Lenovo A55 Model 8975-75G

Request for Lenovo/IBM Thinkcentre A55 Model 8975-75G, CPU Intel E2140, Bios version: 2oj948a

Having a couple of issues, I did try and make my own Slic using Andy's tool, but pubkey didn't match.
Also for some reason even the original BIOS will only allow the CPU to run at a max speed of 800mhz instead of 1.6ghz, the same thing happens in Linux or Windows, the only information given is 600-800mhz if I run commands in Linux, tried older BIOS's and it's still the same, if I turn off GV1/GV3 in BIOS it will run at 1.6ghz but I lose Speedstep and uses too much electricity. I have had the CPU under load but it still will only go between 600-800mhz.

Code:

"analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.0 us.
  hardware limits: 600 MHz - 800 MHz
  available frequency steps: 800 MHz, 600 MHz
  available cpufreq governors: conservative, userspace, powersave, ondemand, performance
  current policy: frequency should be within 600 MHz and 800 MHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).
  boost state support:
    Supported: no
    Active: no"

Attached files, RW everything report original and after slic flash, screenshots of slic toolkit before and after flash.
