Re: EDP Noise Problem (overheating?)

[Tom Combs <tcombs@sep.com>]

Dylan,

A couple of days ago I finally got around to opening my EDP to reseat 
the memory sticks.  This seems to work wonders.  The EDP is currently on 
it's 3rd day of running a constant loop - no degredation that I can hear.

If you try this, please post your results.

Thanks,
Tom
