Ive been wanting to get 2.5-2-2-5 ddr510 out of my ram for ages and have finally done so. My trouble is i am getting less bandwidth, and inturn a slower system than when i had 2.5-3-3-10. I have discovered the reason for this is that i had to turn my tREF seting in bios to 0128 for me to be stable. Doing so has decreased my bandwidth. I was wondering if anyone had any ideas as to how i could benifit from my tighter timings (2.5-2-2-5), rather than loosing out. Its been a long time no post but i remember getting good advice last time i used this forum, Thanks guys.
