Overclocking an E6600

try to find out why you can't post with a lower divider. You should be able to do 315x8 without any problem at all and if you can't there is something wrong somewhere else.

I've set mine to 413x8 to get to 3.3.
 
I second the better ram, but you only need 800Mhz to get to 1600FSB, OCuk are flogging *** OCZ stuff rather cheap, i've got it in two pcs and it's groovy **** man.
 
Update:
I have replaced my ram with 4Gb (2 x 2GB) of OCZ 800MHz Vista Gold Series. Set the timings at 5-5-5-18 with the voltage at auto

Ran Orthos and memtest @ 315MHz x 9 and it passed both. Upped the FSB to 320MHz and I'm now getting problems with random restarts. It happens either as soon as I enter my password on the Windows log-in screen, or, when I've got to my desktop and start any application. I tried upping the Chipset voltage from 1.4V to 1.5V and also upping the DRAM up to 2.0V with no improvement to the situation. I put the FSB back to 315MHz and now everthing is fine.

Any ideas would be appreciated.
 
Try dropping the multi to 8 but leave everything else the same. Then try 320x8. If it works, the original problem is with the cpu not the board. If it fails, the problem is with the board/ram not the chip.
 
What volts is your RAM rated at? If its higher than the 2.0v you currently have it set at then raised it to what is specified.

And like Mike says try the multi at 8x.

:)
 
My BIOS doesn't give me the option the reduce the multiplier. The other odd thing is that it doesn't like running the memory faster than 1:1. Even putting the RAM 5MHz faster than the FSB causes it to fail to POST. I'm fairly convinced that my mobo just isn't up to OC'ing and I'll just have to stick with the 315MHz FSB.

Ho-hum.
 
I've got the following:

Core 2 Duo E6600
Asus P5N-D2 SE motherboard
8GB OCZ PC6400 DDR2,
Asus Silent Knight Aluminium CPU Cooler..

Running 100% Prime95 4 core stable at 3.2GHz (FSB 400x9) with memory 1:1 sync, getting 13.991s for Super Pi, and ran Prime95 all last night, got up this morning and it's still chugging away...

CPU is at 1.5125v (I think in the BIOS, I'm currently at work), however, CPUZ detects this as 1.480v I think, the HT voltage is 1.46 (this is very important, I couldn't go further than 2.6GHz leaving it standard).

CPU idle in windows is 31C, fully loaded in Prime95 Torturetest is anything from 48-68 tops judging by analysis... so there we go, I thought this board was crap for the first day, then with fine tuning, it's a cracker ;-)

My C2D 6400 is stable (enough) at 1.35v in BIOS, clocked to 2.75GHz. Had no troubles playing STALKER and no errors for 30mins on Orthos. Is this a good clock at these volts, or normal?
 
What's the HT voltage/I can't find that in the BIOS. Also what BIOS revision should I use?

Just to be on the safe side, would my 500w PSU be giving me any problems?
 
I'm having difficulty working out what my Vcore actually is before I start upping it. The bios and cpu-z says it was 1.37v. So I went into the bios and switched the vcore form "Auto" to 1.375v (nearest to 1.37v). When I booted and checked CPU-Z it then read 1.42v (?). I tried to run orthos but it failed after 10mins. I'm going to try upping the vcore a notch and running orthos again until I'm stable (9x315MHz). I'm assuming (dangerous I know) that on auto the voltage increases itself under load (I have C1E and Speedstep disabled) and was actually much higher. Also, what effect would increasing the CPU Termination Voltage have? (I tried googling it and got various different answers - FSM voltage, HTT voltage, etc?????)
 
I don't have the option of the HT voltage. I have:
DRAM Voltage - currently at 2.000V
Chipset voltage - currently at 1.4V
CPU Termination voltage - currently at 1.3V
Vcore - currently at 1.365V

And I'm stuck.
