CPU upgrade in laptop

post #1 of 6
Thread Starter 
I have HP envy 15-3040nr that has a i7 2670QM, and I want to put in an Extreme Edition CPU in it, this one.

http://ark.intel.com/products/53478/Intel-Core-i7-2960XM-Processor-Extreme-Edition-8M-Cache-up-to-3_70-GHz



Both being Sandy Bridge, I assume that it will work, but I wanted to ask.


Also, the heat is an issue with the CPU that is in my computer as of now, it gets to 90c on a full load. I was told that if I disabled hyperthreading, the heat wouldn't be so bad.
I am replacing the thermal paste tonight, an I will see if the temps are better with HT and without HT.




Here are some screens (These are on battery, I am sure thats why its not turbo boosting.)

That is just sad that them put VT-d on the M CPUs, but not the K's...


However, it should work provided that the motherboard can accept it. It's the same socket though I wouldn't be surprised to see the motherboard having issues and needing a BIOS/UEFI update. I would ask HP or look around on their forums first.

The heat shouldn't be much different between the two CPUs...since most of the time it will be in a non-turbo mode, but even at full load I would not expect the "Extreme" CPU to be more than maybe 5° warmer. The vcore and such will be about the same, but the extra clock will warm it up some more.

I've never noticed much of a temp difference by disabling HT though...just going off of the tech I can't see why this would lower the temp. I suppose it one less thing for the CPU to be doing, but I doubt it would effect the heat output much. I've never really tested that though.

I found that during testing, the CPU frequency dumps to 798 mhz and just pins itself there for a while, and then goes to 2.5 ghz, , but it NEVER reaches turbo boost.

Sounds like you should check out ThrottleStop. It was designed to help with these sort of laptop problems. Most modern laptops need to be plugged into AC power for maximum performance. Do not use ThrottleStop to try and force your CPU when on battery power. It is possible to damage or shorten the life of your battery if you do.

I tried it out, thanks! It worked great!

I still didn't get to 3.1 ghz though, but its pinned where I want it. Its not getting much hotter than it did before while gaming, less dropped frames.

Rep'd!

3.1 GHz is the maximum turbo boost speed. This is only available when a single core of your CPU is active. As more cores become active, the maximum multiplier will decrease. You can have a look in the ThrottleStop - Turbo Ratio Limits (TRL) window to see what the specs are for your CPU.

Turbo Boost can also be limited by power consumption. Intel designed this feature so you get maximum turbo speed, usually for up to 28 seconds on a mobile CPU, and then the CPU might have to slow down a little so it can operate under the maximum TDP power value. This should be shown in the ThrottleStop TPL window. Some CPUs have these values unlocked so you can bump them up for a little more performance but many laptops lock this feature in the bios.

Glad to hear that ThrottleStop was able to fix your 798 MHz blues. I am not sure what laptop manufacturers were thinking when they dreamed up these throttling schemes that leave you running at less than one third of your CPU's rated performance.
