Intel Broadwater Chipset Memory Controller Changes
 

Intel’s latest July 2006 specification update on the Broadwater family of chipsets reveals some changes to the memory controller. All Broadwater family chipsets including G965, P965, Q965 and Q963 will no longer support 1Gbit DDR2-800 DIMMs. This limits the maximum system memory for DDR2-800 equipped systems to 4GB.
