Memory replacement on my laptop is driving me crazy.
I've got a Toshiba A215-7422
. According to Toshiba it's got this memory installed "1024MB PC5300 DDR2 SDRAM." So, I ordered these memory modules, 2GB PC2-5300
And that's where the trouble begins. I inserted the two new dimms, and the computer refused to boot. No problem, I thought, it must be bad memory sticks. So, I exchanged them for new ones. Still nothing. ( I did try testing both sticks individually and in different slots, with each set.)
Now, I can see four reasons for this.
1) I've got the wrong memory
2) The software doesn't like the amount of memory.
3) I somehow got a hold of four bad memory sticks.
4) I don't know how to install RAM.
I've tried to look up whether PC2-5300 is not the same as PC5300, but the limited info that I can find indicates that it's the same exact memory with just slightly different names. Also Crucial had this to say "Each memory slot can hold DDR2 PC2-6400,DDR2 PC2-5300 with a maximum of 2GB per slot."
I can see no reason for the bios or OS to be unhappy with the new RAM. It's only 4GB total. (I'm running Vista Home Premium).
The odds against getting four bad sticks must be astronomical.
Finally, I keep removing and re-installing the original sticks with no problems (I'm on the laptop now). So, if it's me, I'm somehow managing to install the new memory badly while installing the old memory correctly.
So, what the hell? Can anyone suggest what the problem might be? I'm not computer illiterate, but I'm no expert by any stretch. (Frankly it could be something super obvious.)
