32GB of RAM isn't expensive. If anyone's interested, here's what I'm getting and why:
ASRock 970 E3
Thermaltake TPX-1275 Plat.
G.Skill Ares 32GB RAM
Sempron 145
x2 - Sapphire Vapor-X 7970 6GB
Total $1700
Just 2 GPU's initially, to calculate hash rate and profit potential. I can add a second power supply and 3 more cards if it's worth it. At the least, simply replacing the CPU would make this a decent gaming machine I could sell or use for a racing simulator.
I'll update this thread in a few weeks when it's up and running with both Bitcoin and Litecoin results.
Topic: Litecoin GPU rig - system RAM? (Read 742 times)
i think having a litecoin rig would be a good idea. once all the asic's are released, the difficulty on btc will go crazy. switch it over to ltc at that point (pretty much already there)
Thanx for the input. One source recommended having as much system ram as total VRAM on the graphics cards. i.e. - with five 6GB 7970's (35 GB ram) I'd want a full 32 GB on the system. Specifically for Litecoin of course. I know Bitcoin isn't ram choked.
I have a 60 GH/s miner coming, and plan to expand with several Terrahash or KnCMiner rigs later this year. Still debating if its worth building a $3000 Litecoin rig.

I was curious about this too, Most rigs seem to have about 8gb but a very small hard drive, just enough room for an OS and the official bitcoin/lightcoin wallets.
it mainly only uses the GPU ram, not the system ram for mining, just any normal amount to run your OS should be fine
It has to be around the normal amount
System RAM doesn't impact too much when building a litecoin mining rig - 2Gb should be plenty.
Building a GPU rig for Litecoin mining. Does scrypt use the GPU card RAM only, or should I max out on system RAM as well?
