ASUS P5WD2-E: Features
Asus designed a generally well laid out board with all major connections easily reached. The board is lacking most clearance issues and was very easy to install in a mid-size ATX case. The board layout is very similar to that of the P5WD2 Premium but differs with the additional SATA RAID and single PATA ports in place of the dual PATA ports along with the new PCI slot arrangement.
The DIMM module slots' color coordination is correct for dual channel setup. The memory modules are simple to install with a full size video card placed in the first PCI Express x16 slot. The power plug placement favors standard ATX case design and the power cable management is very good. The floppy drive port connector and 4-pin 12v EZ-Pug are conveniently located on the edge of the board along with the 24 pin ATX power connector.
The Intel ICH7R IDE port connector is located on the edge of the board and did not present any connection issues in our mid-size ATX case.
The Intel SATA II ports are conveniently located below the ICH7R chipset and above the primary IDE connector. The SATA II ports feature the new clamp and latch design. Asus did not include the new cable designs in their accessory kit, which greatly enhance the security of the SATA connections. The SATA II ports are color coded for primary and secondary operation. We found the SATA 1 and 3 ports were partially blocked when utilizing the NVIDIA 7800GTX cards in both PCI-E x16 slots.
The Marvell 88SE6141 PATA port connector and Marvell 88SE6141 SATA II RAID port connectors are located to the left of the bios chip. The Intel USB connector, IEEE1394a connectors, chassis panel, and Com1 serial port are located along the left edge of the board. The CMOS reset is a traditional jumper design located above the bios chip.
The board comes with (2) physical PCI Express x16 slots, (1) PCI-E x1 slot, (1) PCI-E x4 slot, and (3) PCI 2.3 slots. The layout of this design offers a very good balance of slots and allows for numerous add-in peripheral cards.
We did not have any issues installing an ATI X850 Crossfire Edition setup in the two x16 PCI Express slots. This configuration will physically render the PCI-E x4 and the first PCI slot useless. We did not have any issues utilizing either slot with video cards containing single slot cooling systems.
Returning to the CPU socket area, we find an ample amount of room for alternative cooling solutions. We utilized the stock Intel heat sink but also verified several aftermarket cooling systems such as the Thermaltake Big Typhoon would fit in this area during our tests. However, due to the large MCH heatsink, installation of large heatsink cooling solutions could be problematic.
The Northbridge and Southbridge chipsets are passively cooled with heatsinks that do not interfere with any installed peripherals. In fact this system kept the chipsets cool enough that additional chipset voltage was not a factor in our overclocking tests. Asus places the eight-pin 12v auxiliary power connector at the top of the CPU socket area but out of the way of most aftermarket cooling solutions.
The rear panel contains the standard PS/2 mouse and keyboard ports, parallel port, LAN ports, and 4 USB ports. Located below the parallel port and to the right of the PS/2 ports are the Coaxial S/PDIF, Optical S/PDIF, and external SATA II ports. The LAN (RJ-45) ports each have two LED indicators representing Activity and Speed of the connection. The audio panel consists of 6 ports that can be configured for 2, 4, 6, and 8-channel audio connections.
The bios options are abundant on the Asus P5WD2-E, with memory voltage to 2.4v, and an extensive range of chipset, bus, and vCore voltage adjustments. Memory ratios are limited compared to the nForce4 Intel Edition boards but Asus did manage to offer enough settings to make the board competitive. The board fully supports manual memory timing adjustments or allows for an Auto setting that will set the memory to the SPD settings. You have the ability to overclock the system utilizing the AI Overclock profiles that have preset percentages or to use the AI N.O.S. feature that will dynamically overclock the system based upon system loads. The ASUS Ai Booster Utility Precision Tweaker software pictured above allows control over certain system settings within Windows.

If the board is not 100% compatible, both physically and electrically with the upcoming Conroe family of processors, I suggest that everybody take a pass. It would be just another case of Intel screwing us again with fast-track (deliberately-?)planned obsolescence ---- just as they did on the LGA775 family when the earlier boards and chipsets were (er...) "found" not to be compatible with their dual-core offerings ---which of course nicely inflates demand for Intel chipsets. And again where Yonah has exactly the same pin-count as the Pentium-M, but deliberately physically incompatible such that even the latest Pentium-M motherboards will not work with Yonah. After all, Intel needs to recoup its recent $350million investment in expanding its chip-set fabrication capability and as fast as possible. Would not like to disappoint the stockholders.Also a corollary question --- is the 975X chip-set itself fully compatible with Conroe, or is it going to have a short and unhappy life like the 915/925 chipset ??
Gotta really admire Intel in the past couple of years. While their processor engineering lost its way, their marketing gurus have become geniuses at finding all sorts of neat ways of lubricating the screw and keeping the cash rolling in.

Besides price, what is the advantage of this board over the P5WDG2-WS? Is the P5WD2-E a better overclocker than the P5WDG2-WS? Would you recommend the P5WD2-E over the P5WDG2-WS, price aside?Gary Key - Monday, January 16, 2006 - link
The P5WD2-E is targeted towards the overclocking market and for mainstream use as it should come to market about $35~$50 less than the P5WDG2-WS. The other advantage it holds is the additional PCI-E slots and one additional PCI slot if you need them, otherwise the PCI-X slots on the G2-WS will certainly hold an advantage for the workstation crowd.
I personally think the G2-WS is a better board at this point in the release cycle mainly due to a more mature bios and the 8-phase power solution. However, we have several more 975X boards to review and will hold final judgement until that testing is completed.

In the initial 955EE review, there was a claim that the high heat levels might be related to the Intel supplied motherboard. Was there any difference with this ASUS board?Gary Key - Monday, January 16, 2006 - link
We did not notice the same thermal issues the first set of the Intel D975XBX boards had with the 955EE. In fact, our replacement D975XBX solved the initial thermal issues we noticed. However, the 955EE still runs very warm, we noticed 49c at idle and up to 68c under load on the Asus board with either the Gigabyte G-Power or Thermaltake Big Typhoon coolers. The provided Intel heatsink (840EE) ran at 55c idle and up to 73c under load but we understand this might not be the heatsink shipped in the retail kit. We are trying to procure one at this time to test it.

You say there is a problem with the 882 chips? Can you run the same test on boards that used the same south bridge with a Cmedia sound chip. I know a lot of boards used the c-media at first and am whondering if this is maybe a south bridge problem or just another sign of the low quality items/drivers that realtek seems to make.Never been a realtek fan. Weather it be their low quality sound chips or their drivers.
Gary Key - Monday, January 16, 2006 - link
The 882 family of codecs is very good for an on-board solution. I believe there is still a lot of work to be done in the drivers. However, the improvements made between the R1.20 release up to the R1.29 release have been significant. We actually could watch our BF2 benchmark come to a stop during the aircraft flyovers up until the R1.27 release. There is still some stuttering and frame rates drop into the teens but overall the CPU hit rate is around 9% compared to a 67% CPU hit in drivers up to R1.26. The overall sound quality has improved in games like Serious Sam II and F.E.A.R. also. We have not tested a 975X board with the CMedia solution but have just finished testing one with the Sigmatel solution (next article).ProviaFan - Monday, January 16, 2006 - link
The review states that with two ATI cards inserted, the other PCI-E slots are not usable. Is this due to a real hardware limitation, or is it only because the ATI cards' coolers are too big? An example of a usage scenario that prompted this question: could I put a graphics card in one 16x slot running at 8x, an 8x PCI-E SCSI adapter in the other physical 16x slot, and then perhaps a 1x card in one of the remaining slots?Gary Key - Monday, January 16, 2006 - link
The slots are physically not available due to the two slot cooling solutions used on the cards. This would hold true for the 6800 Ultra or 7800GTX 512mb edition cards.
Your scenario about the slot assignments would work.

Interesting on the voltage for the CPU though having only 1.200V as the bottom limit seems a little bit limiting from my persepctive, good gaming performance though as it typically runs only 2nd to the Intel Nforce 4 SLI.I also agree that 8 Phase Power would be nice, maybe in a future revision that is made to support Intel's NGMA processors.
