Benchmarks - Overclocked
As with all of our reviews, we pit the default speed system against the overclocked one in a head-to-head byte match. The only difference with memory reviews is that whenever possible the base system, CPU, Chipset etc..) are left at stock speeds and is something you can see in the Sandra CPU Tests. At that point the only performance advantage is from increased memory performance.
The effective overclock for these tests was pushing the modules up to 3800Mhz with only a slight bump in voltage.
Memory overclocking is a pretty arduous task of trial and error. As with most system overclocking the balance we are trying to maintain is a relationship between temperature, voltage and frequency. Chip quality will sway the balance and is where we normally land in terms of overclocking stability.
To be honest I am surprised I could get the modules to overclock at all considering that any timing changes would kill the system and voltage adjustments were not that helpful. Overall frequency was the only adjustment and while I could get the system to book at 3900Mhz it wasn’t stable enough to do anything. 3800Mhz appeared to be the absolute max and could be done with only a 0.25v bump in vdimm.
