Your experiences with swapping a lower TDP CPU to a higher TDP?

I'm thinking about buying a CPU for my laptop that is a higher TDP than what is supported. A higher 35W vs. my supported 25W.

Does anyone have any experiences with swapping to an unsupported higher TDP wattage? Searching the net hasn't come up with much except for saying that if there is too much of a gap the computer wont 'post'.

Thanks

 

I put a 45 watt quad core in a laptop that's meant for 35 watt dual cores:

Well my laptop is a lot older than that Dell. Nice are you going to sell that beast?

I guess if the same rule applies then there shouldn't be a problem. You didn't have any issues with the BIOS?

 

It is usually quite dependent on the cooling scheme of the laptop and the voltage regulation circuitry. Sometimes you will get away with it and other times you wont. You should research your particular notebook and see if anyone else has tried.

Just because a proccessor has a 35W TDP, doesn't mean it will use that much power. a lot of the time if it hasnt been tried before the only option is to try it out. Bear in mind that the extra current that a 35W CPU draws might reduce the life of the notebook's voltage regulation chips.

 

Well apparently the Turion chips can undervolt themselves or at least downclock and idle themselves better than the Sempron chips.

Also I'd be able to finish things faster which means less time at max voltage, which means less heat. I think I'll have a look at my heat sink, and use some of the best thermal paste and give it a go in the name of science. I can always go back to my Sempron if it doesn't work.

On top of that I do have a very good cooler.

If anyone else has had experiences with swapping voltages on TDP I'd like to hear it though.

 

Actually, I put the old processor back in and returned it.

 

like i said in theo ther thread use good paste and rice grain sized dab of it. the only other thing i might suggest is better bigger cold intake hols if the bottom covers restricts the cpu fan. as it is all about heat more than power also the VRMs can vulnerable but, that seems like a desktop thing.

First TDP=/= power consumption. No point to explain it, but it's a fact.

As long as it's a compatible upgrade(2 cpus being in the same family, have the same socket), you shouldn't worry about TDPs, I upgraded from a 25W p8400 to a 44W x9100 in my asus G50VT, that's quite a jump of TDP and I even keep the x9100 overclocked 24/7 for one and half years now, haven't had a single problem with it.

 

Its best to stick with a cpu that is an upgrade option for your laptop.

Some machines are built better than others and have the power and cooling needed to handle a higher demand cpu, however... others do not and it can cause damage or failure.

Worst case scenario if it is not an upgrade option for the laptop it may not support the cpu at all being locked out at the bios level.

 

I replaced a single core AMD TF-20 (15W) with a dual core Turion X2 TL-58 (31W) on an Emachines E627 almost 2 years ago. The computer runs warmer than with the TF-20, but there have been no problems with it. When you first boot up with the new CPU, you may have to remove the CPU from Windows Device Manager and reboot to force Windows to detect the new CPU.

 

Ok thanks a lot for all your replies I have purchased the CPU and I will let everyone know how it goes when I install it. Hopefully everything will be positive, I can at least be sure that it will be much better than the CPU I am currently using.
