Polish DDR5 RAM? See if they make sense (Test)

How much do you have to pay to get efficient and solid DDR5 RAM? According to the Polish manufacturer, not much. The IRDM series modules, which we are taking on today, are proof of this. They will satisfy RGB LED opponents and fans of tower CPU coolers.

Most consumer electronics production (and not only) has long since moved to Asia. At first it was China, but now the trend points to countries like India and Vietnam. The reason? It’s cheaper. Fortunately, there are exceptions to this rule, and one of them is in the country. I’m talking about the company Wilk Elektronik S.A.., better known through brands such as GOODRAM and IRDM. Poles specialize in memory – SSDs, RAM modules, pendrives, memory cards. We are talking about low, medium and high price-performance shelf for consumer and industrial segment.

IRDM DDR5 is available in 32 and 64 GB kits

Today we will be discussing RAM memory, or more precisely the model IRDM DDR5. These are desktop modules aimed at gamers. They fit both Intel and AMD platforms, as they are equipped with profiles Intel XMP3.0 and AMD EXPO. It fell into our hands 32 GB kit (2x 16 GB) which works at a speed of 6800MT/swith delays of the order of CL 34-40-40-80 and tension 1.45V. The focus here is clearly on a good price-performance ratio. This is currently the cheapest set with this specification.

When it comes to the construction itself, we are talking about black PCB and a simple aluminum radiator in the same color. There is no RGB LED backlight herebut there is a slightly more expensive version available with this convenience. The memory chips used come from the South Korean SK hynix. The overall quality of workmanship is very good, but the plates are thinner than, for example, G.SKILL’s, and PMIC system does not have a thermal pad.

Platform and Test Procedure

The editorial test platform Telepolis consists of high-end components. So we are prepared for almost everything that manufacturers have prepared for the consumer market. The computer is based on the top model of the Intel Raptor Lake Refresh processor family (14th generation). The exact specification is as follows:

Processor: Intel Core i9-14900K
Motherboard: MSI MEG Z690 UNIFY
Graphics Card: GIGABYTE AORUS GeForce RTX 4080 16GB MASTER
SSD: ADATA XPG GAMMIX S70 Blade
Charger: Cooler Master MWE Gold V2 1050W
Case: Fractal North XL
Cooling: Arctic Liquid Freezer II 360 A-RGB
Thermal paste: SilentiumPC Pactum PT-4

We always run our tests on the current Windows 10 system. Background programs are limited to the bare minimumand component management applications are disabled. This is to ensure constant measurement conditions and eliminate variables. Each test is performed several times (5 to 10 times) and then an average value is taken.

For the measurements we used popular and proven programs in their latest versions, namely: 3DMark, AIDA64, 7-Zip, Cinebench 2024. In addition, there were practical tests using well-known AAA games.

Speed Measurements – AIDA64 Extreme

We start testing the IRDM DDR5 series with the program AIDA64 Extreme. In the menu on the top bar, the “Cache and memory performance test” is hidden. It allows you to quickly and easily check the speed of reading, writing and copying. There is also no shortage of delays expressed in nanoseconds.

Of course, as you can easily guess the higher the effective clock speed and the lower the latency, the better the transfers we get. Meaning that IRDM DDR5 came first in our measurements. It is worth remembering, however, that it is not always worth chasing MHz alone, and sometimes it is better to bet on lower CL. The golden mean usually offers us the best performance, price and compatibility – not every motherboard and processor will support fast RAM. Also in terms of latency, the tested IRDM DDR5 modules perform very well.

Synthetic test – 3DMark Time Spy

3DMark is a popular testing program that offers several different scenarios. It allows you to test both high-end and low-end computer sets; based on newer and older components. It is therefore often used by ordinary consumers, enthusiasts and professional overclockers. It puts a strain on both the GPU, CPU and RAM, simulating situations found in AAA games. It also allows you to detect stability problems.

Once again, the tested IRDM DDR5 memories come out on top. It is worth noting, however, that the difference to G.SKILL Trident Z is small – only 1.6% efficiency. Why, when the clocks are 13% lower in the Taiwanese? The reason is simple – tighter (lower) timings. Some tasks prefer high MT/s, others low CL, but as was said earlier – a sensible balance of both of these parameters is best.

Synthetic test – Cinebench R23

The next test program we used was Cinebench 2024. This is a newer version of the well-known benchmark from the German company Maxon, based on the engine Maxon One used to create 3D graphics. We have three tests to choose from to check GPU and CPU performance in single or multi-threaded tasks with the result expressed in points, each lasts about 10 minutes. The obtained result can be easily compared with the results of other users.

We will skip single-threaded performance tests today – the differences are marginal, at the level of measurement error (1-3 pt). In the case of multi-threaded performance, the distance between the slowest and the fastest memories is greater. This is the first time IRDM DDR5 narrowly loses to Taiwanese proposal from G.SKILL. The difference is not big though. What the Poles lose in delays is made up for in timing.

Practice Test – 7-Zip

7-Zip is a free, open-source program that is available on operating systems such as Windows, Linux, and MacOS. In other words, it is simply an archiver, an alternative to the paid WinRAR. In addition to creating and unpacking archives in many different formats (including its own – *.7z), it also offers a built-in benchmark. You can find it on the top bar in the “Tools” -> “Performance Test” tab. We used a 32 MB dictionary and all threads available in our case (32).

The compression test depends on the RAM module latencies, but also on the size and speed of the cache. In the case of the decompression test, the processor is the main player, but the RAM modules used still have a lot to say. Therefore, IRDM DDR5 is only about 8% faster in decompression than the slowest DDR5 RAM modules on the market. However, in the case of decompression, we are talking about a difference of as much as 28%. What’s more, it manages to overtake the G.SKILL 6000 MHz again, but only slightly.

Practice Tests – Games

In the case of games, we decided on two extremely different productions. One is a popular and extensive turn-based strategy from 2022, which is Total War: Warhammer III. The second is the domestic action RPG from 2020, Cyberpunk 2077. Both games can put a serious strain on the processor. In the first case, this is especially visible in the case of battles with large armies. In the second, locations with many NPCs and extensive scenery work best. In both cases the tests were conducted in Full HD resolution.

The benefits of faster RAM in Cyberpunk 2077 are obvious at first glance and you don’t even need to look for a special test site here. The differences between IRDM DDR5 and basic DDR5-4800 memories are about 9%. It may not seem like much, but remember that we’re still talking about the same graphics card and processor. When using a weaker GPU, it can be the difference between “playable” and “unplayable”. Total War: Warhammer III is definitely less sensitive to RAM. We’re talking about a difference of a few FPS at best, so it’s not worth the time to even look at the graph. The only exception is battlesbut mostly solo and late game ones.

Summary and evaluation

IRDM DDR5 are solid RAM modules for the average consumer. It’s hard to fault them for anything and they offer exactly what the manufacturer promises – a good price-performance ratio. I’m not talking about top specifications or huge capacities here. In return, however, they will be supported by virtually all 12th, 13th and 14th generation Intel Core processors available on the market, as well as AMD Ryzen 7000 and dedicated motherboards with LGA 1700 and AM5 sockets.

For many people, a big advantage may be the fact that they are assembled in Poland on branded components – the dice are South Korean SK hynix. I have to disappoint the enthusiasts that at least in the case of our set the OC potential is small. Even at 7000 MT/s there were stability issues, but you can play around with the timings a bit – although there’s nothing great here either, mostly cosmetic. There is no problem with high temperatures herewhich reached a maximum of 48°C.

IRDM DDR5 currently costs in Poland about 549 zlotysmaking them the cheapest 32GB DDR5-6800 modules on the market. At least when it comes to new hardware without any promotions. They are covered by the traditional, lifetime manufacturer warrantyIn my opinion they are definitely worth the money and it is definitely better to choose them over the slightly cheaper DDR5-4800 or DDR5-5200 options. They will work well in both gaming and work PCs.
