Pacha, thanks for posting your results - they look pretty much in line with the L804A I tested earlier. I, too, could hardly stabilize it at 3.4GHz with 1.425v in BIOS (+ load line calibration enabled).

So when all 4 cores are fully loaded do you notice any major difference among their top temperatures? Mine showed about 2 - 3 C at most (@3.4GHz load), even though at idle the T difference was greater than that (don't know exactly why). If you see big gap in core temps you probably want to re-seat the heatsink. Otherwise it means the seating is already optimized.

And after you've done pursuing the top end, try to find the minimal Vcore that stabilizes the highest clock speed before the "Vcore big jump" kicks in. That would be the point where the CPU runs in the most efficient way (in terms of performance/watt). In my case, I found ~2.8GHz is that speed for the L804A. With a mere 1.175v the hottest core barely hits 47C while other cores < 45C, air-cooled. My guess is that better CPUs will have superior clock/voltage ratios for that point, which could be used as an index to illustrate a CPU's potential. Honestly, I'd use that optimal point as my 24/7 settings.
