Summary: Great processor for the money. I love to overclock and I lapped this CPU, put a good cooler on it, and overclocked it to over 100%. Ran it at 3.2GHz 24/7 on a T-power i45 board with corsair memory. Suicide runs on chilled water were 3.5GHz. While this is a lower end CPU if you have a 775 computer with a P4 or celeron. This would be a great little chi to improve performance having 2 cores, more cache, and newer technology.
Summary: Performs great for an older 1MB cache dual core CPU. I overclocked it to 2.60GHz without any additional voltage. Using a Radeon 4670 and a 70% efficient PSU, full CPU+GPU load is only 165 watts from the wall. I used the larger-sized Intel heatsink (not the half-height one) and under gaming load the CPU peaks at ~62°C with only two intake fans -- one in back, one in front.
Summary: From 1.6GHz to 3.2GHz no problems. That's a 100% overclock. 30c idle, 50c load, very cool. E6850 is selling for $275 and this $70 CPU will outperform it when OC'd. It is a Core 2 Duo Conroe chip. Enjoy.
Summary: This CPU is absolutely amazing. I installed it fairly easily into a MSI 650i based motherboard. Idle temperatures where under 30C when checked in the BIOS. I was able to easily over clock it to 2.66GHZ, a 66% over clock, by simply boosting the FSB to 1333, no voltage changes needed, on stock cooling. I'm sure I could hit 3GHZ if i wanted to mess with voltages and RAM timings.
Summary: Highly Overclockable, I could overclock to at least 3ghz if my ram wasn't so bad. Currently have it overclocked to 2ghz and it runs at 29c idle with a flat, even layer of Arctic Silver 5 across the top. I'm going to pair it with 2gb of Corsair XMS2 (probably need 4gb of overclockers ram for higher results) and a Radeon HD 4850 for awesome gaming!
