Five Z87 Motherboards Under $220, Reviewed

Z87 Extreme6 Firmware

Though everything can potentially be configured manually, the easiest way to overclock your Haswell-based CPU from Extreme6's firmware is to pick the pre-defined clock that’s closest to your desired settings, and then make minor changes. Built-in configurations up to 4.8 GHz at 1.42 V were initially stable with our CPU, though thermal throttling forced us to seek lower values.

Starting with the "Turbo 4.4GHz" profile, I was thrilled to achieve 4.6 GHz through a simple multiplier increase. Then again, this was the first board I tested.

Our test memory’s DDR3-3000 XMP setting almost worked, but the Z87 Extreme6 firmware doesn’t appear to know the multiplier limits of Intel’s memory controller. The memory is supposed to operate at the DDR3-2933 ratio with a slightly elevated base clock, but I had to manually set its multiplier.

The Z87 Extreme6 also surprised us by adding 60 mV to our DRAM voltage setting, and then misreporting the actual voltage. Our volt meter revealed that 1.65 V actually occurs at the 1.59 V setting, and that the 1.59 V monitored value is simply inaccurate.

Primary, secondary, and tertiary timing controls are all available for full tuning, and each item can be separately changed from automatic to manual configuration.

    Who did you get the CPU from? Given the Haswell launch article said they were unlikely to be able to hit 4.5GHz+, is this a cherry-picked chip from Intel?
    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.

    Intel says it doesn't cherry-pick chips for reviewers...

    Thank you. I was looking forward for a review like this. I read some reviews and the o/c was varying from mobo to mobo lot. So if the same cpu was used, 4,3Ghz to 4,7Ghz is a lot of difference. Because if your cpu would o/c to 4,3Ghz most we would tell its a crap sample Haswell sucks on o/c etc etc, but if it was be able to clock to 4,7Ghz we would say its a nice sample.

    Yes, the CPU comes from Intel. Almost certainly it was cherry-picked. But this is why we didn't rely on these CPUs for our launch coverage--it makes a lot more sense to go to a source with hundreds of boxed processors on the bench to get a real sense for what Haswell will do in the wild. At least for this round-up, the variable changing is the motherboard. So, we derive as much meaning as possible with a review sample that hits 4.7 GHz on one board and 4.5 GHz on another.

    Yeah - but if people think that their chip is going to hit 4.7 on a good board, then find they can't get 4.5, they can be upset.

    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

    Isn't there a flaw in the Z87 technology regarding sleep mode? Was it mentioned in the article? I didn't see it.

    do these board suffer from the rumoured usb3 sleep issue? or are they the fixed B3 steppings ?

    Did you read the Haswell review? All current boards are affected, no future boards will be, there's nothing to update here, and the flaw is virtually meaningless.

    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.

    Hello,
    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.
