Overclocking DDR2 800 C4 memory?

[Ken429]

I have 2G of Corsair Twin DDR2 800 C4 memory installed in three different computers and have not had a problem. I am trying to overclock an E6750 processor on an abit IP35 Pro MB. I seem to run into a wall (calculation error) at a FSB setting above 430. I have the memory set to 2.1V and 4-4-4-12 timings. Should I reduce the timings to 5-5-5-15 and try to raise the FSB beyound 430? If so, have I really gained anything - increased FSB speed versus slower memory response? Should I consider faster memory? It looks like memory beyond DDR2 800 C4 the memory timing go to 5-5-5-15? The system has a Zalman 9700 cpu cooler and never gets above 58C under full load.

Intel loves bandwidth far more than timings. When it comes to pure bandwidth speed, I would increase it and raise timings. Set to 5-4-4-12 and raise FSB. Then 5-5-4-12, etc. etc.

 

That DRAM should be good for ~1000Mhz with 5-5-5-15. Not guaranteed but I would certainly think you can give it a try.
