AMD Athlon 64 X2 Dual-core 6400+ 3.20GHz Processor

Top-of-the-Line x2 Processor

Strengths: Great item highly sought after.

Weakness: NO Fan Heatsink

I would highly recommend this CPU to anyone that is looking to get the most out of a dual core AMD CPU. It tests out to be about 7% faster than the x2 6000+ however it costs more money than the 6000+. You will also have to purchase a good Heatsink/Fan for this beast but in my opinion it will be well worth it. If it would have come with a Heatsink and Fan I believe this review would have been a 10

Back in Black!

Strengths: Extreme Speed, Fastest AM2 Processor Available!

Weakness: No fan, extreme heat and power consumption.

Well, AMD decided to try making their first special edition processor. For water cooled cases this processor is the most extreme AM2 you can buy for now until the Phenom processors come out. Extremely fast, but it does consume a ton of power and produces tons of heat.

HOT buy, literally!

Strengths: 3.2 ghz, dual core, 2mb L2 cache

Weakness: extremely hot, not too well on over clocking as some models

I bought this processor to replace my amd athlon x2 5200+ processor. I had my 5200 overclocked from 2.6 to 3.04g so i figured i could clock this one pretty high too. As soon as i put this sucker in (used a stock amd cooler which i had from my 5200, i used a zalman one on my 5200) this thing was too hot to operate. Even in just windows vista not overclocked it as running around 50 something...

Even in just windows vista not overclocked it as running around 50 something degrees C. Put the Zalman fan on it and it still is too hot to play games, had to order a thermoelectric cooler. So far ive only been able to overclock this one to 3.4ghz. my 5200 goes 400mhz over this one only 200mhz. Also windows vista does not recognize this processor, must be too new. Was thinking i should have gotten a 6000+ instead, but im happy with it (it IS the fastest)

Good cpu for the money

Strengths: Value for performance. Unlocked.

Weakness: None so far.

Didn't come with a heatsink and fan. Just as well anyway as I got the cooler master hyper 2 x cooler to slap on it free after rebate. Not running it overclocked. No problems so far. Runs smooth, stable and cool with good performance. Installed easily on my gigabyte GA-M59SLI-S5.

One fast CPU

Strengths: Fast. Fast. Fast.

Weakness: Hot. Hot. Hot.

I began building and overclocking my own PCs back in the 486 days. Somewhere along the way I got married, had kids, and found I had no more time for endless tinkering with PCs. One day, I took the big plunge -- I bought a stock PC from a major manufacturer.

I began building and overclocking my own PCs back in the 486 days. Somewhere along the way I got married, had kids, and found I had no more time for endless tinkering with PCs. One day, I took the big plunge -- I bought a stock PC from a major manufacturer.

I've been running with that stock PC for a while now, but I had an urge to tinker again and managed to convince my wife it'd benefit her, too, since she was thinking the old PC was slow.

I found what seemed like a great deal on the 6400+ (about $150 shipped), and I jumped on it. I picked up a well reviewed AM2 mainboard to go with it, some of the readily available and inexpensive RAM, a generic Athlon 64 X2 heatsink/fan, and went to work.

Getting it up and running was pretty easy -- I guess it's like riding a bike. I was duly impressed by the speed and couldn't wait to see how it overclocked. Houston, we've had a problem. I thought the CPU temp seemed high under normal operation, but I wasn't sure how hot these things were supposed to run. Just overclocking a little, though, apparently pushed the temp beyond the stability point -- BSODs and reboots ensued.

This certainly is one fast CPU, and given what I paid for it, I feel good about the purchase. I would like to see what's state of the art in cooling solutions today and see if I can get this thing to overclock; buying a CPU and running it at its specified speed almost seems wasteful.
