Have I missed Something - DDR3 CPU?

I think this is actually right - as far as I understood previously AMD are skipping DDR2 completely and moving to DDR3 with M2 chipset

Might be getting mixed up however
 
well i cant see ddr3 being implemented? as we dont have any actuall ram that has ddr3 memory chips yet.
is it possible for AMD to do both? as in a controller which supports ddr2 and 3? :confused:

Not S939 replacement (AM2, previously known as the M2) will use DDR2.... but thats only a 940pin socket.
The 1207pin is the server side version. I've not seen any DDR3 memory, or it commented anywhere else. Maybe it just supports DDR3 but wont actually use it until (obviously) the mobos and ram comes out?
 
That's how it reads yeah. It's a little unclear, at least for me. IT doesnt make sense to me because servers traditionally require registered and buffered ram. Moving to a completely new platform for the ram when we know very little about its long term stability (DDR3) is either very stupid or they know something we dont.


The last thing you want to do as a company is bring out a server line that doesnt perform because of memory errors.

was rambus technology ever used in intell servers? as DDR2 and DDR3 memory is just rambus technology hybridised with DDR

and i dont really see any reason why DDR3 coudlnt juse the same socket at DDR2

and you're forgetting that DDR3 memory is available for graphics cards, it's jsut a case of taking the chips from the cards and putting them on a memory module :p

Edit: thinking about it though... quad core would be pretty dman cool, they could up the processors to 16-way and have 16 physical cores on one server, i say put SLi or crossfire on it too and then bench it!

This is exactly why I was thinking they were testing the uncertain DDR3 on the desktop M2 / AM2 chipset.

Goksly - not meaning to critisize or nowt, you are right I had heard they are moving back to S940 (even though its a different config to original s940) but the new socket IS a replacement for the desktop is it not?

As I am understanding it:

S939 >>> AM2 ( variant of S940)
S940 (original)>>>(S1207)

Maybe thats it - a tried and tested DDR2 ( which should be getting cheaper also due to necessary ramping up of production) is positioned as desktop ram on AM2

DDR3 - which requires ECC for the moment due to being relatively untested etc is positioned for Server market place ie S1207

Intel a few years back came out with a mobo or maybe just chipset that could use two different types of ram ( was it SDR and DDR?) , could this be a possible avenue for AMD?

actually the whole DDR3 thing started off as a rumor and got shot down a month or two back... i think it was actually theinquirer that did the artical that said the DDR3 rumor was false as well :confused:
 
FrankJH -> No offence taken etc :}
What I was trying to get across (although not very well I admit) was the article im refering to is 1207pin (server) which is the upgrade from 940pin. Now, as AMD have proved, most of the time a change in memory will result in a change of socket.
I dont think AMD can call both the new 940pin and 1207pin the AM2 socket (as they are obviously different) - so when you mentioned that I thought u had gone off the rails.... but looking about now, I cant see the rails - so i must have gone off them as well :P

Also, I'm not 100% sure what the differences are, but DDR3 ram on graphics cards are GDDR3 ram.... Are they any different to what a normal computer would use? I have not a clue.... but maybe? :P
 
GDDR3 != DDR3 (they aren't the same). A point to note is that the pin out for DDR2 is the same as the pin out for DDR3 so there would be no problems with memory sockets. All it would take is for AMD to extend their memory controller to handle DDR3 in a revision and we'd have DDR3 support. I think this is what The Inquirer is getting at.

However as far as I'm aware, AM2 (940 pin) is using DDR2 and Socket F (not sure if it's still called that but 1207 pin socket) will be using DDR2 Buffered (and ECC) memory.
