Hello purtech It sounds like you are pretty much maxed out. One thing you could do is add another HDD. If you are not using the 4th HDD slot for a hot spare then you can add a HDD and configure it as a single drive RAID 0. Format that drive and set your page file on that drive. That should offload a lot of read/writes from the primary array and increase performance slightly. Thanks
What I am asking for is how to squeeze blood out of a turnip... I have this 840, is does TOO  much. It is a DC, File Server, has Quickbooks running on it. Whenever I do the Performance Analysis is always tells me "The system is experiencing excessive paging." Always. I know the culprit. We are phasing Quickbooks out. But in the meantime, any of you Guru's out there that can tell me is there ANYWAY to to increase the performance of the disk subsystem? Without buying new drives. "Tweak" the disk subsystem some? (Yes I have maxed out the memory. 8 Gig.) [IMAGE] Thanks,
