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.

I think you are confusing bits per second vs. bytes per second. Do not be alarmed, that is the gimmick of Ethernet.10 mbps (megabits per second) = 1.25 MBps (megabytes per second)
100 mbps (megabits per second) = 12.5 MBps (megabytes per second)
1 gbps (gigabits per second) = 125 MBps (megabytes per second)
If you want 1 GBps, you will need an 8 gbps connector i.e. (10gbps nic)...and good luck with that.

theSeb's (and originally adrien's) point here is that the chart for LAN speeds erroneously list MBps instead of Mbps.HollyDOL - Wednesday, May 9, 2012 - link
Transfer speed is always measured in bps (bits per second).Latin prefixes for kilo-Mega-Giga etc. signify 10^3,10^6 etc. bits
Capacity volume is always measured in B (bytes).
Latin prefixes for kilo-Mega-Giga etc. signify 2^10, 2^20 etc. Bytes (ie. 1kB = 1024 Bytes) according to old school rules.
According to new customs kilo-Mega-Giga signify 10^3,10^6 etc. Bytes, prefixes kB, MB, GB, while alternate prefixes kiB,MiB,GiB signify 2^10,2^20... Bytes. Data storage capacity uses new style kB,MB,GB,TB for long years since it makes their drives look bigger, while on hardware and OS level you are much more likely to see units based on power of two since it is much more natural for binary computer.
Basically 10Mbps = 1.25MB/s is completely wrong... 10Mbps = 10,000,000bps = 1,250,000 B/s = 1.192 MB/s
1TB (new style or storage device manufacturers) = 931,32GiB

What is draw of power from GPUs?IanCutress - Tuesday, May 8, 2012 - link
The 7970s should Idle at approx 3W or less each.gorg_graggel - Tuesday, May 8, 2012 - link
the current asus lineup seems to have problems with memory configs that consist of 8GB dimms...their list of supported memory modules seems to be made for multiple boards...it contains configurations for e.g. 6x4gb for boards that have only 4 slots...so i guess it`s not only a problem with my board...
i got myself a sabertooth z77 and a pair of corsair 1600mhz 8gb dimms. no matter how conservative i set the timings the board won`t boot at 1600mhz and freeze after some time at 1333mhz (spd or xmp don`t work either). i can only get them stable at 1066mhz. a single dimm runs fine at the specified clocks and timings.
could you spare some time and test the boards with a 1600mhz config with 2 8gb dimms? or even with 4 of those? no underclocking of higher specced dimms, as there is a 2x8gb@1866mhz config in the list...
would be interesting to know if all those boards had problems with ivy brigde`s max specified dram clocks...
i guess it will be fixed in a future bios update, but maybe beeing pointed out by a respected site, they are gonna hurry it up a bit...i mean c`mon 1600mhz rams at 1066mhz? seriously...

so, i got myself another pair of 8gb dimms...g.skill ripjaws 1600mhz, cl10...
those worked from the get go...also not on ovl list...
the latest bios (1015) made the corsair dimms work better @1333mhz (no more freezing), but still no 1600 (for which they are specified)...
so if you plan to get 8gb 1600mhz dimms for your asus board, steer clear from corsair vengeance low profile dimms...at least until the bios has matured some more...

The $225 Asus V Pro has the Realtek ALC892 audio chipset while the $148 Asrock Extreme4 has the 898! Not everyone wants or can install a sound card so what are they thinking?GIGABYTE GA-Z77X-UD5H-WB Has wireless, 898 audio chip and a third PCI-E 3.0 slot for $219. That's a good reason to pay an extra $70 over the Asrock Extreme4 as I don't really care about auto-over-clocking.
Only Asrock at budget and Gigabyte at mid-end are in it to win it. Not enough high-end boards to tell who won there.
I am shocked by what Asus put on the table but I might be missing something here.

Gigabyte's third PCI-E 3.0 slot cannot work if CPU BCLK OC only 1MHz to 101MHz. It is buggy M/B. Don't buy it.blacksun1234 - Tuesday, May 8, 2012 - link
I mean GIGABYTE GA-Z77X-UD5H-WB . GA-Z77X-UD3H is Ok for 3rd PCI-E 2.0.
