Hey guys, I have gone through the well known pc-hell since I bought and installed an additional 2 gb of memory. It was 2*1gb apacer ddr2 pc6400 memory sticks.
Suddenly my system started to crash unexpectedly, even when I wasn't doing anything. For a week I was totally panicking every moment when working on some project that it may crash every second. Finally I found out about memtest and it told me that one of the sticks was faulty. So I brought them back today and exchanged them with 2 new ones, because I didn't trust apacer anymore, I exchanged them with the only other brand they had, I never heard of it before, it's called Nanya Elixir and it is again 2*1 gb at ddr2 pc6400.
When I put these new memory modules in, my pc didn't start up anymore, maybe I didn't push them in firmly enough or something, something kept beeping and nothing happened. I was afraid that my mobo might have got confused or something so I reseted my mobo (I think).
After that it didn't work for a while either, but than after removing and adding the memory modules for the 12th time or something, suddenly my pc started up. But somehow, even if I put in the old 2*512mb sticks too, so I have 3 gb memory, my system keeps telling me that I have 1 gb of memory. When I remove the old 2*512 mb sticks, it still is 1 gb, when it should be 2 gb. It also tells me that I have single channel memory. What is wrong and do I have to change something in my mobo bios to make it see that I have more than 1 gb of memory and make it dual channel?
I am gonna lose my head, in the meantime I wish I had never tampered with the system, with 2*512 mb memory I was doing fine or at least trusted my system, now I expect it to collapse any second.
