  Deneb to support both AM2+ and AM3?

Ok, I've been reading around and came to the conclusion that I am greatly confused.

On one front, people say that a single "Deneb" processor can be put in either a AM2+ or AM3 board and work with either DDR2 or DDR3 due to both memory controllers being on the processor.

On the other hand, people say you can only buy a "Deneb" processor either for AM2+ or AM3. But it will only fit into the board that you buy it for. (Therefore having either a AM2+ version Deneb or AM3 version)

My Question? Which one it true? Anyone care to shed some light?

Thanks :)

Every credible report I've read supports this version. Although to be somewhat pedantic about it, I believe there is only a single memory controller, that is compatible with either DDR2 or DDR3 (same number of pins in both standards).

realistically, I would have to believe that there would be only one controller and that either you go with DDR2 or DDR3 and the motherboard that would support one or the other... not both..

If you take a look at the AMD roadmap (sorry don't have a link, I'll have to try finding it) It lists the different versions of processors.

Which upon looking closely, there are 2 versions that support AM2+, and the rest support AM3....... so I'm leaning towards Deneb only supporting one the type of ram it is designed for.

Although I HOPE I am wrong. :)

here is a link to a preview of Deneb.... it is google translated to english from Chinese... kinda funny reading it because of the translation

http://translate.google.com/translate?u=http%3A%2F%2Fwww.hards...&tl=en

looks like going to 45nm process will be good for AMD as it shows very good power reduction.

Yea, I read that a while ago. That's why I wondering on my question. If all goes right, I might be trading my rig for a 780G motherboard and a brisbane to hold til these come out! :)

Then once they do, I'll just grab one of them which hopefully will be able to to go to an AM3 motherboard with me later on.

Mark,

even that website's preview is un-sure about the support of both DDR2 and DDR3 at the same time..... you will only know for sure when it is actually out officially.... or at least by when they do the NDA release date and all the review sites with have official reviews out. But one can hope, like yourself...... buy a Deneb now for your current mb using DDR2 and then later swap out the mb to use DDR3.

On the Intel side, GIGABYTE has mb for the p45, p38, and p35 chipset that supports DDR2 and DDR3 (not at the same time) on the same mb.... BUT... that's because the mem controller is off board from the cpu and in the chipset..... I think when it comes to onboard mem controller within the cpu... that is going to be a different story and more complicated... I'm still thinking that Deneb will have two versions, one to support DDR2 and one to support DDR3... But you know.... anything can happen as time goes along.

Yea, I'm thinking it will have 2 versions too. Oh well, I had really wanted to future proof my system. But I might as well stay with my current build and just upgrade to quad for my final upgrade.....

I think it will be one of two things...

1) The chips will have both DDR2 and DDR3 memory controllers integrated into the processor die but they will only wire one of them up. That way they don't have to do much retooling and can offer DDR2 and DDR3 versions of the processor.

2) It is solely DDR2. DDR3 is still quite expensive and that isn't going to change right away with Nehalem's launch. AMD is only making money in the cheaper stuff which means steering clear of DDR3 for the near future.

3) It is solely DDR2. JEDEC wants to phase out DDR2 memory so Intel and AMD move to DDR3 together with Nehalem and Deneb, respectively. I think this is the most likely scenario.

I heard the Q4 2008 Deneb's (2 of them at 2.8 GHz & 3.0 GHz) will have a DDR2 & DDR3 memory controller with DDR3 turned off.
After these two CPU's are released, the others will have both DDR2 & DDR3 enabled on the CPU's with the motherboards North Bridge controlling which one to activate.

Personally I would rather stick with a good AM2+ platform and buy up some nice cheap priced DDR2 memory. DDR3 is still way to expensive. Then just pick up a AM3 CPU or a newer 45nm AM2+ based CPU. How does DDR2-1066 w/ 16GB (4GB x 4) sound 8) 8)
