AMD Phenom II X2 555 BE Unlock and Overclock on GA785GT-UD3H

[gothicfighter]

😛 Nice explanation. I like the gun. Now, I have to increase the voltage to 1.35V, right? Nothing bad will happen , I hope
ps: A reply on another thread on i7 voltage:
"Lower voltage is always good. As long as it's not crashing or anything like that, I would not worry about it at all. With that voltage though, I bet you're talking about idle voltage. Load up the CPU with something like Prime95 and I bet the voltage will climb to 1.1V or higher."
His was ~0.97

Don't worry about the voltage as long as you keep it under 1.52v and you monitor your temps.

The only way your voltage will drop below spec's is by having Cool n Quiet enabled which obviously should be disabled when overclocking.

 

[gothicfighter]

Well, I have Cool'n'Quiet enabled. I bet this is why the voltage is 1.25 when idle. I'll monitor the voltage under full load and see where it is. Since I'm not overclocking right now, should I leave the Cool'n'Quiet enabled?

First rule of overclocking :

DISABLE : CnQ

You will en-dup bashing your head against the wall when you realize that Cool n Quite "underclocks" the CPU when idle to save power.

When you are overclocking the CPU needs a constant amount of juice, the purpose of CnQ is to reduce the CPU voltage which in turn screws up the whole process all together. Hope this explanation is good enough for you to understand =)

 

[gothicfighter]

That's right, disable if I'm overclocking. But right now I'm not. So my question is if I should disable it now, when the CPU is not overclocked.

 

[OvrClkr]

If you are running at stock clock then yes you can enable CnQ, but like I said the purpose of CnQ is to save power which defeats the whole purpose of overclocking.

If you are not OCing or even if you are OCing if you are not increasing voltages to remain stable then leaving it on should be fine - the problem comes when you are OCing as it will not always return to the same voltage that it was set at when you begin to stress the CPU so if you are trying to push an OC and remain stable by increasing the Voltage then CnC lowers the voltage you can sometimes lose the system stability as it will just return to the default voltage instead of what you increased it to manually thus defeating your work !

 

[gothicfighter]

Yesterday I've disabled C'n'Q and increased the voltage to 1.30. I've done this after Assassin's Creed froze after a couple of hours of non-stop playing. Went to BIOS and the temps were normal so it's the game that's the faulty one.
Anyway, all has run fine and stable.
PS: since when I bought the new PSU(about 5 months ago) the +5V voltage was kinda low (about 4.5-4.8V)Could this produce a crash?

 

[OvrClkr]

The 965 C3 is the at the exact same CPU as the B55, the 965's stock voltage is around 1.38/1.4v, so this tells you that you should not be giving it anything less than 1.35v at 3.2Ghz.

 

[gothicfighter]

Oh, so then I should increase it to 1.35, right? Anyway, found the problem(99% sure) All these crashes started as soon as I've uninstalled DirectX 10 for XP(what a big dumbass I am😛). When I've checked dxdiag, the reported version was still 10. Gonna make a new thread about it.

Yes raise the voltage to at least 1.35v (1.38v prefered).

Any reason why you would have to uninstall the Direct X on your comp?

'cause XP doesn't support dx10?

 

[OvrClkr]

Correct, but then why would he have DX10 to begin with?

 

[welshmousepk]

Correct, but then why would he have DX10 to begin with?

because he installed Dx10 for Xp as he said in his post.

this causes more problems than it ever solves.

 

[OvrClkr]

How do you install DX10 on a machine that is running XP?

When you install the driver, it will automatically install the correct version of DX depending on the OS he is using.

Im lost here....

perhaps i should have used more apostraphes. 😆

'Dx10 for XP' is a crack (or something to that effect).I dont know a great detail of how it works, but i think it software emulates some features of DX10 to allow dx10 games to run on xp. but as i said, it usually causes way more problems than it solves.

the confusion is understandable though.

 

[OvrClkr]

yea now I understand, lol... I was under the impression that he had mistakenly downloaded the wrong driver, meaning he had chose a vista/DX10 driver instead of the XP/DX9 driver =)

Then what would be the results of using a 5xxx series card which require dx11 on a system running on XP? Would that make the gpu under-perform?

nope, not at all. you would simply not be able to activate any DX10/11 features. and wouldn't be able to play dx10 exclusive games like just cause 2.

in DX9 games, performance would be the same though.

 

[Starges]

Oh.. thanks
