Asus P5E3 Premium X48 DDR3 Motherboard Page: 1
Introduction & Specification
Asus P5E3 Premium
Back in December '07 Overclock3D took a look at Asus' P5E3 Deluxe motherboard. Based around Intel's X38 chipset and with  DDR3 support, the board managed to impress us with it's great performance and excellent bundle. Therefore, when Asus contacted us a few weeks back and asked if we'd be interested in reviewing the P5E3 Premium, the first question to blurt out of our mouths was "Haven't we already done that?"
However, after a lot of explaining, Asus finally convinced us that there was a lot more to  the P5E3 Premium than a few minor changes to the motherboard and some extra accessories thrown in the box. For a start it was furnished with Intel's very latest X48 chipset and had some other nifty modifications to help increase its overclocking performance.
Obviously the X48 chipset is what a lot of enthusiasts have been waiting for. After all it was probably only a couple of weeks after the X38 was released that the X48 was announced, leaving a lot of people wondering if they should wait out a bit longer to get an extra ten X's on their future motherboard.
So, what does the X48 actually offer? Well the general consensus is that the X48 is just an X38 chipset speed-binned for use with the latest Intel CPU's that use a 1600mhz FSB. While this certainly holds a lot of truth, the X48 does bring a couple of new tricks to the table - mainly in the memory department. So let's quit the small talk and take a look at the specs of the board:

Asus are well known for packing their motherboards full of features, and with a specs list longer than a roll of Andrex the P5E3 Premium certainly isn't any different.
FSB 1600Starting with CPU and Memory support, the P5E3 supports all current LGA775 Intel chips along with the most recent 1600FSB 45nm parts. However, while the X48 chipset only natively supports DDR3-1600 memory, Asus have ramped up the unofficial support on the board to DDR3-2000 (memory permitting of course).
EPUNext up on the list is Asus' "little bit for the environment" - the Energy Processing Unit (or EPU for short). The EPU is an onboard, hardware-based power saving IC controller that digitally monitors and fine tunes your CPU's power supply in real-time, providing improved VRM efficiency under light and heavy loads. According to Asus, this can provide up to 58.6% CPU power savings - but only when Intel's on-chip energy saving "C1E" technology is disabled.
WiFiJust like on the previously reviewed P5E3 Deluxe, the P5E3 Premium also supports the latest 802.11n WiFi technology while also keeping backward compatibility for the older (and more widely used) 802.11g standard. Asus have also included two WiFi antenna's in the box -but we'll get on to that over the next few pages.
Now that we've got some of the lesser interesting features out of the way, let's move on and take a look the contents of the box, and more importantly - the board itself...

Packaging & Contents
Asus Premium and Republic of Gamer motherboards probably have some of the best packages in the motherboard industry. From LCD displays to remote controls and LED lit I/O shields, Asus have included it all in with some of their previous motherboards. With this in mind, let's take a look at what the P5E3 has in store for us today...
Asus P5E3 Premium Box Asus P5E3 Premium Box
Asus P5E3 Premium Box Asus P5E3 Premium Box Flap
Starting with the outer-box, the P5E3 Premium follows roughly the same design as all of Asus' previous P5* series motherboards. The front of the box is fairly plain featuring only a semi-transparent "AI" logo on a black background, while around the back Asus have printed a specifications table (much like the one on page #1) along with a collection of four images depicting some of the most prominent features of the board.
Much like the Asus Republic Of Gamers boards, the P5K3 also features a flap at the front of the box which can be lifted to reveal even more details about the features of the board.
Asus P5E3 Premium Contents Asus P5E3 Premium Package Contents
Packaging inside the box is fairly standard, with each of the accessories being individually sealed inside their own plastic bags. The motherboard is separated from the accessories by a cardboard insert, and placed inside its own anti-static bag.
Here's a run-down of exactly what's included:
UltraDMA 133/100/66 cable
FDD cable
6 x Serial ATA cables
1 x 2-port Serial ATA power cable
ASUS Q-Shield
User's manual
ASUS WiFi-AP @n manual
3 in 1 Q-connector
1 x 2-port USB2.0 / 1-port IEEE1394 module
2 x Optional Fan for Water-Cooling or Passive-Cooling only
ASUS WiFi-AP @n omni-directional antenna
Support Disks
Asus P5K3 Premium I/O Plate Asus P5E3 Premium I/O
Have you ever build an entire PC only to find that when you go to insert a network cable or USB device that a stupid little bit of metal from the I/O blanking plate is wedged in there? I most certainly have, and judging by Asus latest Q-shield idea, they have too. As we can see from the images above, Asus have done away with the metal tabs in favour of a padded conductive surface. Top idea!
Asus P5E3 Premium 3-in-1 Asus P5E3 Premium Optional Fans
Moving on to the optional fans...these coolers have been included with many of Asus' Premium, Deluxe and ROG motherboards for quite some time. Designed to clip on to the finned heatsink that covers the mosfets at the top of the board, the fans pull air up through the heatsink fins and expel the hot air out the back of your PC case. They are reasonably quiet and come complete with 3-Pin connectors so that they can easily be controlled using the BIOS or Asus software.

Finally we have the 3-in-1 connectors. These three small blocks are quite simply a godsend for the enthusiast who regularly disconnects their motherboard and is then faced with the frustration of trying to place the power/reset/activity LED connectors back on the motherboard header. They are also very clearly labelled - so no need to refer to the manual while setting your new motherboard up ;)

Board Layout & Features
On the surface, the P5E3 Premium looks to have exactly the same layout as its elder brother the P5E3 Deluxe (and indeed a lot of the P5* series). However, a little birdie at Asus tells me that there's more to this board than meets the eye, so let's take a closer look.
 Asus P5E3 Premium Motherboard Asus P5E3 Premium Motherboard
Both the P5E3 Premium and Deluxe follow exactly the same black, orange, red, blue and white colour scheme, with the only recognisable difference between the boards being a change in colour for the Northbridge and Southbridge heatsink covers.
As per usual for Asus, the 8-Pin EPS-12v connector is located on the top-left of the board, keeping any cables trailing across the board to a minimum. Over on the right side of the board, the ATX connector sits just below the floppy disk connector and allows for easy routing of the PSU's ATX cable around the top of the motherboard without interfering with the CPU socket area.
The board features two PCI slots, three PCI-E x16 slots and one PCI-E x1 slot. In most scenario's you will have access to at least two PCI slots (or one PCI slot and one PCI-E x1 slot) for expansion cards. However when running any kind of Crossfire setup this will be reduced to only one PCI slot.
Asus P5E3 Premium I/O Ports Asus P5E3 Premium SATA/PATA
In terms of connectivity, the P5E3 Premium is fully loaded. The rear I/O panel features 8-channel audio, six USB 2.0 ports, two eSATA ports, two WiFi antenna jacks and an IEE1394 port. At the bottom of the board you will also find six SATA ports, one legacy PATA port, one IEE1394 header and two USB 2.0 headers.
Asus P5E3 Premium Socket Area Asus P5E3 Premium Mosfets & Chokes
No expense has been spared on the 8-Phase VRM power circuitry; with Asus opting for low RDS (on) MOSFETs, Ferrite chokes and Japanese made conductive polymer capacitors. All of this should ensure extremely stable and clean voltage being provided to the CPU while also maintaining around 95% efficiency.
Clearance around the socket area is also very good despite the close proximity of three aluminium heatsinks. During our testing we were able to use several large CPU coolers including the Sycthe Infinity and various models from OCZ.
Asus P5E3 Premium 3-Phase DDR3 Asus P5E3 Premium Overvolt Jumpers
While most motherboards (including Asus' high-end ROG series) implement 2-phase power system for the memory modules, the image above-left shows that Asus have gone above and beyond the call of duty by installing a 3-phase solution on the P5E3 Premium. This should provide the DDR3 slots with rock solid, droop-free voltages essential for successful memory overclocks.
Over to the right of the DDR3 modules are two jumpers labelled OV_NB and OV_CPU. Disabled by default, these two jumpers open up a whole range of dangerous Northbridge and CPU voltages in the BIOS which would otherwise be hidden. While most users on air/water cooling will more than likely kill their hardware by using these options, the extreme cooling enthusiasts amongst us will probably be grinning from ear to ear.
Asus P5E3 Premium Power Asus P5E3 Premium Realtek
Just when you thought the power delivery orgy was over, Asus have also implemented a 2-phase system for the X48 Northbridge. While a lot of overclocking issues are often blamed on vdroop of the Memory and CPU, the stability of voltage supplied to the Northbridge often goes hand in hand with the boards ability to reach high FSB's.
Also seen in the images above is the Realtek RLT8110SC chip responsible for the on-board gigabit ethernet.
Asus P5E3 Premium Express Gate Asus P5E3 premium Southbridge
Asus P5E3 Premium Jmicron Asus P5E3 Premium Firewire
Sandwiched in between a PCI and PCI-E slot is Asus' latest invention, the "Express Gate". Essentially a USB stick hard wired to the motherboard, the Express Gate features bootable operating system that can be invoked during system startup. Some screen shots of the OS can be found on the next page.
As the X48 chipset doesn't provide native support for IDE, Asus have installed a JMicron JMB363 controller. The JMB363 connects to the PCI Express bus and provides support for a single PATA device and two SATA II devices. Similarly, support for IEE1394 (Firewire) is provided via Agere's FW3227 controller.

On most of Asus' previous motherboards, the more "advanced" BIOS options have been left for their top end Republic Of Gamers motherboards. However, with the P5E3 Premium featuring some impressive hardware upgrades that even the ROG boards can't match, let's take a look at what the BIOS has to offer.
Asus P5E3 Premium BIOS Asus P5E3 Premium
Skipping past the boring Hard Disk/IRQ sections of the BIOS and straight into the good stuff, we can see that all of the overclocking options on the P5E3 Deluxe are held under a single header called "AI Tweaker". The top few lines of this section cover areas such as CPU Ratio, FSB Strap, FSB frequency, PCIE Frequency and DRAM Frequency all of which can be adjusted either by directly keying in the values or using the +/- keys to toggle through each option. Preparations have been made for the new Intel Penryn chips with the CPU Ratio setting supporting 0.5 multipliers. Additionally, the FSB Frequency can be set at anything up to 800mhz - but you can carry on dreaming if you think you'll get anywhere near that!

Moving down the page (and its a bloody long one) takes us to the Memory options. While a lot of Asus' previous non-ROG motherboards only provided users with a handful of the most basic memory timings, the P5E3 Premium takes things to the other end of the spectrum by literally bombarding you with a whole host of intriguing settings that will more than likely have even the most hardened enthusiasts reaching for the how-to guides.
However, to be fair on Asus, a large number of the options are briefly explained over on the right-side of the screen with some basic pointers as to whether the option is likely to improve system performance or stability when overclocking.
Asus P5E3 Premium Voltages Asus P5E3 Premium Voltages
Voltage options is yet another area where some of Asus' non-ROG boards suffered - but not any more! Once again Asus have tipped the scales in totally the opposite direction by not only providing a massive (and potentially dangerous) range of voltage options, but also by allowing the user to manually type in the voltage they require. However, don't be fooled - while the BIOS does allow you to type in exactly what voltage you require, it will always round it up/down to the nearest selectable option. Some of the voltage ranges can be seen below:
CPU Voltage: 0.85000v - 2.1000v (0.00625v steps)
CPU PLL Voltage: 1.50v - 2.78v (0.02v steps)
FSB Termination Voltage: 1.20v - 1.50v (0.02v steps)
DRAM Voltage: 1.50v - 2.78v (0.02v steps)
NB Voltage: 1.25v - 2.21v (0.02v steps)
SB Voltage: 1.05v - 1.20v (0.15v steps)
Clock Overcharging Voltage: 0.70v - 1.00v (0.10v steps)

Asus P5E3 Premium Profiles Asus P5E3 Premium Profiles
While most motherboard manufacturers will have you reaching for the bootable floppy disks in order to update your BIOS, Asus have included their extremely easy to use EZ Flash 2 utility on the P5E3 Premium. Simply copy the BIOS binary file to a floppy disk, USB stick or FAT32 hard disk and perform the upgrade from within the BIOS. It really couldn't be easier.
Similarly, the Asus O.C Profile utility allows users to save their current BIOS settings to an external storage device. Considering the sheer volume of options available in the P5E3 BIOS, this will undoubtedly prove to be a massive time saver for restoring your previous BIOS settings after a CMOS battery failure or other fault
Asus P5E3 Premium Express Gate Asus P5E3 Premium Skype
As we've already mentioned, the Asus Express Gate is essentially a bootable USB memory stick soldered to the motherboard. During the startup of the P5E3 Express, you are given a default of 5 seconds to choose if you'd like to boot into the Express Gate environment for quick access to applications such as Skype or a Firefox-like web browser.
While some people will probably find this handy, I cant help but feel that this feature could have been put to much better use with the inclusion of some stability testing tools (Prime95, OCCT, Memtest...etc) to avoid the need to boot into Windows every time you want to test a new overclock setting.

With the P5E3 Premium having probably the most advanced power delivery system of any board we've tested to date and a BIOS with more options than you can shake a very large stick at, the board certainly looks like a good candidate for being a top overclocker. So without further ado, let's see what its capable of...
Maximum Overclock
The Asus Maximus and DFI Lanparty boards have always been favourites of mine for for their ability to take a CPU to its overclocking limits. However, the P5E3 Premium totally blows them out of the water, managing to squeeze an extra 100mhz out of our Q6600 CPU with 1.5vcore. Similarly the board also beats out its elder X38 based "Deluxe" brother by 60mhz.
Maximum FSB Speed
With many of the lower-end Intel processors showing great overclock potential but often being crippled by low multipliers, having a motherboard that can obtain high-FSB speeds is a must. By reducing the multiplier of our Q6600 test CPU down to x6, the maximum FSB speed we was able to obtain from the Premium was 491mhz.
While 491mhz may not seem a great achievement where FSB speeds are concerned, the average Q6600 chip tops out at around 500fsb regardless. With this in mind we also tested a QX9650 ES chip we happened to have in the office at the time and managed a slightly more respectable 527mhz FSB.

Result Observations
Both the Maximus Extreme and P5E3 Premium DDR3 based boards led the pack in the majority of results. This is most likely down to the extra bandwidth that DDR3 provides, but with only minute differences between each of the results. It's extremely hard to pick any one board out as a definite winner.

3DMark is a popular synthetic gaming benchmark used by many gamers and overclockers to gauge the performance of their PC's. All 3DMark runs were performed a total of 5 times with the highest and lowest results being removed and an average calculated from the remaining 3 results.
Result Observations
The extra bandwidth of DDR3 memory used on the Maximus Extreme and P5E3 Premium boards doesn't seem to carry much weight when it comes to Cinebench and 3DMark, with many of the DDR2 boards producing identical or better results. Similarly, there is no noticeable difference between the X38 and X48 chipsets.

Quake 4 is a game built on the Doom 3 engine. Benchmarking was performed using Quake4Bench and a custom timedemo recording along with 0xAA, 0xAF settings at a resolution of 1024x768. The benchmark was set to run a total of 5 times, with Quake4Bench automatically calculating an average result at the end of the run.
F.E.A.R. is a game based on the Lithtech Jupiter EX engine. It has volumetric lighting, soft shadows, parallax mapping and particle effects. Included in the game is a benchmark facility that taxes the entire PC system. This benchmark was run a total of 5 times, with the highest and lowest results being excluded and an average being calculated on the remaining 3 results.
Bioshock is a recent FPS shooter by 2K games. Based on the UT3 engine it has a large amount of advanced DirectX techniques including excellent water rendering and superb lighting and smoke techniques. All results were recorded using F.R.A.P.S with a total of 5 identical runs through the same area of the game. The highest and lowest results were then removed, with an average being calculated from the remaining 3 results.
Result Observations
The P5E3 Premium manages to keep up with the rest of boards in the test, indeed showing that it is in no way crippled when compared to any of Asus' Replublic of Gamers boards or indeed any of the Nvidia chipset based boards (Striker II / XFX 780i).

Asus P5E3 Premium X48 DDR3 Motherboard Page: 11
Up until today there has always been a clear line between the two types of Asus motherboards. The P5* Deluxe/Premium series has always been for those who want a good board at a reasonable price with some mediocre overclocking options and on-board extra's such as WiFi. While the Republic of Gamers series has always been aimed squarely at overclockers. 
However, with the release of the P5E3 Premium Asus have closed the gap. Not only does the P5E3 Premium feature a BIOS that allows you to fine tune the most intricate of MCH, NB and CPU settings, but the range of voltage options and the ability to simply key in your desired setting gives the P5E3 Premium possibly the best BIOS that Asus have released to date. This has certainly paid off too, with the P5E3 Premium being able to take our stubborn Intel Q6600 chip all the way up to 3.75ghz and effortlessly hit 520FSB on a QX9650.
To put it simply, the Asus P5E3 Premium is a Maximus killer. Sure it doesn't have some of the fancy bells and whistles of the Asus Republic of Gamers line-up, but if Asus were to slap a couple of power buttons, a CMOS reset switch and a blue & white colour scheme on the P5E3, it could easily pass as the best ROG board they have ever released.
Unfortunately availability of the board at the moment is extremely limited. Searching Google, I was able to find only one website selling it for around £230. However, with none of our recommended retailers or other preferred retailers showing stock, I can only assume that the board is still on pre-order. For this reason, I will reserve opinion and pricing of the board until concrete figures are available.
The Good
- Extensive BIOS options with ability to manually enter voltage selection.
- Managed 490FSB on our Q6600 chip and 520FSB on a QX9650.
- 3-phase power delivery to DDR3 slots.
- Simple but innovative features such as the Q-Shield
- Good overall layout.
- Motherboard jumper to unleash insane voltage options.
The Mediocre
- Still not a fan of heatpipes and copper-look aluminium heatsinks
- Motherboard colour scheme a tad ugly.
- Express Gate could have been put to much better use.
The Bad
- Nowt!
