Farewell to overclock Intel Haswell microprocessors “non-K Series”

The new microprocessors Core fourth generation “Haswell-DT” for desktop socket LGA 1150, contrary to its successful previous generations (Ivy Bridge, Sandy Bridge and Nehalem) have received mixed critical on one hand many praise its the greatest its IGP graphics performance, but many criticize its higher temperature , irregular consumption and performance compared to its predecessor “Ivy Bridge-DT”.

A high staff to overcome

Perhaps the criticism is exaggerated and emotional further, given the good product that microprocessors were second-generation “Sandy Bridge”, and to a lesser extent third-generation Core “Ivy Bridge-DT”, and so many pinned their hopes which provide a considerable increase in performance, such as that offered in Sandy Bridge time over its predecessor Nehalem (Core first generation).

Although fourth-generation Core microprocessors “Haswell-DT” do not represent significant jump performance expected of a Tock (a major change in the micro-architecture while Tick indicates an improvement to the manufacturing process and minor changes to the micro-architecture), its overall performance is slightly greater than Ivy Bridge, becoming a worthy successor.

Perhaps you require a new socket (LGA 1150) is the main reason that many users possessing Core based computers second and third generation, not see with good eyes to these new microprocessors.

Haswell is a very good choice for users looking for a new team to replace his old team-based first-generation Core or any contemporary or earlier socket which is already discontinued, as well as for users who first acquire a team, which will be quite pleased and satisfied with all aspects of performance, and the new socket promises future updates without having to change the motherboard.

Haswell and overclockers

Not to mention that the best overclockers in the world have thoroughly squeeze every drop of performance that they can get the new Core i7-4770K microprocessors and Core i5-4670K, both the only microprocessors with unlocked multiplier and paths capabilities designed to the overclcok , this family of products.

Although Core i7-4770K and Core i5-4670K will steal the attention of overclockers, many casual overclockers kept hoping that even a few of the new features targeted to Haswell, were also available for other microprocessors Core / “Haswell-DT” non-K Series (cheaper), but unfortunately like many imagined it will not.

The Tech Report The claim to have tried unsuccessfully to overclock Haswell microprocessors various non-K Series, impossible task given that in the BIOS Setup options are not active to alter the Turbo multiplier (this could be done in non-CPU Core i7/i5 K Series LGA 1155 socket for small overclocks of up to 400MHz frequency above series).

When contacting Intel, this confirmed that these options are unique to the K Series microprocessors, and are not available in other models, since they are geared to businesses and consumers, market segments do not overclock their computers.

Some concessions

Although the Core i7-4770K microprocessors and Core i5-4670K are more expensive than CPU Core i7-4770 and Core i5-4670, given its overclocking capabilities; also have to mention that do not have the same functionality as the latter two given lacking support features like:

  • Trusted Execution Technology (protected execution environment applications).
  • TSX-NI (instructions to improve performance + multi-threaded hardware Transactional Memory Lock Elision +).
  • vPro (security, remote monitoring and management hardware).
  • VT-d (Virtualization of devices).

Of these TSX-NI is definitely an unreasonable loss of functionality in a product more expensive.


I must confess that I was one of the users who thought the overclock would return to low cost microprocessors as Core i3, Pentium and Celeron, which in times of first-generation Core “Nehalem” and earlier, could be overclocked to the point of rivaling with higher priced CPUs and range. But just those times will not return, at least not on the Intel platform.

The percentage of users who overclock their computers is considerably small compared with those who care about such matters, and just go on and enjoy their equipment, so we thought that this decision does not affect Intel almost nothing to both common users overclockers and enthusiasts.

We emphasize that fourth generation Core Haswell is an excellent product, but it’s always good to know all the pros and cons of the products before purchasing.

Well, times have changed Farewell to different overclock the K Series models!
