Hi newcomer and welcome to the Tom's hardware forum.
start, write msconfig, this brings up the configuration utility, click the Boot tab, and then click the Advanced Options button, in that window, there is a setting for Maximum Memory. Make sure the checkbox for it is clear (not checked), then reboot your computer.
OK,I did that,no change, but now I think that I have a bad 2GB stick. I moved all 6 pieces around and with the bad stick, it would always count up to 4GB or the wrong amount. I can get it up to 10GB but the last "bad" one drops it to 4 or 8GB. How would I know if I'm getting the full benefits of triple channel?. On bootup(Award F5) it just counts the amount but doesn't say triple channel as my last ASUS P4800-E deluxe did. It said 2GB DDR-400 in DBL channel mode.
My GIGABYTE X58-UD3R Rev.1 doesn't tell -just the amount.
System info does say 12 total; 8 useable
How do I vote you the best answer/reply
