Whats the difference between the Northbridge and the Southbridge?

Pending a bit more mastery with overclocking my CPU, is there a way to get at my GPU?
Your northbridge is between your CPU and your RAM (not necessarily physically) it is basically a bridge that all the data you use goes over, thing of it literally as a bridge and the CPU and the RAM are two cities, that bridge is only so wide. So to get more cars across you up the frequency or the speed limit. (not too fast or you bus will roll over <- i know you like that pun) So even a small boost in you NB will speed up daily activities, like opening Firefox or Word (if you noticed i use ubuntu, so at the moment i am not too too worried about CPU clocks, but im looking at getting a new CPU soon)

Your southbridge is basically a traffic light, it controls stuff. Your sata ports, graphics card(s) and other stuff (i think at least), you can't overclock that.

to tackle your GPU use something called rivatuner.

i could explain how to do that but, this guys does a fine job


When you start overclocking (i hope your buying cooling later too!) and you hit a "wall" where as you can't go any faster even with more voltage, again,
DO NOT! go above 1.55v in your BIOS, post back and we'll work from there

So I've hit what I believe to be one of these walls. My multiplier cannot go any higher without BSOD on or very soon after bootup. But my FSB so far is going up without problems. I haven't touched my voltages yet. My cpu is hovering just under 40 degrees without any load

load it up, and the BSOD is either RAM or NB, try bumping your NB up a bit, go from 1.22v to 1.24v then try one of the stress testers i linked you to.

BTW, what is your clock now?

I'm at 3.8 with everything at the supposed defaults except my RAM which is at 800 as opposed to 667. The multiplier is at 19 and can't go to 19.5 without BSOD. So, I'm gonna keep the FSB at defaults and bumb up the NB? Voltage, frequency, or both?

EDIT: Okay so I've now returned the RAM back to its stock 667 so EVERYTHING is normal (assuming the stock NB frequency is 2Ghz) multiplied by 19. All tests until this point have, within seconds of testing, resulted in BSOD. Re-testing now.

I just want to reiterate the bit about Prime 95

Please keep in mind it doesn't matter if you can boot the system up what matters is if you can survive a few hours of Prime95...if one of your cores or your entire system crashs you need to work on your voltages/clockings

I recommend putting your NB/Ram and everything else there is back to stock...you want everything else at stock because if you crash you can't be sure that its the CPU/NB/Ram if your not 100% sure they where stable to begin with...start first by overclocking the CPU and getting it to be Prime 95 stable

Shoot for 3 hours stable in a blend test that way we can assume ATM it is a pretty stable clock and not spend all day testing it out...then work on your NB/Ram etc

I recommend a NB overclock of no less than 2600Mhz for your system and if you can control the temps and your Mobo/CPU is capable of it you should try 2800Mhz as shouldn't be much trouble to obtain with your CPU

What CPU cooler are you currently using and if you can load up a temp monitoring app can you tell me the temps you are getting in Prime95 before you crash?

I suggest you download the application core damage...your system should be able to run this even if its really unstable and what the app will do is give us the maximum possible heat output of your current voltage/clock setup...based on that we can get an idea as to how much more voltage you can safely load on the CPU

I'm using stock cooling but its not attached to the cpu fan port, its attached to a port that makes it go much faster... was this a bad idea? Is it also a bad idea to attach a second fan in the same direction and same speed?

I don't know what my NB stock is, and with the NB voltage up to 1.25 and the frequency at 2.2 I still got BSOD so I'm gonna try a test with no overclocking at all... I also don't know that my HT Link default is either.

with my ASUS M4N82 Deluxe, i haven't been able to do more than 2400Mhz on the NB and remain stable.
And RewindLabs he already stated everything is stock accept for his CPU.

OP: what you should do is up you CPU voltage a bit. First look at you stock voltage in CPUz and up that by about .500 volts, or 4 notches in the BIOS.

Try running a stress test, 3 hours of linpack should do the job (3 hours of intelburntest of CPU:linpack under OCCT)
and if your doing a 24/7 overclock i would say keep your voltage at 1.5375 max in your BIOS. BUT START TESTING! I've had my CPU fail test 2hours+ into OCCT

NO just because i said don't go above 55C doesn't mean that you will reach it. Phenom II chips LOVE cold temps. Mine becomes unstable beyond 45C

stock NB clock is 2000Mhz and 1.22v

Run the NB at 2000Mhz and HT link at 2000Mhz

Always try to keep the HT link at 2000Mhz as it actually reduces performance when you over or underclock it...if you are FSB overclocking where you have to mess with the HT link try to keep it under 2100Mhz or above 1900Mhz...just work with the multiplier overclocking atm


Sorry i am signing out for an hour or so...watching Dirty Harry in Magnum Force (I LOVE CLINT EASTWOOD!)

Thats odd...as far as i know the stock HT link speed is supposedly 2000Mhz? or is this something to do with your specific board?
