Help with 9650 overclock

post #1 of 8
Thread Starter 
Hello.

Simple question.

my CPU QX9650 is OC'd at 3.6GHz.

I have not increased the voltage and it is still at 1.272 or something like that.


Should I increase this? as I just got a blue screen and I don’t know if that was my ram or cpu that caused the problem

Use a stress tester like DoubleMark or Orthos (I don't know any others actually, lol.) To ensure stability. If its stable, then leave it. Less volts is always better.

DoubleMark

Orthos

Take note DoubleMark supports quads, Orthos doesn't (which is why i recommend DoubleMark, not because i made it.)

most likely ram if you increased your FSB much. Keep the ram at a sane frequency.

yeah you should stress test it. if you can make it at least 8 hours you're pretty much fine (24hrs is better). if you do fail a stress test then bumb the voltage up one notch and test it again. repeat this until it is stable

Ok Will do,

The ram was shipped at 1333 and now that the FSB is higher its at 1600.

the latencys have gone up to 9 9 9 24 and I dont know how to change that with out it crashing.

Is everything ok here?

Will A stress test damage my components, it soundss painful.

No not at all, it's painful but no damage. It just works your system really hard, epecially orthos (which I would recommend). If you run two instances of this it will stress all four cores.
If this is stable for an hour (with orthos things will start flashing red if not stable) , try oc again. When you've reached your goal then check final stability. I tend to run orthos for 6 hours, others do it a lot longer to ensure stability.

If you need help running any of these just PM me and I can help or leave another post.

You should set your memory multiplier to manual so you can set the ram speeds yourself.
Set these below or at the rated speeds so that if orthos fails your can at least pin point what is failing. Are your voltages all on manual?
You just need to make sure you have control over everything so that when you increase your fsb, nothing else is effected by this increase, like your pci express clock.

Very nice reply m8. thank you.

I dont know what to set the volts to if i set them to manual,

I will give this a go tonight.

FIrst i will do a test to see how the PC stands at its current OC. if she passes then i will move on to a speed that is higher.

I will post back with news on this soon.


Thank you again.

If you set the vcore cpu voltage to something low, for this cpu I'm not sure what the default stock voltage setting is I'm afraid. I've seen people on other sites say that it is 1.25 volts, I'd nearly set it to 1.275 myself to begin with.

Then just begin to increase you FSB in small steps as per usual. Also can you check to make sure that your PCIexpress bus speed is set to manual, 100Mhz is default.

I had a nasty experience with this on my first overclock, when my computer crashes due to instability is goes back to default settings and when I went to overclock again, the pcie bus increased proportionally with FSB, it was dying on me and took me ages to figure out why silly me
