cpu upgrade on centrino 2

i currently have a t series t9400, and im wondering if it is possible to upgrade to a p series cpu. p9500 or p9600.

also btw, what is the fastest p series cpu at this moment?

 

The fastest P-Series processor is currently the P9600. Since you already have a T9400, you should have a Socket P motherboard with a 45-Series chipset, meaning that you can use any of the usual Socket P processors through the T9800. Assuming you have BIOS support, this includes the P9500 and the P9600.

 

Samll question - if you already have a T9400 I doubt an upgrade will be worth it.

The increase in performance won't be too large.

It could be a waste of money, unless you specifically know your CPU to bottleneck something.

 

From the OP's sig. the problem is not performance. He has issues with the battery life. That's why he is trying to upgrade to P series.

 

thanks for clarifying my position ramgen, u r completely right. im just wondering how much of a difference 10watts can do. my laptop currently lasts around 3+ hours, and i am hoping to get to 5-6 hours with this type of upgrade. is it plausible or am i shooting for the moon here?

 

Oh, OK.
Question - its 35Watts vs. 25Watts, isn't it?
I doubt the difference will be that large.

If battery life is seriously bad - bad battery?
Heat: Clean vents? Good fan?

 

It won't do much unless you're consistently running the processor at a significant load. The 35W and 25W is the theoretical heat output at full load. If your machine is mostly running at idle or close to idle, there will still be some power savings, but they will be small.

 

And tomorow I shall be able to levitate

That kind of increase is impossible.

Someone asked that question in here before.
The consent was that you would possibly get 30-40 minutes more max I believe.

By the way - 3hours, is that on max powersaving?
For your laptop that's very good.
(looking at power)

 

I think you'll be quite lucky to get more than half an hour more battery life by changing to a P-series processor.

 

Checking out CPU World figures, the difference between the 2 CPUs are:
Max Power Dissipation: 10W (57->47)
Min Power Dissipation: 1W (4->3)
TDP: 10W (35->25)

So, under load, you could probably get an extra 30-45 min by switching to a P-series CPU. When idling, (what you do when power saving, right?) you may get 5 min since the difference is minimal.

 

thanks for the replies, i use my own settings, but i do turn off most hardware that i dont use like bluetooth and dvd drive. as for software, i have undervolting and vista battery saver. if i turn off wireless, i get more but who uses a laptop without internet?

i guess the only way to get better battery life is if i chose intel graphics card rather than the ATI.

notyou, where did u get those figures?
