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.

I am surprised I did not see this posted on a news site somewhere announcing Intel has a X6600. ;-) The line was corrected this morning to (X6800, E6700, E6600) although late last night my mind was probably thinking unlocked E6600 equals X6600 for some reason. Thanks for the notice! :)

In recent months the memory market has moved from a 1GB kit to a 2BG kit being the common memory configuration.2GB*
Excellent article, I'm assuming the OCing results were default voltages on the chipsets and/or the cpu?

To be honest, I would say it's quite different!
The storage controllers have been changed a lot... there is now a port-multiplier type of SiI chip that connects to one of the ICH7 ports, which provides driverless (!) RAID. Also, the previous board had a Marvell SATA/PATA controller instead of the JMicron controller.
For another difference: the new board is missing the PCIe 4x slot, too.
Anyway, thanks for the great overview! And it's amazing how fast after launch you got this up.

Thanks for your comment. We added information to the P5W-DH page with a little more info on the differences from the earlier board.nicolasb - Wednesday, July 19, 2006 - link
...is what is the actual impact on system performance of different memory speeds and timings? Possibly you guys actually derive a direct erotic thrill simply from knowing that your memory timings are 4-3-3-9 ;-) but what the rest of us care about is whether any given timings actually provide a tangible improvement to running applications. If I spend an extra £200 on memory, am I going to get an extra 10fs in a certain game, or just an extra 1fps if I'm lucky? That's what I want to know.Conroe is a new chip and it is by no means obvious (to me, anyway) whether the speed/latency of the memory will have a greater or lesser impact on the performance of the system than is the case for Netburst or A64 chips.
So, how about re-running some of your benchmarks on one particular board and producing results for different memory speeds and latencies?
Wesley Fink - Wednesday, July 19, 2006 - link
The original plan was to publish a Conroe memory article prior to this huge motherboard and memory roundup. The move forward of the Conroe launch by two weeks shifted our schedule quite a bit, as we discussed in the Buying Guide. we have found the timings DDR2 memory can achieve give a rough idea of the performance hierarchy on Conroe. That is 1067 at 4-4-4 is a bit faster than 800 at 3-3-3 is faster than 667 3-2-3. 667 is generally faster than nything slower regardless of timings.With 13 DDR2 kits it was impossible to do proper and complete performance testing on all the memory on Conroe and still deliver an article when you want to read it. There will definitely be followup reviews of memory on Conroe anwsering your questions in detail. We knew there would be complaints from some, but we also hoped you could understnad the roundup is posting 4 days after an early Conroe launch - and you can't even buy Core 2 Duo until 7/27 or later.
We wanted to provide solid info as soon as possible for those planning a Conroe purchase. We thought our finding that almost any Elpida value DDR2 will do DDR2-800 4-3-3 at about 2.2v was big news you would want to know, we will fill in the rest of the performance data as soon as we can.
As it is the roundup is over 15,000 words and one of the largest articles ever published at AT - in word length - and we really tried to be brief in each review. We really like giving our readers exactly what they want, but sometimes the realities of time and volume shift our priorities.

Although I can understand what you're saying, maybe the following should not have been included in the introductory page.I guess the only surprise was that the comparison wasn't there. :P
Honestly, I tried to jump right to that section only to find rather useless comparisons of ridiculously expensive memory (which I won't buy) and "value" (read cheap) memory (which I won't buy). Also, can you really tell me that it was much of a surprise that the expensive memory all topped out at roughly the same speed (~1100, 5-5/4-5-15)? Nor am I particularly surprised the value memory could overclock reasonably well, but how about tests of the memory that I think most of your readers are likely to buy? I've been looking at DDR2, and you can get memory rated at DDR2-800 for a little more than the DDR2-667/533 variety, and still a lot less than the DDR2-1000 modules.
I know that you were pressed for time, especially with the launch being pushed forward. I just think (and it is only an opinion) that other tests should have been given priority over the ones you've completed.

Also, what motherboard was used for the DDR tests? Often, value RAM is paired with a "value" motherboard. Value RAM may not look so well when paired with a value motherboard. I'm wondering how cheap we can go for reasonable peformance :)Gary Key - Wednesday, July 19, 2006 - link
We stated at the end of page 18 that we will be publishing performance results of the value memory roundup shortly. The amount of time required to test these seven modules at four different settings in several different applications was incredible and warrants a separate article update.
