Problems adding RAM to M58p

[rwbaker]

I have a M58p 3484-Y2S with 2x 2gb sticks of RAM running Win7 x64.  I purchased 2x 2gb sticks of RAM to add. When I add the RAM, I get the Memory Error beep (1-3-3-1).  I've tried booting with just one of the new sticks, or both new sticks with the same results. I doubt I was shipped two bad sticks of RAM. It seems as if it's the wrong RAM, but it seems to be right.

Computer: M58p 3484-Y2S

New RAM: Crucial 2GB 240 Pin DIMM DDR3PC3-10600 UnBuffered; model # CT25664BA1339

Lenovo's recommended RAM: http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?...

RAM I purchased: http://www.crucial.com/store/partspecs.aspx?imodule=CT25664BA1339

Any idea what's going on here?

Turns out the problem was the subset of RAM. Curcial specified the 'generic' part we needed. However, specifically, the motherboard only supports the 16-chip style of ram -- 8 chip on each side of the board.
