RGB lighting

The RGB lighting of the DELTA DDR5 modules is very bright and powerful, so my camera can’t capture it at all representative of the human eye. Also, the points of light that you might see in the video or the pictures are not visible to the naked eye. The color gradient is very even overall and there is almost no difference in brightness vertically. Only at the punched-out “R” does an LED shine through almost unobstructed, which provides another additional highlight (in the truest sense).

Personally, I like the white modules even a little better, although the color gradient in the white acrylic over the white aluminum heat sink somehow reminds me of northern lights over a mountain landscape. Overall, the modules should integrate very well into most systems, whether with RGB lighting on or off. Of course, in addition to the videos, there are also a few still images, for those who prefer that.

SPD information

As always with RAM modules, a look at the built-in “identity card”, the SPD, is not to be missed. Here, the Asus “Worktool” software with the “DDR5 SPD” function is used again to read out and visualize the information. We don’t find anything unexpected in the Topology tab. These are single-ranked modules with 8 ICs of 16 Gbit capacity with an x8 interface.

The timings according to JEDEC are also effectively standard for DDR5, with a clock frequency of at least 1996 Mbps and nominal 4800 Mbps, at timings tCL 40, tRCD 40, tRP 40, tRAS 77, tRC 117, tWR 72, tRFC1 708, tRFC2 384 and tRFC_SB 312. In addition, the other values for tCL from 22 to 40 are supported, in each case only with even numbers due to the 1:2 transmission (gearing) between the memory controller and RAM that is standard for DDR5.

The manufacturer information about the components is really interesting. The manufacturer of the SPD chip with the hex ID “80B3” already looks familiar from past tests. The company in question is Renesas. Although this manufacturer also has PMICs (Power Management Integrated Circuits) in its portfolio, Teamgroup again opted for a different manufacturer for this component. “8A8C” in this case stands for Richtek.

The manufacturer of the modules is of course Teamgroup, for which the “4EF” stands here.  We meet an old acquaintance at the manufacturer of the DRAM, i.e. the actual working memory ICs. Because “80AD” stands for SK Hynix. Even if the stepping or IC type cannot be read out correctly here, we can determine this relatively reliably in the early days of DDR5. Currently, Hynix only offers the 16 Gbit M-Die memory modules, which currently have the best clock potential in DDR5.

Finally, let’s move on to the XMP profile and the important related information. Of course, the PMIC type is important especially for overclocking RAM with more voltage, which is read out here as “XMP (OC) PMIC” and can thus provide more than the 1.435 V VDD and VDDQ provided by JEDEC. The recommended configuration for this kit is “1DPC” as always before with DDR5, i.e. 1 DIMM per channel.

The full XMP profile at the clock rate of 6400 Mbps and thus a clock rate of 3200 MHz uses the timings tCL 40, tRCD 40, tRP 40, tRAS 84, tRC 124, tWR 96, tRFC1 944, tRFC2 512, tRFC_SB 416. The command rate is set to 2N for the first time in a DDR5 kit in our tests. For voltages, Teamgroup specifies 1800 mV for VPP, as well as 1350 mV each for VDD and VDDQ and 1100 mV for VDD2 (MC Voltage).
