Review: Great, reliable, stable OC CPU for the price - Purchased this new from desertcart back in September for my new build. Using a Corsair H115i AIO. I'm really impressed with the 5820k. It wasn't my first choice, had my eye on a 5930k atleast, but do to my budget and reviews online, i pulled the trigger on the 5820k. So glad I decided I went with this one. I have mine OCd to 4.3Ghz with no issues and usually hovers around 50c-60c during full load. Yea it only has 28 PCIe lanes...but Im running a Nvidia 1080FE's in SLI and it handles any game I can throw at it. This CPU is really a great all around processor for a good price. I highly recommend to anyone that cant decide on a LGA2011v3 CPU. Like I said it only has 28 lanes and it does very well with my SLI setup. If you are doing M.2 or PCIe storage setups along with SLI, I would recommend a 5930k or better with 40 lanes. However, if you only want 1 GPU and the M.2 or PCIe storage, the 5820k can handle it with no issues. 5820k @4.3Ghz/Asus X99AII mobo/32GB Crucial Billastix2400 RAM/ 2x 1080FE SLI/EVGA 1050watt PSU/ Thermaltake Core V51 case/ Samsung 850 SSS 250GB for boot/Seagate 2TB HDD. Review: Great all around CPU! - If you are looking to build or upgrade your computer, take at look at this CPU. It can do almost everything! I had an AMD FX8350 and decided I could no longer wait for AMD's Zen cpu to be released. I had to do thinking about getting this CPU and changing to the X99 platform as Intel recently released the Skylake series. I had to choose between Haswell (4790K or Xeon E3-1271 v3 ) and keeping my DDR3 ram; Haswell-E (5820K) and upgrading to DDR4 ram or (Skylake) 6700k and still needing to upgrade to DDR4. My PC is a daily driver that I also game on, some video encoding along with light photo and video editing. After looking at all the benchmarks and weighting the pro and cons I settled on the 5820k and could not be happier. I am able to overclock (settled on 4.3 @ 1.25 for stability and to keep heat down. I am still playing with this), which lessens the lead of single thread performance of the Skylake 6700k. I also like that I am getting 2 more cores that can speed up activities that can take advantage of more cores. Alot of the hitching I was having in games is reduced and gameplay feels smoother in general. The time to encode videos has really improved. This is a great all around CPU and can be the basis of a great machine! This might not be the CPU to get if you are mainly gaming, if you need more cores or the 40 PCIE lanes (as opposed to the 28 the 5820k offers), you are probably looking a the the 5930/5960 anyway. ## Features - Go to the next level of multi-core performance - Intel smart cache - Intel Quick Path interconnect - Integrated memory controller - Intel Hd Boost - Core I7-5820K PROC FC-LGA12A - Supported memory: DDR4-2133 - Turbo Boost Technology 2.0 - Unlocked Processor ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00MMLXIKY | | Best Sellers Rank | #1,333 in Computer CPU Processors | | Brand | Intel | | Built-In Media | Other | | Cache Memory Installed Size | 15 | | Customer Reviews | 4.7 4.7 out of 5 stars (658) | | Global Trade Identification Number | 00675901296304, 00735858285490, 00735858285506, 05032037065702 | | Item Weight | 0.3 Pounds | | Manufacturer | Intel | | Model Number | BX80648I75820K | | Platform | Windows | | Processor Brand | Intel | | Processor Core Count | 6 | | Processor Count | 6 | | Processor Number of Concurrent Threads | 12 | | Processor Series | Core i7 | | Processor Socket | LGA 12A | | Processor Speed | 3.3 GHz | | Secondary Cache | 15 | | UPC | 779184137368 735858285490 735858285506 675901296304 803983048232 | | Warranty Description | Limited warranty; 3 years warranty | | Wattage | 140 watts | ## Product Details - **Brand:** Intel - **CPU Manufacturer:** Intel - **CPU Model:** Core i7 - **CPU Socket:** LGA 12A - **CPU Speed:** 3.3 GHz ## Images ![BX80648I75820K Core i7-5820K Desktop Processor (6-Cores, 3.3GHz, 15MB Cache, Hyper-Threading Technology) - Image 1](https://m.media-amazon.com/images/I/91i7qFINxJL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Does it come with a cooler?** A: No it does not. I would highly recommend a very good closed water loop cooling system like a Corsair H110/105, Cooler Master Nepton 280L or something similar, especially if you plan on doing any overclocking or 24/7 type operation. **Q: does it have a graphics function built in?** A: The i7-5820K does not come with built-in graphics, nor do any of the Haswell-E parts. **Q: Does it come with heat sink and thermal paste?** A: No this cpu did not come with a heat sink. Any socket LGA2011 heat sink will work, but get a decent heat sink to keep temperatures in check. **Q: can this handle 2 GTX980 graphics cards ?** A: Yes. It could handle two of them. However you are limited to 28 pcie lanes. So they wouldn't both run at full 16x speed and keep in mind that not all motherboards have more than "one" 16x speed pcie slots. For instance, even on a board with 2 - 3 pcie slots rated at 16x, you are only going to run 16x full speed on the first card and maybe 8x on the second card. If the slot is rated at 8x the second card will only run at 8x. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great, reliable, stable OC CPU for the price *by D***L on December 14, 2016* Purchased this new from Amazon back in September for my new build.

Maybe if you were running dual+, high-end graphics cards, but this is going to do a lot that is thrown at it. Perfect price-to-value ratio currently. For cooling I went with the Cooler Master Hyper 212 EVO, works great for anyone looking for air cooling. Good benchmarks, and runs cool with my current cooling.

Cons: None so far concerning performance and heat The ONLY thing that I consider a con, is that you have to get DDR4, which is priced high since it's new. I consider DDR4 a blessing.
