Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA 1155 - BX80637I73770K

In July 2013 I built 2 identical desktop computers (one for me; one for my wife) based on the ASUS P8Z77-V Pro motherboard (MB) (8 GB RAM in each machine). The machines were constructed from entirely new components, as listed below. The components were purchased from various on-line retailers, primarily Amazon.com, Newegg.com, and BestBuy.com. Both machines have been up-and-running now for roughly 1 month without problems. I have yet to flash any BIOS's. I have run simple tests on nearly all components; virtually everything has worked "out-of-the-box".Before getting into the hardware review, I'll provide a bit of background. I am an electrical engineer, and the assembled machines were scoped to be dependable work horses -- as opposed to gaming machines. I built my first desktop machines back in the early 1990's. I have always used Intel and ASUS motherboards, due to their reputations for reliability; recently I have used ASUS exclusively.The machines currently dual-boot Windows 7 Ultimate (SP1 64-bit) and Fedora 19 (64-bit); both OS's use UEFI secure boot. I don't currently run VMware or VirtualBox, though I may later on. Currently, I am not overclocking the machines in any way, though I may do so in the future; hence I cannot comment on their suitability for such.Here are the principal hardware components for the machines:Case: Corsair 650DPSU: Corsair AX750 (Gold)MB: ASUS P8Z77-V Pro (MB rev. 1.0; AMI BIOS rev. 1805)CPU: Intel i7-3770k (3.5 GHz quad-core LGA 1155) (model BX80637I73770K)RAM: Corsair Vengeance Black [16GB (4x4GB) 240-pin DDR3 1600MHz 1.5v low profile] (CML16GX3M4A1600C9B)Hard disk: Western Digital 1TB SATA3 (WD1002FAEX) (no RAID system)GPU: ASUS GeForce GTX 660 (GTX660-DC2-2GD5)DVD burner: ASUS DRW-24B1ST (OEM)Keyboard: Saitek Eclipse II Backlit keyboard (USB)Radio mouse: Logitech V450 Nano Cordless LaserI also elected to install the following additional components:CPU cooler: Cooler Master Hyper 212 EVODual-port NIC: Intel® PRO/1000 PT Dual Port Server Adapter (EXP19402PTBLK)USB 3.0 pass-through cable: USB 3.0 20-Pin MB header to 2 Type-A Female Connectors Y-CableComments:Cases: We looked at a number of different cases at brick-and-mortar stores before settling on the Corsair 650D. (I've used Antec cases in the past; the Cooler Master cases were strong contenders this time around.) The Corsair 650D cases are solid and nice-looking from a conservative perspective (not flashy); gamers would probably consider them boring. Since the P8Z77-V Pro does not offer eSATA support (and USB 3.0 has better specs than eSATA), the eSATA drive caddy on the top of the case is not useful for us. Also, I found the quick-release mechanisms for the front drive bays to be unreliable: I secured the DVD drives the old-fashion way -- with screws. However, we really do like the see-through side panel feature. Finally, the 650D was designed before the USB 3.0 motherboard header configuration was finalized, therefore the USB 3.0 cables that connect the front-panel USB 3.0 ports won't attach directly to ANY motherboard. To remedy this, I bought the adapter cable listed above; if you want one, here is the Amazon link:http://www.amazon.com/8-inch-20-Pin-Motherboard-Connectors-Y-Cable/dp/B007PODI1W/ref=sr_1_3?s=electronics&ie=UTF8&qid=1356639600&sr=1-3&keywords=usbPSU: I believe the AX750 series has been discontinued now. I chose the older Corsair power supplies based on their reliability and the fact that they used Japanese capacitors; I couldn't determine whether the new Corsair PSUs had quality capacitors. The fan in the AX750's makes a clicking sound at very low rpm -- typically only occurs just as the machine starts up. Other than that, they are extremely quiet and solid units. Also really like the modular cable feature; fewer cables in the case.Motherboard: I spent many hours reading motherboard reviews and comparing MB feature sets before choosing the P8Z77-V Pro. I mostly looked at ASUS boards, including some in their Workstation line. (I know that there are many other quality makers of MBs available, but ASUS retains its status as one of the best, and, with just 2 choices of manufacturers, the number of offerings simply becomes mind-boggling.) Ultimately it was a combination of reasonable price and a simple yet versatile feature set (PCI slots, SATA buses, video ports, peripheral ports, etc.) that drove my choice.I've found the P8Z77-V Pro to be solid and pleasant to work with. So far no problems with bad slots or ports; the on-board video and audio work fine. Some of the P8Z77-V Pro comments I saw online complained about slow upload/download problems associated with the on-board networking (I also turned off the MB wireless LAN (Wi-Fi) feature in the BIOS, so I cannot comment on its functionality; this feature also gets many negative comments in P8Z77 blogs.)The MB AMI BIOS is well-designed and fairly user friendly. I was disappointed to see how many unnecessary 3rd-party software add-ons were included on the ASUS CD-ROM that contains the MB device drivers. (Experienced machine builders typically ignore the CD-ROM and get the latest device drivers from on-line repositories, but I tend to only flash-and-patch on an "as-needed" basis.) Anyway, after some web research, I opted to NOT install the following ASUS CD-ROM software features:Network iControl (Many on-line posts recommend disabling this.)LucidLogix Virtu MVP (As far as I can tell, this only helps gamers -- and even a fair number of them recommend NOT using it.)CPU: The Intel i7-3770k CPU represented the best price/performance trade-off available last spring. The "k" model offers better overclocking capabilities; if you are interested in running VMware or VirtualBox, you might want to go with the straight "3770" model.RAM: I opted for the Corsair memory on this go-round simply based on reputation and price. I haven't yet seen a single memory hiccup. In the past I've used Crucial. You want to buy the RAM in packages of matched modules (to avoid timing conflicts). Also, use of the "low-profile" modules avoids potential MB space conflicts when mounting a CPU cooler.Hard drive: I've used Western Digital drives exclusively for years. They are fast, quiet, and I'VE NEVER HAD ONE CRASH even though I frequently have 2 or 3 drives in my machines. (I cannot say that about other HD lines.) (Note: I religiously replace my HDs at the point that their warranties expire; the 2 desktop machines I am currently replacing have been in service for over 9 years, and each one has had the primary drive replaced twice.) I saw some on-line reviews that stated that the WD1002FAEX model is noisy. The reviewers must have gotten bad units: the two that I just installed are whisper quiet. And the WD1002FAEX comes with a 5-yr warranty.GPU: We may not play games at home, but we often watch uTube and DVD videos. I chose the ASUS GeForce GTX 660 based primarily on reviews. (I went the nVIDIA route, as opposed to AMD graphics, because of nVIDIA's strong reputation for UNIX/Linux OS support. ATI's support was abysmal, and AMD seems to be following suit.) The card runs cool and quiet, and it even came with a cable adapter for my old 21" CRT monitor. We get gorgeous, even-color images at 1600x1200 and higher resolutions.DVD burner: No issues so far with the DVD drives, though we haven't tried burning anything yet. The burner software provided (on CDROM) with the drive isn't worth much; we're going to try Ashampoo (free) this time around.Keyboard: I bought my first Saitek Eclipse II at least 7 years ago for doing work with my laptop while reclining on the couch at home. We now have 3 of them. The keyboard gets decent reviews on-line; some reviews complain about the paint wearing off the keys. The keys on my original one show no signs of wear. I'll admit that only the violet backlighting color works well when typing in the dark; perhaps that's why gamers give it mixed reviews. For us, the keyboard offers good heft, nice tactile response, and longevity.Mouse: Like the Saitek keyboard, I bought my first V450 Nano mouse for use with my laptop. Soon after, I replaced the corded mouse on my old desktop machine with a second one. We now have 3 of these in the house. Recommendation: The mouse runs on a pair of AA batteries: get a decent battery charger and some rechargeable AAs.CPU cooler: Although we currently live in a city where outside temperatures rarely surpass 80 degrees (F), it was only a few years ago that we lived in an area where temperatures regularly exceeded 100 F in July and August. Also, the Intel i7 LGA 1155 CPU series reportedly has poor heat dissipation characteristics. Hence I opted to forego the heat sink that came with the Intel CPU and instead deploy the Cooler Master Hyper 212 EVO cooling system in our new machines. The Hyper 212 EVO is one of the cheaper (but still well regarded) cooling solutions on the market; it should suffice as long as we don't seriously over-clock the systems. (I also opted to use Arctic Silver 5 Thermal Compound rather than the thermal compound that Cooler Master provided with the Hyper 212 EVO. The Artic Silver 5 compound is among the most effective products of its type; many of the expensive commercial compounds available perform worse than mayonnaise. See link below.)[...]

I know this is an old core. It is the fastest I7 that my dad’s computer could use. It originally had an I3 so this zipped it up quite a bit. He only surfs and watches YouTube so it’s just fine for what he uses it for. Decent price as older top end cores for this gen are really expensive, but didn’t want to do a new rebuild for his uses. I paired it with a Noctua low profile cpu cooler and it’s been fine for 2+ years and runs cool. Great quality and quick shipping.

The i7-3770k is a fantastic processor! Out of the box (with no overclocking), I got a Windows Experience Index rating of 7.7 (on a 1.0 to 7.9 scale). The CPU installation is quite easy and the 'k' at the end of 3770k means the processor is unlocked for easier overclocking. The HD 4000 graphics are also great! I got a Windows Experience Index of 6.5 in both graphics categories without the need for a discrete GPU (if you don't need serious graphics performance, this processor could save you money on a graphics card!).This chip laughs at anything I give it. It can transcode a 1 hour 45 minute HD video in just a few minutes without using most of the full force of the processor (my particular trial lasted about 11 minutes and utilized just under 20% of the CPU power including my internet browser).I do have a few light reservations, however. First, the price is going up (at least on amazon) and will eventually drop off a bit. The recommended retail price (given by Intel) is around 320-330 (similar to what the i7-2700k goes for).Second, the Intel Core i5 3570K Processor 3.4 4 BX80637I53570K shares a lot of the great features of the i7-3770k for a lot less money (100 dollars or more cheaper). You lose 2MB of L3 cache, 100 MHz in clock speed and turbo speed, and the hyper-threading technology when you move down to the i5-3570k. But you keep the HD 4000 graphics and the unlocked processor for overclocking (the i5-3570k might even be slightly better for overclocking purposes which could make up for its 100 MHz decrease, and even some of the hyper-threading). In general, if you have software which can fully utilize 8 threads, this processor is probably worth the extra cost.Third, the ivy bridge lineup does run a bit hotter than sandy bridge, but this is completely expected from a smaller architecture. This shouldn't be much of a problem (very good overclocking with air is still easily possible and extreme cooling allows for some incredible results) but upgrading from an overclocked sandy bridge might not make much sense - unless the HD 4000 graphics are worth it for you.Overall, this is one of the greatest processors available today (definitely the best performer on its socket type). Any processor which beats this one costs at least several hundred dollars more and doesn't gain nearly that much in extra performance. So, if you can handle the somewhat higher price than the i5-3570k, get this beast of a CPU!

Using Gentoo genkernel and =sys-kernel/gentoo-sources-3.4.9, I was able to time a kernel compile within six minutes using make -j3 or -j5. This CPU sings with:Corsair Vengeance 32GB (4x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMZ32GX3M4X1600C10)ASUS P8Z77-V LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel MotherboardI tried mounting ~5GB of the RAM as /var/tmp/portage, and I don't think it increased compile time at all, if anything the compile time was slightly more by a second or so. I'm guessing, it's all the transactions between the buses creates more overhead then using the hard drive for untarring and building the sources on.HD4000 graphics chip also run pretty compariable to, but not as fast as a NVidia GeForce 6200GS AGP. However, the HD4000 appears to have absolutely no problems playing HD video with apparently little CPU usage.Package managers for Operating Systems, usually coded in Python or scripting, complete your command incantation within a second or so!VirtualBox runs very well having a Windows XP guest use only one CPU! WindowsXP runs as if there were no host and then some. VirtualBox is able to use the VT features of the CPU, even though this P8Z77 chipset board has limited VT features. The CPU usage during using one virtual guest was also extremely minimal. Memory usage was also somewhat minimal, which makes me really glad I bought the 32GB maximum amount of RAM for this board.The main reason I needed to upgrade my 2x750 P3 440BX w/ 1GB RAM was to be able to surf the web even though I use noscript/adblock with Mozilla Seamonkey. Now, my current setup with DWM (Window Manager) runs exponentially faster and I still have no desire to use Gnome or KDE. But, I can use Gnome, KDE and WindowsXP without any problems with this CPU with all eye-candy features turned on!This chip seems to run about ~80-82F with an after market third party fan and well ventilated case as listed below. One website (phoronix.com) apparently using the stock fan performed a comparison against AMD, had temperatures of around 100-122F. But the case they used for the review was one of those tiny tight mini cases. The i7 3770K w/ HD4000 was the top performer.Cooler Master Hyper 212 Plus CPU Cooler with Four Direct Contact Heat Pipes (RR-B10-212P-G1)Cooler Master HAF 922 Mid Tower Computer Case with USB 3.0 Ports (RC-922M-KKN3-GP)Supposedly, this CPU w/ HD4000 will hardware encode and decode H.264 video using vaapi. (See Gentoo USE Flag vaapi.) Also, MPEG2 is also hardware decoded.Very pleased I stuck with everybody else and bought this CPU. (Tomorrow, there'll be a CPU double the speed of this on.)2012.11.07 - I just returned the ASUS and bought a Gigabyte GA-Z77X-UP7 motherboard. I can now do "make -j8" compiles without any apparent issues. I'm not sure if the source of the problem is the additional video card off-loading graphics or the previous ASUS's motherboard bus. I'm thinking the later as I did try separate attempts with the iGPU & video card. The ASUS P8Z77-V has a legacy PCI bus, and I saw a few other issues, but am dumb founded as it shouldn't be an issue. Anyways, it's nice to see "make -j8" loading up all CPU's here. ;-)Gigabyte LGA 1155 DDR3 2400 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Extended ATX Motherboard GA-Z77X-UP7

This process that is very, very powerful and wearing care from gaming shdlwm and for bmd type and more popular games. I like this chip said because it's so curl. Shdlwm and shdlwm. So it has only in only one thing. It has only one big crash or on the metal plate. And it is only God that is very good is the the processor is very cured, very performance and very, very pretty like another ones and I like this, but these by these by these guys buy this because it is. Good very good , good good good good good good good good good good

I'm a software developer and typically enjoy building my own systems. My previous system was an overclocked i7-920.This processor is FAST... though I wish Intel had more competition!This is a very good processor with PCI Express 3.0 support. The matching Z77 chipset also adds features that I didn't have on my previous i7-920 machine, like USB 3.0 and SATA 6Gbps. Most of the Z77 motherboards support up to 32GB of RAM, but, for unknown reasons, I had instability with 32GB of RAM and am now using 16GB and 4x4GB sticks instead of 4x8GB sticks.I easily overclocked this processor (all 4 cores) to 4.4 Ghz using only a +.05 voltage offset in the BIOS on my Asus Z77 Sabertooth motherboard and found it stable with IntelBurnTest and Prime95. I'm sure I could have gone for more, but I like an energy-efficient, conservative overclock. A "free" 900 Mhz increase isn't bad and at this voltage with a Cooler Master 212 EVO cooler, the CPU temperatures are well under control. This scores a 7.8 in the Windows 7 Processor performance score (the highest is 7.9 which is hard to obtain unless you have a 6 core+ processor).I always use a 3rd party cooling solution, though I'm sure the provided fan and heatsink is sufficient when not overclocking. The reason I like 3rd party solutions is for greater cooling power (useful when overclocking) and for quieter operation, so consider a better cooler if you want to overclock or want something that might be a little quieter.The non-"K" version has some additional features, but for 99%+ of people who overclock, I doubt giving up the unlocked multiplier (the "K") is worth it.

I purchased this processor to replace an old Q9965 I'd had in my LGA 775 build for years. I've got to say I am completely satisfied with the purchase.This processor is fast, like blazingly fast. I do alot of gaming and animation and this thing just crushes whatever I throw at it. I'd really get my monies worth if I did video editing or used more threading intesive programs, but part of the reason I got the i7 over the i5 of comparable quality is just because I wont buy another processor for a few years and I figured why not, maybe in the future I will use more threading intensive applications. Took my Windows Experience Index up to 7.8 out of 7.9 .I waited for a while to upgrade to the Core i series of processors and really wanted the Ivy Bridge so I ended up waiting an extra few months to snag this thing. Can't say that I regret purchasing over the Sandy Bridge, performance increase comparatively is negligable though. About 3-6% better performance out of the Ivy Bridge. The Ivy Bridge also runs hotter than Sandy Bridge, but even with the stock fan it stays cool enough under load.Integrated graphics (especially with a Z77 chipset motherboard) are a pretty neat feature, however I do not utilize it as I'm running with a 470 gtx. The really nice thing about this processor is that it has native support for USB 3.0, SATA III, and PCI Express 3.0 right out of the gate. Making it relatively future proof for at least the next few years (granted your motherboard has support). So when I do get that new graphics card I dont have to worry about compatibilty issues :)I would highly recommend purchasing this processor if you're looking for a new Ivy Bridge. I would not however recommend upgrading from a Sandy Bridge for this, as the difference in performance is minimal at best. No need to speed another $350 on a cpu that does what your old one does except 4% better. But if you're still stuck 2 or 3 generations back as I was, this makes a world of difference, you wont be sorry.

Good:If you are looking for a powerful CPU and don't want to get to go for X79 6 core this is it. It outperforms my friend's i7 3820 by around 10% in benchmark tests. Combine it with a good video card and this will play the latest games and video edit all day without problems.Sort of bad: the temps will increase greatly with even a small voltage increase during overclocking. If you're overclocking at all you really need a fairly high end cooler. I'm using the Corsair H100i with Arctic Silver paste and I'm still getting near 75C at 4.2 Ghz and 1.1V at 100% load. These processors are more resistant to high temps than the older generation but is still a slight issue.Value: If you are on a budget you can get the i5 3570k for $100 less. The i5 will perform the same in most games at the current time but it does not have hyperthreading so it will be slower in video editing and other CPU intense. So this chip may not have the best price/performance ratio but I think it will be more future proof than the i5.Final Thoughts: Regardless of this heat issue this is still one of the best Intel processors without spending an insane amount of money on a 6 core and X79 motherboard. Its better than the current quad core X79 cpu the i7 3820 but its not as good as the new Haswell 4770k, the Haswell chip is around 10% faster than this one but is $30 more at the moment and the motherboards are slightly more expensive as well. If you are building a new rig this will be great for years to come, definitely worth a buy if you want to edit videos and the hyperthreading will probably be beneficial for future games
