Everyone,
I just put together a system consisting of a 620W Seasonic M12II PSU, an Asus M5A97 R2.0 MOBO, an AMD FX6300 CPU, an EVGA GTX-760SC GPU, and 8GB of Corsair Vengance CMZ8GX3M2A1600C9B DRAM in two memory sticks. I am not doing any overclocking (yet). The first thing I noticed was that the BIOS detected the DRAM as DDR3-1333 rather than the DDR3-1600 that it actually is, so I manually selected DDR3-1600. I also noticed that it detected CAS/RAS settings of 11-11-11-28 instead of the 9-9-9-24 that it supposed to run at. Just to see if the CAS/RAS settings made any difference I ran the AIDA64 cache & memory benchmark on both settings. As I expected, the memory speeds showed a slight increase for the 9-9-9-24 setting, specifically, the read speed went from 22032 to 22309 MB/s and the latency went from 71.8ns to 66.8ns. (Since I'm using the trial version of AIDA64 the write and copy speeds were not shown.) However, was surprised me was that the speed of the L1, L2, and L3 caches all decreased, with the worst case being the L3 copy speed. It went from 39961MB/s to 31167MB/s. Since this computer is primarily for my grandson's gaming I tried both settings with Planetside 2 but there was no noticeable difference (~55FPS in both cases).
So in the end I don't know why the DRAM was not recognized correctly in the first place or which settings are actually better. Is it better in increase the DRAM speed at the expense of the L1, L2, and L3 cache speeds or viceversa, or are there also some cache settings I should be tweaking too? I would appreciate any information or suggestions on this issue since my experience in fooling with all these settings is extremely limited.
Thanks,
Ray
