Quad channel ram

[Tuffrabbit]

Saw this in GURU 3D... Quote; "The QPI architecture allows Intel to connect tri- or even quad-channel memory directly to the the processor's integrated memory controller"...
Anyone think this might be forthcoming ?

quad could work if they wont make RAM sticks larger than 2GB. 6-8GB of ram is getting quite common. but i dont think it'll bring any performance advantages, just like tri-channel doesnt do much today.

Seconded. DDR3 is so fast in comparison to the other components of our systems that it'll be awhile before dual channel, never mind triple channel, RAM is a bottleneck on the consumer side of things.

True. But if quad channel memory makes board makers to put 8 dimm slots on their boards (like most 1366 boards with six dimm's), then I am all for it.

I could have sworn that RAM was still one of the slowest components in our computers. (hard drives being the absolute slowest, especially mechanical hard drives)

s2011 is designed for quad channel. Yes, 8 slots should be the "standard" setup. Thats only 32-64GB of memory per socket, and s2011 is designed around/for dual socket mobos.

There will come a high end "Sandy Brigde" with quad-channel RAM sometime in 2011.

But it's RAM latency, not bandwidth, that is the main factor.

There's not enough room for 8 dimm slots in an ATX formfactor though, so that would mean you'd need an EATX board.

not only that, but with that much real estate devoted to RAM slots, there's not going to be a lot of room for mosfets, caps, other power filtering components. Which means diminished OCing, which means server boards.

They could still do four slots with quad channel. Personally, I'd be happy with 16GB of quad channel DDR3 1600.

EDIT: What I'm saying is s2011 is gonna be server (2P/4P only)

and they bump up the latency every time they increase the speed, which negates any latency gains

i miss RDRAM

 

[dorion]

If were running quad channel do we really need 8 dimm slots? I'm still very much wanting to give a board like this one a go http://www.newegg.com/Product/Produc...82E16813186171.

Seeing how little triple does over double...why even bother?

 

[God Mode]

They should just make ram into ssd or smaller sized modules that plug into a slot on the motherboard. Take the same space as a half height to full height card. Everything about current consumer atx boards scream legacy and inefficient layout unless you have a custom board made.

Because tripple channel dosn't go well at +6 cores, that is with the octo-cores will have qualchannel.
It's a matter of bandwith per core.

I don't think so. My understanding was that s2011 is was both entry-level server and enthusiast for SB. I believe this socket will be used in the X68 (if that is what it will be called) chipset middle of 2011. Unless someone else has different thoughts.

That's my understanding as well. Socket 2011 will serve the same purpose that 1366 serves now.

damn, i meant to stick a mostly/probably in there. It's probably going to be just like 1366. Server socket (because of all the added IO pins from the processor) with some "shits and giggles" sales for enthusiasts. I wonder how much of a premium intel is going to charge for being so far past overkill for an enthusiast he can't even see the other side. No wonder x58 was never really a success (according to intel)

According to this article, LGA2011 will only support 1 slot per channel (4 slots total, not 8): http://www.bit-tech.net/hardware/memory/2010/08/26/ddr4-what-we-can-expect/2

So it appears we will not need larger MBs.

I guess with 4GB dimm's so cheap, it doesn't matter. Saw some yesterday for ~75.

finally, they were stupidly expensive last year for no reasonable reason.

Maybe someday 4GB DIMMs will be affordable?
With this configuration, the ideal setup would be 4x1GB, 4x2GB, or 4x4GB. The 8GB option will probably become the defacto standard for a while.

I was selling a lot of systems with 4x2GB when 2GB DDR2 modules were running <$20. Less than $100 for 8GB, it was a no-brainer. I was buying memory by the box.

I don't think Intel will release it as an enthusiast platform unless BD does really well, and they need a faster platform on the client side to compete. If that doesn't happen, I don't see it being cost effective for them to release a s2011 platform for enthusiasts.

Yeah, the "good old days".

I remember feeling like I was "paying through the nose" at $199 for my 6GB kit in 11/2008 for my new i7 build. You could get a 8GB kit at that time for about $110-120, but it was DDR2. At least DDR3 prices have started to come down again. I am hoping Q2/Q3 next year will be ideal prices around the time I plan to build a new system.
