Biostar TForce P965 Deluxe
Basic Features
Biostar has delivered a basic but performance oriented P965 board that should sell for around US $135 or under. While our board and BIOS are from the first production run, we were surprised after dealing with our other P965 based boards at how stable and generally dialed in this board is right now. Although we certainly believe that future BIOS releases will extract additional performance from this board, it was nice to boot up this board and have it just plain work as advertised. This board did not require a BIOS of the day or week to work with various Conroe steppings or to address memory performance and stability issues.
The layout of the board is very nice with a double slot next to the PCIe X16 connector that allows the use of dual slot GPU cards without losing either a PCIe or PCI connector. We think Biostar provided the right combination of PCIe and PCI slots for today's market considerations. While the 24-pin ATX power connection is in an awkward position, Biostar stated this was the best possible location for stable power delivery, and we are seeing this location utilized more and more on other P965 and 975X boards now. The floppy drive connector is also located at the opposite end of the board and for those still using this type of drive it will create a cabling issue. Overall, we like the general layout and options on this board.
Basic Performance
The performance of the board was at times in the upper segment of our roundup and at others near the bottom when excluding the ASRock value board. We found the board to be a very consistent performer and extremely stable up to its limit. Unfortunately, we do not know what the true limit of this board will be until we see further BIOS optimizations and improvements in the memory voltages. As with recent Biostar boards in the new TForce series, we see significant BIOS options available for the performance oriented crowd yet they have once again let us down on memory voltages.
This board only supports up to 2.2V and only allows four total memory voltage choices. Without additional memory voltages up to 2.4V that we see in the majority of boards being released at this time, it was impossible to really push our memory and improve the overall performance of the board when overclocking. We once again contacted Biostar and chastised them for this omission. One could argue that a board in this market sector would probably not require higher memory voltages but a board being marketed for the performance user should include voltages up to 2.4V along with additional adjustments. The balance of the BIOS is obviously tailored for this type of user and unlike others we have tested this BIOS was stable and almost error free for a first release.
We still believe overall that this board is a great value at this time and offers what appears to be the best blend of performance and price in our roundup. While Gigabyte, Foxconn, ECS, Abit, and others have released or are in the process of releasing mainstream P965 boards, we congratulate Biostar for having a board of this quality available quickly.
Overclocking
We were quite surprised by our overclocking results on this board but we did have to gradually increase the FSB speeds and alter the memory settings in order to reach this level. While this is generally indicative of a board at its limits, we believe part of the hunt and search activities that were required are due to a BIOS designed for stability/compatibility first with hopefully the inevitable performance tuning coming in the next revision.
When we installed our X6800 and started testing for maximum FSB overclocking we were treated with a 9x379 result that indicates additional headroom is available on this board and hopefully the board will reward us with higher overclocks in the next BIOS revision, so we might find the true FSB ceiling on the board to be near 380.

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)
