I had it at 3.2 for a while, but was a bit too unstable for me. The default is 2.8, and at 3.2 before, I did not change voltage.

So, is overclocking via frequency or multiplier more stable, does it make a difference? should I raise voltage a tad?

Dont worry about overvolting. Main byproduct of extra voltage is heat, if you can dissapate it, its no problem. yes you have shortened proccessor life, but it will be as old as a pentium 4 by the time that happens. I am running my phenom II 1090 at 4ghz using 1.42 volts for rock solid stability. (yes i know thats high, but it crashed before when i tried to render, could've been unstable ram too though). also check your mobo to see if it...

The thing is, I wana play Planetside 2 a bit better, and can't currently afford a replacement. I know it's fairly cruddy, but why not overclock?

I have a decent aftermarket cooler with aftermarket thermal-paste, and 5 case fans. My temps will never go above 48C, even with an (unstable) 3.4 OC.

Ah, but Planetside 2 never goes below 25 FPS in LARGE battles, which is barely playable, and the reason why I want more, but my average FPS is above 45+ everywhere else. I know the 720 is bottle-necking my GTX 650 OCed 25%.

@ funguseater
I'm using a good coolmaster 500W PSU, All I can remember is that I have n aftermarket heatsync, and I'm confident that even a sizable OC will not take temps above 50C, my average right now is 39C. Mobo is ASUS M5A78L-M LX, not the best for overclocking, but it supports it decently well. I do have the 4th core unlocked.

tl:dr

bump the voltage, just make sure your temps are fine. bump voltage, bump multiplier, run prime95 for 30 minutes. use HWMonitor to check your temps.

here is how total freq works its 200 x 20 to get 4ghz (4000 hz) the 200 is the clock, 20 is the multiplier, you do the math and you get the total speed your proccesor is running at. the faster you run, the more voltage you need to keep the signal clear (so the proccessor runs stable)

Depends on your chip. what is your stock voltage now? try bumping multiplier till you hit 3.4 and bump voltage to 1.39 or 1.4. run prime 95 and hwmonitor. if the temps go too crazy high, kill mrime95. (too high is 70c imo, mabee you could push to 75, but i wouldn't). also i doubt planetside will make the cpu as hot as prime95.

I googled it, my voltage should be 1.325, lol, I'm TR btw. I'm really trying to raise my low end frame rate, 35+ would be nice. But in most places, its like 45+, with is certainly playable.

i used to be scared too, but when i saw the ln2 overclocks with obscene voltages of 2 something or 3. i deduced that its not voltage that kills but heat, and if heat is manageable, it is non issue. I'm also TR :DD Infiltrator, (they need to give the class a few more perks..

yeah, lol.

Currently, I have unparked my cores, disabled power savings, and set pre rendered frames to 1, and use razer game booster ,this is a good help, and the last thing on my list is a healthy OC.

Ok, so It boils down to this, I know I should be able to get 3.2 easy, but it doesn't seem to be stable. My guess is that I need to change a couple settings, like north-bridge speed etc. Any help?

He's probably right about that bum core :)
I already posted the guide.Not sure what else to tell you.
1.35 is pretty low for a Deneb..i'd say 1.55 IF the core temps don't go over 55c.

And what about my NB. I have some 1600 RAM, which I hear OCing NB can help take advantage of. I also hear it can help stability.

It's currently at 2050, (50 because of HT ref clock is 205) and the voltage is 1.2. I',m thinking an extra 225Mhz, or more? What do you think?

I see what you mean regardless man.
Anyways. I set my NB frequency to 2255 at not extra voltage, should I go higher, should I add more voltage? I know some of you peeps don't think Ocing for me will work well, but I think NB frequency will help regardless.

My gpu is the GTX 650 overclocked 25 percent. It can run PS2 on high no problem. High and low give me the same FPS with very little change. I'm playing at high right now.
Please stop "helping" if your not helping.

Ok, I got to 3.4 stably by setting voltage to 1.475, and turning up the multiplier + HT ref clock. I also sped up the NB by 400 Mhz and turned the NB voltage up by 0.05. PS2 no longer goes below 40 on any part of the make unless they're 100+ players at that location. That's a 10FPS boost (would lag at tech planets and bio domes @ 30 FPS), and big battle have gain a few FPS, but it's hard to completely measure because it changes a lot.

A healthy boost for PS2, which I run on high, but a substantial boos to Starcraft 2, which I run on ultra. SC2 never goes below 45 FPS, very playable when it's 50+ on average.

ALSO, as result of my overclocks, (Ram set to 1600 from 1333) and the CPU + NB, my SSD has gone from a 7.4 to a 7.5 in the windows rating scale. My ram has gone from 7.2 to 7.5, and my CPU from 7.2 to 7.4.

I thought you told me it would not help at all. Seems you were wrong.

A good target zone for CPU/NB is 2600-3200Mhz
You can raise CPU/NB voltage up to the Vcore voltage.
but..i usually start @ 1.375 and adjust from there.
You will have to lower the HT link as you increase reference clock to keep the HT link around 2000-ish.

yes..that's in the target zone.
