overclock cpu?

[goodluck]

hello all. I have already overclocked my cpu from 2Ghz to 2.8Ghz. My friend told me that overclock can break cpu or motherboard. I wonder, this is true?

Yes, there is the possibility of ruining your board because of overclocking. The CPU is at a bigger threat IMO when you overclock, a lot more sensitive to voltage changes then motherboards are.

Well, I wanted to recommend you to not overclock that P4 is that is the system that you actually overclocked because P4 runs very hot and you will most likely burn your chip if you don't do it correctly.

Be careful when overclocking P4, especially if your using the heatsink that came with the processor.

And yes, it could permanently damage your whole system.

Even the overclock friendly core2 duo overclocked from 2 to 2.8 on stock cooling isn't a good idea as your pushing beyond the bounderies of what is considered safe on stock cooling.

Overclocking the p4 to that level on stock is just insane

As soon as you notice your PC is crashing for weird reasons you know you pushed it too far, it's that simple.

Otherwise, there might be long term effects, but who cares whether a CPU will last 10 years or 5, it will be replaced in the meantime anyway. So just let the thing live to the max

Let It Live Damn It!!

how safe is it to overclock a Q6600 with good cooling?

Very very safe if you have good core2cpu/ram/mobo/aftermaket cooling and you keep the temperature below 50Celcius and do low to moderate overclocking and maintain default voltage.

If your doing moderate overclocking all you need to worry about is monitoring the temperature.

The safe zone for core2 q6600 tjunction(internal cpu temp) is below 60 celcius.
go to anandtch forums to find out more about it.

You can potentially up the voltage and the temp to +70Celcius but you'd probably be giving your cpu an early grave.

Well, there's a question I'm wondering a lot about and I suppose this is as good as any other place to ask about... (very stupid/basic question but... Dangit I wanna be sure about it )

When looking at my temps I see "CPU" and "Core1" and "Core2". (I'm using a e6600).

Overclocking it from 2.4ghz to 2.9ghz (a little tad under that) I get temps of about 61C on CPU and 72C for both Cores. That's higher than I wish it was, but that's only when torture testing it (and if I don't open the case to give it a better airflow, if I do it stays around 69C).
CPU at 44C and cores around 52-54C when idle.

Now what I'm wondering is...

When looking to overclock my CPU... Am I supposed to look at the "CPU" number, or the Cores number? I've been told to keep the temps under 70C... But I can't figure out if I should keep the CORES temps under 70 (which would make sense since those are closer to 70C and since I'm increasing the speed of the cores) or if I should keep the CPU temp under 70C (which would makes sense since it's named CPU after all... But the temp increase kinda too slow and I'm afraid to hurt the cores by following it).

I think I got a early/bad version of the E6600 anyway (I did buy it a long time ago x_x maybe it's time to go for a newer G0 Quad)... It overclocks so bad... Or maybe my hsf is simply very very ugly... I tried using a big-ass fan to blow toward the cpu after opening the side of the case but sadly it only shaved of 1 or 2 C, meh.

[PCXL-Fan]

I'm assuming from your post you have one of the B2 Stepped e6600 core2 duos just like me

Using SpeedFan to measure the core temps you want to keep them under 70C, the cpu temp also called the Tcase temp.

E6x00: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 65w, Delta 15c

-Tcase/Tjunction- (cpu/core)
--60--/--75--75-- Hot
--55--/--70--70-- Warm
--50--/--65--65-- Safe
--25--/--40--40-- Cool

[Thanakil]

Hmm... So the temps I have right now are kinda too high? I was hoping to get it a little higher . I suppose I should reduce it to 2.80ghz and keep it "warm" only =/ oh well... It's not really fast but it gets the job done I suppose.
Thanks!

Well just spend 70bucks at NCIX.com - Canada's Premier Computer Store and get some arctic 5 thermal grease and an thermaltake ultima-90 heatsink and you'll be able to hit 3.3ghz or more at lower temps

I don't overclock mine higher than 10% over default to keep in the safe zone with my stock cooling.

I used this great article, it'll tells me pretty much everything I need to know about cpu temperatures
http://www.tomshardware.com/forum/22...perature-guide

[Thanakil]

I think I may be a bad overclocker to start with, I had been using a too high voltage... x_x

Reducing it to something like 1.3375 or around and I have lower temp atm. 57/67-67 (max it reached when doing a torture test)... CPU-Z tells me the core only uses 1.240V anyway x_x.

Anyway, it does seem like I have a B2 revision. But I don't really feel like spending 70$ on that =/ dunno, it seems like a lot to simply overclock. I'm mainly wondering about the 12$ grease... Isn't that a little much?

[PCXL-Fan]

hmm don't know about artic silver by itself, why not just google a review of it.

Cpu-z will tell you what stepping revision you have.

Yeah that's how I became aware of it (stepping 6 revision B2). I decreased my voltage from 1.3375 to something like 1.31xx but my pc is becoming a little slow when booting up, and I think randomly takes too long on doing something (but that could be me being paranoid). My speed is still rated as 2880.3mhz when doing the torture test tho. Does it mean my voltage is good, or should I increase it? My speed is rating as 1900mhz when idle, so if it goes up to 2880mhz (which is what I overclocked it to) when running fully I suppose it means the voltage is enough for the cpu?

Anyway, I suppose I'll try to get some stuff for about 40-45$. I don't wanna spend too much on fans only but well, it could be quite nice to have something better than the stock hsf.

[PCXL-Fan]

If it runs a prime95 or orthos torture test and also memtest86 test for many hours without a hickup your probably fine. To be even more certain run 3dmark06 on a loop for about 8hours.

Can't afford the thermal grease? Dan of the famous Dan's Data tested toothpaste and found it has slightly better thermal conductivity than Arctic Silver 3(not arctic 5 btw) I'm not joking...

Thermal transfer compound comparison

Only thing about the tooth paste is in time it will eventually dry out.

[StriderVM]

No. Don't use toothpaste. It's just a joke, even the author of that article doesn't even suggest it.

I want to overclock my AthlonX2 but i dont know what cooler i need to do it without damage the computer?
pc specs
Motherboaed: ABIT AN8SLI
CPU: AMD ATHLON X2 4400+ 2.2 GHZ
RAM : 1GBDDR 400
GPU:8600GT 512MB.
When i overcloked it to 2.3ghz long time ago it worked ok, but when i try to overclock it any higher than 2.3ghz it crashes.

[StriderVM]

Well, maybe it's just your luck. Before I was able to overclock my A64 X2 3800 (2.0Ghz) to the max my motherboard can overclock, at 232Mhz FSB. (2.32 Ghz) .

The motherboard doesn't even have any voltage settings.

Does your motherboard have RAM Timing settings? It's because increasing FSB also increases your RAM speeds, in which if the RAM can't take it, it will also crash. So I suggest tweaking your RAM timings.

The other thing I can suggest to you is increasing your CPU voltage, but only in very small increments. If your motherboard doesn't have voltage settings, you're out of luck.

In any way, I suggest looking at your computer temperatures. The biggest enemy of overclocking is heat, followed by RAM timings.

[BAXTER STOCKMAN]

Well i downloaded ntune . ntune is a overcloking tool that lets you overclock cpu,gpu, pci bus, even motherboard bus Also i can change the Ram timings roo. It says that the ram timings are 8-3-3. Now if i change it will the pc work faster?
