Hi all,
I just added a matching pair of 2GB DIMMs to my system for a total of 8GB (4x2GB).
I ran into an issue where only half the RAM was being detected at POST. After a few hours of troubleshooting, I believe the problem is related to memory timings in BIOS.
Before adding the RAM, the timings were set to what the memory is rated at, which is 7-8-7-24. But after the upgrade, when I try to change these values from 'Auto' (which is 9-9-9-24), only 4GB is detected. The system runs fine with the timings on Auto.
Questions:
1. Is there a relationship between the number of DIMM slots used and memory timings?
2. Realistically, how much of a performance hit would I be getting with the higher timings?
3. Is there a BIOS setting that I'm missing that would allow me to run at the rated values?
System Specs:
P55A-UD4P (LGA 1156, Gigabyte)
i7 860 (minor OC @ 3.36GHz)
8GB DDR3 1600 1.6V G.Skill Ripjaws, 7-8-7-24 (4x2GB)
Thanks in advance!
