E6600 @ 3.4ghz stable, but worried about the vcore

[Gundogan]

Hi,

After some overclocking I kinda hit a wall on 3.4ghz. But this was my target clock anyway, so I'm happy. I did however need a 1.5125v vcore in bios (1.46v in speedfan/cpu-z) to get this, rest of the voltages on default. Is this safe to run 24/7 with this amount of voltage, or should I back down to 3.2-3.3ghz with a lower vcore? Or is there some trick I'm missing :<
My temps are 27-30C idle and 50C load (TAT and coretemp give 46-48C load, speedfan 50-52 and in bios its 30ish I think).

My systems specs are:

E6600 (week 29B) + tuniq tower 120 with a silverstone FM121 fan
P5B deluxe wifi/ap
2gb of corsair XMS2 PC6400 ram (5-5-5-12 timings)
OCZ gameXstream 600w
7900GTO 512mb
Thermaltake Soprano case with silverstone FM121 fans (1 intake and 1 outtake).

should I back down to 3.2-3.3ghz with a lower vcore?

Yes, I would. You don't need any extra power if it requires anything more than default voltages.
I'm sure this CPU is nasty-fast at ~3.0GHz speed... and much cooler too.

3.2ghz req 1.34v vcore and doesnt go over 40C. Alot safer I guess

Well, heat is the enemy :twisted:
And you are not suffering from a lack of performance there...

The p5b deluxe is notorious for its vdroop.
The bios set voltage is more than the output voltage.
.5 to .6 volts droop is normal for this board even though it’s not the norm for other cd2 motherboards.
Some say its poor bios writing others say it’s a flaw in the sense circuitry that controls the output duty cycle of the pulse width modulation driver stage.
Thus we have Vdroop before load. (That’s another subject)
If your temps are in line and your still around 1.4 to 1.44 volts reported in windows your fine.
If your not comfortable with the idea then by all means reduce the vcore in bios
3 GHz on the E6600 is more than enough for your needs.
