Overclocking
Expectations regarding overclocking potential are raising when we think about G.Skill. This brand is always proving that their memory is well selected and tested. In every each of G.Skill memory kits I found some headroom for additional improvements. Let’s take a look what we were able to achieve on the Ripjaws 4 memory.
All overclocking results were performed on the ASUS Rampage V Extreme motherboard and i7 5820K CPU.
Presented results may vary on a different memory kit so we are not guaranteeing that our results or settings will be exactly the same on your memory kit. Overclocking is never guaranteed and we hope you understand it.
DDR4-2666 12-13-13-15 1N 1.40V
I’ve started from declared clock so 1333MHz ( DDR4-2666 ) at which I was able to tighten timings pretty much at the cost of higher voltage.
At the standard voltage of 1.2V it wasn’t possible to tighten the main timings but I could play some with additional settings that also improve performance. 1.25V was letting me to set CL14-14-14 and command rate 1N what isn’t bad. However best results were available when I reached 1.4V. Result of DDR4-2666 12-13-13-15 1N you can see below.
DDR4-2750 12-14-14-15 1N 1.45V
Going one step higher I had to raise voltage to 1.45V to keep memory stable at CL12. As we see, performance isn’t much higher than the DDR4-2666 result. Both settings are optimal and are clearly limited by CPU’s cache speed.
All who wish to keep voltage lower can try DDR4-2750 14-14-14-15 1N at 1.30V. These settings were also working good and passed all our tests.
DDR4-3000 14-14-15-15 1N 1.40V
Going further, I was able to reach quite stable setting of DDR4-3000 14-14-15-15 1N at 1.40V. It’s a result available for much more expensive memory kits it’s hard not to be safisfied seeing so high clock at tighter timings.
Again all who wish to keep voltage lower than 1.4V can try settings of 15-15-15-15 1N or 16-16-16-15 1.35V. Both were running good on a memory used for our tests.
If DDR4-3000 is not enough then what about DDR4-3411 ? I wasn’t able to stabilize our review kit at this clock but it clearly says that Ripjaws 4 has really high overclocking potential and maybe one of our readers will be able to make it stable at this clock.
