should i downgrade from a T9550 to P8600?

I don't need all the power of the T9550 and would rather have a cooler and longer lasting laptop with the P8600. All I do is general web browsing, watching 720p bluray rips.

How much can I expect to sell the T9550 and buy a P8600 for?

 

Use eBay to judge the selling and buying price.

cheers ...

 

undervolting will let it run cooler, you can also underclock.

thanks, seems like T9550 are going for $200 and P8600 for $120.

 

i'm going to try this out first. if not, i don't think i'll miss the extra 3mb cache since i've been used to the E2160 1MB cache CPU the last 2 years and find it quite suitable.

 

The P8600 will be more than enough for your uses, so you will be fine selling your T9550.

 

does underclocking require any soldering?

 

No, its all in software.

But i wouldnt recommend underclocking. it will slow it down. undervolting should be effective enough. try that first. Undervolting Guide.

 

It is a worthfile downgrade I think. Saves notebook life and power with using lower processor. Very smart indeed. Energy cost saving overcomes in cost saving for the cost of this downgrade. Very green.

 

If you don't want the hassle of selling your old processor and replacing it in your notebook, just use RMCLOCK to:

1. undervolt
2. disable higher multipliers

 

Hi Tracer,

Just out of curiosity what is your Laptop!?!?

G!

 

You don't even need to disable the higher multipliers. If you don't need that much CPU power, it will automatically lower the multiplier to the minimum. My processor runs at 1.00GHz most of the time, but when I need it, it will switch to 1.83GHz automatically.

 

i have a Dell Studio 1555. that reminds me, time to place the specs in my sig

 

You can undervolt a T9550 to use less voltage than a stock P8600, without having to swap the actual processor. And you wouldn't lose any performance either.

 

Mastershroom, have you undervolted your CPU? Did you also underclock your CPU too, says 800Mhz, I thought the T9xxx have a 1066Mhz FSB.

 

I've undervolted my T9500, but I don't underclock it; I let Intel's SpeedStep do its own thing. Not all T9xxx series have 1066 FSB. The T9300 and T9500 have 800MHz.

 

Undervolting is better than going through the pain of buying a P8600, disassembling/reassembling your notebook and selling the T9550. And there is always the risk of voiding your notebook's warranty if you screw up something.

 

From what I got of the first post, I'd say you are primarily concerned with heat and longevity of the laptop.
Easily done through undervolting.
If you do that, you should be able to reduce the power consumption needed for CPU when on maximum use and it will run cooler by about 10 to 15 degrees (maybe 20 degrees ... depends on how low you can undervolt).
End result would achieve what you desire and you don't have to switch the cpu's.

 

The P processor won't add that much more battery life to what you got. Probably about 10-15 minutes for the most.

 

Ok, i'm gonna start the undervolting process in a few minutes. i'll check back soon!

 

I agree.

Take advantage of the various profiles in RMclock. Set the "performance on demand" profile and the "power saving" profile. Set the "power saving" profile in such a way that it uses your lowest multiplier. Then set it to be your default/startup profile. This will make your laptop start and run at it lowest spreed all the time (i.e. less heat). When you need the extra speed just right click on RMclock icon and switch to "performance on demand"
