I did a search but couldn't come across any topics that address my problem.
I built this pc back in July (07) with a Patriot 2GB kit (PDC22G6400LLK) and running Windows XP and all was well.
I recently decided to add another HDD and installed Vista on it to run dual boot. I also purchased a second Patriot 2GB kit (again PDC22G6400LLK) and installed it.
The problem is that while my BIOS and CPUID will both recognize 4GB total memory, either OS will only recognize 2GB. I've tried every configuration of the modules that I can imagine, I've tried setting the timings manually in BIOS, I've tried using only one module, two modules, three modules, and all four, and it still only reads 2GB (Windows XP lists as 2,096,412 KB and Windows Vista lists as 2047 MB). I know that neither OS is probably going to show me the full 4GB, but I believe that it should show more than 2.0 GB. Anyone have a clue as to what could be the problem here? Thanks.
