Any input on my OC experience is appreciated

post #1 of 14
Thread Starter 
I just purchased an AMD Phenom II x2 965 and I am trying to OC it. I used some OC software called TurboV (photo 1) and I achieved 3.8 GHz pretty easy (photo 2). I was wondering, what are most people getting out of this CPU? Ive been reading some places that 4GHz plus should be achievable.

Also want to note that I am using TurboV because I am not too sure about the settings on BIOS. For example, in TurboV you have CPU frequency and CPU voltage. In the bios I can see Processor voltage... Is this the same as CPU voltage in TurboV? Also, I cannot locate the CPU frequency in Bios... Only the CPU bus frequency (is that the same as FSB?).... I also notice that I cannot select CPU ratio from auto to manual which probably unlocks the the CPU frequency...

Can anyone advise me about these bios settings? Does anyone have any comments or advice on this setup? I'm not joking when I say I reward good advice with gift cards... Ive done it lots in the past on other forums. Good help is greatly appreciated. Thanks in advance.

You should always OC in bios rather than with a program. CPU voltage is same as processor voltage and CPU bus frequency is FSB. Are you sure you cannot change the CPU multiplier? Your CPU is black edition so it should be able to.

Other than that, looks like a good OC. Nice voltage for that frequency. How are you temperatures? Maximum temperature while stress testing should be kept under 62c, which is the max safe temperature.

Also drop your HT-link Frequency as close to 2000 you can. If it's any higher it can cause instability.

Hmm.. I advice against using any software tool for OCing, and if you are to use SW tools, then at least use AMD's.

Now, don't play with the voltage much. Those CPUs have a rather large voltage overhead, you won't need to raise it much even for 4Ghz.

The CPU freq is the result of the calculation CPU ratio * Ref clock (what you call FSB, except it's not called FSB anymore ). If you can't touch the ratio, just rise the Ref Clock.
In my sig there is really easy beginner-friendly guide for OCing. It's for Athlon II but the exact same applies to Phenoms. Go through it, it's not too long

Use the Bios mate, Much higher chance of damaging components from voltage etc from using software as your already booted into the OS utilizing them.

And 1: thats a quad-core not dual core, 2: your cpu voltage is a bit too high for that OC imo (but you can leave it alone, if your going to OC it further), and 3: your using the the HTRef/FSB to OC only, which will limit you, rather then doing a bit of both, ie: multiplier and fsb, or just multiplier, im certain the 965 multi is unlocked.

Thanks for all the input already.... I will definitely go over those guides... You all seem to be mentioning the CPU multiplier.... Where is this setting on my bios? Im sorry, but I am not too sure what a multiplier is, but at least I know what I need to research next....

"CPU Ratio" seems to be your multiplier.

My bios will not let me select the CPU ratio.... Strange, I even updated the bios.... Any ideas about that? I'm not too sure what to do.

Some Bios don't have a multiplier selection, just bear in mind. You manually type in the multiplier. (EG: its says "Auto", you highlight the option, and type in "20") just an example. Because that chip is unlocked, therfore you do have an unlocked multiplier, you just need to find it ^^

One more annoying newbie question.. Is the multiplier the same as the CPU frequency? I just Googled CPU multiplier and read an article about how changing the multiplier will not affect the bus timings or memory timing which would be nice.... It also said that some CPUs have this locked.... As you guys have mentioned as well..... Hmmmm, how can I tell if its locked? perhaps I should google that as well.... Thanks for all the input thus far... Im getting some new leads to hunt down...

I posted this before I read the last comment, I thought the multiplier was unlocked... It had to be

The HTRef/FBS (both are the same thing) are a reference for the components on your machine to check what frequency their to run as depending on their multiplier. EG Your FSB is 200. and your cpu multiplier is 20, your HT multiplier is 10, then your cpu frequency is going to be 4GHz, and your HT link will be 2GHz.
