In the ceramic
There's no reason why the FX-53 should look any different to the incumbent CPU. It uses the same ceramic packaging and identification. All we can gather from the codes is the date of manufacture; Week 01 of 2004. That makes it a comparatively old CPU. AMD's been able to hike up the speed without having to resort to an increase in core voltage, which remains at 1.5v.
The last of the 940-pin FXs?. Seems that way. AMD wants to reserve the socket for Opteron use alone. The integrated heatspreader makes installation a real cinch. Simply place it into any compliant motherboard (nForce Pro 150 / VIA K8T800), use an Intel-like retention mechanism, and secure the cooler on top. Saves having to fret about with bare cores and badly designed locking mechanisms.
We've covered the basic specifications in the table on the previous page. AMD's literature offers just a touch more information.

And here's how CPU-Z sees it.
Our sample was a CG revision which is reckoned to have better general compatibility with high-speed DRAM modules. It's also able to operate with a 2T DRAM command. Interestingly, both C0 and CG steppings are present for the Athlon 64 Model 3400+ CPU (Clawhammer). Tweaking the memory controller has paid dividends.
About as tight as the memory's latencies would go. Wouldn't it be nice to have some 2-2-2-5 Registered DDR400 memory. We'll put a request into Corsair and OCZ.
