MSI Z77A-GD65 - In The Box
The MSI Z77A-GD65 is currently available for $190, just north of the Gigabyte board. With this in mind, we also get a few more extras in the box than the Gigabyte:
IO Shield
Driver CD
User Manual
Certification of Military Class testing (FWIW)
Four SATA cables
Flexi-SLI bridge
M-Connectors (to help front panel connections)
V-Check cables (to help with voltage read points)
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.
Similarly to the ASUS board in this review, the MSI has minor variations in the CPU voltage. Worthy of note though is the lower VCore used by the MSI board compared to the other boards in this review while at load, suggesting more aggressive LLC settings.
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.
Overclocking options on the MSI Z77A-GD65 are relatively straightforward. With the OC Genie button on board, give it a press and it lights up, causing the next boot to initialize a series of predefined settings for an overclock. Manual overclocks can be done by the Click BIOS software in the operating system, or by adjusting the BIOS directly.
Automatic Overclocking: After pressing the OC Genie button, it essentially seemed to enable the Enhanced Turbo option in the BIOS. The system booted without issue, and I was greeted with a 39x multiplier under all loads, showing 1.080 volts and 65ºC with PovRay. This is a rather disappointing automatic overclock. This is also indicative of issues relating to one button overclocks - the manufacturer is supplying a series of presets that has to work on every processor out of the factory. It is perhaps time that MSI introduces their own stress-testing overclock into the mix to get a better result.
Manual Overclock: Given the previous overclocking results achieved, with the MSI board we jumped straight in with 1.2 volts, with PLL Overvoltage enabled just for good measure. At this voltage, 46x multiplier was the highest multiplier stable, giving 82ºC with PovRay and showing 1.184 volts at load. In order to get the 47x multiplier to work, it required 1.250 volts on the CPU, although this gave 90ºC during PovRay and 1.240 volts at load.

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.
