G.Skill DDR3-1600 CL7 6GB PI Series DDR3 Memory Kit Review

Overclocking Results

In order to determine what frequencies were stable with this kit I set vCore to 1.25v, vtt to 1.35v, and vdimm to 1.50v, 1.65v, and 1.75v. 

G.Skill DDR3-1600C7 PI Series Overlclocking Scaling

No, there isn’t an error in the graph. These sticks simply didn’t scale past DDR3-1850. There were a few instances where DDR3-1900 would pass a few loops, especially towards the looser timings like 9-11-9-27 but never would it complete a run. However, even with this odd scaling these results aren’t too outside of the realm of possibility given how the kit seemed to wall at DDR3-1850, just like the DDR3-1600C7 ECO series we reviewed previously. 

G.Skill 1600C7 Pi Series at 1.4v

Above you can see a SuperPi 32M run completed at DDR3-1600C7 with only 1.4vdimm. Unfortunately the Gigabyte X58A-UD9 only lets me select 1.3vdimm or 1.4vdimm and 1.3vdimm wasn’t stable. So, even though the sticks don’t scale well with increasing voltages they at least don’t drop in frequency with a drop in voltage. Looks like we definitely have a set of ECO sticks in disguise.

G.Skill DDR3-1600C7 PI Series at 1920MHz CAS9

Here is the best frequency I was able to manage: DDR3-1920 but with very loose timings of 9-11-11-27-2T. There was no chance at cracking DDR3-2000 though; I ran out of tricks from my rather extensive bag.
