Is Overclocking About Increasing FSB Only?

[slim142]

Hi

Well my question is the one in the subject. And could you guys explain me about the RAS, CAS latency and all that stuff. Also when do you know when to add voltage. And how to know if you have to change the multiplier or not because the only thing I do to overclock is add mhz to the FSB. Thats it. Im right?

thats the easy way for overclocking, it will get you a ways but not to the best atainable overclock.

in some cases the fsb is a limiting factor in this case people mess with the multipier to have higher clocks
in more cases tho its the ram clock which normaly scales somewhat with the fsb that is ajusted

adding voltage is a way to pull more clocks out, make it go faster, you do it when nothing else will make it go faster and feel that it wont destroy your cpu from tempatures

ras cas and others relate to ram timeings, i think ill leave somebody else to explain that too you tho

Im overclocking my Pentium III since im getting Conroe later this month. So my FSB is now in 138mhz with 1.45Ghz (My PIII is a Tualatin 1.4Ghz)
But I read an article where they overclocked a celeron and they could overclock it by 50%!!!!!!!!! but first they increased the voltage to 1.6v (default was 1.45v) should I do that too before going to 140mhz or 142mhz FSB?

Thanks

that really helped me alot. I was going to put my tualy of 1.45v to 1.50v but I understand what you said about overheating so ill keep it safe.

Thanks again

Yes don't screw around with the voltages until necessary. If you are happy with the overclock you can attain on stock voltages then that's great. If you reach a point where the system is instable but you want to keep overclocking then increase the voltages on vcore and ram until it's stable again... little steps.

Thanks waylander
now how do i increase the voltage of the ram and when should I do it? because i never learn a lot about modifying the ram things

A good idea when overclocking for the highest numbers, is to lower the multiplier, raise the timings, lower the HTT multiplier and increase the FSB till errors, then raise mem voltage, and raise some more... this will be close to the maximum your memory in that configuration can go...
Then, you will know at what MHz you need to need to increase mem voltage for stablity...
