Biostar TForce P965 Deluxe: Overclocking
FSB Overclocking Results
We were easily able to reach a final setting of 7x500FSB resulting in a clock speed of 3500MHz. We know the board can do better but the BIOS is locked at a 500FSB maximum currently. We were able to run at a very acceptable 1.475V at this setting with Vdroop being around .02~.03V during load testing. We were also able to run our memory at 4-4-4-12 at 2.2V on this board. We thoroughly enjoyed the overclocking aspects of this board as it only took a couple of reboots to get the system dialed in for our benchmark testing.
Memory Stress Testing
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. Biostar implements slightly tigher memory and MCH timings than the ASUS or Abit resulting in minor performance differences in our benchmark testing.
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 DDR2-840 on this board along with timings of 3-4-4-9 up to DDR2-860. The board ran at 4-4-3-10 up to DDR2-920 before switching to the final overlclock settings of 4-4-4-12.
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 due to tighter overall memory latencies the benchmarks were slightly improved across the board. We were able to keep this setting up to DDR2-830 before switching over to 4-4-3-10 settings that held stable until we reached DDR2-900. We then kept a setting of 4-4-4-12 at 2.20V up to our final overclock setting of 7x478, 3346MHz, with four DIMMs installed.

Oh, trust me, Gary tested with a LOT of RAM types and manufacturers. However, for the *benchmarks* he settled on one specific set of DIMMs. I think he's trying to put together some information on how the various boards worked with other RAM (see above comment from Gary). Cheers!stmok - Saturday, October 21, 2006 - link
LOL...I think its more like: "What the hell were the Abit engineers thinking?!"Based on your experiences, do you know if the Analog Devices AD1988A HD Audio Codec works in Linux? I wouldn't mind going for the ASUS P5B-E at the end of the year.
And finally, is the rev 1.02G mobo available now? Or in a few months time?
Gary Key - Saturday, October 21, 2006 - link
The 1.09 ADI AD1988A drivers worked fine in SUSE 10.1. Realtek has better support at this time but ADI seems to be catching up. Believe it or not, but we booted every board with SUSE 10.1 just to make sure they went to the desktop. We might even do a once in a while look at Linux down the road.

what is the range of overclocking possible with pc6400 ram?without dividers? with dividers?
Gary Key - Saturday, October 21, 2006 - link
Good question, depends on the PC2-6400 RAM. We are working on something right now to answer your question with a few different modules.xsilver - Sunday, October 22, 2006 - link
probably something standard like corsair VS or something priced very similar if there is better performance elsewherexsilver - Sunday, October 22, 2006 - link
also I would assume that 1gig vs. 2gig makes no difference but if it does, it would be good to know.Madellga - Saturday, October 21, 2006 - link
Excellent review Gary. I also look forward for the round 2 and also for a 975/ATI/Nvidia reviews.Please try to mention the Vmch used for the overclocking results, as this says a lot about the motherboads also.

I am setting up a overclocking settings table and will try to show some additional results with different memory types that we used in testing. I have no idea when this will be finished. ;-)Ryan Norton - Saturday, October 21, 2006 - link
This article is terrific-- now I just need to read the high-end part and I can finally put together a Core 2 Duo system.Will the DS4 be included in the high-end guide? I don't want a DQ-6 because the copper backplate under the processor socket would prevent installation of a Scythe Ninja heatsink.
Are the AHCI issues going to stay the way they are, with needing to load the drivers from a floppy disk during Windows install, or are there any P965 boards that don't require "an engineering degree and a day off" as you guys said?
