Summary: Serious problems OC'ing this CPU. I have successfully OC'd to above 3.0 the following CPUs 2 e4300's, 1 Q6600, 1 E6750 on the same motherboard. If I adjust the memory multiplier with this CPU installed it will not boot. So I have to overclock my RAM WAY above it operating freq.
Summary: After I overclocked the CPU to 2.77ghz it seems to be a lot faster. The default speed seems to actually bottleneck the system. I'm satisfied with the CPU but I haven't really tried to maximize the overclock potential because I'm planning on upgrading the CPU within a year.
Pros: value priced, 2MB cache, dual core, overclocks well
Cons: a bit slower than i expected. upgraded from a 2400+ barton @ 2.3ghz, and default 2.2ghz seemed slower than the barton at 2.3ghz in games. This could be an issue of Vista taking more resources though.
Summary: Initially could not get this going as I had DDR2 800 memory and the motherboard was rated at 533. Thought memory would clock down. Had OCZ's but never worked. Replaced with Kingston 533 and install was easy. Fan is very quiet and easy to install with the 4 pin fasteners. Much easier than clips.
