128GB+ Ram setup

[ntg]

Does anyone have any experience with 2-way motherboards with a RAM setup in excess of 128 GBs? I'm interested in knowing a bit more about any possible gotchas regarding large RAM chips.

Although some current high-end motherboards have 8 RAM slots and support up to 128GB of ram, unless they're using server type ram (buffered, ECC), you won't find any 16GB Non-ECC ram stick on the market... They're not yet available.
If you use a server board then yes, you can have more than 128GB (the highest density server ram currently is 32GB/stick so technically you can have a computer with 256GB of ram if you have the $ to spend). However, serverboards most likely won't support 2-way SLI because they are made for servers and not for gaming.

Having said all that, I'll be interested so know how you manage to get this all set up...

I'm talking about a server board. Nothing really maters except memory capacity, disk and network I/O. Still exploring but I may have to shoot for 256 GB of RAM or more, hence the need for large memory chips, probably 16 or 32 GBs. I'm looking to create a Redis server that will host some pretty large data collections.

My investigation so far shows that for such a configuration, 75% of the cost is RAM. I don't have any personal experience with chips larger than 4 GB, hence my post here.
