Asus P5E3 Premium WiFi-AP @n (Update)

X48 Motherboard Comparison, Part 2

We already reviewed the P5E3 Premium WiFi-AP @n edition motherboard in our original X48 Motherboard Comparison, or at least we thought we had. Asus later revealed a completely new circuit board, trickily given the same “revision number.” Because the review samples were not the same as the retail units, we secured the later version for a retest.

What is most noticeably different about the P5E3 Premium WiFi-AP @n Edition retail samples is a missing PCI-Express x1 slot in the top position. Some of the capacitors have also been moved around, and we have no idea what changes might be beneath the surface.

We’re only focusing the P5E3 Premium WiFi-AP coverage on changes, but we did find one in BIOS: Asus has added separate GTL Reference voltage adjustments for each CPU core.

Readers not yet familiar with the P5E3 Premium WiFi-AP can look back to our previous review for details on the things that haven’t changed in the retail circuit board revision.
