Please help new to overclocking

[trusnoop]

I tried to overclock but nothing happened. My cpu is a P III 600EB.
Normal setting would be 4.5x133 = 600mhz, but when i had 5.0x the cpu was still at 600.
This mobo is overclockble cause at Tom's Hardware there is a mobo review for this mobo.
Please tell me what settings to apply for cpu and memory (if possible agp too)


Settings for the cpu:
ClkGen Spread Spectrum: Enabled/Disabled>>>> This must be disabled to overclock (says in the manual).
CPU Holt/PCI Clock (MHz): Auto
87.5/29.2
85/28.3
200/40
190/38
180/36
171/34.2
166/33.2
162/32.4
159/31.8
157/31.4
154/30.8
etc.
CPU Ratio selection: 4.0x
4.5x
5.0x
5.5x
etc.
CPU In Order Queue: 4-Level
1-Level

Settings for the ram:
Set Sdram timing by SPD: Enabled/Disabled
SDram cas latency: 2/3
Dram Integrity Mode: Disable/ECC

Settings for AGP:
AGP Comp. Driving: Auto/Manual
Manual AGP Comp. Driving: 5a, 5b, etc.

thanks

In order to overclock you would need to increase the frontside bus (FSB). You say you already have it at 133MHz. You would need to grab some PC150 SDRAM and hope your motherboard and peripherals don't mind being overclocked over 133. I don't know if that CPU is very overclockable. It doesn't sound like it.

as Raystonn said, odds aren't in your favor.
133mhz already, you'll be limited by your motherboard.
your multiplier is locked at 4.5, it can't be changed.
grab some pc150 and see how it'll do.
if you have PC133 CAS 2 now, you can set the CAS to 3 and you may get 150 out of it...

Independant thought is good.
It won't hurt for long.

well, if you have some values of the order of 145 MHz FSB and 36 MHz PCI try it. 154 seems a lot higher, since you cant change the multiplier it will attempt to run at 693 which is a bit higher especially when the FSB is out of limits. you have a PC133 RAM that most probaely wont work at this high speed, but 145 is quite ok for it to run, just in case it doesnt you can always go for a PC150.

see if that board has manual settings (by jumper) probably the soft settings take effect at bootup and might have been locked by some jumper.

and the CPU ratio in the BIOS settings will not have any effect since the multiplier is programmed internally.
