We were able to reach a final benchmark stable setting of 7x455FSB resulting in a clock speed of 3185MHz. This board is fully capable of near 500 FSB rates with correct memory support. This board has the same issue as the DS3 with most D9 Micron based 1GB modules not wanting to go above the 460FSB range in a stable manner. Our first screenshot shows the result of a beta BIOS that Gigabyte provided us which raised our FSB to 485 with our GEIL and Crucial memory.

Unlike previous testing with our DS3 we were able to drop our CPU voltage to 1.4250V compared to 1.4750V. The Vdroop on this board averaged around .01~.03V during testing. However, we had to increase our CPU voltage back to 1.4750V at our benchmark stable 7x485 FSB setting on this board. Our Gigabyte GA-965P-DS3 with the F8G beta BIOS was able to reach a maximum 505 FSB with the GEIL memory and 490 FSB with the Crucial memory although those settings were not completely benchmark stable. We expect to see the public release of these D9 friendly BIOS revisions in the near future.

We will take a look at how well our GEIL PC2-6400 memory operates in our S3 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, like Biostar, is fairly aggressive with their internal memory and MCH timings.

Gigabyte GA-965P-S3
Stable DDR2-800 Timings - 2 DIMMs
(2/4 slots populated - 1 Dual-Channel Bank)
Clock Speed: 800MHz
CAS Latency: 3
RAS to CAS Delay: 3
RAS Precharge: 3
RAS Cycle Time: 9
Voltage: 2.20V

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 DDR2-820 on this board and held timings of 3-4-3-9 up to DDR2-850 which is slightly lower than our DS3 settings. The board ran at 4-4-4-10 up to DDR2-860 before switching to the final overlclock settings of 4-4-4-12. We highly suggest the use of auto memory settings above DDR2-860 to ensure a stable system until you are able to fine tune the BIOS based upon your memory capability.

Gigabyte GA-965P-S3
Stable DDR2-800 Timings - 4 DIMMs
(4/4 slots populated - 2 Dual-Channel Bank)
Clock Speed: 800MHz
CAS Latency: 3
RAS to CAS Delay: 4
RAS Precharge: 4
RAS Cycle Time: 10
Voltage: 2.20V

Our settings of 3-4-4-10 at 2.20V were normal for the group and matched our Biostar P965PT board with both boards running tighter overall memory latencies than the ASUS or Abit offerings. We were able to keep this setting up to DDR2-820 before switching over to 4-4-3-10 settings that held stable until we reached DDR2-840. We then kept a setting of 4-4-4-12 at 2.30V up to our final overclock setting of 7x440, 3080MHz DDR2-880, with four DIMMS installed. This board should overclock higher with four DIMMs once the Micron D9 issue is solved.

    Yeah, WTF with the software design? Did they hire someone fired from FisherPrice or what? It's ugly and dysfunctional, even Asus AI Booster isn't THIS ugly.

    Regarding the article comment about the floppy connector,
    "We would just as well have this connector disappear at this time."
    you might want to clarify who "we" is, since there are plenty of people who want a floppy connector even if they don't have a constant use for a floppy drive.

    Remember that one person's use of a system does not equal entire world. Many legacy apps and even some emergency bios recovery routines require a floppy drive. If this were a reduced form factor board, it stands to reason that more features requiring connectors need to be left out, but to give up functionality on a whim is hardly useful, it's not as though you would have to grand replacement feature on that bottom edge, cubic inch of space otherwise.

    Oh my, do those motherboard monitoring/tuning applications look ugly... Ugly as in grotesque swollen blobs rather than functional design.

    A shame, I really liked the biostar board until the accompanying software utility appeared before for my eyes, aww... The gigabyte software is not pretty either... Can you switch the GUI to something less graphical and more standard windows widgets -like?

    Do all software accompanying motherboards look like this??

    You mean you actually use software to overclock? Do it the manly way and use the BIOS. Reply

    Its not about overclocking, the problem is if the motherboard software has some specific monitoring/adjusting features not available in freeware monitoring applications. Then you would have to use that monstrous software if you want the feature.

    Another problem is quality impression of the product as a whole. That software's user interface simply turns me off. Why don't they make the interface look like PRO tools, instead of plastic hell!

    I think it's great that, as mentioned in the first article, you are checking out the manufacturer's tech support by pretending to be regular joes rather than review sites. So I want to express interest in seeing more detail about how tech support treats you. ASUS seems to have gotten a bad reputation lately for tech support -- is this justified in your experience? I see that you say Gigabyte has been good so far. Thanks! Reply

    The 965 performs very well no matter what board it is on. I will be waiting till you get a 650i Ultra board to review. I am holding out on a Core Duo and my next purchase will be between these two chipsets. Reply

    Nice old school reference back to the double-mint twins. You definitely dated yourself with that one Gary.

    Not really, I saw a double mint advertisement on TV with twins the other day... Reply

    Really! I didn't know they had done a remake of that commercial.
