5 out of 5 eggsGood Multitasker CPU - Over Clocks 10%

Pros: Bought this socket AM2 CPU off of a friend for $10 used to stuff into my old gaming system with Biostar MCP6PB M2+ motherboard, when I removed the Athlon II x4 620 AM3 to stuff into my newest gaming system with Socket AM3+ socket and 8GB RAM. This CPU came out of a Business Class HP and it benchmarks better than the more common AMD Athlon x2 4450E due to a difference in the Cache configuration. This CPU runs so well in my old gaming system that out of habit I actually have been using my old gaming system more than my new system. Playing Games like World of Warcraft 5.4.8 with Windows 7 64-bit and 4GB of Corsair DDR2-800Mhz XMS2 with AMD ATI Radeon HD 5450 video card with 512MB Video Memory on normal mid-range graphics settings the dual-core is fluctuating evenly between both cores of 60 and 80% utilization with no game lag and 30 to 100 fps depending on where in the game I am at and what is going on. This CPU also runs fine with a 10% overclock. I am running it with stock cooler at 2.53Ghz by increasing the FSB from 200Mhz to 220Mhz. The fastest I got it to run was 2564 Mhz, but the graphics card started to show surging and fps fluctuations at 223Mhz, I started backing off on the OC and at 222Mhz everything worked ok, but the CPU temp was running around 57C on stock cooler. At 220Mhz for CPU clock of 2530Mhz with locked 11.5x multiplier it idles at 37C and tops off at 53C. Without overclocking it the idle temp is 30C and 45C loaded at 100% load using y-cruncher etc

Cons: None

Other Thoughts: I wish I had a second one of these CPU's. In addition to gaming with it with no problems for World of Warcraft, Skyrim, Aion, Blades of Time, Diablo 3, and other games I play, I also record game events with Fraps and use Virtual Dub 64-bit to take 30GB video files and encode them to 1GB AVI files to share on youtube. I have been able to encode 8 video files at the same time using Virtual Dub 64-bit. At 1 video converted the cores show 60% usage, and at 2 videos converted at the same time its in the 90%, and for 3 to 8 files at the same time both cores are solidly pegged at 100%. The most I have processed at the same time are 8 video files, but at 8 files encoded from RAW Fraps format to AVI at the same time you start to see that its starting to bring the CPU to its knees with essentially 4 video processing encodings per core. You start to see that the Windows 7 Gadget clock only shows a change in the second hand about once every 3 or 4 seconds vs every second as a normal clock would. *** This is one powerful dual-core for multitasking and I now know why HP chose it for their AMD CPU Business Class Desktop product line *** Also with the 10% overclock at 2530Mhz it chugs through the video encoding conversions without any flaws in the end product videos and gets them completed almost 10% sooner.

4 out of 5 eggsSmigglepigundis!

Pros: Feels snappy, stays cool (I think, bad temp sensors are a known defect of the brisbane core),low tdp and oc's like a champ, have mine @ 11.5x250 HT 4x 1.375 vcore for 2.875 Ghz in a Gigabyte MA-770 UD3 rev. 1 BIOS F3.

Cons: One egg for temp sensor not functioning. This is the best of the 65nm tech IMHO because of it's heat output and power consumption. Obviously features the same specs from the 65w...which don't look so hot at first and are proved unimportant upon observing real-world functionality.

Other Thoughts: Good budget core. Why is it so much? Mines was 40 dollas free shipping, OEM version.

5 out of 5 eggsFast and cool

Pros: Speedy, afforable, low-wattage, large L2 cache

Cons: Heatsink and fan are adequate but in the down position the "cam" on the latch interferes slightly against the socket on my motherboard when going to the locked position so it took a few tries to get it set.

5 out of 5 eggsGreat and effecient

Pros: Low wattage core, runs cool. Is quite fast enough for lots of things including some decent gaming. Makes my laptop Turion 64 single core seem yesterdayish

Cons: Came in a bit unprotected for a CPU in the packaging, but no bent pins

Other Thoughts: I actually have the AMD Athlon X2 BE-2400 which is the same exact thing as this processor, just a new name from 2007. I run an EVGA 590SLi board with 2GB Crucial DDR2, Nvidia 7300LE(for now) and single 80GB hard drive(for now). The only other processor I would consider is the X2 6000+ just for more speed but I have yet to max out my current processor..Would buy from Newegg again!
