The board has many good features: HDMI and DisplayPort video outputs, HD optical and analogue audio, and a reasonable set of USB 3.0 and USB 2.0 ports, along with three USB 2.0 headers and one USB 3.0 header, each of which should support two ports. The board supports up to 32GB of memory, has four 6GBs SATA ports (two driven by the Z77 chipset and two by a Marvel chip) and three 3GBs SATA ports. It supports front and back fans, and the latest GUI BIOs. It also supports over-clocking, although I have not implemented that on my system.
The Z77 chipset also supports the Intel RapidStore technology, which led to my first set of problems. I now have this running successfully with a single 2TB HDD and a 64GB SSD in a single array, with the 64GB SSD designated as the swap drive that accelerates the HDD. (Note: to use RapidStore, both the accelerated HDD and the SSD must be connected to ports controlled by the Z77 chip; you can't use the Marvel ports for this purpose.) I have a second 2TB internal drive that I use for backups. This is all working fine at present, and the SSD cache really does speed up the system. However, this is not quite the configuration I'd originally planned.
My original intention was to install the two 2TB drives as a RAID1 array (which the system sees as a single drive, with all writes mirrored on both HDDs), with the entire array accelerated via the 64GB SSD.Read more ›
The front-panel USB 3.0 headers simply do not work on any of this revision of this board. It's not just that my particular board had a problem, this is acknowledged to affect the entire inventory of this motherboard on the market. Yet they have no plans to fix it as it cannot be addressed through BIOS updates. Classy.
Next (and this is really the big one): they obviously did very little memory compatibility testing with this board relative to other manufacturers. Several of us bought these motherboards at the same time as they were on sale, and we have ALL had problems finding memory kits that will work reliably at the speeds advertised. A set of Corsair 2x8 DIMMs I purchased that test out just fine on other motherboards I tried them on will cause this system to not boot when present. A pair of Kingston DIMMs were verifiably damaged following a routine BIOS update. They worked perfectly fine until the BIOS was updated, now the system won't POST when they are present and they fail integrity tests that they passed before. I am now on my third set of system RAM in as many months using this motherboard, and my front panel USB 3.0 ports still don't work. I just wound up buying a USB hub from Amazon to replace that functionality. Intel support was of little help.
So yeah, this board has cost me over $500 just to keep it working properly, and it's still basically brand new. I will never, EVER buy another Intel Desktop board again. The Intel Desktop board line are no longer Intel products, they are Foxconn products, and rather shabby ones at that. Beware!
1. One heck of a time getting it to accept all four sticks of RAM. Took a long time and a lot of troubleshooting to validate there was nothing wrong with the RAM. Finally, for some reason, the board accepted all RAM and no more issues there.
2. Card reader connected via USB 3.0 not consistently recognized. I had to unplug and plug back in the card reader for the computer to see it. Would work fine, until restart. Then would have to go through the process all over again.
3. Board would not recognize a TV tuner card in any of the three PCIe slots. This was a good card that I pulled out of one computer and stuck in this board. No dice.
P.S.: I'm using default BIOS version (Version 0057) and default BIOS configuration. The only thing is when you install the Drivers DVD on Windows, I recommend you to only check "Drivers" and uncheck "Applications" category. The applications are mostly bloatware and are not needed for this motherboard to work. Then you must update "USB 3.0: Intel USB 3.0 Driver" for this motherboard downloaded from Intel website (I'm using version USB3_Win7_18.104.22.168_PV.exe). Without this updated driver, I couldn't use my external USB 3.0 hard disk if I plugged it into USB 3.0 port, but it's still working if I plugged it into USB 2.0 port. After the driver is updated, I can plug my external hard disk into USB 3.0 port and enjoy the increased speed.
