I have been running 6gb of platinum OCZ memory (discontinued) tuned to 7-7-7-18 at 1.6v. I have the 920 overclocked to 3.8ghz at 1.2125v (290 bclk--ends up downclocking the memory slightly to 1523mhz). It has been running flawlessly going on 2 years, but it seems like I've been getting close to maxing out the RAM at times.
I was looking for advice on an upgrade to 12gb (3x4gb in triple channel). It seems like there are not a lot of options out there in this configuration with CAS 7. How important are these timings? Will I see any problems by going with a CAS 9 kit or with my current OC setup? Is this a reasonable upgrade to consider at this point in time?
Thanks for any information.
edit: should have mentioned I have an ASUS P6T deluxe v2.
