How to emulate T4000 in T5000
T4000 has less RAM memory thant the T5000 and the levels of performance are lower. To emulate the same level of performance of the T4000 is possible by using the following steps.
1. Limit RAM memory: In the /boot/extlinux/extlinux.conf add the mem variable equall to 64G in the APPEND specification. The following command does the exact change.
sudo sed -i 's/APPEND/APPEND mem=64G/' /boot/extlinux/extlinux.conf
Reboot the board for applying the changes.
2. Power MODES: Following the next modes represent the MAXN MODE and the 70W for the T4000. It will reboot the board after the change.
sudo nvpmodel -m 2 # to emulate MAXN mode of T4000 sudo nvpmodel -m 3 # to emulate 70W mode of T4000
How to stop emulating
To undo the changes you can set again the board the power mode you desire. More information in the Tuning Power section.
Then remove the mem=64G from the /boot/extlinux/extlinux.conf.
sudo sed -i 's/APPEND mem=64G/APPEND' /boot/extlinux/extlinux.conf
