Lenovo T500 ram
Windows 8, head to Control Panel System. You can also hit Start and search for “system” to find the page quickly. Look for the “System type” entry to see whether your operating system and processor are 32-bit or 64-bit
If you have 32 bit but have already ordered RAM. Consider a fresh install of Win10 64 bit. No rush through. Maybe on a new HD and dual boot. |

Then all is good.
If you do someday go to Win10 ... at least 8 gigs of ram would be advised. |

Based on the reduction in speed from 12800 to 8500, it's a different generation of chip, and it might well be a 16-chip 4GB module. In this case, it's not a "bargain RAM" problem, but rather a density issue. And those are hard to detect without some "evidence" from previous failures to work. That gets your suspicions running, and provides the impetus to hunt down the docs (whereever they're hiding this week). Paul |
