Hi all...

Ok, I broke down and bought higher-performance memory since that seemed to be my issue before. I bought a 2GB (2x1GB) Kit of Kingston Hyper-X. Specs:

Kingston Hyper-X
2-3-2-6 timings

My FSB runs at 533MHz (which is 133MHz single-rate) and up until now I've always had to lock my memory into 2:1 ratio. This means my memory is running at 266MHz. This also allowed me to tighten my memory timings (since I have always run PC3200 RAM).

With this memory, however, it's already running at CL2, so is it possible to tighten those timings anymore since it will be running at 266MHz instead of the rated 400MHz? (My mobo has an option for CL1.5)

Also, since the memory will be running slower than its rated speed, would it be possible to set it to a 1T Command Rate instead of the default 2T? (I've never tried this before)

Or would my performance increase more by allowing it to run at the rated 400MHz and leaving the timings stock (even though it will no longer match the FSB)?

I'm just trying to get the best possible performance out of this memory while keeping my system stable (also hoping this helps me overclock my machine a little higher than my old memory---but for now, just want to get the best performance I can out of it at non-overclocked speeds).


My Heatware:

System 1: 3.4GHz AMD Phenom II X4, 8GB DDR3-1600 RAM, 1x500GB HDD & 1x1TB HDD, Palit GTS 250 1GB
System 2: 3.0GHz Core 2 Duo, 2GB DDR2-800 RAM, 120GB HDD, BFG 7800GTX 256MB
System 3: Dual-533MHz PowerMac G4 Digital Audio, 1.5GB RAM, 120GB HDD
