Ddr2-800?

Yea i read some of the article at Anandtech..
pretty kool that DDR2 will be on pc's soon.. or later..
and i saw the Windows XP 64 preview..sad performance when
it comes to games....

 

You're talking about an Os that was designed for 32bit, is a preview and is one of the first desktop edns deisgned for 64bit. Tall order dont you think?

 

It is more to do with immature graphics drivers than anything else.

 

ok yea i forget drivers. Iirc Via have only released beta 64bit drivers for their mobos, intel more than likely have some out.. dunno bout the rest. As with all first gen stuff - optimisation comes later.

?? i thought DDR2 had more pins? Looks the same to me or are they just using a photochopped image on a normal dimm?

 

DDR2 can't be *that* close
at least has to wait until intel get their FSB1200 chips out there
sure you could use it as overclocking memory on current intel platforms but most motherboards hit a ceiling well before DDR800
that is the first thing i thought when i saw the corsair pic as well, photochopped, the "label" looks more like a graphic, too clear compared to the rest of the photo

corsair really doesnt have any specifications on their site at all, a bunch of pages with just waffle but no numbers or anything

 

You will be waiting a while then, even a transition to 1066 isn't planned till next year DDR-2 will be supported by the upcoming Intel chipsets Alderwood and Grantsdale and will run the memory synchronously for DDR2-400 and DDR2-800 and asynchronously for DDR2-533 and DDR2-667. Of course DDR2 will initially be launched with 200-266MHz clock speeds (DDR2-400 and DDR2-533), rising to 333MHz and 400MHz. Via, SIS and nVidia are all likely to release chipsets with support this year.

If anyone is confused about numbers here is a brief guide.

DDR2-400
Clock: 200MHz
Module known as PC2-3200 (3.2GB/s)

DDR2-533
Clock: 266MHz
Module known as PC2-4300 (4.3GB/s)

DDR2-667
Clock: 333MHz
Module known as PC2-5400 (5.4GB/s)

DDR2-800
Clock: 400MHz
Module known as PC2-6400 (6.4GB/s)

 

what sorts of latencies would DDR2 modules run at?
if the DDR500 range would be the lower end of the scale then would they be the ones that would run at relatively tight timings compared to the cas2.5/3 of now

 

Useful Intel page of validation results and shows latencies

Its confusing to me..
but its alot better than the type of ram i got now..
