Intel Core 2 Quad Q9550 Yorkfield Quad-Core 2.83GHz LGA 775 95W Desktop Processor BX80569Q9550

Crush your enemies, climb the tower of paperwork, or do both at the same time. Intel's Core 2 Quad Q9550 not only makes it possible, it makes it easy. The Core 2 Quad Q9550 has quad cores that run at 2.83GHz and shares 12MB of L2 cache.

Quad cores means true multi-tasking and multi-threading. Tasks or threads get their own core; no more sharing one core and set of clock cycles. This lets you turn your system into the ultimate home entertainment center PC. One core handles the usual action on your operating system, while the second can play a DVD on the TV, the third download a file from internet, and the fourth one sends audio to the kids in another room with no lags or stutters. All this is made easier with Intel’s advanced Digital Media Boost.

The 45nm Intel Core 2 Quad processor is armed with Intel HD Boost, which implements new Intel Streaming SIMD Extension 4.1 (Intel SSE4.1) instructions for fast high definition video editing and encoding, enhance the multimedia performance.

  • newegg Intel Core 2 Quad-core Processor With four processing cores, the multitasking monster Quad-Core Intel Core 2 processor delivers fourfold the performance on highly-threaded applications, taking your desktop PC experience into a completely new realm of mega power. The powerful processor delivers serious performance on the ultra-demanding games of today and tomorrow. The innovative 45nm quad-core technology optimizes thermal performance for reduced power consumption and noise.
  • newegg Intel Advanced Smart Cache Intel Advanced Smart Cache Technology dynamically allocates the shared L2 cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from fast L2 cache, resulting in significantly reduced latency for frequently used data and improved performance.
  • newegg Intel Wide Dynamic Execution With Intel Wide Dynamic Execution, each of the four cores can complete up to four full instructions simultaneously, improves execution speed and efficiency, delivering more instructions per clock cycle.
  • newegg Execute Disable Bit (EDB) Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
  • newegg Intel Virtualization Technology (Intel VT) With Intel VT, one hardware platform functions as multiple "virtual" platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.

5 out of 5 eggsOC For 5 Years And Going

Pros: - Easy to overclock
- No degradation even with good overclocks
-

Cons: There are none. It is an amazing sample of what humans can achieve when they put their minds together.

Other Thoughts: This CPU really amazes me even after all of these years in that it is going strong and there has been no degradation of the CPU even after a good overclock of 3.61 GHz @ 1.268V for nearly 5 years straight.Did I mention that this CPU has run at 3.61 GHz for 5 years with no degradation? Not one increase in voltage! Stable this whole time at the same voltage.
Running memory (G.Skill PC2-8500) at 1021 MHz = 400*(425/333)*2 @ 2.0V with timings of 5-5-5-15. Sure, it is rated for 1066 MHz, but, eh, I only get so many options in the BIOS.

5 out of 5 eggsAges like wine

Pros: I built my rig in early 2009 and I'm still running this baby OC'd to 3.4ghz across each core. I could go higher but honestly I haven't needed to. And with almost six years of stability I can say this is the best processor I have ever owned.

I am nearing the point where I need a new rig but my CPU is not the bottleneck I'm running into. This performs well regardless of how many generations old this baby is.

Cons: I just wish I could send it back to Intel, have them inject some "i7 tech" and rework it for an LGA1150 slot. This would be my version of "Devil's Canyon"

Other Thoughts: This is the only computer part after building four or five PC's that I've felt the need to put up a review on.

5 out of 5 eggs4 years of awesome service

Pros: Had this for four years. Still running strong. Put this with my new 7950 on a 780i mobo and it's able to keep up with Ivy bridge FPS in games, even FC and Crysis. I've got out stable at 4.03GHz and verified online through cpuid. Don't plan to upgrade for another couple years. I will likely never own a better CPU that will keep up with new programs and games as long as this one did.

Cons: Nope!

5 out of 5 eggsBought back in Jan 2010 and this CPU is still going strong

Pros: I paid $259 for this processor a few years ago for this CPU and I have not been sorry once. I mostly game (mainly BF 3) and watch movies on my rig and this processor does it all and more. I have the model with the E0 stepping and it has OC'd like a dream. On stock settings, I can get the processor to run 3.6GHz just by tweaking the multiplier. With a few small bumps with the voltage and other settings, I get a solid 3.8GHz on air, with an aftermarket CPU cooler of course. An Evercool Transformer 4 CPU cooler to be exact (great cooler by the way). And I replaced the 2 120 mm fans it came with, they ran at 1000 rpm, with 2 that ran faster that I had laying around, made by Antec and run at 1600 rpm's and light up blue.

Cons: None.

Other Thoughts: With this processor, GTX 570, OCZ SSD, and 8 Gigs of ram, I get 40 FPS on BF 3 on ultimate and over 60 fps on high all on 1900 x 1200 monitor. It's going to be hard parting with this CPU to upgrade come next spring. I plan on passing this old rig to my little girl, so she can rock the Lego video games. =)

5 out of 5 eggsCouldn't be happier!

Pros: I've had this processor since June 2009 and it's been overclocked to 4.0 ghz for at least one year, 24/7. It's still cranking along without a hiccup. It's going to be hard to convince myself to upgrade to Ivy Bridge during the coming winter, but I believe that I still will.

Cons: None.

5 out of 5 eggsAwesome CPU!!!

Pros: Awesome CPU. Really speeded up my system. Very noticeable difference.

Cons: None performance wise. Maybe the price?

Other Thoughts: I upgraded from the E8400 Core 2 Duo to this CPU. My cpu Aero Score went from 6.6 to 7.2 Everything runs a lot faster. I never overclock anything. No Need To.. I didn't want to spend $600+ for a new Mobo, ddr3 memory and an i5 or i7 cpu. This was the poor mans upgrade!!! And a good choice it was to. I couldn't be happier!!!
