Review: 48 GB Patriot Viper Xtreme 5 8200 MT/s CL38

It’s definitely the 48 GB kits equipped with the new Hynix M-die chips that are currently the rage in our lab, as today we’ll be reviewing the 48 GB Patriot Viper Xtreme 5 kit, clocked at 8200 MT/s CL38. Following on from our tests of the Teamgroup T-Force Xtreem 8200 MT/s CL38 and Corsair Dominator Titanium 8000 MT/s CL38 memory kits, we now turn our attention to a Patriot model. We’re particularly pleased to be able to offer you this test, since it’s the first time we’ve collaborated with the Patriot brand! We’d like to take this opportunity to thank Shannon Robb for this kit. In fact, it’s the fastest kit currently available in the brand’s catalog.

As a reminder, our test platform has evolved to include the Maximus Z790 APEX ENCORE motherboard and our i9-13900KS, which boasts an excellent IMC. Our previous tests are still available, but we’ve chosen to run only a few kits at reference frequencies in the first instance. The idea is to have at least one kit per frequency in order to have a sufficient panel. I’ll be adding the other previously tested kits in the weeks to come.

What’s more, since the arrival of the Hynix A-die and the new Hynix M-die chips several months ago, frequencies have risen sharply, requiring a test configuration capable of supporting these XMPs and, of course, overclocking.

Don’t hesitate to ask us any questions you may have, either in comments or on our social networks. You can also join our community on the discord. We’d also like to take this opportunity to thank Patriot for supporting this test.

We take stock of the kits available to us:

[nextpage title=”Packaging description:”]

Our Patriot Viper Xtreme 5 packaging:

Patriot’s kit comes in a cardboard box with a sober color code, featuring the two memory sticks in a light veil of smoke. Our sample of the day is part of the “Xtreme 5” series, which is also available in an RGB version. The brand highlights the kit’s distinctive design on the front panel. On the back, there’s also a label informing future purchasers of the characteristics of their memory kit. Two cut-outs reveal the backs of the two memory modules.

There are other references in the “Xtreme 5” series, with a kit in 7600 MT/s, 7800 MT/s, 8000 MT/s and 8200 MT/s available in 2 x 16 GB or 2 x 24 GB. A special feature of Patriot is the 8200 MT/s kit in 2 x 16 GB. As far as we know, it’s the only brand to do so.

Features and cooling :

Our kit is clocked at 8200 MT/s, has timings of 38-48-48-84 and requires a voltage of 1.45 volts to operate. It consists of two 24 GB modules for a total of 48 GB. The aluminum heat sinks are full matte black, but the top part is an aggressive red. Patriot also offers an RGB version for those tempted to add backlighting to their PCs.

Heatspreaders are responsible for dissipating heat from the PCB and memory chips. The look of the heat spreaders is very special, unique and unusual. The first side features a snake-shaped logo and the “Xtreme 5” series reference.

On the second side, the same part number, but with a label detailing all the features of our kit. You’ll find more details on the next page. The dimensions of the Patriot Xtreme 5 are 44 x 135 x 60 mm. As far as pricing is concerned, we haven’t yet managed to find it listed in Europe, even though Patriot has a factory in Holland. The only price we’ve found is $239.99 on the brand’s American shop, but it’s out of stock.

To conclude this presentation, please note that the kit is XMP 3.0(Extreme Memory Profile) compatible and comes with a lifetime warranty. So don’t forget to activate the profile directly via our motherboards’ BIOS.

[nextpage title=”How to identify your memory kit:”]

Basic features :

You’re going to tell me that this is pretty easy, since all you have to do is look at the references advertised by the manufacturer. Yes, but that’s not enough, especially if you’re planning to overclock it! Some information is given by the manufacturer, but you’ll have to dig around or even remove the heat sinks to find out the rest.

One side of the heatsink bears the inscription “Xtreme 5” and a label with the technical specifications of our example: “PVX548G82C38K”. The kit reference can be read as follows. The “P” stands for Patriot, the “VX5” for Viper Xtreme 5, the “48G” for 48 GB capacity, the “82” for 8200 MT/s frequency, the “C38” for CL38 timing and finally, the “K” for dual kit. For example, in the case of our copy of the day, this is the information we know.

  • Brand: Patriot
  • Model: Viper Xtreme 5
  • Capacity: 2 x 24 GB
  • Frequency: 8200 MT/s
  • Timings: 38-48-48-84
  • Voltage : 1.45 volts
  • Review: –

In order to get an idea of the overclocking potential of your kit, this information is insufficient and you’ll need to go further. It’s also very important to know the revision of the PCB and the model of the chips used in your memory kit. Depending on this information, the kit’s overclocking performance will be very different.

To find this information, there is currently only one solution: disassemble the heat sinks. The Taiphoon Burner software does not currently support DDR5 kits. Nor is there any indication that this will be the case in the coming weeks.

CPU-Z always present :

Fortunately, our trusty CPU-Z software is still at work, enabling us to verify this information, particularly with regard to the type of chips used in our kit. At present, there are three types of chip: Samsung, Hynix and Micron.

Our kit is perfectly recognized under Windows 10 and the various timings perfectly read. The memory chips used in our kit are Hynix. These are the chips with the best overclocking potential. But something catches our eye: the CPU-Z SPD tab shows us several profiles in addition to the basic 8200 MT/s profile. So let’s reboot our PC to see if this profile is actually present in the BIOS.

Our memory kit PCB :

Our kit therefore benefits from 3 GB chips, of which there are 8. As the “M” in the part number stipulates, we’re here on Hynix M-die and not A-die, but this is a new generation which further improves frequency rise. Our kit is an “SR” model for single rank, meaning that all the chips are on a single side. On the other hand, there are “DR” kits for dual rank , with chips on both sides of the PCB.

[nextpage title=”The importance of the XMP profile:”]

BIOS settings :

We can’t stress this enough, but your memory kit ‘s parameters are not automatically set once you’ve installed it. If this is the case for your processor, it’s not so for your memory kit, and you’ll need to go through the BIOS! This is what we had to do with our Maximus Z790 APEX to get the BIOS to load the XMP profile.

You can then configure it manually, choosing the right frequency, timings and voltage for your kit. For ease of use, we advise you to activate XMP (Intel) or EXPO (AMD) mode in ” AI Overclock Tuner ” to set it up automatically.

Without this, your performance will be impacted in all areas, and you’ll end up with a kit that doesn’t exceed the CL40 frequency of 4800 MHz. Performance will then be extremely limited. So let’s activate our XMP profile directly in the BIOS. As you can see, two other profiles are also available at 8000 and 7800 MT/s. Finally, this could be interesting for those who don’t have a configuration capable of holding the 8200 MT/s XMP. They could then use a lower XMP.

ROG BIOS, whether on the APEX or Crosshair models, benefit from memory profiles. They are a good basis for overclocking your memory kit. We’ll start by using them in our overclocking tests. Our kit is now set up in the BIOS and will work with the manufacturer’s specifications.

As you can see from the screenshots above, once the XMP profile has been activated, the settings are automatically detected. The frequency is set to 8200 MT/s, timings 38-48-48-84 are activated and the voltage is increased to 1.45 volts.

[nextpage title=”Intel configuration test:”]

Of course, this kit will only be tested on an Intel platform, as our comparisons have been based on this configuration from the outset. We’ve naturally opted for the ROG Maximus Z790 APEX motherboard, but we’re also testing the latest refresh model in parallel , the ROG Maximus Z790 APEX Encore version.

  • Motherboard: ROG Maximus Z790 APEX (BIOS 0084) APEX ENCORE (BIOS 0070)
  • Processor: Intel i9-13900KS
  • Memory : Patriot Viper Xtreme 5 clocked at 8200 MT/s CL38
  • Graphics card: MSI GT 710
  • SSD: Western Digital SN850 NVMe SSD M.2
  • Power supply: be quiet! Dark Power PRO 12 1500w
  • Operating system: Windows 10 64-bit (22H2)

We also decided to stick with Windows 10 (22h2), as it proved to be a better performer, especially for overclocking. We’ve noticed a significant drop in processor and memory performance since the latest Windows 11 updates, which sometimes distorts the results. Our benchmarks are run a minimum of three times, and the result is the average of these scores.

Aida 64:

This is a program that can provide you with a wealth of information about your configuration, but above all it has a memory benchmark. This calculates the read, write and copy speeds, as well as the latency, of your memory kit. It is often used to compare memory kits. It’s an excellent tool if you want to compare the performance of your memory kit with those we’ve already tested.

The version used for testing is 6.92.6603 beta, and we’ve used the performance of previously tested kits.

The performance of this first test is exactly what we expected. It’s off to a great start, with a read throughput of 126,230 MB/s for our XMP profile at 8200 MT/s. This is quite logical, since this Patriot Xtreme 5 kit combines high frequency with fairly tight timings . So, on an Intel platform, you’ll need to give priority to frequency and tight timings.

The same applies to write speeds, which are very good, reaching 123,473 MB/s with 8200 MT/s CL38. The logic of the graph remains identical to the previous one. The Corsair Dominator Platinum 4800 MT/s CL19 in DDR4 achieved 67,251 MB/s. Once again, we note a logical progression between the different kits according to their frequency and timing.

The findings are identical in copy, with once again the same duo at the top of our graph. The Corsair Dominator Platinum 4800 MT/s CL19 in DDR4 achieved a copy speed of 57330 MB/s. As you can see, it’s in reading and copying that DDR5 takes a clear lead over DDR4. Note also the difference between a DDR5 kit at 4800 MT/s (72,415 MB/s) and our kit at 8400 MT/s (123,193 MT/s). If we hadn’t activated our XMP profile in the BIOS, our kit, although sold as an 8200 MT/s model, would really have been clocked at 4800 MT/s. A reminder of the importance of enabling the XMP profile in the BIOS.

Finally, latency. This is the value on which all eyes are focused, as DDR5 lags a little behind. Our best DDR4 kit in this respect was the G.SKill Trident Z Royal Elite 4000 MT/S CL14, which achieved 41.4 ns. You’ll notice that the higher the DDR5 frequency, the narrower the gap. Note that a 3200 MT/S CL16 DDR4 kit has a latency of 50.3 ns. Here, it’s 54.4 ns and first place for our Patriot Viper Xtreme 5 8200 MT/s CL38 memory kit.

Geekbench 3.4.4:

This benchmark is available in several revisions, version 5 having just been released a few weeks ago. It provides two scores: one single and one multi. Using this benchmark, we’re going to focus on performance obtained on the ” Memory Multi-Core ” score, which differentiates memory performance.

The version used for testing is 3.4.4.

For the Geekbench 3 benchmark, despite the single-core frequency of our i9-13900KS being 6 GHz, there’s a difference in score between the different memory kits. Our sample of the day takes third place, even though the difference is almost non-existent.

In multicore, we move up one place to find ourselves behind the Teamgroup kit, but with a higher frequency of 8400 MT/s.

As soon as we isolate the memory score, real differences are visible between the kits. Our kit of the day scores 14,250 points! We’ll be keeping a close eye on this score when we start overclocking. It’s a good indicator of the benefits of overclocking.

In DDR4, our best kit scored just 7,748 points. Once again, DDR5 combined with the Raptor Lake processor offers a huge advantage.

Geekbench 5.5.1:

We’ve decided to add this extra benchmark, but why? The CPU benchmark uses new tests that more closely simulate the tasks facing processors in the face of recent applications. Geekbench 5 also increases the memory used in the benchmark to better reflect the impact of this parameter on CPU results. For the time being, we’ll be keeping both, as version 3 is still widely used. We have also migrated to the latest version, 5.5.1.

Whereas in Geekbench 3, we had a difference in single core, here in version 5, the gaps are smaller but, as in the previous version, we find a slight delay in our Patriot kit.

Finally, the score for our Patriot Viper Xtreme 5 kit at 8200 MT/s CL38 is 28,581 points. Still to give you a reference score in DDR4, our best score in Geekbench 5 was 11,179 points.

Geekbench 6:

We recently received a key for Geekbench version 6. We therefore took advantage of the change of configuration to add this new benchmark to our test suite. This is the latest benchmark and is intended to be more representative of current configurations. Primate Labs also assures us that the scores displayed by Geekbench 6 are more accurate in relation to the various existing devices and platforms. In fact, the test is much longer than the other two versions we use. Our tests will be carried out on the latest version, i.e. 6.2.2.

The scores in the single test are fairly close, which explains the slight but ultimately insignificant change in the leading order. Our sample of the day once again stands out from the crowd.

Let’s end this series of benchmarks with the multi part of Geekbench 6, where we end with the performance configuration encountered during all our tests. There’s no doubt that this is one of the best-performing kits we’ve had our hands on, clocked at 8200 MT/s.

[nextpage title=”Overclocking on our APEX Z790:”]

Choosing your DDR5 kit based on memory chips:

As was already the case for DDR4, if you want to clock your memory, certain brands will benefit from better potential. At present, the kits announced by the various brands benefit from either Micron, Hynix or Samsung chips. The latter two brands will be the most interesting. As you can see, our Patriot Viper Xtreme 5 kit, clocked at 8200 MT/s CL38, is equipped with Hynix chips. Unlike our last kits, these are not Hynix A-die chips, but the new Hynix M-die chips. These have the particularity of rising more easily in frequency, but being more complicated to tighten in terms of timing.

To take advantage of high-frequency kits, it’s best to be equipped with a motherboard dedicated to this type of kit, and in this game, the ROG APEX Z790 is certainly the best. It features two memory slots to facilitate memory overclocking. You’ll also need a processor with an excellent IMC (Integred Memory Controller). Beware: a processor may have excellent overclocking potential but, on the other hand, a disappointing IMC. These two factors are independent of each other.

Key DDR5 voltages :

For memory overclocking, there are 5 key voltages. These are the voltages that will have an impact on overclocking and therefore on frequency rise or timing tightness. These are the CPU System Agent Voltage (SA), the DRAM VVD Voltage, the DRAM VVDQ Voltage, the Memory Controller Voltage and the IVR Transmitter VVDQ Voltage. Here’s where you’ll find these voltages in the BIOS of our ROG Maximus Z690/Z790 APEX.

Please note that, depending on the type of memory chip (Micron, Hynix and Samsung), the balance between these different voltages is different. If your PMIC module is not locked, by activating ” High DRAM Voltage Mode “, you’ll have access to voltages up to 2.00 volts. Now it’s time to overclock this Patriot DDR5.

Step 1: use available BIOS profiles

It’s a strange thing to say, but a few months ago, we were happy to have the BIOS profiles available as a good basis for our work. However, since the arrival of the Hynix A-die and now the new Hynix M-die chips, the frequency of kits has exploded, and in the end, the profiles in the BIOS are lower than the current frequency of our kit. There’s a 7600 MT/s CL36 profile and an 8800 MT/s profile for Hynix A-die chips, so we’ll have to build our own profiles.

Step 2: 8800 MT/s CL38 target

This is our first objective, to reach the 8800 MT/s CL38 frequency, as this type of chip should be able to do this quite easily. We set up the BIOS, modify voltages, timings and subtimings, and off we go.

The good news is that it starts without a hitch, and our two benchmarks go straight through. We’ve run several in a row, and there’s no worry about stability. Finally, I thought the IMC of my i9-13900KS was limited to 8700 MT/s, but that’s not the case. In fact, this is the first time I’ve reached 8800 MT/s. As you’d expect, throughput in AIDA64 is through the roof, with read speeds of 136,620 MB/s and a Geekbench3 memory score of 16,307 points.

Step 3: creating new profiles

At the start of 2024, we’d like to develop our overclocking tests for DDR5 memory kits, whether Hynix A-die or Hynix M-die. We’re busy preparing test profiles that will enable us to evaluate the overclocking capabilities of the kits by checking their stability. As January is a busy month for hardware launches, we’ll be starting these new tests in February.

[nextpage title=”The last word:”]

What a pleasure it is to have the Patriot brand back on test on our site. The brand has a very interesting catalog of memory kits, and we hope to be able to offer you further tests in the coming weeks. This Patriot kit from the “Viper Xtreme 5” series, clocked at 8200 MT/s, is the brand’s fastest, and delivered excellent performance in all our tests. Although an RGB version is available, our opinion is that these black and red modules are much prettier.

Overclocking is no exception, as our tester easily managed to reach the 8800 MT/s CL38 frequency. After this month of January dedicated to the launch of NVIDIA and AMD graphics cards, we’ll be coming back to the overclocking of this one, with the aim of reaching 9000 MT/s.

Priced at $239.99 on the brand’s U.S. online store, it could also prove very interesting financially after conversion into euros. Following this article, we’ll be contacting the brand to find out where to purchase this kit in Europe, as the brand has a European presence.

Patriot Viper Xtreme 5 8200 MT/s CL38 :

We liked :

  • A kit for overclockers!
  • The original 8200 MT/s XMP, ready for high-end configurations
  • The sober design of the memory modules and their atypical design
  • High-quality finish of memory modules
  • The best-performing Hynix M-die DDR5 kit we’ve ever had!
  • Excellent overclocking potential combined with the Z790 APEX and a CPU with a good IMC
  • Lifetime warranty
  • 240 price tag, which should be very attractive when converted to euros

We would have liked :

  • A way to find it more easily in Europe

This is my first test of a Patriot memory kit featuring the new Hynix M-die chips, and to say the least, it packs a punch. The 8200 MT/s XMP profile proves ultra-high-performance, and the overclocking potential is also incredible, but only with a top-of-the-range motherboard and a processor with a very good IMC.

Once again, thanks to Patriot and especially to Shannon Robb for this Viper Xtreme 5 8200 MT/s CL38 kit. I look forward to reviewing another Patriot kit.
