Final Words & Conclusion

The Zadak Spark 6000 CL40 kit offers users satisfying performance already out of the box. It looks nice; also, there’s RGB applicable, which looks attractive. The heat spreader comes in matte white with aluminum accents. The range of available frequencies is extensive. The slowest module in this series operates at 5200 MHz (a 2 x 8 GB kit), and the fastest one reaches 6400 MHz, and we checked a 6000 MHz variant in this review. Users should be satisfied with the Zadak offer. As with the others DDR5 kits, it is aimed only at Intel users (for now).



Zadak has made Spark attractive; at least, we can say that about the radiator. The RGB can be set lighting using the motherboard utilities. 



The memory chips used here come from Hynix. We achieved a nice tweaked CL38 with 6400 Mhz at 1.4 V (1.35 V is the baseline value). You can always lower the latencies further (CL32?) and leave the standard 6000 MHz frequency. Still, you’d better try to cool the memory down with some active cooling for the best results. As we usually state –the reproducibility of the overclocking capabilities is never guaranteed, and your results may vary.



The Zadak kit we checked provides a default frequency (6000 MHz) that will be enough for practically all users, and the XMP 3.0 profile makes life easier. The stock performance is in the expected range (very close to the high-end). There’s some headroom still available, so if you want more, you can try to overclock the memory even further (6400 CL38 was possible for our sample). The reviewed kit on our Z690 platform enabled it to achieve 6400 MHz with CL38. It’s a great result; remember that those are 16 GB modules. The not-so-low-profile heat spreader (50 mm), so you can encounter clearance problems with some air CPU coolers. The 32 GB option is a lot for most users nowadays. This 2 x 16 GB kit is ~330 USD, which is quite expensive compared to the DDR4 modules, but you must remember that it’s high-end RAM, and the direct competition is not necessarily cheaper. The current price for the DDR5s is very steep (mainly due to the shortage of the PMIC), and it still doesn’t look to be lower in the coming days. We can give Zadak a “Guru3D Approved” award for this fast, overclockable, capable kit. The temperature is good. But the price is still the main downside of such a high-end kit (same as most of the DDR5s). Most users won’t accept it at the moment. Especially when compared to the DDR4 kits, you’ll get not so much worse performance results (for now, at least compared to the current available DDR5 memories, probably it’ll look different with the Intel Raptor Lake or AMD AM5 CPUs, especially with frequencies above 6400-6600 MHz). Considering all aspects - we can grant the "Approved" award, thanks to the good performance/overclocking and temperatures.
