My NAS

Were you able to open up the 2nd core on your sempron 145? I have mine open and it was stable. Makes quite a difference, especially using virtualbox plugin.

Were you able to open up the 2nd core on your sempron 145? I have mine open and it was stable. Makes quite a difference, especially using virtualbox plugin.

How do you determine that both cores are being utilized ? I have the HP N40L which has the AMD Turion™ II Model Neo N40L, i was under the impression its architecture was based around the Sempron?

Thank you

Here is a list of unlockable amd cpu's:

Just because it's on the list does not mean the additional core will function properly. You also need a southbridge sb-710 or higher to do this. Anyone attempting to open up an additional core should unplug all hard disks and run memtest for like 3 passes, with 0 errors, before they consider it stable. Hard drives should be disconnected when adding additional memory or changing memory timings too. Then test your system with Memtest before connecting the hard drives. You download an iso and burn it to cd. Then boot machine from cd.

On most Asus motherboards for these cpus the bios will detect if it is possible to open an additional core. You will have an option on the bios splash screen to hit 4 to activate the core. On other motherboards consult your manual. I did an ECS build for my mom's friend like 3 weeks ago and it was kind of tricky to find it in the bios. Usually it is just 1 setting in the bios that needs to be turned on.

The Turion II is a dual core processor. This feature is not available on this cpu. To check how many processors you are using you can use this command in cli:

cat /proc/cpuinfo | grep processor

0 is the 1st processor
1 is the 2nd processor
etc...

PS- Note difference in benchmark scores on AMD Sempron 145 before and after core unlocked. I'm sure there is a big boost in performance when using one virtual machine with 1 core assigned to it as well.

Ever measured the power consumption of your build?

I would guess that machine would take about 47 watts idle. Maybe a bit more then mine because he has a bigger psu.

@tekkbebe

couldnt find any info on your OMV build. I guess you have the sempron unlocked; but did you try to undervolt?
I'm thinking of building a NAS was looking into similar configs to compare power consumption. 45-50 W seems a lot for a idle system.

My system is an unlocked sempron 145. It idles at 47 volts. I have not undervolted and don't want to. I'm happy with energy vs. performance where it is at now. This does not mean you cannot undervolt.
