I gots nearly the same E8400:

FPO/BATCH# Q740A555T
Version# E27439-001

I wonder if anybody has a Q739 or earlier, or is Q740 the first run? I normally shop at NCIX, but I got mine last Sat. for $20 cheaper. A-Power exchanged my first E8400 with wonky temp readings for a new one from the exact same batch. Fortunately this one reads 38/36C at idle (4.05 GHz) and about 50C in Prime95.
Bios:
vCore: 1.35v
vDimm: 2.0v
FSB Term: 1.2v
CPU PLL: 1.4v
NorthB: 1.25v

All other voltages on Auto at 450FSB. I had it up to 4.45GHz with no problems, but requires too much voltage and heat for everyday use. Here is my 24/7 setup which is stable and cool. I wonder why my latencies are so slow compared to some others? I've tried upping freq. to over 1300MHz, but still 52ns is best it can do?
