Maxed memory or drivers causing R51e causing BSOD ???
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.
Re: maxed memory or drivers causing R51e causing BSOD ???
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.
the ram, however, is upgradable. and its typical sizes are 512MB, 1GB... etc.
have you updated the BIOS?
are the memory sticks fit for your computer (some times, the fact the memory sticks have different speeds can cause problems?
you are not suppose to see the cache (512kb) of your boot up
A 6ya expert can help you resolve that issue over the phone in a minute or two.

if you are using windows xp, then follow these steps: 1) right click "my computer" icon, select "advanced" tab, click settings button towards the right of "start up and recovery" and click "edit" tab a notepad window appears with some text in it which reads something like this :
[boot loader] timeout=0 default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /FASTDETECT
modify that text to look like this: [boot loader] timeout=0 default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /FASTDETECT /3GB /userva=2800 /NoExecute=Op
Warning : only the "/3GB /userva=2800 /NoExecute=Op" has to be added extra else you will mess up
2) save the notepad and insert max ram, and check, if any BSOD's if the problem persists, then it is hardware related.. Most probably one of your ram stick may be the problem child(which may be either incompatible with your motherboard or defective)
Ram should always be paired. Same type, speed and size in each slot. You may have 1 SIMM/DIMM/DDR that has 2 sides of chips and the other with 1 which will do exactly what you state.
RAM reads across the chips simultaneously. So if you have a different one in each slot it can go bonkers and do goofy stuff on you.
On the bottom of the laptop there are one or two panels, remove the screw securing the panel. The RAM module are behind one of the panels. If the memory module does not fit in the memory slot, then you have the wrong type and you need to purchase the correct memory type.
Your friendly computer shop can advise you on the correct type and speed of the memory module your laptop requires.
