intel Core i7-3770 Quad-Core Processor 3.4 GHz 4 Core LGA 1155 - BX80637I73770 (Renewed)

i7-3770 (NOT i7-3770K!) Works perfect for what I bought it for, a Dell Inspiron 660 that had an i3 in it. Chipset and BIOS update would allow it to take double the amount of ram Dell said it could, and also allows for this CPU to double it's speed. Has onboard graphics, although I wanted the Xeon version, but this one was available without ordering from Chyna. Double the price, but worth it. If running this type of upgrade, replace stock CPU cooler, if it hasn't been done already, this will generate a little more heat and you'll avoid the thermal tax. Runs around 35C at idle, 55C under a full stress test, well under it's thermal throttle threshold with a new CPU cooler.

Shipped in quality packaging. Clean item, zero issues. Nearly an instant upgrade upon arrival. Performs as expected.

This CPU worked great from the start. Slight glitch in the installation being I was replacing an AMD board with a Gigabyte express board, so I got a "bios is corrupt and needed to install from a backup. It figured it out on its own, and continued with the install. Lot's of updates as the computer hadn't run in a couple of years, and I am running with just 4GB of ram, but I'm happy to have my old programs back and it was a cheap fix. Hope this helps.

Good product

The CPU was a "pre-owned" unit. The small plastic holder, the same as the one found in the original packaging, had opened during transit and as a result, the CPU had been bouncing around inside the packaging. Thankfully, this CPU does not have pins to bend on the bottom and was able to be installed. It ran fine. My only complaint is the packaging, which is why 4 stars not 5. A little Scotch tape around the plastic holder would have been all it took to keep it closed and better protected.

The product worked really well

I have a desktop computer that I built myself using an ASUS P8Z77-VLX motherboard. That motherboard is 12 years old. However, I still like this computer. I had previously upgraded it to Windows 10 and to the maximum 32 GB of RAM and wanted to know what else I could do to prolong the life of this PC. While browsing Amazon, I came across an Intel Core i7-3770 Quad-Core Processor 3.4 GHz 4 Core LGA 1155 - BX80637I73770 (Renewed). After doing a little research, I concluded that this CPU was compatible with the motherboard on my PC. Furthermore, given that it was renewed, the price was very reasonable. Given the inexpensive price, I had nothing to lose by trying this CPU and everything to gain. I am not a PC expert, just someone who experiments from time to time. That's what I did when I built this PC. It has served me well and is still performing. I like to work with many windows open, so I have surround display, using multiple monitors. Over time, leaving many windows open tends to cause a drag on the computer. Upgrading to the maximum RAM helped, but I wanted as much speed and capacity as possible. A brief search on YouTube provided me with an instruction video on how to install the CPU. It required removing the CPU cooler, changing out the CPU, and reconnecting the CPU cooler. The whole process took about 10 minutes. Since upgrading from the previous i5 CPU to this i7 CPU, I have noticed a significant difference in PC performance. The upgrade cost me about $60 because the CPU was refurbished or Amazon Renewed. Lastly, upgrading from the i5 CPU to the i7 CPU did not require a Bios upgrade because the computer was already running the most up-to-date version of the Bios. So, if you've got an old PC like I have, and you want to continue using it for a while, it's worth upgrading the processor, especially if you can find an Amazon-renewed version available. For a small investment, you can get better performance and give new life to your old PC. I definitely recommend it.

I received the item and it was packaged well and in great shape. I had to return do to a issue on my part. I ordered the wrong socket type. I'm sure it was fully functioning and was as described of I had the chance to use it. Would order from them again.
