Pros: Cheap, Cool, Fast, Mild OC's

Cons: Locked Multiplier, No L3 Cache

Introduction:

I think this is one of AMD's great cheap processors. That fact that it is a quad-core for such a low price is incredible. It also runs really cool, and does have a small amount of OC potential.

Review:

I only use my system for gaming, paired with 6GB of 1500mhz ram and a HD 6950 and I can max out almost all games like Skyrim, BFBC2 and MW3. I did need to OC it to 3.6ghz to solve my GPU bottleneck though.

I was easily able to OC it to 3.7ghz on my Cooler Master V6GT on 1.35Vcore. If I jumped it to 1.4-1.45 I could probably get 3.8 outta this thing, but I don't want to risk frying it.

Conclusion:


All in all it is a great chip for a budget gamer, and performs extremely well.

Pros: runs very cool and has decent stock clock. With proper Board and cooling it overclocks awesome! (got mine to 4.3G's)

Cons: of course no L3 cache but knew before purchase.

Stock speed is 3.2Ghz which is pretty decent for 45nm Propus core. Has a TDP of 95 Watts and runs really cool, no suprise. I had my doubts and took a gamble (not much at $90 Bucks). I installed the chip in my ASRock 990fx Am3+ board with a H100 cpu water cooler and it ran like a charm. I wanted to get the most for my money so I researched ALOT on OCN and other sites about how to overclock. I ran into minor problems but managed to get to higher and higher frequencies. When I got to 4 Ghz at 1.3875 Vcore I was pretty satisfied. Temps were only 50c 3 hours of blend testing in Prime95. After more reading I discovered I had roughly 18c more I could go before I needed to start worrying I was gonna fry the chip. I tried to go to 4.1 Ghz and hit a wall in the voltages. I needed 1.45 volts to get to 4.1 than 1.46 for 4.2 and than another big jump to 1.5 for 4.3ghz where I stopped at for my 24/7. I just couldnt imagine it could take anymore than this. I am VERY satisfied with this little budget quadcore and By overclocking it 1.1ghz over stock frequencies I think I got my money's worth. Cpu nb is at 1.35V (2710Mhz) and HT is at 1.2v (2180mhz)

I would highly recommend this processor to anyone as it does everything I ask it do to and extremely quickly and efficiently. Can it keep up with a 980? Heck no but its also 2/3 cheaper for maybe 20% less performance. I like that ratio. If you have any questions about the 840 just PM me and I will reply asap. I have had 2 of these chips now (sold one) and have yet to see a 24/7 overclock of this cpu higher than mine. Thanks for reading hope that it helped your decision!
