Gigabyte GA-965P-DS3: Overclocking
FSB Overclocking Results
We were able to reach a final setting of 7x455FSB resulting in a clock speed of 3185MHz. This board is fully capable of 500FSB rates with the correct memory installed. We still have an issue with the D9 Micron based 1GB modules not wanting to go above the 460FSB range in a stable manner. This issue will be fixed in an upcoming BIOS release and we will retest at that time. We did not have any issues reaching 510FSB with a set of D9 based 512MB modules in testing.
Our CPU voltages were set higher than normal but this is due to the VDroop on the board being around .02~.04V during testing. Also, the voltage was increased slightly to compensate for being on the edge with our memory at the 7x450FSB or higher settings. At 7x440FSB we had the CPU set at 1.4250V without issue. Although we are limited at this time in FSB rates we feel like this board offers one of the better overclocking experiences for the money.
Memory Stress Testing
Memory Tests
We take a look now at seeing how well our GEIL PC2-6400 memory operates in this board in both two and four DIMM testing. The screenshot above shows the actual memory settings used in our benchmark tests of the board. We do not modify the memory timings beyond the four major settings in our charts. The balance of the settings is implemented automatically via the BIOS. Gigabyte is fairly aggressive with their internal memory and MCH timings as our testing will reveal today.
We were able to set our timings to 3-3-3-9 by increasing the memory voltage to 2.20V with our GEIL memory. We were able to hold these timings up to DDR2-830 on this board and held timings of 3-4-3-9 up to DDR2-860. The board ran at 4-4-3-10 up to DDR2-880 before switching to the final overlclock settings of 5-5-5-15. We noticed that any memory timings above DDR2-880 required the use of auto settings to ensure a stable system. This goes back to our issue with the 1GB D9 Micron modules that will be resolved shortly.
Our settings of 3-4-4-9 at 2.20V were not quite as good as the Asus 1.02G settings of 3-4-3-10 but the Gigabyte board runs tighter overall memory latencies. We were able to keep this setting up to DDR2-840 before switching over to 4-4-3-10 settings that held stable until we reached DDR2-860. We then kept a setting of 4-4-4-12 at 2.30V up to our final overclock setting of 7x438, 3066MHz DDR2-876, with four dimms installed. This board will overclock higher with four DIMMs once the D9 Micron issue is solved.

Thanks Jarred, lopri, Aikouka for the reply.Kougar - Saturday, October 21, 2006 - link
I am rather puzzled. As best I can tell from Google, my kit of Corsair TWIN2X2048-6400 does use Micron D9s...... but I use a Gigabyte DS3 and even with the awful release F1 BIOS onwards have had no issues using them. Currently I have a stable OC of 501FSB for a 3.5ghz rating on the old F6 BIOS. Can you confirm if this kit of RAM uses D9's or not, because I am running the 800mhz RAM at 1ghz, 2 or 2.1v only, 5-5-5-15 timings, 24 hour dual Prime stable?? I have a kit of Corsair 6400c4 on the way, so I guess this will prove interesting either way.
I would also like to clarify that with the hours upon hours I spent playing around with and overclocking the DS3, I only once experienced a situation where I had to use the BIOS jumper, as I had managed to lock it into a POST/rebooting cycle. Having only used a Abit IS7 before, I can say it was a major difference I quickly noticed.
Thanks for any info, it's appreciated. And good article, by the way!

Are your 6400's the 6400 plain or 6400C4? There is a difference between the IC chips used.
We have one set of Micron D9 1GB that work properly in this board but they cost about $650 right now and had a beta SPD. We do not have every D9 1GB module available for testing but the 14 we have tried resulted in failure. Some would do 445, some would do 465. Just about every DS3 owner I know has an issue with the recent D9 1G modules not reaching 500FSB at 1:1 in a stable manner. We even tried three different boards during testing. I was able to hit 510 with the 512MB D9 and some beta 1GB Elpedia sticks from OCZ. Gigabyte agrees with our findings and it should be solved shortly.
We really like the DS3, it proved to be a very stable board in testing. As I stated at the end, this board has changed our opinion about Gigabyte again.
Thanks for the comments. :)

Gary, have you tested G.SKILL 2GB (2 x 1GB) F2-6400PHU2-2GBHZ modules on the DS3? If not please add these to your list. This is some extremely popular Micron D9 memory with favorable reviews on Newegg and our forums.Kougar - Sunday, October 22, 2006 - link
I am currently using the basic 5-5-5-12 1.9v vanilla 6400 kit, not the 6400c3 or the 6400c4. Could you please tell me which of these uses the Micron D9s, since from what you are saying I've only found incorrect info! Thanks for fully explaining this issue with the D9's in your reply, as I did not know Anandtech had tested not one or even two but three DS3's and a whopping 14 modules! So do you know if both the "c3" and "c4" use the Micron D9s, then? I've already ordered the 6400c4 kit, so I am getting the feeling I am in for a rude surprise!
I'm grateful to know that y'all are keeping ontop of the situation, this does go a long way to explaining the extremely large disparity in user results I've read or come across about the DS3. And I'm grateful Gigabyte is working to solve this issue, the user support and countless BIOS work from them is not something I was ever expecting... it's gone a long way to putting them on my top picks list.
And I believe I should be thanking you for the reply. ;)

-- on the second memory chart it always says "4/4 slots populated - 1 Dual-Channel Bank". If all four slots are populated with the same memory, why does it say "1" Dual-Channel Bank?-- I can only find the GEIL memory at one on-line merchant (via froogle or pricewatch) at $460 for 2GB. That would be $920 for 4GB! it would have been nice if you had also picked a less expensive memory that more of us could afford.
-- ASUS making a significant change to their product and only changing the version makes it VERY hard (impossible) to on-line order the specific product desired. newegg says order and if wrong, they will exchange...but that gets expensive too... and takes at least 7 days turnaround; and no guarantee that it will be the right one even then.
thanks for the article...it was, as always, full of useful data and observations.

1. The charts have been corrected. I stated this above but Jarred and I were editing at the same time on some pages and we did an overwrite on each other's corrections a couple of times. We learned our lesson after the Biostar section turned into the ASUS section. ;-)2. When we started this article the GEIL and G.Skill PC2-6400 that we used was in the $269~$289 range for a 2GB kit. This was far below the $500+ prices that our OCZ and Corsair memory modules had reached at that time. I am trying to create a memory table at this time as the boards were tested with everything from A-Data DDR2-533 to OCZ PC2-8000VX2. Our intentions were to use mid-range PC2-6400 memory when we started but it appears we chose some memory that is in very high demand and short supply now.
3. As I stated in the article, ASUS will probably call the 1.02G board something else. The 1.01G board is not a slacker. :)
Thank you for the comments, we appreciate them.

After going through about 4 or so of the motherboards and looking at their windows programs... I just gotta rant.Why in God's name must motherboard manufacturers make their programs SO UGLY? I'm no Martha Stewart, but even I can see that those programs are attrocious to look at and I actually don't install those cheesy programs because of how horrible they look. I prefer a normal streamlined windows look to my programs, hence why I use the Windows Classic theme. But even if your preference isn't a normal streamlined windows look, I don't see how anyone could find those horrid looking things called applications desirable.

it's Taiwanese tradition. For the people above... the S3 does not overclock as well as the DS3, it's very noticable. The DQ6 is in theory better than the DS3, but may hardly be noticable and when it is, it's probably just luck of the draw.My only criticism of the review is that only one memory module type was used and that I know other reviews on AT have included some other comparisons... but your review is more recent with more of the facts in(so more relevant). I know you had some references in the article and I know that the Micron chips are the best on average, but on occasion some chips perform better on a per board basis and not just on a per chipset basis.
Review does get 2 thumbs up from me though. The extra side information(EAX2 Support of onboard sound drivers, Micron D9 chips not fully supported, but will be, etc) helps make buying decisions. Thanks for the article!

Gah, how can such an ugly thing be tradition. It honestly detracts from the overall computing experience having something so tastelessly crafted. I guess to each his own :/
