So it was purely a video card that shouldn't have left the factory.  Rare not having to basically chisel globs of rock hard paste off inside a laptop.

 

Good show picking up on the baking trick and pulling it off without damaging anything.  When I read what you did in the software forum.  I was hoping you knew everything that had to be removed from the board before applying heat.

Radeon chip was mounted directly on the mainboard - what seems to be standard practice is to cook the whole board in an oven, at very high temperatures; but the most sane method advised low heat, for a short time. As mentioned in an earlier post here, I created a funnel to concentrate the heat from an ordinary hair dryer, so that only the area of the top of the chip was cooked; used thermocouple to monitor temperature; easy enough to slightly move the dryer away to maintain right heat level.

Even though the Kii Threes are about as good as it gets, currently, in many areas of the engineering, there is still room for improvement. Posts like the following occur fairly regularly, which says the robustness of the system is still not at a high enough level - interference factors play too great a role, still, which is something that should be addressed for optimum replay,

This is a useful post,

 

 

That is, someone who nominally rejects interference and noise effects finally had something that was so obvious in its impact that he could recognise the degradation, and was then able to sense the same behaviour in another place, even though the other listeners, supposedly fussy in their hearing, were completely unaware.

The obvious solution was invoked, get rid of the culprit. But many times one can't do that, because it may be something that you have no control over - which then means you have to step up a notch in your approach, and "harden" the system against the influences.

 

The step by step process of optimising a system simply means repeating this method over and over again - learning to recognise that the SQ is being degraded, by perhaps an extremely frustrating to determine source, or weakness in the reproduction chain, and then applying the most effective method to 'repair'. Anything less than fully convincing sound means that something hasn't been addressed enough - persistence is the most powerful tool, if one is interested in high integrity playback.

On a regular basis you see posts in threads examining possible causes for less than optimum sound - yet there is a resolute resistance to be being able to nominate characteristics in the sound that can be directly tied to these factors. That is, if the "sound is worse" then it's not kosher to admit that you can ascribe changes to, say, mains interfererence ... why? Because you can't actually "measure" it - or at least without going to a great deal of trouble - as all the best people do ... silly boy!!! :P

 

There's a marvellous concept highly useful in many fields of science and engineering - one can call it, "feedback": if you do something, and something else changes, then there's half a chance there may be some vague connection between the two ... unfortunately in audio, there's this terrifying pit ready to swallow you alive - called "expectation bias". You lose all credibility if you own up to even being slightly sent off balance at the sight of this monstrous danger - which means almost, almost nothing ever changes ... pity, that ... ;).
