Avexir DDR4 Blitz Series Review


It’s a perfect time to customize your PC and personalize it to color coordinate your system. Memory manufacturers are now adding memory with LED lighting and hopefully moving towards RGB in the possible future. Avexir is a company getting popular in the US for having an answer to the lighting and RGB craze, and even has its own unique share of this market. Avexir offers innovation technology like its plasma tube ram, and blitz series lighting. Avexir’s motto is “What we believe is how we behave”. The companies entire vision is to provide the best memory modules to every gamer and be the leading manufacturer in the RAM market. Today I will be looking at Avexir’s Blitz series of DDR4 RAM so we can see what these modules have to offer and what makes them so desired for system builders.


The RAM kit that was specifically sent to me was the Blitz White. There are dual channel and quad channel kits available on their site. The kit I’m working with is QUAD channel and the model is AVD4UZ130001604G-4BZ1SW. This kit is 4GB x 4 giving a total of 16GB of ram.

The shipping box has the company’s motto and feels heavier than normal for RAM.  Unboxing the unit the product packaging offers a quick glimpse of what the Blitz series is about. We see three distinct colors of red, yellow, and white. The bottom says ” Blitz Series customized to perfection”.  Holding the box in my hands feels good because it’s heavy and, I get the feeling of quality from the weight of the box.

The site actually lists the Blitz series having ” six LED colors of Blue, Red, Yellow, Green, White, and Orange, so you always have the right choice to suit your motherboard”. Under the DDR4 page, neither of those colors are listed in the product specification section or shown in the pictures, so it’s possible those colors will be a future release. The box doesn’t show off these colors, and the DDR4 page shows that quote under “Various Choices of LED Colors”.

The back of the packaging offers a brief overview of why the Blitz series is important to overclockers and gamers. The English is a bit broken, but basically, it says It’s a successor from Blitz 1 and offers removable heat spreaders for overclockers in favor of liquid nitrogen. It also states it suitable for all motherboard manufacturers and has strict visual standards for its LED’s.

Each module is packaged very neatly and also offers a guard for each modules pins. This is a nice feature that all memory manufacturers should follow. It doesn’t cost much and makes the consumer feel like care is taken in each box. The guards help protect the pins and avoid air and water oxidation during shipping.

The Avexir SW series is classically composed of silver and white and is listed as a limited custom model. The new Blitz series was designed with overclocking and gaming in mind and offers removable heat spreaders. The claim is this is useful for extreme overclockers who want to use liquid nitrogen for ultimate results. The other great part of the Blitz series is its combination of quality lighting and selection of the RAM IC.

Avexir’s use of removable heat spreaders is really cool. You can pretty much do this with any RAM module, but Avexir supports it. They use this to their advantage in the Blitz series and also offer thermal pads. These pads are used not only for heat transfer and better performance, but to allow easy removal of the heat spreader itself. This will allow you to leave the memory unharmed.

snap10282016103037AM.pngAvexir is really picky about what IC modules they use for their products, which in return give the end user much more reliable and better-performing RAM. They call this process AIST. Avexir states, ” Every set of memory modules from AVEXIR are all carefully picked by AIST (AVEXIR IC Sorting Technology) and have to pass hundreds of motherboard compatibility test and eight hours of reliability test during lab test with Design of Experiment method (DoE) to ensure the whole system is rock solid stable and the RAM is sufficient to run constantly.” I pulled the above report from Thaiphoon Burner. This tells me the IC modules used are from Samsung and are labeled as K4A4G085WE-BCPB. Samsung IC is also used in Avexir’s premium line of Plasma ram. I want to quickly point out the XMP certified profile is for 3000 MHz (1502*2), but isn’t picked up as that under the XMP profile in my bios. I had to manually set 3000 and set my timings. I will be explaining this better and be showing this off later under testing.

I am going to be keeping things relatively simple when it comes to ram testing. My primary benchmark will consist of testing with AIDA64 Extreme. AIDA64 does a great job at testing memory bandwidth to its full potential. I will also use Prime 95 blend test and RealBench to stress test the RAM. I will also use RealBench to benchmark the RAM as well. I will compare the PNY DDR4 2800 MHz memory kit vs the Avexir DDR4 3000MHz just so you can see how much faster 3000 MHz is compared to 2800 MHz. This should allow you to make an educated choice for system memory when purchasing based on performance and price.

My test bench is as follows:

  • ViewSonic XG2703-GS Monitor
  • Motherboard- EVGA Z170 Classified K
  • CPU: Intel Core I7 6700K
  • Network Card- Netgear AC 1200 USB
  • Cooler- Thermaltake 3.0 Water Extreme S with TT Premium Riing RGB Fans
  • Memory- Avexiir DDR4 3000 MHz
  • Video Card: Nvidia GTX 1060
  • Storage- PNY CS2210 480GB (Boot) / Toshiba VX500 512GB (Boot) / Seagate 3TB/ Zotac Sonix 480GB (Not used for tests) / Toshiba RD400
  • Power Supply- Corsair RM650X / Sleeved CableMod red/black cables
  • OS: Windows 10 x64 Pro
  • Headphones- Creative H7


Testing memory isn’t always perfect due to overclocking, XMP profiles, and comparisons. You need to have similar modules to see any major differences. Memory rated at the same speeds (MHz) could be using different ICs (Integrated Controllers) which is what the chips are soldered to your memory. It’s best, in my opinion, to test individual memory against other brands at the same frequency to see any real world performance. Most of the time, though, you are going to be close depending on brand and parts used. What’s important for memory is making sure it does what you need it to. Can it run at its rated XMP profile with your overclock ? Can it run at your target speed with tighter timings ? Make sure when you buy memory it will reach your expectations.

The best thing to do when overclocking is to just set XMP in the bios and focus on what CPU overclock you can get with the XMP profile, this is the easiest thing to do. If your overclock isn’t working correctly with XMP or causing stability issues, you may have to step back your memory frequency to achieve your CPU overclock, or back the CPU overclock down. Setting the XMP profile for the Avexir ram was problematic. I did not get the advertised speeds from the XMP profile. You can see this in the above picture!

I also notice my EVGA bios sets healthy voltage for the DIMM Voltage on auto. Generally,  I just leave that alone as the bios will supply enough voltage to keep the memory stable in case it needs a bit more than what the kit lists. My Avexir RAM is rated for 1.35V (PC-2400) DDR4 3000 MHz at 16-18-18-36-2T. My auto voltage is 1.387 which is a bit high but nothing to worry about. Look below to see what Intel recommends for proper voltage specification for XMP 2.0.

1.2V or lower = Best for DDR4
1.35V = okay voltage for overclocking kits
1.5V =absolute max voltage allowed for Intel XMP 2.0 profiles and max suggested voltage


In my case to reach my desired 3000 MHz speed I had to manually enter the proper specs to reach that frequency. I also had to set voltage higher for two more items in the bios. If you’re having problems with XMP you can try to stabilize it by increasing the voltage for VCCIO (VTT or IM voltage) and VCCSA ( System Agent). The IM ( Integrated Memory) control the voltage for the memory controller of your CPU and the system agent voltage helps stabilize  your BLCK or base clock.

Intel’s safe tentative voltage for each of these are:

  • VCCIO: 1.25v/1.2v
  • System Agent (SA): 1.3v/1.25v

Some will argue lower timings are better than faster speeds, but in reality make sure you focus on your overclock first, and then your memory because a faster CPU overclock will always show more real world benefits over any memory overclock. For instance, the default memory frequency for 1151 Skylake CPUs is 2133. If you can achieve a 4.7 GHz overclock with a 2133 MHz memory speed, it’s best to take the higher overclock as far as performance is concerned. This shouldn’t stop you though from trying to reach your highest memory overclock either. I settled on 4.6 GHz with the 3000 MHz speed the Avexir memory supports. I couldn’t reach 4.7 GHz anyway without going over my voltage comfort limit of 1.35V.

This RAM scored 80692 for  the Realbench system score. I also ran Prime 95 with the blend test to make sure my system was stable with the 3000 MHz speed and my 4.6 GHz overclock. I ran the test for a few hours just to be sure. I wouldn’t generally recommend using Prime 95 as it can be a power monster on your CPU causing temps to go way beyond their limit. I wanted quick results and the blend test isn’t as bad as small ftt. I also ran the RealBench stress test for 4 hours just to be sure.


The ADA64 test shows very minimal differences in speeds going from 2800 MHz to 3000 MHz, but overall the Avexir RAM is faster as expected.  As you can see testing memory comes very close in numbers and what should matter is price and your target overclock goal. The Avexir kit does shine on the write and copy tests, so having faster memory will benefit load times in games and copying multiple files across your system.

You can see in the above video what the lighting is like for this kit. This is what makes Avexir so popular right now due to its interesting LED lighting choices and its plasma kits. The blitz RAM has a flashing light pattern in the color of your purchase choice.



When it comes time to make a purchase decision you should focus on price for DDR 4. If you’re looking for higher rated speeds you have to be careful if you plan on overclocking as it’s not guaranteed to run at that speed with your overclock.

The Avexir DDR4 kit I tested performed extremely well and its best feature is the lighting. This makes Avexir a compelling choice for a  RAM purchase because it gives system builders more character to match their systems color scheme. Avexir’s use of IC sorting is really thoughtful by making sure stability and consistency are part of every package. This should give every confidence in their purchase decision.

I highly recommend this  kit for anyone looking for more than the standard looking RAM for their system. You can buy this Avexir kit right now for $133.00. I am going to apologize because normally I have no problem finding the prices or the product online to link, but when I couldn’t find a USA store link, I reached out to Avexir and they wanted me to use this link here. It will show in Euros for € 119.00.
