Corsair have just sent me notice that another RAM kit is being delivered to me. I do not know which version of kit it is. I assume it is another Corsair Vengeance RGB Pro 3200MHz 4x16GB kit as I have no responses to the technical information and questions I requested w.r.t the differences between their Corsair Vengeance RGB Pro 3200MHz 4x16GB kit (which makes no claim to support AMD 400 series motherboards on the web page) and their Corsair Vengeance RGB Pro 2666MHz 4x16GB kit (which does claim to support AMD 400 series motherboards on the web page).
I will ask again for answers regarding the result of Corsair failure analysis on:
1. The original Corsair Vengeance RGB 3200MHz 4x16GB kit I purchased based on Corsair Memory Selector, where 1 16GB stick fails to pass Memtest86 run at default SPD speed (2133MHz) SPD timing (15-15-15-36 ) and voltage (1.2 Volts) specification.
2. The RMA Corsair Vengeance RGB Pro 3200MHz 4x16GB kit where 3 16GB sticks fails to pass Memtest86 run at default SPD speed (2133MHz) SPD timing (15-15-15-36 ) and voltage (1.2 Volts) specification.
I will update this page with more information when and if I get more answers from Corsair w.r.t which Memory Kit they will be sending me as RMA replacement number 2.
colesdav, I am curious where we find these 400 series MBs? Thanks and enjoy, John.
I do not know which motherboards Corsair tested exactly.
I guess I should have written AMD 400 series chipset motherboards such as Socket AM4 X470 / B450 motherboards.
RE: I will update this page with more information when and if I get more answers from Corsair w.r.t which Memory Kit they will be sending me as RMA replacement number 2.
RMA Replacement kit 2 is another Corsair Vengeance RGB Pro 3200MHz 4x16GB kit.
It arrived 15 hours ago. I immediately installed all 4 sticks. I have been running the first Memtest 86 for the past 13 hours and 40 minutes at at default SPD speed (2133MHz) SPD timing (15-15-15-36 ) and voltage (1.2 Volts) specification.
I will update the Memtest 86 information and testing results summary as soon as I can.

colesdav, good results? How does it do at 3200 MHz? Thanks and enjoy, John.
I have been able to pass 2 separate Memtest86 tests at 2133 MHz and 3000 MHz with all four sticks in place.
That is much better than I have been able to manage with either of the previous two RAM kits.
I have been able to get the PC to boot and run at 3150 MHz. I am running Memtest86 at that speed with all four sticks in place.
The PC will not boot at 3200 MHz, which is only 50 MHz below the tested speed of the RAM.
There was no point in looking to gain an extra 50MHz if the test at 3150 MHz fails.
I might have to adjust RAM timings a little or modify voltage in BIOS but before I spend any more time on this I just want to see if it can pass or fail at 3150MHz.
I need to do more testing before I can give a definitive answer on this RAM kit I have. I need to run the tests at different CPU load conditions.
Each Memtest86 run is taking 14.5 hours with a full 64GB kit so it will be days before I am confident that there are no issues.
I am still waiting for Corsair response to a number of technical questions I have.
I have asked them to run failure analysis on the previous two kits that had to be returned.
ASUS have offered to request QVL testing for the same setup.
Memtest86 test at passed at 3150 MHz with with all four 16GB sticks of Corsair Vengeance RGB Pro 3200MHz 4x16GB kit installed on the motherboard.
I tried further testing on the motherboard BIOS settings in an attempt to push the DRAM frequency to 3200MHz and see if i can pass Memtest86 as follows.
(A). Just increasing DDR4 frequency to 3200MHz in BIOS saving to a new profile, loading from that profile and attempt to reboot into the PC fails.
The memory frequency settings get reset to default due to failure to boot.
(B). If I increase VDDSOC
I increased VDDSOC by 0.1 volt as advised by misterj (thanks) and based on other discussions on overclocking forums.
Doing that allows the PC to boot up with DDR4 frequency set to 3200MHz.
However when I run Memtest86 at this speed it fails early on in the test.
I have stopped testing at this point for today as i am kicking off some more Memtest86 runs at 3150 MHz with different BIOS settings for DIGI+ Power Control.
I will be making my BIOS settings available to both Corsair and ASUS via support case once I am happy with the settings I have.
WoW, what a wrestle to get Corsair running and it's not even 3200?!
Kingston Predator ram is running 3200 (1600Mhz) here just fine on my 2700x
