Hot news. DDR3 memory modules is out!!

Reviews so far:

Super talent DDR3 - working modules
Buffalo DDR3 - already for sale!
Anandtech : DDR3 vs DDR2
Kingston DDR3 vs DDR2
AnandTech: Intel P35
First low-latency DDR3 - Kingston
---DDR3-1066 (6-6-6)
---DDR3-1333 (7-7-7)
Corsair Dominator at 1600 Mhz (and preview at 2000Mhz)!!
X-bitlabs - DDR3 SDRAM
OCZ DDR3-1800
OCZ platinum vs Corsair Dominator DDR3-1800

More info on DDR3:
Samsung's DDR3 info

Facts up to now:

90 nm process
40% lower power consumption (compared to DDR2)
1.5V (DDR2 1.8v, DDR 2.5v)
800-1600 Mhz effective clock rate (DDR2 : 400-1066 Mhz) (DDR 200-600 Mhz)
CAS 7 (Rated at 5 - 10) (DDR2 3-6)
8-bit pre-fetch architecture (DDR2 4-bit)

Mainstream in 2009 (Probably..... maybe..... don't get your hopes up to much!!!)

And the last part:

240-pin DIMM interface - allowing DDR3-compatible chipsets to host DDR2 modules !!!
Update : Misleading - DDR3 has different notch compared to DDR2!

This means that by that time, when we upgrade, we can still use our DDR2-1200 Mhz CL 3 Corsair dominator water-cooled RAMS !!!

Attached is the DDR3 speeds as compared to DDR2. Due to no speed advantage, it is said that AMD would not transition to DDR3 until at least DDR3-1333.....

Isn't super talent a good U.S brand?

Frankly speaking, I've never heard of this brand until I saw our nice LYN traders selling it individually or in bulk.

I don't think DDR2 will be discontinued anytime soon. Same thing happened last time when DDR2-533 and DDR2-667 came out and reviews showed that DDR2 did not have much speed advantage compared to low latency DDR400 rams.

Facts on DDR3 from Wiki:

90 nm process
40% lower power consumption (compared to DDR2)
1.5V (DDR2 1.8v, DDR 2.5v)
Effective clock rate 800-1600 Mhz (DDR2 : 400-1066 Mhz) (DDR 200-600 Mhz)

And the last part:

240-pin DIMM interface - allowing DDR3-compatible chipsets to host DDR2 modules !!!

This means that by that time, when we upgrade, we can still use our DDR2-1200 Mhz CL 3 Corsair dominator water-cooled RAMS !!!

Err.... the hyperlink above on Buffalo DDR3 indicates that its DDR3 will be CAS 7!!!
(DDR3 CAS 5 to 10) (DDR2 CAS 3-6)

But even CL7, supposed to be faster.....

Probably burn 8 holes, rather, as it is reported that initial DDR3 memory modules will be 8x more expensive!!!

Ya lo. I guess it will slowly come down to CL6 then CL5. Like DDR2......

Going to miss those days where CL2.0 was such a thrill to aim for!!!!

I also don't think so as DDR3 mobos is supposed to be able to support DDR2. A lot of people would probably use the DDR2 rams when they upgrade (especially those with good DDR2 modules e.g. corsair dominator )

Some reports indicate that it will become mainstream in 2009 (probably not, considering the track records of new computer hardware/software).

I'm also using DDR, hmmmmm..... wonder whether we can streeeeettccchhhhh the life of our current rig, wait a bit longer, and jump straight into DDR3 and skip DDR2 altogether!!!! LOL

DDR3 RAM has been released! Read the hyperlink on the first page on "Buffalo RAMs".

Wonder who would buy it......

Oh no! I didn't believe that until I googled it. It seems that it is true the notch is in a different place.

How misleading this phrase is - "240-pin DIMM interface - allowing DDR3-compatible chipsets to host DDR2 modules !!!"

Note the word "chipset". It actually (cleverly) didn't mention anything about DIMM compatibility!!! Only chipset compatible!

Hopefully, there will be DDR3 mobo that have slots for DDR2 DIMM???!!??!?

Hopefully there is. However, some people might not like it as they won't be able to use the full 4 slots if they decide to later upgrade totally to DDR3.

As for me, I don't mind using only 2 slots as I still want dual-channel!

Unless DDR3 mobo can have quad-channel????

Here's a comparison between DDR3 vs DDR2.

Just look at the DDR3 timings!!

Wei, no ranting here. Can go to "Kopitiam" to rant.

OIC. +1

Well, I guess companies are competing to get their DDR3 modules out. You know how competition is. It is true that the industry is not ready for DDR3 yet but I guess you have to start sometime!!!

The good news is that at least DDR3 outperforms DDR2 on intro!! If you compare this to the time when DDR2 initially came out, recall that reviews showed DDR2 inferior to DDR!!!

Nobody in his/her right mind would buy DDR3 + DDR3 mobo now (unless you have money to throw away!). It is possible/probable that the technology is rolled out now so that tech ethusiasts can test them and iron out all the bugs. Remember that labs testing and real-world testing are two complete different scenario. Their modules can be 100% compliant in the lab but when used in real-world condition, found to have many bugs. This is the time for DDR3 to mature!!!!

The same can be said about Vista. Who needs vista now? So many bugs and problems......

DDR3 has arrived and won't be mainstream probably until late 2008 or early 2009. Until then, more companies would have rolled out their products and definitely prices will drop. As for myself, I wait for DDR3 + Quad-core (8-core???) + "matured" vista with open arms!!!

Ya, and their conclusion is "Cette dernière en DDR2-1066 parvient même à se placer devant la DDR3-1333". ????

Sorry la, I only speak English! LOL! Better wait for the English version.

What language is this anyway?

Eh, I thought in previous reviews, DDR3 ram did beat DDR2? Any new reviews in English to confirm this?

I did see the review on TomsHardware. However, halfway thru I was already getting a heache as there were so much information! Not to mention new product names like P35, G33, X38.....

For example "First of all, Intel releases the P35 (mainstream) and the G33 (mainstream with integrated GMA 3100 graphics). The faster G35 and the enthusiast version X38 (PCI Express 2.0) will follow in Q3. Both P35 and G33 carry a DDR3 as well as a DDR2 memory controller." I'm sure this has to be read a couple of times before it is understood!!!

Low-latency DDR3 from Kingston has arrived!!!

Current DDR3-1333 (9-9-9) : Kingstons DDR3-1333 (7-7-7)
Current DDR3-1066 (7-7-7) : Kingstons DDR3-1066 (6-6-6)

Read the review here!

Yup. Still have to wait for it to mature and the prices to come down.

However, it is exciting to know that even now, DDR3 RAMs can go up to 2000 Mhz!!! Courtesy of Corsair!! (Hyperlinks in the first page....)

Here a new review on DDR3 : http://www.xbitlabs.com/articles/memory/di...r3_2.html#sect0

Answers a lot of questions including projected lifespan of DDR2 and DDR3!!

Yeah, that's right! Because DDR4 is projected to arrive in 2011!
