Intel X48 Motherboard Round-up: ASUS, ECS, & Intel

ECS X48T-A Features


As was the case with the Asus board, with ECS a dark brown or black PCB remains the color of choice.  Black is probably what they were shooting for as the X48T-A is part of their limited Black Series.  ECS runs the rest of the palette dry with their color scheme: two red PCI-E x16 slots, two black PCI 2.3 slots, a single yellow PCI Express x1 slot, and then grey and yellow marked DIMM slots for dual DDR3 with support up to 1600MHz.  The 'Black Series' logo almost seems to be an afterthought, a sticker hastily added to the motherboard on a clean section near the DIMM slots.


The X48T-A comes in a nicely designed box, featuring an ice dragon of sorts with some nifty graphics around the model name and two different logos marking the X48T-A as a deluxe limited edition and part of the Black Series of motherboards from ECS . The bundle was a bit less flamboyant, with a handful of SATA and eSATA cables, an IDE cable, and a labeled I/O shield being the sole goodies.  Media consisted of a quick installation guide and user's manual with a support CD-ROM.  The Crossfire section in the manual is seriously outdated, with pictures of exterior dongles and the like describing the installation procedure.

Front panel and three bright orange USB headers are found near the front, with a handy schematic placed nearby for quick reference.  Touches like these are always welcome, because no one wants to go searching for their manual anytime a cable comes loose.  SATA Ports 1-4 wind up just under the tip of a larger video card, but ECS has anticipated this by throwing in a set of SATA cables that are bent 90 degrees. The IDE port is inexplicably placed on the far edge of the board, furthest from the drives it would connect to.  I guess ECS assumed that most users won't be using it, so placement wasn't an issue, but anyone still using IDE devices will have to run cables up and over their other components.  Front panel audio or CD-In cables, will also need to run to the far corner as well.

ECS' cooling system goes under the name QoolTech II, and consists of two copper heatsinks placed over the North- and Southbridges, connected to a third radiator by means of heatpipes.  Oddly, said radiator doesn't interface in any way with the outside of the case, and will require adequate airflow around the CPU socket to keep temperatures in check.  Closer inspection of the heatpipes reveals that they are simply glued to the heatsinks rather than properly machined in place; this method probably isn't as efficient at transferring heat.


The X48T-A also lacks in another area - it only offers a single 3-pin fan header in addition to the 4-pin CPU fan.  Placement of that one fan header was also less than optimal, snuggled in between the 8-pin ATX power (which itself is in the crook of a heatpipe) and the CPU heatsink/fan.

Another gripe we had concerned the retention clip for the graphics adapter.  The clip itself doesn't present a large problem, although we've become accustomed to not seeing them anymore; it's the placement of three capacitors immediately next to the clip that bothers us.  Trying to reach in and push down the clip with fat fingers is one thing, worrying about knocking a cap off the board is another.

Rear I/O features PS/2 mouse and keyboard ports, COM, eSATA and S/PDIF-In and Out, 6 USB 2.0 ports, 2 LAN (one each from Intel and Realtek chips), and 5 audio jacks with TOSLINK thrown in as well.  Overall it's a really good-looking board from ECS that's sure to catch the eye, but it still has a few issues that we would like to see ECS iron out.
