ASUS seems to be getting better at every aspect of motherboard manufacturing, from better design, to better features, they've got a better BIOS as well. We're not talking about the amount or even granularity of its overclocking features and options (which is plenty really), but option description text that will actually make sense to the user rather than the usual cryptic one-liners. Granted, it is still far from perfect, but we've noticed continuous improvements over the past year.

No surprise, the P5E3 Deluxe turned out to be a very competent overclocking motherboard, easily hitting the high 470-480MHz FSB range without the need to increase any chipset voltage. We were able to achieve a maximum stable FSB of 500MHz with a 0.16V increase to the MCH, but the board became unstable beyond that.

Test Setup

Now let's see what the ASUS P5E3 Deluxe is capable of performance-wise. We compare the new X38 based P5E3 Deluxe to its its predecessor, the P35 based ASUS P5K3 Deluxe as well as some of the competing Intel X38 motherboards around such as Foxconn's X38A and Gigabyte's GA-X48T-DQ6. To benchmark these boards, the following hardware configuration will be used:-

  • Intel Core 2 Extreme QX6850 processor (3.00GHz)
  • 2 x 1GB Kingston HyperX DDR3-1333 @ 7-7-20 CAS 7.0
  • Seagate Barracuda 7200.10 200GB SATA hard disk drive (one single NTFS partition)
  • MSI GeForce 8600 GTS 256MB - with ForceWare 162.18 drivers
  • Intel INF and AHCI driver set
  • Microsoft Windows XP Professional with Service Pack 2 (and DirectX 9.0c)


The following benchmarks will be run to determine the performance of the ASUS P5E3 Deluxe:-

  • BAPco SYSmark 2004
  • Futuremark PCMark05
  • SPECviewperf 9.0
  • AquaMark3
