Intel Core 2 Duo E8400 3GHz Dual-Core (EU80570PJ0806M) Processor Only

I go this because my old CPU didn't support VT-x, which I needed for kvm.I have an ACER Aspire M5640/M3640 with an MCP73PV motherboard. No issues installing the hardware but I did need to update the BIOS to get support for VT-x. Fortunately ACER does have a BIOS upgrade available.**When you flash your BIOS, be sure to check the box to clear the BIOS md5sum!**If you don't you'll get an error during boot and the BIOS will load with the default values. In my case that resulted in booting off the wrong drive which didn't have a bootloader setup in such a way that I could boot back into Windows or Linux. Somehow I had my boot loader configuration setup in such a way that it would only work when booting off of the drive the BIOS, by default, didn't want to boot off of. So I was reduced to looking up the grub commands I needed on a laptop and carefully typing them into the grub prompt, just so that I could boot back into Windows and run the BIOS tool again.Once that was taken care, everything just worked. No issues and I can run the Android emulator. A great upgrade for $20.

The shipment arrived much faster than promised. In my case it arrived in 3 days. Not bad for shipping from West to East coast. The processor appears to be new as promised. The packaging is minimalistic as it is expected for OEM packaging. If you want it with the box you need to buy the boxed item for 3 or 4 times the price. Installation couldn't be easier. This was the first time I changed a processor and it is very straight forward. Motherboard and Win 7 recognized the new hardware an without any problems. Nice upgrade for my old PC which is plenty fast for me again. I also bought a new fan and solid state hard drive. Instead of spending several hundred for a new machine this PC will work for me again.

Awesome product! I was skeptical at first since this was the first time I bought from this seller but now I have to say wow, I'm glad I did. I got this product well packaged and in mint condition. Once I installed the processor on my pc it did not boot but it was my bad for not configuring the motherboard jumpers correctly. Processor is very snappy and I ordered 2 more. Definately a must buy to give life back to an older 775 socket. This processor replaced a pentium 4 2.66 GHz and its night and day. I also ordered an MSI GT 640 to replace an old 8400gs and now with 4 gigs of RAM my pc can run Battlefield 4 even though it is not my main gaming pc. I cannot recommend this processor enough and If you plan buying this product do it from this seller.

Ordered this CPU to upgrade a Core 2 Duo in a Gigabyte GA-G41MT-S2P LGA 775 board. It would not boot after the install. I tried flashing the board's BIOS on the MB. Then reinstalled the CPU, but still no booting up. It would spin up as I could hear and see the fans running, but that was it. Switched back to the original Intel Core 2 Dou and the PC booted perfectly. So much for my upgrade. This CPU seems to just be a non working CPU. Will try to contact seller to see what can be done.

Used this with 8GB of 1333 MHz ram and a GT 740 video card for a economy level gaming build for a friend and i gotta say its doing really well. I diffidently recommend this if you want a daily use computer or are just getting into the world of gaming PC's.

Funciono bien, ya tiene varios años que lo compre y sigue andando sin problemas. Actualmente mas que obsoleto pero lo tengo en un Servidor Plex con Linux mint con 4 GB de RAM DDR3 y una R5 240 de 1 GB.

I recently had a motherboard fail on a small server I built about 5 years ago. I wanted to re-use it to run Ubuntu and VMWare Player with a 64-bit guest OS, so I bought a new inexpensive MB that would work with my old memory and processor. Unfortunately, even though the processor was 64-bit, Intel's E64MT and VT-x technologies are required to run a 64-bit guest OS and my processor didn't support them. This was the least expensive processor that A) worked in my new LGA775 socket motherboard and B) supported these technologies. The processor works great, as does the 64-bit guest OS, and it is significantly faster than the Core 2 Duo it replaced. Very pleased.It was generically packaged with a heat-sink / cooling fan, but nothing else. There is already the silver thermal compound on the heat-sink so you don't need to buy any.

I purchased 2 of these because I run 2 pc's with these processors and thought having some spares would be nice, especially at this low cost. When they arrived they looked like they had been previously installed having a heat sink wear lines on the processor. Mine had been used a lot and were about 7 years old. I thought perhaps they might have slowed down a bit over time and decided to swap them out. I benchmarked before and after, and these were identical. Either core 2 duo's just don't die/lose speed over time or these are just as used as mine. Either way, I gave 3 stars because the price was nice and they do work.
