So, maybe it's possible to have a desktop motherboard of the year 2007 with 16gb ram, non server motherboards or workstation motherboards I mean. A lot of users, here, like to do that, maxing out the hardware to limits unthinkable back then.
I have an old 2005 PowerMac G5 with 16GB of DDR2. Just eight sticks of regular non-ECC DDR2. The mostly 32-bit Leopard OS has no idea what to do with it all, but PPC64 Linux can kinda sorta make use of it. Really though, it's a bit like stuffing 128MB in a 486. The CPUs are just too slow to run programs which need that much memory.
On topic though, I used an AM2 system as a file server ages ago. 5000+ CPU, 4GB of DDR2, integrated graphics - just basic stuff. AM2 never really impressed me. I always thought of it as the cheap, boring platform that AMD had to throw together because DRAM manufacturers were winding down DDR1 production--even though K8 had, at least initially, seemed better optimized for regular old DDR. If I remember correctly, my carefully tuned Opteron 185 on S939 consistently measured around 3% faster on pure CPU tests, probably thanks to its use of CL2 DDR400 memory.
The memory latency was really quite dreadful on my AM2 system. I had always wondered if the GeForce 6150 iGPU had anything to do with it, or perhaps the way it was plumbed in to the memory bus. I remember it being really slow for Windows Aero. Like, even worse than Intel GMA 3000 somehow.
As others have already said, AM2+ and Phenom II is where things start to get fun.
