ASUS P8Z77-V Pro - In The Box
The ASUS P8Z77-V Pro retails at $225-$235, essentially $100 more than the ASRock Z77 Extreme4, so I would expect a good amount in the box to help sweeten the price point. Thankfully, we get a good amount!
Driver CD
User Manual
IO Panel
4 SATA Cables
SLI Finger
WiFi Go! 802.11 a/b/g/n WiFi card
WiFi magnetic antenna
USB and eSATA back panel
ASUS Q-Connectors
The addition of WiFi on the board obviously adds substantial value – personally, at home, I have my machines connected via WiFi, and ASUS say that at least 25% of their user base is in a similar position, hence the addition to the package.
Voltage Readings
Using OCCT we monitor the voltage change of the motherboard under load. This represents the direct correlation between the Load Line Calibration and how the processor/motherboard deals with voltage requests while under load. This is not to be confused with the quality of power delivery, but more an indication of how aggressive the default LLC settings are on a motherboard.
The ASUS board has regular power delivery, with minimal voltage ripple under load.
Overclocking
Note: Ivy Bridge does not overclock like Sandy Bridge. For a detailed report on the effect of voltage on Ivy Bridge (and thus temperatures and power draw), please read Undervolting and Overclocking on Ivy Bridge.
ASUS overclocking tools have been consistent over the few previous chipsets. In the BIOS, OC Tuner is a simple setting that enables a ‘Fast’ overclock on the system. Similarly, the TPU button on board does a similar action. In the OS, the TurboV Evo part of the software offers ‘Fast’ and ‘Extreme’ auto overclocking modes. For manual overclocking, the TurboV Evo software allows the user to play with an overclock in the OS, which should aid in setting a more permanent overclock in the BIOS.
Auto Overclock: ‘Fast’ mode (either through BIOS or OS) implements an immediate 19% overclock, with 41x on the multiplier and 102 MHz base frequency, ending with 4182 MHz overall. This is coupled with a memory overclock, which in my case it did XMP but backed off one memory strap. What was odd was that the memory was set to a 3T command rate!
‘Extreme’ mode implements a algorithmic testing tool in the OS to probe overclock limits. By slowly upping the multiplier and voltage, the system performs stability tests until the system crashes. The system reboots and then implements BCLK tuning, while still monitoring temperatures. In our test, the initial boot implemented a 20% overclock at 41x103 (4223 MHz), and then performed multiplier testing. At 47x, the system restarted to 46x and started BCLK tuning. At 104.5 MHz, the system restarted again, do a ‘Failed Overclock’ screen on boot. After pressing F1 for Setup, then F10 for Save and Exit, the operating system showed an overall 36% overclock – 46x103.8 (4774 MHz). At load, this gave 1.280 volts at load, giving an immense 94ºC peak temperature during PovRay. I do not think I would be happy with that temperature for a daily system.
Manual Overclock: With the overclock performance of Ivy Bridge processors being highly limited by temperature, having a low voltage is key along with hope that it does not compromise the overclock. In this case, I have started with 1.100 volts on the CPU and adjusting only the CPU multiplier to see what stable overclock we can get, before upping the voltage further. For this, PLL Overvoltage was also enabled.
At 1.100 volts, the highest multiplier that was stable was 45x, giving 4.5 GHz. This gave 68ºC at load with PovRay.
At 1.150 volts, the highest multiplier that was stable was 46x, giving 4.6 GHz. This gave 76ºC at load with PovRay.
At 1.200 volts, the highest multiplier that was stable was 47x, giving 4.7 GHz. This gave 83ºC with PovRay and 86ºC with OCCT. The system did boot at 48x, but gave 94ºC under PovRay as well as memory errors.

First off, thank you for the review.I am a bit bummed that the UD5H and the Z77 Deluxe were not reviewed, since those were the two I was looking at. Especially since the UD5H can be had for under $200.
Anyway, the voltage ripple/stability charts were quite interesting for me.
But my main concern lies with the Gigabyte's chart. It looks good... but in my eyes, TOO good. It's too perfectly straight. On one hand, I thought, "Wow, this board has awesome VRM or something."
On the other hand, it made me suspicious about why it was so stable. I have to ask, is it measuring the correct voltage?
The reason is because I had a similar finding when I was looking at the vcore requried to OC an IVB CPU (or any CPU, really) on the new Z77 mobos.
Per my thread here: http://forums.anandtech.com/showthread.php?t=22417...
We found that Gigabyte mobos were incorrectly reporting its VTT voltage as the vCore, which resulted in "vcore" readings in CPU-Z and other programs reporting the same, or very similar, 1.0xx voltages regardless of what the CPU OC'd to.
I hope to be able to get some clarification on this.
Only other suggestion I have is to really test more of the features of each motherboard. (mSATA, firewire, audio, etc; how do they compare with other chipsets, how are their drivers, etc..)
Thank you, and keep up the good work!

Hi DarkRogue,I have the Deluxe on my test bed right now, so keep your eyes peeled for when I finish the review.
Regarding the voltage reading charts, it merely reads the OS reported voltage. This is loosely a smoothing of what ripple actually happens on board. After consideration, it only serves to show LLC on board, and how the board reacts to requested load by the processor. It's fairly easy for a manufacturer to override this to make sure only a straight line is reported. But, if it is a messy line, then there could be a problem (e.g. check my 990FX review a little while ago).
I'd love the kit to test more features on the boards (mSATA etc), if you've got any kit spare! :) Though keep in mind that each test can't take 2 hrs, or we would end up with 1 board a month reviewed (as we do this part time)! I'm open to suggestions regarding tests if anyone has a good one with a simple output I can report and analyse.

Thank you for your response, Ian!I wish I had the funds to send in spare items, though. Unfortunately, I'm not quite rich enough, haha. We'll have to be bound by the generosity of the various vendors to this site.
As far as tests go, I imagine some people would be interested in a quick RMAA test of the various audio chipsets. It's of no concern to me, since I insist onboard solutions are never going to be as good as a dedicated external DAC+amp, but it should be good for a lot of people.
I'd also be interested in how the eSATA and Firewire performs, as I'm of the camp that says anything firewire related that isn't Texas Instruments is not worthwhile. The eSATA, mainly it's to see if there are any quirks with the drivers from each manufacturer allowing hotswap properly or not, and whether it causes DPC latency issues. My friend's ASUS board was plagued with problems related to eSATA not allowing him to eject drives, BSOD'ing on resuming from sleep, causing massive DPC latency when a drive was connected, etc. It's these little things that really make or break the experience of a board.
I'd also like to see how well the fan controls are on each motherboard. ASUS' Fan Xpert 2 really drew me in, as it seems no one else can match the level of customization for fans. I dug a bit and found out that Gigabyte's boards not only cannot do this, but it even struggles to stay consistent between its various headers. (One header runs straight +12v no matter what, while the others make the fans spin at different speeds with the same settings.)
ANYWAY, back to the issue at hand - Gigabyte's voltage readings.
As I found in my thread linked above, Gigabyte appears to be reporting the wrong voltage, for some unknown reason. This to me seems to invalidate the test result for the Gigabyte board, because it's incomparable to the others.
I know that the purpose of the test is to test for variation in the voltage to the CPU, not necessarily the exact ripples, but the VTT supplies voltage to a completely different segment than the vcore, unless I'm mistaken. I wouldn't think that the voltage supplied toward the IMC would vary as much when the CPU ramps up and down.
Is there a way to force that program to probe a specific/different voltage reading, or have you already done this and the chart actually does represent Gigabyte's handling of vcore voltage? I wasn't able to figure that out from the article.
Thank you again!

Thank you so much for covering the fan control features on each board! I truly appreciate this as it is often left out in other reviews.Keep up the great work!

I don't know about anyone else, but I'm really sick of seeing VGA and PS/2 ports wasting space on new motherboads.I know some gamers might think that PS/2 does the job better than USB, and I can appreciate that, but VGA? Who even uses VGA connections anymore? They should be avoided like the plague.
And even if you do insist on using a VGA connection, what's the point of putting a DVI-D connector and a VGA together? Chances are you won't be using both, so just make it a DVI-I connector and throw in one of the cheap DVI>VGA adapters, and use the newly freed up space for a connector that isn't an ancient piece of garbage. Let's see HDMI or DP up there. Move things around so you can perhaps throw an eSATA connector on the back, or more USB ports--you can never have too many USB ports!

PS/2 has one single thing that makes it superior to USB: you can turn your computer on by clicking space bar on a PS/2 keyboard or clicking mouse button on a PS/2 mouse. USB does not have this feature which is a big problem if your computer case is not easily reachable.Agree about VGA ports. Nobody uses them anymore. Nobody.
AeroRob - Wednesday, May 9, 2012 - link
As I understand it, gamers feel there's an issue with USB's polling rate, and prefer PS/2 for that reason.As for turning on your computer, I never heard about that. I rarely shut my computer completely off, and my wireless USB keyboard can wake it up from sleep just fine. Hell, my computer's so sensitive to any change, just flipping my monitor back on wakes it up (probably due to the built-in USB hub).

I know whole organizations that still use VGA, and there are tons of KVM switch boxes in development and testing centres everywhere that only support VGA. Yes I know you can get HDMI and DVI KVM's but most places won't have them yet.I still use VGA occasionally and would be annoyed if it wasn't there.

And how many of those organizations are switching to Z77 boards and still keeping their VGA?Ramon Zarat - Tuesday, May 8, 2012 - link
The latest AXTU version does not include XFastRAM anymore. XFastRAM is a stand alone utility now. Also, XFastRAM is much more than a 32bit 4GB RAM limitation extender. It's in fact a RAM disk on steroid, valid for both 32 and 64bit system. It can do the following:1- "Recycle" unused memory beyond 4GB on a 32bit OS into a RAM disk. A RAM disk of up to 32GB can be created on a 32bit OS.
2- RAM disk of up to 8GB on a 64bit OS. Asrock is working on extending that limit on 64bit OS.
3- Can choose any available driver letter to assign to your RAM disk
4- Use part of the RAM disk as a Readyboost drive to accelerate your magnetic boot drive!
5- Easy transfer of either or both the "user" and "system" temp file to RAM disk. No fooling around with Windows configuration.
6- Easy transfer of IE and Firefox cache to RAM disk. XFastRAM take care of everything straight from its interface.
7- Easy transfer of the page file to RAM disk. Again, directly from XFastRAM interface.
8- Possibility to save the RAM disk to hard drive before shutting the PC down.
It's fast (10 000MB/s with CrystalDiskMark on a 2500K @ 4.7 and 8GB of 1866 RAM) , it's free, it's amazingly flexible and can both accelerate your PC and prevent premature wear on your SSD by redirecting a lots of small writes to the temp folders and web cache! You can apparently gain 5X performance in some Photoshop operations when you configure it so use the RAM disk as the temp folder!
