First off, great clocking hiwa, those are some excellent sticks!

i think no one have a cpu can handle 2500 memory 24/7 same for 2400 and 2300 i'll test cl7 and 6 later just to see where they can go for dailyuse users

Not necessarily. I run my 870 at 4GHz / 200 BCLK 24/7 with only 1.4vVTT. Using the 12x multiplier it runs the sticks at their rated 2400 / 9-11-9-28, stable as can be. The CPU is on water, but still not sub-zero. It's not just software stable either. I beat the snot out of them with an Ultra-X hardware RAM tester (check out the review here). For softare stable, I can drop VTT down to a comfortable 1.375v.

Anyway, just saying 2400 is possible 24/7 without issue & without damaging voltages. 2500...that's a lot tougher.
