Hi Buildzoid, the reason your Aida latency benchmark is inconsistent is because windows is still doing things in the background after rebooting. Run it in safemode and it’s super consistent.

[@gameison4813]

i tried it in safe mode and it was very consistent. It was ranging from 0.1ns higher some times and 0.1 ns lower but very close and latency was slightly lower as well

[@t7274]

Yes but that's not a realistic test because you aren't going to be using your PC in safe mode.

[@IIHydraII]

@@t7274 The point is you're comparing differences between tuned and untuned memory. Of course you want to remove as many variables as possible...

[@jacob4816]

Yo for anyone that has the gskill trident z5 6400 CL32 kit, I saw a lot of you saying that these timings are unstable... I have this kit and can run these timings 100% stable @ 6400mhz with the 1.4v's exactly like he has it in the video. If you are unable to boot, its probably because you set a subtiming wrong. They are not in the same order on my MOBO as they are in this video, its easy to set the wrong thing. Lastly, if you get errors running a memtest, or large ffts on prime95, its probably due to your cache OC, or CPU OC. disable your CPU OC's, then adjust ram, test for stability, then do your CPU OCing. If you do get errors, to check if its the ram or CPU, you could also lower the ram MHZ to something really low, retest and if you still get the error than its caused by your CPU overclock. edit: For reference -13700k (stock) - ASUS z790 prime-A - Trident z5 6400mhz 32, 39, 39, 102 @ 1.4v ; tuned to 6400mhz 32, 39, 39, 28 | Command rate: 2T

[@Vegemeister1]

I notice that you increased the refresh interval by more than 10X, and I've seen you do similar things in other videos. It seems unlikely to me that DRAM designers are overestimating the refresh requirements by such a large margin, especially since refresh has substantial power cost. How sure are we that regular memory stress tests are creating the kind of conditions that are most difficult for data retention?

[@bananya6020]

Warning, I don't really overclock memory for a living or anything. I heard that the main reason is that of course the memory has to meet some kind of spec and usually that spec involves being in some extreme (for us) temperatures. As in, like 40-50°C ambient temps and such. However, for homes usually it's 23-27°C which I think would decrease power leakage (since lower ambient temps = lower RAM temps = less leakage) and therefore you don't need to recharge it as often. Idk about the tests being a good estimator of memory though but in my experience you could basically always crank the tREFI really high unless you're super concerned about your data

[@dabneyoffermein595]

overclocking the 12900K is a PITA on ASUS AiOC, total inconsistent results with my G-Skill Trident 16x2 ddr5 6000 36-36-36-72 at XPM I profile and AiOC CPU overclocking enabled with an 89 value on the Predictive setting (which is supposed to dial down expectations). I get up to 5200 to 5400 speed but voltage spikes are ridiculous at 1.43v (idle) to 1.49v and sometimes higher when gaming or doing stress or benchies. So crashes occur while gaming if both are set (XMP & OC). It's hard to overclock anymore, it's a real shame that Intel can't build these 12900's to crank out at least a single-core of 5.5 or so. I mean, yea, i would get a 13900K and slap it on the z690 mobo, but I'm paying $550 for 500Mhz and what am I going to get, like 2 to 3 more FPS at the most? Probably yea. I listen to Buildzoid because in his 13900K video he spells out how ridiculous it is anymore to get these chips to OC at worthwhile values and heat. The average gamer has an AIO cooler on their CPU not a custom water block, which doubles the cost of gaming (EK water block). I realize my RAM is friggin' junk (G-skill are Samsung memory chips) after spending a fortune on the ram early in the game. What a tragedy of events as I ho-hum my way through the tulip patch at 4900.

Made a huge difference too! I was getting terrible latency times in AIDA64. Still not quite as good as Buildzoid's in this video, but from 76 to 57ns @6200mts cl32,38,38,28. Probably can eek out a bit more but I'm good for now 👍 and yeah I know, the RAM was definitely an overkill/non-economical choice considering the other combined gear but I really didn't know what I was doing when I bought all this stuff and thought one day, I could throw in another similar 2x24gb kit when cheaper for 96gb total RAM... but after watching/learning from a couple of Buildzoid's videos, it will probably perform terribly, if at all. 😢Not sure if its worth returning though. any maybe TMI but just wanted to thank you.

[@vagetaqtd]

FYI. Turn on Memory Context to retrain your memory if you are overclocking any memory timings. My PC 7950x / Asus B650E and 64gb DDR6000 CL30-38-38-96 along with Buildroid's custom timings would instantly BSOD on boot or wake from sleep/hibernation. After renabling Memory context to retrain before boot, BSOD stops and system loads normally.

[@RavTokomi]

I had to translate to MSI BIOS, but these settings were a solid improvement for my GSkill (Hynix) 6000/30 kit. It ran these advanced settings at 6000 CL30 at stock 1.35v. Only thing is the latency at lower inject delay seems poor in Intel MLC, over 100ns, compared to 50s at the high end. That spread seems high compared to some tests you have shown (70s low to 50s high). Which settings affect that most if I study the more advanced guides?

[@4gbmeans4gb61]

If windows or any program is doing anything in back ground when you run the tests, the ns benchmark will be all over the place. Restart in safemode and try the memory tests to get consistent data.

[@jacob4816]

@@housebaelishgaming did you figure it out? Your mobo might not be able to handle the 6000 speed, but it most likely should (if it’s a decent z690). What I would do is f5 default your settings, and manually set your ram to 4800mhz, also set your DRAM voltage to what’s listed for the kit you bought (most likely 1.35v or 1.4v). Assuming your kit is the trident z5 6000mhz CL30 kit, enter all the ram timings as he has it. Then boot and if it does boot, restart your PC, raise the ram MHZ by 200 (no need to change the voltage again at this point unless it’s unstable), and if it boots raise by another 200mhz. Keep repeating this in steps of 200mhz, until you reach the 6000mhz. Sometimes if you set the mhz too high at first it won’t boot due to memory training and the motherboard not being built well for DDR5, but you can achieve the speed by letting the memory get trained and only taking it up in steps of 200mhz. Hope this helps.

Hi Buildzoid, I am considering buying a mining 6900XT for $550, is it safe & good deal? thanks

[@PwadigytheOddity]

Yes. Mining is better than gaming. No thermal cycling. What degrades the core isn't primarily how much work your card does, but rather what kind and how consistent. Miners don't push the core, and they underclock and undervolt them as low as their cards allow. Then they run them at the same temperature constantly. What causes damage is when the card boost really high and gets hot. And when you're gaming, your card is literally designed to push itself as much as possible. Plus miners take care of their hardware, because the wholepoint of GPU mining is to keep the cards in good condition for resale. You could say "oh, miners run their cards into the dirt and pass them onto you." Except that's not the case. Miners wouldn't risk pushing their cards or degrading them because if they have 20 cards that are poorly maintained, then they'll probably have one fail before they ROI. The difference between a well-kept card and a gaming card from someone who slots and forgets is miles. Definitely get your hands on a mining card. Just ask them to show videos of it running in a PC and checking benchmarks of furmark and HWinfo to make sure nothing is weird. I've gotten many good cards for me and my friends this way. The only time I ever got a card that died right away was a 980ti from a gamer. I always buy used mining cards at good prices.

the timings in this video should work on any motherboard as long as you have Hynix DIMMs and aren't pushing north of 7000Mbps. IDK if they work above 7000mbps because I can't do speeds that high on any of my boards.

[@davidrev2489]

Is this copy settings also work at my system? CL 6000 hynix a die Asus z690-a prime 13600kf Or should i change some settings ?

Hello, I have an Asus b660a gaming edge 6000mhz(O.C) wifi ddr5 motherboard and when I open gskill 2x16 32 gb cl36 ram 6000 mhz xmp 3.0, I get a blue screen error. I have no problems in games, especially at 5800 mhz. I can run it at 5800 mhz when xmp is not turned on. ?

[@barnold62]

Will these work with the ROG Maximus Hero z790 and Corsair Dominator DDR5 6400? XMP makes this memory unstable.

[@YTaccount11454]

cant get these to post at 8000 when changing the timings and voltage from xmp tweaked, using 2x24gb gskill kit, its fully stable at 8000 xmp tweaked. the only main difference and potential issue i saw is that i cannot set the timing DRAM REF Cycle time , its grayed out, while i can set DRAM REF Cycle Time 2, which is what i did... but like i said it wont even post.

Hi BZ, so , I know this video is a year old, but I'm running an Asus motherboard B650M-A AX II with DDR5-6000Mhz RAM and a Ryzen 7 7800X3D chip and its crashing my games, when I underclock the RAM to 5200Mhz it runs fine.... I updated the BIOS on the Asus Board, but still crashes. Any ideas what could be causing this or how to fix it? thanks

[@mtt712]

So is it okay to (try) to these subtimings on other D5 kits on ASUS so long they’re sk hynix? Say I use adata 6000 kits

[@sabishiihito]

Yep, seems the main difference between Hynix-based sticks is how high they will clock

[@abdulsalamshar5601]

i have 2x32gb crosair hynix that is 6200mt cl32 32 38 38 80 running on 1.4v, when enable xmp the pc train memory & work fine, but when start gaming i get crashing & sometimes pc restarts, then i run stability test for memory on OCCT i get many errors, how can i make it stable on my system whithout me redusing the ram speed? i have 12900k on gigabyte aorus ultra z690 motherboard

How possible it’s to get an appointment, Im stuck with ddr5 6400 tried your times and it won’t boot at all.

[@ak3d1]

Hello i wanted to say that i have an i7 12700 k + mb same as u+g.skill 6400 trident. I did the exact value from your video and i get only 100 point more on 3dmark. Then i set the first timing at 30 37 37 and i got an improvement of 1000 Point on 3dmark. As for the latence in ns i got first time by defaut xmp 62.10 then with your setup 59 then with the changing of first timing 56. I dont know if i can improve it ??? Tx your for all your work it s very usefull.

[@XoxJasonReynoldsxoX]

So you kind of need your Asus board to even boot with either of the xmp profiles? Still waiting for the bios update for my prime z-690 that allows either xmp profile to boot my fury beast ddr5. Go Asus!!!

[@sublimesupra]

I absolutely don't wanna know whats those timmings are, but is it safe for everyday gamming or actually for hardcore overlocking?

[@James-zk3yu]

To confirm, will these kits work on the Apex z690? I don't see them listed on the QVL, so just want to be sure before I hit buy. (totally new to overclocking)

[@ActuallyHardcoreOverclocking]

There should be some SK Hynix based kits QVLed for the Apex.

thanks for the video i try this setings on my ASUS Z690 HERO 13900K g skil 2X16GB 6400MHZ IT WORKS GREAT

[@blai5e730]

Thanks for the video Buildzoid, the link you provided to ROG's Mem TweakIt is the first version I've managed to successfully launch on my Z690 Hero board! I'll definitely be trying your setting out today as I have the Dominator Platinum RGB 6200's which I believe are also SK Hynix M-Die. A question... is it possible to get 1T timings working with DDR5? I've had zero success with either DDR5 4800 or 6200 kits.

[@ActuallyHardcoreOverclocking]

1T depends on the motherboard.

Whats the impact of cpu input voltage? Can I leave it auto?

[@ActuallyHardcoreOverclocking]

raising can help stabilizing RAM overclocks as it's the voltage that's used to generate VCCSA and CPU VDDQ

Great Guide for DDR5 improvement 👌but my ASUS ROG Strix B660 G-Gaming dont work with the MemTweakIt link. In BIOS is Realtime Memory Timing enabled. Can you help me?

[@wezke4115]

@Buildzoid, im running a kit of kingston fury beast ddr5 6000mhz cas40 that absolutelyn wont run these settings. Infact nothing i try with them seems to run, i think this hynix kit is pushed at its limit allready unless my board (asus z690 Gaming E) is preventing me somehow. I really wonder as i hear hynix should easely be able to do more than these.

[@S3rinox]

Got the same kit as you. Mine does 6000 30-36-36-28 with bullzoids subs @1.4v vdimm just fine. I think you might wan´t to check your memory controller voltage. I set mine to 1.246 volts. My mobo is a b660strix-f.

[@squirrel6687]

Same here. It will not boot. I'm thinking maybe memory training is occurring. The fans are ablaze at 100%. I changed the SA back to Auto and got the same. How long should memory training take? How did you achieve those timings?

[@jeffwidjaiwdjawd2331]

i updated my bios to v2703 (latest), i set my XMP 1 on, then started crashing in all games. few days later i set my XMP to disabled, set everything default, rebooted to windows, it ran fine. went back into bios to re-enable XMP to 6000mhz like before at XMP 1 and it now works. weird. z690 tuf gaming plus wifi, hyperx 2x8gb 6000mhz xmp ram. also, is it normal for the PC to restart several times with an orange light, then run fine after a few restarts & load into windows properly on when i enable XMP to 1?

I can only get down to 63ns (59 on a lucky run) with these exact settings with my hyperx fury 6000c40 (set to 6200c36 as in the video). I'm only on a 12700k with b660 board but you'd think identical memory settings would be close.

[@vavalexus]

Hello! Got Mobo Asus Rox Strix z690 DDR5, CPU 13900KF, RTX 4090. Some time ago I had DDR5 Corsair Vengence 5600. Somehow it worked with XMP at 6000, but the results was much worse. Before I saw the video I lived the noral life )) So with Corsair 5600 32Gb (2x16) it is R-50000, W-44700, C-48000, L-72. But when put my new DDR5 Kingston Fury Beast 6000 64Gb (2x32), it never sucessfully loads up with XMP I - always comes up with the BSOD. It only boots normaly with the XMP set to 5600. And the results are surely even worse - R-45000, W-39000, C-44400, L-82. Any advice?

Asus Z790F, TEAMGROUP T-Force Delta RGB DDR5 Ram 32GB (2x16GB) 7200MHz PC5-57600 CL34 A-DIE, Intel 13700K. Single RAM stick in A2 or B2 runs XMPII at 7200 fine, memetests no errors. Both RAM sticks single are fine. When I use 2 sticks in A2 and B2 (dual channel) the whole thing is unstable no matter what. BSODs, corrupt apps crashing, total nightmare, even stock settings at 5600.

[@Sprinkles-BtE]

I'm currently experimenting with this videos setting with my new Mobo/CPU config I just purchased. I7-12700k, Asus Z790-PLUS WIFI and a pair of Single Rank Teamgroup T-create 48GB (2x24gb) 7200MTs M-DIE CL34-42-42-84 1.4v I'm not able to POST with XMP1 but am able to with XMP2. But I can't get into windows without crashing unless I clock it down to 7000... but it's still not stable in games or tests like OCCT or Memtest86. It has to clock it all the way down to 6200 to get to truly be stable. 😢

[@WickedCrispy]

I ended up reverting to stock XMP2 because his settings wouldn't POST on my board. Memtest gave errors until I lowered the speed to 7000. Good enough for me, so that's what I'm going with. @@Sprinkles-BtE

[@Sprinkles-BtE]

@@WickedCrispy I actually got Buildzoid's settings to work dude! Well, almost all of his settings. But it made a huge difference! Follow the advice that IIHydraII gave on ejosephsimon's comment thread in here. Basically, you can do everything Buildzoid did but you probably just have to loosen a few key timings to get it to work. I basically had to set the Secondary Timings of DRAM RAS# to RAS# Delay "L" to 8, and the "S" to 6, along with DRAM REF Cycle Time 2 to 500 and DRAM Refresh Time Same Bank to 400. Not only am I able to POST and boot windows, I've done four '1 hour' passes of OCCT AVX memory test (the AVX version seems to be more sensitive in my experience) and four '3 hour' long Memtest86 test, all passed with no errors! I later revisited those same settings just to see how much tighter they can be. I was able to get DRAM RAS# to RAS# Delay "L" to 7 and the "S" to 5 (any lower and no POST) and I was able to further reduce DRAM REF Cycle Time 2 to 475 (450 and no POST) and DRAM Refresh Time Same Bank to 325 - I tried 300 and it actually POST but my system was weirdly unstable - it would lock up randomly while trying to enter the BIOS or shortly after getting back in! This was a pretty scary position to be in because it's just at the cusp of failure. The BIOS is believing the setting is fine and not booting to "safe mode", but it would hardly give you long enough to go back and change it to a looser setting before locking up again! But thankfully, with some quick hands, I was able to make it back to that setting, loosen it up to 325, save and reboot! And now... Well now, it's golden! But to be honest, even getting these timings *that* close to the razor's edge didn't change that much in the benchmarks over the settings I initially told you (ever so slightly worse read, but slightly faster write and copy - about the same latency - kind of a wash unless write is more important 🤷‍♂). So it may not worth all the trouble to fine tune it *that* close. Despite my RAM sticks being of the same maker and same speed, obviously there's enough difference that my exact setting might not work (2x24gb and M-die after all) but you should at least give it another try... just try loosening up those 4 settings over what Buildzoid outlined before giving up. You're leaving a lot of performance on the table. Overall, it reduced my latency in AIDA from 76 to 57 and helped the throughput of ADIA read, write and copy by ~10+ gigs per second at only 6200mt/s (the max my 12gen cpu/mobo combo seems to be able to handle, in seems)! Makes me feel a little better about my not-so-great buying decision. Many thanks to you, Buildzoid, if you bother to read these things. 🙂You really changed how I look at RAM and the marketing of them. I wish I had discovered his channel sooner. Especially before buying my recent PC upgrades.
