OKEY DOKEY!!! i think i finally found the problem and its NOT the 32-bit 64-bit RAM deal either!!
when running (RAM in SINGLE channel) WIn7 32-bit i get 4GB installed (2.99GB useable)
when running (RAM in Dual channel) Win7 32-bit i get 4GB installed (1.99GB useable) PROBLEM!!!!!!!!
for a while i didnt understand, but today i installed WIn7 64-bit in dual-boot and i got the following
when running (RAM in SINGLE channel) Win7 64-bit i get 4GB installed .............as it should be
when running (RAM in DUAL channel) Win7 64-bit i get 4GB installed (1.99GB available) PROBLEM!!!!!!!!
so i think my 1 RAM slot is not working, only single channel is working. Motherboard is a Biostar Tpower I55.
the board has 4 slot, 2 in white and 2 in orange, primary boot slot are the orange, however the when i use the one orange slot i get the problems above, yet when i have the RAM installed in single channel (1 in white 1 in different orange slot) i get the result as above.
what do you think? is the 1 orange RAM slot faulty?
