Want to overclock Duron

Last response: in CPUs

I have a Duron (Morgan Core) 1.0 ( 100 X 10 )GHz processor, MSI K7N420 Pro ( nForce 420-D) mobo, 1 X 128 MB Kingston PC2100 DDR RAM (CAS 2.5). I want to overclock it to 1.33 GHz ( 133 x 10 ). I use a ordinary air cooler for cpu that came from Cooler Master. I don't know the actual model numer, but it's listed in amd recommened coolers list for Duron. Do I need special cooler for this overclocking purpose or my current cooler will do?

The stock cooler may work. I would try it, keeping an eye on heat. If it exceeds 50C under partial load or 60C under full load, you have a heat problem.

No you don't!!! As long as it's running stable with no lockups, you're fine even at 63C!

Not good for the CPU's life though...you're better off running cooler

DOH, what do you really know about that??? Thinking about running a CPU for 10+ years, the extra FSB will kill it before the temp! If he wants to overclock, he shouldn´t be scared of 60C, if it's running stable, it's a good overclock, PERIOD!

Not exactly, while it may not right away, you are affecting it's life and more likely, stability in the long run. I wouldn't be scared of 60C either, but I would't want to run at that temp. Stability doesn't usually come for a while with higher heat.

60C is one of the "rule of thumb" temps. Yes, it will run at higher temps. But while some CPU's will run stable at 65C, others will loose stability at 56C. I've seen this first hand!

If it locks up under full load he has a heat problem, if not he dosent, giving hard tempratures is a bad idea crash.

The damge from high heat takes a long time to manifest itself, certainly longer than the average cpu lifespan(2-3 years) any temp which is stable is NOT capable of detectably lowering the cpus lifespan.

Its time for a new rule of thumb, the new rule of thumb is.


If it is stable, no matter what temp its running at, its ok.

Please stop giving bad advice, based on your own "observations", giving hard temp. rules won't help the guy one bit. Matisaro is right, if it´s stable it works!

He should because ~60C he'd have problems. I'd never let my CPUs temp go higher than 55C even when overclocking (most of them are mid-40).

NO, he probably wouldn´t! It depends on the quality of the CPU, it won´t do anything wrong trying to overclock, even at 60C! Stop giving bad advice, based on your own personal feelings about how "you wouldn´t like to run a CPU at 60C". No one cares if you'd like it to run at 60 or not, it's about the facts, and it´ll not be damaged, just by running at 60C! If it will boot and work stable at 60C, he's fine and shouldn't have to worry about it!

FYI, I have done a lot of overclocking (Athlons Thunderbird, Xp as well as Durons), and in my experience appx. 60C tends to give problems.

Your experince is that 60c isnt stable, but given the cpu is stable, 60c in and of itself does not cause any problems.

The temprature a cpu runs at is not important given it is running stabilly.


For all intents and purposes 40C has exactly the same effect on your cpu as 60c IF the cpu is stable, and if the cpu is not stable THEN, AND ONLY THEN, do you have a heat issue to be concerned about.

I've heard that for every 10C hotter your CPU runs, you shorten the life by 1/2, but can't tell you that from experience. It may be something worth looking into.

You only assume if he can run it stable which he hasn't done so. Wouldn't it be better to reduce heat by using better HSF (especially when overclocking) than gamble to see if it's stable or not at that temp?

No lockups/crashes=stable.

My discussion was towards crash's solid temprature figure, not towards the posters overclocking heatsink request, as you can see I am carrying on the temp issue in several threads atm.

The only reason to buy a more expensive heatsink when overclocking is to overclock further, if the cpu is stable with a 20% overclock using the stock cooler@65C(HYPOTHETICAL AND KEY WORD STABLE) then switching to a 20-40 dollar copper cooler and staying at the same speed to run@45C has NO BENIFIT WHAT SO EVER.

If the 65C cpu is stable(and thats the key!!) then there is no reason 45C is better.

I can tell you that operating spec heat is not the cause of cpu death, electo migration is(and were talking 10 years plus here).

Running hot(65Cish) will lower your cpus life span because hotter traces electro migrate faster, BUT! We are talking shaving months off of a 10-20 year lifespan, so it is not, I repeat NOT a factor worthy of spending 30 bucks for a heatsink on.

OK, well, it's really dependant on the quality of any particular CPU, there were several overclockers who said their systems ran great at a certain speed for a while, then they would only run at a slower speed later, probably heat damage IMO.

It isnt heat damage, the chips are made in furnaces(for certain steps) which go above 300-500C(or more), now the anecdotes you refer to could very well be electrical damage, most overclockers overvolt, and if the overvolting causes some gate damage topspeed can be lowered.

But heat alone? naaaah.

I have a Duron1.2 running standard with CopperHeatsink at 51C , when oc'd at 1.368 (first try)he ran stable at 58C!
Are these temps Ok? I fried my first Duron with standard Hs (certified at 1.4)!

IMO, it seems too high for copper HSF. Did you use artic silver or just thermal compound? I have Duron 1.2G too and it runs mostly at 40C (max load 47C) on Asus A7N266-VM mobo with Thermaltake Volcano III (cheap, alluminium base and quiet fan) in the room has temp around 29C constantly.

do you like to work for nothing? is it pleasant? ROFLMAO. :lol: 

i've plugged my home blower to my case ... dunno what happen ... that works?!?
July 13, 2002 8:01:01 PM

Thanks to all for your advice.

Many of you mentioned that heat is not a problem, if the cpu is stable. I agree at this point. Without overclocking, my 1 GHz Duron runs around 55C under partial load and around 60C under full load (I live in a tropical country and my case is very compact for an ATX size mobo, the power supply unit stays very close to CPU. These may be cause for unusual temp) . One of my friend runs Athlon XP 1700+ over 60C under partial load and near 70C under full load.

But my question is, how much the heat may increase when I overclock it to 1330 MHz (133 FSB). My cooler is cheap and alluminium based. How much it affect the CPU's life (How long the cpu may last in o'clocked temp) ?
July 13, 2002 8:26:46 PM

If I saw my engine temp gauge on my car running just shy of red, I would assume theres a problem and go about repairing it. I agree that 60-65c isnt that big of a deal, but on a hot day, you could get into stability problems, and hit 75C and not know it. It may have been addressed earlier in the thread, but maybe his room/case temps are high, and have the potential to go higher(a/c goes down, heatwave, satans breath, etc...). In that case theres nothing he can do but look for more efficient cooling solutions.

I sold my sig for $50.

If cpu probe temps were as reliable as car engine monitors I would agree, but they are all different and too many variables exist which prohibit a set temp warning limit.

If you run@65C and you get no lockups you are FINE.

if on a hot day you run@75C and get no lockups,YOU ARE FINE.

If you get a lockup on a hot day, YOU ARE NOT FINE.

Point is, dont spend extra money untill you have a problem, dont let some temp reading which "feels" high scare you into paying 30 bucks for a new heatsink if you HAVE NO PROBLEMS!!!!!!!

How hot is too hot, Mat? What temp do you set your alarm at? What do you suggest setting the Mobo protection to cut out at? There is a line there somewhere. I mean just running until you get a lockup, freeze, or dare I say it, burnup, doesnt sound right to me. I would at least re-seat the sink, and try different tempmons until I can get it at a more desireable temperature.

I use thermal compound and my cooler fan is running at 7800rpm(not quiet at all, rather a hoovercraft!)and a 80mm
casefan at 2900rpm !Planning to have cooler air from outside the case directed directly to processor and maybe i try out this arctic silver! does it really make much difference?

60 degrees? in a tropical environment?

Sounds to me that your Duron is doing fantastic.

Just curious, but how high is your room temperature?

I agree with most that stability no matter what temperature is key. However, a good cooler often increases overclocking limits. Find your overclocking limits (with stability) then decide if you need better cooling.

my amd athlon xp 1900 is oc-ed to athlon xp 2000+ (1.69 GHz)yes, 1.69 ghz, just little more than xp 2000.
my cpu is running in range of 50ish C under idle load and 63 under full load
and...
NO STABLITY ISSUES!
i think your computer can handle 65 C... but be careful
