Today we can preview another X79 motherboard that we have in our labs – the dashing Intel DX79SI (Siler) Extreme Series Motherboard which is part of the Sandy Bridge-E reviewer's kit, and one of the better inexpensive choices when it hits the retail shelves.
The DX79SI (Siler) continues Intel's line of skull themed enthusiast motherboards since the D975XBX (Badaxe). We particularly liked the color scheme and plastic carton box that the motherboard came in.
Only passive cooling heatpipes on this board, which is acceptable as the IOH only has a TDP of <10W. We wonder – If Intel themselves can provide 8 slots (Quad Channel) for memory expansion on their own boards, why do most of the other 3rd party motherboard vendors then just make do with 4 (or god forbid, 6)?
The I/O Panel. Besides the glaring lack of PS/2 connectors (Intel boards have been that way since X38 I think) for the OCD overclockers, we see a CMOS reset switch on the left, a stingy 2 USB 3.0 connectors (provided by a Super Speed capable NEC D720200AF1), 2 Intel Gigabit RJ45 Ports (82579L and 82574L), 6 USB 2.0 ports from the X79 chipset and a vanilla Realtek ALC892 for 8 channel audio.
