StrongARM overclocking

Posted by Richard Goodwin on 11:44, 21/1/2002 | , ,
 
Ian Hawkins, not content with bringing AcornSearch to the RISC OS community, has now published his guide to overclocking a 200Mhz StrongARM RiscPC to over 300Mhz.

Although not recommended for the faint of heart (nor, indeed, anyone else for that matter), Ian used two peltier coolers either side of his StrongARM and got it running at 325Mhz, although it was unstable above 300Mhz.

Go to Ian's explanation for details, including some cool photos.

Unregistered user Erm, isn't adding all that cooling stuff *completely* over the top, considering Castle managed to do a run of StrongARMs overclocked to 300MHz with very little cooling. Quite frankly, you shouldn't need any more than a large heatsink.

Unregistered user Castle used specially rated ARMs, though. Ian's used a "vanilla" boring 200Mhz ARM in his madness.

Unregistered user You miss the point. Being "over the top" was precisely Ian's intent. Take it for what it is - a bit of fun.

Unregistered user Hmmm.. any way of overclocking an Arm 7 to 300Mhz? :-)

Unregistered user Or at least from 40 to 60Mhz (the same percentage increase from 200 to 300Mhz)? :)

Unregistered user Oh, er, that kind of broke, so I crunched the rest of it off with some pliers. Then soldered VRAM directly to the connector. I had dodgy VRAM (dry joints on the chip legs) and after 5 hours playing about with that I eventually gave up, and removed the rest. I'm now getting a ViewFinder :-)
