Overclocking
Overclocking is never guaranteed so the presented results may vary from results on other memory kits. I am not recommending overclocking if you do not know what are you doing. High voltages may damage hardware and it will not be covered by warranty.
All overclocking results were achieved on ASUS Maximus VIII Hero motherboard with the latest BIOS. It’s important to use new BIOS version as it improves memory overclocking potential.
I was focusing mainly on stable settings and safe voltages for long work so no more than 1.4V. For competitive benchmarking you may need higher voltages but it’s hard to say how high voltage is actually safe limit. Most users won’t try to set really high voltages anyway.
In the table below you can see settings which passed longer stability tests. Considering results in benchmarks on the previous page of this review, best is to try to set the highest memory frequency. HyperX Savage is based on Hynix memory IC what was mentioned at the beginning of the review. This IC doesn’t like higher voltages at DDR4-3200 or higher frequency. At the same time can work at tight timings at higher clock what makes it good option for overclockers and all who wish to achieve best memory access time.
DDR4-3200 CL14-15-15 1.37V was the highest stable setting possible on the tested HyperX Savage memory kit. To set lower timings was required voltage above 1.45V but it wasn’t fully stable.
I think that overall results are good, especially when we compare them to XMP profile which is DDR4-3000 15-16-16 1.35V. Without raising voltage was possible to set 1600MHz ( DDR4-3200 ) CL15 what is above average result even for higher frequency and much more expensive memory kits.
Below we can see result at DDR4-3200 CL14-15-15 1.37V, Command Rate 1N and quite tight sub timings. The same settings have passed additional tests like really long PCMark 8 or AIDA64 memory stability test.
DDR4-3333 or higher settings were not possible or would require to lower timings too much what of course would cause performance to drop.
I think that overclocking potential will satisfy most users, even these more demanding. Even without overclocking performance is good but if you seek better results then you can always play with settings and maybe you will be more lucky.
