You have heard about Intel G45, Intel G43. Both are integrated video supporting the Intel LGA775 processors. Although it differs by a digit, there is something different between the two integrated chipsets.

Basically, there are some differences between the two. For example the ASRock G43-FullHD does not support FSB1600 processors. The highest processor supported is FSB1333. Secondly, the internal Graphics of G43 is X4500, and G45 is X4500HD. The major difference is with or without full hardware decode acceleration of MPEG2, VC1 and AVC. It means G43 needs more CPU power to decode. Thirdly, the GPU clock in G43 is 667MHz while in G45, it is 800MHz.

The G43Twins-FullHD supports the LGA 775 for  FSB1333/1066/800MHz CPUs Intel® Core™ 2 Extreme / Core™ 2 Quad / Core™ 2 Duo / Pentium® Dual Core / Celeron® Dual Core / Celeron®, supporting Penryn Quad Core Yorkfield and Dual Core Wolfdale processors. It has solid caps for CPU power and it is powered by Intel® G43 + ICH10 Chipsets. This board supports both Dual Channel DDR3 1066/800 (2 x DIMM slots) with max. capacity up to 4GB and Dual Channel DDR2 1066/800/667 (2 x DIMM slots) with max. capacity up to 8GB.

For the integrated graphics, it is equipped with Intel® Graphics Media Accelerator X4500, Pixel Shader 4.0, DirectX 10, Max. shared memory 352MB. It also has a 1 x PCI Express 2.0 x16 slot (green @ x16 mode) for external graphics card.  There are three VGA Output options: D-Sub, DVI-D and DisplayPort with ASRock DVI_DisplayPort Card and it supports HDCP function with ASRock DVI_DisplayPort Card for Full HD 1080p Blu-ray (BD) / HD-DVD playback with ASRock DVI_DisplayPort Card

In terms of expansion, it has 6 x SATAII 3.0 Gb/s connectors, support NCQ, AHCI and Hot Plug functions, a  PCIE Gigabit LAN 10/100/1000 Mb/s. It also has a  7.1 CH Windows® Vista™ Premium Level HD Audio (ALC888 Audio Codec),  1 x WiFi/E header.

In terms of overclocking, it supports ASRock OC Tuner, I. O. T. (Intelligent Overclocking Technology). Other features include Smart BIOS, Energy Saving Design.
