LAN Speed Test
LAN Speed Test is a freeware program designed for testing the network connection between two PCs on a home network. The speed of the transfer is limited by the lowest common denominator on the network, so if you have gigabit Ethernet capable computers but a 100 Mbit capable router, you are limited to 100 Mbit transfer. Note that this is really a formality – if a network port is rated at 1 Gbps, then chances are that it might hit at least 90+% of this value. The main test here is CPU usage, and how much is offloaded by the controller. For this test, we use LAN Speed Test to transfer a 1000 x 1 MB files across a home network with a 1 Gbps lowest common speed to the same machine each time, in a read/write scenario. Results are taken as peak speeds from several runs.
USB Speed
For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 240 GB OCZ Vertex3 SSD with a SATA 6 Gbps to USB 3.0 converter. Then we transfer a set size of files from the SSD to the USB drive using DiskBench, which monitors the time taken to transfer. The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are the videos used in the Sorenson Squeeze test.
Due to the lack of Gigabyte USB 2.0 back panel ports, no results for the Gigabyte board were able to be fairly taken. In comparison, the XFast result from ASRock seems to speed ahead of the others.
As this test deals with incompressible data at a Queue Depth of 1, UASP makes a difference in read but not in write. The adaptations performed by XFast are clear to see at this level.
SATA Testing
We also use CrystalDiskMark for SATA port testing on a C300 drive. The sequential test (incompressible data) is run at the 5 x 1000 MB level. This test probes the efficiency of the data delivery system between the chipset and the drive, or in the case of additional SATA ports provided by a third party controller, the efficiency between the controller, the chipset and the drive.
The MSI board seems to come out last in all our SATA testing.
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line. Therefore, if the audio device requires data, it will have to wait until the request is processed before the buffer is filled. If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks. Having a bigger buffer and correctly implemented system drivers obviously helps in this regard. The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - less than 500 microseconds usually gets the green light, but the lower the better.
All the motherboards using Ivy Bridge chips do particularly well in our DPC test (as you would expect), with all boards coming in at under a very respectable 120 microseconds. The ASUS goes one step further with our lowest DPC score ever at 60 microseconds.

Having RAID Option ROM Supported in UEFI as well (people using RAID) is a very good thing ASRock have done with their Z77 series, wonder when Gigabyte will add this feature, http://www.youtube.com/watch?v=Y1TbdVtAE9cgramboh - Tuesday, May 8, 2012 - link
Just wanted to add that my new P8Z77-V Pro POSTS significantly faster than what Ian experienced in this review, probably due to my configuration:Intel SATA: AHCI
ASmedia USB3: on
ASmedia SATA controller: off
Wifi: off
Onboard sound: off
My total time from splash screen to Windows 7 Pro x64 login is 15 seconds on a Mushkin Chronos Deluxe 240GB. The post is about 6 seconds (hand timing these). It's unfortunately the other controllers add ~14 seconds of POST time.

Hi Gramboh,Disabling ASMedia SATA, Wifi and Sound would obviously decrease POST time by quite a bit! As I doubt the majority of non-enthusiast buyers would go into the BIOS and disable what they don't need, I kept the start up sequence the same as default to reflect this.

A large number of your readers are enthusiasts. Giving both sets of numbers would be beneficial for us. A per onboard device breakdown of boot time would be nice; but probably too much work to be justified.IanCutress - Tuesday, May 8, 2012 - link
I've added 'POST Quick' to my internal database of testing, with the aim to turn off all I can to observe POST times. Will be applied from the next review onwards, perhaps retroactively if I get time.Ian

Awesome, thank you so much!Perhaps the manufacturers will pay attention to this too :-)

I think most Anandtech readers DO go to BIOS to set things up. I think it is crucial to know if the differences in performance (boot time, benchmarks, power consumption etc) can be minimized just by changing BIOS settings. That would make it a lot easier to buy a new board.I have seen reports that some boards don't follow the Intel specs regarding Turbo Boost settings and utilize higher frequency with all cores utilized. This skews the performance results greatly. Those following the specs get worse results - yet they could be configured for exact same performance.

Makes me really glad to have ordered the ASRock, though I wonder how it would be affected by having RAID enabled? My GA-P35C-DS3R takes about a minute to get through POST and RAID screens.I am also confused why even the quick one is taking so long. My laptops take less than 5 secs to POST :/

ATX just seems like it's for bragging rights, and not even directly so, simply because you'll be able to say you have so many things connected, maybe you even have tri or quad SLI, all in a huge case. Can we get some coverage of mATX boards?On another note, something that drives me nuts is the AHCI driver loading at POST. Last time I checked I couldn't find a straight answer, does this loading stage still happen in ivy bridge? Of course you don't have to use AHCI, but it really should be standard and enabled by default. At least for anyone spending this much on a motherboard.

"Conclusion – Gigabyte MSI Z77A-GD65"One more rant lol. Is having all 4 video outputs really a feature? Is this not targeted at people who will be using their own graphics card? In which case they only serve to use up space that could be used towards USB ports or something else that's almost as useful. Remember before P55, 10 usb ports were starting to be the average on a feature filled board, now we have to settle for 6-8. Unless you want to spend top dollar for more.
