Works as expected 5/9/2017 10:08:54 AM

Pros: I bought this for gaming since games don't typically use more than 3 cores, and I can just unlock the 4th core if I happen to encounter an extra demanding game. The 4th core does unlock, but for some reason temperatures rarely show up when in Windows. The performance is fine.

I managed to undervolt it to around 1.2v at 3GHz, and it runs very cool.

Cons: Temperature sensing rarely works in Windows when 4th core is unlocked. The heatsink it came with is incredibly puny, to the point I thought it was a mistake.

Overall Review: Strangely, the CPU is classified as a Phenom II x4 B40 (i think b40?) when the 4th core is unlocked.

Free core. 8/28/2013 8:16:39 AM

Pros: I bought this to build a Windows server at home to practice with. It is not a production machine. I was able to unlock the 4th core and it has been stable for a few years now.

Cons: None. I got what I paid for plus some.

Overall Review: Running four cores 16 GB RAM and various hard drives. Rock solid for a least two years now.

Gave up the ghost after a year 12/24/2011 10:12:31 AM

Pros: Inexpensive, easily overclocked CPU.

Cons: After the first year, the processor began to crash whenever the core temp went over 40C. I sent it back to AMD for replacement.

This may be due in part to the cheap heat sink, fan, and thermal paste that comes with the unit. I purchased an aftermarket heat sink with fan and some arctic silver to do the job right when the replacement arrives.

Overall Review: I had no issues with it while it worked.

Pros: Love, love, love this processor. You see all the mess about the unlockable core. Don't buy this if you're gambling - buy it because it's a rock solid monster.

Cons: Some of those who /do/ buy it for the purpose of unlocking a fourth core will find disappointment. Mine didn't (yes, I had the right mobo and BIOS), and I was fine with that. I get 50fps in demanding current generation games. YMMV, of course.

Overall Review: The price was perfect when I bought it - under a Benjamin! Now it seems scarce and that's a shame.

Three Headed Dragon 4/8/2011 10:06:46 PM

Pros: Fast, cheap, and stable. High performance. Easy to overclock with a slight voltage change depending on ram/ hyperthreading speed. Able to unlock core, its built on the phenom deneb core without l3 cache and a 4th core.

Cons: No l3 cache. Bottlenecks at times, mainly due to no l3 which some programs utilize like video editing etc etc. Newegg no longer stocks this so go for another rana model.

Overall Review: For this price and the ability to unlock a core/ cache & being easily able to overclock makes this a champ! Runs at a good temperature with the right cooling. Been running stable overclocked @ 205mhz ht for over 8 months now. AMD does it again!
