question about OCing...

1) I plan to OC my 3400+ Clawhammer to the 2.4 speed of the Newcastle version. My question is, I'm going to use this rig until 5 year without upgrading the CPU. If I OC from a 2.2 to a 2.4, how long will the CPU last?

2) As I read the Overclocking Guide, the guide said that it is better to raise the FSB and lower than Multiplier instead of raising the Mul and lower the FSB. Well, after I do that, how much CPU voltage should I increase to get it to stable? The default is 1.5v .

3) Do I increase the CPU voltage first, and then increase the FSB/lower Multi. Or should I do the FSB/Mul first, and then increase the voltage?

Thanks and Happy New Year!

Currently Running Default:

CPU: 203x11 @ 2233
Ram: Corsair Value Select one running at 2.5 Cas: 3:3:8

read the other forums.
1 idk, depends on the cooling solution and how much u use it a day. if you plan to use it a lot, upgrade the cooler.
2 yes the higher the fsb, the better. i dont kbnow, all systems are different. raise it about .01 till it is stable.
3 voltage first i believe(i'm not sure, someone correct me if im wrong)

Actually, it's the other way around.

First you try to incresase performance. If it fails, up a notch on vcore or other part of PC.

I'm running a 3000+ ( 1800mhz ) and didn't need to up vcore until reaching almost 2400mhz...
You only need to up vcore if changing fsb up, and multipliers down, overall mhz speed is raised.

StormGiant has it.

Increasing the voltage will increase energy lost to heat, which in turn causes additional stress to the processor. Bumping up the voltage is a last-resort after trying and failing to improve performance through resetting the multiplier and FSB.

Alright thanks guys.

1) So that mean when I up/down the FSB/Mult. If it reach 2400mhz as I wanted and it run stable with the default CPU voltage, then I'll leave it like that. If it unstable, then I need to increase the Voltage right?

2) Well what about changing Memory timing and stuff? Do I really need to change the Memory timing as the CPU changed?

1) yep, that is basically it...

2) If you raise the sped of the memory, you may have to up the voltage and/or relax the timings a bit to keep it stable. You can run the memory on a divider and keep the memory speed from changing much and still be abke to OC the CPU.

I don't think my mobo has memory divider or not (it doesn't show up in Everest). Anyway, if I raise my 3400+ Claw to 2.4ghz, what timing should I input in the memory?

Currently it run at 2.5CAS 3:3:8 .
