Hey guys I'm new to this forum, and new to overclocking...
I am trying to get a little more out of my processor but I have been having trouble.
So far I have gotten this far...

This is my cpu running full load.

So far the only settings I have been messing with is the Bus Speed and the CPU voltage (CPU v)...
I increase the the Bus Speed one notch then another and so forth until my system will not boot at that point I then raise my CPUv one notch Then my system will boot. But at this point I am unable to get any farther without my system refusing to boot...
What am I doing wrong? Do I need to adjust different voltages also?
Right now I am stable with the settings in the pictures listed above.
This is what my Memory is running at right now...

Here is my computer specs:

MotherBoard:
MSI 790FX-GD70

CPU:
AMD Phenom II X4 965 Black Edition

Memory: Corsair Dominator DHX TW3X4G1600C9D 4GB Dual Channel DDR3 RAM - PC12800, 1600MHz, 4096MB

If anyone has any settings I can try to get this processor running faster please help me out thanks!

It's unlikely for a rev. C2 Phenom II to reach 4GHz on air.

You are more likely to reach 4GHz with a rev. C3 Phenom II.

You have a black edition processor so you can OC using the CPU multiplier instead of increasing the bus frequency. For 3.8ghz, you'd want 19x*200mhz, for 4ghz, 20*200mhz This will let you keep your ram at 1600 mhz, right now that's probably what is limiting your OC since you have it at 1720mhz and unless you give it more voltage it probably won't do that.

Here's a good guide you should read before going any farther:

Lol... I got this error While running Prime95 At the time I was using the OC dial and took the CPU to 3.7GHz wile running the test my temp never got over 56c... I took the CPU back down to 3.6GHz and this time didnt get an error with Prime95. Here is the error I got in Prime95, While my CPU was running 3.7GHz under full load...

It would be much easier to overclock your cpu and find it's limits just adjusting the multiplier, than if you want to mess with overclocking the ram/northbridge as your currently doing, you can do that too. Right now it is probably either your ram/northbridge that is limiting you, upping the voltage for those may fix the issue.

You are running your DDR3-1600 at 1720MHz. You need to drop the memory ratio (or, IIRC, MSI has some of the few AMD motherboards that actually have memory divider settings in the BIOS)

Like others have said above me, you have an unlocked multiplier Black Edition: Use it.

Lower your Bus speed back to stock (200MHz) and just increase the multi by .5 until whatever test you're using (prime95) errors out. That should give a pretty good idea what speed that CPU will achieve given whatever voltage you're pumping through it. FYI, the safe upper limit you should be working with is 1.45V, with 1.5V being the maximum limit you should stay shy of if you're using air-cooling.

There are a couple of good reasons to do it this way:

1. It's a pretty straightforward and easy way to overclock the CPU
2. You don't risk forgetting about some other clocks (RAM, CPU-NB, HT) which all get pushed up along with the base clock. E.G., you could be thinking that what's holding you back is the CPU @ 215x17=3655MHz, and up that voltage, when in all likelyhood, it's trying to run your PC3-1600 DDR3 @1720MHz, just like scheiderguy said. Or maybe it's your 2150MHz CPU-NB running with stock volts that's causing you to have errors (though this is pretty unlikely; stock volts are usually plenty to get the CPU-NB running in the 2.2-2.4GHz range)

So, set your base clock back to stock, and slowly increase the unlocked CPU multi until you hit a wall. Then, considering temps, and voltages, you can decide whether or not it's worth it to try and bump up your CPU volts one notch to achieve stability and then perhaps try to push the multiplier up another notch.

You may want to consider lowering your RAM speed to 1333MHz at this time, just to take it out of the equation. And check your temperatures. Staying under 55C is a pretty good idea, although you won't be burning anything up if you let her run a little above 60C. Oh, and try to keep an eye on your PWM temperatures also: it really wouldn't do to cook your motherboard, now would it? ;)

Eventually, when you've found the point at which your CPU cores just don't give you any more love, even with the extra volts, you'll probably want to start increasing the CPU-NB multi and try to get that running faster. At which point I would suggest putting your CPU back down to stock and just experiment with overclocking the CPU-NB using it's own multiplier. Then you can then try combining both for a much snappier system overall.

Finally -- and I'm cutting this short now because I haven't told you anything that hasn't already been carefully detailed in a number of good AMD Phenom II overclocking guides across the net -- you're probably best-off setting your sights on 3.8GHz. Your time will be better spent clocking your CPU-NB and then getting you RAM to run optimally, than by just fighting an uphill battle trying to hit 4.0GHz on that C2 stepping 965 of yours.

And hey, once you get 3.8Ghz CPU / 2.4-2.6Ghz CPU-NB running nicely with the least amount of voltage possible (i.e less voltage = less heat = more potential overclocking overhead) AND you've thoroughly tested your RAM to make sure it isn't throwing up errors which one might sometimes erroneously attribute the the CPU -- once you've down that, you can try and get it to hit 4.0GHz in the coming hours/days/weeks. IMHO you would do well to remember that an extra 200MHz (less than 5% extra performance) isn't all that important in the great F-ing scheme of things.

In any case, I wish you the best of luck, just like another poster wished me when, a couple of months back, I was pulling my hair out trying to get 4.0GHz stable on my then new C3 965.

My memory was running at like 1033MHz and I set it to 1600MHz if I lower that then It wont be as fast correct?

Agreed. But they are telling me to set the memory to a (Not as fast) setting. I was just wondering how that would benefit me.

lower memory frequency may allow you to run tighter timings.

every gigabyte AMD mobo i've ever used has mem divider settings. And OP try and keep HT link speed around 2000mhz by altering the HT link multiplier/ divider.

lower memory frequency may allow you to run tighter timings.

Indeed. Sometimes you have to drop down to a lower memory frequency. Throughput can be increased by tightening timings to the limit. You will still have the added latency of the lower memory speed but fortunately not too many programs are latency sensitive. (This certainly is not going to make a difference in the "seat of the pants" feel of everyday computing!)

I see. I am a gamer. so should i go that route?

The ideal route is to get things going the fastest and still be stable. Once you find your limit back down a few so you have some headroom to allow for warmer days, less than optimal cooling due to dust building up, etc. This assures glitch free, enjoyable game play without embarrassing blue screens or lockups. ;)

If you downclock your ram and tighten timings you MUST check memory for errors as often the system will seem more stable but if the memory is erring out you will run into problems down the road. Remember memory throughput is limited by the quality of the chips used on the modules. There's more than one way to "skin a cat" as they say so whether your ram clocks are high with less aggressive timings or your clocks are lower with tighter timings the throughput limits are still there. Sometimes you can squeeze a bit more either way. Sometimes you have to increase VDIMM (going over manufacturer's maximum is strongly discouraged for 24/7 use! Once you have to increase VDIMM you're at the limit of the memory.
