How to get higher O.C.

[purple stain]

It seems that i am maxed out in terms of the CPU Multiplier.I have reached 3.9ghz with 19.5 for the multiplier and vcore at 1.425.Which isn't much at all,i thought i was going to have to crank up the voltage a lot more to get where i'm at after i read a couple reviews for o.c.ing my prossesor.So my question is does anyone know how i might be able to fine tune or get any more out of my prossesor.My goal was to hit 4.0ghz but i fell just short.I've tryed playing with the HT Link just to get another 100mhz but it wont hold.Just to unstable.Any help or comments would be helpful.

Phenom ii x4 965BE @3.9ghz/1.425volt

4G DDR31600mhz currently at 1333mhz because of mobo.

Hi.

HT don't give you much performance, but NB is a different thing. Some 965 can hit the 4GHz or 4.2GHz with good settings and cooling.

Start to rise the NB frequency and you will see some performance changes.

How would i go about doing that?(detail)
I am still fairly new to this sort of stuff.
I'm a lil iffy about anything having to do with the NB.I've tryed raising the voltage and speed of it before but it wouldn't even boot.Had to reset it.Redoing all of that is a pain thats why i try to stay away from it.

 

[saint19]

Go to your BIOS and star to rise the NB Frequency option, keep in mind tyhat with a Deneb core you can go until 2600MHz maybe 2700MHz but no over that.

If you need rise the voltage for get it stable, your need change the CPU-NB voltage options, the NB should be on "Auto"

 

[purple stain]

What will increasing the NB freq do or enable me to do?Will it allow me to keep raising the CPU multiplier?Will i have to change any of the settings on for the RAM?

 

[saint19]

Run your RAM to 1600....

 

[purple stain]

For some reason i can't i fnd a stable setting.I've tryed but it just won't do it.I think it's the mobo.It's not rated at 1600 by default.It can only be obatined thru and O.C.The dummies at cyberpower put in 1600mhz instead of 1333mhz.Or they configured the mobo wrong.I'm not even sure if thats correct or not.I just know that i've tryed a lot of different timings and none of them seem to work.

Look here:


I'm guessing those are all the frequncies my RAM supports.I've tryed the 1600mhz settings but it won't go.Do i have to adjust the RAM in order to increase the NB?

 

[saint19]

What voltage and frequency are you using for NB? Leave the RAM in auto for now.

 

[purple stain]

NB volt and freq are at default.I haven't tryed anything yet.

 

[saint19]

So, Why you say that isn't stable?

 

[purple stain]

What do you mean?
Since my RAM in Underclocked does it abosultelty need to run at 1600 to O.C. the NB?
I assume the NB O.C. is so you can O.C. the CPU Multiplier more?

I can agree with O.C.ing the NB but it's the RAM timings that creates a huge pain in my ass.

I've been able to get to 3.9ghz so far without altering any othe settings beisdes the CPU multiplier and core voltage.But it seems like i can't get any furuther without messing with the mobo itself.Mob itself+NB or RAM.I know i can tweak the HT Link to where i can go but the RAM Timings just screw me up.I'm only at 1.425 Above the stock i bleive i have so much more to obtain but it's all because of this stupied RAM.

 

[saint19]

Your RAM should run at 1600 with CL9, at this moment you are running 1333 with CL9, so, you are losing performance.

Go to the BIOS and set all the specifications of your RAM manually.

 

[purple stain]

What is CL9?

I toald you i have tryed setting all the settings manually for it and it doesn't want to.I ran Prime95 for 10mins yesterday at the regulated speed/volt and it didn't work.

 

[saint19]

CL is Cas Latency and in easy words are the internal specs of the RAM, those number are the time that takes the IMC in ask for info and RAM to reply with that info.

Are you mean that at stock speed prime95 doesn't run?

 

[purple stain]

Let me try to make this understandable..i've run the settings i've found for the 1600mhz in the SPD which is what i is reccomended for the settings.But my mobo decides to keep it is at 1333 even tho it's 1600 "rated" buy it desn't hold.I run Prime95 test with lots of ram tested and it fails afterd 10mins so i think it' something to do with minor things.

I'm counting the days for the new AMD Bulldozers series toget here in Aprile so all i'm doing is waiting.

I've asked os many times to O.C. in this forum but everyone comes up with the sa,e fourmes.If you can give me a guide to O.C. the NB i will be more than wlcome to take a looks at it.But for now keep it at 3.9 until the new Bulldozer chips come out this April.

Thats what i'm really waiting for.!!!

Ok.

The NB is rated at 2000MHz by default, you can get good performance rising the CPU frequency but if you rise both, CPU and NB frequency the performance will be much better.

Now, to overclock the NB you need use the same steps that you used for overclock the CPU, change from "Auto" to i.e. 2200MHz and test the rig for stability. Here you also will need find the correct voltage for the NB, that option is located in the BIOS as CPU-NB voltage.

 

[purple stain]

Will i have to adjust the RAM timings if i start to O.C. the NB or is that a enitrely seperate thing?

 

[purple stain]

Ok i just put the NB Freq to 2200mhz and bumped volt up .250,it seems to be holding.So i'll just keep O.C.ing.Should i raise the volt .25 every 200mhz or 400mhz?

What exactly does the NB do?What will i gain from O.C.ing it?

 

[saint19]

Not always, rise 1st the 200MHz and if you don't get it then rise the voltage.

The NB gives your more performance from your 1600MHz RAM linked with your CPU.

 

[purple stain]

Is their anyway i can gain more for my CPU so that i can hit 4ghz?

 

[saint19]

What is your CPU revision/model?

 

[purple stain]

RB-C3.

 

[saint19]

Good, with that CPU you will need a voltage between 1.5 and 1.55V not more, adn remember you eyes on the temps.

 

[purple stain]

I think max is 1.55.
I've tryed 1.5 or even 1.55 with multiplier at x20=4.0ghz but it wouldn't hold.
Will O.C.ing the NB help obatin that?
I'm only 100mhz away from 4ghz i don't see how it could be so hard.
