Re: "I often miss the obvious. Explain it to me." OK. You have to consider where Intel's next highest bin is. I expect it to be at 866MHz. Therefore a 865MHz part (at low Vcc) ain't gonna cut the mustard and will get binned out as an 800MHz. Adding just 2% for the frequency improvement at high Vcc(I made that up) would yield an 882 MHz part at high Vcc and still get binned out an an 800MHz. If you added your 12% HE guardband it could run at 988MHz and still get binned as an 800. Adding in tester guardbands for power supplies timing generators and temperature, it's not unlikely that a part that can be over overclocked to >1GHz could still be binned out as an 800MHz part. The point being that even with a much lower HE guardband, parts that are binned out at 800MHz can still run at much higher speeds and it is risky to try and guess HE guardbands by overclockability alone, which was the original point I tried to make. Sorry to tweak you the wrong way. EP
