If the supplier wants to make that sort of claim, then that's fine as long as the replace any cpu's that don't do what they claim. I'm honestly surprised this even happens.
At OcUK, they do a '4ghz 920 D0' bundle in which the CPU is pre-clocked on a board to 4ghz, so, if you sent a chip back that would do 4ghz but it had a problem, its fair to expect a similar bin in return

Just picked up my EX58-UD5 and been playing around with it a little. I was wondering if anyone could help me out with a small problem. I have a I7 920 Batch #3845B026 which can boot into windows at 4Gz with 1.18-1.20V. However, I am having trouble figuring out the voltages on this bios (F8). I set the CPU Vcore to 1.25 in the BIOS but in CPU-z I see 1.18 - 1.2 but hardly ever over. Is there a bios setting to make the chip take the voltage set in the Bios?
Have you enabled 'Load Line Calibration' in the BIOS??
Basically all you are experiencing is vdroop which is pretty normal, enabling LLC helps to surpress it a little, but as long as your system is stable, I woulnt worry too much
