Abit AB9 Pro: Board Layout and Features
Abit designed a board that has one of the more interesting layouts we have seen in a long time. While the board was very easy to install in our mid-size ATX case we did have some issues with utilizing our Optical drive in the top bay due to the location of the JMicron powered IDE port that is located in between the number two PCI Express x1 slot and the number one PCI slot. There are six fan headers on the board that can be controlled by the µGuru Windows utility. The Abit board features an excellent five-phase voltage regulator power design with high quality capacitors located in each major component section of the board that yielded superb stability.
The DIMM module slots' color coordination is correct for dual channel setup based upon the premise of installing DIMMs in the same colored slots for dual-channel operation. The memory modules are easy to install with a full size video card placed in the first PCI Express x16 slot. The 24-pin ATX power connector is located along the edge of the board along with a series of capacitors for the memory modules. Abit places the four-pin 12v auxiliary power connector at the top of the first memory module but completely out of the way of aftermarket cooling solutions we utilized.
The six Intel ICH8R SATA ports are color coded red and are conveniently located to the left of the ICH8R Southbridge and battery. The SATA ports feature the newer clamp and latch design. We found the positioning of the SATA ports to be excellent when utilizing either the PCI-E x1 or PCI 2.3 slots. The ICH8R is passively cooled and remained cool to the touch throughout testing.
The first three of five auxiliary fan connectors are located at the bottom edge of the board. The clear CMOS jumper is color coded yellow and is located in between the battery and ICH8R chipset. The CP80P post port debug LED, chassis panel, µGuru chipset, and red 1394a connectors are located along the left edge of the board. The blue USB 2.0 connectors are located above the SATA ports.
The board comes with (1) physical PCI Express x16 connector, (2) PCI Express x1 connectors, and (2) PCI 2.3 connectors. The layout of this design offers a very good balance of expansion slots for a mainstream board while providing excellent clearance space for graphics card utilization. However, the layout in this area is very unusual if not a bit chaotic. Our main issue is the location of the floppy drive connector at the bottom of the board along with the JMicron JMB363 IDE and SATA ports being sandwiched in between the PCI-E and PCI slots in the middle of the board.
The four-pin Molex power connector that will be required for future GPU products is located above the PCI-E x16 slot along with the Silicon Image 3132 SATA port. Abit informed us some of the unusual port locations were predicated upon ensuring proper power delivery, stability, and trace layouts based upon the capacitor locations. However, we still have to wonder if some of these layout choices were design gaffe that accidentally made it into production.
Returning to the CPU socket area, we find an ample amount of room for alternative cooling solutions. We utilized the stock heatsink/fan in our normal testing but also verified a couple of larger Socket-775 cooling solutions such as the Tuniq Tower 120 would fit in this area during our overclocking tests.
The Intel P965 MCH chipset is passively cooled with a low rise heatsink unit that did not interfere with any installed peripherals. This heatsink is part of the Abit Silent OTES technology that includes a heatpipe system and additional passive cooling for the VRM components. This system kept the MCH cool enough that additional chipset voltage was not a factor in our overclocking tests.
The rear panel contains the standard PS/2 mouse and keyboard ports, LAN ports, and 4 USB ports. The LAN (RJ-45) ports have two LED indicators representing Activity and Speed of the connection through the Realtek RTL8168 Gigabit PCI-E chipset. The audio panel consists of 6 ports that can be configured for 2, 4, 6, and 8-channel audio connections for the Realtek ALC 882D HD codec. The panel also consists of two S/PDIF (optical in/optical out) ports, and an external SATA 3Gb/s port via the Silicon Image 3132 chipset. All in all, Abit included an excellent combination of ports although another two USB ports would have been handy for additional peripherals.

The DS4 will be reviewed. Gigabyte has stated they will not bring it into the US but we are still trying to convince them (really more like begging and calling our marketing rep at home on the weekends to beg some more) to release it in the States. The copper backplate can be removed off the DQ6 and I really did not see any benefit with it on in testing. It makes for a good rebate with the price of copper today. ;-)The AHCI issues stay the way they are at this time. It is frustrating to say the least. I was being a bit sarcastic in my statement but it is a little harder than it should be to enable AHCI on the ICH8R.

I'm in Taiwan, so the DS4 is all over the place :)Capt Caveman - Saturday, October 21, 2006 - link
Not sure if you live in the US or not but Gigabyte is not bringing/selling the DS4 to the US.Also, the copper backplate for the DQ-6, can be removed with a tworx(sp?) screwdriver. At XS, many just went to Home Depot and got longer screws for their HSF.

Excellent review that'll help potential buyers enormously. A couple things:1. Error in the chart (page 14): There is a discrepency between the chart (3-4-3) and the commentary (3-4-4) :)
2. In memory review Wesley always put tRP ahead of tRCD, while Gary does the opposite. It'd be nice to have a consistency for less experienced users!
3. Gary, did you test the P5W-DH with wirless module installed or without? I recently found out the wirless module could skew CPU/memory-sensitive benchmarks on this board big time. I'm not sure if my finding is true in general, but if it is, then the comparison between a board with such feature and a board without it can be unfair.
4. Can Sandra Unbuffered be really an indication of general performace? @400FSB, setting memory ratio 4:5 (DDR2-1000/4-4-3) boosted the score by a whooping 400~500 MB/s from the ratio 1:1 (DDR2-800/3-3-3), which never realized for other tests in a meaningful way. Oh this is about my own testing. :D
Thanks for the great review.

Thanks for the comments.1. The timing error is corrected. Jarred and I were editing at the same and we found out after the article went live that our saves to the final copy would overwrite each other. Bad timing for several other mistakes that have been cleared up now.
2. Wes is wrong. Just kidding, we will get on the same page. :)
3. I turned off the WiFi on the PSW-DH. The scores were even worse with it on. Not that they are bad but the board runs a little looser timings in order to overclock at the high end. DFI also does this with their boards targeted for the overclocking market.
4. Sandra Unbuffered can be an indication of performance in apps that are memory sensitive. This is not always the case but it is one of the better yardsticks available at this time.

Do you plan on comparing the Gigabyte DS3 vs the S3 version for us to know if there are performance/overclocking issues with the S3?The only difference so far between the DS3 and S3 is "All Solid Capacitors".
Are there any other difference I'm missing?
The S3 is $110, and the DS3 is $150.
I have a hard time to justify paying an extra $40 for only "all solid capacitors"
The term is nothing but marketing to me so far.
I haven't seen any proof of a performance/overclocking issue between the two boards.
If you or anyone else plan on testing the differences or can provide something(Ex: any review link) stating otherwise, that would be great.

In theory, cleaner power.... but aside from the theory, the onboard sound does start flaking out the higher you go. This has been true on 2/2 boards I've tried it on. So an add-in card is needed for the higher overclocks... 460+ish.goinginstyle - Monday, October 23, 2006 - link
No issue here with the Biostar board at 500FSB and the Realtek ALC-883. It sounds fine but a X-FI is still the way to go for gaming.Gary Key - Saturday, October 21, 2006 - link
Yes, the S3 will be in part two. :)
Lothar - Saturday, October 21, 2006 - link
The only other differences I found were RAID support and 2 extra USB ports...It's not worth the $40 price difference if performance and overclocking results are the same IMO.
