ASRock Z77 Extreme4 - In The Box
Driver CD
User Manual
IO Shield
2 locking SATA cables
3-slot SLI bridge
Uncharacteristically from ASRock, we do not have a lot to shout about regarding the contents of the box. Previously with the P67 products we had a USB 3.0 bracket, but this time we are limited to just a pair of SATA cables. This is unfortunate, but perhaps was required to hit a price point.
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 CPU voltage at load for the ASRock board seems to vary more than the other boards in this review, which may be a result of the price difference. Nevertheless, this is not a series of massive jumps to be concerned over.
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.
As the first explanation of overclocking results on a platform, I would highly suggest you read my article on overclocking performance on Ivy Bridge. As the successor to Sandy Bridge, people may expect similar to Sandy Bridge. However, there are a number of key differences, especially in terms of heat generation and applied voltages.
Auto Overclocking: ASRock comes with several automatic overclocking features, however these are all in the BIOS – ‘Enhanced Turbo 30’ and ‘Optimized CPU Setting’. Enhanced Turbo 30 initially calls upon preloaded settings – 4.7 GHz on the CPU, 1600 MHz on the iGPU, +0.085 volt offset on the CPU and CPU load line calibration (LLC) set at ‘Level 1’. This setting did not do anything to the memory, and made the machine run rather hot – 92ºC during OCCT causing it to stop, and 97ºC during PovRay. Both of these temperatures were on the test bed outside a case, so I would not recommend them inside a case!
The Optimized CPU Settings offers CPU speeds in 200 MHz increments. When selected, it adjusts the CPU multiplier but leaves all else on automatic.
- At the 4.4 GHz setting, this gave 1.112 volts on load, 72ºC during PovRay and 70ºC for Blender.
- At the 4.6 GHz setting, this gave 1.192 volts on load, 85ºC during PovRay and 86ºC for OCCT.
- At the 4.8 GHz setting, this gave 1.240 volts constant at LLC Level 1. This caused the blue screen of death on boot.
Manual Overclocking: Given the overview of overclocking on Ivy Bridge, choosing your maximum voltage to aim for a speed is critical. The best combination I achieved on the ASRock Z77 Extreme4 was 4.7 GHz at 1.175 volts, using LLC Level 1. This gave 86ºC during both PovRay and OCCT, which is essentially near the limit as to what I would suggest on Ivy Bridge.

Don't intelligently designed modern operating systems use as much unused RAM as is available as filesystem cache? I know Linux does, I would expect Windows 7 does as well. In which case, I have to wonder what the value of a RAM disk except to make your persisted data completely volatile and lost on a power outage.Turning the unusable RAM beyond 4 GB into a RAM disk when a 32 bit operating system is in use is the only marginally useful feature that you mentioned, but you have to be stuck with a 32 bit OS for that to be of any value.
Using a RAM disk comes at the cost of vastly increased complexity for managing persisted files (having to copy things from RAM disk to persistent storage before shutting down) and vastly increased risk of loss of data on unexpected power outage. All of the RAM disk useability features in the world won't help with those issues.

Temp, cache or scratch files would be good uses of a ramdisk. Other than that, there's really no point.kstan12 - Tuesday, May 8, 2012 - link
i would *love* to read a review of ivy bridge that doesn't include an engineering sample. my i7-3770k seems to want a lot more voltage @ 4.7 than what i see in reviews online. i know one might clock higher than another but it seems these ES samples use less voltage. am i wrong here?and where did you get the updated bios for the asus p8z77-v pro? i can only download 0906. :-)

Hi Kstan12,My ES is stepping 9, which is identical to retail. It's all about the luck of the silicon at the end of the day.

oh ok, so you would just compare the stepping, thanks! maybe i'm not so good at overclocking too.love reading your articles...you explain things quite well, good work!

Unless you bought it retail, they could have easily given you a cherry-picked chip. There is a lot of variation in semiconductor manufacturing, even on the same stepping.Zoomer - Tuesday, May 15, 2012 - link
If that's the results from a cherry picked chip, there would be a very compelling reason to choose SB over IVB for overclockers.JSt0rm01 - Tuesday, May 8, 2012 - link
But I feel like the release schedule has slowed way way way down. We need amd to step back up to the plate. We need more competition. I have been waiting on the new xeon parts for what seems like forever.-------------
Also, after being a member of the anandtech forums for 10 years I was permanently banned by the moderators there because they wanted to censor a website (ffdt.info) that had conversation that was critical of their moderation. I find that the free flow of all information on the internet is critical. For a tech website such as this to limit the flow of information is offensive the core of these beliefs and its all because certain people in positions of illusory power deem that information detrimental to their positions.

To your first point, x86 development HAS slowed way down and the trend will continue. With consumer computer usage turning more to cell phones and tablets, the market for faster x86 parts can no longer sustain the billions of dollars of R&D necessary to advance x86 state of the art. Intel is probably in the process of reducing their x86 R&D budgets in anticipation of this.This will not change, even if AMD makes a comeback. I have predicted in the past that the fastest x86 part ever to be produced will be no faster than 50% faster than the current fastest Ivy Bridge. I stand by that prediction.
Sadly, the heady days of rapid advances in x86 tech are over, as anyone who witnessed the early/mid 2000's and can compare them to now will testify to.

Its unfortunate for power users. I will probably end up with a 2010 6-core mac pro to replace my aging 2006 macpro (please no anti-apple I use certain software and my industry is almost 100% apple I also have been building my own pcs since 1998) but what comes after that? I've already held this macpro for longer then I've had any computer. I guess what comes next? Will arm processors in 15 years be monsters of computational power?-------------
