System Port Device Testing
Audio Subsystem Testing
Audio Playback Testing
Using a selection of Hard Rock and Heavy Metal music tracks and Windows Media Player, the audio subsystem playback performance was tested for playback accuracy and fidelity. Playback of the selected audio tracks was distortion free using a 5.1 speaker setup through the on-board analogue audio ports.
The audio subsystem performed well with no distortion detected during the music playback testing.
Microphone Port Testing
For testing the board's Microphone input port, a Labtec Desk Mic 524 microphone was used to capture a 30 second spoken phrase with the assistance of the Microsoft Sound Recorder application. The resulting audio file was saved to the desktop and played back using Windows Media Player
The recorded audio test resulted in clean audio pickup with no distortion or aberrant noise effects observed during playback of the recorded audio after adjusting the recording volume and Microphone Boost settings correctly. Audio pickup with almost inaudible with microphone recording volume set to less than 75 and Microphone Boost less than maximum (+30dB).
ATTO Disk Benchmark
To validate that the board’s device ports were functioning correctly, we connected an OCZ Vertex 3 90GB SATA III SSD to the system and ran the ATTO Disk Benchmark against the drive. ATTO was configured to test against transfer sizes from 0.5 to 8192 KB with Total Length set to 512 MB. The SSD selected for testing has a maximum read throughput of 550 MB/s and a write throughput of 500 MB/s on a SATA III port and a maximum read throughput of 280 MB/s and a write throughput of 260 MB/s on a SATA II port.
External device testing was done against the USB 2.0 and USB 3.0 ports using conversion cables to connect the SSD. For USB 3.0 testing, an Oyen Digital MiniPro™ eSATA / USB 3.0 Portable Hard Drive enclosure (rated for SATA III transfer speeds) was used. The SSD was connected to the internal SATA II and SATA III ports as well. The SATA device ports were set to work in AHCI mode in order to optimize SSD device operation. All tests were run 3 times with the highest repeatable read and write scores recorded in MB/s values.
According to various other testing sites, the real-world performance maximum of USB 2.0 peaks at 35-40MB/s (about 60% of its rated 60MB/s throughput and USB 3.0 peaks at 200-250MB/s on a SATA II based adapter and 250-325MB/s on a SATA III-based adapter. Note that USB 3.0 ports are rated for a maximum throughput of 350MB/s.
The USB 2.0 and 3.0 device ports performed within expectations with the USB 3.0 tests average equal to or above SATA II speeds for the connected device.
The drive performance on the Intel Z77-based ports pushed the SSD to its operational limits, while the ASMedia port operational speeds came in between SATA II and SATA III speeds. The speed difference seen between the ASMedia controller and the Intel Z77 controller is most likely because of the ASMedia controller's reliance on the shared PCI-Express bus.
SoftPerfect Research NetWorx Speed Test
In conjunction with Windows Performance Monitor, SoftPerfect Research NetWorx Speed Meter application was used to measure the upload and download performance of the motherboards integrated network controllers. Speed Meter was used to measure average network throughput in MB/s with Windows Performance Monitor used to measure average CPU utilization during the tests.
Killer GigE controller
For the wired network adapter, the testing consisted of copying two file sets from and to a remote system directly connected to the local system via a crossover cable. Use of a crossover cable eliminates the possibility of throughput loss due to router passage. The two file sets used consisted of a single 3 GB archive file and a folder containing 3 GB of audio files.
Note that that theoretical maximum throughput for a Gigabit Ethernet adapter is 125 MB/s (1.0 Gbps).
The average upload and download speeds of the Killer NIC were impressive with the large file tranfers coming in at over 90 MB/s for upload and an impressive 105 MB/s for download. However, its CPU utilization averaged higher than expected at 15-20%.

Very nice review of the MSI Z77A-GD65 gaming motherboard. I am thinking of buying one of these when I do my next build and i really appreciate the thorough article. Keep up the great work Morry!
Thank you. Glad to help.

I am curious… This is a gaming motherboard. So, I have to assume one would install a gaming video card. Is there a specific reason for the DVI and VGA ports on the back? Does the gamer actually use those ports?
I suppose one can connect other monitors up to those ports in a pinch, but does anybody use VGA any more?
Personally, I would rather see extra USB ports than a VGA port.
Thanks for the review,

Thanks for the review,
I just bought the GD65 standard board from Newegg yesterday (it was a bit cheaper than the gaming board and gave me 8 gigs or ram free). Aside from the better network chip and cooler paint job, is there any other difference?
Also MSI: support the PC Perspective Podcast! I exclusively bought from MSI as a thank you for their support(…and also I could not get Alex’s voice out of my head).

We didn't review the plain GD65, but from what I can tell from the GD65 specs, the differences are the paint job and coloration, heatsinks, Killer NIC, and inclusion of Sound Blaster software pack.

A dozen Los Angeles-area
A dozen Los Angeles-area residents—including the state’s second-largest biller for chiropractic services—were taken into custody Tuesday in connection with seven criminal cases alleging they cumulatively submitted more than $22 million in false billings to Medicare.
Those arrested also include a physician’s assistant and owners of durable medical equipment and ambulance companies, according to the U.S. Attorney’s Office.
In one of the cases, three defendants affiliated with Gardena-based ProMed Medical Transportation, an ambulance company, were charged with submitting more than $5.9 million in false claims to Medicare between 2008 and 2011.
ProMed’s owner, Yaroslav Proshak, 45, of Valley Village, general manager Sharetta Wallace, 35, of Inglewood, and office manager and biller Sergey Mumjian, 40, of West Hollywood submitted claims for medically unnecessary transportation services and then created fake documentation purporting to support those claims, the government alleges.
The charges filed in Los Angeles federal court are part of a nationwide crackdown by Medicare Fraud Strike Force operations in eight cities that led to charges against 89 people for their alleged participation in schemes to collectively submit about $223 million in phony claims to Medicare, federal prosecutors said.
The 12 Southland arrestees are among 13 defendants charged in Los Angeles in cases that allege health care fraud. The dozen either were arrested or surrendered to authorities after learning that they had been charged. The 13th defendant is a fugitive.
The defendants include Dr. Houshang Pavehzadeh, of the Sylmar Physician Medical Group, who allegedly billed Medicare more than $1.7 million for chiropractic treatments he never performed.
During the scheme, which ran from 2005 through 2012, Pavehzadeh, 40, of Agoura Hills, became the second-largest Medicare biller in California for chiropractic services—even though he was not in the United States when some of the services were performed, prosecutors allege.
In addition to being charged with health care fraud, Pavehzadeh is charged with aggravated identity theft related to Medicare beneficiaries whose information he used to bill Medicare as a part of the alleged scheme.
When investigators tried to conduct an audit of Pavehzadeh’s claims, he falsely reported to the Los Angeles Police Department that he had been carjacked and that patient files requested by the auditors had been stolen from his car, according to federal prosecutors.
Nine defendants affiliated with durable medical equipment companies were also charged in five separate indictments.
Olufunke Fadojutimi, 41, of Carson, a registered nurse; Ayodeji Temitayo Fatunmbi, 41, formerly of Carson, and now believed to be living in Nigeria; and Maritza Velazquez, 40, of Las Vegas, were charged with health care fraud.
The scheme allegedly revolved around Lutemi Medical Supplies, a company Fadojutimi owned and where Fatunmbi and Velazquez worked. According to the indictment in the case, Lutemi billed Medicare more than $8.3 million in claims, primarily for medically unnecessary power wheelchairs.
Fadojutimi and Fatunmbi allegedly laundered Medicare funds in order to purchase fraudulent prescriptions for the power wheelchairs and pay illegal kickbacks to recruit Medicare beneficiaries.
Fadojutimi and Velazquez was arrested today and Fatunmbi is currently a fugitive, according to the U.S. Attorney’s Office.
Susanna Artsruni, 45, of North Hollywood, and Erasmus Kotey, 76, of Montebello, a licensed physician’s assistant, allegedly worked together to commit health care fraud out of a medical clinic on Vermont Avenue where they both worked.
Kotey allegedly prescribed medically unnecessary equipment, including power wheelchairs, for Medicare beneficiaries. Many of those power wheelchair prescriptions were then used by Artsruni’s company, Mid-Valley Medical Supply, to support fraudulent claims to Medicare, prosecutors allege.
In only four months, the clinic and Mid-Valley billed Medicare more than $525,000 for the bogus claims, prosecutors allege.
Artsruni was previously convicted of health care fraud and was on pretrial supervision at the time she allegedly laundered some of the proceeds of the latest fraud.
Three other medical equipment cases were also brought, alleging fraudulent Medicare billing for medically unnecessary power wheelchairs that were sometimes never even delivered.
In one case, Akinola Afolabi, 53, of Long Beach, owner of Emmanuel Medical Supply, allegedly submitted more than $2.6 million in in false and fraudulent billing to Medicare.
In another case, Queen Anieze-Smith, 52, of Encino, and Abdul King- Garba, 47, of Westwood, owner-operators of ITC Medical Supply, allegedly submitted more than $1.8 million in false and fraudulent billing to Medicare, according to court documents.
In the third case, Clement Etim Aghedo, 53, of Fontana, owner of Ace Medical Supply Co., allegedly submitted more than $1.8 in false and fraudulent claims to Medicare.
The charge of health care fraud carries a potential maximum penalty of 10 years in federal prison; money laundering carries a potential 20 years in prison; and aggravated identity theft carries a mandatory two-year prison term.
