the rams that were used during competition are selling at 1.3k, but retail one is around rm1.8k as well..

i mean this
not the one we use in compy

rm1.3k does sound like a good price at least better than when it sounds rm1.8k... ddr3 is really taking really really fast pace comparing to ddr1 n ddr2... hopefully the price will become more affordable by the end of the year, like somewher around rm900 to rm1k... hehehe...

you're thinking of getting ddr3 rig by end of this year? i think i'll wait for more time..

not so sure yet but it seems like most probably that's the route to go, it'll be either by the end of the year or early next year... some pc8500 ddr2 1066MHz rams cost around rm800 now, so if the price of high performance ddr3 rams drop to dat price zone, ok mar...

i'll get myself DDR3 very soon,but i still fall in love to DDR2 now....

it's too expensive,2GB cost more than rm1k....

not only more that 1k but almost 2k lar

that y i don wan to change n patiently wait for the price to drop like ddr2

then it must a long time since ddr3 is not famous now,the performance is not mature enough....

I think it will not gonna be cheap until AMD will adopt DDR3 for its platform.

well, with the implementation of ddr3, i think i wouldn't be surprised to see fsb:dram 1:10 lol..

but the timing is keep on loosening.. ddr1 had the best timing if i can remember correctly...

Hope they can make something that have high freq, high mem, and lose timing.. will that ever be possible?

yes,DDR has tightest timing since their speed is not very high,but ddr3 now with high speed DDR1600MHZ with CL6 if not mistaken.

looks like they going to mature liao.

Quite fast mature than DDR2. Maybe that time it becoz of Netburst architecture which is not promising at all.

huh.. think of getting more time before buy ddr3.. still using ddr2 for now but planning to built new rig once after amd release its platform for ddr3

Haha..AMD Fans detected. Me too
But, i think AMD will not so early let DDR3 goes into mainstream.

-pWs-

heh, probably i'll wait til intel comes out with their own to battle amd, then i'll choose which one to side on..

For now, im happy with my rig..

but really eager to see whats ddr3 capable of..

Yes, no need to change ur rig until Penryn's out. Wait for the epic battle from Intel and AMD early next yr.

what is the suitable voltage for CL5 DDR1200?

CL5...1200.....u mean DDR3 or DDR2?

If DDR2 around 2.35 to get stable and i think DDR3 with 1.65 to 1.75 like that.

DDR1600 CL6.??? wah, so fast oredi 1600 CL6 meh??? for current c2d users, i dun think they'll be much advantage for changing to 1333fsb n ddr3 but a few more months (6 to 9 months), the trend will go toward ddr3 i guess as if the latency is tighter, with ddr1600 or highr specs then we'll difinitely see big advantage gap compare to current ddr2...

For HyperX PC9600 need how much volt? I think only 2.2V bcos if more than Kingston will use more exotic heatspreader.
