To the firmware for its Z87X-UD4H, Gigabyte adds some of the features its chief competitor spent nearly an hour bragging about, including a Performance home page with the most frequently-used clock settings. For Gigabyte, this is simply an advancement of its already-popular M.I.T. "Frequency" main menu, and does not include voltage controls. We were able to reach a stable 4.7 GHz after setting voltage appropriately.
The CPU Core Features submenu grows longer with Haswell, and now requires a scroll-through.
Changing DRAM Timing Selectable within the Z87X-UD4H memory menu to Quick allows full control of both channels within its Timings submenu. Expert mode allows per-channel timings.
Individual settings include primary, secondary, and tertiary timings. These can each be altered without affecting the automatic mode of other timings.
Wholly bloat(ed) Batman! Four submenus within the Voltage main menu have as few as one setting. We reached 1.30 V under load at the Z87X-UD4H’s 1.28 V setting, and a volt meter showed that the board’s 1.625 V firmware setting produced our memory’s 1.65 V DIMM rating.
Could we see some MBs around the $130-$140 mark? They're the interesting ones IMO, and would toast most of these in terms of value.
OTOH, the launch coverage said that was at 1.2V, while this is 1.3V, so I guess a few hundred MHz extra is reasonable.
Lot more variation than on IB's review: http://media.bestofmicro.com/X/O/335580/original/image019.png
If you have one of the affected drives and can't be bothered to reconnect it when it goes offline, wait a couple weeks and buy a board from the new batch.
The differences between boards in today's review are overclocking, power consumption, and onboard features. None of those things will change with the new PCH batch, and firmware updates should improve both batches equally.
Can you guys please test 6 SSD in Raid 0 on these mobos ? this is the only Advantage of upgrading to a Haswell over ivy/sandy bridge.
