## Description

Product Description Specifications: Mfr Part Number: BX80580Q9400, Process Type: Intel Core 2 Quad Processor Q9400, Frequency: 2.66 GHz, FSB: 1333 MHz, Cache: 6 MB, Process: 45 nm, Socket: Socket 775, Power Consumption: 95 W, Package: Retial, This processor is a Quad Core Processor, This processor supports Intel SpeedStep Technology, This processor supports Intel Extended Memory 64 Technology (EM64T), This processor supports Intel Virtualization Technology, This processor supports Enhanced Halt State (C1E), This processor supports Execute Disable Bit Capability, This processor supports Intel Thermal Monitor 2 desertcart.com desertcart.com Product Description The Intel Core 2 Quad Q9400 brings four computing cores running at 2.66 GHz in a single processor for the ultimate in efficiency and performance. It features 6 MB of L2 cache and a 1333 MHz front side bus, and it uses the LGA775 socket for wide compatibility with motherboards. The processor features Intel's 45nm architecture and delivers multimedia experiences with greater speed and responsiveness. With the Q9400, demanding users can now accomplish more in less time.With four cores, you'll experience outstanding performance and better efficiency. The Core 2 Quad Q9400 lets you enjoy a smooth and high-quality multimedia experience. Intel's Intelligent Power Capability ensures optimal energy efficiency. Stunning Performance Runs Latest Software with Ease Starting with Intel's revolutionary new high-efficiency, high-performance 45nm processor technology, Intel engineers decided to go one step farther in the performance department. By including 6 MB of shared L2 cache and a front side bus speed of 1333 MHz, the Q9400 processor pushes the technological innovation envelope farther than ever before. For users, this means the latest and most advanced software applications can open and run faster with superior responsiveness. When used with the latest multimedia software and next-generation games, dropped frames, long waiting times, and stuttering performance are things of the past.New Technologies Provide Higher Performance and Better Energy Efficiency By using hafnium, a naturally occurring element, Intel engineers were able to shrink the size of new Intel processors and pack more computing technology into less space. The processor also features Intel's Intelligent Power Capability, which allows it to turn off parts of itself when it isn't in use. The result is improved performance with less energy wastage and a reduction of heat and noise. Intel has packed the Core 2 Quad Q9400 with cutting-edge technologies for better performance. Wide Dynamic Execution allows the processor to do more tasks simultaneously by enabling the delivery of more instructions per clock cycle. Intel's Advanced Smart Cache technology improves performance by physically placing data closer to the processing cores. And Smart Memory Access, which increases available data bandwidth, means you'll experience less slowdown while multi-tasking, so you can get more done.Multimedia Acceleration for Faster Content Creation If you are editing HD video, manipulating professional-grade photos, or working with music, the Q9400 will let your computer keep up with your imagination. The processor features Intel's Advanced Digital Media Boost for accelerating performance of a wide range of applications including video, gaming, speech and image, and photo processing among others. Additionally, Intel's HD Boost technology further improves the performance of SSE4-optimized applications, such as video editing and encoding in high definition.Fewer Multi-tasking Slowdowns With four processing cores, you'll be able to juggle more projects and more applications without experiencing the slowdown that you typically see with traditional single-core processors. Processing tasks are split up and distributed to the four different cores so the Q9400 doesn't get bogged down.Get a Leg Up on the Latest Games Next-generation gaming is more than just pretty environments and smooth motion. Behind the incredible visual realism of waterfalls or the unlucky ricochet of a bullet are intense, high-speed calculations of asset streaming, terrain generation, 3D rendering, and physics effects. When running select next-generation games, each of the cores in the Q9400 can be dedicated to each of these individual processes, resulting in smoother, more lifelike graphics and further blurring the line between virtual and reality. The Intel Core 2 Quad Q9400 is backed by a three-year warranty.

Review: Good Performance Boost Compared to E8400 Dual-core! - Replaced the well-known and reliable Intel Core2Duo E8400 65-watt dual-core cpu with this Core2Quad Q9400 95-watt quad-core. Got a nice performance boost and temperatures remain stable. Apps open a little quicker and snappier than before, video plays smoother, and multi-tasking is very noticeably improved. It's worth noting that it went into a small form factor Lenovo M58p business PC. These Lenovo models have their own heatsink/fan attached to the chassis/frame. I noted in the maintenance/service guide that the heatsink for a 95-watt cpu (Q9400) is a different part number than for the 65-watt cpu (E8400). But, the existing Lenovo heatsink seemed substantial enough, so took a chance and installed the Q9400. Seated it using Noctua thermal paste so that may help a little in keeping it cool. Depending on room temperature, the Q9400 idles between 36°C. - 38°C. With several browser tabs open and video playing fullscreen temps are 56°C. - 58°C. Much the same when doing multi-tasking Office work. Edited about 4GB video recording, and that pushed the temp up to about 64°C. This is very satisfactory for a small form factor PC. For a small investment the Q9400 is definitely a bargain for boosting performance and extending the life of an older PC. Recommended.
Review: Probably the best value for any processor at this point in time... - I spent several days researching the differences between all the current Intel processors before finally deciding on this one. The problem is that most of them are very close in price so it's difficult to make a decision on price alone. I found that when you consider all the factors like number of cores, mhz, cache and price, this is the best option. It is fast enough for the most demanding multimedia and games and has all the energy saving features so you won't waste energy while doing something like typing word documents. If you are building strictly for gaming then you should probably spend the extra $30 on the Q9550 even though this one will do quite well if paired with a high end graphics card. On the other hand, if you are building as a office type computer for email and word processing etc, you should probably save the $20 and go with the E8400. This one is the perfect middle ground for great performance at a great price!

## Questions & Answers

**Q: What does the box include, does it include a fan and heat sink.**
A: The Core 2 Quad is like a stripped down version of the Core 2 Duo except that it only comes with the AUTH Heatsink (not OEM) but no fan,you would have to BYO. I would recommend ZALMAN Q or Z series.       GOOD LUCK    JOHN VELLA

**Q: will this work on an lga ll5x socket?**
A: Normally NO for the pin placement is different,especially the #1 pin (Reversed) as per Motherboard socket, but there is a solution. INTEL manufactured a "RAISED PIN PLATFORM" to convert the lga 1100 to lga115x. The RPP was manufactured by INTEL during  march/2011 through February/2015 not certain past that time.

**Q: Is compatible lga775 slb6b? is for biostar g41d3 v6.2...**
A: i put them into my Lenovo M72s computers which take a Gen 2 or Gen 3 chip  so if your motherboard is looking for sandy or ivy these should work  see if the manufacturer says gen 2 or gen 3  thats all I got from Lenovo

**Q: if I were to upgrade from this, what would be my options? thanks**
A: It would really depend on what you want to do with it. There are many options in the Intel quad series that are better than the q9400. However the LGA 775 socket also can use the Xeon series processors which are very nice and powerful. And if you want to go to the absolute best but most expensive you could go with the Intel extreme series of processors. It really depends on how much speed you want and how much cache.

### ⭐⭐⭐⭐⭐ Screaming Processor!
*by F***D on February 13, 2010*

I can't believe how much better this is than my E7500 @ 2.93mhz. Even when I had it OC'd to 3.4 it couldn't hold a candle to this puppy. Don't be thrown by the slightly lowered speed (2.66mhz), this thing screams. Paired with a OCZ Vendetta 2 cooler, and my temps are 26C idle and 37C under load (load being Mass Effect 2 or Dragon Age at max settings). I haven't OC'd it yet because I'm so impressed with it's stock power, but I'm sure I'll start playing with it in a week or so.
