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.

Very well-written article guys!Thanks for taking the time to enlighten us all.
Just wanted to point out that the Mushkin Redline sticks can be had right now for $355 AR. At that price, I may just have to grab 'em myself!

It was pretty much shown that the effect of using memory dividers for Athlon64's was rather minimal while most dividers were more adverse for Netburst.How large of an effect does using memory dividers have on the Conroe?
Wesley Fink - Wednesday, July 19, 2006 - link
The effect of memory dividers is much smaller on Conroe than we saw on Netburst. In fact memory dividers on Conroe behave more like AM2 - probably the result of the "apparent" reduction in latency with the intelligent look-ahead in memory. Core 2 Duo is not Hyper-Transport, so 1:1 (533) tis still theoretically the highest performing setting, but we were hard pressed to find any measurable advantage of 1:1 in most situations.We had tested a number of high-performance dimms on Conroe before we wrote the Buyers Guide, but there just wasn't the time - or room - to include full memory performance data in the Guide. We do have memory reviews in process that will provide specifics to your questions.
We can summarize what we have learned about memory on Conroe so far. DDR2-667 is quite a bit higher in real perfomance than DDR2-400 or DDR2-533 (1:1). We would consider DDR2 to be the minimum memory that should be used with Conroe. Going up from DDR2-667 we found the following - from fastest to DDR2-667. DDR2-1067 4-4-4 is a bit faster than DDR2-800 3-3-3 is a bit faster than DDR2-667 3-2-3. Timings are very important above DDR2-667 and you can give up any performance advantage with slower timings. DDR2-667 is a good match to COnroe bandwidth, and is better perfoming than 533 or 400 by a wider marging than you find above DDR2-667. It also appears Conroe responds better (performs better with increases) to DDR2 bandwidth increases than either Netburst or AM2.
Wesley Fink - Wednesday, July 19, 2006 - link
We would consider DDR2-667 the minimum memory to use with Conroe, and faster timings do generally improve performance.Sunrise089 - Wednesday, July 19, 2006 - link
I would like to know this as well.txt2000 - Wednesday, July 19, 2006 - link
Just wondering, if your going to spend ~$400 on memory if you would be better off with 4GB value DDR or 2GB high performance.Patsoe - Wednesday, July 19, 2006 - link
I suppose that completely depends on your usage pattern. Almost all of my activities fit within 512MB, and probably anything I do fits within 768MB. So getting faster RAM would do more for me than more of it.If you could fill 3GB, then a setup with 2GB will see a lot hard-disk swapping... even a very slow 4GB of RAM will do better in that case.
Andy4504 - Wednesday, July 19, 2006 - link
Anything over 1GB results in the OS addressing your memory differently. Never did the reasearch on how that different addressing affected system performance however.supremelaw - Wednesday, July 19, 2006 - link

And, your earlier article on the nVidia 590 chipset
for Intel also dovetails perfectly: nice photos too.
August+ should be VERY interesting.
Many thanks!

"The board was very stable with our X6800 and X6600 Core 2 Duo processors ..."It should have been E6700 (or maybe E6700)
