In this thread I will present the latest version of HyperX Predator memory. It's also the highest frequency memory kit released so far - DDR4-3333.
As all HyperX Predator series, also here we can find Hynix IC. Below is screenshot from AIDA64 with info about what is under the heatsinks. I can't or maybe don't want to remove heatsinks as I have to return this memory after tests.

As you can see, kit contains two 8GB modules. Both are single rank and SPD profile is DDR4-2400 at CL17.

My test kit has two XMP profiles but so far I wasn't able to run DDR4-3333 profile. What more I couldn't make this memory work above DDR4-3200.
Here is XMP#2:

3333 is stable on new BIOS releases. 5h+ in AIDA64 below:

3200 15-16-16 1.35V 2T

3200 14-16-16 1.40V 1T

For some reason AIDA64 in SPD/XMP tab is always showing +0.02V memory voltage even though in sensor tab it's the same as in BIOS.

I found out that this memory requires new BIOS version which is not really available for some motherboards. On ASRock Z170 OCF and MSI Z170I Gaming Pro AC [email protected] is not working and on both I can't make this memory work above ~3200. On MSI it's not working even lower. However [email protected] is working fine on ASRock X99M Killer 3.1 motherboard which supposed to be much harder to overclock than Z170. I was able to run it at ~3400 on X99.

Hi Woomack! Thank you for your efforts on reviewing memory modules! Why don't you use Thaiphoon Burner software for taking screenshots with SPD info? This app displays much more useful information comparing to AIDA64. Besides, URLs to all reviews where Thaiphoon Burner has been used are added to the database of the program. This helps users to find reviews on required memory modules.

I'm actually using Thaiphoon Burner but not in all reviews. Missed it in last 2 as I see. Here you have SPD tabs ( all from this year ):

I didn't know you are adding reviews to your database.
SPD window is good but in other one with report there is always Hynix IC as manufacturer, regardless if it's Hynix, Micron, Samsung or anything else. I mean in SPD can be Samsung while in report is Hynix or nothing + Hynix. I also don't know if thermal sensor data is correct. Every soft is showing something else.

Back to this review, I just started it and can add TB screenshot but I had some issues with compatibility so I wait for new BIOS from ASRock ... or I will get different motherboard. I will add some more results soon.

Max stable OC is 3466 while max benchable is 3600. Both at CL16-18-18. For some reason higher voltage is not helping much in stabilizing memory.

The most important update is that if you have any issues with stability using this memory then update BIOS/UEFI or if there isn't any newer then ask your motherboard manufacturer to take a look at compatibility with new Kingston memory kits. At the end I've received beta BIOS for MSI Z170I Gaming Pro AC on which this memory is working great.
I added stability test at 3333 to the first post.

I noticed the same with that Corsair platinum Gigabyte Ed. I got recently Woomack. Actually anything over 1.5v and it won't boot. In windows if I set voltage higher in software instantly freezes. I know it's Hynix but I think a bit older. I thought they would have fixed that by now.
I have this stuff running 14-15-16 1.5v @ 3400
Thought I had some test pics on this stick but no. Here's one I subbed recently

Your kit is based on lower capacity IC. These kits were sometimes scalling better and sometimes worse. Usually Hynix kits couldn't pass 3333-3400 and were scalling up to 1.5V. Samsung can make some more but at more relaxed timings. You are somewhere where I was with couple of other 4x4GB kits. Still not that bad as some can't make much more than 3200 at this voltage.

Yeah it's early Hynix MFR IIRC, I just found it odd how it totally shuts down at 1.55v+. It's like the juice just scrambles the signal

Since some point they have problems with signal at too high voltage. I guess that for benching you can make something like:
3000 1.7-1.75V
3200 1.65V
3333 1.60V
3400 1.55V
where most these kits could make something like:
3000 1.65-1.70V
3200 1.45-1.55V
3333 1.35-1.45V
3400 1.35V and relaxed timings <- in best case as most couldn't even boot at this frequency

Considering that, reviewed HyperX 3333 is overclocking pretty good as I could without issues boot at 3600 while on older IC it was hard to do. Good AFR kits can make some more but all depends from luck. There is a chance to lower CL at higher voltage but it's not helping much in general performance and timings would be like 15-18-18 at which it's also not fully stable once I set 3600.

Hi
Wich BIOS Version do you have in the AsRock OC Formula? To update it and finally have this kit working at 3333MHz+

Regards

Right now I have 7.00 BIOS which was released about a week ago. However I had to return HyperX 3333 kit before it was released so there will be no more tests.
In similar way is acting Team Group Vulcan T-Force memory based on the same IC ( but overclocks worse than HyperX ). Team Group was tested with new OCF BIOS and could make up to 3600 ( vs 3200 max on older BIOS ).
There is 3466 result in post #5. On Team Group max stable is ~3333 at about the same timings so I guess it's not motherboard issue anymore but general behaviour of this IC. Software is reading Hynix MFR IC so has to be newer batch as older couldn't make much more than ~3200-3333 stable.

Can you please post all the timings you use with 3466 overclock, mine kit fails the memtest for some reason

I don't own this memory anymore. As you can see, this thread has three years.
