I am having a problem with my RAM timings. I am using an ASUS P6T6-WS revolution board. My CAS# is going from 8 to 4 after my machine wakes up from sleep. I am using Patriot Viper 6GB (3 x 2GB) 2DDR3 SDRAM DDR3 1600 (PC3 12800).
My i7 940 is overclocked as such:
CPU ration: Auto
Speed Step: Enabled
pcie freq: 100
Dram Freq: DDR3-1604
My ram Settings are:
Memory Frequency 800.0 MHz (2:10)
CAS# latency (CL) 8.0 (4.0 after wakeup)
RAS# to CAS# delay (tRCD) 8
RAS# Precharge (tRP) 8
Cycle Time (tRAS) 24
Row Refresh Cycle Time (tRFC) 88
Command Rate (CR) 2T
Uncore Frequency 3200.1 MHz
And in the BIOS I have added the RAM timings according to the "1st Information" listed "8-8-8-24-6-88-14-8-30-0"
I have no idea whether or not CPU-ID is reading this incorrectly, but I want to know if there is something wrong in these settings that confuses the mobo and has it trying ti overclock from 8 to 4.
Any advice would be really appreciated. Thanks ;-)
Yeah...they are an 8-8-8-24 @ 1600. I used Everest to check this out last night as well and saw the same 4 cas after waking from sleep as in CPUID. I had a problem when I was not using an XMP profile...cas would go from 6 to 4, but I didn't really know it was a problem at that point. I think this might be an underlying instability in the ram, or someplace else (no idea where else it would be), because my prime95 tests are nuking around 4-5 hours in.
I just don't understand how, with a manual setting of 8, it ever goes to 4.
