jsammy Posted December 2, 2010 Share Posted December 2, 2010 I've been running this setup for over a month, and since Day 1, I have not had the system correctly recognize all 6GB (1 kit, 3x2GB dimms) for more than one day at a time. I have experienced: system boots, all 6GB recognized, Windows gives me 0xc0000428 cannot verify digital signature error, I press ENTER to continue, system reboots, now only 4GB (sometimes only 2GB) recognized, Windows starts, Windows recognizes 4/2GBsystem boots, all 6GB recognized, Windows loads, everything seems ok, Windows blue screens (mostly PAGE_FAULT_IN_NONPAGED_AREA, sometimes NTFS_FILE_SYSTEM), I reboot, now only 4GB (or 2GB) recognizedsystem boots, all 6GB recognized, no problems, next day, turn on pc, only 4GB recognizedsystem boots, all 6GB recognized, windows memory diagnostic tool starts, no errors found, Windows loads, Windows recognizes 4/2GB Sometimes I notice that the system will not recognize all of my RAM, but I'll shutdown and power up 5-10 minutes later, and all 6GB will be recognized (then repeat above). Even though recognized RAM is less than 6GB, CPU-Z still sees all 3 dimms. I have tried all a) AUTO settings, b) XMP Profile, c) the following base settings: Ai Overclock Tuner: ManualCPU Ratio Setting: AutoIntel® SpeedStep Tech: DisabledBCLK Freq: 133PCIE Freq: 100DRAM Freq: DDR3-1066MHzUCLK Freq: 2133 MHzQPI Link Data Rate: AutoDRAM Timings: 8-8-8-20-4-59-8-6-20-0 (Auto), 1N-56-56-56 (Auto), 4-4-14-11-11-11-7-6-4-7-7-4 (Auto)CPU Voltage Control: ManualCPU Voltage: AutoCPU PLL Voltage: 1.80QPI/DRAM Core Voltage: 1.25000IOH Voltage: 1.10IOH PCIE Voltage: 1.50ICH Voltage: 1.10ICH PCIE Voltage: 1.50DRAM Bus Voltage: 1.64DRAM DATA REF Voltage on CHA: AutoDRAM CTRL REF Voltage on CHA: AutoDRAM DATA REF Voltage on CHB: AutoDRAM CTRL REF Voltage on CHB: AutoDRAM DATA REF Voltage on CHC: AutoDRAM CTRL REF Voltage on CHC: AutoLoad-Line Calibration: AutoCPU Differential Amplitude: AutoCPU Clock Skew: AutoIOH Clock Skew: AutoPCIE Spread Spectrum: Auto I have used both Intel's stock HSF and the Corsair A70. Temperatures seem OK. CPU idles in low 30s. I have checked for bent CPU pins and making sure the HSF backplate is not shorting the mobo. I can't say for sure (how does one measure "too tight"?), but A70 seems about as tight against CPU as stock HSF did), and its orientation seems balanced enough (I reseated 3 times with comparable results). For testing purposes, I labeled the dimms 1, 2 and 3. My memtest86+ results: each module individually in slot A1, no errorseach module individually in slot C1, 1 and 2 no errors, 3 has errorsall 3 modules in A1, B1, C1 -> with previous configurations, error; with above configuration, no errors after 2 passes, Windows runs fine, turn on next day, only 4GB recognized Since my last tests, I have changed my timings to 9-9-9-24-4-88-8-6-30-0. I will report back. I would like to get the system stable at 1066MHz. Once satisfied, I would like to try 1333, and eventually 1600. I have not over-clocked the CPU (running at stock 3059MHz).
