Ryzen DRAM Calculator by 1usmus

[Cowboystrekk]

I had a problem here, cant use my pc right now, but xmp with 4000 16-19-19-39 runs with 1.45v but latency increases... ill try your steps once I get back...

thx for your feedback.

If latency increases then soc voltage is too low or vddg iod voltage is too low. Try upping soc voltage to 1.12V, that is enough for me to get proper latency and beat 3800 by 2 ns

This is Really Amazing here been using this cpu about a week with the new bios update, this bios update has fixed my issue, with my cpu doing single and double restarts. About to go play with some timings and see if i get any better on numbers.

You can decrase tRCDWR.
I think you should try this setting.
tCL 14
tRCDWR 8
tRCDRD 14
tRP 12
tRAS 21
tRC 36

tRDRDSD/DD 4
tWRWRSD/DD 6
Maybe you can go below 60ns.

Sorry for my bad English.

This is a good video I found about how to use this stuff.

I'm waiting for a new version. With Zen 3 we should have had 1.7.4 a while ago. Settings for 4000+ would be appreciated!

i think 1usmus abandon this project long time ago.

I couldn’t get it to work for me, but then again I haven’t used it since December. The values it spit out were great for blue screens and hard crashes. I am using bdie so maybe that program would be better for everything else? I just know what I know, and I still have some noob in me.

Where you are at buddy, I'm pretty sure DRAM Calc ran out of things to teach you a very long time ago

Yeah, not for me specifically, but I think it would be useful for many Might help me stabilize 4133/2066

anything similar now?

sorry no clue. But you can still use the calculator as a guide. although it will be a trial and error

The calculator has only one serious problem to my experience using it. It predicts silicon quality margins would be minimal for the SOC voltage needed to allow the rest of the settings to work stable. So, while most settings prediction work exactly as shown, the SOC V needs to be tested individually by anyone wanting to apply the settings shown in the app. In my case to work stable on my ram being at 3333MT/s c16, instead of 1.02-1.03V for the SOC, I needed 1,15V to make it stable with my RAM's voltage at auto being where the app suggested (1,35-1,36V). The SOC's voltage needed depends on the mem controller in the CPU and it is a silicon lottery thing. If the app suggested that it would be almost perfect.

Hello, Guys I have problem with Gskill Trident Royal Z 4x32 (2 pack dual 32x2), i have 5950X i tried config the mem with 2 mem and dont have problem with the xmp 2.0 (3600mhz 18-22-22-22-42), but when put other 2 the sistem showdown and restart all time, I config with manual and put 3333mhz with 20-22-22-42 in 1.400V.

How can sent best config for this cute piece of shit ?

Vcore : manual 1.2
PBO : ENABLE
MAX CPU BOOST CLOCK : 200mhz

my setup :
Asus rog crosshair hero VIII
AMD Ryzen 9 5950x
Gskill Trident royal Z 128gb (4x32) 3600mhz 18-22-22-42

Cheers brothers !

Increase the SOC voltage first up to 1,17-1,18V and check stability. If it is ok then lower it step by step.

this is for latency ?

SOC 1.17 and try lower 1 by 1 or by 1 for all ?

SOC Voltage increase is needed for stability where the previous setting isn't enough. When you find a stable voltage setting (1,17 for example) you can try the lower step one by one in order to find the lower setting while being stable.

Hello bro ! I up the SOC in 1.15 and after this and check this but the result imposible take more tras .... after this only reset and clean bios.

You have more idea o best way for this, i check other users but not have comparation with other user with 5950x and this mem.

Cheers and thanks for you knowledge

Try the SAFE settings first from the calculator. Maybe the chips in your ram aren't all good enough to be stable for the FAST settings. Just an idea.

that is the SAFE, but i tried move 15 CAS and reset all time, so 16.
all before 42 is take one by one (i was do it this all nigth lol XD), but when try move tRAS to 40, reset... so i dont know if needed move the others before tRAS.

Thanks for your help bro, I really apreciate.

Hynix chips and AMD CPUs don't seem to like odd CAS timings, at least from my experience.

I've seen posted many times that if you want to run 4 sticks of ram you should by a kit of 4 sticks of ram. 2 sets of 2 sticks just don't always play nicely together even if they are identical kits. 4 stick ram kits are tested to work together.

 

[HD64G]

I suggest you try those settings below with 1,15V initially for the SOC instead of 1,05V. If proven stable lower that step by step.

I use to use this calculator tremendously over the yrs but not anymore. The latest bios for my motherboard has ironed out a lot of kinks in memory OC on Zen+ at least. Although this newer bios is optimised for Zen 2 & especially for 3, Asus so far seem to have done a good job maintaining OC features on older Zen revisions. Leaving a lot of stuff on auto does a heap of good in ensuring stability during stress tests I've found.

You managed to get 3466 on Zen+ so you're already an expert in my book. No use for the calculator anymore.

 

[Deleted member 67555]

Me with Zen+....
2667 Yes, 3000 nope, 3200 nope, 3466 with tight even numbers Success....lol

Really due to bios maturity on X570.
