OverviewCustomer ReviewSpecificationsProduct Tour
Like the superheroes of old, the AMD Phenom II streaks out of the night to lay waste to your enemies with 3.0GHz quad cores, each of which has L1 and L2 caches. An additional 6MB of L3 cache is available to handle really heavy loads or large data sets.

Memory transfers get faster than ever. HyperTransport Generation 3.0 mode allows up to 16.0GB/s of bandwidth. Up to 17.1GB/s memory bandwidth for DDR2 delivers an amazing 37GB/s of processor-to-system bandwidth. This unprecedented bandwidth is needed to feed the data hungry AMD64 with Direct Connect Architecture cores.

You'd think that all of this power would be too hot to handle. Think again. AMD's Cool'n'Quiet 3.0 technology works with CoolCore Technology to minimize heat while keeping power and efficiency up. Now the cores can shut down unused parts of the processor when not in use. This saves power and helps to reduce the amount of heat generated. This function is built in so there's no need for drivers or BIOS updates.

AMD is Back!

white Reviewed By: D Kizz on 1/8/2009
Rating + 5
Tech Level Tech Level: somewhat high - Ownership: less than 1 day
Pros: 45nm, overclocks great, makes AMD respectable again.
Cons: Read Below.
Other Thoughts: Everyone keeps trying to compare these AM2+ chip benchmark's to the i7's. That is not fair at all, you have to remember that these first batches of PII's are running on dual channel DDR2 memory, whereas most benchmarks have the i7's running on triple channel DDR3 memory. Even being behind them, these chips still produce very respectable numbers, especially when OC'd. This is AMD getting back on track.

Tech Level Tech Level: high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: Rated at a 1 so that people who are reading about all the DOA's down here will also read this. This chip will not POST if ACC is turned on in your bios (making you think the chip is DOA). Some motherboards were made before this chip and in effect have ACC on in the default bios. ACC is Advanced Clock Control. The Phenom I required ACC on the motherboard, but the Phenom II has it built onto the chip creating confusion for the motherboard. You may need to have an older model AMD socket A2 chip lying around to get your Phenom II to boot properly. So use the older chip, get into the Bios and turn ACC off. Then put in your shiny new Phenom II and watch your computer fly.
Cons: AMD really didn't publish this information in an easy to find spot, in fact I had to search for it pretty hard, especially as I bought this chip as soon as it was available on Newegg. Its frustrating to plug in a new part, and find it doesn't work at all. So all these folks who think they have a DOA, chances are good, they just have ACC on.
Other Thoughts: This chip is night and day incredibly faster than the previous Phenom I line of CPU's. Yeah, its still slower than a similarly clocked i7, but it also costs $700 less. Stable in my Asus M3A79-T Deluxe at 3.7Ghz with a big Thermaltake air cooler on it. Then consider the fact that a Core i7 motherboard costs about 3X the average Asus motherboard, and that ads up to a whole lot money you can spend elsewhere in your computer. This CPU does not disappoint, it holds its own in speed.

Pros: It worked very well.
Cons: chip and heat sink fused together. had to use a hairdryer to separate the two. once that happened fingers slipped on the heat sink compound and I bent about 40 pins. straightened them all until the last one which broke. no good!!!! only had it for three months. now I have to buy another one.
Other Thoughts: needs a better heatsink!
