This info would state the DDR version (DDR, DDR2, DDR3) and the module's speed rating. Also, Kingston would also list the motherboards that this module was / is known to work with.

It is safe for you to plug it in and test it. If the motherboard lacks that divider, no damage will be done. It just won't start, and will beep an error code. The BIOS won't enable the slot, unless it is happy with what it sees. Mechanical keying, prevents truly (voltage) incompatible modules from being mated. If it fits, nothing will burn. The description above is not a complete one. Memory can be registered or unbuffered. Unbuffered memory is typically used on desktop systems. Registered is used in servers. The above description doesn't mention those terms, so I cannot be sure about that aspect of the module. In the picture here, is a registered DDR2 DIMM. The long rectangle in the middle of the DIMM, is the address bus register and PLL (phase locked loop) function for the clock signals. Unbuffered DIMMs for desktops, lack that rectangle. The DIMM here, also has nine memory chips, forming a 72 bit wide memory array. That means the memory is protected by ECC (64 bits of data and 8 bits checksum). http://images17.newegg.com/is/image/newegg/20-134-963-S01?$S640W$ So those kinds of details are missing from the description, and as long as the module has no heat spreader metal cover on it, you should be able to visually examine the module and figure out any other details needed. In any case, it'll be safe to plug in and test. The mechanical keying scheme is what helps in that respect. If the key and notch don't line up, it is the wrong kind of RAM (or you need to rotate the module 180 degrees in your hand and try again). Memory companies like Kingston and Crucial, feel they are under no obligation, to release details about the memory used in proprietary computers. So when you go to the site and look up memory specific for your ThinkCenter A51, they tell you to "use this" and give you a module part number. Since you're buying memory for that specific computer, they don't give you any details. On "generic" modules, intended for thousands of different computers, they give plenty of details. In this case, the KTM3219 is intended for specific purposes. The fact the ramshopping.fr gave any description at all, is a miracle. You might also look on the paper label on the module itself, for further hints about the classification of the module. For example, it might say at least, that it is "DDR2-400". If you are forced to, you can tell a bit about the module, based on the chip configuration soldered to it. Paul |
