A-Data announces tri-channel DDR3 kits for Intel's Core i7
If you're thinking of carrying out a Core i7 upgrade later this year, you're probably going to want an X58 motherboard, a CPU cooler that supports socket LGA1366, and some of that tri-channel DDR3 goodness.

On the DDR3-front, some of the first tri-channel kits to be branded as "ready for X58 motherboards" have come from Taiwan-based A-Data.

It's today announcing production of DDR3 1600 and DDR 1333 tri-channel kits in 3GB and 6GB capacities. It expects availability in this quarter, with prices starting from $230.

The DDR 1600Mhz kit has been tested in tri-channel configuration with latency settings of 8-8-8-24 2T. The 1333MHz kit has been verified at 7-7-7-20 2T.

A-Data's recommended retail price for the quicker DDR3 1600 kits is $230 for the 3GB model (3x1GB) and $350 for the 6GB model (3x2GB).

Not bad, I was budgeting more for 6GB kit.

How come the future offers less for more cash :P i like 8GB kits.

Intel's Core i7 requires tri-channel DDR3 kits.
Yours is DDR2 Dual Kit memory plus since the tri-channel kits are new on the market they will cost more to start with.

i7 does not require tri-channel memory, only if you want to take advantage of triple channel, still works with dual channel.

That's a lot of unnecessary bandwidth. :lol:

does the tri memory thing bring anything to the table in terms of real performance -.-...

Probably in very specific situations, but I doubt it'll do anything for gaming. Especially vs. dual channel DDR3. 800Mhz dual channel memory isn't a bottleneck in gaming, so 1600Mhz dual channel definitely won't be.

Are you sure? But what if you put 4 in? I read it doesn't work like that. Is it only with motherboards with 4 DIMM's ( 3+1 ) and not the case with 6 DIMM's (3+3)?

In a meeting between Legit Reviews and Intel it was discovered that three slots should be used if you want the best performance. If you pop in a fourth module and occupy all the slots the DX58SO motherboard won't be running in quad-channel. It will actually default back down to single channel mode, which will obviously drastically impact memory bandwidth. The official support memory clock speed is 1066MHz, but Intel was quick to say that 1333MHz, 1600MHz and even 2000MHz memory kits will work on the platform.

I wonder if the memory manufacturers will go past 1.65 volts, there are a lot of kits in the 2.0v range now. Should get interesting...

yes. it most definitely does not require triple channel kits.

so will any boards feature DDR2 support? or will this be true intel fashion and adopt DDR3 right from the start?

I'm sure gaming won't be affected as much as some other apps.

Remember the transition from AMD socket 754 to 939? The increased memory bandwidth gave better gains in synthetic benches more than real world gaming performance.

Probably not because Nehalem has an integrated memory controller.

ahh yes. almost forgot.

Aww, I wish I had money for Nehalem. :( Going to stick with DDR2 for now....

im content with my C2D setup. i might go quad, but i wont go for Nehalem for at least another year.

I am currently with a quad. Q6600 is a sweet processor, even at stock. Q6600 coupled with my upcoming GTX260 should last for a while. I don't usually update to the latest-and-greatest anyway. No monies. :p

Yes it will even manage to run on single DIMM same like the Dual Memory mobos do but I don't think many people have such setup. I probably should have specified the triple channel advantage.

Anyway my reply was directly to -=DVS=- post
How come the future offers less for more cash :P i like 8GB kits.The 8GB DDR2 kits he likes in his signature are useless for i7.
The i7 has "Integrated 3 Channel DDR3 Memory Controller "

In the third quarter 2009 Intel will release MAINSTREAM desktop Nehalem (Lynnfield) with true support to Dual-Channel DDR3 memory and again new socket LGA 1160.

I sure won't buy anything else than optimized Tri-Channel DDR3 kits when upgrading to X58 mobo that supports socked LGA 1366.

The rumors are: According to Intel CPU SPEC, DIMMS with voltage setting over 1.65v may damage the CPU permanently. The picture is from Xfastest.com (http://www.xfastest.com/redirect.php?tid=14549&goto=newpost)

That's why the RAM vendors are tweaking the kits to run higher speed with less voltage.
The A-Data Tri-Channel kits subject of this thread is already pushing it with the up to 1.75V specification but since they offer "Lifetime limited warranty" I believe they must have been tested as such.

Here are the A-Data kit specifications and futures as listed at hexus.net (http://www.hexus.net//content/item.php?item=15741)
Specification:

1. DDR3-1600+ & 1333+ 3GB/6GB tri-channel module kits are tested at 1600MHz/1333MHz

2. Test in tri-channel configuration at latency settings 8-8-8-24 2T for DDR3-1600+ and 7-7-7-20 2T for DDR3-1333+ at 1.65V-1.75V

3. SPD (Serial Presence Detect) programmed at JEDEC standard for basic system booting

Features:

1. All memory chips are verified using overclocking criteria for better quality

2. High quality 6 layers PCB (Printed Circuit Board)

3. Optimized for 64-bit OS (operating system)*

4. Backward compatible with DDR3-1333, 1066

5. Lifetime limited warranty

I might replace my motherboard with something more overclockable, get water cooling and go with a newer video card. I'm not getting a new processor anytime soon though.

get a DFI board. theyre more expensive, but they are worth the money.

I'm happy with the Biostar. It's the P43 that hits a limit at around 420mhz. My board also doesn't have great CPU voltage adjustment compared to their P45 model. If I knew this, I would have gotten a better model. I just got the one it, so it will be a while before I upgrade again. I believe that almost 3.4ghz on a Quad is good enough for a while too.

I've already got a 4Gb (2x2Gb) DDR 3 1600 kit. I am guessing as long as I bought another 2Gb stick rated at the same speed and timings by the same company I should be gtg.

That's my point downgrading ram capacity for extra bandwidth is hardly innovative improvement , they break rule of 2 we don't have 1.5 gig ram sticks.
Anyways seeing you motherboard picture in second post , upgrade path for me would be to go with 12 gigs of DDR3 , going to 6 gigs feels downgrade not upgrade :p Hopefully they support more then 8 gigs , current motherboards max is 8 sadly except few older nforce MBs.

The voltage recommendation/limitation is not for the memory, it's for the CPU with the IMC. I guess the RAM's lifetime warranty won't cover damaged CPU ;)

The way I see it.
The Tri-channel kits are ONLY for the x58 mobo and the i7 (Bloomfield) CPU. If the advertized voltage rating would start damaging the CPU they soon would have class lawsuit on their hands.

After all here are some off the specs they advertize

1. DDR3-1600+ & 1333+ 3GB/6GB tri-channel module kits are tested at 1600MHz/1333MHz
2. Test in tri-channel configuration at latency settings 8-8-8-24 2T for DDR3-1600+ and 7-7-7-20 2T for DDR3-1333+ at 1.65V-1.75V

Features

1. All memory chips are verified using overclocking criteria for better quality

All I can say they better be right and the same goes for every RAM vendor coming up with the new Tri-channel kits optimized for the use with the i7 Integrated 3 Channel DDR3 Memory Controller.

I wonder what voltage was used for the over 2000MHz overclock. Anyway it looks like pretty good bundle even more so if the pretty girl is included.
A-DATA and ASUS Demonstrate Intel Nehalem's DDR3 Performance
Remember the A-DATA DDR3 triple channel memory and the ASUS P6T Deluxe motherboard? They are both detailed on our page, but this story aims to show how both parts perform when working coupled with a quad-core Core i7 engineering sample CPU. The results you're about to see below are achieved by three 1600MHz A-DATAs overclocked to over 2000MHz. The result is system memory read/write speeds of up to the incredible 20515/16946 MB/s. The latency time is also worth mentioning - 22.9ns techPowerUp (http://www.techpowerup.com/73397/A-DATA_and_ASUS_Demonstrate_Intel_Nehalem_s_DDR3_Per formance.html)
