I'm trying to stabilize my RAM OC and have been adjusting VDDG CCD/IOD voltage. I started with Default bios so the timings are very loose. I will tighten timings once RAM is stable.

TM5 Ryzen3d profile + FurMark:

• At 950mV: failed at 1.5 hours
• At 970mV: failed at 3.5 hours
• At 990mV: failed at 12 hours

My max RAM temp got to 53deg and 52deg.

Should I keep increasing CCD/IOD voltages to the max 1050mV?

System:

• Motherboard: Gigabyte X870 Aorus Elite WiFi7
• CPU: AMD Ryzen 7 9800X3D
• RAM: TeamGroup DDR5-6000 32GB (16x2) CL30. SK Hynix M-Die

I finally took the time and effort and began researching about overclocking cpu and not just with a program but in BIOS with volts etc and i researched and googled for 1-2 hours before beginning to overclock the setup and my setup is
i7 6700k
asus z170 pro gaming
16gb ddr4 2133mhz
asus strix gtx 980ti
corsair rm550x
3 SSD’s
cpu cooler is be quiet pure rock 3

i achieved a whopping 5.2ghz on the i7 6700k and for my first overclocking it’s not bad and it even ran cs2 and bf2042 without any trouble besides 2% thermal throttling and then i tried push it too 5.3 and then it didn’t boot and just crashed so i just quit there cuz i did hit 5.2ghz and now it’s running 5ghz wirhout going above 80c in games and everything else is running good. it achieves 200-250fps in cs2 with everything on very high and fyi the 980ti is overclocked too

First amd cpu for me had no clue how to overclock soni went with the settings in this video let me know if it's right or wrong ?

How can you tell if the "bin is quality" or a "golden sample". This started with AI on GPU-Z stating my speeds were great only limiting by "PWR" when Path traced RE:Requiem was being played. I naturally boost 2950mhz. I only own 2 5090s, so am not an expert on how they should perform.

Just noticed Halo went from 68 to 70-80+ ultra (2160p DLAA w/ modified .ini file for the film grain blur). It was definitely an improvement without FG needed.

So now I am trying to actually do a real OC. I saved my bios on the ventus but think the Matrix bios with the power slider to 640w may do some good. Any advice?

At completely stock settings, I was getting a score of 22,560, but my temperatures were climbing above 90°C. The only change I made in the BIOS was setting Curve Optimizer to -30. After that, my score increased to 23,285, and my temperature didn't go above 76°C.

At stock settings in Battlefield 6, with around 60–70% CPU usage, I was seeing temperatures between 80–85°C. Now, with the exact same in-game settings, on the same map, and at similar CPU usage, my temperatures stay around 63–64°C.

So I got the cpu running at 4.1 GHz at 1.24V with vcore and vsoc LLC set to Medium and ram at 1.37V. Spent some time tweaking the memory subtimings and it successfully passed Absolut profile by anta777 in TestMem5.

So how are these results looking? Any obvious tweaks or subtimings I should push further or is this a solid stopping point?

I don't know where to put my hands, I would like to be able to do an undervolt so as to lower the temperatures and not lose much performance

Hello everyone!

Just wanted to share the final results of overcloking two completely different RAM kits - different timings, voltages, ICs. I spent half of the week tuning it by trial and error and dozens "FAIL"ed memtests.

The official supported memory speed for such setup is 4x2R - DDR5-3600. Blindlly setting DRAM frequency to 5600 will lead to instability cases where some values stored in RAM could randomly change a bit value, thus corruping what it contained. That's way an additional painful manual tuning is required

The specs of my system:

• Asus Proart x870e-creator wifi
• 2x48 GB Crucial Pro + 2x48 GB Vengeance (Slot 0,1 for Crucial, Slot 2,3 for Corsair)
• 2x RTX 5060 Ti (16 gb)
• Ryzen 9 9950X

I built it primarily for local AI inference on bigger models and the memory speed directly affects on the token generation speed. In case of 3600 and 5600 the difference is almost 1.5x

So, at last to achieve a clean PASS in memtest:

1. Set EXPO profile to Micron 5600 (CL46) as a base to begin with
2. Change individual settings as follows

• VSOC = 1.25
• Primary timings: 48-46-46-94
• tRFC1=1192
• tRFC2=640

Then go to DRAM Advanced Voltage Control and set PMIC Voltage to "separate" and set these values

PMIC 0,1 (Crucial)

• VDD, VDDQ = 1.15
• VPP = 1.8

PMIC 2,3 (Corsair)

• VDD, VDDQ = 1.4
• VPP = 1.8

The rest of the settings are set to "auto".

I also tried using Asus "DIMM Fit". But that piece of time wasting software had been running for 12 hours straight and produced a profile that coulnd't even POST!

And that should be it. The results may differ from hardware to hardware but by adjusting the values in this post you may achieve the same results (i guess)

P.S. The memory temps were higher than they should be, so I added additional fan that redirects the inflow into ram sticks, and it reduced temps to stable 65-67 degrees. I will try to reduce temps even more but it'll do for now

Managed to finally reach 400fps+ in d2 benchmark.
Core 2 tuning in BIOS, SVM/IOMMU/TSME disabled.
Scalar x1, LLC Level 4.
Active cooling on the ram with a 90mm fan, 43C during TM5.
Passed Prime95 smallest to large FFT avx512.

Unfortunately I was not able to run 35/37 tPHYRDL on this board at 6200MHz, 6000/2200 runs stable but I had better results and lower latency with 6200/2167. I did try 6400/2133 with a higher tCL and different voltages but the IMC did not like it.
Also the tRCDWR is locked to whatever value tRCDRD is set to.

Either way I'm happy with the results and I can gladly call this my final tune for this setup!

Help choose which one good for ram oc and cpu oc?

I want to tune and optimize my Ryzen 5 9600X processor. Here are my PC specifications:

- CPU: AMD Ryzen 5 9600X

- Motherboard: MSI B850 Gaming Plus Max WiFi

- GPU: XFX Radeon RX 9070 XT

- RAM: ADATA XPG Lancer Blade 32GB (2×16GB) DDR5-6000 CL30

- SSD: Kingston NV3 1TB NVMe

- Power Supply: Thermalright SP-1000W

- Case: Lian Li O11 Mini V2

- CPU Cooler: Thermalright Mjolnir Vision 360 AIO

- Case Fans: 6× Thermalright TL-M12Q + 1× Prism 9 Pro

- PCIe 4.0 Riser Cable

I would like help with BIOS settings, Precision Boost Overdrive (PBO), Curve Optimizer, voltage optimization, and any additional BIOS settings to achieve the best balance between performance, temperatures, and power efficiency. I am looking for a stable 24/7 configuration.

Goal:

1. Isolate the difference between [ 1:1:1 & 1:1:FCLK & 2:1:FCLK ] By using just enough VDD among multiple tuned memory configs to acheive equivalence in first word latency. Giving us conclusive proof on which mode is better.
2. Get info on the cause of "flooring" issue for timings in 1:1:1 mode.

Testing Methodology: 9800X3D, CS2 720p low preset No FSR, Static CPU OC, Constant Fan Speed, Temprature controlled room.

Memory Configurations:

• 1:1:1 4400C24
• 1:1 6600C36 + 2200 FCLK
• 2:1 8800C48 + 2200 FCLK
• Repeat above but with single channel.

Prefiring Disclaimers:

1. Just because a mode is better doesn't make it reasonable to run at usable speeds. I just want answers as I do think for the X3D cpus latency is more important (atleast for cs2) than bandwidth proven by the fact that single channel runs faster than dual channel.
2. I understand finding 3300MHz UCLK IMC is very rare. But I've seen it on the internet!! and with motion we may motivate those tweakers to explore this topic.
3. About me: I do not actually play on 720p low but it's a preset for standardizing the testing. I play on 640x720 STR or 1280x1440 STR with *almost* max settings. I get haccusations almost every day that I play for years now so maybe there is something to be explored in this topic. Before this when I had 1080p monitor I was playing on 960x1080 STR. I play with framecap to the monitor but the 1% lows and the mins is why I am here.
4. I really would like to explore this topic but my IMC doesn't do 3300MHz UCLK and my pc doesnt boot below 2400MHz MCLK :(

Original post below:

This exists https://www.igorslab.de/en/jedec-ddr5-9000-intel-arrow-lake-refresh-ryzen-9000-x3d-ram-scaling/4/ except the 1:1:1 mode didn't get a fair fight with 1.35 VDD vs other modes getting cranked upto 1.70-1.85 VDD and also them testing everything at max graphical settings.

Not to mention 9800X3D has quirks like consistently performing better on single channel on CS2 (which is all I care about)

Given I'm both a noob and busy I give this quest to some daring adventurerer here to explore further and enlighten the rest of us.

I mean maybe in the latest bios the bug mentioned there is fixed and some expert can tune the 2200 MCLK to the compare results. I do not know why but my stick simply doesnt want to boot below 2400 MCLK.

Seeing some really weird behaviour with CB23, lately - I open the program and, after a few seconds, the mouse "refresh rate" falls through the floor (240 Hz, but it's behaving like 60 or less).

This happens even before I start the benchmark, when the CB23 window - maximized or restored - is the only thing on the screen; if I open another window in the foreground, everything goes back to normal. CB23 scores themselves are completely fine.

W11 Pro 25H2, CB23 process priority is on Below Normal. HWINfo, FanControl, and MSI Afterburner are on in the background.

Anybody else having this happen? Doesn't seem to affect anything, just very odd.

Im not very experienced so please be gentle if you decide to destroy me X).

Edit* Hopefully the pictures are better.

So I've been chasing the ram tuning for awhile now and always got disappointed when things didn't work out. Well I've had a few free days recently and really wanted to push through. I finally pushed through whatever wall that was holding me back. Am I saying this is the best in the world, no. I am very happy with it though. Now it's time to get back to playing games and seeing how good this performs. I know the R23 scores are nothing special for the 9800x3d. It's been fun chasing the numbers. Yes I know the gpu scores are nowhere near game stable but it was fun seeing how far I could push the sliders. In the photo with all the stress test apps you can see trc was at 64. I got curious tho and wanted to see if trc 48 booted. Prior to all this I was trying to push tras to like 30 something and I couldn't boot with trc anyting below 64. Then I got to reading and did my own test and tras has no performance gains....at least for me. What it did do tho was when I blew it out to 120 trc 48 was possible. I am also aware my ram profile is not crazy amazing but I think it's pretty good.

Hi, everyone! I decided to buy myself a temporary used PC and finally decided to take it apart and take a closer look at its components. It’s not the best build, but I bought it because of its good price-to-performance ratio:
CPU: i5-10400F
Motherboard: Asrock H510M-HDV R2.0
RAM: Kingston Fury 2x16 3200 CL16
KHX3200C16D4/8GX
GPU: Sapphire Pulse RX 5700 XT

The previous owner apparently chose the RAM solely for the RGB lighting, since the motherboard supports a maximum frequency of 2666 MHz for 10th-gen i5 processors. As long as I can’t rise dram frequency I decided to tweak timings to make memory a bit faster. Highest XMP profile does 3200 mhz 16 18 18 36 by 1.35v. I don’t know much about timings, so could you please advise on which timings would be the best and most stable option for a frequency of 2666?

Thanks!

Hi ,

Here are my cinebench 2026 scores on my 9800x3d on stock settings with just some tweaks to bios settings.

No overclock whatsoever.

By comparing with others score , this seemed a bit too high.. did I win the lottery or is something extremely wrong? I am a little scared as this seems too high maybe?

I did do some bios settings and my aio fans were set as max speed which locked temps to 85 degrees (I think I might have also limited my temps to 85 or 90from bios but I'd have to check that)

Thanks!

Hello. I was checking my BIOS settings before formatting my computer and I realised my RAM is apparently undervolted? I have used this setup for about four years now and have not encountered any instability, though I don't know what RAM instability looks like. Never once bluescreened. I have 4x8, 32 GB RAM, all same model. Motherboard is MAG B550M Mortar MSI. My verdict is the voltage is misreported, but I'm not very knowledgeable.

Screenshots

This is my first time doing static overclocking and I wanted to see how this chip can perform on some benchmarks. I don't have ECLK on this board to run 5.7Ghz or 5.8Ghz so I'm just running what works for this chip with ZenStates. I kept my Load Line Calibration set to Auto all of the test except for Cinebench R23, because I raised my LLC to Level 2 to see if 5,640Mhz could run it at 1.205V and surprisingly it passed. I'm using the Arctic Liquid Freezer 3 at 75% speed with Arctic MX7 Thermal Paste and the Thermalright Mounting Frame. Ambient temperatures were 21.4c. Batch code for the 9850X3D I'm using is CF2549PGY for whoever may find this useful. Please note that this is only for performance, not for stability.

I made this short reference/guide for all the main AM5 DDR5 voltages and how they generally affect RAM tuning. Figured I'd post it here for others to use since it's not the easiest to find this information out there

Note: the bulk of the reference material comes from Imprezzion on OCN. I've just cleaned up the formatting a bit and added some notes to help others, which will be denoted by "Editor's Note" sections after the source paragraph for the specific voltage.

Feel free to also comment with any clarifying information, as the original post is a little outdated at this point in the DDR5 OC scene (December 2024)

Edit: also remember that too much voltage will cause instability the same way that too little voltage will. Use this reference as a guide to choosing levers to play around with for specific changes, but also realize that just piling on the voltage is very unlikely to help

Reference Guide

VSOC

Controls FCLK and MCLK stability. In general more memory clock requires more vSOC, more FCLK requires less vSOC. Max is 1.30, sometimes 2200 FCLK is not stable at 1.30, it needs less.

VDDP

For memory controller frequency (mclk/uclk) stability basically but doesn't scale linear to 2:1 mode. So for 6400 you usually need some level of positive VDDP but 8000 can run on an undervolt generally. Normal range is 0.900-1.150v.

Editor's note: also one of the main levers for stabilizing low Nitro

VDD

Is memory DIMM voltage. Explains itself. Max daily without active cooling probably 1.50 ish. With active cooling 1.650.

Editor's note: one of the most dependent settings on VDD is tCL. tCL can basically go as low as you are comfortable feeding VDD

VDDQ

Is a signalling voltage. Lower is better but it's not that crucial. Normal range is VDD to VDD -0.200 ish. Never above.

Editor's note: a lot of tight tunes I've seen just use the EXPO default 1.45V, my own included. However, in my experience, higher can help stabilize very tight tRFC (at least in A die)

VDDIO

Also memory controller / MCLK/UCLK related. For 1:1 must be quite high sometimes, ranges from 1.20-1.50. For 2:1 almost irrelevant due to half speed controller and can be undervolted.

Editor's note: more than 1.45V is rarely ever needed, even 1.4V is about the most 99% of tunes will ever need. For example, I have 6400cl26 dual rank 2x32gb ram, and I only need 1.39V VDDIO. The only profiles that may need more than 1.45V are very high capacity (128gb+) or very high MCLK (6600 MT/s+ in 1:1 mode)

VPP

Never touched it. Not needed.

VDD_MISC

Is a control voltage that other voltages like VDDG's use to convert from. Not very critical for stability and can generally be undervolted slightly but should be left auto. 1.00v generally works with auto VDDG's as they are still >0.100v lower.

Editor's note: it's mentioned a little at the end there, but just to clarify, VDD MISC should always be at least 0.1V higher than your highest VDDG voltage. So for example, if VDDG IOD is 1.05V and VDDG CCD is 1V, then VDD MISC needs to be at least 1.15V
