Noob OC questions

[Falcon2k]

From all i've learned so far. To OC, you increase the fsb and your CPU multiplier (if you can). Where the fsb x CPU multipler is the speed your comp runs at. But increasing the fsb increases the amount of heat the cpu produces and without adequate cooling, the rig will crash. Also, the better the ram, the higher your fsb can go.

What i dont get is the voltage. ppl say to increase the voltage, but my mobo dosnt seem to allow me to do that. (mine seems to be unoverclockable apparently). Does the mobo automatically increase the voltage to the CPU depending how much it needs or do we need to increase it ourselves?

Also, just to clarify, the procedure to overclock is to turn on comp, get into bios, turn up the fsb, restart, try to get into windows, if it dosnt crash after a while, go back to bios, up the fsb again, restart, if it dosnt crash, go back to bios and up until it does crash?

How do you manage to permanently physically damage the CPU from doing this?

What is the maximum temp your CPU/system should go up to while being safe? I might try to OC my 2.4C processor with an Asus P4P800 mobo. What's the maximum operating temperature i should go up to?

you have to increase the voltage. but in the P4's case, most of them go up to a certain speed and then even with voltage increase, it goes up by a little only. it's like hitting a brick wall.
i use Prime95 to test CPU stability

 

[Falcon2k]

So the cycle is:

Get in bios --> up fsb --> run Prime95 --> crash --> get into bios --> Lower fsb --> run prime 95

Get in bios --> up fsb --> run Prime95 --> stable --> get into bios --> increase fsb --> run prime 95

Repeat until system is at it's highest stable fsb?

How much do u think my 2.4C with a P4P800 mobo and 2x Samsung DDR400 512mb ram running dual channel will go up to max with stock cooling?

What fsb should i go up to with what voltage?

I havent got the stuff yet, but i dont wanna fry my CPU the moment i get it.

Can anyone point me to a Dummy's guide to Overclocking on the internet?

Get your system as fast as you can without bumping the voltage. If you do bump voltage do so very carefully. Overclocking is a pretty safe endeavor until you start tweaking voltage.

Does the AGP voltage affect OCing? Is it dangerous to change the AGP or DIMM voltage?

Also, is there an advantage to 1:1 vs 5:4 ratios of OCing? And whats more important, low RAM timings or high FSB?

 

[Shimmishim]

there's a trade off

i did a test and i found that running 200 mhz @ 2-2-2-6 is almost the same as 208 @ 2-3-3-6

other's will disagree

some aps like seti@home supposedly like the higher fsb... so does 3dmark2k1


with the 1:1 and 5:4 dividers here's the deal with those

if you are running 250 mhz fsb 1:1 then WOW... THAT'S GREAT... but most ram can't handle 250 mhz

so people use the 5:4 divider which gives you 200 mhz on your ram...

from what people have posted, the performance hit isn't HUGE but of course running 1:1 is always going to be better..

can't wait for ocz to release their pc4000 or pc4200!!!

for the fsb x multiplier thing I have an amd xp 1700+ 166fsb and 12 multiplier that is 1992 so why does my comp say 2000 htz?

answer 1) maybe its rounding
answer 2) maybe its not exactly 166FSB, maybe its 166.3 or the like.

oOo that would make sense thanks
