Anyone done this before? I have a locked i5 sandy bridge i want to undervolt and underclock can this be done?

ideally running at 1.9GHz at the lowest possible voltage
>>
Just a quick update.

Went from 50W to 30W running at 1.9GHz @ 0.888V is it safe to try and drop it to 0.6V?
>>
its probably possible to disable cores too if you dont need them
>>
i'm getting some weird rounding error problem on prime95.

Ill try disabling the 2 cores.
>>
seems stable with 2cores gonna try dropping the voltage a little more
>>
Why are you doing this? What do you use this computer for?
>>
>>60281604
Plan on running it 24/7 as a server. Using the Intel GPU but not the CPU.
>>
Using 46.5W at full load
28W idle on 0.872V cant seem to get it any lower than that.

I guess that will do
>>
>>60281723
tried manual voltage, no eist or turbo, c1e only enabled?
>>
>>60281161
>>60281610
Sell it and buy a raspberry, unless you need x86, then there's good amd soc apus.
>>
>>60281161
Interesting, getting a 3550 for 24/7 soon, does anyone know how much the power draw decreases?
>>60281476
This would be retarded, I would rather sell it and get a two-core CPU.
>>60281610
Maybe think of a T Pentium or Celeron if you don't need much performance.
>>
>>60282643
>would rather sell it and get a two-core CPU.
Why, with turbo boost and cores disabled there should be no difference.
>>
>>60282724
Because i5s are worth more. You can probably sell this one and get a low TDP Celeron and 30 € from it.
>>
>>60282748
Seems like an hassle, plus you can always uncripple it if you find out you need more power.
>>
>>60282868
What are you planning to run on it? Running two or even one core would be the best solution to save power.
>>
Why can't i just limit the clocks to say 133mhz and turn it into a pentium 1?
