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.

In all the features tables for the motherboards in this article the PCI slots are listed as being PCI v2.3. However, looking at the pictures for the boards, the slots have PCI v2.2 keying. I think the entry in the features tables is wrong. (Is it?)Patsoe - Saturday, October 28, 2006 - link
Seeing all the trouble with the P965 - especially with the non-intel p-ata controller and with the ich8r - I'd be inclined to get a Core2-ready i945P board with ICH7R instead. Would that be a sane idea?BadThad - Tuesday, October 24, 2006 - link
Is the v1.02G Asus P5B-E using all solid capacitors? I read a press release stating that Asus was releasing the "P4B-E Plus" version with all solid caps. Rumor says the "Plus" version will not be sold in the USA.....arrgggggg. Tell me that's not true. I want the solid caps for long-term reliability. I'm wondering if our "Plus" is actually the v1.02G?Thanks

The 1.01G and 1.02G boards are exactly the same except for a PLL controller. Asus stills states the P5B-Plus will not be imported into the States but you never know.keithke - Monday, October 23, 2006 - link
I was interested to hear you used this Scythe Infinity Air Cooler as I was going to do the same. Were there any issues with the Northbridge heatsink sitting so close? Or did it just plop right in with no spacing issues?Thx

No issues with the Inifinity on all four corners. It is a close fit but it works fine with the enclosed fan.SniperWulf - Monday, October 23, 2006 - link
Hey guys,Did you have any strange anomolies with the X-fi on the DS3 while overclocked? When I was using that board with the F6 bios, I'd have to reboot like 3-4 times before windows would properly detect it. I eventually grew tired of it and bought a P5B-D so I haven't had a chance to try F7 with it.

I did not have any issues with the X-FI on the DS3 when it was overclocked. The F5 and F6 BIOS releases were not X-FI friendly where F4 was perfect. F7 is working for some and not others, I did not have an issue with it. F8 will fix it for good.schlumpfi106 - Monday, October 23, 2006 - link
Im a little bit disappointed that there are so few informations about the cooling/silencing-related capabilitites of the boards. I would like to know how many fans can be connected, if the connectors are 3- or 4-pin, and if there is a way to control the fan speeds (preferably via SpeedFan). I don't care about a one-percent performance difference. My first priority is a reasonably silent system.goinginstyle - Monday, October 23, 2006 - link
He mentioned the number of fan headers on each board and even added a couple of comments on the ones that did not work right. In the features section there was a statement about whether the included utility worked or not. Sure he did not say anything about SpeedFan but how far do you want a guy to go after 26 pages? Also, if you click on the Enlarge picture on the boards you can clearly make out whether the fan headers are 3 or 4 pin.
