i thought intel dropped ddr2 like ages ago? or are the motherboard manufacturers using some custom chip or chipset mod to enable ddr?
Not sure what rock you have been living under, but DDR2 is required for any Intel chipset from the 925X and up according to the document "Full-size PDF of Performance/Mainstream Desktop Chipsets Chart
And as for Nvidia, any chipset from the NForce4 Ultra and up according to this document "NVIDIA nForce for Intel - Desktop
Now I am not sure about AMD, but I am sure that someone here can answer that...
oh sh1t! i got told...
naaaah, twas a typo. shuda read ddr(1)
