945GM5/ 945GCM5/ 945GZM5 series
a.k.a. MS-7267 V4.x
NOTE: I know from experience that the MSI mboard model series can be hard to determine. If 945GM5 or 945GCM5 or 945GZM5 is NOT printed on the surface of the mboard in obvious larger characters somewhere, often found between the slots, or printed on the heat sink on one of the main chipset chips, look for a stuck on label on the top side of the mboard that has that printed on it, e.g. it may be ontop of the parallel port, or which model series it is MAY be shown in the bios Setup of the mboard, or in System Information in Windows.
If that doesn't help.....
- the 945GM5 series has the Intel 945G chip
- the 945GCM5 series has the Intel 945GC chip
- the 945GZM5 series has the Intel 945GZ chip
...but there is probably a heat sink stuck onto the top of that chip.
Which one it is can probably be identified by using a program that can do that on the Intel web site, or a freeware program such as CPU-Z may be able to identify it.
DDRII 400/ 533/ 667 mhz SDRAM (4 gb max for 945GM5 series)
DDRII 400/ 533 mhz SDRAM (2 gb max for 945GCM5/ 945GZM5 series)
2 DDRII DIMMs (max; two ram slots)
In other words.....
- the 945GM5 series supports up to 2 gb DDR2 400/ 533/ 667 mhz modules per ram slot
- the 945GCM5/ 945GZM5 series supports up to 1 gb DDR2 400/ 533 mhz modules per ram slot.
If the modules you have installed do not have a capacity larger than those sizes for the mboard series you have, there's no guarantee they'll work properly with or be recognized properly by your mboard...
- if the modules you've installed are rated faster than the max mhz the mboard series is rated for, unless their part number is listed for the mboard model when you use a ram configurator or similar program to look up which modules are listed for (are compatible with) your specific mboard model (e.g. Crucial sometimes lists modules rated faster than the mboard is rated for).
- if the part number of the module(s) you have installed is (are) NOT listed anywhere on the web for the mboard model when you use a ram configurator or similar program to look up which modules are listed for (are compatible with) your specific mboard model
