Doh...maybe even more of a delay.

I think Lezmaka was being somewhat sarcastic to make a point. :)

Correct. But the main problem, AFAIK, is that the Jedec standard isn't 100% final yet ( or am I not up to date here? )
So, the official DDR2 could be slightly different from the GFFX DDR2. That's why nVidia calls it GDDR2, AFAIK.
But I could be wrong on this...

it seems reasonable that JEDEC has yet to have the specs finalized on ddrII. have they even finalized DDR400?

Someone correct me if I'm wrong....


But I thought JDEC has really nothing to do with DDR Ram chips....they are all about Ram modules. You know, those sticks that have several ram chips on them that you shove into motherboards.

So, to the extent that the Ram Module specification can impact the spec of the ram chips on them, I suppose it could make a difference.

That being said, Graphics card companies don't really give a crap one way or another about JDEC specification.

DDR-400 modules have only 200 Mhz DDR Ram chips on them. Graphics cards have been using much faster chips than that for ages....none meet any kind of JDEC "standard." All that graphics card companies care about is that the Ram Chip specs are similar enough between manufacturers so that they are not limited to supply from one memory company.

This is why we have the GDDR-II/III "specs". It's just an attempt to ensure that all these memory makers produce chips with similar specs, so that they can pick and choose the memory chips they want to use based on price.

i was talking about desktop memory for DDR400 and DDRII
