Sempron 145 unlocking questions

post #1 of 4
Thread Starter 
Hello, well, I was going to get the following setup:

Sempron 145
ASUS M4A78LT
Kingston DDR3 @ 1333 2x2GB

So, doing some research I read that many Sempron 140 unlock a second core, and I also read that some 145 do the same.

I was wondering if the TDP of the processor will be the same after do the unlock (If it's successful, of course), since I'll have another core running and generating heat that must be dissipated. But would it be necessary to get an aftermarket cooler or does the stock heatsink can handle it?

Also, should I crank up the voltage a little bit to maximize stability?

Thanks thumb.gif

TDP should remain the same, and the stock heatsink will handle it just fine, and you should still be able to get a mild overclock as well! and yes, it's best to slightly adjust the voltage a little higher to achieve stability after unlocking the second core, but it's not always needed.

TDP will increase a little bit, but even with the 2 cores, they still barely produce any heat.
You can touch the small stock heatsink and you'll see lol.

you can safely overclock an unlocked sempron up to 3.5ghz without the need of changing the stock cooler.
