ECS X48T-A @ Guru3D
“Typically an X48 chipset based mainboard will start at roughly 250 USD. The two chips the mainboard manufacturer has to purchase from Intel total up towards 90 USD alone. Pretty high-end gear for sure as Intel’s X48 chipset brings support for the all new 1600 MHz FSB processors, two 16x PCI-E 2.0 slots, which you can use for ATI CrossFire, two ATI graphics cards and heaps of nice features.”
ASUS P5QL-E @ OC Club
“When it came to overclocking the Intel Core 2 Q9450 on the ASUS P5QL-E I ran into a few problems getting it stable anywhere above 2940MHz (420×7). Leaving all of the voltage settings on auto, I was able to get the FSB frequency all the way up to 400MHz with a multiplier of 7x. However, I did end up jumping to 1.355V on the CPU voltage to get it stable at 420MHz x 7 Multi giving me the speed of 2940MHz.”
