Reacting to people's RAM timings episode 3

[@mikezappulla4092]

Thank you for doing these, always learn something new.

[@nwk6258]

This man fucks.

[@mikezappulla4092]

These are awesome Buildzoid. Even though you sound annoyed at times doing them, we learn a lot!

[@0vers33r1]

Amen to that

[@buddyb4343]

Yes, he does sound annoyed at times . . . "CAS means nothing" over and over. But then he puts up some bench marks, CAS 28, vs CAS 40, (if I remember correctly) and the benchmark (primarily relating latency I believe) goes from 9.856 to 8.9XX something something. Ok, a lot of very nuanced technical information there, flashing by in the benchmark dialog boxes. Now, what can I do with that? Buy cheaper memory, get better frame rates? Or is it only a better benchmark number? I appreciate the basic effort, knowledge and information involved, but hearing that "CAS doesn't matter" 10 times, is not useful. MO anyway.

[@dedbeet5845]

I love it. The more annoyed he is the more I learn.

[@Stalast.]

36:38 - incredible that you instantly noticed what is a literal mistake in my timings. tRDRDSCL and tWRWRSCL were indeed both meant to be 4! I think somewhere down the line after updating my BIOS and re-entering in my timings, I must have missed one because I checked my BIOS now and tRDRDSCL was left on auto haha. Thanks for the suggestions and excellent information as usual!

[@kajurn791]

Most interesting setup was the last one. There are only so many B-die + Ryzen setups one can look at before getting bored.

[@nastassia19]

I'll take anything that isn't about the most recent Intel/AMD platforms at this point.

[@NotThatGuyJD]

That was my CJR, yeah some of those tertiaries are at auto. Was my first foray into Mem OC and CJR guidelines were hard to find. Was scoring around 275 on IBT and it passed HCI at 800%.

[@billkillernic]

Why not doing a video explaining the relations of the timings and what "algorithm" to use for inputing values at each and test them and also what impedances to try and why to use the specific values? This would make a lot more sense and help a lot more people than to just comment on random timings which ok you elaborate somewhat on your comments but its confusing in that way for the uninitiated to understand what to do for his kit.

[@ninjabus7454]

Fixing up my memory timings improved performance by 23% over baseline, these examples are really helpful. Thanks!

[@SgtBluntman]

Thanks for another ram timing react vid. It actually helps me understand what i should be looking for and how i should be tuning.

[@gamingvibrations5320]

LOL, getting straight into the video and immediately just bashing people's "generic b-die timings". This is why I sub.

[@blufoxful]

I'm the one at 17:50 Its a 3600 Cl16 B-Die kit. TRFC at 300 was giving me random blue screens every now and then. Raising it just a bit fixed that. That's why it's 324 unfortunately.

[@ActuallyHardcoreOverclocking]

Makes sense. Very strange that it wouldn't do 300.

[@blufoxful]

@@ActuallyHardcoreOverclocking Perhaps it's my old board and 7700k not being able to handle the kit. Would explain why it refuses Cl14 all together. I'm considering pointing a small fan at the ram kits.

[@Pro4TLZZ]

My vipers didn't like 300 either. 310 was stable

[@blufoxful]

Quick update. I increased my fan intake fan speed close to my ram and now looks like 300 is stable so far. I hope it says like that.

[@ravtastic9802]

bz wrt curve optimiser, the only stresstest i found that works to determine stability for idle by using stressed loads was OCCT's small, variable, AVX test cycling and swapping (ie, core 0 singlethread, then all cores except core0, then core 1 singlethread; by checking both cycle and swap options at 10/5s each) i had a setup that had passed literally an entire day at work doing corecycler on both prime95 all sorts of sizes, ycruncher tests, all of it no errors; yet closing it and youtubing for a bit it just blackscreens. the unstable setup also happily did a couple of days of X265 encoding without crash; and gaming without crash. OCCT avx showed immediately that cores were spewing errors galore. and only once occt was satisfied under avx singlethread load, did the idle blackscreens stop. like i was amazed some cores passed corecycler/p95/yc for over 12 hours with no issue and spewed errors instantly from occt. like to the tune of one core having to go from -21 passing to -8. can reccommend. went from pulling my hair out over multiple full days of testing to fully dialed in and rock stable within an hour. i dont think the recommended corecycler methodology of using SSE workloads to stretch the boost is viable. (occt also passes SSE with way too low an undervolt) it just lets too much instability pass that avx will kill it. i think better to just pump EDC till it can mostly-sustain max boost on a single core with avx. between cycling between single-thread and all-but-one threads this keeps the cpu hot to ensure pathological voltage requirement. also as a side note, once i was occt stable on curve optimiser, i could just put the boost override straight up to +200 and no issues whatsoever. i somewhat expected the curve would need backing up a bit but apparently nope. corecycler may well work if you use avx aswell. but it doesnt keep the cpu as hot as alternating between ST and mt.

[@hyprjay]

Thanks man. It’s pretty cool to see u keep breaking down these numbers. Very informative with ur way of thinking.

[@Kazyek]

36:17 I have the same board and it set crazy VDDG and VDDP voltages. I found that lowering those helped me tremendously. Also, tRFC doesn't calculate tRFC2 and tRFC4 properly, I have to dial them in manually with the formulas or else they are fucked up, as seen in his screenshot

[@0vers33r1]

Thanks and respect to the smart guy at the end with the 5700G @4.9Ghz and 4733 cl18 ram at 1T LOL That's one fully pumped system and exactly what i want to build lately xD

[@Toasty27-q6w]

I was *literally* looking for this on Twitter earlier in the day and figured "ah, well, I'll see it soon I'm sure". And then I completely missed it. You're too fast at getting these out man. 😭 Spent three to four weeks off and on working on my current profile and finally got it where I want it. Guess I gotta wait another month for feedback.

[@thatguy7595]

Video idea: what is memory training, how it works and why do we even need it if we are already setting bajillion timing settings in BIOS?

[@Constantin314]

tnx for roasting my RAM, too, BZ, 35:34. they;re B dies but i think pretty not good ones. the primaries are at they're best, can't go lower with them, and at the secondaries, still some refinements to do, but it;s good to know that this random RAM OC failed is normal for msi boards :))

[@LinkStorm13]

You could do a vote-system for those videos, where you let the community vote on which timings look interesting on twittrer, before you give your 2 cents to each of them. That way we would have less generic ryzenb-die configs and hopefully no 3200 cl16 xmp setting in here.

[@Ben-ld1qi]

My guess for some of these oddly specific tRFC numbers are increments of tFAW 16 i.e. 256/272/288/304 etc... Is it possible to find out if tRFC really rounds up the nearest tFAW multiple or is that just one of those RAM overclock gospels?

[@Evilfaic]

After watching this, I decided to OC the RAM in my daily system. Bricked my board and corrupted my OS. So that was an expensive lesson.

[@TKIvanov]

Lmao, howd u manage that?

[@_megazz]

Bro, how do I always miss these on Twitter? Will you do another?

[@LLeonardson]

Thank you these types of videos are pretty helpful.

[@Drumaier]

I had the same issue with curve optimizer passing any hard stress test only to crash when doing nothing. I think Windows default power management is the one messing things up, because once I set all power consumption option to NEVER (example shut down disks after 20 min of inactivity), the issue was gone for most part. I can't be 100% sure because I was testing differnt things and having shut downs related with the CO....but not when idle as far as I can remember. Anyways I think the -30 offset that seems to be the generic number is very optimistic unless you have a platinum sample, great cooling and great overall bios settings. Going for a mix of -5 and -20 depending of the needs of each core seems to work better. Btw my ram sucks, Kingston "fury beast" Hynix AJR, won't recomend for OC or great performance.

[@strongforce8466]

You mention the curve optimizer..interesting, I been having this reccuring freeze problem.. if I get crashes only in idle, randomly freezes my windows, I can still move mouse and even use softwares for a bit but the windows bar at the bottom is frozen, then eventually it freezes, have to hard shut down (can play hours without issues, only when alt tabbing it can happen sometimes) I tried so many things, thought it was my memory OC, but it happened even with ram on auto (default speed). I tried to put a 4650mhz full core OC last night as I was suspecting it could be related to boost or eco mode, 8hours fine on realbench, I open a browser and instantly get a freeze...

[@Janni_S]

Hi @buildzoid and thank you for commenting my settings from ~9:00-11:30min. you said that my Drivestrength is kind of whack like 20-20-20-20 on my unify-x but it sets it on auto. should I change them all to 24 or so? This maybe helps to stabilize cl14? thanks in advance :)

[@ActuallyHardcoreOverclocking]

I guess MSI must've changed that in a BIOS update at somepoint then. It can't hurt to try all 24s.

[@anub1s15]

i kind of wonder since you mentioneed that GDM off / 1t / 2t isn't much of a difference if that may be kit type dependant? with my current B-die I fully agree I put a bunch of time in to getting GDM off/stable at 3600Mhz but when I checked the latency it was within margin of error where on my previous kit (hynix CJR) getting GDM off was by far the biggest boon to latency out of all the tweaks I tested knocking off 2ns...i kinda expected the B-die to have the same appreciation but :( though my previous kit was also 2x16 where my current is 4x8 (3900X) so maybe that's why? or it has to do with the setup times I'm using...i honestly have no idea what it does or what I'm actually manipulating by changing it but I do know that 0 was instacrash 63 was almost instacrash and 51 seems pretty stable but might try lower to see if that results in more stability when I try to tackle TRDRD and TWRWR as recent tweaks destabilized my settings there >.>

[@exoticspeedefy7916]

I think 2T GDM off is better than GDM on with 1T on many duel rank systems. I tested mine and 2T not only had better stability, but lower latency than GDM on 1T. So yeah single rank you DONT want to be running 2T however

[@Multimeter1]

So for all ddr5 potential owners there is an issue with Samsung 6000Mhz CL36 Kits and CL40 from Gskill. MSI carbon and Strix E have issues running it at xmp or even fine tuned. Hope billzoid can expose this issue and call out these manufacturers

[@anub1s15]

really informative to watch, spent a couple weeks by now playing with my ram but seeing what other people are doing with similar kits makes me want to dive back in and try some things. though I do find ram testing to be the hardest thing ever >.> used to do what I call "short" tests but what I got "stable" with that led to memory could not be read errors wile playing games, now switched to a "long/normal" test duration and I'm ending up a lot more stable but I can still pass TM5 with the extreme777 preset and games will occasionally still run in to memory could not be read errors, doesn't go away until I back off certain timings...hard to test for when you need to change something then try to go hardcore in to gaming to really test if it worked for about a week :P but to my surprise my cpu's minimum fps in forza horizon 5 went from ~79 > ~91 so yay progress/results (as I don't know what is up with aida 64 but stock vs tweaked to hell and back = just some bandwidth differences for me latency is not changing at all >.>

[@ActuallyHardcoreOverclocking]

try stress testing the RAM while the GPU is under load. When playing games the heat from the GPU can heat up the RAM which can cause it to error at settings that work at lower temperatures.

[@anub1s15]

@@ActuallyHardcoreOverclocking >.> that makes way to much sense tbh. the ram is practically located above the GPU VRM so when hitting it with a load for a couple hours....yea ic how that might cause the temp's to change to the point of causing a problem (my exhaust is also only on top so I'm for the most part pulling the heat up in to the ram which....probably is not helping :P oh well maintenance soon where I'll be upgrading the fan's with something more silent that I can run faster hopefully moving enough air to....lessen that problem (my current fan's are...in the grand scheme of fan's not actually that good at being a fan :P....at least not a silent one while still providing decent airflow/pressure), case is a Lian li 011D with a bottom/side intake and top exhaust so to move air around the CPU area basically requires just ramming as much air in to it as I can....should work out I think :P

[@malphadour]

Quite a few 5000 series ryzens won't do 1900 bclk. My old 3700x did, but my new 5700x flatly refuses to run it. I was highly disappointed, however other than that the chip murders the 3700x so still happy. Also..I never see these things until after you review them - have some rev-e timings I hope you would like.

[@Raivo_K]

My 5800X3D wont do 1900 either. Tho one would assume it being the newest and B2 revision it would do it but it's the same as my old 3800X stuck at 1866.

[@dainluke]

Don't take this the wrong way, but didn't you mention in a few of your older videos that setting tertiaries is tedious and not always worth your time? It just seems like you're putting an awful lot of emphasis on them in these videos, but you never really stress the importance of setting them. I would wager that most of these dudes don't set them because it's a hassle to have to worry about them and re-run memory tests. The PC overclocking/enthusiast space should be a positive environment where we learn from one another. If these videos are meant to have strict requirements then please mention it. I felt like you went really hard on a few individuals for little to no reason. A lot of submissions are probably just because they want a feature. It's a matter of acquiring good bins and investing time. That isn't really something most individuals will be able to manage.

[@Wasmachineman]

bz roasts whoever he wants m8, what do you think these videos are about?

[@dainluke]

@@Wasmachineman My apologies, I had no idea these were roast videos. I thought this was a science and technology channel.

[@MrPunkassfuck]

You can't handle an ounce of critique? If my timings were shit, I'd like to know. Honestly, never go to university. You'll quit just because the teachers call you out on your shit. If it is a good Uni. Honestly, if I was Buildzoid and seeing the same mistakes made time and time again...don't people read about how to do RAM OC? You might even learn something. You can see him mentioning secondaries and tertiaries in just about every video about RAM he overclocks IIRC. I would say, watch more BZ videos, watch from beginning to end. And even then, do your own research. Find something written about timings, explanations. Look through the specs of your RAM, the manufacturers PDF. It's like 200 pages. And do your own testing. Lots of it. Only you have your hardware. We can't do it for you, even if we wanted to.

[@Koeras16]

@@dainluke Most of those settings don't do as much as one might think in day to day usage. XMP is honestly fine for most people. Dig deep into those tertiaries if you appreciate and enjoy the process. This is by consequence just a video about optimal timings and comparing memory setups of different platforms. And yes, it is extremely tedious to optimize tertiaries and probably never will be "worth your time".

[@dainluke]

@@MrPunkassfuck I wasn't featured in the video. But other than that, I've watched almost every BZ video since I found him in 2019. He has said on numerous occasions that he doesn't think setting tertiaries is worth the possible instability and effort, if you're just trying to get a decent OC rock solid (in terms of data rate, primaries and secondaries). I do OC my own stuff and I enjoy OCing, I also never ask for help because I don't expect help. I adopted D5 and I've been doing my own settings for months now because there was no help to be had. There's a difference between criticism and shitting on someone. A fairly large one at that. It's okay to be knowledgeable and to instruct someone when they're making mistakes, but I don't think anyone who submits XMP or mediocre settings realizes what they're signing up for. He should explicitly state it. That way it doesn't just become a roast fest. Your comment is tremendous. The pretentiousness. It's astounding how you just assume I've never read a data sheet or researched RAM or OC'd myself. Amazing, truly. No for sure bro I know nothing. I can't be as cool as you and your crew of RAM OC Gods running 7200 32-42-42 with your 57X1/55X3/53X8 12900KS configurations.

Hey @buildzoid. TBH I've stopped watching after first example. There's nothing to gain from it for me. How do I know? Because I've watched first two episodes before and it was the very same tone. Waste of time. Let's cut to the chase - I have generic ryzen setup - some bad b-die bin and 5800x. You said on previous episodes "it's not interesting, it's boring, etc." yeah but let's face it - there's a lot of people with such "generic" setup and timings taken straight from DRAM Calculator. When you want to improve and get somethin better (than DRAM calculator) from your kits, you go to the youtube, buildzoids channel, watch reacting video, seeing setup like yours "oh lets hear what he says" and you saying what? Timings tight, timings loose, fine Voltage, le fin. Nothing more. Instead of saying: try changing it, try changing that, I would've do this that way, etc. Don't be that guy.

[@meppie1922]

On Ryzen it really doesn't matter. The only gain you get is instability and erratic behavior. Just get 3600 kit with tight timing and load docp settings and leave everything on auto.
