Maybe, but there is no guarantee that it will work anytime you use different memory modules. Plus, you cannot run in dual channel that way and dual channel configurations are desirable (Good) because it doubles the bandwidth. You always want to try and use memory modules that are the same size and have the same or very close specifications for speed, latency, voltage, and timings, so that it will run in dual channel. 2 x2gb, 2x 4gb, 2x 8gb etc. will all usually run in dual channel. 2gb+8gb, 4gb+8gb, etc. will not ever run in dual channel.
G41 Chipset motherboards use low-density memory. Most all memory manufacturers have stopped making that kind of memory years ago. You can still find it on eBay.

No, max you can have on that board is 8 Gb, 2*4 gb , i would be skeptical of it accepting only 1 8 gb stick too....Even if your board accepts those 2 sticks, the max you're going to get is 8Gb., so basicaly those 2 Gb would be useless...You might be able to use them for backup or using them on other system...
