I'm scared to lap my cpu?

Just today I got an AMD Phenom II X4 945 95W cpu and I am afraid to lap it before I test it. Even the tech support at XFX said that my board should be compatible, but if I lap it and it does not work I am screwed. Should you always test before you lap? The test is not bad for the chip, I mean to pound some electricity through the chip then take it out and lap the surface that you just super heated? If some one knows of a link on how to test a new cpu before lapping to make sure that any RMAs happen before you loose the warranty I would love to read it. I see oh so many links on how to lap, please no real need for that education except warnings about the test and how long to wait cleaning off initial thermal paste and the likes. What I need is the test. How can I tell that I have a fully functioning cpu before I relieve myself of a return? Obviously if it boots vista I going in the right direction. After that is it prime, OCCT, 3DMark, CPUZ, Sandra, Speedfan, Fur tests, what load, what program, how long, should I shutdown and restart, cool then heat, OC or underclock for stability? I know there are some who have made many systems for enthusiast and I would love some advice.

Update:

Lapping is when you flatten the CPU and heat sink by sanding it down. I already have built the current system and know everything that is necessary to install a cpu, but sometimes when you install the chip it just doesn't work DOA is what they call it go to newegg and read the reviews on any of the new processors. If that where the case and i had sanded it they would blame the sanding not the faulty cpu.

    Lap it?

    I have never heard of that.

    You are talking gibberish.

    Why not just install it in accordance with the manufacturer's instructions?

    Its a mad idea I know - but maybe give it a try....

    EDIT: what is the point of "lapping".

    The top of the CPU is engineered to be very flat and so is the heat sink. Any microsocopic differences are smoothed out by the heat transfer paste. That's what its for - no?

    Even if there was some tiny % of advantage in lapping, surely you could run it enough to know it was not DOA without needing to lap it.

    once you set it on the socket they won take it back, now this is not a car and all chips are burned in at the factory meaning tested if you trust your vendor and know the way the chip should be inserted then go on with it make sure you ground your self don't use much heat transfer grease set your heat sink, fan and you are good to go
