Biostar TPower i55 – Super Middle Weight Contender

Performance Summary
Performance is indistinguishable from other P55 motherboards - these products all perform about the same at stock or even overclocked speeds:
Biostar provides a great PWM/FET design for stability and overclocking, which also results in very good power consumption results..
Of course, one of the key questions that invariably comes up in regards to a board’s performance capability is just how well it overclocks.
Core i5/750 8GB Results -
Gary had excellent results with his retail processors on this board in both 4GB and 8GB configurations. His primary problem encountered during overclocking with all three processors was the inability of the board to hold tight sub-timings with 8GB of memory above DDR3-2000. While the board would easily clock 8GB up to DDR3-2200 with 1.66V VDimm and VTT around 1.38V, we usually had to run CAS9 timings and loosen tFAW and B2B slightly to retain memory stability.
The Everest results show read/copy rates being up to 20% lower than a 4GB configuration at like timings, indicating Biostar still has some MSR/MRC tuning to complete in the BIOS. However, actual performance in games and applications never varied by more than 1%, so in some ways it just does not matter that much unless you are comparing synthetic benchmarks.
With all three processors, we never had to increase CPU PLL or the PCH voltages. VDimm was kept at 1.66V, VTT at 1.34V~1.38V, and VCore load voltages differed slightly between processors. Our i5-750 required 1.360V for 4.1GHz, i7-860 needed 1.425V for 4.3GHz, and the i7-870 hit 4.4GHz with 1.4V. Interestingly enough, our i5-750 would top out right around 4.1GHz regardless of voltages or cooling.
Core i7/860 and i7/870 8GB Results-
We had absolutely no problems clocking our i7/860 to 4.3GHz and the i7/870 to 4.4GHz with 8GB of memory.
Just for fun, we pulled out our “cherry” i7-870 ES sample just to see what we could do on air in a suicide run for a screenshot. For the first time in our P55 testing, we were able to POST, enter Win7 x64, and take a few screenshots above 5GHz. The system was even stable enough to run SuperPi 1M, but not much else, in fact, just starting the Crysis or PCMark Vantage benchmarks would lock the system. However, it just goes to show that this board is capable of high overclocks for the vast majority of users on air or water cooling. Our maximum stable Bclk rate on air was 220.
If you want more details on the Biostar TPower i55, please continue on.

Rajinder, is there any way to differentiate the new foxconn sockets from the old (serial/part numbers, a visual difference between the two)?Rajinder Gill - Thursday, November 26, 2009 - link
Hi Joe,None that I know of I'm afraid. If I do find anything out, I'll update.

In your great overclocking section I see you have once again exceeded the 1.21v Intel recommended Vtt specification (by a fair amount). Is this something you would be comfortable with for 24/7 running or is this just to demonstrate the limits of the board?I have no real concept of why the Vtt spec has changed from Bloomfield but if I were running a P55 system overclocked 24/7 I suspect I couldn't expect to reach a 4+GHz overclock - it would be limited by 'safe' voltage.

The Intel voltage specifications are given out in relation to stock operating frequencies. Increase freqeuncy and you increase power, so if you're really following Intel guidelines, then you need to observe stock operating frequencies too.There is no definative answer to what kind of degredation a CPU will experience due to elevated voltage/current long term. One can assume that the degredation will be faster, but whether or not that will be a factor for the end-user is another matter. Of course, too much voltage is certainly asking for trouble. We generally run stuff just to show what the board can do. At least it answers the question for people who like to push hard. At the same time, if the board is stable at higher operating frequencies, the more sensible stuff is ceratinly possible.

I always find that the most relevant information to me is left out of every motherboard review.Benchmarks for motherboards are always very similar, in fact, they are so similar that in my opinion, aren't worth mentioning. If there is a strange issue with USB speeds being low (which I've seen before), then that probably is the only benchmark that really needs any type of graph. Do people really care if the board A gets a 1KBPS higher score on the network test than board B? I'm sure this is well within the margin of error of the test anyway. This may be what you're getting at when you guys have switched the conclusion to the first page of the review, which I thought was a good decision.
Relevant information that always seems to be missing:
1) Are the fan headers able to be controlled by bios? If so, how and how well? Can they all be controlled or just a few? Sometimes it specifies, but it fails to provide any real details.
2) The audio chip. Realtek did a wonderful job at creating 'optional' features on a few of their codec’s. I bought the MSI P55-GD65 board on launch date and assumed it could do real time DDL encoding (like my old gigabyte P45-UD3P which uses the same audio codec), little did I know, that this optional feature is disabled. Apparently 'true blue ray audio' doesn't really mean much. A simple paragraph about the audio chip's capabilities would be nice. Especially since some motherboards use VIA's codec’s which tend to be even more confusing than Realtek's.
3) Strange things such as mentioning who makes the chip for the NIC and other random things would be nice. For some reason, I have a good bias towards Marvell NICs. This information seems to be included more often lately :D
4) Information about how board features are integrated into the motherboard. Is that gigabyte NIC running off a PCI-E lane or PCI?
5) Useful information about strange features such TPM headers (which you made no mention of in the MSI P55-GD65).
Specifically for this review, it is said that this board is trying to compete with the MSI P55-GD65 and you say it has an advantage even though it is more expensive ($25-$45 more). How though? It is never really said. Both boards perform identically (in fact, probably any P55 board will perform identically to another. . .) and both have similar layouts. The MSI board has 1 more PCI-E slot along with an open slot PCI-E x4. How is this not an advantage? Both have dual NICs, 2 more SATA2 ports (with the MSI board having a better solution imo - the single blue slot on the board is useful for a disk drive leaving the entire 6x SATA2 ports on the P55 chipset for some type(s) or RAID) and digital audio.
Also, a complete guess, but board designers probably still include the floppy drive header just because its included in the chip they use for IDE and additional SATA (maybe jmicron doesn't make a chip that is just IDE/SATA instead of IDE/SATA/floppy), or maybe they just cost the same. . .

"Test Setup" is a big missing for me. What are you calling an "Intel P55" on these charts or all the Intel P55 motherboards from $90-$240 the same performance?g725s - Wednesday, December 2, 2009 - link
Cool conclusion on first page. Keep it up!Rajinder Gill - Wednesday, December 2, 2009 - link
Some seem to like it while others are not impressed (check the firs page of comments). I'll probably do some kind of exec front page summary in the future.later

FWIW, I like it. Interestingly to me, it's essentially the same layout and format that I use for my testing an analysis at work, so I actually feel sort of vindicated. :-)treesloth - Monday, December 7, 2009 - link
