Demonstrating DDR

1. 先用memory找出相關資訊 · 2. 那東西太多了, 篩選一下, 假如我只要看大小跟插幾隻記憶體(擷取Size) · 3. 也可以查看記憶體頻率, 改成擷取個Speed即可 · 4.

I am trying to read PS DDR memory complete 4GB, I am able to read the PS DDR Low memory 0x00000000 to 0x7FEFFFFF (~2GB) using Linux command dd.

To really test the DDR speed, you'd want to use a dedicated DMA channel, removing the CPU from the transfer.

I want to buy a RAM module for my laptop. I used the sudo lshw -short -C memory command and I've got this information. I know everything about ...

Use the lshw command with the memory class: $ sudo lshw -C memory # Some things about firmware and caches *-memory description: System Memory physical id: 13 ...

The DDR frequency can be determined runtime from Linux/QNX making use of the k3conf application from Linux userspace.

The only info I have been able to get is using the command “dmidecode -t17”, but this still doesn't tell any info specifically about the die- ...

Here's the exact way to find out whether you have DDR2 or DDR3 Memory on Debian or Ubuntu systems: sudo dmidecode | grep DDR

DDR frequency is measured in transfers per second, not cycles. The memory shown in the answer is DDR3-1600 (which uses an 800MHz clock).

Open the terminal application or log in using ssh command. · Type the “ sudo dmidecode --type 17 ” command. · Look out for “Type:” line in the ...
