New Low Voltage Standard DDR3 Passed by JEDEC.

DDR3L to Work at 1.35V


with all the hype around videocards at the moment, kinda hard to notice that theres some interesting stuff happening in ram too.

new low power DDR3L...

wonder when we will see these start popping up.
hopefully at a decent speed.
none of this ridiculous 1066 at cas 9-9-9 stuff.

who knows. but it is interesting.

Improvements in silicon production processes have enabled a reduction in the core and I/O voltage for an incremental improvement in DDR3. Called “DDR3L” for Low Voltage, the new devices will operate from a single 1.35V rail, compared to the 1.5V of existing devices, resulting in a power savings of 20% in many mainstream applications.

anyone know what happened in previous times when they lowered voltage? higher speeds? lower clocks? please god let CL6 DDR3 2000 be affordable...

Interesting... I keep wanting to switch to DDR3 but it would entail a new motherboard and the RAM is rather pricey at the moment... I so wish I had caught the $50 after $150 rebate deal for a few gigs :(, it was CL7 stuff too. 1600mhz 2x1GB kit :( /cry.

Power savings? In RAM? Who cares? Sucking down 7 watts must break a lot of people's power bills, eh?

Lower voltage means less heat.

Some agencies have clusters with 20TB of RAM in it , it does matter.

I wonder how many of the current desktop boards support this. I pressume that at the very least the BIOS needs to be updated.

Laptops? Heat=Noise? Also yes, it does break the powerbill when volume goes up if you look on amounts. 1W saving could easily be 1million W saved in NY etc.

I think that now we will see new Kit DDR3 4GB too.

GB

this is bad this means that high performance wont be out for most desktop platforms so if u want to oc it might break the chips to use proper voltage, or it could just under rate good ics to start

No. It means that yields for DDR3 are great all accross the board. This is good news for overclockers.

True enough.

well historically a higher clock speed. [Because limiting factors for clock speed are trace lengths, power and thermal envelopes]

Well I guess some of the rumors that Nehalem can't handle high RAM voltages could be right. This is a way to go round it. I for one hope that 1600DDR3 will be feasible on the new platform when it starts, that would be enough imo...

No, this has to do with things like laptops.

You never know. Sometimes things are not black and white. The main thing could be laptop memory but this could also mean that there will be some low voltage sticks developed for desktop use. There is nothing wrong with this either way.

Definitely, low-power DIMMs are needed for DDR3 in servers and laptops. Even a 1W savings in a laptop will give 1-3% better battery life in low-power notebooks. For UMPCs, that's GIGANTIC news.

I would rather like to see a shrink in the fabrication process from 90nm down to 78/70 nm or whatever before they bring down the voltage. Voltage is not the only dimension/parameter in heat dissipation. It is ONE of them. So I would have to see a shrink in the fabrication process and/or some architectural changes to reduce the leakage(Prescott to Conroe anyone), before I jump up and down.The die shrink would also drive down the costs.

If there is for desktops I would buy them. :p:

from what I can remember at IDF slide shows it is their goal to lower the voltage every succeeding year or increase the frequency at the same voltage
so I think this covers all the RAM modules from Server,Desktops and laptops

This was in Micron marketing sheets - more speed, less power.
Lets hope there will me motherboards/bios supporting this not only in notebooks, but also in desktops. DDR2 1066MHz was JEDEC approved too, even if you make proper SPD for that, only very few boards read it properly.

How much voltage are 1600 DDR3's sucking down now?
Are we still at 1.5v for CAS9? And where are we for tighter timings...

I love this news for lower voltage, though...

Great for ultramobiles. Some day it'll all add up to have an 'Eee' like device running on wi-fi all day untethered..

Geil has some that are rated to do 7-7-7 1600 at 1,7V, but of course that has nothing to do with jedec specs.
