AMD 790FX Chipset

Both northbridge, southbridge and mosfets are cooled passively with a copper heatsink, making the product completely silent. Overall heat is really not bad, you can actually touch the copper blocks with you fingers. Also, the 8-pin power connector, placed perfectly fine.

On the topic of power distribution. A good number of 780G boards had an issue with high-TDP Phenoms. Phenom X4 9850 and 9950 carry respective TDPs of 125 and 140Wtoo much power for some mid-range motherboards to handle. AMD made sure that the 790GX mainboards supports the high-wattage processors and overclocking of these.

The board supports four 240-pin unbuffered non-ECC DDR II SDRAM DIMM sockets and up to 8GB of memory can be installed on the board. For AM2 processors, DDR2-533/667/800 is supported. For Phenom AM2+, memory supported is DDR2-667/800/1066. It also support Asynchronous clocking mode between FSB and DIMM.
