Update: 4/17/16: One thing I did notice with this CPU was that, at first, it was a bit unstable and ran a bit warm. I noted the first time it booted up a slight freeze then reboot and then Windows came up. The first set up was this way and then I started having freezes, lockups, and unannounced reboots running at 4.3 gigs. It seemed my first impressions were a bit high. I did a reset of the heat sink compound and tried again. Same thing at 4.3 gig. After placing my old i5 3.2 gig back in for a check and it running just fine, I decided to try once again. I removed the i5 and put in the i7. This time I cleared the BIOS as I had run into having old BIOS values mess me up at times. I also added a 120mm fan to the case's left side to set up a bit more air flow thru the case. I reseated my sound card and graphics card, and I made sure all cables were tight. This time when I booted up, the system did not hang but booted to the screen informing me a BIOS clear at been done. It was smooth and there wasn't a hang to it. I went into the BIOS and disabled the on board sound and that's it, I left everything else like it was and booted into Windows 10 Pro. Windows booted up without a problem and loaded fine. I cranked up the Intel Extreme Tuning Ulit, and checked things out. Turned out I was again running at 4.2 gig. The system seemed OK, but was some of the readings looked a bit off to me, so I decided to try a test and sure enough the system seemed to be a little shaky to me. I decided on another test before I ran any stress tests. I set the system at 4 gigs solid and observed the readings. Things seemed to setting down and the temps seemed to stabilize around 35 to 40c. Not as low as hoped but in range. Since I hadn't planned on an overclock anyway, this would be OK IF they didn't get much higher. I then ran 10 minutes worth of CPU stress and memory tests after a 5 minute benchmarking in Intel's uitil., and then a 10 minute stress test under OCCP and the system sailed thru them all with the temps never getting above 83c but just spiking to it and no locking up, freezing or reboots. I've noted it seems to run around 35-40c when idling and around 70-76c under load. The main thing now is it seems very stable at 4 gigs for me and that's what I wanted even if it took me a little while to get there.
Update: 7/18/16: OK, so here's the finally setup I had to run with. First, turned Turbo-boost OFF in BIOS. Second, ran Intel Extreme Tuning Tool and set CPU core voltage on this system at 1.1005 volts, with Manual static setting only as that was the setting that got me the most stable running. (No Adaptive as, on my system, this causes lock ups and reboots when sudden voltage spikes up or down hit the CPU.) In this set up, the system is very stable, runs cool (Around 35-40c idle and 50-60c under load) and allows me to run my games and any thing else without any problems at all. The only problem that I run into every once in awhile is when somehow the static setting gets switched back to the adaptive set up and I don't spot it in time, I'll get the total system lock up and need to reboot by the power button on the system, otherwise no problems and system runs very solid without problems. (I've play one game 12 to 24 hours without a problem with the static setup.) (Think that Intel should allow the user to "set" the most stable profile ae the "default" profile for their system but they don't.) I maybe should have got the "locked" 4790 but I wanted the 4 gigs running speed and not 3.6. Still think it's a really good buy.
My intent was to utilize the on chip video graphics to do this. 4k/UHD display standards are still emerging right now, so if you are planning to do the same do some research in advance. I also wanted to use a 40 inch TV as my monitor to save a few bucks and get up to the size I wanted to use (40"). I don't need 40" of monitor, but with 4k/UHD pixel density and a screen that large, I can place my work windows in a position that does not induce fatigue after a long days work and have additional windows open around it with less used tools open and ready to go.
If you are pursuing the same, I will make some notes you can use to get boot strapped into this little conquest.
First, UHD and 4k are actually not the same resolution. This is lost on some TV related web sites and advertising. 4k resolution is 4096 x 2160. UHD is 3840 x 2160. UHD is what TVs and UHD content will support. UHD has 4x the pixels resolution of 1080i. So to put some of this in perspective, a 40" UHD TV has the equivalent of 4 20" HD (1080i) screens in pixels. And the pixel density of a 20" HD monitor will be the same as 40" UHD monitor.
The only interfaces that support full 4k/USD resolutions right now are Displayport and HDMI. The UHD TV's available right now don't support Displayport. I purposely bought a mother board that supports Displayport to keep my options open going forward.
You are going to need to find a TV capable of rendering the pixels without trying to enhance them for TV and Movie viewing. The Samsung I purchased supports "just render"/gaming mode if you learn about its odd setting requirements. LG has a few that support this mode and there are a couple of Chinese manufacturers that do as well (Seiki and TLS).
All of them overwhelmingly have HDMI 1.4 ports on them. They don't include this spec on spec sheets unless they actually support 2.0. Then they will brag about it as a feature. The notable difference between these two specs is the frame refresh rate. 1.4 supports UHD up to 30 fps, 2.0 supports UHD up to 60 fps.
Motherboard manufacturers are the same on this front and I cannot find any that claim to support HDMI 2.0. They are at least more transparent about the resolutions and fps rates they support with onboard interfaces for HDMI so a little less hunting to confirm they are unable to support 2.0.
The Displayport option supports @60 fps at 3840 x 2160 (UHD). So that is an option going forward whenever converters for HDMI are released that support HDMI 2.0. To do that I will still need to upgrade the TV.
I use this computer for work related tasks so I don't have to have 60 fps. I settled for a Samsung TV with hdmi 1.4 ports knowing I would be limited. This particular model uses a proprietary Samsung port that allows for upgrades after purchase to latest features and capabilities in an external box. Thats fine, and whenever Samsung offers this option with HDMI 2.0 I will purchase it if I think I really need it.
The on chip display is doing a very good job @30 fps. I am actually surprised by that given that it is still considered inferior to most reasonable pci video cards. I left room for a pci video card if I need to use one at some point. Right now I don't.
If you are using Linux with Xserver/Xwindows like I am, the Xserver will auto select the first resolution the chipset driver lists that is compatible with the resolutions the hdmi port reports. On my TV the hdmi does not list options to the OS. So Xserver picks the very first resolution the driver for the on chip graphics lists and that is 3840 x 2160 @24 fps. The TV refreshes @30 fps. This will cause the two to be out of sync on refresh rate. It won't be too obvious that something isn't right until you start to use your mouse or do something motion oriented like dragging something across the screen. It will have a lot of lag. Too much.
With tweaks to your Xserver configuration you can over ride this in favor of using the 30 fps options it also supports. Since making this adjustment I find the lag problem isn't there anymore.
Last notes go to video performance. I can see sheering on some videos. Video is not awesome with this rig but tolerable when using 1080i resolution. I test this in a 1/4 size window on you tube and set the video resolution to 1080i. The video is reasonable but not good. I have watched portions of 1080i movies and they were occasionally marred by sheering in the video window. Occasionally a little frame lag. That takes the onboard processor out of contention for a 4k/UHD home theater pc. If I set the resolution on both the graphics card and the TV to 1080i its a lot better (no longer UHD at all.) So still a contender in that resolution.
Overall the the graphics on the 4790k are doing a great job for my office/work applications and that makes this chip a dead on hit for my requirements. The video testing was for curiosity sake and given the frequency with which I would ever watch a video on this PC the performance on that front is acceptable. I just wouldn't use it for a htpc build for UHD without also using a high performance pci graphics card.
Powerful cooling is a *MUST* with Haswell, as these CPUs run HOT, especially under heavy AVX/AVX2 loading, as video rendering tends to do, hence the Noctua NH-D14. Regardless of the heatsink that you install on it, you need to ensure that the heatsink gets good, clean air.
Overclocking is a bit of a delicate ballet with these CPUs, as well. YMMV, but I had to lock my ring voltage to 1.2 or 1.3V, ring frequency to 4000MHz, memory voltage to 1.35V, and then I set the FSB to 100MHz with a 46x multiplier. All power-saving states off, core voltage @ 1.250 or 1.255V, and it's stable under 100% all-core load in the form of intense AVX2 load by way of rendering x265/HEVC video @ 1080p60.
Overall, an excellent chip that holds its ground very well, but has a few specific things to be aware of.

Aunque no hay mucho que comentar que no se haya comentado de este procesador, tanto en reviews, comparativas, benchmarks, etc. Es por eso que voy a plantear mi review desde mi experiencia. Además en mi caso, adquirí el ROG Front Base, y es una pijada muy guapa para completar una torre Gaming (ya que dispongo de una de las placas compatibles con este accesorio).
Lo adquirí reacondicionado, y de momento muy bien (prácticamente nuevo, y con los descuentos de estos días pasados, se facilitó la adquisición). Lo adquirí para llevar al máximo nivel mi placa 1150, y de paso comparar realmente de primera mano, sin fanatismos ni favoritismos, de la manera más objetiva posible.
Ha sustituido a un i5 4570T, en una Maximus VII Hero; y a su vez, ese conjunto ha sustituido a un FX8350 en una GA-990FX Gaming (adquirida también aquí en Amazon tras averiarse mi Crosshair V Formula).
A esto le acompaña un Crossfire de R9 290, y es precisamente por ésto el principal motivo de la adquisición. En single thread Intel supera a los AMD, y quería comprobar cuanto incrementaba la estabilidad en el Crossfire con respecto al 8350.
Sinceramente, he de decir que ha mejorado, sobre todo en DX11 y anteriores; no siendo una mejora muy notable en DX12 con respecto al FX8350 (se nota que DX12 está bien optimizado para multiprocesamiento).
Tomando como referencia 3DMark, con TimeSpy, la diferencia es de unos 400 puntos (misma RAM, mismas GPUs). La puntuación del útlimo test que hice fue de 6891 puntos (siendo algo superior que un i7 4790k con un sli de GTX980, según la web oficial).
En cuanto a temperaturas, muchos usuarios hablan de que son muy frescos y tal, pero se calientan igual que los AMD cuando les metes carga de trabajo. Lo tengo con la misma refrigeración líquida que tenía el FX8350, y adquiere las mismas temperaturas (teniendo en cuenta que el AMD lo tengo Overclockeado a 4'6 Ghz, y el i7 4790k está sin OC).
En conclusión, y aunque aún no he podido trabajar mucho con él, es muy buen procesador, aunque sigue siendo un poco caro. No obstante si tienes una placa socket 1150, y quieres llevarla al máximo nivel, éste es tu procesador. Es el mejor procesador para dicho socket, y aún da de sobra para hacer todo tipo de cosas (gaming, edición de video, virtualización...). Casi requisito el tener una placa base con chipset Z97 (para exprimir el procesador al máximo con OC).
As with my last chip this one comes in quite a unexpected small box(not sure what I was expecting). Within the box is the processor which is contained in its own transportation sleeve. Also contained within is the stock cooler and thermal paste. I replaced this paste with a market leading brand in lieu of a water cooler that I am waiting for. I have noticed that the fan can make quite a bit of noise and the processor temp will soar when it is stressed.
I have been impressed with the amazing performance boost that installing this CPU has given me and it is working very well along side my ASUS Gtx 970 Strix, with them tearing up all the games that i have on the highest settings. I am very aware that the majority of games at the moment do not require anything more than four cores but I chose this processor to future proof my pc a little. This processor has given me many options to upgrade my pc if I choose in the future.
This CPU can be overclocked, hence the K and again I don't state that I am an expert in this field but I have read instances of this CPU reahing speeds in excess of 4.5- 4.6 Ghz, with there being many other reviews and websites that can give more information than my basic knowledge, so please look to them:)
All in all, I am very impressed with the quality, power and ability of this chip, this is when paired with an equally capable pc build. The price of the chip is to be expected for both the name of manufacturer and quality of the product, I must complain about the need to buy a better cooling system and I think for the price it should be provided as part of the package, but that's just a small point. Great CPU and I am pleased with my purchase...
