About this product

Product Information

Upgrade your computer system to a quad-core processor with the Intel Core i7-975 Extreme Edition. Featuring speeds of up to 3.33 GHz, the device lets you handle multiple programs and applications simultaneously without any slowdown. Achieve even higher speeds of 3.6 GHz by overclocking the CPU. With four separate cores and eight individual threads, the Intel Core i7-975 Extreme Edition will give you the ultimate multimedia experience on your home desktop computer. Multitask up to 25% faster even with the most demanding applications, so you can blaze through video editing jobs with ease and share your high-definition videos with the world. The Intel Core processor has also been carefully optimized to provide the powerful backbone for an awesome and immersive gaming experience. With advanced physics, artificial intelligence, and unparalleled graphics, this device achieves a solid benchmark performance.The Core i7-975 Extreme Edition features an integrated DDR3 memory controller that delivers higher memory bandwidth. It contains three memory channels running at a clock speed of 1066 MHz and a maximum bandwidth of 25.6 GB/sec. It also has an 8MB L2 cache to run multiple processor-heavy programs simultaneously. The cache is a small memory pool that can store important data on the CPU. Thanks to Intel's Smart Cache technology, this device allows all four cores to dynamically share access to this pool, reducing latency and improving bandwidth.The i7 family of processors has been designed from the ground up to take advantage of the most powerful desktop computers. In place of the old front-side bus design, Intel has created a new architecture called Quick Path Interconnect. QPI architecture creates multiple pairs of high-speed, point-to-point links both inside and outside of the microprocessor, so you get faster data transfer between the CPU and the integrated memory controller. The bus speed operates at 6.4 GT/s. Furthermore, Intel's cutting-edge hyper-threading technology makes the most efficient use of the processor's resources. With two threads per core, the processor delivers incredible, unmatched performance for highly-threaded software such as media players and games.The Core i7-975 includes many other features that will improve the performance of your CPU. Enhanced Intel SpeedStep allows the computer to dynamically adjust the processor's voltage and frequency to optimize the performance of the system. Intel Turbo Boost increases the processor's speed to give you a boost when you're below the thermal limit. Intel Wide Dynamic Execution delivers more instructions per clock cycle, improving the speed and efficiency of the CPU. Intel HD Boost dramatically improves the rate of high-definition video editing and encoding, so it encodes videos up to 79% faster. With Execute Disable Bit, it also prevents the proliferation of harmful software on your computer or network. In addition, the processor will automatically save power when it's idle. The processor has a Thermal Design Power (TDP) of 130w. That is the average power that the microprocessor dissipates when it's operating at its base frequency. With an LGA1366 socket, the microprocessor is compatible with motherboards based on the Intel X58 Express chipset.

The item was advertised as new but it wasn't, and it wasn't the item in the photo. It arrived sealed and with no shipping damage. The parts that were broken off the PCB did not exist in the packaging, and could not have fallen out as they were far too large. Upon further inspection, there were also wear marks on every single connection point to indicate the item was not exactly new, either. Possibly tested, or installed once. I am currently unable to contact the seller directly.

    After months of testing and letting it sit only to test again. CPU was never faulty, it was the motherboard I installed it in. Has been working for about 6 months without issue. CPU Installed in an EVGA x58 FTW3 Motherboard with Corsair H100i V2 120 mm liquid cooler.

  • Top critical review

    Old, but still worth playing with.

    This is s great 10 year old processer, not real valuable but works good.

  • Fast. Extremely overclockable (on air cooling, liquid cooling provides extra overclockability). Great choice.

    Was able to overclock this identical processor over 1 GHz. Fast. Extremely easy to set up. Gives your rig a great boost in CPU horsepower. Very reliable. Absolutely no issues - 24+ hour burn-in period after overclocking. Still using the same processor for over a year, after upgrading from a 920. Incredible jump in performance. At one point, this processor was selling (NIB, sealed) for ~$1200. To get it in NEW condition for less than 400 is a steal. Especially if you don't want to build a new rig from scratch (PS, MB, CPU, RAM, SSD, etc.)! Highly recommended.

  • the old mantra holds no longer

    They used to say a computers life time was 3-4 years. I slapped this into my SEVEN year old motherboard as an upgrade to the 2.6GHTz CPU it had. New machine.

  • Intel i7 975 Extreme processor

    Great processor . Blazing fast runs cool. Comes with a huge heat sink and fan which runs between 42 degrees C to 52 Degrees C in my system. The i7 975 Performs as advertised. Excellent product for any serious gamer. Speed is teriffic, runs at 3.33 GHz. No need to over clock this baby. I am very please that I selected this i7 processor for the heart of my new system. Running on an Asus Rampage II extreme mother board with 2 EVGA GTX 295 CO-OP graphic cards in SLI mode with 12 GB of Corsair Dominator memory (6x2)in a Corsair Obsidian 800 D case. Powered by a Corsair Hx 850 modular PSU. System is a screamer. The i7 975 Processor handle the system well with no problems.
