I havent checked that because my dock died the other day and I don't have use for 1080p anymore.
The last thing I ran at 1080p was static 30fps and it was great. Sometimes it would drop to 20-25. It's worth a try, what do you have to lose? Don't expect smothness though.
If you don't use 4ifir...
The ram modules on the erista are binned at 2400mhz. That's what I recall from the last time I looked it up.
Also 1886mhz on the ram doesn't require raising the voltage. It's just past 2ghz that needs more voltage and it's still within the safe zone (what manufacturer says).
I think...
For anyone wondering about erista's capabilities. I'm using 4ifir stage 7+ and it's rock solid.
cpu 2295 for loading ( I use their optimized preset)
gpu 998
ram 2131
It does 1080p 30fps 95% of the time. It drops to 20-25 of there are a lot of effects happenening at once on the screen.
Probably. My erista can do:
CPU 2091
GPU 921
RAM 2150
No crashes with this config. It did crash when I attempted to push 2200Mhz on the ram a few times.
