Overclocking a P4 3.2c

[psuc41]

Anyone got any links to any sites that have guides on overclocking a P4 3.2c processor, I am using a P4P800 Deluxe "Springdale" motherboard. I posted this in the overclocking forum but it looks like no one looks at that section.

Just do what you do for all processors.

what do you think about that motherboard.... i was looking at getting that one

Get the Abit IC7 Max 3 instead, definitely the better premium board. I had hell w/ the Asus P4P800 Deluxe for months before exchanging it.

Okay so has anyone got any links in general for overclocking P4 processors then?

what is there to know? you increase the FSB, that's all you can do.

There is a bit more to it than that...

Try this link:

I personally don't OC anymore. I got my P4 2.6 up to 3.4 stable, but I had issues with my Audigy making feedback noises in UT2003. Once I got that under control I was only at 3.0, which wasn't noticable except in PCMark04. So, I run stock now.

1) enter the BIOS by clicking Delete at Bootup
2) locate AGP/PCI lock and "fix it" at 66/33
3) understand that 3.2ghz = 3200mhz = 16x200FSB
4) undestand that at default CPU and Memory run at 1:1 ratio => 200FSB: 200mhz memory
5) 200mhz memory is DDR so running dual channel at 200x 2 = 400mhz
6) so Adjust the FSB setting:

ie. Example 1: + 1FSB => 1x16multiplier = 16mhz increase in clock speed (201 total FSB)
Memory must be running at 201mhz (or 402 effective)
Example 2: + 17FSB =>17x16multiplier = 272mhz increase in clock speed (217 total FSB)
Memory must be running at 217mhz (or 433 effective)

Possible problems:

1) Memory not being able to handle the proportional increase in FSB
=> Solution: lower the CPU:RaM ratio from 1:1 to 5:4 or 3:2

Explanation:

200FSB: 200mhz (400mhz effective) memory => 1:1 ratio

So if you are running 217FSB and your memory cannot handle 217mhz increase apply:
a) 5:4 ratio => 217FSB: 174mhz (388 effective) b) 3:2 ratio => 217FSB:145mhz (290 effective)

2) The cpu will eventually hit a wall at a certain FSB even if you adjust the memory ratios at which point:

your cpu will freeze, crash, hang, etc.

Solution: either decrease the FSB to a lower stable setting, or increase the CPU voltage to 1.65Volts at most (my recommendation)

Similarly if your ram is overclockable you can increase the voltage on it up to 2.8V (and up to 3.1 if you have GEIL) to run 1:1 as high as possible. You could also decrease the latency timings on the RAM (ie. from 2-3-3-6 to 2.5-4-4-8), but this reduces performance

So in conclusion:

Find the HIGHEST FSB you can go, with cpu voltage as low as possible (lower than 1.65 at most), and memory running AS HIGH AS possible, while having THE LOWEST latency possible.

Tools to test stability: Prime95, Winmemtest, run several loops of 3dmark01 or 3dmark03
Tools to test CPU and memory speeds and voltage: Motherboard Monitor 5.0 (MMB5), CPU-Z, WCPUID3.1a, SiSoftwareSandra, ASUS PCProbe

If you cannot find any of these I will post links to them if you wish. If you have any further questions, let us know.
