Review of the GoodRAM IRDM Pro IRP-K3600D4V64L18/32GDC memory kit. How much can be squeezed out of “iridium”?

GoodRAM IRDM Pro is a product of the Polish company Wilk Elektronik for gamers and enthusiasts, which has been distributed in Ukraine for a long time. RAM kits of this line have proven themselves as completely original products that have a tendency to “shoot” sharply and unexpectedly, just for fans to squeeze the maximum out of their own resources in the presence of free time, and not to spend money on flagship components. For those who want to save even more, there is a simple IRDM. This time we will talk about the IRDM Pro IRP-K3600D4V64L18/32GDC kit.

GoodRAM IRDM Pro IRP-K3600D4V64L18/32GDC

The kit is supplied in two paired plastic blisters. The volume of the set, frequency, timings, two-channel mode and even the memory rank are indicated on the front. Everything you need for a quick selection in the store, if you do not take into account the tension of the XMP-profile, but the manufacturer was so close to the ideal.

Inside there are two identical strips, no stickers or accompanying documentation are provided.

Memory bars are made in a minimalist style in a dark color scheme. Black textolite, black matte radiator with black glossy symbols of the IRDM Pro line. In general, everything is black, even if it is a little different.

On one of the sides there is a sticker with the P/N of the product, the volume of the memory stick and the voltage of the XMP profile.

The radiator is not thin enough to deform from a strong grip, but not thick enough to accommodate ribs in its design. Therefore, although its presence is not a decorative function, you cannot call it a full-fledged assistant in cooling either.

This is how the bar looks without a radiator:

The manufacturer has kept the original marking of microcircuits. SEC K4A8G045WD-BCVF chips, frequent guests in OEM Samsung bars on black and green textolite, are crowded under the radiators. They are soldered on both sides of the textolite.

Test stands and methodology

Intel LGA1200:

• processor: Intel Core i9-11900K;
• cooling: SVO circuit (EK-Supremacy water block — Acetal + Nickel);
• thermal interface: Arctic Cooling MX-4;
• motherboard: Asus Rog Maximus XIII Hero (UEFI 1204);
• video card: GeForce GT 1030;
• system drive: Kingston KC3000 1TB (SKC3000S/1024G);
• power supply unit: Rosewill Hercules-1600S (1600 W).

The temperature in the room was 20 degrees Celsius. Fan speed control is automatic. The frequency potential of the RAM was investigated by voltage steps of 0.025 V, and single frequency increases/decreases or timings for the next step, the system stability was checked by a set of loads in the form of a LinX run (problem size 32717, 8 GB, 10 iterations), as well as passing Y- cruncher on the Pi-1b preset. Each benchmark was run five times, the arithmetic mean is indicated in the results. The LGA1200 platform operated at a static processor frequency of 5 GHz on all cores (processor voltage 1.3 V), the cache (Ring) operated at a frequency of 4.5 GHz, consumption limits were removed. Tests were performed on Windows 11 Pro x64 21H1 OS (with current updates as of February 2022).

Testing

Thaiphoon Burner outputs the following information about the IRDM kit:

It can be seen that GoodRAM did not bother too much with the correctness of the information, however, in its weight category, this can be forgiven. AIDA64:

The frequency limit was 3882 MHz with a voltage of 1.6 V and CL20 timings. But it is worth noting the good scalability of the voltage, it is worth applying a voltage of 1.65 V to the set, or even higher (the scalability stopped at the level of 1.95 V) – you can get a very good 3600@CL14, but in terms of frequency, the same not impressive 4000 MHz. They are not included in the graph because they are dangerous under constant voltage. However, if the owner of such a kit suddenly turns out to be a poor but risky overclocker, why not?

An example of the gap between the XMP profile and the manual setting is below, the screenshots contain all the important information:

We proceed to detailed testing in “synthetics” and, according to tradition, AIDA64 opens the hit parade of graphs:

An average gain of 4% in throughput, as well as a 12% reduction in latency.

In archiving tasks, you can expect an 11% overclocking advantage.

Geekbench gives a 6% higher estimate of the RAM node in overclocking against the background of factory XMP.

Y-cruncher is 5% faster thanks to fine-tuning of the memory kit.

Conclusions

The Polish company Wilk Elektronik continues to fight for the buyer’s wallets. Low-profile radiators guarantee an almost complete absence of compatibility problems with large-sized coolers, and together with an interesting design that does not “shout”, make it a good option for literally any system. The lifetime warranty on the kit cannot fail to inspire confidence, but the statement about “premium memory chips” is not entirely true, because these are Samsung OEM chips from which almost all the juices have been squeezed by the manufacturer. The test set was slightly overclocked in terms of frequency, but it was able to squeeze in the timings quite decently and show an 8% advantage on average over the XMP profile, which means that it is ideal for Gear 1 of the already outdated Rocket Lake on the LGA1200 platform, and will fit well into a modern Alder-based system with DDR4 memory.
