Core2Duo E4300 Overclock

[Martorial]

Proc: Core2Duo E4300
MotherBoard: E-ASUS P5N SLI
Videocard: Ati X1950 PRO
Memory: 2 Memory 1 GB Umax
2 Memory GEIL 1GB
Power: Antec 450W
Carcasa Antec, 3 fan (2 in front, one in back)

Cooler: Scythe ANDY

So I gave the FSB in 1333 and is 3 GB. Seems stable in Asus Probe lying at 36 degrees in idle and load goes up to 48. The problem is voltage: the auto and left stands 1.44. I tried to give it 1.35 but then it do not enter windows.

What should be the voltage for that? Will this affect the proc?

What do you recommend?

[SUpER CoP]

Pretty much if you know 1.44 open nonstop. A E4300 usually goes to 3GHz with 1.35v without problems, the first models went even with default voltage.

And why not want to get in with 1.35 windows? Just something very interesting: When try the full load voltage, drops to 1.38 ?

Another thing: I have two temperatures in Everest. In load: CPU: 47 degrees; Core: 80 degrees

Idle: CPU: 34; Core: 48

The next instant the temperature drops after orthos stop, the other decreases gradually.

Why so big difference between the two temperatures?

[SUpER CoP]

The Core is important. Now, take following points:

1. Dropping the voltage from what is set in BIOS is called VDrop. In general you have a voltage less than that set in the BIOS in idle, and the load will drop even more. And to me the difference is between the terms set in the BIOS and what you see in 0.06V load is on a similar chipset: 680i SLI.

2. Temperature of 80C seems very high. To me, Q6600 B3 at 3266MHz does not pass in 68-69C load with prime95 blend / large FFTs. The Linpack reach 80, but I was not curious to let that temperature to see how stable.

3. 1.44 V is in truth a lot, with all VDrop. From my experience with the 680i, and sometimes a little more power than the SPP and MCP sometimes lead to stability. You can try this course in small steps and carefully monitoring temperatures.

4. May you play a little at FSB. I noticed differences and 1MHz can make the difference between a perfectly usable one that is stuck / restart.

5. See voltage and FSB, I get the best results with 1.3V, less than that system is not stable at all in Overclock and moreover, it will not bring any benefit.

Someone told me to get cooler, to clean processor paste and apply another layer.

I had little trouble setting the cooler on board. Pressed too hard to catch and I was afraid to break board. After I found a good position and not be undone.

It could be that?

[SUpER CoP]

Yes, high temperature may be a consequence of that is not fixing the cooler or how the thermal paste is applied.
