This will tell you quite a bit of information about what type of RAM you have installed, but it may be more productive to look up the Motherboard model numbers it returns, and find compatible RAM that way. dmidecode(8) is better than nothing, but it doesn't return SPD data for me: Handle 0x002B, DMI type 17, 27 bytes Memory Device Array Handle: 0x0029 Error Information Handle: Not Provided Total Width: 64 bits Data Width: 72 bits Size: 2048 MB Form Factor: DIMM Set: None Locator: DIMM0 Bank Locator: BANK0 Type: DDR2 Type Detail: Synchronous Speed: 400 MHz Manufacturer: Manufacturer0 Serial Number: SerNum0 Asset Tag: AssetTagNum0 Part Number: PartNum0 (Maybe those DIMMS aren't SPD capable? I don't know). According to http://en.wikipedia.org/wiki/Serial_presence_detect dmidecode(8) reads only BIOS data, but not the eeprom from the DRAM modules themselves. The same page also points to spdmem(4). OpenBSD's spdmem(4) driver could be interesting to port to FreeBSD: http://www.openbsd.org/cgi-bin/man.cgi?query=spdmemsektion=4 as it allegedly reads the eeprom data directly off the DIMM modules. Even so, for best results it helps if you install a uniform set of RAM modules, and I don't think there's any option other than popping the case and pulling a RAM stick for a visual inspection if you want a 100% certain match. I've already seen mislabled DIMMS in the past, and usually, the information stored in SPD was more reliable than the one on the stickers (but not always).

How to get the SPD infomation in freebsd ?
In windows, the `CPU-Z` utility can be used to get the SPD(Serial Presence Detect) information. How about freebsd ? I want to get those information especially frequency to add more memory. And i donot want to touch the hardware.
