What a waste of time, spend on the money on anything else, other then water cooling ram, heh.
Even if you do overclock the ram, you arent decreasing the latency, at best you can push the mhz up a tiny bit,or a large bit but then if its large you have to increase the cas latency, blowing away most of the increase anyway. So, utter waste of time.
I mean i guess if you already spent 1000 on a cpu, 1000 on a gpu, and 1000 on a monitor, not to mention a few thousand on other peripherals, and water cooling for the cpu, gpu, etc, etc. If you have already dumped 10,000 into the system, i mean sure why not overclock/watercool the ram.... It wont have any significant impact on the system performance, but if you've already splurged on a buncha other stuff, why not!
