EasyTune6 is Gigabyte's take on the monitoring and overclocking software within Windows. When you open the software, the Tuner tab opens by default. It offers three different “Quick Boost” options which are described in greater detail within the overclocking section of this review.

EasyTune6 does pretty much what you’d expect from this kind of software. It tells you everything about your CPU, memory, graphics card(s) as well as providing a hardware monitor and the ability to change your fan profiles.

EasyTune6 allows you to manually set fan profiles within Windows. The default is set at 27% when your CPU is at 20°c and 100% when it reaches 72°c. It increases as the temperature rises in order to try to keep the CPU temperature down. It’s simple really, if the CPU is still getting warmer with increased fan speeds, then the fan isn’t moving enough air so it speeds up more to bring the temperatures down. If all else fails and the CPU reaches 72°c or above, the fan will run at 100%.

When you select the advanced option, you can manually adjust the settings of the two fans that are controlled by the CPU temperature. Unfortunately, you cannot change the speed of the CPU fan and SYS_FAN2 individually - both are controlled by the CPU temperature. SYS_FAN1 and PWR both run at 100%, no matter what. There is no control over those.

You can overclock your system from within Windows. EasyTune6 allows you to change most of the required settings. You can alter the BCLK, DRAM frequency, multiplier and the system voltages.

    Use of plurals for a single entity derives from not knowing which part of that entity the speaker is talking about. It is very curious. I may be wrong but I cannot remember, "IBM have", "Apple have", "Asus have". They are all upstanding members of their trade and craft. But, while Gigabyte is good enough, there is something about it that prevents people from looking at it as a solid entity that deserves a singular reference. In fact, I would go as far as saying that the message is that the unpredictable collection known as Gigabyte has given us this, this time at this price. Gigabyte could as well have priced it $420. As if the pipeline is just cut off at random by a random part of that collection and a product shipped to the market. Not the case with Asus or IBM. Hence, IBM "has", Asus "has".

    Of course, with regards to the British the plural is a sign of respect. Remember, they are a monarchy, with hereditary parliament membership, and apparently very happy and proud of it. It is absurd to refer to a member of the house of lords in singular terms. Each is a well known clan. Oh, and well respected!!

    I'm glad someone brought this up. Anandtech editors should edit articles to be consistent.

    The problem is that American English has a different rule than European English. The American English rule is the correct one. A well-edited scientific site like ArsTechnica recognizes this and edits all of its articles (notice that I used the singular possessive pronoun "its" there) to that end. Anand himself does a nice job with this since he's an American.

    Some of the other American writers are being influenced by Wikipedia, British writers, and other sources of confusion. The fact is that number must agree throughout the entire sentence. Logically, the British rule can never accomplish this harmony of number because the corporate entity is always singular. Writers can easily avoid ambiguous constructs by making the subject more specific which helps convey meaning, eg., "Apple's engineers have" or "nVidia's marketing gurus are," etc.

    Grammar can be an observance of and more than, rules. Style may be approached. Cautiously.

    "I'm glad someone brought this up. Anandtech editors should edit articles to be consistent."

    I'm glad someone brought this up. Anandtech editors should edit articles for consistency.

    English writers have and are not considered a source of confusion with the English language any more than writers of other nationality's, Americans included.

    Corporations and other entities can be personified perfectly well.

    'Apple has pursued it's singular goal' is acceptable as the intention of one entity, further distinctions are made with relevant reference.

    'Jobs has a plan for apple"

    Two comments above

    'The right honorable' is considered the appropriate honorific (they rarely are), it is singular and they, depending on who you ask, are sometimes respected.

    British English is adequate until you reach then end of it, then you can use American English if you must. ;)

    I have literally no idea what you were trying to say there. Reading your post made me feel like I had been drugged.

    "The problem is that American English has a different rule than European English. The American English rule is the correct one. "

    Look buddy, American English is not correct. Americans cannot spell and if, like me, you have ever had to read a document drafted by an American lawyer, punctuation is not an American strong point but verbal diarrhoea is.

    I would say that the only correct form of English is what you call British English, but fact is that English is very flexible. As long as Anandtech are consistent that is fine.

    Anyway back to the board. Fan control. Do Gigabyte own shares in one of those companies who make separate fan controller? Because that is the only excuse for such a pitiful on board control
  • MadMinstrel - Wednesday, July 13, 2011 - link

    It's funny how you can determine with such certainty that one rule is correct and another is not. Language is not based in math, it is an arbitrary set of rules driven by speaker inertia. If both variants of the rule set are equivalent in functionality, neither can be considered correct or even superior. In "Gigabyte has/have released a new motherboard", "Gigabyte" could mean either "the Gigabyte corporation" or "the people at Gigabyte". I could argue that the singular variant is illogical because a corporation, an abstract entity, cannot perform any action other than perhaps come into existence. Or I could argue that the plural variant is wrong because fewer people use it. This, of course, would be pointless.

    nice board, but without speed control on the sys fans, it is less interesting than other options... also very few sata ports for a new product. Gyigabyte is really keeping it "safe and cheap".

    One of the great things about UEFI is the faster boot times. Does this hybrid BIOS allow the same? If it's merely a question of cosmetics, then the classic BIOS look would not bother me.

    How was the cpu temperature measured?
  • cyberguyz - Monday, July 11, 2011 - link

    ... and most motherboard manufacturers are guilty of this, is the fact that they stick the PCIe-1x slots directly below the PCIe-16x slot and leave the outdated PCI slots wide open down at the bottom of the board. It really burns me that these guys don't think of the fact that most new add-in cards are being produced to use in the more modern PCIe-1x and PCIe-4x slots. An example is that I have a PCIe sound card, a high speed network card and a raid controller. Because I also have an Asus GTX 570 Cu II video card (eats 3 slots), I can't use any more than two of these (If I don't mind losing 8x lanes to by x16 card and don't mind snuggling up the shortest one of these PCIe cards really close to the backside of that really HOT video card). Yet I have 2 ncie cool PCI slots sitting out there in the open airstream with no hot components anywhere near them. Video cards are challenging enough to cool without crowding cards within a couple millimeters of them.

    In order to use all my PCI devices I have to find one of the very few and more expensive motherboards that provide nothing but PCIe slots (No PCI bridge = more expensive - where is the logic in that?)

    Grrrr! I have no gripe in mobo makers including a couple PCI slots. There are users out there that will still use them for a few years to come yet. They just need to think that as we progress in technology that these older slots are being abandoned by users in favor of the more modern PCIe versions of their add in cards.
