I am posting this under RAM however I am pretty convinced the RAM modules are fine. System specs shown on left. I have a GA-965P-S3. (https://www.gigabyte.com.tw/Products/...ProductID=2457
4 Slots for RAM, dual chanel.
I have upgraded the RAM buy purchasing 2 x 2GB XMS2 DDR2. (https://www.corsair.com/products/xms2dhx/default.aspx
This is to be installed with the existing 2 x 1GB TWINX DDR installed (https://www.tigerdirect.com/applicati...874&CatId=2264
Both of the new 2GB sticks work fine.
With all RAM installed (6GB) is shows up in bios and Windows 7 64bit as 5GB.
With 1 x 1GB stick (old stuff) removed and the other 1 installed in either of the remaining slots, it shows 4GB instead the installed 5GB.
Essentially, it works fine with 4GB (the two new sticks).
shows 5GB with 6GB installed and shows 4GB with 5GB installed.- tried every stick in all slots in all configs.
I have reset the CMOS, latest bios, and windows.
I have read this has something to do with memory remapping,
however there is nothing in my bios (even in Advanced) showing this.
