Nope, but they were pretty close. The C0 8400 had VID = 1.225v while current E0 8500's VID is 1.25v

unclewebb: Thanx for the link. I see your point. But first of all we're talking about temperatures at load around 70C (whichever Tjmax they used, this is much above the 50C, so no "slope error" here, right?).
And then if we assume their measurements are correct, -9W actually seems not that small difference, and it resulted not in -1C but in +2C according to their testing, which is what confuses me most.

That C0 is not mine anymore but I might ask to play with it a little more. Problem is, this 8500 E0 has both sensors stuck at anything lower than 36C, so no clue how'd I calibrate it. But right above those 36C both sensors show same temperatures. The C0 8400 (calibrated) would heat up to ~70C under Linpack at 4.16GHz @ 1.400v (CPU-Z under load), the current E0 8500 heats up to ~73C at 4.3GHz @ 1.344v (CPU-Z again). I must admit I'm a little afraid pushing 1.400v through this one given the current temps, and thus can't set the E0 to same clocks & volts as C0.
