Performance
All who are following our RAM reviews probably noticed that previous reviews were prepared on Win7 x64 system. Ripjaws 4 DDR4-2666 review was prepared on a Win8 Pro x64 so previous test results are slightly different and we had to rerun all benchmarks once again on a new setup.
AIDA64 Cache and Memory Benchmark
As usual I will start from AIDA64 so one of the most popular memory benchmarks around.
G.Skill memory is performing good in this test. Results are up to 2GB/s higher than on the Corsair memory and about 7GB/s higher than on Crucial which is working at SPD settings compatible with JEDEC standards that you can also see in other memory kits ( including G.Skill and Corsair ).
HyperPi 32M
HyperPi 32M loves fast memory so it’s good to compare memory kits on this test. As we see differences are not as high as we could expect. Probably CPU’s cache frequency is still too low to show real performance of DDR4. I’ve set 3500MHz cache clock for all tests not to bottleneck memory but it’s still not high enough. On the other hand 3500MHz is about maximum you can set on non-ASUS motherboards so I didn’t want to pass this clock.
Futuremark PCMark8
PCMark 8 is the latest Futuremark benchmark which is testing whole system. G.Skill performs best in these tests but differences are not big. We can still see some improvements caused by tighter timings in Ripjaws 4 comparing to competition.
Futuremark 3DMark – Fire Strike Extreme
In 3DMark we can see memory improvements mainly in physics tests. Since we can find physics calculations in any form ( Direct Compute, Physx or other ) in most new games then it will also improve general experience while playing new, more demanding titles.
Cinebench
Cinebench is showing rendering performance and here we focus on CPU tests as they are using memory performance.
Looking at the scores we can barely see the difference because of already high performance of the test platform. During long work we can probably see bigger difference but again it looks like CPU’s cache clock is holding us down to achieve better results.
General performance of G.Skill Ripjaws 4 DDR4-2666 C15 is really good. XMP profile is well programmed and there are no stability issues. G.Skill tested this memory on a various motherboards so I think that all who are planning to buy this memory for non-ASUS motherboard will be also satisfied.
