Hello, I have windows 7 64bit. Asus P6T Deluxe V2 Crusial Ballistix DDR3 (3x2 2gb) 1600 MHz ( PC3-12800 )
In BIOS :4088 MB ram In Win :4,00 GB ram In CPU-z:6144 MB ram On the ram kit it is fitted some kind of heat-sink with LEDs witch I assume indicate that they are "working/thinking". DIMM_A1 & A2 seems to doinf their thing, C1 is "frozen" (the LEDs).. Any suggestions??
More aboutshow 6144mb windows show
best bet would be chek the socket for bent pins reseat the CPU could help
Run memtest86+. If you get any errors, run it using only one stick at a time. I bet you will find a defective stick. If, by chance they all test out well, test a known good stick in each slot to test for a bad slot.
