Intel Core 2 Duo E4400 Allendale Dual-Core 2.0GHz LGA 775 65W Processor BX80557E4400

  • 800MHz FSB
  • 65nm Allendale 65W
  • 2M shared L2 Cache

Make the universe submit to your will. It doesn't matter if it's the newest video game or multiple spreadsheets, documents and database files, Intel’s Core 2 Duo processor can manage it with ease. The two cores run at 2.0GHz each and share 2MB of L2 cache.

Two 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 can play a DVD on the TV, the second sends audio to the kids in another room with no lags or stutters. All this is made easier with Intel’s Digital Media Boost.

All of that power won’t do you any good if managed poorly. That’s why Intel developed Wide Dynamic Execution and Smart Memory Access. WDE delivers more instructions per clock cycle while SMA optimizes memory bandwidth.

  • newegg Dual-Core Processing with 2MB L2 Cache The Intel Core 2 Duo E4400 processor features two independent processor cores in one physical package running at 2.0GHz with 2MB L2 cache and a 800MHz FSB to provide truly parallel computing for enhanced multi-application performance.
  • newegg Enhanced Intel SpeedStep Technology (EIST) EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.
  • newegg Intel Extended Memory 64 Technology (Intel EM64T) Enhances next-generation IA-32 platforms with 64-bit addressability and related instructions, allowing flexibility for both 64-bit and 32-bit applications and operating systems.
  • 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.

5 out of 5 eggsGreat Midrange CPU

Pros: I ran this processor at 2.66GHz (~E6700) and everything ran smooth. Didn't use the stock cooler because of overclock. Just what I needed for a midrange PC. I received the M0 stepping, better for overclock.

Cons: None.

Other Thoughts: Specs: EVGA 680i, E4400@2.66GHz, Zalman CNPS9700NT, EVGA 7800GTX, OCZ GameXStream 700W, Patriot Extreme Low-Latency DDR2-800, Windows XP Pro 32-bit.

5 out of 5 eggsIt's Intel. 'Nuff Said.

Pros: Works perfectly. Has a decent cache size, and is one of the cheaper core duos. I have yet to get it to 100%, except via Intel's Thermal Analysis Tool.

Cons: The box wasn't recycled.

Other Thoughts: The stock HSF combo works flawlessly, with Arctic Silver 5. Unless you are overclocking, it will suit your needs.

5 out of 5 eggsJust What I Was Looking For

Pros: Inexpensive but can run most games out there at low settings inside the right computer. I was looking for a CHEAP new computer and got this guy thinking it was the weak point to my machine. I was wrong.

Cons: Not as powerful as what I'm shopping for now for my new computer (Quad-Core)

Other Thoughts: I've overclocked it, it overclocks.

5 out of 5 eggsBuy cheap, then overclock!

Pros: Sweet! Installed on MSI P6N Mobo with ARCTIC COOLING Freezer 7 Pro fan. E4400 overclocked to 3.0Ghz, stock voltage, temp stays under 42*C even after 24 hrs running Prime95 torture test. Could probably push it more but why.

Cons: Doesn't restock the fridge with beer!

5 out of 5 eggsOH SNAP!!!!

Pros: %40 OC!!!! M0 stepping I am sitting at 280 FSB x 10 Multiplier Easily with the Abit AB9 PRO motherboard. Processor after 4 hours of Orthos stress test at %100 for both cores never broke 50 degrees. idle 32-35. Paired with 2 GIGS of Supertalent DDR2 800 with a 4/5 divider. I could easily break 3.0 GHZ, but have not had the need as this is a 24 x 7 overclock.

Cons: NONE!!!!!! Just sad that intel is discontinuing this chip, but thats actually good cause prices are going to drop when it hits EOL.

Other Thoughts: BUY IT, I have the new M0 stepping and its still a beast of an Overclocker, no thermal issues whatsoever. Just know what your doing.

4 out of 5 eggsPretty good processor

Pros: This processor did anything i wanted it to. I never got past 50% usage for the longest time, doing anything too. When i first built my computer and put this processor in it, the first thing i did was open like 10 firefoxes just to see how my processor would hadnle it and it only got up to like 20% lol. It's a great processor. Great for system builder beginners.

Cons: Latelys it's be crapping out on me and i don't know why. It could be a program i can't find that's hogging up all the cpu usage but i don't think that's it because it will randomly go to 0% cpu usage when it should be doing something and i can get it up to 100% just by highlighting items on my desktop. It's like it's growing old or something. It's running really cool too so i don't know what the problem is at around 45C. If someone could help me that would be really great.

Other Thoughts: I'd give this processor 5 eggs but i really just don't know what's up with it that it has to start acting up on me lately ):

5 out of 5 eggsgood for the money

Pros: This processor is great for the money if you want the speed of the core 2 duo. Huge speed increase over the celeron D 356 that I had.

Cons: Don't use this on a mobo with a VIA cipset of any kind because it doesn't overclock at all.

Other Thoughts: look at the other processors in the E4XXX series because you can get 200 to 400 MHz more at a much cheaper price!

1 out of 5 eggsComplete Bull$%*)

Pros: I'm trying to be objective here, but not really finding anything...

Cons: Way too much hype about Core 2 Duo... My AMD 2.6 smoked this thing... And for $20 less. Not to mention the temps... Yes, I changed the stock thermal pads w/ Artic Silver5 grease and flashed Bios to most current... Still running 60C.

Other Thoughts: This was my first build with Intel and I am TOTALLY dissapointed with them. Hell, the P4 single Core moved faster than these... With all the hype and fanboys out there, I thought that this was going to be the second coming as stated in THE book (Not the KORAN)... Complete disappointment. My AMD 2.6 smoked this in PCMark 05 by 600 points, as well as Ripping and Encoding both DVD's and CD's. Intel machine ripped and encd'd Days of Thunder in 20 minutes. My AMD did it in 10 minutes. Oh yeah... $20 cheaper. Here's the stats:
AMD 5200 x2 2.6, Gigabyte Mobo, 2 Gb Corsair RAM CL5, WD 80, WD 500,EVGA 8800GTS
VS.
Intel E4400 2.0 GHz, Gigabyte Mobo, 2 GB Kingston RAM CL 4, WD 120, WD 250, EVGA 8600

With all the talk on the reviews... I expected better. A complete letdown
