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.

I am surprised I did not see this posted on a news site somewhere announcing Intel has a X6600. ;-) The line was corrected this morning to (X6800, E6700, E6600) although late last night my mind was probably thinking unlocked E6600 equals X6600 for some reason. Thanks for the notice! :)

In recent months the memory market has moved from a 1GB kit to a 2BG kit being the common memory configuration.2GB*
Excellent article, I'm assuming the OCing results were default voltages on the chipsets and/or the cpu?

To be honest, I would say it's quite different!
The storage controllers have been changed a lot... there is now a port-multiplier type of SiI chip that connects to one of the ICH7 ports, which provides driverless (!) RAID. Also, the previous board had a Marvell SATA/PATA controller instead of the JMicron controller.
For another difference: the new board is missing the PCIe 4x slot, too.
Anyway, thanks for the great overview! And it's amazing how fast after launch you got this up.

Thanks for your comment. We added information to the P5W-DH page with a little more info on the differences from the earlier board.nicolasb - Wednesday, July 19, 2006 - link
...is what is the actual impact on system performance of different memory speeds and timings? Possibly you guys actually derive a direct erotic thrill simply from knowing that your memory timings are 4-3-3-9 ;-) but what the rest of us care about is whether any given timings actually provide a tangible improvement to running applications. If I spend an extra £200 on memory, am I going to get an extra 10fs in a certain game, or just an extra 1fps if I'm lucky? That's what I want to know.Conroe is a new chip and it is by no means obvious (to me, anyway) whether the speed/latency of the memory will have a greater or lesser impact on the performance of the system than is the case for Netburst or A64 chips.
So, how about re-running some of your benchmarks on one particular board and producing results for different memory speeds and latencies?
Wesley Fink - Wednesday, July 19, 2006 - link
The original plan was to publish a Conroe memory article prior to this huge motherboard and memory roundup. The move forward of the Conroe launch by two weeks shifted our schedule quite a bit, as we discussed in the Buying Guide. we have found the timings DDR2 memory can achieve give a rough idea of the performance hierarchy on Conroe. That is 1067 at 4-4-4 is a bit faster than 800 at 3-3-3 is faster than 667 3-2-3. 667 is generally faster than nything slower regardless of timings.With 13 DDR2 kits it was impossible to do proper and complete performance testing on all the memory on Conroe and still deliver an article when you want to read it. There will definitely be followup reviews of memory on Conroe anwsering your questions in detail. We knew there would be complaints from some, but we also hoped you could understnad the roundup is posting 4 days after an early Conroe launch - and you can't even buy Core 2 Duo until 7/27 or later.
We wanted to provide solid info as soon as possible for those planning a Conroe purchase. We thought our finding that almost any Elpida value DDR2 will do DDR2-800 4-3-3 at about 2.2v was big news you would want to know, we will fill in the rest of the performance data as soon as we can.
As it is the roundup is over 15,000 words and one of the largest articles ever published at AT - in word length - and we really tried to be brief in each review. We really like giving our readers exactly what they want, but sometimes the realities of time and volume shift our priorities.

Although I can understand what you're saying, maybe the following should not have been included in the introductory page.I guess the only surprise was that the comparison wasn't there. :P
Honestly, I tried to jump right to that section only to find rather useless comparisons of ridiculously expensive memory (which I won't buy) and "value" (read cheap) memory (which I won't buy). Also, can you really tell me that it was much of a surprise that the expensive memory all topped out at roughly the same speed (~1100, 5-5/4-5-15)? Nor am I particularly surprised the value memory could overclock reasonably well, but how about tests of the memory that I think most of your readers are likely to buy? I've been looking at DDR2, and you can get memory rated at DDR2-800 for a little more than the DDR2-667/533 variety, and still a lot less than the DDR2-1000 modules.
I know that you were pressed for time, especially with the launch being pushed forward. I just think (and it is only an opinion) that other tests should have been given priority over the ones you've completed.

Also, what motherboard was used for the DDR tests? Often, value RAM is paired with a "value" motherboard. Value RAM may not look so well when paired with a value motherboard. I'm wondering how cheap we can go for reasonable peformance :)Gary Key - Wednesday, July 19, 2006 - link
We stated at the end of page 18 that we will be publishing performance results of the value memory roundup shortly. The amount of time required to test these seven modules at four different settings in several different applications was incredible and warrants a separate article update.
