The Board - P43R1600Twins-WiFi
Moving right along, it's time to look at the board itself. The layout of the connectors on the board is almost identical to the P45R2000, which is disappointing as the placement of the 24-pin power connector is located in the same spot. Another cable nightmare here guys.
This board is also a combo board; it supports DDR2 and DDR3. However, where the P45R2000 had more DDR3 slots, the P43R1600Twins has more DDR2 slots. It has a total of four DDR2 and two DDR3 slots. The board still supports the same FSB and DDR2/DDR3 speeds, so there are no advantages of bus speed support by either board.
The same voltage regulation components are used. Solid state is good by us and any board swapping to solid state gets the TweakTown thumbs up. Four phases keeps the CPU fed and the space around the CPU is ideal for large coolers.
The rear I/O panel changes from the P45R2000 series. Firstly, there is only a single eSATA port which uses the same bridge design that the P45R2000 uses; quite annoying to say the least. The other major difference is this board loses an RJ45 Ethernet connector. This board only comes with one, though I find one Gigabit port enough for my needs at this point in time, as I'm sure most of you will, too.
Moving to the expansion slots and this is where we get another change between the P45 and P43 board. The P43 chipset does not carry the same Crossfire support that the P45 does. While you can still do Crossfire with it, you have to have it configured in the older 16/4 configuration with no splitting of the channels. To this end, ASRock has not included a second x16 PCI-E slot on this board; rather, they go for a single GPU option. This gives the board an extra PCI-E x1 slot to make up three in total and three older PCI slots.
