For sure... I think the cache on mine is really weak, so it affects the IO and ram stability.

Makes me sad about what I achieved with the 3600 cl15 kit. Was hoping for 4000 plus but without crazy 24/7 voltages I'm sure I can only achieve it for temporary for benches. Curious what kind of voltage you are running to get it down to cl12 tho.

Hello

Maybe as high as 1.85V or 1.90V on the memory for SuperPi stability. Not something even close to considering if your goal is 24/7 settings.

Haha oh I know it's not 24/7 but I was just curious. Even at 1.5V I can't get 1t to even boot at 3800+. If I used xmp settings manually entered it takes 1.48V just to use 3600 cl15 1t. In the end losing 1t and running 3800+ proved more benifitial

I think I need 1.9ish for 4000 12-11-11 1T with those timings like in the pic, but for 4100+ 12-11-11 1T it's closer to 2.1v. I'm sure if I got em real cold during winter and used 2.15-2.2, I could do 4200 12-11-11 maybe. Not sure though. I'd probably have to loosen rtl to 51/52 or 52/53

Really nice sticks for sure, although this thread is aimed at slightly more pragmatic settings wink.gif Would be interested to see what sticks like that can do on a daily basis when coupled with lower voltages. Currently the only entry above 4000 is my own, and that was on a pretty run of the mill 3866 kit that was rushed out the door by TG at launch.

Beyond those speeds really is down to the memory controller, board and what voltage is needed when looking at stability.

Yeah man I really want to spend time and figure out what is stable, but I work really odd times and sleep during the day so I tend not to have much time for testing things like stability frown.gif

What else is your machine doing when you're asleep during the day? tongue.gif
