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.

Article: "With a lot more controllers to initialise on board, the ASUS P8Z77-V Pro requires at default 20.47 seconds to reach the windows loading screen. By disabling controllers that aren't used, a time more like the ASRock could be achieved."Did you actually test this?
And a suggestion: please test Intel DZ77BH-55K motherboard. It is the only board besides MSI to use the better ACL898 and Intel LAN chip but without other useless bulk (like secondary LAN etc). It seems to have superior BIOS to many others.

Hi Paapaa125,I should have an Intel Z77 board inbound to test. I have about 5 others to test as well, and some ITX. Currently reviewing boards in my spare time, so please bear with me as I get through them all! :)

Great to hear that! And no need to rush, I can wait :) I hope you test these things:Boot time. Fan control settings. Power consumption. Lan speed/CPU util. Audio quality. And check if the Turbo Boost settings actually are identical. Otherwise the benchmark results are unbiased.
I'm actually more interested in other features than pure computational speed and benchmark scores. The differences are usually insignificant, but the differences in other areas might be big.

Somebody further down the thread posted a message that they configured their Asus 'board to POST much quicker than above.I second request for Intel board reviews! I am particularly interested in the DZ77GA70K as well as the 55K mentioned by Paapaa125. I've been hearing good things about the GA70K but I'm hesitant to commit without finding out about POST times and I'd also like to see if performance is the same between the 55K and 70K.

Can you give us realistic power supply measurements? I am interested in building a fairly fast system that is pretty much always on. So the idle power needs to be as low as possible. I would use a smaller power supply that is at least 85% efficient @ 50 Watts. And no video card. With just one SSD and one optical drive. My best napkin-guess would be an idle power of 40-45 watts.Silenus - Tuesday, May 8, 2012 - link
That's a fair guess for idle. The problem you will have is that ideally you will want a high efficiency supply that at idle is at least 20% loaded. For you 40-45 idle that means you would need a supply probably not more than 200 watts. It is hard to find a 80+ supply at those lower powers. You might consider a small form factor supply. This is just about fits your requirement:http://www.neweggbusiness.com/Product/Product.aspx...

That might be a good choice. I wonder if I would still be able to hit 4.3GHz with that supply. I would definitely keep it at stock volts.haakon_k - Tuesday, May 8, 2012 - link
..or try the 80+ gold alternative from seasonic, if you can find a shop that sells it, 300 or 350W - optionally modular.http://www.seasonic.com/product/pc_tfx.jsp
Unfortunately without any PCIe 6 pin power connector, if you so should get tempted...

Well that review went as expected. MSI underperformed, Asus was needlessly expensive, Gigabyte had memory issues, and Asrock OC'd with lower voltages. That;s mirrored my experiences in the past few years.goldie.lin - Tuesday, May 8, 2012 - link
Thanks for the nice benchmarks, USB, SATA, LAN, Power Consumption, ...Especially, I appreciate the "DPC Latency" and "Boot Times" tests.
It very useful and practical!!!
Keep working, AnandTech.
