overclocking and CPU voltage - Page 3

post #21 of 25
and dont bother changing your cpu-nb volts, especially at stock frequency. dont bother with raising its volts until you need too.
these members spitting out volts n multis arent going to do any actual help. overclocking is experimenting and passing or failing and experimenting more until you have nothing but failure. but when you do nothing but fail, you accept your last success and smile because you did it right.

There are a few different ways to OC. For people that are new to the art and have an unlocked CPU multiplier the best way is to go slow. Like previously mentioned, the process should follow:

CPU multi bump (one tick at a time)
boot
test (watch temps) = pass
CPU multi bump
boot
test (watch temps) = fail
vcore bump (2 ticks up)
boot
test (watch temps) = pass
CPU multi bump
etc...

Your end result should be a factor of either your target OC or you have reached either your max vcore voltage (1.55v)/max CPU temp threashold (55C). Once you have reached any of these you are done until you get a better cooling solution for your CPU.

This process is the best way for you to get used to how to over clock and learn how your hardware reacts to your OC setting changes. Once you get more accustomed to OC'ing you can change the process around a tad. For instance, picking a vcore setting and work your CPU frequency into that voltage setting. Then move onto working a CPU multi and tweaking it with the FSB freq....trying different configurations that will gain you the best performance for the tasks that you are putting your rig through.

One should never tell a person that is new to OC'ing to use the max vcore setting and any old multi setting, that is just asking for trouble, not teaching the new person how to OC properly and ultimately this kind of advice is going to wind up ruining someone's hardware (and data) someday.
I do agree that a new ocer should learn the basics and understandoicing but I also think that need figures to aim for so they don't try and use damaging voltages and temps. And yes people shouldn suggest high voltage settings for newbies its dangerous.

Ok, that was a bit of a stupid comment but the 1.55v can be considered max safe, so i bet he couldnt have bashed his proc in one try.

I have heard that cpu-nb can help stabilize the OC allowing you to lower the main vcore a notch, atleast you should raise them a bit when raising vcore.

Yeah, if you want to bet on other people's money, sure...no problem. I, on the other hand, prefer to teach someone how to really OC and not just guess, but that is just me. Most likely you wouldn't have blown up his CPU but it was really too high a vcore for a 4.0Ghz OC on that chip.

Increasing the NB helps to stabilize several things, but not typically the CPU OC....it does on the other hand help to stabilize OC'd memory.....or if you are running all 4 dimms populated at a speed higher than the supported 1333Mhz.

Well now that all that is out of the way lets get back to helping the OP with his problems.

There is a really good guide on here that i used but cannot find it could someone post a link up of them for OP to use.

This is a link for the 955 oc thread, have a look and see what other people have achieved.
http://www.overclock.net/amd-cpus/49...oc-thread.html

EDIT: Found them here they are.

http://www.overclock.net/amd-general...ing-guide.html

Have a good read of those and you should be golden to start. Have fun.
