Hi everyone, currently I managed to get a stable oc with blck @ 102.4, vsoc @ 1.012v and vcore offset -0.06250v then ram [email protected] with timings of 2666Mhz safe V1.
I spent many hours playing with the ram getting stable with timings 14-15-15-15 3340 / 3481Mhz but not satisfied with the results compared to 3276C14 and increased tension.
I managed to pass TM5 with maximum 3549mhz CL 18-18-18-18 ... but not taken into consideration.
So I tried to keep the timings unchanged (timings 2666 safe v1) and increase the ram frequency.
After passing TM5 @1usmus v2 with 3340mhz @ 1.36v and the same timings I tried to pass ibt without success by raising step by step vcore (up to -0.0250) and vsoc up to 1.1v.

Could this mean that it is the cpu that is at the limit and I should raise the timings?

I need some guidance to solve 'soft crashing' on certain games like Battlefield V or Apex Legends. Those games randomly crash into desktop without any error message, system freeze, or BSOD whenever I use 3466C14 safe preset from the calculator. The 3466C14 preset has proven quite solid with TM5 and HCI memtest for over 1000% multiple times though.



I found that using direct fan cooling on the ram kit decreases the crash rate but still happens while 3200C14 safe preset shows the perfect stability on both gaming and synthetic tests.

system cooler setup:
-140mm X 2 fans on top, 120mm X 3 fans on front(with a cpu radiator), and one 120 mm fan on the rear
-80mm X 2 fans on ram kit


what I tried :

-increased DRAM voltage up to 1.42 ( I have been able to pass TM5/HCI memtest from 1.4)
-tried each step of SOC voltage from 1.0 to 1.1

-turning on/off PBO (with/without negative voltages, too)


thanks in advance. any advice would be really great.





*edited for adding more cooler setup info.

well, it is answering my own answer. the best advice has already been in the 1usmus's memory overclocking guide;

One of the more interesting issues I encountered during testing was that the memory had a tendency to be unstable while the processor was running at 4200 MHz.
Switching PBO from 'enabled' to 'AUTO' in BIOS (does this mean I am turning PBO off or toning it down a little bit, I am still confused though) has completely solved the random crashes. I guess being less aggressive on XFR curve has made the memory overclocking much more stable on gaming.

Announcement DRAM Calculator for Ryzen™ 1.4.2


Key features:

* Motherboard Topology. Global reprocessing of procODT / RTT recommendations. Maximum accuracy is guaranteed only on AGESA versions 1.0.0.4c and newer.
* Global reprocessing presets (timings/voltages).
* Improved support for systems in which more than two memory modules.
* Improved algorithm for calculating Debug profiles.
* Improved support for HEDT systems.

Date of the release is difficult for me to predict, as I am currently negotiating with AMD about CAD_BUS. There is a dependence on how these settings change from frequency. And I have a great desire to share them with you.

Biggest step in improvement in an already great tool! Im in need to try it! Maybe i can finally make stable my bdie RAM in my X370 board above 3200 fast settings.
Im looking forward to it.

Just picked up a set of new rams and while these work out of the box on my C6H and 1800x at 16-18-18-38-54, wonder if these are Hynix CJR rams for the purpose of using the DRAM Calculator as there are some ?? in the Part Number.



Anyone else come across similar ram type before?

Could this mean that it is the cpu that is at the limit and I should raise the timings?
To be able to pass IBT I had to increase the ram voltage compared to what was required by tm5 (also a bit the vsoc) so the settings are with bclk at 102.4 vcore -0.0625v vsoc 1.037v (tm5 was 1.025v) with ram at 3340Mhz @ 1.40v (I try to lower it, for tm5 it was enough 1.36v).
Is it correct that it has proved necessary to increase the ram voltage?

ps: b-die

TM5 0.12 v3 config

https://drive.google.com/open?id=17u_88vsjraTDw5_wI6gJY05peEicbBsQ

after the first start of the program, delete the file cfg.link otherwise, v3 config will not work
p.s. you only need to delete this file once and only at the first launch


* fixed test crash , when a certain cycle there was a shortage of memory
* 2 new test added
* test number 14 was temporarily removed, because there were few situations in which an error was found there
* special config for HEDT with 4 channel mode

Thank you!
Are 3 cycles sufficient for long term stability or should we increase it?
This is your wish, but I think that 6-9 cycles is the maximum for stability testing, the test demonstrates very high efficiency.

Hi. I'm looking at some 64GB memory. Does anyone know if these rams are Samsung B-die?

"HyperX Predator Black 64GB kit 3600MHz DDR4 CL17 DIMM XMP Desktop PC Memory (HX436C17PB3K4/64)"
"Corsair Dominator Platinum RGB 64GB (4x16GB) DDR4 3600 (PC4-28800) C18 1.35V Desktop Memory"
"Corsair CMW64GX4M4K3600C18W Vengeance RGB Pro 64GB (4x16GB) DDR4 3600 (PC4-28800) C18 Desktop Memory White"

I'm sure 1usmus you are near perfection but in fact yeah recommended procodt with 1.4.1 are wrong for me but alt1 was smooth . Between 1.4.0 and 1.4.1 i can push my poor G.Skill F4-2400C15-8GNT from 2933 cas 16 to 3066 cas 16 !!! The worst in my case is that if i don't use your am4 dram calculator my rig isn't stable Oo got bsod bsod bsod at 2133 ....

Thx a lotttttttttttttttttt
