G.Skill Ripjaws 4 F4-3000C15Q-GRR 16GB Memory Kit Review

Memory by leeghoofd @ 2015-03-02

With the release of Intel's high end X99 platform aka Haswell-E last year DDR4 became available for the big masses. Besides the massive available bandwidth these DDR4 modules can also pack a far higher density per stick. All this goodness is available at your disposal while requiring a mere 1.2-1.35Volts. Only drawback, as with each new technology at launch is the high retail price, Things have settled a bit and prices are slowly plummeting. Today we have a look at one of G.Skill enthusiast kits: the Ripjaws 4 F4-3000C15Q quad channel kit. While they have even faster kits in their lineup, ranging up to a massive 3400MHz out of the box. Today's reviewed 3000C15 kit has been heralded by many enthusiasts worldwide. Time to take a closer look.

Overclocking

Time to raise the bar and start tweaking the timings. If the memory failed the windows memory test we upped the voltages to see if we can stabilize the memory... Below are the achieved results, pretty impressive stuff if I may say so from a retail kit :)

CAS 14: 3000C14-14-14-16 Command rate 1T at stock 1.35 volts

CAS 13: 3000C13-14-14-16 Command Rate 1T at 1.425 volts

CAS12: 3000C12-13-14-15 Command Rate 1T at 1.545 volts

CAS11: 3000C11-13-14-15 Command Rate 1T at 1.725 volts

Next we tried to raise the memory frequency and got a nice 3300MHz bench stable at 1.45Vdimm at the same timings as the stock XMP. Anything higher would fail, now it could be the Integrated Memory Controller of the CPU was reaching its limits and needs cold to remain stable, or our kit is just running at its highest peak.
