ASUS did a marvelous job with the layout, it is nearly perfect. The only complaint is the location of the CPU-power-connector, which is too close to the socket and thus will create problems installing huge CPU-coolers. ASUS also removed the heatpipe alongside the memory banks, which will help make replacing the CPU-cooler easier. The significant difference compared to the Deluxe series are the two connectors on the Northbridge-cooler for watercooling-systems.

The heatpipe keeps the temperatures at bay; at least in normal conditions you won't have troubles keeping the board stable.


The VRM is an analog 8-phase design, compared to the Deluxe series ASUS enhanced the design, which yields lower power-consumption.


The memory slots are placed in such way you can replace memory, even with large PCIe graphic-cards installed; a good change compared to the Deluxe series.


Between the PCIe x16 slots you see the IDT PCIe switch chip. This neat chip splits one PCIe x16 port to two PCIe x8 ports. The downside is the slavery slot is only PCIe 1.0a compliant, so if you plan to buy PCIe 2.0 graphic cards, you are out of luck: they will not be detected, or even worse they may be fried when you insert such a card.
A welcomed addition are the power-on switch and cmos-clear switch below the bottom PCI slot. The cmos-clear switch isn't needed, because the BIOS can re-boot after failed overclocked attempts.

Network connectivity is provided by two Marvell chips, but why the second is only a PCI chip is beyond our imagination, as it will ruin the perfomance if you use gigabit. A VIA VT6308P provides two ports of FireWire 400. This board contains no onboard audio, because ASUS decided to add an external audio card called "Supreme FX II," which should increase sound quality over onboard solution. As usual, an Analog Devices AD1988B is used.

Another plus are the angled SATA and PATA connectors.


ASUS stuck with the AMI BIOS, this time with the 2MB version, which gives additional languages besides English. A nice gimmick, but we would rather see extended help information in the BIOS first before adding any languages with misleading translations.

The most annoying feature of the ASUS BIOS is that while overclocked the CPU will not receive idle-voltages. The CPU multiplicator is reduced but the VCore remains.


We have to state that we always recalculate the bench results to nominal frequencies. Most vendors do an overclock to their products, maybe to get more bench-points, but we nullify such attempts. The Blitz is overclocked with 2666.6666MHz, 3333.3333MHz, underclocked with 366MHz FSB or overclocked with 367MHz FSB:

There are no differences in the OC capabilities compared to the Deluxe version, FSB reaches 485MHz. We think our E6700 is stuck at this FSB frequency. In a few days we will test the E6750, then we will see more valid results.

Please note that different bios revisions may give different results, all benches are done with AUTO settings without altering any BIOS option besides CPU VCore, NB VCore and FSB Termination Voltage.

Gordian Knot/XVID 1.1.3:
For our Gordian Knot testing we took a PAL episode from "Babylon 5" with a length of 41 minutes, 57 seconds and 8 frames.

We tried to "emulate" the most common usage of Gordian Knot:
1st: We have a perfect master, so we only de-interlace the content and resize it without any other manipulations; we marked this as "fast."
2nd: You get bad mastering on many DVDs, especially "old" stuff or when the studios are in a hurry for the release. In this case you want to improve the picture quality, which is done by filtering the content. You can choose from lots of filters for any purposes you can think of, but we only used the most common "undot," "FluxSmooth" and "MSharpen." Of course, we also de-interlaced, filters were done before any resizing took place (which is slower). We marked this as "slow."

If you need more information about filters, we recommend reading the doom9.org forum.


The same episode we encoded, we used for our MP3-testing. We don't recommend using MP3 for encoding, because AC3 can do the job better, but nearly 42 minutes gives us approximately the length of any given album.
A measurement in seconds, as many sites do, is useless, because the differences are too small. So we used the built-in play/CPU ratio; this means the CPU is encoding x-times faster then the track-length. Fast memory does not play an important role here. For your convenience we also show you the single-threaded benches. They will be produced with any other L.A.M.E. version, because only LameMT can do more than one thread and take advantage of a second dice.
We used this setting: lamemt --vbr-new -q 2 -V 2 -m j --strictly-enforce-ISO --resample 48



As mentioned in the BIOS section the board suffers from not being able to reduce CPU VCore in idle-mode when the CPU is overclocked, but the VRM is improved compared to the Deluxe series. When only slightly overclocked it is close to the MSI P35 Platinum. Only when extreme overclocking is applied it seems the VRM is not very efficient, but this is still a huge step forward for ASUS.

We did run our tests with 2nd LAN and JMB363 disabled and without the LCD-Display.



ASUS has made a huge step forward compared to the Deluxe series. The VRM is improved, the layout is far better and we encountered no problems running any memory modules. The drawback is the BIOS overrides your EIST settings when you overclock, almost any other board can reduce the VCore, anyway, and a reduction of 0.2V will always help to to reduce your power bill.

The PCIe switch chip is a nice add-on, but fails to be future-proof due its lack of PCIe 1.1 compatiblity for the second PCIe x16 slot.

We can abstain from the LCD display, watercooling-option and thermal sensors to lower the price tag. Right now, this board is available for about €240,- which is far too expensive. We wish any Deluxe version came as an "R.O.G." board with superior design and without all the fancy stuff, since WiFi is not needed for real gamers. The competition is significantly lower priced for a similar value.

This is indeed a fine board, but due the high price tag it fails to receive our recommandation. Due to the high prices of DDR3 memory we would also suggest to stay with DDR2 boards. ASUS offers the Blitz Formula, the twin brother of the Blitz Extreme, but at about €30,- less.
