Yer I had the early revision co wolfdale.
Yer definetely u got some potential still.

With my benchmarks and findings, memory bandwidth read and write always increased, all the way to 4.4ghz
Gaming the gains dropped off once i hit 3.8, and had little impact after that, but It was dual core, with an ancient xfx 65oi and a 4870.

Only thing to watch out for is degradation with continual high voltage.

get it to 4ghz upload some pics mate.
