As the day fast approaches for the build to replace my dead i7/930 (Wednesday), a major consideration has to be re-addressed. Both of my current machines have 6GB ram each and I am considering removing 1 memory stick from the dead machine to add to the new machine (i7/4770K, ASRock Extreme4, GTX660SC) giving it a total of 8GB of dual memory. The purlonged stick is part of 2 x tri-channel 6GB sets that was purchased at the same time and the batch numbers are close so I don't anticipate having any problems with it sitting in the new machine along with the other set. I really would hate to put off the build for another month to purchased sticks for the new replacement machine if this is not a practical solution to get it up and running as soon as possible. The question I need to impose -- Is anyone running Lunatics on an i7/950 (GTX460SE) with 4GB or an i7/4770 (GTX660SC) with 4GB successfully? I don't buy computers, I build them!! |

Any configuration of memory will work. Things are just optimum when you have all channels populated and in use. Which is 3 for the i7-950 and 2 for the i7-4770. Being down a channel just means you will be limited in memory bandwidth, but will most certainly work.

Thanks @HAL9000, limited bandwidth was already taken into consideration, my major concern was the amount of free ram with everything running. Right now the i7/950 with 4GB only has 1 GB free. This build has always been a practical exercise in limited finances I don't buy computers, I build them!! |

My HTPC running 8 CPU + a GPU seemed to cope just fine with 4GB while running BOINC & my other background video things on it. Depending on how you will be running your tasks I expect BOINC & the apps will probably use 400-600MB. If that machine is running AV it can eat up nearly all of the RAM when it does a scan. So that is the only thing I would be concerned about. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Concerning the AV, why didn't I think of that. I'll have to keep an eye on BOINC when the AV does its daily scan at 03:00. If there is any conflict I can always snooze BOINC until the scan is done as it only take a couple of minutes to do. I don't buy computers, I build them!! |

I was thinking the AV might just suck up a large amount of memory and hold onto it. Causing the memory for the BOINC apps to start swapping. The AV IS uses at work holds on to about 2GB all of the time it seems. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

My entire internet security suite, which is a spin off from Computer Associates, (firewall, AV, malware, lan security) only holds onto approx. 300MB of ram while the system is up. The quick virus scan takes approx. another 192MB, but the scan only runs for 1~2 minutes. Its nice to have a 128GB SSD for a system drive. I remember that it took up to 20 minutes on a 250GB HDD.

Just do a full scan while you keep a watch on it Cliff and you'll find out the max that it will use. Cheers. |

The standalone full scan on 2 x 128GB SSDs took 5~10 minutes (C: system, D: data). Didn't put a stop watch on it. I should note that the full scan excludes the BOINC directory and the 250GB E: drive which is the backup drive. It did peak around 384MB with it hanging around 234~244MB for the most part. The scheduled daily scans only do the system drive. I don't buy computers, I build them!! |
