I have a question and can't found the anwser online about my memory DDD4 Trident Z Neo.

[Alex Jones]

Hello guys I have a memory kit of 32gb 3600ghz, Trident Z Neo (Hynix) im Running at 4000mhz and tight timings, using 1.70V and had give me a Huge FPS boost, and I can't undervolt or won't boot at this clock, Do you guys Think is Fine running at this voltage, I have a great airflow inside my case and the temperature is fine. Thanks

RAM is fine to OC fairly high while staying safe. The issue is when you set the State of Charge (CPU) voltage past 1.4v - for DRAM, you can even set the timings tighter lowering the CAS.

If i ve found the right kit - it s meant to operate within 1.2-1.35V . Dont think 1.7V is safe . You can keep these settings at your own risk .

Yes, some guys told me the maxium is 1.60 1.65, for extreme overclock.

That is absurdly high. Especially for daily drive. Did you run Linpack with that?

its only overclocking the cpus imc easily with 2 dimms
but with 4 dimms it will be more limited

you can always swap more mhz for timings
but often best at the dimms xmp profile, else they would sell it at a higher freq

So 1.7v is, allot...

To put that into perspective, thats the type of voltage that would have been more common in DDR (1.8-2.1v) or DDR2 (1.5-1.8v) days.

DDR3 is typically 1.3-1.5v, so you are pushing hot to trot. Might want to tune it down to 3600mhz and just work on tighter timings, specially if you are on AM4 where jumping above 3600/3800 (depending on chip) tends to require a divider in play.

These.

The last time I saw anywhere near 1.7V was my DDR2. My DDR3 and DDR4 were/are both 1.35V.

What is the state of charge? Are you referring to the SoC? That's the "system on a chip", and the IMC (the relevant part that communicates with the memory) is part of that.

If so, different CPUs have different tolerances (and on Intel's side I'm finding it's debated what is/isn't safe so I can't speak for that), so no single voltage should be given as safe here.

And it's far from this that matters. RAM voltage definitely matters.

ddr3 is around 1.2-1.65v, 1.5v was normal

1.7v is around the ddr2 era range
way too high for ddr4

the cpus imc has its own voltage controller, dram voltage is only for the dimms
the cpu/board has buffers to keep the voltages separate

I'm using now 3800 mhz, 1.62V.
