Hello Ram Guy,

My question is any other possible suggestions for a higher overclock or RAM speed without effecting rock solid stability or lower bandwith?

Hello Ram Guy,


I encountered stability problems when lowering the CPU multipler/relaxing memory timings while increasing the FSB. Appearently, thier is a know issue with ASUS 939 Motherboards related to 1T 1:1 timing and FSB unable to be stable over 230. Have you encountered or seen this type of issue?


Side note for Corsair Twinx2048-4400PRO memory, I was successful after much tweaking/benchmarking memory using the following optimal timings:


1:1 2-3-2-8 TRC 10 TRFC 12


Bandwith 7199 MB/s

Memory Read 6009 MB/s

Memory Write 2513 MB/s

Memory Latency 48.9 ns


Have you seen higher memory performance with this configuration?
