Fully Unlocked Flexibility and Freedom With its fully unlocked multiplier, the Intel Core i7-2600K processor allows full control over the processor core/turbo and DDR3 ratios as well as power and current limits for the best possible overclocking results. It also allows for processor graphics overclocking for improved 3D performance. Intel’s cutting-edge 32nm micro-architecture with 2nd gen Hi-K+ metal gate process delivers the 2nd generation Intel Core processors with higher performance at lower power, thus better overclocking capability. (Intel P67 Express Chipset required for core and memory overclocking, and Intel H67 Express Chipset required for graphics overclocking.)
Intel Turbo Boost Technology 2.0 More intelligent, energy-efficient, and dynamic than previous generation, Intel Turbo Boost Technology 2.0 gives you accelerating performance when you need it. It delivers an even greater automatic speed increase by allowing processor and graphics cores to run faster than the base operating frequency for demanding applications if the processor is operating below power, current, and temperature specification limits.
Intel Hyper-Threading Technology (HT Technology) Intel Hyper-Threading Technology delivers thread-level parallelism on each processor resulting in more efficient use of processor resources—higher processing throughput—and improved performance on the multi-threaded software of today and tomorrow.
Intel Smart Cache Intel Smart Cache Technology dynamically allocates the shared cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from faster, more efficient cache subsystem resulting in significantly reduced latency for frequently used data and improved performance.
Integrated DDR3 Memory Controller Integrated memory controller enables two channels of DDR3 1333 MHz memory, resulting in up to 21 GB/sec memory bandwidth. Plus the memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.
Built-in Visuals (with H Chipset) The visual features built into the 2nd generation Intel Core processor family deliver everything you need to enjoy a stunning and seamless visual experience. Intel Quick Sync Video and newly-added Intel Advanced Vector Extensions (AVX) make media processing incredibly fast. New built-in Intel HD Graphics delivers discrete 3D graphics performance without the needed cost and power of a discrete graphics card, and features Intel Clear Video Technology than enhances video playback, image quality, and color fidelity for a premium visual experience. What’s more, add another dimension to what you see on your PC with Intel InTRU 3D technology which supports stereoscopic 3D Blu-ray playback in full 1080p resolution over HDMI 1.4.

N/A 4/27/2013 6:46:06 AM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Great Processor Pros: FAST Unlocked runs quite cool Cons: NONE Other Thoughts: I bought this CPU for my Hackintosh build over a year ago. Since I bought it I've had it running at 4.2ghz, its cooled by a Hyper 212+ (idle 30c, load 65c). 0 Problems and this thing literally handles everything I throw at it. I do a lot of movie editing and encoding, this thing is a CHAMP. Did you find this review helpful? Thanks for the valuable feedback you provided!

John 4/16/2013 3:28:48 PM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5 Pros: I give this processor my highest recommendation. I bought it in February of 2011 and it has been running almost 24/7 ever since. Its performance still leaves nothing to be desired. Cons: I look forward to building myself a new computer every two years or so, but this processor has stubbornly failed to become even a little bit obsolete, so I'm relegated to upgrading hard drives and video cards for now. What a bummer. </sarcasm> Did you find this review helpful? Thanks for the valuable feedback you provided!
JordanAustin 4/5/2013 1:39:33 PM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Best Processor I've Ever Owned Pros: * Still working (2 yrs) * Stable 4.5ghz like nothing * Cold (with aftermarket cooling) 62C / 143F under load Cons: * None Other Thoughts: * I bought a 2600k and Asrock Extreme4 back in 5/2011. With experimenting I was able to overclock it to 4.5ghz at 1.385v. Idles at 35C, Load at 62C. To this day the overclock is still running solid. Used with Arctic Silver and Zalman 9700. 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
N/A 3/22/2013 8:29:15 PM Tech Level: 3/5 Ownership: 5/5 Verified Owner	Rating: 5/5i7-2600k Pros: It lasts, I've had it for over two years now, and it wasn't a DoA. I have not OC'd yet because so far there is no need to. 7.7 on the windows ratings without OC'ing. Very fast and reliable with 4 digital cores to tag on. Cons: Runs a little hot with my ZALMAN CNPS9500 AT 2 Ball CPU Cooling Fan/Heatsink Odd because I have a good case and fans Other Thoughts: Computer Specs: CoolerMaster HAF X (Case) ASUS VW246H (Monitor) CoolerMaster SilentPro Gold 1200W (Power Supply) EVGA nVidia GeForce GTX 680 FTW+ 4gb (Graphics Card) Intel 520 Series 240GB (SSD "Amazing") + Seagate 1TB (HD "Junk") ASUS Maximus IV Extreme-Z (Motherboard) Intel i7-2600k Sandy Bridge 3.4ghz Quad Core (Processor) Corsair Vengeance 16gb 1600 mhz (Memory) 200mm x4 red LED /CoolerMaster/, 140mm x1 red LED /XIGMATEK/ (Fans) Logitech G9x (Mouse) SteelSeries QCK+ Heavy (MousePad) SteelSeries Siberia V2 (Headset) /// Backup SteelSeries 7H (Headset) Cyborg V.5 (Keyboard) Did you find this review helpful?

tRu_FEAR 3/19/2013 6:34:37 AM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/54.9 GHz Awesome (read pros) Pros: Has everything a non-gamer and gamer alike would need. Integrated Graphics can run some less demanding games BF2 and such. Also with the right configuration can be used in tandem with a pci-e graphics card as a secondary display port(i.e. pci-e running 3monitor surround and integrated graphics running tv for media, performance monitoring; etc) Hyper Threading for all the video encoding and for games that support it. As well as virtually making this quad-core a eight-core. I have had this processor for 1 1/2 years now and its still going strong. I originally had a arctic cooling freezer 13 pro CPU cooler on it hard to say what the temps were since im doing this review about 1 year after I replaced that with a Corsair H100 now I run at 4.9 Ghz @ 45-50 degrees C. I can say before the H100 I would easily overheat and hit 80+degrees C almost instantly attempting to overclock above 4.2. Windows Performance Index still rates the processor at a 7.8 out of 7.9 Cons: Only con i can think of is that this processor still goes for $319 and the newer gen ivy-bridges arent much more if not the same price and give you a better integrated graphics if you into that. as well as pci 3.0 capabilities(with the proper hardware) Also they consume less power and are give better performance and lower overclocks. but i suggest doing some homework to see if that investment is really worth the boost and if you are actually going to be utilizing those extra "bells and whistles" Other Thoughts: Fast, Reliable, Still hangs with the best of them. team this up with a good liquid cooling system and you got yourself an amazing machine. If your looking to upgrade your CPU without buying the best of the best and spending more on an entire build this is the cpu for you. Dont skimp on the mobo(body)cpu(brain)psu(heart) of your pc and anything else goes. gpus get changed all the time and thats the only other thing you would want to invest in but only if your a gamer or graphic designer. 1 out of 1 people found this review helpful.

Steve 3/13/2013 8:47:51 PM Tech Level: 3/5 Ownership: 5/5	Rating: 5/51 Year Owner Pros: Amazing processor. I have yet to max it out and im a gamer. Does everything i ask of it, without showing any slowing down. Cons: None Other Thoughts: Although i didnt buy this off newegg myself. My friend who bought it did. But he ended up changing his mind about building a gaming computer so he sold this processor to me for 150.00. Well worth it. So thats why i descided to give it a review :) 0 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
arthur 2/28/2013 6:54:16 PM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Almost 2 years later the value has still held its place Pros: One of THE most efficient CPUs ever made. Throw anything at it and laugh away because this has workstation capability while still being the top contender in gaming. I overclocked this bad boy from 3.4ghz to 4.2 ghz on a Zallman 92mm aftermarket fan with great stability. I would push it farther but I'm happy enough as it is. At a price tag of $320 my sole intention was to future-proof myself for a minimum of 3 years. I'm almost at the 2 year anniversary and nothing has made me question that it won't make it to 2014 because by golly it sure will. Cons: Not really a con but should I have waited til Ivy Bridge? My answer to that question is no, at the time I would have had to wait another 9 months before I could buy my PC. The technology gap isn't nearly significent enough for me to have waited.
