Ive just taken the plunge into overclocking my Q6600 to get some more life out of it.

Im failing Orthos and OCCT straight away.

Ive set the DRAM Frequency to 667 Mhz. FSB to 333 Mhz and Multiplier is at 9x to give me 3.0 ghz.

Voltcore is set at 1.26 volts.

Im getting an error on Core 0. whats wrong??

Thanks guys.
 
I know this isn't of any help to you for stabilizing your o/c, but don't you need to run 1 instances of Orthos to fully load a C2Q?

Have you tried bumping Vcore up a little bit more?

Here are a couple of guides that you should check out for more info on o/cing these chips

If you search on youtube as well there should be videos on there showing you how to clock your chip, though each processor is different, and require different voltage settings to make them stable, some require less other chips need more, you just have to persevere with it until you find stable settings.

Also, you could try using LinX or IntelBurnTest for stability testing.

Hope that helps you out.
 
Hi DavyBoy. Well i decided to set all voltages back to auto to see if that improved stability and sure enough it did. High temps mind lol. So im in the process of knocking the Vcore down now. I guess i was being really optimistic with that initial Vcore. :D
 
Id find the vid of the cpu (use coretemp) with intel speedstep swithched off, as the vid display can fluctuate. Once you know what the vid is, set this as the vcore in bios and work from there, 9x333 is a good starting point as most q6600's should do 3ghz on stock volts.
 
Hi Setter yes im using the vid of 1.35 volts and it appears that OCCT is stating that the voltage is 1.31 volts and is stable at 3.0 ghz. Temps are in the mid 40's for core 0 and 1 and at 40 for core 2 and 4. Im assuming this is good. Should be able to push further I have a TRUE and 1 fan and AS5 Line Method.
 
Looks good, temps are nice and low, the difference in voltage from what youve set in bios will be caused by vdrop/vdroop. Taken from sticky in oc guide.

Vdrop
Vdrop is the difference between the selected voltage in the BIOS and the actual idle voltage, typically this is about 0.05V though new P35 boards seem to be a lot less affected by it. THIS IS NOT Vdroop

Vdroop
Vdroop is the difference between idle voltage and load voltage. The droop is actually related to the current draw of the CPU and is a peculiarity of Intel CPU design specs and as such AMD setups don't suffer from it to any great deal. Vdroop gets progressively worse as load more cores up on multicore CPUs. Some recent P35 boards now have the option in the BIOS to override the circuit in the motherboard power circuitry to pratically eliminate Vdroop. Other boards can usually have it overriden by a simple pencil mod, or with the addition of an extra resistor by soldering. 680i boards are notorious for high Vdroop with quad cores.

This is perfectly normal, asus boards feature load line calibration (LLC) which can lessen the effects of this.
 
Ahh yes ive seen LLC in my P45 asus p5q pro. I will enable it i forgot to enable it when i saw it. I remember the first time i had my board and it wouldnt POST. I called Overclockers and the said it was the LLC with quads, a simple removal and re-install of the CMOS battery fixed it. :D anyways OCCT is happily stressing it. I will deffo go further maybe 3.2 or 3.4 depending on temps as ive heard the q6600 doesnt like temps over 65 degrees.
 
With occt, p95 etc, id be happy enough with temps upto about 75c on a q6600, if temps are a concern try adding a second fan to the TRUE, gave me a drop of 5c or so when i used 2 with my last q6600.
 
I find it is easier to get my o/c stable with LLC enabled.

On my UD5, if I don't have LLC on, I get a whopping .9v of Vdroop, whereas with it enabled I only have something like .2v of Vdroop..

Some people say that LLC is bad, then others say that it isn't.. I prefer to have it enabled, as I find it tricky to get my O/C stable without it, however I am trying to get my system stable with it disabled atm, but I am having a bit of a hard time tbh..

Same here m8 i gave up not worth the effort tuened off, by the time the board suffers any if all will be time for an upgrade :D
