Concerns over my overclock on (QX6850)

[Aznguy1872]

So I started Ocin my QX6850 running on air. I am trying to get 3.33 Ghz stable on it, I have the voltage in bios set at 1.41 (everything below that I've tried has failed ORTHOS). Now when I open up cpu-z it says my voltage is at like 1.216 now isn't that alittle too low? My guru program from Abit tells me its at 1.36 voltage. So I'm alittle confused which to follow. Also is hitting 57 degrees at load with PWM at 70 degrees ok temps? Anyway, please help me get this chip stable at 3.33 Ghz.

Heres a pic of whats going on.

uguru account for Vdroop. The voltage you set in the bios always drops down some when you get into windows, especially under load. CPU-Z almost never gives proper voltages in my experience. Your temp is ok.

You may need more voltage than you're giving it in order to get stability.

Also make sure your memory is not running at a speed and at timings it can't handle. Set the proper voltage as well. This is the most overlooked part of overclocking for many people.

Oh ok, I'm starting to think if its worth it to Overclock this any higher then 3.2 Ghz. At 3.2 Ghz I dont have to mess with any voltage settings at all. adding more voltage so far has gotten me to 3.3 Ghz, which isn't really worth it I guess, if it fails Orthos I will just drop it back down to 3.2 Ghz.

To get 3.4Ghz you may need 1.45v (roughly 1.4v after droop) It all depends on your luck.

Thanks for the fast replies. So that 1.45 should be the max voltage I should be putting on this processor then i suppose? I guess I could handle that. Just want to make sure I don't break this chip as I plan to use it for a very long time.

UPDATE: So its at 10 mins ORTHOS now, a CPU being stable should be able to run it for about 6 hours right?

A few hours Orthos = more stress on your CPU than any game, benchmark, or other application will ever do.

I don't have a recommendation on safe limits. I'd say 1.45v actual (somewhere around 1.5v in BIOS) is where I'd limit it to depending on how much heat it starts putting out.

You should be able to just raise the multiplier by one and leave it.

Assuming you don't want to get more performance from your memory. There is a benefit to running faster FSB (it changes the strap on certain boards).

Thx for all the replies guys. I think the only way to know exactly how much voltage is going into my cpu is to get a multimeter thingy. I don't know how much those cost but i'll look into it. Yeah, as im uppin the voltage, im looking very carefully on the temps. The HS cooler I have is the Zalman CNPS9700 LED cooler, which does a pretty good job. I'm just trying to get 3.33 Ghz stable. BTW, the computer crashed while I was out. So imma try upping the voltage alittle more. Now do I have to worry about all the other temps? like CPU VTT, MCH, all those?

Also, when running ORTHOS, can I be doing other stuff like surfing the web and listening to music? Or is that a bad idea?

As was mentioned a few posts above mine...you should be able to simply up the multiplier from 9 to 10. I have my QX6850 running at 3333 now with a simple multiplier change and nothing else. I just finished watching "Shooter" and left the processor priming @3333 with stock voltages and everything went fine.

My CPU is prime stable at 3.8GHz on this Asus board (Striker Extreme). I know it can do more...just not on this board.

I would humbly suggest you move slowly on the voltage and up the multiplier and see how it goes.

Here is another version of Prime that you may have tried. I like this version because it it easier to use. LINKED!
