1.482V under load as seen in HardwareInfo64 for 3600MHz.
I lowered clocks a bit for even lower voltages and this is the result 3535MHz with lil better timings and 1.465V.
What do you think, what profile is better, 3600 or 3535?

Shouldn't Tcl and Tcwl be the same? And at lower speeds like 3535 you might be able to do 14-14-14-14. At least that has been my experience. Once I get to 3600 I have to use 14-15-14-14.

So the 1493 cinebench screen and aida is the one at 3600?

I would prefer the sub 60ns result setting, since mine is used especially for gaming I would tend on low latency settings instead of high bandwidth

I would like to see the lowest timings possible at which frequency levels and decide which more effective route follow

2666 cl12

Or 3466 cl14

I want to stay at 1,4v max at dimms

Ok thanks for clarifying

I’m near that setup but with 1,4v and 3400

I will try 3466 and see if it is stable

Then i will try the lowest timings possible on ddr4 and decide where to go

Anyway my 2600x could not manage 4,[email protected],4v all cores so I don’t know if overclocking it the old way will bring much to the table instead of leaving on pbo and xfr


Both CB Scores are with 3600, but cpu clock is lower in one of the pics.

Now this is what i am trying for now with 1.465V RAM Voltage:

I was told, that Samsung B Dies are laughing about 1.5V, the guy told be 1.5V is no problem at all for Samsung B Dies 24/7.
But if they get over 55°C, they get instable, he said, so lower voltages are ofc better, but how much will you sacrifice?^^
I think our RAM is nearly perfect tuned, i have now 3 Profiles, 3466/3533/3600, dont think, that any of these profiles are a lot better than the other one.
I am looking forward for Zen 2, my 2600 will go to my second PC, i hope we can push RAM even further with Zen 2.
Anyway, thx for your input.

HWinfo is not an exact "device" for measurements, you should focus only on those values that you entered in the BIOS

I keep worndering how people getting over such high ram temps? I have been running these B-die G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 4133MHz (PC4 33000) Desktop Memory Model F4-4133C19D-16GTZR https://www.amazon.com/gp/product/B01NCV4CY8/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

at 1.48 volts almost from day one with no temp issues. It rarely ever even hits 35 celsius at 3600+ at CL 14 and very tight timings. Ambient though is 26 -27 celsius.

Mine only get into the 40s when I am testing them. Gaming can reach 38, but that was during the summer when my room temp was pretty warm.

26c ambient and 35 at 1,48? Well you have to cool them with something then, i get even 42 at 1,4 3400 cl14 and I have a decent airflow

Ps: during testing too

Alright, one more time around with Ryzen + and Memory clocking. 2700x, TWO 16gb 3600mhz B-Die kits..... Lets do this. One was free too. I LOVE Amazon. Hehe.

Best one stays.

MY Halloween is going to be the best! Have fun you guys!

Doesn't increasing memory voltage also indirectly pump it to your CPU since Ryzen integrates a lot of things on the chip itself that the motherboard normally handled on Intel platforms? That's why 1.45-1.5v has been the 'max' that's been recommended. Correct me if I'm wrong please.

The OC guides I've read by Elmor on Intel/Ryzen always have:-

"Depends on your DRAM sticks, the limit is considered from CPU IMC side."

Dunno about temperature effect from this, but some CPU IMC's may not like increased VDIMM IMO. JEDEC allows XMP certification of upto 1.5V on DDR4. The other consideration of increased voltages is perhaps things like noise, etc. I do tend to go as low as I can for a setup, may that be VCORE/SOC/VDIMM.

24/7 settings for core and mem 3700c14

PE Level 2
Core Ratio Auto
Vcore Offset -0.10625
SOC 1.1
Vdimm 1.425
LLC 2
WOW :specool: .

3700 CL14 24/7 stable, that would be impressive. Don't forget to endurance test yours. This setting is gamestable, but it doesn't like the tfaw setting at 3600. I'm wondering how you can even boot at 1.425 V. I need 1.45 V to archieve 3600. Up to 3866 is bootable but of course very unstable and only CR2. If I get 3600 working with decent timings I'm already happy. Most people suffer when trying to reach 3200-3400.

was about time lol

32GB Kit (G.Skill F4-3600C17-16GTZR)

3466/LL almost 15hrs run for %1300+ coverage on a B350-I Strix mobo

SOC 1.00v
Hello, can you provide all timmings and other config to achieve this result? I have same memory but I'm not getting stability in 3200 mhz :(
