Overclocking question?
 
So I did use the SEARCH function prior to asking this, and I looked elsewhere as well, but I didn't find exactly what I was looking for and nothing was conclusive anyway... SO with that said here's my question:

I have a Core 2 Duo E6600 and I want to overclock it. I'm using Speedfan to monitor temps but I want to know what are safe temps for the chip to be at while idle and under load.

Right now my temps are 31c and 33c respectively (this is with WMA open and a bunch of windows). I've heard that neither core should exceed 60c... is this correct? I know about Orthos testing and TAT to make sure the overclock is stable. Also my ram is DDR2 800 MHz so it should be twice the frequency of my fsb to be 1:1 with it right?

Is there anything else I need to know before I overclock this puppy? Mind you, I'm only shooting for 3.0GHz overclock so I just need to know the basics.

If you want a 1:1 ratio, try to go for 7x430. Your ram should work great, I just checked it out on newegg, nice timings. Might want to loosen them just a bit if you go for 850Mhz+. Depending on your cpu cooling, you could go alot higher then 3GHz, around 3.4-3.5 on air.

When stress testing, raise it small intervals, don't jump straight up to the exact overclock you want, ease into it. Check your stability in benchmarks like 3Dmark06 first, to make sure its atleast good for that, then run orthos. repeat this until you reach the clock you want. 3GHz should be no problem. If it becomes unstable, raise the voltage a little. You're correct, you dont really want to go over 60*C, its not the end of the world but not the best practice. Anything over 70 i would consider dangerous. Voltages depend on your cooling once again. I wouldn't go over 1.5v, and really, you shouldn't have to.

Once you reach the final speed you want, stress test it in orthos for an extended period of time. I would recommend trying to find the lowest voltage that clock will run at, not just sticking with the first thing that works.

This is the best I can do to help you out, considering I don't have all my parts for my core 2 system yet. Should be here wednesday though :D Best of luck in your overclocking.

Is it true that merely overheating (to shutdown temp) the cpu by overclocking wont damage it ,but feeding it too much volts will, Ive never tried blowing mine up so I wouldnt know.

Overheating can lead to throttling (if enabled in your BIOS). Thus your processor should be safe.

Overvolting can lead to circuit failure. Thus, your processor is useless silicon.

Therefore, you are indeed correct. If you want to blow up your processor, overvolt it to hell. :naughty:

Not entirely true. When OC'ing most Athlons, there isn't any thermal-throttling to prevent damage really. Thus, if you have it oc'd too high, and the average temps are continually higher than recommended, you will shorten the life of your CPU. By how much varies with each CPU.

True. You can fry an Athlon CPU pretty easily. However, Intel has had thermal throttling implemented since the early days of the P4. I would assume that an E6600 would be no different. In fact, it's probably even more advanced.

i have an ASUS M2N SLI DELUXE and an AMD Athlon 64 FX 4600 and it runs at 2.8 GHZ.

In my bios I can do AI overclocking by 3, 5, 8, and 10 %

or AI NOS by 3, 5, 8, or 10 %.

I understand you lower the multiplier and increase the fsb, but what about memory, what and where do i change that to, if AI overclocking doesnt already do it.

My cpu temp is at 46 degrees idle with an AI 3% overclock running at 2883mhz

also , i can feel the heat from my 2 8800's down below my cpu and was wondering if that was increasing the heat of my cpu. Anyway, is there any cooling methods to cool my 8800's without taking off the plastic graphics cover or removing the stock fan ?
