GSKill Ripjaws 4 DDR4 3000Mhz CL15 Quad Channel Memory Review

As with all of our reviews we pit the default speed system against the overclocked one in a head to head byte match. The results of this are shown below. The effective overclock here is 3.5Ghz with a BCLK of 125Mhz with a resulting memory clock of 3333Mhz.  The timings were set to CL16 which allowed the modules to run at 3400Mhz! but required a BCLK tweak that wasn’t fully supported by the MSI X99A Godlike.  The goal of this overclock was to increase memory bandwidth and lower overall latency.  Even without changing CPU speed there was over 60GB/s of memory bandwidth available with no change to memory voltage.

62GB/s !!

The interesting thing about these modules is that they were relatively easy to overclock but didn’t respond well to BLCK adjustments.  For instance I tried running these modules at 3400Mhz and while every benchmark was stable the scores were lower than expected.  Voltage didn’t help so there is a chance that there is an incompatibility on the motherboard.  To attain 3400Mhz a combination of memory frequency multiplier and BCLK was needed and sadly anything over 125Mhz caused the system to slow down.  This has been a typical issue with MSI Gaming motherboards and ultimately not all that important.  3400Mhz+ is possible with these modules you just need the right motherboards to make it happen.
