Overclocking

ProjectMayhem · 08-27-2004, 12:26 PM

I've taken necessary cooling precautions, but I'm not sure about how to go about overclocking the processor. I'm assuming you change the FSB speed in the BIOS, but whats a safe speed to change it to? i currently am running a 2500+, the actual clockspeed i believe is 1.83 GHz. I'd like to overclock it so that it runs about equal to a 3200+. Can anyone help?

I have a 2500+ at 3200+ so I know how to do it to 3200 speeds easily (as long as nothing else inside complains

)

Go into bios, the FSB should be at 333 (or 1 mhz around it) right now. Change it to 400 and your set. Now also, you do have PC-3200 ram right? (just to make sure it can handle 400 fsb without any problem)

i wish i had money to buy a 2500+...my ****ty comp is on a 1400+ (running really really really well)...oh well, hell my comp is so old, the motherboard doesnt support DDR RAM

lol...junbo, can you list what cooling stuff or whatever i would need to get a 2500+ to a 3200+? and how much it would cost

I suggest a water cooling system...but thats just me

Im sorry....i just find that f****** hilarious.

All you would need is a decent heat sink and fan. Jonbo has some insane heat sink that bolts to his mobo and a fan that, if ran on high, will cause you to throw it out of the window because of the noise.

yea, same, i actually have the heatsink made for the 3200+, it was the same price....it also has the fan and bolts to the motherboard, plus i have a PCI slot double fan installed, as well as 2 external fans on the side of my case, and in the back. I think i'm alright on cooling. I never notice the noise since i always have music playing

Yes, yes I do. And I don't want to get rid of them when I do the next major upgrade in the fall/winter but by then I can find another insane heatsink for my A64. And btw..here's some images of my heatsink and fan (its not my own taken but its the same thing)

(thats the same mobo I have but the northbridge heatsink is different for me)

And the fan I have (with a fan controller obviously like Hero2 said)
Image shown has a grill on it, mine doesnt for obvious reasons

And just a comparision shot of a puny 80mm fan vs. Tornado 92mm (that i have)

Well the true FSB is 166x2 so if your BIOS shows the real FSB you have to increase it to 200 so it would get a 400 FSB. Alos before saving this setting, lower your CPU multiplier. It might be that your CPU might not overclock just as good as Jonobo's CPU. So now your CPU works at 166x##. Changing the FSB you will get 200x## but it might be too much, and you won't even be able to boot the system, and have to wait for it many hours until the CPU is at room temperature and can hold on at boot until you change the BIOS (I know it hapened to me)
After a few tests where you can see the RAM is stable at the speed slowly increase the CPU multiplier and retest until you reach the ceeling of it's speed on current cooling and voltage. From here on you're on your own if you try to increase voltage and other stuff.

I have a 2500 Gimpy

And to quiet: As long as his isn't a locked barton (on hte multiplier) he can change it. I know about a year ago or so AMD started locking the multipliers on them (unfortunately mine was locked too) so he may or may not be able to mess with it too. And also, I spaced on the 166/200 thing. I'm used to thinking 333/400 and didn't think about the bios possibly showing it that way.
