Asus P5E3 Deluxe WiFi-AP @n Socket 775 Motherboard


Input/Output Panel

The I/O panel on the Asus P5E3 is fairly comprehensive as well as modern. Featuring:

* 1 x PS/2 keyboard connector
* 1 x SP/DIF Optical digital audio output
* 1 x SP/DIF Coaxial digital output
* 2 x e-SATA ports
* 1 x Firewire ports
* 6 x USB ports
* 2 x RJ45 LAN Port
* 8 channel analogue sound output
* 2 x WiFi aerials via add-in WiFI-AP @n card

io options

It's a pretty comprehensive set of I/O's and good to see a PS/2 keyboard included in there. The most unusual feature there would be dual aerials for the WiFi cards.


The P5E3's BIOS is based around the Phoenix BIOS and as usual, Asus have managed to squeeze more options in there than you can shake a stick at. I personally prefer the layout of the Award BIOS, but the BIOS with the P5E3 is hard to find fault with.

RAM timings
 The "Extreme Tweaker" part of the BIOS really hits the spot as an enthusiast. With a whole host of overclocking features, Asus have gone a long way to satiating my desire for options! Above are the CPU/FSB and memory options you have in the extensive BIOS.

OptionAvailable Range
CPU Multiplier
x6 upwards
FSB/NB Strap
FSB Frequency
200-800mhz (1mhz steps)
DRAM Frequency
PCI-E Frequency
100-150mhz (1mhz steps)

Plenty to adjust there then.

BIOS NB reference
A shortage of voltage adjustments there is not. Some of these are a little more constrained than on the Maximus RoG board but they still do the trick OK. The only one I'd perhaps like a little more on in the extreme side of tweaking in the Northbridge Voltage. Remember that DDR3 does not need as much voltage as its DDR2 counterpart. Also included is an "overclock over-charging voltage" that means you can pump even more juice into the CPU beyond the available options of the CPU Voltage Ref

OptionAvailable Range
CPU Voltage
1.1v-1.70v (0.00625v steps)
FSB Termination Voltage
1.20v-1.5v (0.02v steps)
Northbridge Voltage
1.25v-1.91v (0.02v steps)
DRAM Voltage
1.50-2.78v (0.02v steps)
Southbridge Voltage
1.050v-1.20vv (0.15v steps)
PLL Voltage
1.05-2.78v (0.02v steps)

All of the controls change from green to orange to red as you go higher and there's even a warning when you put the NB voltage at the highest to get better cooling!

BIOS OC profile

Asus have also given you the option of saving two overclock profiles into the BIOS which is pretty great and saves a lot of time.
CPU temp monitoring

The temperature monitoring in the BIOS also allows for Asus' excellent QFan control system.
BIOS voltage monitoring

And of course some voltage monitoring is included too.

All in all Asus have provided an incredibly comprehensive BIOS that doesn't fail to impress, especially considering this is a board aimed at "lifestyle" users, rather than gamers or overclockers necessarily.

looks decent enough, but why, in one of the pictures, was there a sticker over two usb ports, and a network port? :S

infact, its in the pic in the first post ^^

is it to protect it or somthing? :SQuote

Looks nice, shame the overclocking isnt as good as the rest of it Quote

Agreed, although cooling limited me tbh. Still 3.7GHz easily on a Q6600 isn't to be sniffed at. Sometimes I wish we could have a bit more time with the boards to tweak away Quote
