Summary and conclusion

The kit tested today is a perfect example of what can happen when specifications are omitted or even swept under the rug. Which ICs are installed, how they are organized, how many ranks a module has, all this information is simply not provided by most RAM manufacturers. Previously, with DDR5 it was largely possible to overlook this, simply because with 16 Gbit and 24 Gbit memory modules it could mostly be derived logically. However, since 32 Gbit ICs have been available, 32 GB modules can no longer be clearly identified as single-rank or dual-rank. Now recycled ICs with 8 Gbit are also being thrown onto the market and the chaos is complete. At this point, I would like to highlight Kingston as a positive counter-example, who are exemplary designating the rank organization of their modules and memory densities of the ICs used, and are thus a small but bright light in the vast, dark DRAM cosmos.

Aside from the gray area between package information and package contents, it is the actual measurable performance that is decisive. Here, it must be soberly acknowledged that these Patriot Viper Venom modules deliver very decent benchmark results despite their strange layout. Thanks to a relatively tight XMP profile of DDR5-6400 with timings 32-40-40-84 at 1.4 V, even kits with full 16 Gbit ICs and comparable profiles can be beaten regularly in synthetic benchmarks, but also in real gaming.

The overclocking potential is not bad either. Voltage and timings are similar to the full 16 Gbit A-Die chips from SK Hynix and thanks to the lower capacity of the ICs, tRFC can also be tightened even more. However, the total capacity is distributed over 2 ranks, so that on the one hand the relevant timings must be taken into account and on the other hand the maximum clock rate is also limited. 7200 Mbps can already not be booted. So this kit fits more or less by chance on an AM5 system if you want to stay in 1:1 mode (UCLK = MEMCLK) anyway. However, 2:1 mode or operation on an Intel platform with significantly higher clock rates is not really possible. Here we must also clearly warn that this 2x 16 GB DDR5-6400 CL32 kit does not behave like others. Although you get Hynix ICs, you don’t get the conventional clock-friendly variant, which can also be operated at DDR5-8000 without any problems.

Finally, I have to criticize the “cooling solution”. Yes, the ICs remain cool enough to ensure stable operation with the fastest XMP profile. Of course, Patriot also benefits from the fact that the half-defective ICs only produce half the waste heat and this is distributed over two sides of the module. But if we are honest, the aluminum strips with foam heat conducting pad are more of a high-gloss Gamer-style cladding than a functioning heat sink. No cooler at all would probably even result in better temperatures, but of course that would not provide the crucial e-sport grade placebo FPS.

Would you buy a pack of nachos if you knew in advance that every chip was broken in the middle? Sure, the contents of the bag of chips are correct in terms of quantity, but not in terms of quality. The answer for most of us is probably: no, or only if the deficit is clearly advertised and the price is adjusted accordingly.

If RAM manufacturers such as Corsair are being sued for the fact that the advertised XMP/EXPO clock rate on the package is not automatically applied at the first system start, what about the unmarked sale of recycled ICs? You buy a DDR5 kit with identical XMP/EXPO profiles to many other kits and potentially get B-grade goods. It’s nothing new that ICs in memory SKUs are often swapped between batches. As long as the memory chips can meet the specified timings, the cheapest component is often used. This is actually cold coffee. But if the capacity of the individual ICs and therefore the rank organization changes, that’s something else again. I’m not quite sure myself how critical this should be seen.

In principle, the recycling of partially defective memory chips is a good thing: less waste and more supply. But it should be described transparently for the end customer. It must also be said that not every Patriot Viper Venom 2x 16 GB kit has these SK Hynix 8 Gbit “H-Die” ICs installed. Patriot is also a renowned RAM manufacturer and I myself have often bought and recommended kits from this brand since the days of DDR4, mostly because of the very good price-performance ratio. But now you can no longer be sure that you will get full 16 Gbit ICs with any SKU. In addition to the SKU PVV532G640C32K tested today, PVV532G600C30K (EXPO DDR5-6000 CL30) also has the 8 Gbit H-Dies installed, according to my sources. In a way, Patriot has infiltrated its own product portfolio.

If you take it a step further, this would also be conceivable for other module sizes. For example, you could build a dual-rank 24 GB module from partially defective 24 Gbit ICs with usable 12 Gbit capacity. If you now put on your aluminum hat, you can no longer be sure with any RAM manufacturer that no recycling ICs will be foisted on you as long as the manufacturer does not clearly specify the capacity of the installed ICs per SKU. Fortunately, things are (still) different in reality, but in principle you can’t really be sure.

If you are only using AM5 anyway and don’t expect clock rates higher than 6400 Mbps, the kit tested today isn’t bad. However, as a buyer, you should be aware of what you are buying and at what price. At the moment, you can watch RAM prices exploding faster than paint drying. So at this time kits like the Patriot PVV532G640C32K may be able to relieve some pressure of the market by offering a cheaper alternative. But still one should expect a significantly lower price compared to kits with full 16 Gbit A-Die ICs.

The RAM kit was purchased privately as retail goods for the purpose of this test.
