What customers say about "Details"

AMD Phenom II X4 840 CPU Processor

This CPU installed without much of any trouble. I recommend it to everyone.
Since it's AM3, you can use it in AM2+ motherboards as well. Cool processor.
Easy installation, and immediately recognized by my motherboard.
This was very easy to install into my motherboard, I booted up and right away I saw all four cores running.
Really convenient and easy to install, good AM3 socket.

AMD FX-6300 CPU Processor

Good performance with fast memory. Good price as well.
The Phenom II 965 had a weaker memory controller than this FX series processor, I am very pleased to see my options increased for overclocking my ram if I so choose.
Bought this as part of a gift (built a media center pc) and it is quite fast and perhaps overkill of HD but not so much for 4k content (have yet to try it since I don't have a 4K display yet).
I tried using the Turbo boost, and only got to 3.7ghz with a aftermarket cooler, and the CPU will have cache faults frequently.
Thats not good at all, in fact the CPU started slowing itself down to prevent damage. This means I was actually getting a SLOWER processer than I paid for.

What customers say about "Technical Specifications"

AMD Phenom II X4 840 CPU Processor

This CPU seemed like a perfect improvement for a solid price. And it sure was! Nice and fast.
All I wanted was a fast machine and I built one. The CPU does a great job.
Very fast for an earlier model CPU, very capable to run most software and streaming needs.
This is a good product fast and reliable and of excellent quality.
Good processor. It's more than fast enough for office work applications.

AMD FX-6300 CPU Processor

The AMD FX-6300 is an excellent CPU. Being a six core, it already has an advantage over the more standard quad-core options.
Upgraded my mothers Desktop PC from an old Pre-Built HP (quad-core) to this FX-6300 - 6-core and what a difference. Even though these processors are an older generation, they still kick out a very very good performance for the price.
It certainly is an old chip at this point, but the price to performance is still one of the best.
It has been stress tested for the past 5 minutes. No crashes and the temperature seems stable at 39 degress celcius. The CPU is overclocked using the OC Genie of the MSI Motherboard.
The only thing that should have been improved is the stock cooler. The temperature on this CPU measures at around 66°C at full load, which to me, is not really acceptable.

What customers say about "Cache And Memory Specifications"

AMD Phenom II X4 840 CPU Processor

CPU works great with 8 GB of RAM and a Patriot SSD.
While it has no L3 Cache, it does come stock at 3.2ghz, which alone makes this a great deal.
This is a great little processor. No L3 cache. It shows a bit, but not enough to make it important.
There is no L3 Cache, but at 3.2 Ghz, it doesn't seem to make a difference.
The L3 cache missing is noticeable, still wanted it to be.

AMD FX-6300 CPU Processor

Good performance with fast memory. Good price as well.
This is a great processor if you are doing multiple things at once on your computer, remember to check the memory you have or what you will put in there because is slower then normal.
This cpu is good for everything and if you combine with an AMD graphic and 8gb of ddr3 memory ram gonna be one of the faster pc on your neighborhood !!!
It's clocked at 1.2V and a clock speed of 3.5gh right our of the box. It has 8mb of cache. Recommend to anyone for there first build. Cheap with 6 cores and 3.5gh for 100 dollars nothing can beat it..
