Hooray for first OC!

Well, I decided I wanted to get some more life out of my 2.5 GHz Celeron (Northwood core) before I dumped it for an Athlon 64 3700+ Sandy, and decided to OC it. I've got it at 2.75 GHz, with a 110MHz FSB and a 25x Multiplier (!). I think I'm gonna up the FSB to 120, giving me 3 GHz flat, and see if it's stable... I know it's not anything major, but it did raise my 3DMark03 score by 270 marks.
I'll post CPUZ verification in a little bit, gotta get the internet working on it again... I'm on the laptop right now.

That's the way.
That's what this is all about.

Prime95 is used in the overclocking community for testing system stability. If you can run your system for 24 hours on blend then you are running a very stable system and overclock.

Your Celeron "D" is a Prescott Processor. Download:

CPU-Z

and run it. What is the Processor Stepping? Three hours running prime95 and 56C is not a bad showing for a Prescott and I would think that you are using the D(0) stepping which is a cooler stepping than the C(0) stepping.

Prescott processors dissapate more than 50 Watts above a Northwood processor so one expects a higher thermal envelope. As a matter of a fact, Intel uses a technique called "Strained Silicon Process" which not only improves the transistor performance but also allows a higher thermal envelope. You have no worry running that processor at 56C full load.

As a matter of a fact, Pentium 4E (Prescott) processors run close to that level on idle (stock heatsink/fan) due to their four times larger cache.
