FEATURED Kingston HyperX Fury 2x8GB DDR4-2666 CL16 - HX426C16FB2K2/16

Couple of days ago Kingston released Fury 2666 memory kits. Before higher capacities were available up to 2400. Some users could say what can be interesting in lower frequency memory kits. This memory has one quite unique feature and I'm not sure why other memory manufacturers are not following Kingston. I mean that Fury series has SPD profile = XMP. There is no 2133/2400 setting. Memory runs at 2666 at default on every motherboard which supports higher frequency, even if there is no memory frequency option in BIOS. The same we can see in Impact memory series for laptops. Most laptops don't have memory frequency adjustment options but still if CPU and chipset let for higher frequency then Impact memory runs higher than standard Jedec 2133/2400 settings.

HyperX Fury has low ( or maybe I should say standard ) profile heatsinks which are asymmetric. It looks pretty good on probably all motherboards and there are no issues with any CPU cooling solutions.












We could expect to see Hynix IC under the heatsinks but there are Microns. Below is screenshot from Thaiphoon Burner software which is showing more details about used memory chips.



XMP profile works without issues on Maximus IX APEX. However SPD/auto settings are the same so it doesn't really matter if we enable XMP or not.

2666 16-18-18 1.20V - SPD/XMP


2666 14-14-14 1.35V


2800 15-15-15 1.35V


That's about all. I couldn't make it work at DDR4-3000 regardless of settings. This is actually weird as I was able to set 2800 15-15-15 and it was stable at 1.35V.

Same modules, same processor 7700k, only motherboard is diferent, Maximus Hero IX, but the 2800 settings dont running for me. I have tested changing some point but no result.

Tested:
2800 15-15-15--1.35/6+- boot but fail in test
2800 15-16-16--1.35/6+- freezes in desktop

Depends on luck it may work or not. Micron IC is sometimes acting weird. I would check 16-16-16 or 16-15-15 at 2800 or go for 3000 16-16-16/16-17-17 1.35V.

Only testing with these 3 valors? no need to change more timinigs or other values?

No need at this frequency. Motherboard can set everything else.

With 3000 Mhz hangs or freeze in bios inclusive, in 16 or 17 CL. With 2800Mhz posible estable at 16-16-16, but need to pass more stabilility test. For the moment 2800 - 16-16-16 is the best option.

Thanks.

Is curious, 2800 16-16-16 or 16-17-17 is stable in stress test of memory and use of desktop, but playing games is causing a crashes....

2800 any stable result, playing with CL and voltajes, but is the same, boot, stress test 1 hour +- ok, desktop ok, but the games or heavy apps crashes. And only the game or the app, windows not crashing. 3000 imposible enter in bios, but pass the post.

Is strange, the modules are exact.

What are you testing with ?

My config is in later post. I am using a Asus maximus hero IX, i7 7700k, and the same modules of this post. Is very very similar to testing equip on the first post, only diferent the motherboard.

I presume this modules are very standard,not for OC extremes o very upped, ok, and the diference of 2666Mhz and 2800Mhz is... But the tolerance is near, only perfect with 2666 manual or xmp profile.

Thanks advance.

(Sorry for me english)

Imposible to find values with a free error OC, only 2700Mhz.... very ridiculous.

All 2800Mhz configs make error in Memtest (usually in test 9), and in 3000Mhz i cant boot, hangs, inclusive in bios.

This memory is very poor, or closed to oficial speeds, no OC realiable.
