DDR3 out

you know DDR3 is just out well my question is AMD wont take it up until they sort out there timings but my question is INTEL have got DDR3 mobos out now but INTEL who supply APPLE now when will they change to DDR3
 
maybe somebody else can understand what you are asking, but with that grammar and lack of punctuation, i have no idea what your question is. are you asking when Apple is going to start including DDR3 in their systems?
 
DDR3 memory starts at 800mhz and goes upto 1325mhz and is still 240pin memory. Some boards out now are 1066mhz and may be compatible if DDR3 is simply faster memory of the same type. So far no boards by either AMD or Intel specifying DDR3 have been seen. Those may be out late this year or early 2008.

They make DDR3 1600. There are boards the specify that they work with DDR3 such as this.
 
Besides, who really wants DDR3? ooo! faster speeds! but the latencies get slower with every speed increase, it is a direct function. I don't see the point.
 
$559 for 2gb? no thank you! I thought $369 for a pair of Hyper X PC6400 2gb dimms was high! :eek: :P The board at the link there shows DDR2 800 as the standard and supports the faster memory. That shows that DDR3 is simpy a faster DDR2 memory with a 3 seen on it. Many with 1066/800 boards will still go for 2gb of 800mhz memory there. They like the 4-4-4-15 over 5-5-5-whatever.

The point is you get more bandwidth. The relative latencies go up yes, but if you have DDR2-800 @ CAS4, that CAS4 is the same amount of waiting as CAS2 on DDR-400 (10ns). Yes you lose more cycles but you have a lot more that you can give up.
 
DDR3 has been out for quite some time now, but I still have no idea what you're actually asking Robina...

It seems as Intel always has the get go over AMD. It usually is a few months lag time that AMD switches to the next memory standard, though right now, it is pointless for anyone but the extreme enthusiast to switch, due to really high prices. Of course, you'll get 3 more FPS in some games, in addition to the wow power.
 
Well Intel is trying to push the next step in technology, they always do. I think they try to push everything a little too early, but then again if everyone waited until something was affordable before trying to push it we'd probably still be using AGP, PCI 2.3 and PATA :P

AMD pushes stuff too but Intel has always been about the whole platform, until recently AMD was only about CPUs
 
After reading it again i'm still not clear as to what you're asking, but AMD can't simply move to DDR3 like Intel because it's current line of processors have an onboard memory controller, unlike Intel who relies on the chipset. So if Intel wants to support DDR3, they can just create a new chipset (P35, G33), whereas AMD would have to release a new processor. Which is why AMD waited so long to have DDR2 support on their CPU/motherboards.
 
They don't have to make a whole new processor though, they just have to design a new memory controller and integrate it which is basically all Intel has to do as well. Granted, there is the added need to fab new CPUs and change socket for DDR -> DDR2 but the main reason AMD waited because the added bandwidth doesn't do much for K8 and DDR2 was still expensive compared to DDR.

I shouldn't have said they needed to create a whole new processor, all they need to do is re-design the memory controller. This is a perfect example of the Athlon 64 based 939 and AM2 CPU's.
 
I was waiting here to see what AMD would come out with for a quad core lineup and saw only two FX-74s on the Socket F type board. To see the most out of an old Socket A board with DDR400 you needed the XP3200+ there for the most part. The current Core 2s see 533-1066mhz as the standard depending on model. 800 and 1066mhz memory work more with the top models for either AMD or Intel.

The 6000+ X2 was selected here to run that with PC6400 memory for that reason. With the present boards out DDR3 would simply backclock to the 1066 or 800mhz standard seen on the board it goes on. New boards with the faster buses will be able to take advantage then for the increase in bandwidth.

Now that I read it again, you didn't really say it but I guess it was kind of implied. But getting back to the OP, I don't know when Apple will use DDR3, probably not for a while yet though.
 
Apple like anyone else will be waiting to see the new boards come out that have the faster memory standard in order to use them. The term implies a faster range from 800mhz up over DDR2's 533-1066mhz. The most common for DDR2 is still 800mhz while some support 1066. New chipsets have to be worked out for the new memory.
 
I think he wants to know when will Apple pick up DDR3...

:confused:

Again that will be the wait to see Apple using newer boards when those come out. Usually there will be some tupe of news blog or press release when that comes about. You just have to sit back and wait for the most part.

Pretty sure AMD is staying with DDR2 untill AM3, think all the AM2+ Barcelona off shoots have a DDR2 memory controller. But heard the AM3 will have DDR2 and DDR3 memory controller so you can run them on a AM2+ board, but not a AM2 board, go figure. But I would say a AM2 board would be pretty much outdated by then anyway.
 
And everyone always says Intel goes through too many sockets :D

I think you are right though, they wont have DDR3 support on AM2. All I was saying is I'm pretty sure there's no physical need for a socket change for DDR3 support.
