Good thing i watched that video. I'm already happy with my oc but I'm always learning something new in your videos. This time why my system was unstable while idle, had bin trying so many suggested solutions already but this was the fix I've been searching for. Thank you! 23:12
After 3 weeks of pain with my new 7950X3D build because of terrible standard memory timings and voltages from my Mobo, it's now running stable at 6200 Mhz thanks to this video. Thanks for the help. I suspect the culprit was VDDIO and VDDQ voltages, but those run really well at 1.25v. I even managed to get the main VDD voltage down to 1.35v and it's still running stable. You're the best! Next step is tuning the PBO curves. At -24 on all cores at the moment, and from there i think i will do per-core tuning.
You can create a shortcut in the desktop and type "C:\Windows\System32\shutdown.exe /r /fw /f /t 0" in the location (no quotation marks). Computer will reboot straight to BIOS.
This sounds slightly better than the method I use, just copy/paste it from notepad to CMD prompt or powershell. It works great but think I'd prefer your suggestion. Thanks!
Hey man! Can you share your timings and voltages? I'm currently attempting to get A-die to 6200@CL28 and having no success :( 6000@CL28 works fine though!
I like this board. 1dpc, cheap, relatively good vrm-cooling. It will probably perform quite a bit better on next gens a few years from now when you can run memory at 8000+. Not sure if a lot if B650 2dpc can do that.
got the board, didnt like it because i need RGB LED connectors, got a B650M Pro RS for same price and it runs 4x16GB a-die at 6200C28 with 7700X, Asrock delivers.
@@UNDERGROUNDHITRADIO sounds good. Lack if rgb-header can be an issue for some, I build in a Lian Li case with rgb/fan-control-module so I had bo need fpr rgb-header :)
Got this board and the ryzen 7600, with Corsair 6000C36 but couldn't get it to work with Expo until I went from latest bios 1.24 to 1.21. Thanks for the video
I got it to run 6400 with SOC 1.3V and IF 2067, but I'm not comfortable with SOC at 1.3V for daily use, so I'l try 6200 with higher IF clock Edit: It's a Samsung B-die memory
At time of writing BIOS version was 1.21. I also had problems with expo with bios 1.24, but newer version were fine. Try updating to the latest, I think it is 1.30.
I think this board will outlive a lot of the 2dpc B650-boards if you upgrade to Zen 6+ when ram can run at 7-8000+. On Zen1 1dpc-boards after a lot of agesas proved superior on ram oc vs the usual t-top boards :)
The best setting I could do on my M-die that seems the be stable is 6000 28-38-36-64. Any further reduction to Cl, tRC and tRP makes it unstable / unbootable. Why tRAS 64? Well... I was trying to OC it while on the iGPU. At tRAS 30 I was getting video artifacts on idle. It would immediately go away as soon as I put any load on the CPU, but also would came back as soon as it got back to idle. Funny thing is it seems to be stable as long as its under load. Anyway I just followed a old tRAS starting recommendation Cl+tRP and the artifacts on idle disappeared. Didn't try pushing it down to see when the artifacts start appearing. I'm on a Ryzen 7 7700. I also couldn't make it stable at 6200. It runs for a while and suddenly start spiting a bunch of errors. I might try a little more another time but I don't have much hope left. 12:30 Yeah... I only get about ~63000 MB/s read and about 62 latency. Will probably get better results with a discrete GPU but I don't imagine it being that much better.
I overclocked a Hynix M-die (G.Skill Flare X5 2x16) to 5600MHz 28-36-36-28-64 at 1.3V VDD and 1.15V SOC at 2000 FCLK. Currently running Linpack on the RAM for around 4 hours. I'm happy settling with this, but if it's stable, I might try 1.25V VDD, though it probably won't work.
Last week upgraded ny 5600x/asus b450/32GB 3200 to 7700/B650M PG Riptide/KingBank 6400 CL32 (Hynix M-Die), and with tweaks I have quite happy with the final results: BIOS Settings: Memory = 6400 @CL30/38/38/80 1.4V FCLK = 2133 UCLK=MEMCLK/2 (My system fails if I run 1:1 UCLK=MEMCLK) PBO: Advanced/Motherboard, Scaller 10X, Positive 200 CO: All core, Negative, -30 iGPU = Disabled BIOS Thermal Limit = 89C Cinebench R23 Multi/Single = ~19,200/~2000 (~44-46W/~114-116W) Idle = ~49-51C (Windows 11; room temp ~23C) Games ~92C Load (Cinebench R23) All core=5.1-5.2hz @89.4C Single Core = 5.49Ghz (59-60C) Thanks for this video. I will definitely try to use some of the knowledge to see what extra I can get from my system.
Need more cheap B650 boards to fk about and find out on. 2DPC, damn Post Code, a wee Clr_Cmos on the back, a clockgen, good VRM push 1 ccd hard or pbo a 2 ccd chip with maybe no chunk of aluminum / plastic /lighting needed, maybe another pcie x8, screw the RGB and the Wifi, skimp on the rest of rear panel, skimp on sata, rear USB whatever. I don't care if the board looks brown from the wrong angle.

It's not CPU problem, I get 70 gbs read sustained in a HPC application that is 100% memory bandwidth dependant (sparse matrix CFD calculations) on 7950x3d with 64gb 6400 tuned Hynix A-die sticks, I guess it's just HCI memtest that needs updating, maybe it's balanced across read/writes but in real world apps it's like 10:1 or even more in favour of read.
@@JJFX- Of course, but it is still sad that this is bottlenecking possible performance increase. I did hear that Zen 5 is being validated to much higher memory speeds (for server, I'm not certain about Desktop, but it's probable). Which would mean that either they managed to break that barrier with fclck or that Zen 5 will have different ratio than 3:2.
Hmm the DRAM VDD setting is interesting. I've overclocked Kingston's ECC sticks to 6000 and am running VDD at 1.25V. I'm not getting any ECC errors from the DIMMs themselves, but now I'd sure like to know what the On-die ECC does.
Why is Linpack performance so low? It is lower than on my 10900k DDR4 4400 CL17 system (~640 GFlops). The Ryzen chip has more cores and higher IPC, of course, and DDR5 6000 has higher bandwidth. Is it the latency? Seems to me that top linpack performance hasn't moved in years.
Did you change your mind about what's the max reasonable VDD voltage? I'm running VDD=1.5V and VDDQ=1.4V to get CL28, 37, 37, 6200. I guess if I ever loose stability due memory degradation, I'll be sure to make a Reddit post.
@@ActuallyHardcoreOverclockingWhat does that mean exactly? Is the IMC going to degrade with higher VDD voltages? I'm currently running 1.5V VDD for 6400 CL28 and tight subtimings. The memory doesn't go over 47*C in HCI Memtest Pro at 25*C ambient temperature. I have a fan blowing directly on the memory sticks, hence the low temps at 1.5V VDD.
2033 was the sweet spot to get am5 to post with early bios's, he said pretty much all am5 are stable at 2066, but maxing a given CPU's IF only improves performance and very clearly said ymmv
on older BIOSes when using the DDR5-6000 ratio 2033 would perform best. At 6200 optimal FCLK always was 2066 or higher. AMD eventually patched the 2033@6000 thing and now at any mem ratio more FCLK = more better.
Just curious as i have this motherboard, so you did NOT choose XMP or EXPO first, you just plugged in the freqs and volts manually, correct? BTW thanks for spending a lot of time with this board, much appreciated.
If you can find out why the VDDIO + 0.1V > SOC 'rule' exists I would be very grateful. Nobody I've been able to ask who should know can give a concrete answer. The best I can come up with is it has something to do with the iGPU and VDDIO_APU voltage (which is often tied to VDDIO_MEM but can be changed on some boards). I have been suspecting a possible connection to at least some of the recent failures.
Bought one of the cheapest Kingston DDR5 expo set available, 2x8 Gb 5200MHz at 1.25V, now running stable at 1.35V 6000MHz + your recommended timings. On Asrock b650m pg. Good shit.
Is 1.5v VDD “safe” daily if your temps are good? I assumed it was as long as you weren’t running Hot..

RAM idle is ~ 30c @ 1.5v VDD Total stable for the past 5 days or so. I just don’t understand how I’m not breaking 60ns in Aida64 with my settings.. Maybe it’s because I’m running Windows 11 Pro.
Build myself a setup with 7800X3D, this board and 2x16 6000c30-38-38. I tried this guide, but latency is 63ns and read is 66k vs 6000 and slightly worse timings getting 59ns and 67k, weird.
So if I don’t follow the VDDIO VDDQ SOC rule will my system be unstable? Let’s say my SOC is at 1.15v and I want my VDDIO to be at 1.2v. Will this cause problems? Will it damage my Ram kits?
I got this board, FlareX 6000 M-die and a 7800X3D I'm building for a friend. Tried your settings and I get loads of errors in TM5. Lowering fclk to 2067 makes it work, but 6000/2167 seems to be a bit faster.
@Taraquin83 I find even relation between fclk and memclk gives me better latency. So 6200 and 2067. Despite having slightly lower throughput than higher fclk it gives me better latency than higher fclk. I mostly play cod which prefers latency over everything.

At these settings I keep getting fails in linpack at 6200 even though I'm passing tm5. Seems to be ok at 6000 with all the rest of these settings. Even if I am getting regression above 2000 IF. Can anyone tell me is anyway around this or am I stuck at 6000 and 2000 IF? If I am stuck at 6000/2000 what should I drop back a bit? Edit: Actually nevermind. Still hitting fails in linpack at 6000/2000. Need to find a ddr5 oc guide from scratch.
can someone please explain what the north bridge clock is, what setting in bios controls it, does it affect performance. also i cannot get my memory less than 66 nano seconds using builzoids own settings. btw ive seen my north bridge clock run from 900 mhz to 3450 mhz and i just dont understand whats controlling it.
I assume you're talking about AIDA and it's normal. I'm not 100% sure where it pulls that value but it changes above DDR5-6000. tPHY also often gets uncoupled between dimms during training at this point. At DDR5-6400 it stopped reporting the "NB clock" entirely. That isn't the cause of your high latency. Make sure you only run AIDA with as little as possible in the background, including Windows Defender and ensure your FCLK frequency isn't too high. Outside of that it's probably your timings.
Considering the frequency limitations on Zen 4, I haven't seen any significant difference with 2 dimm boards. They can cause dimm temps to run a bit hotter. In XOC scenarios it's possible there's an advantage.
I bought same cpu, mobo and rams. But since built, it has random rebooting issue. İt happened once during idle. No idea what to do? Is it caused by 85C limit?
not sure what im doing wrong , but i cannot get lower than 60 n/s lattency with even tighter timmings than in this video, could the fact you are using clean windows install be the reason? using x670e prime, 7950x, gskill 6400 cl32 2x16 @ 6200mhz 1-1 cl30-35-35-28-62 pyprime 9.971s
Ok this is strange, I just down clocked to 2000 fclk and 6000mhz and my Latency dropped by 2 to 58n/s the best I've ever seen on this system, pyprime 9.612s
Well it seems my 7600 has a pretty bad mc cause it cant do 6200 cl30, my ram expo is 6000 cl32 1.35v and with BZ easy timings it works perfect, i tried 6000 cl30 @1.40 v and seems to be working fine (running stress test right now) but 6200 cl30 just fails instantly, i havent tried 6200 cl32 but that will be better than 6000 cl30?
IME Asrock has been very good about setting what it's supposed to and at least my Taichi has been a surprisingly reliable board. I wouldn't be surprised if some versions had a voltage bug but I haven't been able to trigger one (except the DDR5 PMIC high voltage bugs that affect everyone).

I'm noob to OC, but i set the BIOS at my Asrock B650 PG lightning to 'PBO with tjMax 75, curve optimizer -20mV'. I'm not sure if it was a good or bad thing, and i hope somebody could tell. So what i can observe, My CPU temp never exceeded 80 degree. Reaching 90 before with auto setting. When playing Ultimate Admiral Dreadnought with max setting. TLDR 10-15 degrees celcius lower than before. But i have no idea if it would affect system stability or performance. I gained a few fps actually but that game has quite erratic reading. So I'm not quite sure. My processor is Ryzen 7600, the one with the free fan. Using 2x12cm Noctua redux case fan. Now, i also question if the cooling system is adequate.
It would basically limit the max cpu temp to 75 and reduce performance to stay below that temparture, and also does undervolt of -20mv which helps getting more performance with less power but potentially can lead to instability If you are using stock cooler you should try the -40mv setting and see if it is stable, that way you would achieve higher sustained clocks without throttling = better fps I tried manually setting on my 7600 -50mv and it helped it clock higher and still be stable, tho I didn't test it enough

You need to downgrade your bios, and up your SoC, it definitely scales with FCLK. From my X670e Steel Legend/7900x; 6000 (xmp) 2133Mhz stable at 1.275set (1.295vrm) holds true to 6200Mts; at 6400Mts I had to up it to 1.325set(1.360vrm). Also you should probably review the mega-thread, "AMD DDR5 OC And 24/7 stability" on overclock net
Tried it, didn't work. CPU: 7900X3D, Mobo: Asus Strix X670E-A, RAM: 2x16GB Corsair Dominator Platinum 6200MHz 36-39-39-76. Not sure if it's because of X3D, but I tried several different timings and the major determining factor seems to be that my chip just doesn't want to run at 6200.
AFIK, the 7900 has the worst binned dies (except for the 7600) and since the 7900X3D is the only X3D SKU with completely non-functional cores, its average silicon quality seems to be significantly worse than even the 7800X3D.
I got mine at 5.25 GHz with PBO +200 and Curve Optimizer -25mv. With fix OC you will probably get 5.350-5.4GHz, but needed voltage may vary depending on concrete CPU example
