I don't know why you say this... DDR3 Sticks are expected to start @ DDR3 800 (1600 mhz) so even the very first kits, will beat everything that is out now on DDR2 by far...Quote:

Btw, those chips in the modules of the pictures in the first post are rated for 533MHz @ CL8.
yeah and BH-5 was rated to 166-200mhz @ 2.5-3-3 :fact:Quote:

AMD's IMC is compatible with DDR3 and DDR2, however all Intel chipsets that support DDR2 will not support DDR3. Intel in attempt to prevent confusion for their customers, forced Jedec to accept a different pinout, even though the pins are the same and the difference for voltage is small enough for Bios based correctionQuote:

DDR3 MC's may be backward compatible, but the current ddr2 mc's certainly aren't ddr3 compatible - so there won't be any am2 ddr3 boards (which would be possible if what you said was true).Quote:

Alas this was not the case, probably at the behest of the memory manufacturers not intel - as I'm sure they'd like to sell some new ram for these new cpu's and motherboards people will be upgrading to in order to recoup their development costs.
1. Will AM2+ mobos be able to use DDR3?
2. What price can we expect for the first shipment of DDR3 modules to cost?
Any insight here guys?
AM2+ is going to support DDR2 and HTT3.0Quote:

You never wait to upgrade... Never.... If you want to upgrade, do it..

amd has no use for DDR3 ATM, ddr2 already is overkill for K8 architecture, sure things will change with K10, but DDR2 doubled bandwidth for K8 cpus, but there is nearly no performance increase when going from 939 to am2 so there has to be enough unused bandwidth to feed 4 cores... (hope so :) )Quote:

DDR2-800 is double than DDR-400.
But only when we're talking about theoretical b/w.
Considering the throughput on Rev.H parts has been seriously bumped I wouldn't be surprised if AMDs QCs would really like any available bandwidth.
In addition, the new IMC configuration on QCs might accelerate the hunger even further; 32bits/clk/core is a stretch.
I'm not buying anymore DDR2 untill I see credible test results of this DDR3 tech.
are we talking mobo's here?cause the pics in the TS are memory?Or aren't there any pics from DDR3 mobo's yet?
im not impressed yet. yeah the frequencies are friggen awesome, but CAS 7? come on guy. thats like putting a diesel into ferrari. sure its fast, but it takes forever to get going :stick:
bt_medic04,
Think about what happens to the length of a clock cycle when frequency climbs.
It gets shorter...
lets just think about it in terms of latency.Quote:

it would take the exact same amount of time.
