- Overclocking questions -

I have a Dell Vostro 1400 with 1.6GHz T5470. I'm interested in overclocking the CPU only. Leave the GPU untouched.

What is the safe clock speed to which I should overclock to? I've read somewhere that it can be easily overclocked to 2.4GHz, with a subsequent raise in temperature of 10C. Mine right now idles at 36C, and goes to 59C under 100% load.

Also, since this is my first time overclocking, i would like to know if I can overclock it with software (recommend me some) or in bios. Is the multiplier locked?

And, can someone explain me what does "core clock" and "memory clock" in RivaTuner represent? Is it strictly related to GPU? Can I use it to overclock CPU or RAM?

PS: Does anyone know the PLL number for Vostro 1400 (1.6GHz, T5470)? Also, whats a safe overclock speed for this laptop?

 

To OC the CPU, you need to know your motherboard's PLL no.... (you will have to open the laptop, and look for the cpu clock generator chip, or hunt around for the PLL on google, or just ask someone who has the exact model as yours and has already OCed it successfully)

You can use clockgen, setfsb, cpucool....

The multiplier is locked, you can OC your FSB, but that will also increase the frequency of the GPU and RAM....and I doubt you will be able to raise the FSB in the BIOS....Since it is OEM, so most options will be locked..!!

I don't think RivaTuner has got anything to do with the CPU or FSB....

 

multiplier is locked.

If your warranty has expired just buy a new one. You will end up buying a new one anyway after your 2.4ghz T5450 burns out

 

Actually, my standard 1 year warranty will be up next month.
Hence, I wanna OC now so if something goes terribly wrong, I can always salvage something using the warranty.

PS: I know OCing voids the warranty and what not. But, you can always try.

 

Ethically, that isnt what the warranty is for but anyway

If you overclock now, it will most likely die after the warranty period. I wouldnt go all the way to 2.4ghz, maybe 2.2ghz max. Keep a close eye on the temps.

 

The Vostro 1400 isn't a very powerful machine, so it will be hard for you to get to 933MHz FSB or above, which would give you a clock speed of ~1.9GHz....and you would also need to have DDR-800 ram installed to have a good and efficient OC, or you will suffer from BSODs, due to the OCing of the DDR-667 memory, which isn't a good idea in the 1st place..!!
Its better you just swap the CPU for a T8300 or something higher, after the warranty expires....

 

2.13Ghz would mean pushing FSB to 1066Mhz could cause some issues. But any way start with little amounts and test for stability. Chips even the same model have different OC ability so you need to discover your's limits.

Swapping in a T8300 in is the way to go. If you think expensive? Less than MoBo and CPU from OC.

 

Why T8300? Is it the best price/performance mobile chip in market right now, similar to how Q6660 is for desktop? How about T8100? $45 cheaper with 0.4GHz speed less .. which can be salvaged by overclocking ..

Also, how much can a T8300 be overclocked? I know it varies, but what's the average estimate?

 

May i ask why you are so keen on overclocking? For what purpose will you use it for?

 

I'm sure you too were that curious when you first started overclocking
Knowledge is wealth.

 

If you OC the T8300 by increasing the FSB to 233MHz - you should get a clock speed of about ~2.8GHz....and if to 266MHz - a clock speed of 3.0+ GHz....

Also you would need PC2-6400 RAM and need to keep an eye on the GPU as well....!!

If you are so keen on OCing, try out a X9000 ES....play around with OCing, and fry that notebook like a french omlette..

 

I like mine half fry

 

nvm, i thought you were the original poster.
