Gigabyte GA-965P-DQ6
Basic Features
The Gigabyte GA-965P-DQ6 was one of the most talked about and hyped boards at Computex 2006. We were excited when our test sample arrived. After getting through all of the marketing spin on the box and included documentation we found a board that provided everything but the kitchen sink (we believe that to be on the bottom of the board). While the list of options is definitely impressive along with the general look of the board, it is performance that counts in this market sector. Did it deliver? The answer is yes and no, as we will discuss shortly.
The board features 12-phase power, an all solid capacitor design, an impressive silent heat pipe system, Dolby Digital Live and DTS support, eight SATA 3Gbps ports, and a very good layout considering the sheer amount of options on this board. Our one gripe is the Crazy Cool plate on the back side of the board underneath the CPU socket. While we noticed this option worked as well if not better than the ASUS Stack Cool 2 system, the plate is just thick enough to rule out the usage of several aftermarket cooling systems that require the use of a back plate. Granted, some quick and minor modifications to the attachment screw lengths worked in several cases, but for a high end board Gigabyte should expect the user to upgrade the retail CPU cooling system.
Basic Performance
Gigabyte did indeed deliver excellent performance with this board. In fact, the overall performance of the board placed it squarely in the top of our roundup. The board exhibited excellent performance and stability throughout our testing regimen while providing a certain amount of gee whiz discussion amongst the staff members when first noticing the board. What is even more amazing is that this performance occurred with a board that was not running on all cylinders at the time. We had several issues that were solved with a constant stream of BIOS updates, but there was one that neither us nor Gigabyte could overcome.
The board would at various times simply refuse to accept a voltage change in the BIOS with a guaranteed lock up when changing the DRAM voltage. After changing various voltages either together or in a singular manner, the board would enter a reboot cycle that could only be stopped by turning off the power and clearing the CMOS. We were finally able to change the CPU voltage that allowed us to overclock the board to our reported results. However, we were not successful in truly finding the limits of this otherwise impressive board. The initial street pricing of $269.99 also has us concerned. After testing with other CPUs and memory, we ruled out BIOS issues and believe our board to be faulty. We have a new retail board on its way that will hopefully fix the issue.
Overclocking
Even with the aforementioned BIOS issues, we were able to clock this board to an impressive 376FSB. Gigabyte has sent us test results with a new B2 stepping 6 X6800 showing a fully stable system running at 6X498 with the current D27 BIOS. The board ran extremely cool during our overclocking tests indicating a well engineered heat pipe system, although the area around the CPU would need to be actively cooled if a liquid cooling system is utilized. During testing for the maximum FSB clock we ran into the BIOS issues and were not able to extend past the reported 376FSB due to our inability to set the MCH and FSB termination voltages. The only other noticeable drawback in overclocking this board is the lock on increasing the CPU multiplier when utilizing the X6800. We look forward to providing a full review of this board in the near future.

With the release of new Quad SLI beta drivers I would like to know what board is compatible with both the Conroe & Quad SLI. Being CPU bound in graphics I think it would very interesting to see. The ASUS P5N32-SLI SE is not on the Quad-SLI list. The Asus P5N32-SLI Deluxe is not either.Bo
Gary Key - Thursday, July 20, 2006 - link
It should be on the list shortly. This is the board that NVIDIA has been using to test and display Quad SLI on with Conroe. We also understand this board will probably make its way into several Quad SLI systems according to NVIDIA. It will be interesting to see how this board performs against the nF590 in a couple of weeks. ;-)

If Core 2 Duo is sucking up so much less energy, why have I not heard anything about the need to NOT buy the 500-650 watt power supplies. It would seem to me that a processor and mainboard that consumers so little power would not need anything more than a good 350 or 400 watt power supply, even in an SLI configuration.It would be nice to see something written up in your review that stated...
Hey, these processors are going to require X amount of power on the lower end and X amount on the higher end. Given power supplies are typically only 75-80% efficient and leaving another 10-15% left over in overhead, you should be using power supplies with a watt rating of X.

Jon,Anand went over the power requirements in the CPU review article. However, from a platform level the current 7900GTX and X1900XT cards in SLI or Crossfire will require a very good 500+ watt (on the edge with CrossFire) power supply with Conroe, AM2, or Netburst CPUs. In fact, we highly recommend and use 700+ watt machines in our systems to ensure proper power delivery when running SLI or CrossFire while overclocking. The power requirements of the next generation GPUs for SLI or CrossFire will require 700w power supplies and we generally will see 900+ watt supplies for those who expect to overclock both the CPU and GPU. While we have seen the CPUs reduce their power requirements over the last two years (except at the high end until Conroe, AM2 EE is great), the GPU requirements along with the platform chipsets (ATI RD580 is the exception currently) have sky rocketed. By the time you add a couple of large hard drives, optical drives, SLI or Crossfire, and a FX60 or 955XE, you are already limited by the typical 400~500 watt power supply. While Conroe will make a difference compared to most Netburst based CPUs and the upper end AM2 processor series, it is not enough to even think about dropping below 500w at this time. In my personal systems, the first item I budget for is a really good power supply, never skimp on proper rail voltages and quality, it is the basis for a trouble free system.
Hope this helps....

Would you guys mind doing some tests to back that up in Part 2? Reading SilentPCReview.com, there's some pretty convincing arguments that the need for higher wattage is overblown. And 900W+ is hard to believe...pretty soon you'll be talking about dedicated wall sockets.I think most folks are talking about one video card, not SLI. I'd like to issue a challenge: try a test with the Core 2 Duo, a Geforce 7600GT like in the "Building a Better Budget PC" article, and a 300W Seasonic PSU (or any 80% efficient, true-to-ratings). Then, see how it effects overclocking. That PSU can run an AMD64 x2 3800+ and a 7900GT, why couldn't it run the Core 2 Duo with voltage to spare?
There, I've thrown in my gauntlet.

#1) Paul - My point in bringing up the Digital Thermal Sensor capability of the Core 2 Duo chip and it's "possible" support on the P965 was mainly just to show that there may in fact be certain features the P965 has that are superior to the 975X. Certainly not planning any extreme overclocking and a good HSF is certainly a priority, but still utilizing the Core 2 Duo chip to its fullest abilities is important to me and that means a motherboard that supports this Core 2 Duo feature. If P965 boards support this feature out of the box and the 975X boards don’t, it’s a factor that could play into my purchasing decision.#2) Thanks Gary & Wesley for the explanation on why you didn't include the AB9 Pro motherboard. That makes perfect sense. It seems to me this is the board to target but to be at this point in the game and NOT have a mature enough BIOS to manipulate RAM settings is a little concerning to me. This coupled with Abit's financial issue's in the past almost have me fearful of taking a chance on this board.
I hope in your roundup article you will provide some insight into all this business with 12-phase power and solid state capacitors. What does this mean to the over clocker or the serious workstation user?
Lastly.......
Slightly off-topic here but PERHAPS something you two could include in your more extensive roundup of the next Core 2 Duo motherboards or maybe in a separate article.
On-Board Audio……….
This may be old hat to many here, but this is an issue that I haven't seen addressed anywhere recently. On-Board audio solutions have "evidently" been creaping up on SB products for sometime now. A better explanation as to the feature benefits of some of these on-board solutions (RealTek 882D, 882, 883, 885, 888, ADI, etc) and how they are implemented would be helpful.
#1) Top of this list is the confusion regarding digital audio & HD Audio. Seems every mobo now includes either Optical or Coax digital out on their back plates. What does tihs mean to the gamer, the audio professional, audiophile, or just the everyday computer user who wants to hook up an external amp and some higher end speakers and listen to very high quality stereo music. What the heck is HD Audio and what does that mean? How does it apply to the various groups I mentioned above?
#2 – If I’m going to use the digital out on my board, what difference does it make what onboard or offboard sound solution I use. If the computer is spitting out bit-by-bit digital audio data, isn’t a RealTek ALC650 digital out everybit as good as a Creative Labs SoundBlaster X-Fi Platinum Edition?
#3 – What is the deal with all the new audio codec’s out and their supposed support for Dolby Digital. What does this mean to the consumer? I would imagine 90% of all computer users here and a similar vast majority elsewhere don’t use anything more than a simple 2.1 configuration or perhaps headphones. 7.1 or 7.2 sound is worthless. Does Dolby Digital provide any extra benefits to these 2.1 or headphone listeners? Does it play back my music from .MP3’s or iTunes sound any better?
#4 – What really is EAX and is there that big of a difference between EAX 3.0 – EAX 5.0? And again, how does this relate to digital audio. If some external source is doing the audio conversion, do these technologies even matter?
These may appear to be rather easy questions to answer, but the reality is that we’ve been bombarded so badly with marketing by Creative and others with audio that most of us really don’t know what the heck it is we’re buying.
Personally, the quality of audio output is really important to me. I mostly listen to music and occasionally will play a few games. One BIG question for me is do I save $125 and go with on-board “digital” audio or not.
Thanks!
Jon

Just by looking at this article, you can see how much attention is on Intel's Core 2 Duo. I don't remember so much attention was invested for the AMD Athlon64 FXs when they were launched. LOL.Wesley Fink - Thursday, July 20, 2006 - link
We looked back at the launch review of A64 on Sept. 23, 2003. As you can see for yourself at http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">http://www.anandtech.com/cpuchipsets/showdoc.aspx?... the AMD won Business Winstone and the Intel 3.2 won the MMC Winstone. Gaming results were split, with A64 winning most and the Intel 3.2 winning Quake 3. A64 led in Workstation development and Intel in Encoding. In other words, A64 won by a small margin. The AMD lead grew over time and our coverage continued to grow.We can't remember the last time a new CPU was laucnched that was 20% to 30% faster than the competition in everything we tested. There are really no weaknesses we have found in Core 2 Duo performance. This is a once in a decade event. AMD has responded with massive price cuts that position their new CPUs much more in line with Core 2 Duo based on performance, but they really don't have an answer to conroe, since almost every Conroe chip is faster than the fastest A64. We wish AMD did have a quick fix, since competition is good for buyers.
We are fans of performance at AT, and we have been very supportive of A64 as it took the performance lead and extended it over the past 2+ years. However, those who ignore the current Cnroe advantage are not looking at performance, they are speaking from emotion. Conroe performance can not be ignored or twisted with GPU-bound benchmarks to show show something that is simply not true. Things will likely shift again in the future - AMD has shown itself to be very resilient - and we will loudly proclaim AMD's lead if they regain the performance crown.

I owe Anandtech much, you guys have consistently provided excellent quality info for years.Thx for another great article, I'm looking forward to part two.
You guys have peaked my curiosity on the tuniq tower. I didn't see it reviewed here yet. Is it that much better than the competition, it's definitely beastly looking?
