一、只超频CPU到1.6GHz，不超频AI算力的方法：
1. 首先将Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20240428.run上传到OPi AI Pro开发板的Linux系统中2. 然后添加执行权限：
chmod +x Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20240428.run
3. 然后运行 ./Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20240428.run --full 命令更新固件
./Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20240428.run --full
4. 然后输入小写的 y 确认开始更新
5. 更新完成后的打印输出如下所示：(base) root@orangepiaipro:~# ./Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20240428.run --fullVerifying archive integrity... 100% SHA256 checksums are OK.

7.执行以下命令查看cpu频率和NPU算力
grep "aicore freq" /var/log/npu/slog/device-0/device-0*
[INFO] LPM(-1,null):1970-01-01-00:00:15.393000 [avs] [AvsProfileLimitUpdate 55] profile[1] aicore freq[750] cpu freq[1600] config done
如果使用下面的命令能看到aicore freq变为了750（原先是500），说明切换到了12T的AI算力 ; cpu freq[1600] 表示已经升级到1.6G
二、超频CPU到1.6GHz，同时超频AI算力到12T的方法：
1. 首先将Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run上传到OPi AI Pro开发板的Linux系统中2. 然后添加执行权限：
chmod +x Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run
3. 然后运行 ./Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run --full 命令更新固件
./Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run --full
4. 然后输入小写的 y 确认开始更新
5. 更新完成后的打印输出如下所示：(base) root@orangepiaipro:~# ./Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run --fullVerifying archive integrity... 100% SHA256 checksums are OK.

(base) root@orangepiaipro:~# npu-smi set -t nve-level -i 0 -c 0 -d 1
Status : OK
Message : The nve-level of the chip is set successfully.8. 然后重启系统，如果使用下面的命令能看到aicore freq变为了750，说明切换到了12T的AI算力(base) root@orangepiaipro:~# [INFO] LPM(-1,null):1970-01-01-00:00:14.817000 [avs] [AvsProfileLimitUpdate 55] profile[1] aicore freq[750] cpu freq[1600] config done[INFO] LPM(-1,null):1970-01-01-00:00:14.456000 [avs] [AvsProfileLimitUpdate 55] profile[1] aicore freq[750] cpu freq[1600] config done
三、如果您拿到的开发板使用的三星16GB内存，但是在Linux系统中使用free -h命令只能看到8GB，请更新下Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20241022.run这个固件，方法如下所示：
1. 首先将Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20241022.run上传到OPi AI Pro开发板的Linux系统中2. 然后添加执行权限：
chmod +x Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20241022.run
3. 然后运行 ./Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20241022.run --full 命令更新固件
./Ascend310B-firmware-7.3.t3.0.b309-rc-signed-8t-1.6ghz-20241022.run --full
4. 然后输入小写的 y 确认开始更新
5. 更新完后断电重启即可6. 然后在Linux系统中使用free -h命令看到的内存大小应该就正常了
