Installation and Testing

The GeIL evo FORZA DDR4-3000 has been installed with the following hardware:


Intel Core i5-6600K Skylake
Gigabyte Z170X-UD5
Swiftech Apogee XL
Swiftech H20-320 Edge
240GB Kingston HyperX Predator M.2 PCIe x4 SSD
Sapphire R9 290X 4GB GDDR5
Swiftech Komodo R9 LE
SilverStone Strider Gold 750W
Cooler Master HAF Stacker 935
Windows 10 Pro


Allowing the GeIL evo FORZA to boot with Auto SPD settings, it defaults to DDR4-2133 15-15-15-36 at 1.2V which is the lowest JEDEC spec for DDR4 memory. Selecting the XMP Profile in the BIOS raises the speed to DDR4-3000 15-17-17-35 and bumps the voltage to 1.35V automatically.



Comparing benchmark results in SiSoft Sandra to what we obtained with the previous Kingston HyperX Fury DDR4-2666 we find that the GeIL bandwidth surprisingly comes out slightly worse. With all other hardware in the system being identical, and memory timings nearly equal, we would expect the DDR4-3000 to outperform the DDR4-2666 in this benchmark, yet it scores around 1GB/s less. Looking at the memory latency benchmark by comparison, we find that it reports slightly more than 1.5ns lower (better) latency. The cache and transaction tests end up scoring the same due to the otherwise identical systems when it comes to processor and chipset.


There is typically a little extra headroom in most memory modules when it comes to clock speed, and without touching the voltage we were able to increase the GeIL evo FORZA to DDR4-3200 speed without issue. The timings were automatically adjusted up slightly to compensate, to 16-18-18-38 in this case. The next memory step available in the BIOS was DDR4-3333, which ended up failing on MemTest86. The two Sandra memory tests were re-run at the faster DDR4-3200 clock speed, with expected results. The bandwidth increased a small amount, although still not matching that of the Kingston, while the latency got slightly worse, due to the increased timings.

Let's wrap up with some final thoughts and conclusion.
