Overclocking..

[timmcat]

I dont really need to do it, but curiosity is getting the better of me.

My system has a P4 2.53 processor. How do I overclock it? I dont want to 'go mad', but a bit of extra free power would be nice.

The FSB in the BIOS is running at 133 MHZ.. if I try and alter it, it will only let me reduce, not increase it.

The BIOS is Award 6.00 PG. Mobo is MSI 6533.

Any suggestions?

Tim,

If your Motherboard is the Straight MS-6533 (there are several versions of the MS-6533) go to page 3-27 of your motherboard manual. There you can find the settings:

CPU Clock Ratio
End users can overclock the processor by specifying the CPU ratio (clock multiplier) in this field.

Auto Detect DIMM/PCI Clk
This option allows you to enable/disable the feature of auto detecting the clock frequency of the installed DIMM/PCI bus. The settings are: Enabled, Disabled.

CPU Host/SDRAM/PCI Clock
This setting controls the clock speed of the CPU Host (FSB)/SDRAM memory bus/PCI bus on the motherboard.

Before you start overclocking you must be 100% Comfortable with the possibility that you could turn your mobo and CPU in to an expensive Key Chain! Make sure you have good cooling for your CPU too.

If you are still having problems overclocking your FSB try the:

MSI Forums for their headquaters in Taiwan (http://www.msi.com.tw/program/e_service/forum/main.php)

Two of the moderators I would contact there are Assaf (http://www.msi.com.tw/program/e_service/forum/members.php?mode=profile&userid=223&boardid=0) (recently retired as a moderator but still posts regularly) and Wonkanoby (http://www.msi.com.tw/program/e_service/forum/members.php?mode=profile&userid=134&boardid=0).

If you still need help, you can contact me there too, Deathstalker (http://www.msi.com.tw/program/e_service/forum/members.php?mode=profile&userid=48&boardid=0), I am the Moderator for nForce/SiS/AMD Socket A Motherboard Forum and Multimedia Forum. I can forward your problem directly to the MSI BIOS Team.

Aren't the multipliers locked in the latest P4's? Therefore the only thing you can adjust is the fsb, this of course will affect memory, agp slots etc, check out overclockers.com or .net.

spannersatcx,

Intel locks their processors. The only way to overclock them is by raising the FSB. That is why we were looking at unlocking the:

CPU Host/SDRAM/PCI Clock
This setting controls the clock speed of the CPU Host (FSB)/SDRAM memory bus/PCI bus on the motherboard.

Right now his mobo only offers lower FSB Clock speeds. We are working on getting him the speeds above 133Mhz (266DDR)

Take Care,

Richard
