I thought 3841A431 would have made into 4Ghz under 1.4, but I guess I am wrong.
This is a good result, but it blows my theory that the later the chip, the worse the OC, especially week 41.
I have witnessed bench of 3 different 3841A43x. 3841A434, 3841A436, and another one. All were duds, and one overheated severely under load. Not exactly the same batch, but close. All came from amazon.com and buynow.com (same distribution point), so I wonder if that warehouse just happened to get a bad batch of chips?
