Can someone explain this OC result with Celeron (I am a n00b)

I have a Celeron D 478, not sure which model but it's 2394MHz in CPU-Z.

My mobo's not really an overclocker I'm sure, It's a Foxconn 651M03, but it does have cpu clok adjustment from 133 up to at least 300 I'm sure.

I know it sounds silly, but I tried to OC my CPU clock by 1. Just 1. And it didn't work. I POSTed, and got into windows, but when booted up CPU-Z says my CPU speed is like 1800MHz! It decreased.

At defualt it's like this:

Core 2394.1
Multiplier 18x
Bus 133
Rated FSB 532

After changing my CPU clock to 134, the result is something like this in CPU-Z:

Core 1800
Multiplier 10x
Bus 100
Rated FSB can't remember but ~ 400 I think.

What am I missing?

By the way reasonn for just 1mhz OC is that my cpu's already 65c at idle, I think Its heatsink is dust clogged and maybe badly seated, I hust wanted to see it change a little bit, just for fun.

What I think happened is your bios reseted. It probably couldn't handle the 1MHz increase.

Also, after you increased the bus to 134, your multiplier of 10x can not be correct if your cpu is running at 1800MHz. This is because 10 x 100 = 1000MHz, not 1800MHz.

I guess the multiplier not being 10 is a point, I'll have to try again to see what the result is properly, I never wrote it down last time.

I don't know about the BIOS resetting, nothing else seemed to have changed, but I will double check that too. Why couldn't it handle a 1MHz increase?

Could be one of many problems. I'd suspect ram. Set it to 1:1 fsb to ram ratio.

I would not bother trying to overclock that Celeron chip by even 1MHz. It's pointless to overclock those chips. If I were you, I'd maybe keep the hard drive and any other CD/DVD drives you have... Pick up a new case, motherboard, CPU, faster RAM, and PSU. Even a cheap C2D Conroe would kill your Celeron right out of the box. A decent board can be bought for $100 or even less. Only do this if you're actually going to be using the processing power that you gain from upgrading. I upgraded last month from a Pentium D 2.8GHz to the new Wolfdale E8400 with a $90 Gigabyte P35-DS3L motherboard, and with the same memory and graphics card, this thing blows my Pentium D system out of town. It's like comparing a PSOne to a 360. That's the performance I gained.

I'm already planning a new system, I just don't have enough money. I' m basically just messing around for a laugh. I don't really expect much of a boost or anything.
