Actually, the chipset AMD RD790 class high-end was on hold sense ATI company purchase , and only the delay in the release of new generation AMD processors put aside the announcement of RD790 for later period. Formally this chipset can work, also, with socket AM2 processors .
Today appeared an alarming information about the possibility of announcement transfer OF RD790 for later period. Problem, as report source close to motherboard producers , consists in AMD desire to simultaneously announce phenom generation processors and RD790 chipsets . The Company note that the support Of hyperTransport 3.0 from chipset RD790 should be realized correctly, and it must be completely checked with engineering models phenom. Currently AMD cannot provide motherboard producers with such processors (support hyperTransport 3.0) models . For this reason AMD accepted the solution to put off the announcement of RD790 to the middle of November.
Some motherboard producers will use this delay to equip their products on the base of RD790 with the new south bridge SB700, which will appear in the fourth quarter. We should note that motherboard on base of chipset RD790 can support four memory modules DDR-2. In the case of processor with socket AM2+ they will work in the regime DDR 2-1066, but if socket AM2 processor is used , then it is necessary to install DDR 2-800 memory .
