Using FB-Dimm's in a Home Machine

Hey,

I'm throwing together a fast but cheap micro atx desktop w/ integrated video that I plan on using mostly for music production until I decide to save up for a good graphics card so I can also play games on it too.


For the build, I'm planning to use this Gigabyte motherboard:

But, the problem I'm having is that I'm planning to start out with 4 gigs of memory (2 x 2GB sticks) but eventually I'll want to bump it up to 8 gigs. And, as is the case with a lot of micro atx motherboards, there is only two memory slots.

Now, although it would be easy to achieve 8 gigs of memory by getting 2 x 4GB sticks, it's not quite as easy to pay for those 4GB sticks, as they run over $150 for a single 4GB stick. ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820134863 )

But, I did try looking around online and I came across 4GB memory modules that were cheaper, around $80 per 4GB stick, but they're marketed as server memory because they are FB-DIMMs. ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820134913 )

I did try reading up about fully buffered memory and tried to find out whether they're only practical in a high data-bandwidth server environment or if they would work fine in a home machine too. But, the only thing I uncovered that might be bad about running FB-DIMMs in a home machine is that there's a little extra latency seen in every day computer use, but that it's not much.

I was able to find the proper speed of FB-DIMMs for my motherboard (DDR2 800) and the memory has a cas latency of 5 (which is good & low, but pretty expected for memory in this speed range).

But, before I make any decisions on what to buy, I would like to know if anyone has any insight on the disadvantages / advantages of using FB-DIMMs in a home machine...

Will running FB-DIMMs in a home machine being used for music production cause an annoyance due to a lot of extra latency?

Would there be any advantage to having fully buffered, ECC RAM in a home machine besides the extra data bandwidth (I'm not specifically planning to be doing RAID w/ multiple hard drives).

Anyone have any first hand experience doing this or any insight on why it would be a good or bad idea?
