I own an hp pavilion xt919 that runs memory at 100mhz (PC-100). However the memory that came with it is PC-133. It's details are:
128mb, SYNCH, 133MHz, CL3
I tried instaling some PC-133 RAM just for consistency but none were backwards compatible and thus didnt work. So I bought the following PNY memory:
256MB SDRAM 32x64(I beleive): 256s100 DIMM, PC100/66 UPC code: 751492196152.
The computer registers the memory so that I have a total of 384MB showing in my system information and also my BIOS, HOWEVER when I tried to sign onto AOL I got a Blue screen error stating that I have to restart my computer if it is the first time I received this message and mentioned that something was unstable and the error message was to prevent damage.
A few hours later while I was on AOL a message box popped up saying to close one or more programs to free up 1mb of space. Then a fatal AOL error occured and closed AOL. Why is this memory causing this problem? Should I return it and try another brand or is there a setting in the "cache" I can adjust?
