Test Setup -
We utilized a wide variety of memory kits from Corsair, OCZ, Patriot, GSkill, and Kingston to verify memory compatibility on our test boards. Our OS and primary applications are loaded on the Kingston 80GB SSD drive and our games operate off the WD 300GB VRaptor drive. We did a clean install of the OS and applications for each motherboard.
We chose the ASUS GTX275 video card and Corsair’s 750HX power supply. Our air cooler of choice is Thermalright’s Ultra 120 eXtreme, primarily for its exceptional performance during our overclocking tests. We also tested with the retail cooler and those results along with direct CPU comparisons can be found here.
Our 790FX/X58 results are provided for comparison only. For our test results we setup each board as closely as possible in regards to memory timings. Otherwise all other settings are left on auto. The P55 and 790FX motherboards utilized 8GB of DDR3, while the X58 platform contained 6GB. The P55 and X58 DDR3 timings were set to 7-7-7-20 1T at DDR3-1600 for the i7/920, i7/870, and i7/860 processors at both stock and overclocked CPU settings.
We used DDR3-1333 6-6-6-18 1T timings for the i5/750 stock setup as DDR3-1600 is not natively supported in current BIOS releases for this processor at a stock Bclk setting of 133. We had early BIOS releases that offered the native 1600 setting but stability was a serious problem and support was pulled for the time being. Performance is essentially the same between the two settings.
The AMD 790FX setup is slightly different as trying to run DDR3-1600 at CAS 7 timings on the 1:4 divider is extremely difficult. Without resorting to some serious overvolting and relaxing of sub-timings, we set our AMD board up at DDR3-1600 8-8-8-20 1T timings but with NB speed at 2200. The difference in performance between C7 and C8 DDR3-1600 is practically immeasurable in applications and games on this platform.

I want to know how why the AMD board murders the rest in two games when it's in it's more usual 'bringing up the rear' position in the rest.ta2 - Monday, November 30, 2009 - link
Seems like you've been using a pretty crappy i5 chip. For it to top out as 4.1GHz is incredibly bad. I manage 4GHz on a GA-P55-UD4 with ALL voltages at stock except VCore at 1.30V. You have not really pushed the BCLK on this board and for you to need 1.36V for 4.1GHz is pretty terrible. I consider myself a novice overclocker, but either you're using a very bad chip or this board isn't so hot."We could run our memory at DDR3-2152". This board is officially rated up to 2600MHz for memory... so we haven't even tried to get close to the spec speed.

It's an average 750 CPU. There are plenty out there that top out early.With regards to 2600 MHz memory, I don't know of any CPU's that can hold 2600MHz speeds fully application stable. That's a benchmarking claim for users who run processors with sub zero cooling or like to post suicide shots. This article is focused on daily PC use. A BCLK of 215 is perfectly respectable for everyday usage scenarios (especialy with S3 resume working).

The board looks really awesome. I mean, the fact one of the main gripes is the lack of clear CMOS button in the rear I/O panel says a lot. I like that Biostar used the Intel ethernet PHY to take advantage of ICH10R's built-in network controller. So many times I see CPU usages going 20~30% when there is heavy network trafficking, and I wondered why my experiences are so different from what I see in the reviews. Granted different packets show different performance characteristics and anti-virus is probably half of that CPU load, but the CPU usage wasn't as severe on my BadAxe 2 (which I use for WHS) so I do believe the Intel NIC/PHY is superior to that of Realtek.Another welcome news is the flawless S3 functionality under overclocking, and I applaud it very, very much. Board's layout looks extremely clean and logical as well. For me the downside of this board are the lack of fan headers and the price tag which can be (hopefully) rectified in the future.
Thank you for a thorough review (for a split second I thought Gary was the author, but please don't take offense ;) ) and I just might have found my next motherboard.

Well, actually I do have one more gripe. I am not a fan of daisy chained heatsinks, and on this board the heatsink with 'Biostar' written on it kinda sticks out. I'm guessing what's underneath are those 4 PCIe blocks often found bare on other boards. (?) How hot do they get and do you think it's justified to having a heatsink over it based on that? If not, I'd prefer to have more room for CPU HSF installation and video card installation.Rajinder Gill - Saturday, November 28, 2009 - link
Hi,The BIOSTAR logo sink does not really cover anything other than to add mass to the enitire assembly. Stock operating conditions, you could get away with passive use. If overclocking and raising PWM switching frequency(for whatever reason), while runnign a 'hot' GPU in the first slot, you'll probably want to cool the HS assembly depending on what kind of case you have. The lack of fan headers obviously does not help.

Thank you for the clarification. That said, since the board is kind of heavy on use of heatsinks, maybe they can use real screws instead of plastic push-pins? Faced with the Almighty AnandTech editors' advice, who knows? Biostar might listen. *wink* *wink*yuhong - Friday, November 27, 2009 - link
"It’s the first time in a long time we’ve not had to request fixes for peripherals or BIOS issues/tweaks to complete a benchmark, a welcome change indeed!"Yep, remember this:
