THE 790GX chipset is AMD’s latest offering and supports the newest Phenom X4 9950 CPUs that require a 140W TDP (Thermal Design Power). Some previous 780G chipset motherboards were unable to run the new processors due to the power requirements of the 9850 (125W) and 9950 (140W) CPUs, so it’s a good thing that AMD supports their own latest CPUs with their latest chipset as it was rather silly to have NVIDIA integrated graphics the only choice for those CPUs.
With the launch of the Athlon 64 CPU, AMD moved the memory controller from the chipset to the CPU. This means that the memory support is dependent on the CPU and not the motherboard. If you install a AM2+ CPU like the 9950 into a 790FX motherboard DDR2-1066MHz memory is supported. An older CPU like the 4800+ X2 will only support DDR2-800MHz but will work on this motherboard without issue to compatibility.
The new SB750 Southbridge brings RAID 5 support to the AMD chipset arena, Advanced Clock Calibration, Super I/O, the fix for the SB700 internal clock generator malfunction, and support for the new features that were featured in the SB700 including support for 14 USB ports compared with 10 on the SB600 chipset and support for up to 6 SATA devices compared to four on the SB600 Southbridge.
DrMOS is MSI’s server class component chip. This chip replaces the Discrete MOSFET chips that are present on most motherboards with something called a Driver MOSFET. DrMOS has the advantages of lower working temperatures, high power efficiency, lower power loss and high-frequency CPU support on a smaller chip than standard MOSFETs.
GreenPower is MSI’s trademark for power efficiency with DrMOS. Compared to Discrete MOS, DrMOS can save up to 7W in CPU PWM meaning less energy consumed and better environmental impact than traditional MOSFETs. XpressCool maintains a low temperature under the most stressful situations. RapidBoost delivers higher quality power with lower spike noise and faster response, meaning DrMOS increases the potential over-voltage and overclocking of the system.
The HD3300 is based upon ATI’s HD2600 series chips that were released as the low-end of last year’s ATI graphics card lineup. The differences between this chipset and the previous HD3200 on the 780G include a 700MHz graphics clock compared to the 500MHz on the HD 3200. MSI includes a 1Gigabit chip (128MB) of 1333MHz DDR3 memory that acts as a Framebuffer called SidePort memory. The Unified Video Decoder found on the HD series of cards is also present on the HD 3300 integrated graphics meaning that HD playback of Blu-Ray and HD-DVD content is fully supported in hardware.
