Patriot Viper Xtreme 5 RGB 48GB DDR5-8000 Memory Kit Review

Patriot is expanding its memory line with faster DDR5 memory kits, so we also try to keep up and show you the latest and fastest they have to offer. Today, we present the Viper Xtreme 5 RGB with 48GB capacity and rated at 8000MT/s. It seems to be the most interesting memory kit for avid gamers as it’s one of the fastest options, available at a higher capacity, and is still reasonably priced.

The memory kit is designed for the latest Intel chipsets and supports XMP, so our tests will be performed on the ASUS Maximus Z790 APEX motherboard, which shouldn’t limit the hidden potential of the Xtreme 5 memory kit. I won’t make this introduction any longer as there are more exciting things to look forward to. Let’s start with specifications and features so we know more details about the tested memory kit.

Specifications

The tested memory kit contains two memory modules, 24GB each, so 48GB in total. Even if it seems too much right now, new applications and background services are getting more memory-hungry, and the price difference between 32GB and 48GB memory kits isn’t much. I find 48GB just right as with multiple web browser tabs open, a game, and additional software, I was already reaching 32GB on my daily PC. Of course, most gamers can live with 32GB. We already reviewed Patriot Xtreme 5 at 32GB capacity and 8000MT/s so that you may look at our previous results.

Current memory kits that use 24GB modules overclock as high as those with 16GB modules, what’s another reason why non-binary memory kits are getting popular. All motherboards with the latest chipsets should support non-binary memory, as BIOS updates were released a few months ago.

Unsurprisingly, the Patriot Xtreme 5 DDR5-8000 uses the new Hynix M-die IC, the only IC used in higher frequency 24GB and 48GB memory modules. In low-frequency memory kits, we can also find Micron IC, but I highly doubt that Patriot will use Micron IC in the Xtreme 5 memory series anytime soon. In short, we can be sure that the Xtreme 5 series is based on the best overclocking IC available in stores.

The Viper Xtreme 5 is compatible with most motherboards on the market that officially support DDR5-8000. It also works with some series that are rated lower, like MSI Z790 ACE MAX. What’s more, it also works fine on many AMD B650/X670 motherboards like ASUS Crosshair X670E GENE, Strix B650I Gaming, Gigabyte B650E Master or ASRock B650E PG-ITX. We took the time to check all the mentioned motherboards.

All the product specifications and features come from Patriot, and you can also find them on the product website.

Patriot uses about the tightest timings for available 2x24GB DDR5-8000 memory kits. The voltage is more standard as most competitive brands also use 1.45V. Those who use lower voltages also relax timings. The quick conclusion is that you can’t get anything faster rated at 8000MT/s.
Below is a list of timings that our ASUS APEX sets for XMP #1 with the XMP II option enabled in BIOS (default XMP timing table without tweaking).

Packaging and Product Photos

The memory kit arrived in an already well-known Viper series package. It’s a bit thicker than a typical RAM package, but in general, it’s a small, flat box. On the front, we will see a picture of the memory kit and a highlighted memory speed and capacity. On the back are typical product and serial numbers, various certificate logos, and contact to support (which we expect won’t ever be needed).

We will find two memory modules and a sticker with the Viper Gaming logo inside the package. We don’t need much, and memory installation manuals always have motherboards. I assume anyone buying this type of memory already knows how to install it.

The memory kit arrived in perfect condition, as seen in the attached photos. As simple as the blister protection seems, it’s enough to keep modules safe. The package was additionally well protected with another box. Some vendors send samples in simple plastic bags, and so far, every memory kit has been in good condition. It just proves that the popular blister protection is better than it seems.

The memory modules look exactly the same as in our previous Viper Xtreme 5 review, where the memory kit used two 16GB modules. This time, the general specifications are similar, with one significant change: memory capacity. The memory kit tested in this review uses two 24GB, non-binary memory modules. Most new and high-frequency memory kits use the same type of memory chips. Every DDR5-7200 or higher memory kit also uses Hynix IC. The main difference is in the chip binning, as not every kit will make 8000MT/s. Some will require higher voltages or more relaxed timings. Patriot sticks with tight timings and still reasonable voltages, so our memory kit comes with a CL38-48-48 1.45V VDD/VDDQ general specs.

Memory modules are protected by aluminum heatsinks, which are quite thick. The design is quite simple but also looks well on every motherboard. The top bars are semi-transparent, so the RGB illumination goes through, and we can’t count the LEDs. This is important as on many competitive memory kits, we can clearly see brighter spots where LEDs are installed, and it does not always look well.

RGB Illumination

As usual, we had no problems with the RGB illumination and setting of various modes. The Viper Xtreme 5 is fully supported by all leading motherboard brands, including ASRock, ASUS, Gigabyte, MSI, or less popular ones like Biostar or Colorful. We can use Patriot software, widely described in our previous Patriot reviews if there is any issue. Either way, we are sure that the RGB illumination will work, even on the least popular motherboard.

The light bar looks fantastic, regardless of whether we use a single static color or the dynamic rainbow mode. On our test rig, the best look is a white backlight. Still, the big advantage of a white PC interior is that it reflects all colors, so we can turn it into whatever we want using lights instead of spending money on specific colorful components.

Let’s move to performance tests.

Test Results

The test setup has been changed since the last memory review. The Radeon RX6800XT graphics card has been replaced with the Colorful RTX4080 Advanced OC. The CPU was slightly improved from the i7-13700K to i7-14700K. Since these changes significantly affect test scores, then, of course, the comparison is refreshed, too.

Stability at Rated Speed

The AIDA64 System Stability Test tested the XMP profile and passed without problems.

The memory kit passed more extended stability tests at XMP settings on the ASUS Z790 APEX motherboard. There were no problems during various tests, while the main difference is further overclocking, for which I highly recommend the ASUS Maximus Z790 Apex or other top series motherboards.

Even though the reviewed memory kit is designed for Intel motherboards, an additional test was performed on AMD Ryzen 7000 setups, and the memory kit passed all tests without problems at XMP settings. The Viper Xtreme 5 DDR5-8000 probably isn’t on any AMD motherboard QVL, but I thought it’s worth mentioning, as high memory frequencies are getting more popular with the latest AMD processors.

If we have any problems with stability at DDR5-8000, then we can use one of the remaining XMP profiles at DDR5-7600 or DDR5-7800. All of them provide high performance.

Comparison Tests

Tests were performed on popular synthetic benchmarks and benchmarks included in popular games. The list consists of tests that react well to memory performance. Older popular benchmarks and tests based on pure CPU performance were skipped as we wouldn’t see any difference. For readers’ convenience, I added the overclocking result for comparison so you can see if it’s worth the overclocking.

Benchmarks list includes:

• AIDA64 Cache & Memory Benchmark
• Blender 4.0.0
• Cinebench 2024
• PCMark 10 – Applications Benchmark
• 3DMark: Time Spy, Time Spy Extreme, and Fire Strike Extreme
• Superposition Benchmark – 8K Optimized
• Final Fantasy XV Benchmark – 4K High Details
• Shadow of the Tomb Raider – 1080p, high details, default benchmark
• Far Cry 6 – 1440p, high details, default benchmark
• Assassin’s Creed Valhalla – 1440p, high details, default benchmark 

AIDA64 Cache & Memory Benchmark

AIDA64 Memory and Cache Benchmark is probably the most popular software to measure RAM bandwidth and latency.

The maximum bandwidth depends on the motherboard and CPU used, but we can count that the Viper Xtreme 5 DDR5-8000 will give us anything between 115GB/s and 120GB/s at the XMP profile. The average latency in AIDA64 is around 60 ns. 32GB kits usually have slightly lower latency and slightly higher maximum bandwidth. However, here, we get a higher memory capacity, which may affect our experience if we run many additional tasks in the background.

Blender 4.0.0

Blender is one of two benchmarks added after refreshing the test platform. We can see that rendering tasks react well to RAM performance, but it’s scaling the best up to DDR5-7200. Above this point, we can see the performance gain, but it’s not as spectacular as anything between DDR5-5600 and DDR5-7200.

Cinebench 2024

We can see about the same in Cinebench 2024, which is also a new addition to the comparison. One more rendering benchmark that reacts well to RAM performance. The Xtreme 5 memory kit at 8000MT/s is very close to 8200MT/s or even overclocked 8600MT/s settings.

PCMark10 Applications

PCMark 10 tests have been changed from a general score to an Applications benchmark score. Excel and Edge tests react much better to RAM speed than other tests, and we can see it in our comparison. The main difference between this test and rendering benchmarks before is the scaling all the way up to 8600MT/s. Even though we can see that the biggest gap is between DDR5-6000 and DDR5-7200, the score is going up to the top of the list with visible gains. The Xtreme 5 memory kit at 8000MT/s is again not far from the best score on the list.

3DMark – Time Spy

3DMark series benchmarks show better results at higher memory frequency, with a 1600-mark difference between the slowest and fastest RAM profiles. The XMP setting of the Xtreme 5 8000MT/s is not far behind the 8200MT/s kits. One more time, the platform scaling is already slowing down above DDR5-7200.

3DMark – Time Spy Extreme

In the Time Spy Extreme benchmark, the performance gain from RAM itself is not so visible. We can still tell which memory kit is the fastest, and the list looks about the same as in other tests. However, differences are insignificant, and the highest step is from DDR5-5600 to DDR5-6000. The Xtreme 5 memory performs nearly the same at 8000MT/s as other kits at 8200MT/s or overclocked 8600MT/s.

3DMark – Fire Strike Extreme

The same story tells Fire Strike Extreme. The performance gains at higher memory settings are nearly the same as in the Time Spy Extreme benchmark.

Unigine Superposition

The same is true in the Superposition benchmark; the results at the XMP profile and overclocked settings are not much different. At high display resolutions, we barely see the performance difference. Most games still can’t use improved RAM performance, but more often, we can see titles that use more RAM and manage it better for higher FPS.

Final Fantasy XV Benchmark

Final Fantasy XV is an older benchmark that reacts similarly to most other 3D benchmarks. The only surprise is that the DDR5-6400 memory achieves better results than the DDR5-7200. The Viper Xtreme 5 8000MT/s memory keeps the solid spot just after 8200MT/s kits, but the difference is barely visible.

Shadow Of The Tomb Raider

Shadow of The Tomb Raider is already quite an old game, but it received a lot of updates that let it be popular for longer. It’s perfect to show the performance gain at lower display resolutions like 1080p. The high preset gives us nearly 40FPS gain between a standard speed, Crucial Pro DDR5-5600 memory series, and the Viper Xtreme 5 DDR5-8000. It’s an incredible difference because of only RAM speed. Once we push it some more, then we can get an additional 8-10FPS.

Far Cry 6

In more demanding games or games at a higher display resolution, the performance gain from fast RAM is not so visible but still notable. In the Far Cry 6 benchmark, we could see exactly a 15FPS gain going from the slowest RAM in the comparison to the Xtreme 5 memory at 8000MT/s. Additional 5FPS were possible with further overclocking.

Assassin’s Creed Valhalla

Assassin’s Creed Valhalla gains are not so spectacular, but they still look good. The Viper Xtreme 5 gives us 7FPS more than a standard memory.

Overclocking

Temperatures and Voltages

Viper Xtreme 5 is top-quality memory with premium PCB, high-binned IC, optimal PMIC for overclocking, and well-performing high-surface heatsinks. Temperatures are not the best we’ve seen but are also lower than many other competitive memory kits. Either way, I recommend good airflow in the PC case, as it may affect our RAM’s stability and overclocking potential.

As in previous reviews, we went up to 1.55V during the overclocking tests, and the temperatures were still acceptable, considering that RAM was not generating errors because of the temperature. The DDR5-8600 setting isn’t entirely stable because of the test platform limits. However, if you have a very strong CPU and motherboard, then you can count it will easily reach 8600MT/s or even more.

If we won’t overclock the memory kit and use the XMP profiles, we can expect around 65°C during gaming or more demanding but still mixed load work.

I’m not recommending anything above 1.45V for daily overclocking, including games, as the performance gain at tighter timings or higher frequency won’t be apparent. Too high temperatures or voltages may cause random errors, even though memory may pass popular stability tests.

DDR5-8600 CL38-52-52-98 1.55V

On our test platform, we could reach the DDR5-8600 at still tight timings of CL38-52-52-98. The required voltage for the DDR5-8600 was around 1.55V, which, for the tested memory kit, isn’t a problem. The screenshot with the mentioned settings is below. It does not include additional fine-tuning, so if we spend more time, we can easily pass 130GB/s bandwidth and go close to 50ns latency. These results were not checked in stability tests but passed all the benchmarks on the comparison list and others not listed. As I mentioned, because of the test platform limits, it’s highly possible that these settings can be stabilized on a better memory controller or motherboard.

Lower timings are possible at higher voltages, but the performance gain is barely visible, even in synthetic tests, so it’s not worth pushing it for anything but competitive benchmarking. For gamers, the XMP profiles are still optimal and provide high performance.
The 8000MT/s speed is just right for most higher Z790 motherboards, but also AMD B650E/X670E motherboards. It is surprisingly easy to stabilize AMD at 8000MT/s with the latest AGESA, but it won’t go any higher. On Intel, we have a chance to go up as long as the memory controller and motherboard let us.

Because of the mentioned test platform limitations, we could set about the same maximum frequency and timings as on the 8200MT/s kit, even though the higher-rated kit has even better memory chips. The Viper Xtreme 5 8200MT/s will be reviewed soon, so visit the front page in the upcoming days.

If you are into overclocking, feel free to share your results on our forums.

Conclusion

We already knew the Viper Xtreme 5 RGB would be a good memory kit as we had a lower-capacity kit from the same series. The main question was how it acts at the higher capacity and how well it is overclocking. We can confirm that regardless of the capacity, you can count on the best memory IC under the heatsinks and high-quality design. The memory kit looks fantastic and works exceptionally well on various motherboards.

The overclocking isn’t counted to the verdict, but it’s important, especially though we are on Overclockers. The 8600MT/s is more than any brand sells in stores. It’s also more than most motherboards support. It was at the edge of stability for our test rig. Still, the final results prove that Patriot released a fantastic memory kit with very high overclocking potential, which matches the Xtreme naming of the product.

DDR5 memory kits are getting cheaper, so higher overclocking series are at a reasonable price right now. Patriot was never an expensive brand; this time, we can count on it being cheaper than the competition. The 48GB DDR5-8000 RGB memory kit costs around $260 in the Patriot online store. Most competitive 32GB DDR5-8000 kits cost about as much.

It can’t be any different. The Viper Xtreme 5 RGB 48GB DDR5-8000 receives our Approved Stamp as a top-quality, high-stability RAM with high overclocking potential and still not expensive. I’m sure anyone who decides on this memory kit will be delighted as it gives high performance and a lot of fun to anyone who is into overclocking or computer modding.
