I have been trying to upgrade my computer to 16GB of RAM. My motherboard takes DDR2 400, but the memory company has sent me memory with label 'DDR2 - There's no '400' mentioned. The computer won't accept it and just continually beeps once every couple of seconds without the screen coming on. When I remove the new memory they sent me, it starts again as normal.
I know my motherboard can take 16GB. Each module is 2GB and I am loading them in pairs.
What is in there at the moment that works is:
DDR2-400 is 200MHz
Memory Type: DDR2 SDRAM
I gave the company my motherboard details because the first order was wrong too (I wasn't sent DDR2)
Okay, I need to issue a correct to the above post. This forum, for some crazy reason, doesn't allow me to edit my own post, so I have to issue a new post instead.
The first image shows two different modules actually. The module of RAM on top is DDR2-400 which is the module in my working system. The module you see to the bottom of the first photograph was the module the company sent me the first time and which was sent back to them: http://i18.photobucket.com/albums/b119/appy12/DDR_memor...
Thank you for that info. Yes, you are correct. They must be installed in their proper pairs.
However, due to the fact all these modules are (or at least should be) identical (all 4GB pairs 2 x 2GB), I'm not sure I can do any more to match them. I have tried swapping them around, just in case - I have also tried installed one or two pairs (I bought three pairs), just in case it was one of the modules at fault.
Unfortunately, it doesn't matter what pair I put in there - None of them will start the computer system properly.
What I do get is just one beep sound every couple of seconds, which is continuous.
Also I did just try with their memory in the slots on their own (ie. without my old memory in there) to see if it was the EEC-nonEEC memory mix problem. Unfortunately their memory doesn't work on its own either.
