Well, those are all ddr3. I thought it wont be a problem..
I checked crucial advisor and it said i can even buy ddr3-1600
Strange
I know this is the old thread and sorry for reviving it, but it can be helpful for someone with similar problems. I have this motherboard and I'm actively using it almost every day. It was used in Acer Veriton M480G bare-bone PCs and is made by MSI for Acer.
Motherboard name is Acer MG43M and came in two revisions: 1.0 (which I own) and 1.1. Except for going from electrolytic caps to polymer in some places, I'm not sure what other HW changes are made. There are 2 branches of BIOS for this MB: P01 and P02. AFAICT P01 is used on revision 1.0 and P02 is used on revision 1.1. BIOS files could be downloaded from
The Retro Web.
This being said - this motherboard is very picky when it comes to RAM modules. It has 4xDDR3-1066 MT/s slots which can work in dual-channel mode. It supports up to 8GB system RAM total. If you want to max out RAM you need to use 4x2GB modules - but it will not work with single sided sticks (trust me - I tried)! You need to use
dual sided sticks! And not only that - high capacity chips, even on dual sided modules (rare, but they do exist), will
not work.
I'm using these modules: 4x Apacer 78.A1GC6.BS1, but these will also work - Transcend JM1333KLU-2G (personally tried) or Kingston KVR1333D3N9/2G (personally tried). All 3 modules mentioned are populated in this configuration: 128Mb x8 in 2Rx8 (dual rank x8). This translates to having 16 chips per module or 8 per side or 128MB per chip.
Since BIOS of this motherboard does not let you have any control over memory timings it is strange this motherboard boots with 1066-8-8-8-20 clocks, none of which are part of JEDEC standards AFAIK (SPD4.1.2.11).
Note: In my personal experience with DDR2 and DDR3 module regarding clocks: You can safely put RAM module of certain clock speed in system which supports 1 level down speed - for example 1333MHz modules will probably work in 1066MHz systems, but it may not work in 800MHz configuration. 1600MHz will probably work in 1333MHz systems but it may not work in 1066MHz systems.
