Ryzen DRAM Calculator by 1usmus

I changed my MB to Gigabyte B450m DS3H (it has a vrm heatsink and cost 80usd) . It was supposed to be used in a cheap apu-setup I am building for someone else, but thought it was worth a shot. After some testing I now run my Crucial Ballistix sport 3000cl15 2x8 at 3733cl16 at 1.32V 100%. It ran at 3800 also, but infinity fabric stops at 1866 on my MB. Still I am very satisfied. Performance is 5-10% better in bench and games at lower settings compared to Asus tuf B450m gaming plus (110usd) with ram at 3266cl14.

Either E-die support is just terrible on the Asus board (qvl makes me wonder of that's the case) or it's t-top which also could make sense since highest bootable speed I got was 3333cl14. After reading Gigabyte qvl it seems like their ram support is far better than Asus on these 2 board. Dissapointed of Asus this time. A 30usd more expensive board being outperformed like this.

On a budget-setup I'm building with 2400g, Tuf B450m gaming plus and Micron E-die 2x8 I wonder what I should do about gpu voltage? Dram calc gives me no clue. I can run 3533cl16 stable in memtest, dram test etc, but if I try to run games everything above 3200cl14 crashes. I have tried both the Zen 1 and Zen+ settings, everything at 3266, 3333, 3400, 3466 and 3533 is stable in cinebench, memtest etc except games.

Stick to 3200 cl14 then, simple.

It's just games that uses iGPU that are unstable, my question was if I can adjust iGPU voltage to get stability above 3200cl14

Hi! I have DDR4 'HX432C16PB3K2/8' 3200 Mhz (hynix j-die) and I want to OC them at 3600 Mhz. I should use Hynix CJR/DJR in DRAM Calculator?

DJR is added but not yet functional, at least at 3600. CJR is still the only high end Hynix IC supported in the calculator right now. Quite honestly though, CJR and DJR below 16-19-19 at 3600 is quite rare, so the CJR profile has worked okay for DJR all this time.

If DJR is a refreshed and refined version of CJR, then JJR is the highly suspect, gamey CJR that isn't binned well enough to be CJR.

You can give CJR profile a try or AFR, but I predict you may have to loosen up those timings and take the time to dial things in manually to find stability. I wouldn't go in expecting something like 16-19-19-39 3600 out of JJR. Loosen up the CAS a bit and see if it can reach 3600 first.

hi everyone - i am out of ideas here, as i think i have really tried everything to get stable, even at the safe setting. I am in dire need of a sanity check.

First things first though: I am running a 1700x at 1.375V 3.7 GHz on an aorus x470 gaming 7 (i know, motherboard is op but i got it really cheap used to upgrade to 4700x later) and bought some 3600 MHz toughram to be able to hit the maximum fclk at 1800MHz with 1:1.

Now, neither the original xmp nor the recommended safe settings are anywhere near stable and i need to go down all the way to 3200 to play games for more than an hour. The only setting i couldn’t find in the BIOS is BGS, so that is unchanged. Is there something wrong with me or my hardware or am i just the loser of the silicon lottery?

First of all, please use the Print Scr button on your keyboard to grab screenshots, then Ctrl+V them here, as what you've uploaded is really hard to read.

As I can't read your screenshots, it's a bit hard to make any suggestions, BUT, you have a Ryzen 7 1700X which most likely won't accept memory speeds over 3200MHz. Anything beyond that, is pure luck, as the first gen Ryzen CPUs didn't have a great memory controller. 1800MHz is only possible on some 3000-series Ryzen chips and anything above 3600MHz isn't guaranteed.

Do you have Hynix CJR or Samsung B-die? You set up for Hynix in calc but the reading on the right side says Samsung. Did you use the report from Thaiphoon burner? If youcare able to run 3200cl14 with good timings that will give you really good first gen performance.

Thanks for the quick replies, sorry for the pics, i was on mobile and those were the ones i used to transfer to bios - here are some actual snips - the thaiphoon pic in the photo was from a tutorial vid in the background.

Does either of you know what the relevance of BGS is? And am i mistaken for aiming for 1800 MHz, i thought that was basically standard. Also i heard that ryzen has problems with even timings so wouldn't cl14 be problematic?

Read @TheLostSwede post, you're limited by 1700x memory controller. 3600 is probably impossible. Try 3200 safe first. If this proves stable move up to fast and validate stability.

 

[user556]

On the CPU side, you can go all-cores 4000 MHz by manually locking the core voltage at default, which is 1.35 volts, or just above that if you want. I've got my 1700X at 1.36 volts. This prevents the BIOS from automatically bumping up the core voltage to stupid high amounts when you then manually set the multiplier to 40.

On the DRAM side I probably can't help a lot since my XMP is only 2800 MHz and automatics worked fine out of the box.

Is there any plans for the next version to add ddr4 speeds 2133 and 2400?? It would be great to have optimized timings for those speeds also.

Such a great tool.

Cheers

 

[marstein]

I like the tool but it is unusable for me. My Gigabyte Aorus AM4 bios uses slightly different names for the parameters, in a different order, in various screens. Sometimes in two different places...
great would be if there was a translation layer that would take the values and show them in just the way they have to be entered into the BIOS.

 

[Megatron]

My post is related (Gigabyte Aorus Elite), I have most settings input and from my OC results they are in the right places. Although I agree, it took some searching to find the correct values from the two pages of DRAM calculator. I have one setting in the bios I was going to post a screenshot of but I think its best if I take another screenshot with the option enabled to show the subsequent options. I will take some more screenshots of my bios ram settings and post later. I will attach some screenshots of DRAM calculator for Ryzen so you can verify.

Nobody runs DDR4 at speeds that low.

I've taken screenshots of my bios and I already posted the settings I'm using from DRAM calculator (the settings for 3666MT/s although I changed the memory and infinity fabric to 1:1 @ 1866Mhz for 3733MT/s). When I got to 1866 my infinity fabric divider stepped in on auto settings IF/2 x memory frequency. I tested that with memtest86 (https://www.memtest86.com/download.htm) on test 7 as that is the fastest way to check stability and you don't need to enter windows and risk data corruption. So when I changed the IF to 1:1 and was no longer completely stable I knew it was to do with the infinity fabric. I checked HWiNFO to see what my current IF voltage (SoC) was and added 10mV to that in the bios. It reads 1075mV in HWiNFO and is lower than I expected.

I was planning to test 3800MT/s or 1900Mhz IF/MF 1:1 today but got distracted.

In screenshot 01, I'm not sure about VDDIO is that voltage block> VDDG IOD? Would that mean VTT in my bios corresponds to main voltages> VTT ddr Voltage Max?

On screenshot 08 and 18 it has VDDP voltage 1000mV and 855mV? It can't be both! It says under debug voltages> VDDP voltage recommended 900, alternate 855. On screenshot 20 (PC health) it says CPU VDDP = 1.116v which is what HWiNFO is reporting for current, min & average values with a max of 1.128v.

On screenshot 19 my bios has 700mV (manual) for VDDG CCD and under Voltage block it says 1.025. Same for VDDG IOD.

On screenshot 16 it says SoC voltage and I've set it to 1080mV. In HWiNFO it says CPU Vcore SoC = 1.104v (from board I think) and SoC is 1075mV reported by CPU.

On screenshot 13, the settings are duplicated under advanced memory timings (screenshot 04).

Just FYI the numbers on the end of the filenames remind me which version of Gigapixel AI I've run it through and the settings). For these photos though I think it was a waste of time. Never seen it take over a minute to process a file ( maybe takes longer with a larger filesize input, I was scaling down).

On screenshot 02 I have DRAM Terminiation on auto (0.6v) but under main voltages > Vref (CHA/CHB) it says 0.71v. Am I right in relating these two settings?

I just googled Dynamic Vcore SoC and found this:
https://www.reddit.com/r/Amd/comments/6xqv2q So I can adjust my SoC voltage without locking my IF to run max speed? I'm going to go watch that TechYesCity video:

That hardly makes it useless. You also don't have to change all the settings. The key ones is the regular memory timings and tRFC. A lot of the other settings can be left on auto.
See this post of what I have changed, for exampel.

Ryzen DRAM Calculator by 1usmus

Is there anyone here who could give a novice a hand? This is my first build in like a decade and I bought the memory I did because I wasn't comfortable with doing timings manually and several places I read/watched said this was a good kit to just stick in, set xmp, and go. Unfortunately it won't...

See above, you don't have to enter every little setting, as a lot of them will have zero effect on system stability.

 

[Taraquin]

TheLostSwede: Also TRRDS and TFAW should be chaned, they affect performance quite a bit. Lowering them from 5 and 20 to 4 and 16 improved avg fps in SOTTR bench with 3 fps and min with 4 fps. Running on autobthey often end up around 7-8 and 30-35 which deteriorated performance even more. Command rate and TRAS/TRC should be lowered as well since the latter two to my knowledge is tied with tRFC and keeping them at auto often makes it impossible to lower tRFC as much as wanted

 

[Megatron]

I made progress, I entered those values which I found hard to deal with at first (with no help). VDDIO is default @ 1.2v and VTT_mem = VDDIO * n/256 where n is in the range 1 to 256. I just had to use my phone's calculator to narrow it down as near as possible to the DRAM calculator range.

Also I copied Buildzoids suggestion for PBO but I had to tweak a few settings to enable it. See here:

I've not followed the overclocking guide here just DRAM calculator and some settings I made to make the infinity fabric stable @ 1866Mhz (lock IF to 1866Mhz, was lagging without + small increase to dynamic SoC voltage).

I think this is the pick of the bunch (updated chipset drivers from AMD (2.04.04.111 + a powerplan https://cdn.discordapp.com/attachments/612647199737774104/669860910659141672/Powerplan_V4.rar ):

Just installed 32GB (4x8) only to discover that two sticks were Samsung B-die and two were Hynix A-die. Outwardly the specs are identical 16--18-18-36.

Is there a process for optimizing this type of mixed install?

 

[mechtech]

Unfortunately my 1700 does on my gigabyte AX370 K3 gaming and my 2133, 2x16GB of ram. I was hoping if those speeds were added I could at least optimize the timings. I do more workstation type stuff (autocad, etc.) on my desktop so I prefer stability/reliability over bleeding edge performance.
