Intel P4 1.4GHz Willamette Socket 423 FSB400MHz - help me OC it!

[duble]

I need some help.

I am a first time overclocker. As I am about to build a new system I thought it would be a good chance to try some overclocking on my old beast.

I am having some trouble finding information on my processor, I have requested some information from the Intel Museum and hopefully that will give me all the standard values that my processor is rated for.

My CPU is a Intel Pentium 4 1.4GHz Willamette Socket 423 FSB400MHz

I am new to overclocking and have read bits and pieces. What programs do I need? What system data do I need? Has anyone OC'd this CPU?

Any help would be really appreciated.

Hello and :welcome: to the Forums duble,

Please specify your motherboard make and model. The motherboard is instrumental in the overclock as many OEM boards do not allow for such tweaking.

Sandra 2005 tells me its an:

Manufacturer - Elitegroup (ECS)
Model - P4X226-8233
Chipset - VIA P4X226/A

Also lists:
Chipset1
Model - Elitegroup computer sys VT8753 Apollo P4X226 System Controller

But the label on the board says:

P4VXAS

My system is old and its specs are as follows:

Purchased November 2001

Intel P4 1.4GHz Willamette Socket 423 FSB400MHz (100x4)
ECS P4VXAS mobo socket 423
512MB SDRAM (2x256MB 168pin PC133MHz)
40 gig hard drive
Nvidia GeForce 2 MX200 64MB
Sony DVD-ROM
Unknown CD burner ROM (not working)
250W PSU

okay, ive been looking around and have got the info i need (i think):

Intel Pentium 4 1.4GHz Willamette Socket 423 FSB400MHz Standard settings:

SiSoftware Sandra:

Speed - 1.4Ghz
FSB - 4x100 (400MHz)
Core voltage - 1.750V

SiSoftware Sandra sensors (current values):

CPU voltage - 1.73V
CPU temp - 30oC

I have acquired:

Prime95 for stabilty testing
SandraLite 2005 for tests/benchmarking
PC Mark 04 for tests/benchmarking
PC Wizard for testing/benchmarking
CPU-Z
Speedfan for 4.25 beta for adjusting fan speeds, test V's and temps

I understand now that it is simply a matter of multiplying the FSB speed by its multiplier to get a certain speed. This means the multiplier in BIOS should be 14...I havent checked yet but 100MHz x 14 = 1400Mhz/1.4GHz. (The FSB is 400MHz but its actually 100MHz x 4 - Apparently thats how Intel set it?)

Now i hafta check that I can change those values in BIOS, if not i'll need 2 resort 2 jumpers or OC'n software.

What else do i need?

What is recommended - changing the FSB or the multiplier?
Does it make any difference which one you change (ie-the only thing that matters is the final value, not how u get it)?

Why/when would I have to change the Core voltage?

How much can I raise the FSB by at a time? Whats too much?

Thanks

I just went int BIOS to scope it out.

Here's what it looks like:

- Advanced Chipset Features
- DRAM Clock/Drive Control
Current FSB Frequency - 100MHz

This value is unchangable as I cannot select it. How do I unlock it?

- Frequency/Voltage Control
CPU clock ratio - 10X

I am able to change this value.

From what was said before that means the speed should equate to 1000Mhz or 1.0GHz, but all my programs tell me i'm running at 1.4GHz...why is this?

[duble]

Just went into BIOS again to double check everything.

The multiplier can be changed...i can set it to any value, but i haven't yet, so i don't know if it does make a difference.

The value that is locked is the FSB speed, its locked at 100Mhz and i cannot see an auto/manual option anywhere in BIOS to unlock it - which makes me think I have to change a jumper on the board, or its locked permanently.

But the good news is the multiplier value can be changed - i just hope it actually changes the CPU speed.

I still can't understand why the multiplier is set at 10, it should be 14!

No, the multiplier is locked on the processor. Changing it in the BIOS won't do anything. Sounds like you have a motherboard that does not allow overclocking. However, before giving up completely, try downloading and using a free program called softFSB.

[duble]

no good, im running XP and softFSB doesn't work on it, thanks anyways...guess this old beast jus dont wanna go no faster

Two other programs you might try are clockgen or CPUcool/cpufsb.

ECS is pretty poor and the via P4X266 chipset pretty limited, but I would think you could change the FSB in bios. I would recommend downloading the user's guide for your motherboard and verfying it cannot alter FSB before resorting to software means.
