Great, just be careful with your BIOS upgrade.

Reviewed in the United States on May 2, 2015

Verified Purchase

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.

EXTREMELY easy to install

Reviewed in the United States on November 7, 2014

Verified Purchase

WHOA. EXTREMELY easy to install. I replaced the Celeron cpu that came with a Dell PC back in '05, '06 no later than '07 (I don't remember exactly. Buying the PC @ the time w/ the Celeron saved me a TON as these were JUST being released, so to buy the exact same pc w/ THIS processor intead of the Celeron would have cost substantially more. Well, fast forward to 2014, I pulled the Celeron, cleaned the heat sink and fan good from accumulated dust that didn't get removed during previous gen. maintenance put this baby in it, removed the old, hardened thermal goop; applied the new goop, sealed it up...if it took an hour that was a stretch. My old Vostro 200? It is f*cking screaming using Win 7. The real test was Firefox for one, then Internet Explorer 11. Ho-lee sh*t what a difference. It's performing better than a newer Dell Inspiron Desktop/Tower I got maybe 2 years ago w/ i5 processor; 64 bit Win 7 w/ 8 GB RAM, I'm serious. The pc I put this cpu in is running 32 bit Win 7, 4 GB RAM, In-f*cking-credible. I am SO freakin' pleased with this you wouldn't believe it. "I" can't believe it. In case it didn't occur to you (Hey, it happens right?) I have no complaints about my purcchase. WOW. Very happy. Very, very happy. 20 bucks? REALLY? Whew. Wow. Yeow. Icn't say enough good things. Sluggish, too frequently misbehaving IE??? Marked improvement. Freezing up too often and making me wait impatiently, often crashing Firefox??? Even MORE markedly improved performance. Did I mention I like this and I'm in a pretty good mood about the whole deal and she-bang? Sheeeeeeeeeeeeeeee-it.

Reviewed in the United States on March 11, 2017

Verified Purchase

We are still using 2 LGA775 motherboards with Pentium processors. The E8400 is one of the most capable or the LGA775 processors. We are thrilled to upgrade our boards with such a capable processor at such a modest price. We are moving from processors with 800mhz FSB and 2MB cache to 1333 FSB and 6MB cache. That improvement ought to be worthwhile.

Individuals interested in this product probably know, but it does not hurt to repeat, you motherboard must have an LGA775 socket, and the bios has to support the E8400. You can verify that at the motherboard manufactures web side under CPU support. If your bios does not support the E8400, you may be able to upgrade the bios to a version that does by flashing.

Works great, easy install, nice upgrade for a great price!

Reviewed in the United States on January 8, 2015

Verified Purchase

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.

Reviewed in the United States on December 30, 2016

Verified Purchase

The CPU arrived in a static proof bag, wrapped in bubble wrap. I expected it to be in some sort of CPU holder or case but it doesn't affect my overall rating. The CPU fit into the socket as it should and driver installation was very quick and worked flawlessly. I had no trouble getting this product to work.

BEWARe!! Does NOT work!

Reviewed in the United States on October 23, 2013

Verified Purchase

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.

Very fast shipping; amazing amount of care and attention given to the shipped package

Reviewed in the United States on October 19, 2012

Verified Purchase

I ordered this on Wed and did not expect to receive it until the second half of next week. But I just received it, right before the weekend. The shipping is extremely fast. I buy online a lot and I never have this kind of very fast shipping unless I have to pay a lot of shipping cost.

When I opened the package, I could see that the seller put in a lot of care and attention. Besides the CPU (it's a Core 2 Duo E8400 which I absolutely love), there are items that I did not expect to receive: a tube of thermal paste and anti-static wrist strap. Even the CPU retail box from Intel (when I bought the i7-960) does not include such items. The anti-static wrist strap is especially useful for me since I spend a lot of time tweaking my computer systems.

And I also have to mention that the price is really really good for a brand-new CPU of this type.

I definitely will buy from Digiconcepts again. Thanks for the amazing service that you provide!

Item was well packaged and protected. CPU works fine so far. Great value.
Personally I didn't notice any difference in performance from the E6750 2.66Ghz which it replaced. But then again I don't have benchmarking S/W.

Exactly what I desired, the product arrived in expected and described condition, and works flawlessly.

Formerly my machine (Dell Optiplex 755 MT) had a CPU without VT-x capability!

Which stopped me from booting virtual machines, a pet hate, and now with this CPU am good to go.
