Six Sub-£160 Z77 Motherboards, Benchmarked And Reviewed

P8Z77-V Pro Firmware

The P8Z77-V Pro pushed our Core i7-3770K to 4.77 GHz at 1.30 V using a 101.4 MHz base clock and 47x core multiplier. We began our overclock at A.I. Tuner’s X.M.P. overclocking mode, rather than using purely manual or Asus-defined overclock settings.

Shown at DDR3-2703, the P8Z77-V Pro pushed a stable DDR3-2715 from G.Skill’s DDR3-2666 when a lower CPU multiplier was used.

Red warnings tell us that 1.30 V core and 1.20 V System Agent voltage levels are higher than suggested for Ivy Bridge, though some of our engineering friends advise otherwise. We asked many questions before choosing these settings, but only time can prove the adequacy of this advice.

Primary, secondary, and tertiary timings are all found within Ai Tweaker’s DRAM Timing Control submenu.

The CPU Power Management menu also provides the actual multiplier control for fixed mode, along with several current limits. Asus says that Automatic power settings are more than adequate for all but the most aggressive overclockers, and we never encountered a power reset or lock-up by using these.

Load-line calibration could be the most important feature of Asus’ Digi+ Power Control submenu. We were pleasantly surprised to find that Auto settings kept our CPU core voltage stable under various load conditions.

    Great review! At the end of day, it comes down to brand loyalty.
  • do you mean nvidia and intel gets news during weekends not only news but featured articles?
  • yougotjaked
    There's a typo on the last page. It says X77H2-A2X instead of Z77H2-A2X :P It's on the second to last paragraph...

    I am surprised that you guys did not include the Asus z77-V

    why not with Pci-e 3.0?
  • confish21
    Nice article thank you!

    One thing i was looking for was the part about asrock not having true "digital" PWM and going with an analog PWM. Does this really matter?

    TekN9NeGreat review! At the end of day, it comes down to brand loyalty.
    I don't think the article stated anything like that. It comes down to the features you want and the cards you plan to use. In the MSI vs ASRock debate, it's x8-x4-x4 with all three slots in PCIe 3.0 mode, or x8-x8-x4 with x4 in PCIe 2.0 mode, and you're definitely wiser to pick between them based on WHAT you plan to use in the third slot.

    It's Monday here, and editorial has very little contact with news.

    Tom's Hardware didn't "include" anything in the review. A couple boards were excluded based on price, and everything else was let in. The P8Z77-V Pro was the cheapest board Asus sent.
    rickrentswhy not with Pci-e 3.0?
    Editor had no PCIe 3.0 cards. And the reason he didn't get one yet is because it didn't matter. The only thing that really mattered in a single-GPU MOTHERBOARD comparison was to use the same card on all platforms.

    Some digital voltage regulators have been garbage, take a look at a few of the older reviews to see this. Very few have been very good. And many more analog voltage regulators have been garbage, while many more analog voltage regulators have been very good. Quality of execution is more important than the underlying technology.

    UD3H seems to be an excellent value board.
  • HMSvictory
    would it be possible to review the asus z77 and gigabyte ud5h in a future review.
  • tacoslave
    this review needs crossfire/sli results
  • AlexIsAlex
    Still no boot/post time comparison? With all performance scores being almost identical, I would have thought this could be a useful differentiator.
  • sosofm
    Is good a test with PCIE 3.0 video card to see if is a real benefit compare to PCIE 2.0.
  • valuial
    z77 sabertooth wanted !

    Thanks Thomas another Great Article! Don't like what I see, but I digress.

    Something's gotta be pooched with the ASUS P8Z77-V Pro BIOS (UEFI) -- hopefully. In the past the ASUS Pro line has been the meat & potatoes for my recommendations, and this is not the only review with similar performance numbers.

    Voltages, I am going to have a hard time recommending a vCore >1.2Xv, VCCSA and CPU VTT of 1.20v on the IB. I still need to see otherwise. From what I've seen the IB is more 'girlish' with voltages than the SB or SB-E, and there's little point having the fans spinning 'through' the case and creating high dBA with a high vCore. RAM (voltage), it goes back to my feelings that 1.50v DIMM was a bunch of Urban Myths especially since the SB-E and seemingly the IB can handle 1.65v DIMM RAM.

    Yeah, I noticed the XMP tried to set 1.25v VCCSA, or at least the set is encoded that way. Further, I don't wan to debate the OC until I get my hands on an IB, it should be any day now.

    Further, either the Engineers were dead wrong on the SB (1.50) or IB (1.65) they're wrong in both instances. I 'get' ultra fast kits (today) >DDR3-2133 e.g. DDR-2400 or faster are 1.65v kits, but only a few months ago IF 'I' recommended SB + 1.65v I'd have 20+ negative comments in the Forum. Seems counter intuitive step in DRAM voltage.

    Also, I am assuming you're testing the IB ES and I wonder how much of an impact that has in that the CPUID are geared towards the Retail. I remember all of the E5 (ES) problems and drops in performance compared to the Retail sisters.

    OC observation only, you seemed 'wimpish' with the SB-E compared to the IB - interesting?!

    i don't understand why the mobo don't have all sata6 and usb 3.0? i mean they're backwards compatible. why even include the old stuff? why not have 8 sata 6 and 8 usb 3.0 with 0 sata 3 and 0 usb 3.0? :?

    Good review, I read a similar review before i decided for MSI Z77A-GD65.

    A chose this board as it has a better Audio Chipset then the Competitors. This board comes with ALC898, while the other ones come with ALC892. Apparently ALC898 is far better than ALC892.

    So far i am quite happy with the board.

    Just 1 note, if overclocking do not disable "Power technologies", it will prevent overclocking. If i disabled the power saving features 1 by 1 i had no problems.
  • xtreme5
    like it good review!
  • Pezcore27
    Just curious as to what made you pick the GA-Z77X-UD3H for $160 over the GA-Z77X-UD5H for $189? Is there not that much difference between the 2 boards?

    Fun mobo review as always!
    I have always loved ECS for cheap 'value' builds (in fact I am using a 6 year old ECS board in a little htpc I am throwing together, it doesn't do much, but it has never let me down either), it is wierd seeing them in the 'high end' market like this, and (unlike previous boards they have produced) it looks stunning!
    The first time I saw the gold on black look was with my ex3 gen3 board, which looked odd in pictures, but great in real life, and this new ECS board looks absolutely gorgeous in pics, so I am sure it looks great in real life as well.

    Still, at the end of the day I am not sure that I would go for ECS on a high end build, but it is good to see that they are getting somewhere.

    Also, it is good to see that ASRock is still doing OK now that they are no longer under the ASUS umbrella.

    As for the review: Why even do the program benchmarks? We all know that the mobo is merely for the feature set, parts cooling, and power management quality for OCing (and truth be told aesthetics as well), and has next to no bearing on how fast things get processed at any specific frequency. All that I personally care about is the feature set, OC ability, and subjective ease of use for the UEFI and keeping it updated, vs the overall cost of the board.

    Blame intel for that issue. The intel chipsets only support two 6gb sata ports, so motherboard manufactures have to install add in chips to get more and that drives up the cost.

    Is there any reason I shouldn't pop an i7 2600k into one of these motherboards? I have no current gaming machine, and as such am not upgrading from any relevant platform.
  • shingudaze
    The only ECS Z77H2-A2X I can find is the regular one, not the golden, which seems to come in at around $220. I can't find built-in wifi on either of them, and the regular one doesn't state SLI ready.

    It's hard to figure out if the golden one is worth the $55 price premium instead of just going for the ASUS board.

    I'm not really satisfied with the z77 features. I was hoping they'd do away with all the gen 2 stuff and go all gen 3 i.e. no USB 2, PCIe 2, sata 2 etc. and go all gen 3. Why not since they're backwards compatible?

    Will there be a z78 chipset for Ivy Bridge? Otherwise, there will be zero upgrade options for the Ivy bridge. Especially since the z87 chipset supposedly will be for Haswell and the 1150 socket. I'd wait for Haswell but, my work computer I need to replace is from 2004 and I don't think it will make it another year.
