Heatsink test
Our heat test will now show whether the module coolers not only look good, but can also fulfill their actual purpose well. By the way, the RGB LEDs with their not negligible waste heat remained on. The RAM stress test Testmem5 v0.12 with profile “Extreme1@Anta777” is used for this due to its extremely high heat load for the working memory. The temperature is recorded with type-K probes on the module with the memory ICs on the inside, logged at 0.5 second intervals, forming the delta to the room temperature.
On the one hand, we can test whether the modules are actually stable in XMP mode, and on the other hand, we gain an initial indicator of the cooler’s performance and the associated thermal potential for further overclocking. We test the modules once completely passively without any further cooling and a second time with a 2000 rpm 120 mm fan directly on the modules.
Compared to other RAM kits with similarly high XMP voltages, the Corsair Vengeance RGB module coolers are nothing special, but they do their job well. With about 40 °C in passive mode and about 6 °C with active cooling, both above the ambient temperature, there is enough breathing room to still function stably in a warm case. With the same ICs, the larger Dominator Platinum RGB modules perform better, but the operating voltage is another 100 mV lower.
SPD information
The information in the Topology Tab is well-known and nothing new for 16 GB DDR5 modules.
In the timings tab we find as always the officially supported JEDEC timings.
The manufacturers of the individual components are stored in the MfG tab. 80B3 at the manufacturer of the SPD EEPROM stands for Renesas, as you know. The PMIC manufacturer with identifier B10 is Anpec, which is also known to us from other DDR5 modules. The code 80CE now still reveals the manufacturer of the DRAM devices, namely Samsung. Stepping B matches this, so we are talking about Samsung 16 Gbit B-Die DDR5 ICs.
XMP profile there is only one, the one advertised in the specifications with DDR5-6000. The voltages are specified as 1800 mV VPP, 1350 mV VDD, 1350 mV VDDQ and 1200 mV MC or VDD2. The effective clock rate loves at 5996 Mbps with timings tCL 36, tRCD 36, tRP 36, tRAS 76, tRC 112, tWR 90, tRFC1 885, tRFC 480, and tRFC_SB 390. The command rate is not specified. As is currently common with DDR5, only one module per channel is supported – running two kits together is not.
The PMIC is a JEDEC PMIC, which is accordingly locked at 1.435 V VDD and VDDQ and therefor limits the overclocking potential. The Dynamic Memory Boost and Real-Time Memory Overclocking features are also supported. As mentioned, there are no other profiles in the SPD.
