HyperX FURY DDR4 2133 Question.

I am at 3200 MHz under 1.28 V as C15 17 17 28 with my (4 x 4GB) Kingston HyperX Fury (C14 2133 MHz), no sweat.

This does not affect the product's lifespan in any way. In fact, how could you prove anything if the chips are not black, melted and smoking? Staying within voltage and temp. tolerances is perfectly safe. It's being done everywhere. Nothing new here...

The Fury operate off PnP so effectively they should clockk up to the highest speed they are rated for that the mobo and CPU allow by default....to run 2666 you'll need a set of 2666 or better. Here, your mobo supports up to 2133 so the 2133 sticks would run at 2133.

Can you post up screenshots of CPU-Z showing the SPD tab and the memory tab - would like to see these 2133 sticks running at 3200 with the timing voltage you mention Not that I don't believe you, but find it on the far fetched side

Sure - seeing is believing, right?. My testing is done on the latest version of Prime95 (latest version) for hours at a time, both "blend" and "heat" tests, all extremely stable results...

These days I use C15 17 17 28 @ 1.34 V, or even 1.36 V (for added stability under all circumstances) on 3200 MHz. The (very thorough) HWDB tests for this exact setting (http://hw-db.com/memory/2687/hyperx-hx421c14fbk2-16-review/2) resulted in 1.35 V being the end result for this setting but somehow my Gigabyte MoBo jumps from 1.34 to 1.36 V (2 at a time). So I settled (for now) on 1.34 V which has always been rock solid. This is an excellent outcome in any case ;-).

Look at my progression up to a score of 767 on Cinebench with my 16 GB (4 x 4 GB) at 3200 MHz under 1.28 V using the timings C15 17 17 28 for my Kingston HyperX Fury (C14 2133 MHz) sticks which come with this mention:

This is copied directly from my invoice and receipt from the store. Seeing how good the result was, I went back for a second 8 GB kit of the same (I insisted for the salesman to pick it up from the same box, lol) and even got a better deal - price reduced by $10 :

Have a look here (your much loved CPU-Z) Memory Tab (there is nothing under my SPD Tab): 15 17 17 28 (vertically) at 3200 MHz (1600.1 MHz for each of the two channels) and with a Command Rate of 1T (even better):

While at it, I also got HWINFO64 for you (showing a clock of 1600.4 MHz on each of the two channels at the bottom right under "Memory"). Please note on the picture: Type: DDR4-2134:

... and here (the more serious Intel XTU) where you can also see that my Command Rate (CR) is 1T even though I have 4 sticks (not 2T) - at the bottom left: 1T 15 17 17 28. And check at the right under "Intel Extreme Memory Profile Custom" in orange -> values vertically just below "Memory Multiplier: 32.00x".

By the way, my MoBo is a budget Gigabyte GA-Z170XP-SLI because I use two heavily overclocked MSI GTX 970 cards in SLI mode - (112 fps + on "Ultra" everywhere) - with my DDR5 memory running at 4000 MHz on each card.

Also have a look at these tests by HWDB, the hardware database, specifically for the Kingston HyperX Fury:

For the primary timings (CAS, tRCD, tRP and tRAS), the minimal stable values depend primarily on the memory frequency with voltage playing a secondary role in the borderline areas. However, on Skylake you also have to keep in mind that tRCD must be equal to tRP at all times and that the minimal tRAS value one can set in the BIOS is 28.

Too easy... Have fun
