few question about overclocking

post #1 of 9
Thread Starter 
Alright ,i m completely new to overclocking . I just have few questions to ask (though i have read many guides but still my doubts are not completely clear)
1 - When someone overclock the cpu wrong , then pc shut off automatically to prevent instability or give random BSOD when temperature is too high, then why people still get their pc part damaged . Say , out of 100 , how many do damage their pc?
2 - Do most people damage their pc because of setting voltage too high or not having proper cooling system or both ?
3 - Do extend of overclocking depend on quality of motherboard( assuming all are z68) ?
4 - I have read that the best setting for someone with same pc configuration of his friend may not be best for him . does that suggests that it may even turn disasterous to him??
5 - For a person completely new to overclocking what will the starting cpu multiplier you should recommand assuming he has i5 2500k?
6 - Can i start overclocking with lowest most cpu core voltage to be completely safe and then increase it accordingly? Say for 4 ghz for i5 2500k, i start with voltage 1.18 or less?


Hope my doubts will be removed . AND thanks for your time
HAPPY OVERCLOCKING

1. Experienced overclockers - 3/100. Inexperienced overclockers - 60/100
2. Each.
3. Yes.
4. Maybe, although OC that is stable for someone is really unlikely to burn another person's PC, if the hardware is identical
5. No idea, I use AMD tongue.gif
6. No, you have to start with the Default voltage. Lowest is not enough even for stock clocks.

1. Its kinda dificult to actually do SERIOUS damage to a cpu. Too much protection. (A member here is actually TRYING to do it. Others have failed. LOOK HERE)
2. Degradation is more likely with high voltages and bad cooling. Catastrophic damage is unlikely for CPUs. But for motherboards is likely if OCing is done on the wrong board.
3. If you don't have a good board then overclock at your own peril. You NEED a good board.
4. Disasterous-probably not. But it won't be the same for sure.
5. Dunno...AMD for life. (maybe)
6. Yep!

Thanks . Reped both of you . But it seems like your last answers contradict each other...

1. If you are overclocking and keeping an eye on your temps than you should never have a shut down/bsod because of temps. The shut down/bsod would be more because of not enough voltage to keep the cpu stable. That's why it is important to start low and work your way up when overclocking.

2. Both. Most people that damage there part either have no idea what there doing and will use way to much voltage. Or trying to push a cpu/gpu to unrealistic overclocks because they read somewhere that some guy did it without good cooling.

3. Yes you absolutely need a good MB. Good mb's have more capacitors and vrm to deliver more consistent power to the cpu. I see it time and time again someone trying to overclock at OCN and have some crazy voltages on a $50 mb not designed for overclocking.

4. Never use someone settings!! Every computer doesn't matter if you have the same hardware will not work together as another computer with the same parts.

5. I would not start higher than whatever turbo is. So if the cpu stock is 3.3ghz and the turbo bumps it to 3.7 << that would be my starting point for my overclocking. From there work your way up.

6.When starting an overclock leave voltage at stock. I would first see if the turbo is stable at stock voltage. From there bump the multi 1 until it becomes unstable at stock voltage. When it becomes unstable from voltage bump voltage up a touch like .0250. So say stock voltage is 1.200 I would bump it to 1.225 then 1.250 and so on until the cpu is stable again and so on.

Gl hope this helps

Thankyou very much . This was all i needed to clear my doubts. Repped you . smile.gif
edit - what will happen if i start below the stock voltage(undervolting while overclocking)

You could start of with lower voltage but chances are your cpu will become unstable and you will get random bsod. wink.gif

Alright . I think i got it . I will just start overclocking at stock voltage with cpu multiplier 37 to be completely safe . will run a couple of stress test and monitor the temperature . If the temperature is fine i will increase the multiplier till i get a BSOD . I think at that point i will stop because i dont wanna touch the voltage . Will go higher after gaining enough confidence . thumb.gif
