Now imagine if cpu manufacturers where to do this: Rating their cpu's at the maximum frequency they could run on ln2 in the best possible scenario while only using a single core.

[@KaitlynFedrick]

only specific cherry picked CPUs as well

[@qlum]

Hmm seems intel is actually starting to do this with their 28core xeon running 5ghz.

[@jakenorthand1755]

They kinda already do this. For the most part CPUs come from the same silicon and are binned using stress tests and altered to become there final CPU. Doing LN2 for all chips would take forever and cost a lot to show maybe +200 mHz on some chips.

@@BadMannerKorea Way late but here's a shot in the dark. I have a 4500 kit I'm using with my intel i5 10600k. Only the fancier Intel CPU models are supposed to support these higher speeds. I currently have mine dialed in at 4200 with safe voltages. Do you know if I'm putting my CPU at risk regardless? I'm assuming you are using Intel if you are buying a 4400 kit but I guess you could be rocking a Ryzen and dialing it in to IF with tight timings. Thanks!

[@stevethea5250]

@@FakhriAunurrahim Them not being on the list, just means they haven't been tested with the mobo. This could account for the issues. In this case, all you can do is test and see how you go. Beyond 2666 you really want to use only the 1.35v for further speeds. Try this: Rather than set timings manually, leave all on auto. Set the voltage to 1.35, and only change the speed of the DIMMS. see how far you get, but remember to run memtest to test each speed setting. The purpose of leaving the timings on auto, is to let the system decide them, and leave them pretty loose. This might let you get to 3000mhz. Then you can go backwards from there, and adjust timings (first noting the settings on auto - by looking at the spd tab in CPUz) and then manually setting those timings in the bios, by dropping back a level. So lets say your timings at auto, and with 1.35v is 17-19-19-35-65 or something and they function at the desired speed. Then change the timings to 16-18-28-34-65. This is time consuming, but by doing so, and getting close to rated timings you will increase the bandwidth of the DIMMS, and the cas latency which can give further improvements. I hope i've explained myself well. The overall point being, with those DIMMS, you're gonna have to tinker around with these settings to get best results. Just remember to test all the way so you know whatever setting you change works. And only change one setting at a time. If you have any questions, drop me a PM, and I can try illustrate it better.

[@savianc9668]

for intel platforms, many articles show that around 3000mhz to 3600mhz is best performance. Once it goes above 3600 the diminishing returns pretty much hit the wall.

I "upgraded" from ddr3 1866 7-8-7-18 to ddr3 2400 cas11-13-13-38(xmp), dropped 20+ points in CB15 lol. Left it at 2133 9-11-10-26 and still was about -5 points. I did swap the old ram back in to double check and got about a 0.5% variance. Tried different banks and even swapping the slots for the same kits.

[@michaeltessitore8202]

I would love to find a video that talks about how to really tinker with the RAM and aggressive memory timings. You can find things online, but I would much rather watch a video that says start with these fields first, than move on to X, Y, Z. Here is the ranges most like to hit on average and it's safe up to this point. Giving the best parameters to tweak for the best performance so if something is unstable you know what voltages, timings, or whatever you would want to sacrifice first. Hint Hint

[@RodFitzpatrick]

Even a 3200mhz CL14 or CL15 kit is a great performer. For daily usage timings it's awesome and even with some small tweaks (say 3600mhz CL13 ) will still be very stable, with still lots of headroom to push it much further.

[@vidiveniviciDCLXVI]

Surely this memory though could run at lower freq and you could get some super nice timings on them?

[@scott2100]

I wish more testing would be done my memory vendors; with 3008 on a Crosshair VI Hero, I 24/7 hit 3200mhz at 14-15-16-35-50 with a F4-3200C16D-16GTZ kit, G.Skill would not stand behind anything over 2133mhz with the memory kit with earlier bios (where I was stuck at 2666mhz) where if I loosen up timing a smidge I'm stable at 3333mhz. In the end of my RAM adventure, the sub timings matter the most; the tRC 50 latency gives more response and snap to my system alone than going to 3.2ghz at the craptastic tRC 70 default but this is probably just a Ryzen thing

[@Cafe_TTV]

4700 CL19 is actually pretty impressive. I was expecting it to be 4700CL25 or something.

I have seen people that have managed 4200 CL16 on their 4400 cl19 trident Z kits. obviously on the high end motherboards for 8700k or 9900k.

[@GhostMotley]

Corsair is honestly a rip-off for memory, £469 for a 16GB 4500MHz kit, you can get the 8pack TeamGroup 4500MHz 16GB kit from OCUK for £389. Both the same Samsung ICs... While I don't recommend anyone buy this high frequency memory, shows what a rip-off Corsair stuff truly is compared to other brands.

So you should do testing with ram and ryzens infinity fabric. When you start to see diminishing returns and how much it actually does/doesn't effect performance.

[@juliaus]

Check out Mindblanktech, he put out a couple vids tuning up memory on ryzen and intel showing performance gains in a couple games

Mindblank Tech is the reason I can't consider Ryzen/Intel comparative benchmarks from other techtubers as 100% accurate.

[@nuyabiss]

bobsagget823 would also point out that most of the test didn't point out how much it still depends on your gpu to even make a difference. Anything below a 1070/Vega you won't notice the same boost that you do with them. So Jo they haven't done a diminishing returns test, because they're hitting the cap on the processor for memory not when diminishing returns starts to become a factor.

@ActuallyHardcoreOverclocking. When you tighten the timings, what kind a thinking you do in your mind there.

To me those. ^Ras to cas" is just bunch of mumbo jumbo. How do you do the thinking when tightening timings? A idea for video.

[@DustyOrchid057]

3600 MHz is plenty for ram, I doubt you would see any differences if you went higher

[@CampyCamper]

If you could get a kit like say a 4133 CL17 kit from G.Skill for realatively cheap, couldn't it be a good idea for a top gaming Z370 system, where you could drop some of the clock speed and instead focus on getting very low latency? What do you think is the highest freq/voltage and lowest latency one should aim for in terms of settings for stability over several years? Is there any point in trying to go for say, 3866 CL15(or lower) or is that unreasonable? Or alternatively 3200 CL12? Which memory kits do you think would be the most successful for running very low latency for a long time?

[@ryanbernard6550]

Great video really I started watching your channel like a month ago and already it's one of my favourites

[@NavJack27gaming]

what do you think about the realtime memory timing thing that some Intel platforms allow? since most of those are subtimings and you could get a more instant feedback on what changes do what, would it be worth it to mess with that to get a rough quick feel for for the timings before you commit to a bios level change?

[@ActuallyHardcoreOverclocking]

The few times I've played with the utilities for that they had a tendency to crash settings that would work from the BIOS.

[@2ndLastJedi]

Sorry to spam your comments ! But does that QVL just mean that those Mobo's will sort of guarantee that speed ? So if i got some 3000MHz for my z170 Extreme 4 that aren't listed as QVL it means that i may not get that speed and just do 2133 or does it mean it wont post at all ?

[@XX-121]

the vengance LPX series have SHITTY sub timings. just so you know. that's a bigger problems for people with pre-built systems that can't adjust OC settings.

[@philipp594]

I blame Jedec. If they standardized higher speeds. The CPU memory controllers would be better and the Dram OEMs couldn’t just set any random timings.

[@blazingmatty123]

see these kinda things were useful back in the X58 days because then you'd never be limited by your ram speed, i wish i'd gotten 2000MHz kits back in my X58 days for that reason :P my ram was my limiter then, my X5650 would go to silly levels but the ram was holding me back, nowadays though these kinda things are silly

Ryzen doesn't support anything higher than 3600mhz. And even at about 3200mhz you start having memory compatibility issues.

[@BioToxin]

no discussion though of ryzen, which to some extent can benefit from a higher ram clock, though in my experience the edge of that benefit is before 4000, that said a reputable manufacturer like gskill and corsair I've bought the cheapest kits of a given line they have and run them at basically the same settings of several other sets easily, my best case was a dominator platinum I got at the bottom that I pushed right up to the top and then still beat timings. It still comes back to use case though, what are you doing with the ram and in most cases better timings usually is the answer.

ive seen alot of people who built ryzen systems but they dont get the actual xmp profile clock but it is usually always lower even tho its like months after so could that be related to the memory controller even tho the manufactor's website says it is support?? and im specifically talking about around 3000-3200mhz

[@66racer]

Am I wrong to wonder the point if actual latency on that g.skill kit is about 8.08ns but a 3200mhz cl14 would be about 8.75ns? Is my logic flawed to think in real world work loads they would be similar in performance?

[@kozad86]

Doesn't the DDR4 spec top out at 2666 anyway? Anything beyond the specs will be non-standard, so there's no real guarantee that they'll work on any given system, or ever operate at advertised speed. Myself, I look at CL timings along with speed.

[@willjohnsonjohnson]

You should write down and organize everything you want to discuss long before recording. Your videos start out great laying everything out, but by the end you're beating a 3rd dead horse and just remembered there's still a live one in the barn. For PCB breakdowns, you should predraw everything to save time recording. Cutting down the video length and less rambling would greatly increase your number of viewers. One thing to improve this video. Instead of showing the memory manufacturers websites, you could have had the kits specs written down in a spread sheet and displayed that. It would cut out all the time wasted browsing their sites. You skipped over a few decent kits to use as examples of better performing memory which added on a few minutes. I love your videos regardless. Lots of information that can hard to find, especially the PCB breakdowns.

Hey Buildzoid. Ive been trying to get my Ryzen system to handle higher memory clocks (currently stuck at 3000) and Im having issues with my GSkill kit. While there are timing tables for certain speeds, there arent any for speeds from say 2800-3400 (just the non-XMP profiles for 2600 and lower along with the XMP profile for 3600), so I have nowhere to start from for all the sub-timings except for tables that are obviously not for the speeds Im going for. I would really appreciate if you had any ideas or places to go to get some ideas for where to start with those.

THX for the info, hope you cover high frequency DDR4 on X470

Question. Is having 32Gb of ram the same if you have two 16gb sticks, or if you have four 8gb sticks of the same brand name/latency ect?

[@arnold3811]

Do you have a guide for Intel based tuning? Z170/Z270/Z370 based?

[@elesinalex]

Hi buildzoid, can you address xmp memory ratings in ns? They can be found in the thaiphoon burner, under report + "show latencies in ns" button. Seems like the best kit considering that parameter is the 3600C15 kit from gskill. Are those latencies are a good way to check actual memory quality?

[@ujiltromm7358]

The latency rating is given in "clock cycles required to complete a given command", and the tighter the timings for a given frequency, the better performance of the chip. For instance, if a clock cycle takes 0.3125ns to complete (3200MHz) and the latency is 16 clock cycles (C16), that makes it a latency of 16*0.3125 = 5ns. If you get your RAM from that to say, 3200C14, you end up with 14*0.3125 = 4.375ns. That seems kind of underwhelming, but that's still a reduction of response time down 12.5% from the original timings. They are in ns (0.000000001s), and add up really fast when seconds are considered. Mindblank Tech got his 3600C16 kit to run at 3466C14 (as well as tweaking various other timings) on his Ryzen system and got a boost in performance compared to 3600C16. The 3600MHz frequency was basically useless since the workload wasn't requiring that much speed (bandwidth), making faster response time by way of tighter timings better suited.

Could you do a motherboard/socket insulation guide for LN2?

[@mihaimladin5054]

got a binned ram kit that can do 4200 17 18 18 for daily with 1.25/1.3 io/sa. cpu is watercooled. is it safe for longterm?

Hey Buildzoid , how does memory speed affect VR performance ? I was silly and built my PC with 2x4GB 2400MHz and couldn't find anymore RAM the same so just bought cheap 1x8GB 2133 and OC'd it to 2400 so now have 3 DIMMS in a z170 extreme 4 with 6600k and a 1080Ti . Am i just loosing performance by having 3 DIMMS and would i be better off just using the 2 x 4GB @2400MHz ?

[@alynicholls3230]

maybe as you are not getting multi channel, i have an old rig used for running SDR, its an Athlon 64 3000 with 2 gigs of dual channel ddr1(2x1gig), i have 4 sticks and wanted 4gb dual channel but the board in the machine ignores the 4th slot, it is seen in bios and win 7 64bit, but unused so you really only have 3gb single channel, now you would think 1 gb more would be better for the machine even single channel but i found 2gb running dual channel was a better setup than 3gb single. so in your case you might be better selling that 8gb stick and getting 2 4gb sticks so you get multi channel then just play around with memory settings till you find a setup that all sticks run at comfortably.

[@parasecglenkwyst4835]

So tell us how to tune our RAM properly :). Tho I guess on Intel it's mostly the same as told in your Ryzen RAM OC Guide?

[@ActuallyHardcoreOverclocking]

it's similar though Intel is a lot more flexible and there's a lot more settings.

[@delta9k]

Thanks Buildzoid, nicely done!

[@yakacm]

My 16 Gb vengeance kit is a bit sniffy about booting my i9 9900k and Asus Maximum Hero XI and it's only 3600, it just laughs at me if I try and increase the speed even by 200 mhz, the hilarious thing is I used to have a 32Gb kit of vengeance 3000 Mhz which would I could run at 3400Mhz no problem, I bought the 3600 assuming I would be able to run it at 4000Mhz no problem, was I ever wrong?

[@ODIOPOWER]

Can you do a video on how to set timings and explain what they do?

[@AdaaDK]

How manny different binning Samsung B dies exists ?.. i seem to have a pretty badly binned Corsair 3600C18 kitt, they wont even seem to do 3200/C14 at very least not on Ryzen, i still need to test them proberly on my I7 8700k.

[@ActuallyHardcoreOverclocking]

The bins depend on manufacturers. Corsair from what I've been told by others seem to bin really hard and so any kits with "average" settings like 3600 C18 from them are pretty much guaranteed to be bottom of the barrel ICs while the really expensive kits tend to be much better. With G.skill I think it's all about going for kits with tight timings. So 3600 C15 or the new 4000 C17 For example G.skill 3200 C14 and 4133 C19 weren't know for being great and the early RGB G.skills are apparently terrible because they screwed up the PCB. Teamgroup I have no idea all my kits are 3733 18-20-20-39 but Team have told me that they hand bin the kits I get sent so mine probably aren't representative of the average 3733 C18 Team kit.
