so DDR3 ram went to 204 pin configuration

so that makes our 1333mhz fsb 9262's incompatible with DDR3 ram

 

>.> haven't resellers been saying it wasn't ddr3 compatible for a few months now?

 

i don't know, haven't kept up with that.

my point is to have ram that is closer in speed as our fsb, like the available cpu options are.

 

I still see a lot of desktops built with ddr2 800 ram. Can't be that big of a improvement, but what has me curios is how are new notebooks that are supposed to support ddr3, but only have ddr2 and sellers say that it will only support ddr2?

 

The Core 2's problem is not memory bandwidth . . . DDR3 does not do a whole lot for it. See this article for a comparison of different memory speeds/timings on the Core 2 Duo:

It makes little difference.

Your Clevo D900/D901 is a beast one way or another.

 

I would imagine it would take some time for DDR3 to get off the ground in laptops. Currently DDR3 is still an extreme part, and has been commercially available for over a year. New laptop chipsets would have support for DDR3, which rules out dropping it in any existing DDR2 laptop. I think the main advantage of mobile DDR3 isn't speed, but the slightly reduce power consumption and heat output.

 

DDR3 will get off the ground (its ground is still slightly above DDR2's) once lower latency chips are released. It'll be nice to have a compatible chipset once that happens.

 

i heard you can up 2 twice the performance as the ddr2

 

You get twice the theoretical bandwidth, but real life results aren't even close. Optimally, DDR3 performs 15% faster than DDR2, and in worst conditions, performs the same.

 

Ram speed hasn't been the bottleneck on computers for a very very long time, the only time it really seems to make much of a difference now is adding ram to a system using say 512mb. An example would be people using windows vista with 512mb and upgrading to 2 gigs. Thats when you can see a improvement.

 

DDR3 is just more bandwidth, worse latency. Performance near neutral in the real world at the moment. At current latency, it is perceptibly slower than decent DDR2 RAM on the market today. It is just there to make nicer profits for the poor memory makers relying on people going: "ah! 3 must be better than 2, right?". Same story with DDR to DDR2 - it was not worth it until DDR 2 started getting the latencies and prices right. As to matching the FSB to the CPU to the RAM - the key point is to get an optimal ratio. Divide FSB by 4 and memory by 2 (if dual channel).

 

what about the ddr3 that has been in gpu's for so long? can you make the same argument regarding teh gpu market's use of ram?

 

Different type.

GPU is GDDR3. Not DDR3.

 

No, GDDR3 runs cooler which allows them to be clocked faster. Memory is more of a bottleneck for GPU's than CPU's.
