I work in the IT Department at my company, and we are in the process of upgrading all of our older desktops to 4GB of RAM (sounds simple, right?). The problem is when the memory hits 4GB the OS becomes suddenly unstable (i.e. programs crashing, graphics issues (particularly with IE9), and overall slow, sluggish performance). These computers are Lenovo Think Centre's and the models are A57 9851-A7U's. The Motherboard IS compatible with 4GB according to various sources.
*Extra Info:
- The RAM we are putting in is DDR2 PC2-5300 (667MHz 2x2GB Unbuffered)
- You can stop IE9 from crashing by choosing, in internet options under the advanced tab, to use "software rendering instead of GPU rendering*".
- When we downgrade the RAM amount back to 3GB, the issues stop.
Here's what we've done so far with troubleshooting...
The first thought was that the problem was the two GPU's in the PC (all of these computers have the integrated Intel GPU AND a separate Nvidia GeForce 6200 card). So we've gone the route of disabling the integrated intel gpu, but the problem persists. Next, we figured the BIOS probably needs an update, so we flashed to the most current verison of the BIOS from Lenovo's website (still the problem persists).
