Motherboard: Gigabyte GA-X58A-UD3R, ver 1.0
BIOS version: F5
Memory: G.SKill F3-12800CL9T-6GBNQ
Processor: i7-980X
OS: Windows 7 Ultimate, 64-bit
I have 6GB of memory installed, but Windows 7 64-bit is reporting the following: "6.00GB (2.00GB usable)." When I power cycled the system, I noticed that only 2GB of memory is posting. CPU-Z corrrectly reports that I have slots 1, 3, & 5 filled with 2GB DIMMS each, and a total of 6144MBytes of memory running on triple channels. I've tried swapping the DIMMS around and updating (then downgrading back) to beta F6i, but the amount of memory that POSTS (and which Windows 7 64bit reports) is 4GB.
As for settings in BIOS, this is what I'm using (pretty much pulled from http://gskill.us/forum/showthread.ph...highlight=UD3R, with the exception CPU clock ratio setting):
CPU Clock Ratio - 25x
QPI Link Speed - AUTO
Base Clock Control - Enabled
BCLK Frequency - 133
Performance Enhance - Standard
Extreme Memory Profile - Disabled
System Memory Multiplier - 12
DRAM Timing Selectable - Quick
CAS Latency Time - 9
tRCD - 9
tRP - 9
tRAS - 24
Command Rate - 2
DRAM Voltage - 1.500V
All of the other memory settings are set to AUTO
I have not manipulated any of the voltage settings pertaining to the CPU, uncore, etc. Any suggestions?
