Title: Litecoin GPU rig - system RAM? Post by: phor2zero on May 23, 2013, 07:23:40 AM 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?
Title: Re: Litecoin GPU rig - system RAM? Post by: bearpig on May 23, 2013, 06:53:05 PM System RAM doesn't impact too much when building a litecoin mining rig - 2Gb should be plenty.

Title: Re: Litecoin GPU rig - system RAM? Post by: Tootoot222 on May 23, 2013, 07:26:14 PM it mainly only uses the GPU ram, not the system ram for mining, just any normal amount to run your OS should be fine
Title: Re: Litecoin GPU rig - system RAM? Post by: Basaj on May 23, 2013, 07:26:46 PM 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.
Title: Re: Litecoin GPU rig - system RAM? Post by: phor2zero on May 24, 2013, 12:06:27 PM 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.

Post by: chalupa_batman on May 24, 2013, 09:14:51 PM 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)
Title: Re: Litecoin GPU rig - system RAM? Post by: phor2zero on May 25, 2013, 03:18:16 AM 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. |
