Six $220-280 Z77 Express-Based Motherboards, Reviewed

GA-Z77X-UP5 TH Firmware

A few easy settings help the Z77X-UP5 TH push a stable 4.69 GHz from our Ivy Bridge-based CPU. We got there using a 102 MHz base clock, 46x multiplier, and a 1.25 V target core voltage.

The Z77X-UP5 TH gets close to achieving DDR3-2800 data rates with our G.Skill DDR3-2666 samples. Choosing Quick tuning let you configure both channels simultaneously, while Expert mode allows per-channel settings.

Primary, secondary, and tertiary timings are adjustable, and individual settings can be left to the motherboard’s Auto adjustment. Changing the memory multiplier allows the board to deviate from SPD or XMP values, so we locked-in our memory’s 11-13-13-35 rating during our overclocking tests.

Keeping our CPU close to its 1.25 V target under both light and heavy loads required us to set Vcore Loadline Calibration to Turbo with a 1.24 V baseline CPU core. The memory similarly required a 1.625 V setting to produce a meter-checked 1.65 V at the DIMM slots.

    As u have reviewed SIX (6) motherboards, the article's title should be:

    No SATA and USB tests ? data transfer speed differences will typically be noticable in everyday usage.
    Also, the time taken to show the windows loading screen/ BIOS page..

  • admit it.
    you really liked the black/grey dimms and PCI slots of the gigabyte better than the blue/black of the MSI!

    robertaAs u have reviewed SIX (6) motherboards, the article's title should be:"Six $220-280 Z77 Express-Based Motherboards, Reviewed"Let's see what the article says:
    The one motherboard in today’s line-up with a 48-lane PCIe 3.0 bridge is ECS’ Golden Z77H2-AX. Unfortunately, this platform climbed $40 beyond the budget limit of today’s round-up in the time we've been reviewing it. We're tired of seeing board vendors playing pricing games based on our review schedule (this isn't the first time we're seeing a curiously-timed price move). So, since we put the work in to review ECS' submission, we're including our already-gathered data and simply withholding the board from any award candidacy.
    mayankleoboy1No SATA and USB tests ? data transfer speed differences will typically be noticable in everyday usage.Also, the time taken to show the windows loading screen/ BIOS page..Would have covered windows load time except that it wasn't markedly different. That is, after disabling empty SATA controllers. If you count the time that it takes to get the "No Device Found" error on boards that have extra SATA controllers, you're penalizing a board for having more features.

    Andrew Ku tests drive controllers. I'm trying to get him to "write the book" on controller performance, since dozens of boards use only a few different controllers. As for testing things like Z77 controller performance on board A vs Z77 controller performance on board B, it's a waste of time unless something is broken. So the article looked for "broken stuff". See the red bar on the first chart:
    http://www.tomshardware.com/reviews/z77x-up5-th-z77a-gd80-z77-oc-formula,3305-22.html
    With nothing broken, there's no excuse to test the Z77 controller six times. Back to me begging Andrew Ku for a comprehensive comparison of every SATA controller currently available on mainstream-brand enthusiast boards.

    Arghh! Why the hell are you overclocking the base clock on Z77!! That will most likely cause permanent damage to your CPU.

  • You left out a key aspect for overclockers which is vcore offset.
    This allows ocer's to achieve higher overclocks while still retaining the power saving functions, instead of being forced to either reduce the overclock, or be forced to run high voltage 24/7.
    MSI doesn't have this key feature.

    I would think that the Sabertooth's five year warranty merits at least a mention in any value conclusion.

    I'll just stick with sandy bridge. Doesn't seem like I'm losing much at all.

    Overclocking the BLCK is very unlikely to cause any damage, it's just likely to not give much of a stable overclock.

    jtt283I would think that the Sabertooth's five year warranty merits at least a mention in any value conclusion.I actually missed that, having checked the lesser brands just to make sure those still had their three year warranty. Will add it.
