Dimensions

At 136 mm, the modules are slightly longer than a DDR5 DIMM slot with a slight overhang of the latch on both sides. The height of the modules is 55.6 mm and 52 mm from the upper edge of the DIMM slot, respectively, if you want to check the compatibility with air coolers or radiators. The modules also dominate on the scales with 85 g each, which should pay off in the cooler’s heat test.

SPD information

The “DDR5 SPD” function of the Asus “Worktool” is again used to read out the SPD. The usual information for single-rank DDR5 modules can be found in the Topology tab. In summary, there are 2 subchannels of 32 bits each, to which 4 ICs with x8 bit organization are connected. In turn, the structure consists of 16 rows and 10 columns or 8 bank groups with 4 banks each.

In the timings tab we find the data of the ICs specified by the DRAM manufacturer for JEDEC. Here, the frequency is nominally specified as 4800 Mbps at timings tCL 40, tRCD 40, tRP 40, tRAS 77, tRC 117, tWR 72, tRFC1 708, tRFC2 384, and tRFC_SB 312. The tCL values supported here have no effect on the operation of the modules in our tests.

In the MfG tab we can find familiar faces or much more hex codes. 80B3 stands for the SPD manufacturer Renesas and B10 for the PMIC manufacturer ANPEC. The OEM for the boards is Brain Power with the code 29E. We already know the code of the DRAM manufacturer 80AD from the past review of the ADATA XPG Lancer modules, which also used Hynix M-Die chips. In contrast to these, however, the IC type or the DRAM stepping can be read out correctly as M here.

In the XMP 1 tab we can now find the full XMP profile and some more useful info. The PMIC is an “XMP (OC) PMIC”, so that officially higher voltages than 1.435 V can be set for VDD and VDDQ by its manufacturer. The recommended configuration of the kit is “1DPC”, which means 1 DIMM per channel, which should be noted especially for such high speeds as the 6200 Mbps of this kit. Also, two identical kits together on a 4-DIMM motherboard will not work with the XMP profile, even if some “techtubers” give this impression.

Unlike Teamgroup, Corsair specifies the VPP voltage at 1800 mV analogous to JEDEC. VDD and VDDQ are each set to 1300 mV and MC Voltage or VDD2 is set to 1200 mV. In addition to the frequency of DDR5-6201, the full timings of the XMP profile are tCL 36, tRCD 39, tRP 39, tRAS 76, tRC 115, tWR 93, tRFC1 915, tRFC2 497, and tRFC_SB 404, with the CMD rate not specified. Further XMP profiles are not stored.
