It's very easy on P4s. Just raise the RAM speed and keep the divider at 1:1. Once it won't post, reset cmos then try those settings again with more vcore and/or more vdimm. Be very careful with those settings. Overclocking without raising the voltages won't increase your temps very much, but as soon as you add those it your temps can really sky rocket. Do not, under any circumstances, go over 1.6v on the cpu on air. Even then you are looking at dangerously high temps with most air coolers.

Increase by 20mhz at first until you fail to boot the first time, then try 10 or even 5mhz to get your optimal speed. P4s are locked meaning you can't change the multiplier, so your OC is heavily dependant on your RAM. However, if you have shit RAM, you can use a RAM divider which will allow the FSB to run out of sync with the RAM. You will lose a tiny bit of performance vs 1:1, but the pure mhz gain will easily cancel that out.

Google "overclocking p4 guide" or something for more indepth detail and pics if you are confused.



OCing a video card is much easier. I don't know if you have ATI or Nvidia but just grab ATI Tool or the Coolbits registry hack then autodetect your 'max' OC. Test that out with 30 minutes of gaming, then you can go in and raise it more if you want.

ok I have no idea wtf you just said


all I want to know is the basic shit, not "DONT DO THIS< UR PC WILL EXPLODE, WILL GET REALLY HOT"

what settings do I change? i want to get at least 2.8

what are all the settings I need to change. just lable them and and lable beside it what it has to be changed to.

[Akuma]

Step 1: Shut Down your computer
Step 2: Press the power button
Step 4: Get into BIOS by pressing F1/F2/Delete on start up (when your keyboard flashes)
Step 5: This will be different on different motherboards, but find the catagorie that contains the OCing options, go through them all if you don't know which it is.
Step 6: Find the setting that has your RAM speed. Bump it up by 50mhz.
Step 7: Hit F10 then enter.
Step 8a: If the computer boot successfully then you can repeat those steps to add more mhz. Skip to Step 11.
Step 8b: If the computer does not boot, open the case and find the cmos jumper. Put the jumper on the opposite pins and boot up. Repeat steps but bump the vdimm option up one level.
Step 9: Continue to mess around with the mhz and voltage levels. If vdimm seems to have no effect, up the vcore.
Step 10: If you still cannot achieve your desired OC, find the FSB divider option. Inside will be a few options such as 1:1, 5:4, 3:2, and 2:1. If you have really shitty RAM that won't OC at all put it at 3:2. That will give you a good FSB increase with no RAM increase. See step 9.
Step 11: After finding an exceptable OC, download and run prime95. Go to Torture Test and choose the option that puts the most stress on the CPU and run it all night while you are asleep. If you get no errors then you have a stable OC, if you get errors you may experiance some instabilty during heavy CPU load. You may want to go back and turn up your vcore or turn down your OC.



That's a lot harder to explain then it actually is to do...

Bucknub I own a 2.67GHz P4 Northwood CPU. I was able to raise the GHZ to a top speed of 3.20 GHz after raising the core voltage to 1.575 I believe...it was 2 jumps up from stock voltage. ANYWAYS...u can go search in toms hardware for a guide on how to OC. The reason geRV said that about the jumper is cause if u OC too high where u cannot boot stable nuff to get into BIOS to fix it...you need to pull the jumper out (when pc is off of course) and wait a few minutes then re insert the jumper to reset the BIOS, hence taking the OC off. Good luck. Keep in mind if u wanna OC this Chip...u gonna need some ArcticSilver5 and a new HS + Fan. GL!

[Bucknub]

well when i got try to change my CPU speed, the only options I get are "2667" and "4000" and "user defined" hitting + or - doesnt do anyting but change it from 2667 to 4000 I cant get to 2800 if I wanted to, am I doing something wrong?

[Sniped Ur Azz]

Because you need to do the 'User Defined' seletcion. Once you have gone under that u can then modify the mhz...what you need to do is play with the multiplier untill it gives u the GHZ u want. I forget the formula but its something like 20 x Y = MHz Where Y is the multiplier. You can enter ANY number in there on a range from like 100-400 or something not sure. Mine is at 165 (I believe) which makes it 3.20 GHz. Just make sure u are messing with the NUMBERS not the + - keys. Have a look and let me know. In the meantime I will look for that overclocking guide.

[EDIT] Cant find the one I want...but this MAY help http://www.overclock.net/showthread.php?t=1567

Best of luck...gonna see if I can push more outta my CPU and Ram in a bit. Ltr. (Or not if I blow the fucker up)

Question:

When I use coolbits on my GeForce 5700LE 256MB BFG (Overclocked) edition and I try to Auto Detect the 'max' settings...it ALWAYS puts it TOOOO high and my damn card spazzes out and I get MAJOR glitches. I mean...it BUZZES out. So...any ideas?

Just do Manual OC?

[Akuma]

Yup, just manual OC. Start at stock and raise up 20mhz until you get artifacts then lower it down until you get a good stable speed.

[Bucknub]

Well the things you told me to adjust in my BIOS arent adjustable

I can only adjust my CPU speed to either 2667 or 4000mhz

and my Memory Frequenzy to either [auto] [266] [333] or [400mhz]

well thats what gerv said I needed to change at least, and they're unajustable.

[Akuma]

I guess there won't be any overclocking of your CPU then...

[Bucknub]

ASUS P4SA800 is what I have
Overclock Features:
ASUS JumperFree
ASUS C.P.R. (CPU Parameter Recall)
CPU, Memory, and AGP voltage adjustable
SFS (Stepless Frequency Selection) from 100MHz up to 266MHz at 1MHz
increment
Adjustable FSB/DDR ratio, Fixed AGP/PCI frequencies

now should I be able to OC with whats listed thiere?

I also read on some forum while try to research this more

"I have a Pentium 4 2.6GHz OCed to 3.1 with stock cooling and 1.6 VCORE, that was when I had my Asus P4S800 which is a SIS chipset mobo"

SO it can be done, but I dont see these settings, unless Im looking in the wrong place.

[Bucknub]

This is what I see in my BIOS

Memory Frequency looks to be your RAM divider. Leave that how it is for now.

CPU External Frequency is your FSB and that's what you want to change. Take the first number in the fraction and multiply it by 20 to get your final CPU speed. Set it to the number you want... Save and Exit. If it boots, run prime95 and you're good to go.

[Bucknub]

beer: thanks man! +1

Ive OCed it to 2.8ghz for now

but what do u do with prime, I have it, but do I need to dow ith it?

[Akuma]

Go to Option on the top menu bar - Torture Test - In-place Large FFT's


Wait til you go to sleep, or if you are going out for a few hours and just let it run.
