3D11 Physics - Ivy Bridge LCC


Recommended Posts

0. Introduction


Since Sandy Bridge-E, we now all know how the 3DMark11 Physics subtest does not only scale well with threads, but also scales very well with memory frequency. Ivy makes memory clocking very interesting again, so why no have a little memory tweaking entertainment using the Physics subtest?!


1. LCC rounds


Since 3D11 Physics is stressing all cores, it might not be so easy for everyone to run 5GHz low clock, I suggest we get three rankings:


I'll make a hidden hwbot hce competition page so it'll be easier to track score and rank.


//edit: hidden hce page link => http://hwbot.org/competition/ivy_physics_lcc


2. Screenshot requirements


  • 3DMark11 score
  • CPU-Z Memory
  • TweakIT / GIGABYTE GTL / ... (other subtiming detail tool)

I tried DDR3-2800C11 without finetuning the subs and it was actually slower than the DDR3-2600+ C10.


As long as you can get tight subs and high clocks, I think you should be hitting 13.5K. Not sure if anyone is able to do 14k at 4500, though.

nice score zen what made you jump 100 points?

my score is up too.


tWWSR from 5 to 4 gave me like 50.


And TWCL from 8 to 7 gave me quite a bit.

TWCL 6 lost me about 40 points.
