I have a really weird issue trying to overclock my ram. I have 3200cl14 Samsung b-die Team Dark pro ram (Single rank 2x8gb) both in the 2/4 slots of my Asus Prime x470-Pro motherboard. Paired with a 2700x.

I can easily get the extreme timings at 3200mhz cl14 stable with a 10 hours memory test, but as soon as I raise the frequency to a mere 3246mhz I'll get an error within 30 minutes to an hour. Even with timings looser than the safe presets. My DRAM is at 1.4v and SOC at 1.075 (the most stable settings I got so far).

Any idea what the hell is going on?

hello, im new to overclocking.

i need your suggestion to get stability on overclocking

My Ram : f4-3866c18d-gtzr
ryzen 2700x
ASUS ROG Strix -F x470

Soc : 1.13125
V : 1.45

Its my first time overclocking and im confused what i need to change, i think im close

Is there a way of finding out if my G.Skill RipJaws V F4-3200C15D-16GVR is using Samsung B-Dies without taking it out of the Box? I also could not find any info if this is single or dualrank ram.

Somehow managed to get 3533Mhz C14 with HCI 400%
V : 1.495
I'm running 3600C13\3533C14\3533C13 for 6 months at 1.5v, no problems at all. XMP's max is 1.5v, anything over is not known if safe. I believe that there's a bit more safety room over 1.5 volts

I take my hat off to you! :thumb: . Damn nice results for sure :thumb: .

I had an ~2 day fight on 3466MHz The Stilt preset using a R7 2700X and F4-3200C14D-16GTZ. In a way worth it, as allowed me to gain experience and tune setup before moving on.

I found upto 3400MHz I needed to adjust only SOC/VDIMM. There were 2 settings that created large gains in stability for me on 3466MHz.

3466MHz using HCI passed ~40min, failed Y-Cruncher in <30min. Setting VTTDDR to 0.687V made Y-Cruncher last for ~2.75hrs before fail. Then I used P95, as needed something that made profile fail quick to tune it. Even then it took a lot of attempts to discover ProcODT needed to be set to 48 Ohms. This surprised me, as the RAM I used, has been used with 5 differing Ryzen gen 1 and 1x TR, never did I use that ProcODT value. So as advised by several experienced members in C6H thread at launch, ProcODT definitely needs tuning based on combined HW in use. I also found with CPU stock I needed SOC: 0.956V but when combined with ACB OC of 4.075GHz SOC needed bump to 0.968V.

Anyhow here is some screenies.

ASUS ROG C7H UEFI 0601
R7 2700X UA 1805SUS (PState 0 4.075GHz VID: 1.287 SOC: 0.968V)
F4-3200C14D-16GTZ (3466MHz C15 1T VDIMM: 1.37V VTT: 0.687V)

Idk man, i feel you.. i think every reboot the system with ryzen have a mind on his own. To me it needs HCI stable, As if it dont pass HCI im not comfortable with it. GSAT proves stable but the system with fail stronger tests including whea errors. Same on intel. HCI stable no whea errors aka borderline "semi" stable i will call it.

Sry to just burst in and yell stuff around and btw hi @all, but did you check your DIMM Temperature while stressing with GSAT and HCI? Have a new Ryzen system too since last week with F4-3200C14D-32GTZR as a 2x16GB Kit and tried to oc them too slightly from 3200 to 3333 with optimized timings, funny was that with the same test as you did just only 1hr of GSAT everything was fine and stable but e.g. playing WoW or Destiny 2 gave me random crashes and read errors and i checked again GSAT alone 1hr no problem then i added Heaven in the background and as soon my Stick reached about 50-51 °C errors appeared everywhere, right now i was sitting at about 1.39v for the VDIMMS and about 1.05 SOC but can't test further now my power supply magic smoked yesterday while playing but that's different story.

And great job so far, keep it up :thumb:
thanks.
ram temps around 40s-45s my soc is ((1.00 LLC5 which is even)) i notice i get no stability problems on this once i find one that dont freeze the pc.

But at this point i think im leaving it a 3466 and the timings i have and calling it a day. I dont see no point trying to squeeze that bit extra IN R/W/C

I've contacted Gigabyte support, but they saying they haven't detected any issues while testing exactly same setup and sent me the pictures of them running it at 3200Mhz etc.

If I set XMP Profile 1, I get B2 error and my PC doesn't boot at all, can't get to bios or anything. So I have reset CMOS to be able to boot again. I've tried various stuff, but best result for me is if I select XMP profile 1, but then I reduce multiplier a bit, that way max. I was able to get is 3066Mhz that i'm running it at atm. Could anyone help me get this ram to at least 3200Mhz?

- Corsair CMK32GX4M2B3200C16 v4.31

Thanks!

oh okay thanks man !

You should be opening 16 instances of HCI memtest, so that it can pass over your RAM faster.
Im using HCI memtest pro, and automatically open 5 instances when i press start, automatically using 96% ram usage. do i still need to open 16 ?

Hi guys, I'm new to ram overclocking as I just started to explore it after I build my ryzen PC weeks ago.

One question: assuming my 3200CL14 16gb bdie ram kit is cappable of running 3466CL14, is more VDIMM applied always improves the stability of ram overclocking? I mean within the safe range, like <1.5V. If it's true, is it good to start OC by setting the VDIMM to 1.5v and test its limit? As it can take away VDIMM as a variable to take care of.

You don't have to, but you'd be wasting your time if you didn't. Your 2700X has 16 threads. May as well use them all.

CMK16GX4M2B3200C16

anyone knows the stable timings for CMK16GX4M2B3200C16. this is samsung die. ryzen 5 2600 asrock ab350m pro4
xmp settings doens't boot/bsod.

Thanks

I've posted few posts above with nearly the same issue, so far no solutions :S

EDIT: Actually I've been experiementing with voltages and stuff, I managed to get it working and perhaps you can tooo. Not going to waste time with boring ***** so straight to the point... I've set "XMP profile 1" in bios and then changed DRAM voltage to 1.40, anything bellow that didn't work for me.

Hi all.....

I'm a bit of a noob when it comes to OC'ing ram. I read through this thread a while back...and the search function isn't the greatest since the move.

I ran the HCI/Google Stress test at 3400mhz....passed both. Thought I would try 3466....the Google test says Thread 7 found 1 error, and Thread 10 found 1 error.

Here is a screen shot of one of the errors....I can't make head or tails out of it....thought I would post here and perhaps get some guidance from more experienced OC'ers.

View attachment 195065

I'm running the 2600x(stock clocks), fixed core voltage at 1.325v and the SoC is 1.150v. I'm using the GSkill Flare X Series F4-3200C14D-16GFX. I set the timings manually using the Ryzen DRAM Calculator. I believe I'm on the "Safe" settings profile that it generated. I'm on the Asus Strix X470 Gaming board.

Any info would be appreciated.

EDIT: I believe I have the DRAM at 1.45v

EDIT II: I was on the "Fast" profile, testing "Safe" now.

Forget I thought you were running at 3200 I'm going blind, lol. I deleted my comments.
