OC TRIAL #3

FSB 400 x 9.5 = 3.8ghz @ 1.296v (BIOS)
Run Time on Linx: 28m 34s

Main Components in Rig:
E7400 3.8Ghz @ 1.280v, with AC Freezer Xtreme
Asus P5QL-PRO
2G Kingston HyperX 800mhz
FSP Epsilon 80Plus 600W

Report:
I have decrease the Vcore to the point of minimum voltages that the E7400 can handle @ 3.8Ghz:
1.280v. in CPU-Z; 1.296v in BIOS, which is about just one increment away compared with my previous 'OC TRIAL #2' @ 1.3v BIOS

The Vcore hovers around 1.28v to 1.292v in CPU-Z during the 20 rounds of LinX test runs.
I'm really stocked with the maximum temperature readings by only reaching @72c this time, 
probably due to the lower voltage than my previously OC TRIALs, and not to forgot, the good work of the AC Freezer Xtreme. 
On average the temps are approximately around 60c~65c on the LinX test runs.

I will humbly accept this OC setup because this is my main rig and I intend to run it 6hours+ average, per day.
Therefore I will stick to this setup, for now.

    Talking about 4Ghz as benchmarking, I still could not ascertain any stability within those Ghz range. My hypothesis is that due to motherboard lacking the capability to OC 400 X 10. So in the next benchmarking test, I will try varieties of FSB X multiplier combinations to attain the 4Ghz mark, or at least the closest as possible.
I probably need a P45 chipset motherboard to OC seriously. But then again like I mentioned, I'm fine with 3.8ghz system for daily usage........
