Hello, i am new to unlocking and overclocking, i only have a basic system to experiment with, i am working with a AMD Sempron 145. Whenever i try to unlock the other core, the computer shuts down and restarts and says in the post that the unleash mode failed. Does anyone know where i am going wrong?
Any AMD CPU with unlocked cores is far from certain you can unlock. Some are locked because they need to make more of a lower range. Alot are locked though as the other cores are bad so rather than throw away they lock it and sell as a lower model with less cores.
Its luck of the draw unlocking any CPU. Dont buy one thinking you can unlock successfully. Buy the CPU that YOU NEED and if it unlocks further thats a bonus
It's doing that because the fourth core is unstable. There is a reason why it is a three core CPU and not a quad core. Back when AMD started making the Phenom II they had a problem with some of the quad core CPU's and they were unstable. Instead of trashing them they deactivated one of the cores and sold them as three core CPU's. Yes you can unlock the fourth core the catch is that it might not be stable. In that case you have no choice but to set it back to three cores or get an actual quad core CPU.
Oops I dont know why but I thougt he said Athelon II 3 core. Still though the end point is still the same though it's unstable and his only option is to go back to a single core because it will not run as a dual core.
Ok, Thanks eveyone.
Will start looking for AMD Phenom.
One last question, is the AMD Llano any good to use or would i be wasting my time?
Llano is an alright budget processor, it's essentially a 32nm Athlon II with integrated graphics. I wouldn't bother looking at one though, since you have an AM3+ motherboard and Llano uses FM1, they aren't compatible.
I also find trying to unlock pointless even if learning for a future build, AMD currently doesn't manufacture anything that can be unlocked the way Athlon II/Phenom II did. FX 4100 and FX 6100 both use the same die as FX 8150 but have modules(cores) disabled, and there have been no reports of unlocking these yet, it seems AMD found a way to prevent core unlocking. If your not aware, Athlon II/Phenom II are no longer in production, so those won't be around for long to bother trying an unlock on.
