Review: AVEXIR Core Series 4x4GB DDR3-2800 MHz CL12
Category : DDR3
Published by Christian Ney on 20.11.12
Today we are - finally - going to review AVEXIR's second most expensive memory kit. The one we used 80 days ago to break the DDR3 frequency world record. Without liquid nitrogen on it this kit is still one of the fastest kits out of the box. That's right, 16GB of memory rated DDR3-2800 MHz CL12 at 1.65v.

AVEXIR is a company that seems to have popped up from nowhere. In fact they were around for some time now as they established in 2006. But they were in the shadow of other big manufacturers. However since the beginning of this year they are really pushing and have now a nice spot in the enthusiast market. Not only because they have some really nice products, AVEXIR also offers these products at competitive prices.
The Core series is AVEXIR's high performance memory line. Looking at the specs and the design we can indeed confirm that. Rated at DDR3-2'800 MHz that's the highest clocked memory out of the box in the market. Timings aren't the tightest that we have seen at these frequencies but they are tight enough to offer best performance.
It's not even the fastest kit of their line-up. AVEXIR also have a DDR3-2800 MHz CL11 kit in their portfolio. Enough talking, let's have a closer look on the following pages.

Closer Look

The AVEXIR Core kit arrives safely boxed in two transparent plastic blisters which are put in a small cardboard box. The box shows us the memory kit in action with the blue LEDs. On the back you have all the features as well as a sticker with the part number and the specs.





The design is clean and kind of futuristic. On the top you have a transparent plastic tube that will be illuminated by the blue LEDs when the system is on. The heatspreader is made of aluminium. It comes with a black painting and it's not too flamboyant. Furthermore it's not oversized, only 6 mm over the standard 3cm height.
On one side of the modules you can find a sticker where there is the part number with some specs.
LEDs colour cannot be changed.





With heatspreaders out of the way we see that AVEXIR chose to make use of Hynix's CFR PBC memory chips.




The SPD reading tells us more about the memory itself like the capacity, the name of the manufacturer and the JEDEC profiles stored which are in 6 accompanied with one XMP profile. Furthermore Avexir did something really nice when it comes to the part number. In fact they just redefined the term "awesomness". Instead of entering some weird numbers they've put in my name! How cool is that
The SPD has been well recognized by the BIOS of our motherboard but not by CPU-Z. The XMP is 1'400 MHz 12-14-14-35 and CPU-Z reads 12-15-15-36.

Testing Method & Test Setup

Knowing about Hynix CFR's capabilities from recent reviews, we armed ourselves with an Ivy Bridge testing platform that should allow our memory to show every last bit of its overclocking potential.
To make sure that our figures represent the sort of stability safe to use ever day, we are going to run each setting until we get a 150% pass of eight 750MB instances of HCI Memtest that is considered one of the toughest memory stress-tests around.

Motherboard ASUS Maximus V Gene (BIOS 1204)
CPU Intel Core i7-3770K @ 4.0 GHz
Graphic card ASUS GTX 580
Memory AVEXIR Core Series AVD3U28001204G-4CI
HDD Intel SSD 330 120 GB
PSU Seasonic Platinum 1000 Watts
OS Windows 7, 64 bit SP1


Results


Our processor's IMC isn't HCI Memtest stable above 1'330 MHz (DDR3-2660) on the memory. Therefore we stopped the testing at 1'330 MHz.




As you can see the kit has some issues with voltages above 1.65v. We reckon - based on our experience with memory modules - that limited voltage scaling is caused by an imperfect PCB design.
If you take a look at the other kits we tested, which are also based on CFR chips, then you can see that the ones used here are way above average. There is some serious binning going on behind the curtain.
Unfortunately due to processor limitation we couldn't show the real potential of this kit. With a better IMC, this memory kit would fly at CL11 and CL12. Below we attached a screenshot, showing the memory frequency world record we set 80 days ago with this memory kit and some cold on both processor and memory.

Conclusion

Using geizhals as our price research tool, we find that offers for 4x4GB sets of 2800C12 Core Series start at 233 Euros excluding shipping across the EU. Finding another kit, which shares the same specs, turns out to be quite difficult. In fact, there is only one kit, the Dominator Platinum from Corsair. If you then compare prices you're going to see that Corsair sells their kit for twice as much, 465 Euros.

Therefore AVEXIR's memory kit is very cheap compared to competing products. Heatspreaders are simple but with LEDs, manufacturing quality is good and the ICs used are super high binned. The only real contra that we found is regarding the scaling that stops at 1.65v.
Well done AVEXIR, you have by far the best performance/price ratio.

Pro:

  • Design
  • Wolrd Record memory
  • IC quality
  • LEDs
  • Height (3.6cm)
  • Price


  • Con:
  • Voltage scaling


  • Rating

    The AVEXIR Core Series AVD3U28001204G-4CI kit receives the rating of 5 out of five stars.
