Having problems with your Lenovo ThinkPad R51e Notebook ?

Maxed memory or drivers causing R51e causing BSOD ???

\015 I recently upped the RAM in my r51e to 2048kb of Crucial RAM. My R51e has been acting fine up until now. After getting the ram installed, I began seeing the BSOD. Sometimes before login, sometimes after login. Usually don't get the BSOD when booting in safe mode.I ran Microsoft's memory diagnostics and my RAM failed the LRAND and Stride6 tests -- with the cache on. With the cache off, it passed the test. I've updated all of my drivers but I'm still suspicious that it could be an issue w/ the built-in ATI video chip.Can I turn my processor's cache off? Is that the issue? I swapped out both sticks of RAM and they run fine by themselves. But, when I run them together and max out my RAM, I get the BSOD.Also, when I have 1gb and 512kb of RAM only 1gb is available when I boot up.thanks!Dave\015

Answers :

You're mixing 2 different things. the cache is very small, 512KB , 1MB, 2MB 4MB(at the newest CPUs) and it comes with your CPU, when you change the CPU, you change the cache, you cannot work without the cache, its impossible.
\015\012the ram, however, is upgradable. and its typical sizes are 512MB, 1GB... etc.
\015\012have you updated the BIOS?
\015\012are the memory sticks fit for your computer (some times, the fact the memory sticks have different speeds can cause problems?
\015\012
\015\012you are not suppose to see the cache (512kb) of your boot up
