A friend of mine has both the Z690 and Z790 and was wasting his time trying to reduce to tCL to 32, bring foolishly fixated on his primary timings, meanwhile completely neglecting his subtimings on Auto. I told him he's fiddling with poop! Tuned his subtimings similar to yours and he was shocked his Geekbench score went up by 2k points. I think a lot of people are stuck with the DDR4 mind set where going from CL15 to CL14 has some impact, and gong from CL14 to CL13 is some exotic rare overclock. More people need to watch Buildzoid's video on tCL speed doesn't matter on DDR5.
I bought this kit because you recommended it. Couldn't get it to overclock with stability. Tried some suggestions in your video and a quick test at 6800 and 56ns latency seems good. Thanks for spreading your knowledge.
@@BBWahoo I have the Kingston 6400Cl32 M-Die at 6800Cl28 on ROG z690-f with 13700k and i am hitting around 50ns in Aida with timings tuned to the absolut minimum values and 4.9Ghz Cach/Ring. 1.56v VDD / 1.50v VDDQ / 1.38v VDDQ TX and 1.365v IMC. Pretty happy about that!
@@Schlappenschleuder Really!? Those are amazing timings!!! I think that's the lowest latency I've EVER heard reported on a DDR5 kit!! I bet PrimoCache would be GODLY on that kit, the fact it's itching already beaten Zen 2/3 timings and is closer and closer to reaching 10,000mt/s has me super hyped! I just hope Arrow Lake has AVX-512 support, then next gen will have the 4790k of the DDR5 generation. Man. I AM PUMPED!
@@BBWahoo Sorry for the late answer. People are getting even better latency results but with way more frequency around the 8000 range. People also say the i7 also gets better latency then the i9 due to the shorter Cache. Still running it like that and i think this will be rock solid long lasting. I am also curios what comes next, thery interesting! :)
BZ You are the man! You have no idea how tremendously this video helped me! My MSI Z790 Tomahawks can only do 6800 y-cruncher VST, but I was wasting my time bottoming the timings, running low subtimings on 6800c32 that required the DIMMs to be under 48c to pass, eh screw that. Eh well screw that! I'm now running CL34 with exactly the same subtimings as used in this video, besides tRFC/tREFI that I loosened up a bit, and now I can pass 24hours+ of HCI *without a fan* over the RAM! It reaches 62-63c stress testing but still passes, bloody awesome. I'll check later if I can also pass with tRFC 333 and tREFI 50000 as well since I have an M-Die kit.
thanks to this tutorial videos i manage to work brand new computer with gigabyte Z790 gaming X and 13600KF. cpu no problem but memory kit Kingston renegade 6400 cl32 xmp was nightmare. latest bios. but stock settings and xmp enabled ended in bootloop. then i set vccsa 1.35V , later lowered to 1.3V and mirracles happens..all work. later i set 1T . works for weeks now. no other Voltage adjusted . even 13600K goes to 5.2 and 4.1 with bios max.perf setting. i tried manual 5,4 and 4.2, no voltage adjusted, works perfect. big thanks to this tutorials and clear explain. p.s. my mem score in some memtest is 97gigs, cant go over 100... not verry happy but it is as it is , and latency is 70ns... i think little bit higher than usual...
My friend, thank you for sharing everytime If i can suggest to you a simple command, with cmd or a shortcut or a bat shutdown /r /fw /f /t 0 This will reboot itself in UEFI Bios if is supported without smashing any key xD Greetings from Italy ❤
On Windows 10 TM5 gets put into e cores and it actually skips tests for some reason and casues it to report errors in the "idle" period between cycles and makes it completely unreliable.
Same goes for example for cinebench r20. When put to "above normal" priority or any higher it uses the p-cores too. My cinebench was below normal priority by default.
I see that as of a couple of weeks ago, Kingston sells 5600 and 6000 mt/s 2x16GB kits with CL40 timing in the US. Is it a safe bet that they're still Hynix? If so it's probably the cheapest new option so far at under US$90 at newegg for the 5600 kit
Both of them can apparently even be Samsung, even though Kingston doesn't usually use them in 5600 and 6000 kits. And I heard some people have also received Micron on the 5600 CL40 one, so not worth risking imo even if the CL36 kits are a bit more expensive.
@@atirta777it's worth it if you can purchase in perform but not online. If you purchase in person you can look at the kit and it says the IC type on the label.
@ActuallyHardcoreOverclocking, I loved your video, very informative. I followed it to the T and got no errors when testing but after about a month or so some games randomly crashed while gaming, while others didn't. Going back to the XMP profile 1 at 6000Mhz seems to have fixed the crashing issue so it was probably memory related. I didn't clock it at 7200 like you, but 6800Mhz, maybe im unlucky or did something wrong. What kind of settings would you recommend for the same type of kingston memory, just cl40 instead of cl36? intel 13600k, MSI pro z790-A wifi, KF560C40BBK2-32. Thanks a lot
The PLL voltages are a life saver, they work! I have MSI Z790 Tomahawk paired with 5600c46 (A-Die) and I simply couldn't get y-cruncher VST stable last 6800MT/s, it would within the minute or two. I used the same CPU, RING, SA & MC PLL voltages and I'm now stable half an hour and still going on 7000MT/s running y-cruncher VST. How do people manage the find PLL voltages, is it simply trial and error each time? I will try 7200 next up and update.
Stable is such a relative term on an OC like this. Sure it might be stable your on MOBO/system, might not be on another. Might look stable to you but crash out everytime at very specific work load that you haven't tested. Sounds cool though! Wish AMD could get their memory controller act together.
@@Dave-kh6tx I am aware, thank you. It still doesn't negate the fact that AMD has work to do on it's memory controller compared to intel. I have personal experience with both platforms and infinity fabric on am4 and the new controller are both finicky AF and fickle. I am a full on AMD fan but it doesn't blind me to the issues at hand.
That's why he runs multiple different stress tests in a certain way as in his experience, which is vast, it gaurantees stability thereafter in any workload. This is why there's no singular test that guarantees stability. I've run 1000% hci memtest for example and crashed in 20 minutes of bf2042 because trefi was too high making the memory heat sensitive when gpu heat was added to the case.
I wish there were more guides for both DDR5 and DDR 4 on AMD for getting decent clock speeds with 4 double sided dual rank sticks. For example on my 5800x build, I can't get speeds above ddr4 3600 to boot. I ended up tightening timings at 3600 after even 3666 wouldn't boot.
You'd be extremely lucky to boot in synchronous mode above 3600 on Zen 3. The imc is basically limited to that speed (FCLK @ 1800). Some will do 3733 but above that the fabric will top out and then you'd face a latency/performance penalty running asynchronously anyway. This has almost always been the case for DDR4 on Ryzen. For much the same reason Zen4 DDR5 also has a lower ceiling for the imc compared to Intel. That's the whole reason he's running Intel for these 6000MT/s and greater speeds.
hey BZ I changed my mobo from z790 Aorus master to an MSI Ace z790, I used to run tighter timings with the gigabyte board that arent working on the ACE, you think is mobo quality or voltage differences? thanks!
Hey buildzoid. I have an issue trying to stabilize 7200 on a 4dimmer. Basically i can get it to work but as soon as i re-enable ecores VT3 doesn't work anymore. Any clue?
Any suggestions for the asus maximus hero with i9 12900k and 4x16 ram ddr 5 6000mhz kingston fury? i tested all the settings of all your videos and it can't post or if it does post then i get the blue screen on windows... thanks.
The z790 Asus motherboards have the lga1200 mounting holes for the cooler and the lga1700 also, is there any difference (in terms of mounting pressure stability) if i use the lga1200 bracket instead of the lga1700?
Greetings. I have the b760m pro asrock, i5-13500, ddr5 7200 TEAM group kit, but it is not stable at 7200, so I chose to place them manually at 6000 but with cas 30 at 1.35volt. Is this conf valid?
Graet video, really explains alot! Would like any help i can get with 2x32gb g.skill hynix m-die 6400 32-39-39-102 kit on a msi tomahawk with 13900ks. What values i need to change from your setup to make it run at 7200?

@Actually Hardcore Overclocking but if I already have some that is at 4000c16-17-17-32 with tuned getting 62gbs and 48ns is it worth upgrading on a 13600k z690 A Pro. That's is why I ask. Dual rank 2x16.
I would love to have your Insight on the new corsair vengeance 4x16gb 6600mhz 32-39-39-76. I just got them in the day before yesterday and it says they were made in week 14 of 2023, literally last week but xmp doesn't work I got it to run at 6600 MHz by loosening Cas latency to 34 and adding .01 voltage and I was able to pass memtest 86 but with them being an actual 4 dimm kit I expected xmp not to give me any problems I have a 13900k on a MSI z690 carbon also for some reason my motherboard defaults two quad rank even if I only have two sticks in idk why or how to change my motherboard isn't even supposed to be capable
Intel has hard time with 4 sticks of ram. It's better to go with two sticks unless you need the ram. If you need the larger ram you should be willing to sacrifice speed and timings. Intel is also having harder time getting super speeds with 2x32gb also.
@@Dave-kh6tx its not an intel problem, its a mobo issues, but across the board, 4 is harder than 2 which is harder than 1. There is an ocean of people out there running fine with 4 sticks on AMd and Intel, but thats going to be rather edge vs 2 sticks on nearly anything, even the sh!ttiest mobo and cpu.
@@xBINARYGODx where is this ocean of people? I've seen a lot of threads where people have a hard time running 4 sticks. It's hard to run 4 sticks past 5600 for example. 4800/5200 have more success but not always. And not every every Ody has Asus Apex money to have a better chance of running sticks at higher speeds.
Can you do a detailed Bios settings video with the 790 Edge? I have the i9 13900ks, GeForce 4090 25GB GPU, Kingston Fury 5600 16x2, 1200 Thermaltake power, 360 Thermaltake water cooler, I'm having crashs at start up of Battlefield 4042 game. if I turn the CPU down to 5GHZ it runs fine and its stable.
@@HaloMediaRecords Hi, different board ( MSI z790 Tomahawk D5) different CPU (13700k non F 2x5.5 8x5.4 p cores 4.9 ring stock e cores, hyperthreading off) but I hope this helps u somehow. Had stability problems with my xmp kit (HyperX Renegade 6800mhz A die) auto voltages and everything, then watched the Aorus z790 7200mhz A die video he posted. Copy'd most of the timmings. Came to this to get a general idea of voltages since he said raising PLL voltages might fix it (remember, everything was set to auto), set everything manualy to around the same he showed (PLL voltages slightly higher to 1.05v)... still unstable (insta crash on Y cruncher 2.5b)... Then started lowering PLL voltages (CPU, Ring, MC, SA) (because I remember hearing him say some voltages can sweetspot for specific boards/board manofacturers, sometimes raising voltages could cause instability), that did the job, ended up landing @ around .95 in most of them. Also tried lowering CPU VDDQ, VDD2, SA; got SA to 1.2v and VDD2 to 1.3v (lowering even 30mv from those caused instability), no success on lowering VDDQ, still @ 1.4v. I hope that helps if u're still having problems, dont try to copy it straight up and hope it works but maybe the general idea helps u get it stable. I've been running it like this for the past 15 days and no crashes for my general use.
what about Kingston Fury 64GB (4X32) DDR5 6000 CL 36 memory in a (Z790-E Asus) so far work stable with 1.3v and 4800mhz but, Whats the point to buy a motherboard that in theory "support 128GB" but 6000Mhz is too much for T_T
from what ive read and seen 4 sticks are usually a pain to get to work on even mid range speeds above stock, and hell if you wanna get them to 6000+, its usually the overload from the bandwith to the memory controler.
@@cybyrd9615 Thank you I am new to ram overclocking I have Kingston Fury Beast RGB 6000mhz (Hynix A Die-)CL36 at 7000mhz 1.4v, 36-45-45-108, I have run MemTest64, for 20 loops with no errors, is this considered stable or should i stress test with something else?
@@zebbedy8113 technically any errors on any test isn't stable, people were saying to run y-cruncher 30 times, and Prime95 but I don't remember how many times. I don't have time for that
Too bad we can't do that on AM5. Infinity fabric? More like "Finite" fabric. 😂 Also I wonder, if AMD claims their next gen CPUs will be compatible with AM5 mobo, what's the point of that if AM5 already taps out at 6000MHz max?!
@@emini6 Yeah but any zen4 mobo you buy now wont have high frequency ram support. So how can you have high frequency ram when you replace zen4 CPU with zen5 in future on that same mobo?! Really disappointed at AMD for low ram and CPU frequency. But at least they have good gaming CPU now so will buy that. Not sure how low frequency will hold up in future though.

However me and bz always say silicon lottery does play a big roll and people should never judge a product on the first try without other examples to determine the averages.
AMD new architecture doesn't benefit as much from faster ram, especially x3d cache, because AMD's larger cache doesn't need to make as many calls to ram since the cache is much larger than Intel.
