Hey everyone,

About a year ago, I was experimenting with undervolting my MSI RTX 5070 Ti Gaming Trio OC Plus.

My main goal wasn't just to reduce voltage or get higher clocks. I was trying to answer one question:

Is there a way to undervolt the GPU while keeping the lower part of the V/F curve close to stock, so the card can still drop to its normal idle clocks (~180 MHz)?

Some of my earlier UV curves resulted in much higher minimum clocks at idle.

I found a curve editing technique online and started experimenting with it in MSI Afterburner. It uses Ctrl + left-click to tilt the V/F curve, Alt + left-click to move it down, and then flattens the curve above the target voltage.

I didn't invent this method, just adapted it for my own testing.

Here's my short demonstration: https://youtu.be/09i5ctr1EDI

Back then, I was aiming for around 3100 MHz @ 935 mV.

After almost a year away from gaming, Call of Duty got me back into GPU tuning. This time I went for a slightly more conservative profile: ~3000 MHz @ 935 mV, which has been stable for me so far (COD MV4)

Some results from 20 loops of 3DMark Speed Way, logged with HWiNFO64

- Target GPU clock: ~3000 MHz @ 935 m

- Average effective clock: 2968 MH

- Reported core voltage under load: 930 mV\

- Average GPU power: 275 W

- Average core temperature: 63.6°C

- Average hotspot temperature: 73.3°C

- Average fan speed: 1426 RPM

- Memory offset: +1000 MHz

- Idle GPU clock: ~180 MHz

While trying to understand how and why this method works, I used ChatGPT Deep Research and Gemini Deep Research to explore the technical side of it. I then combined the results into a single PDF using Google's NotebookLM.

So the document is basically a mix of AI-generated research and explanations, together with my own test data. I'm not really sure how accurate all the technical conclusions are, or whether they fully explain what I'm seeing.

What do you guys think? Does the explanation make sense, or am I missing something?

The interesting part for me is not the 3000 MHz target itself, but getting this behavior under load without losing the low idle clocks.

I'm also curious if anyone else has tried this approach or found a simpler way to achieve similar results.

I wanna/need to undervolt my RTX3060 and i have absolutely no idea what i am doing, or what i should be doing to begin with
and everything i saw online has an older UI which i cannot translate to this one

so help would be much appreciated

Do you think i would get a higher sustained load if i were to cap the voltage but increase the offset or i get a higher max performance by having higher voltage?

The problem is, if +320 is already at the edge of stability, where it crashes usually once every 24 hours of pure gaming or a little more than that, if i decrease the max voltage but increase the offset, why would i assume that it could be stable? Like let's say that at 1.04 volts it can go up to 3150 mhz, if i increase the offset to 450 but cap at like 1.01 volts, 1.01 volts might reach 3200 mhz.

However how can a higher frequency even be more stable at a lower voltage?

What do you think?

Took me so long as a beginner to finally get a really fast stable profile, how do these timings look? Anything to improve on or shoot for? I dont have enough space in my pc to put in a ram fan, I might install one later on but I’d have to do it DIY so not rn.

im also on +200MHz and -25 undervolt on all cores except logical core 1 on -10 which seems to be the weakest link.

Thanks to some of you on here recommending some of these tests to me, my input latency has never felt better.

I’m not really into overclocking and don’t plan to push my CPU much. I’m just curious about my SP score. I have an ASUS ProArt Z890 motherboard running the latest BIOS. If there are any other Core Ultra 9 285K owners here, what SP scores are you getting?

hi im quite rookie i already undervolted my card switched few options in bios and now i don't know what to do next to get that few extra %

I’m looking for the best stable high performance settings and tight timings for long gaming sessions.

I have a 9950X3D cpu that’s overclocked and stable.

I don’t want the timings where I’m just near pushing instabilities

Any recommendations for this ram?

Hi guys

I'd like to know which method is better suited for AAA gaming: using the latest mVOLT+ to override voltage limits in the BIOS, or adjusting the V/F curve?

Sorry for making another post, following the advice of others, I decided to run my config at 8000MT but I'm at a loss as to what I should change (other than TREFI)

**EDIT** Here are the new timings provided by SL1M_GG. I used TRFC provided by Obvious_drive

Any advice as to what I should do?

Hello i recently tried my hand at tuning my r7 5700x and wondered if i could improve my settings more or if i should lower them.

Tested with corecycler and cinebench 23 and looks to be stable, got 13989 on cinebench.

4070 ti super user here. I set 2730Mhz @975mv + 1000Mhz on mem.
Via afterburner, speedway benchmark score was 64xx. Clock speed dropped under 2700 sometimes. Unstable clock speed.
Via Mvolt, score was around 6700. Stable 2730Mhz. Really good!

Added xbar + 200Mhz, the score became around 6840.

Changed mem to +1500Mhz, the score became 7000.

It feels like overclocking xbar can improve the boost from mem overclock!

Summary: I got around 11-12% performance boost from stock via uv and oc!

Can someone give me the proper overclock settings for the 9950X3D

Everything you’re running for high performance for gaming.

Also,

DF C states enabled or disable, SMT enabled or disabled or anything else that will make a difference?

It’s a brand new chip on the ASUS ROG x870E mobo

All help is appreciated

This is the farthest I can push this card on stock air cooling (I think?). This is my first time owning and testing an astral model. I have 2 other 5080 models that just fall short of 10k. I’m just wondering if this would be considered a good bin and if it’s worth pursuing a water block.

+415 Core
+3000 mem
Xbar +450
Sys +300
Voltage cap at 995mV
Power limit maxed

Could you please advise on what settings to use to achieve the maximum frequency for my RAM?

I have had a 13700K now for the past few years. Right when it came out, I got it. Fast forward a few years, cpu goes bad, i get the microcode update, get a new CPU and here we are. I built this system originally with an RTX 3080. For ram, I was thinking, why should I buy some more when I have a good kit from my 6700K. So I farmed that 4x8GB part to this new build (bad idea). Honestly gaming was good, but never great. I always had these stutters. No matter the game I played, the stutters were always there. Kind of got used to it, thinking it is what it is.

Fast forward I got a 5080. Bagged one for $1100, thinking this will resolve my issue for sure. FPS went up nicely, but guess what, stutters still fucking present. in-fact, now they are just MORE OBVIOUS.

I know the ram is the flipping culprit. Questioning if it is basically really worth considering upgrading the ram, or just say fuck this platform and move on when Ryzen 10 drops.

Did some research and with some guidance, I found a 2X 16GB DDR4 4000 (16-16-16-36) 1.4v on ebay for $250 shipped.

During this time of waiting, I start reading, watching videos, looking at the cheat sheet, just to have some understanding of what I am going to need to do.

Installed the ram, spent about 8-9 days of testing and tuning. This is what I ended up with. Ram Timings are in the Picture.

Ran Prime for 4 hours and no problems. Ran Anta777 Extreme for 7 Cycles and passed.
Max temp on the ram is a bit high, 46.2C for DIMM1 and 44.2 for DIMM3. I am getting the heat spreaders from AlphaCool and the gelid ultimate pads tomorrow to drop temps another 4-7C. If temps drop to 40C, I will max tREFI, is what I am thinking. Dropping system latency to about 43nS.

Overall Performance improvements

I didn't have much of a test bench. I only tested 2 titles and Cinebench R26. Plus my testing method was probably shit 😂.

I kept my same mVolt+ profile to try and make this as fair as possible. GPU is an RTX5080, which is scoring about 9850 on Steel Nomad for daily driver profile.

These test were performed on my system and these are the performance gains I have seen in games and in synthetic testing. I would say In the end, this was the most impactful upgrade of this build. There are no stutters. No matter the game I am playing now, they have completely disappeared. Frames are much more consistent, while max FPS did increase about 5%, My 1% lows shot through the roof. System responsiveness is on another level as well. This should definitely last me a couple more years. This just proves that memory sub-timing optimization is often more impactful than a raw CPU generational upgrade. Very happy with the improvements. It genuinely feels like I got a whole new Platform.

I have a 9950X3D, and I managed to achieve a stable -30 curve optimizer with curve shaper. But I'm noticing that when I have an intense workload, the computer really becomes unusable: mouse movement goes out the window, things take a long time to activate, Alt+Tab takes forever, etc. So this is not even about gaming.

I'm aware of what a full system load feels like, so this is beyond the normal lag on full system load.

My temperatures are great during said problems, 75-80 C. I can get it to 95C under stress testing, but when the problems happen, it's only around 80C.

I've seen plenty of overclocking results where a system looks stable because it can finish a benchmark or run a game without crashing, but I'm curious how people here decide when an overclock is actually reliable enough for everyday use.

A setup might pass a quick stress test and still develop errors during longer sessions, different workloads, or temperature changes. Memory tuning seems especially tricky because an unstable configuration can cause problems that don't immediately look like RAM instability.

I'm interested in the testing routines experienced overclockers actually trust, whether that's extended memory testing, repeated benchmark runs, checking error logs, or simply using the system normally for a while.

How do you personally decide that an overclock is stable? Have you ever had a configuration pass your usual tests and then fail in a completely unexpected way?

Is this 5070 ti overclock good? Steel Nomad Score: 7 529

MB: Asrock b550 pro4
cpu: ryzen 5700X3D CO -20 its was stable for 2 year of use
ram: G.skill trident neo 3600mhz cl16 Dual Rank Hynix CJR Voltage 1.38
The memtest5 throw error randomly sometime first 10 sec , sometime around 10min, sometime complete 4 hours but last 5 test i done throw error at 10 sec , this is a new ram kit i bought but i was playing like this for week with no game crashes no BSoD .
Default XMP no overclock and no change on Timing

is there anything i can do to make it stable in memtest5 ?

I am getting frequent micro-freezes in games and occasional system stutters.

The pattern is always similar:

• GPU usage is stable, for example around 50–70%
• then a micro-freeze happens
• GPU usage suddenly drops to 20% or even 0%
• at the same time, Disk Active Time jumps very high, sometimes to 100%
• Average Response Time jumps from normal values to 3,000–9,000 ms
• disk throughput during these spikes can still be extremely low, sometimes only a few KB/s or a few hundred KB/s

System drive:
PCSPECIALIST PCS3480 2TB NVMe SSD
Firmware: SN11665
Interface: PCIe 3.0 x4
Driver: Microsoft Standard NVM Express Controller

Tests already done:

• CrystalDiskInfo: Good, 91% health
• Critical Warning: 0
• Media and Data Integrity Errors: 0
• Error Information Log Entries: 0
• Temperature around 41–42°C
• CHKDSK /f /r: no file system errors, 0 KB in bad sectors
• WinSAT: around 1993 MB/s sequential read and 2639 MB/s sequential write
• Clean Boot: no change
• Microsoft Defender disabled for testing: no change
• PCIe Link State Power Management disabled: no significant change
• NVIDIA Overlay disabled: reduced micro-freezes, but disk latency spikes still remain
• Realtek 2.5GbE controller disabled: slightly fewer freezes, but problem remains
• Event Viewer does not show obvious stornvme / disk timeout errors
• Storage Reliability Counter has shown ReadLatencyMax / WriteLatencyMax / FlushLatencyMax around 4,000–5,000 ms

The strange part is that the SSD benchmarks normally and SMART reports no problems, but during normal use or gaming it occasionally stalls for several seconds.

Could this be caused by:

• NVMe controller/firmware instability
• StorNVMe driver
• PCIe link/controller issue
• motherboard/chipset issue
• or a failing SSD that still reports healthy SMART?

Any ideas on how to properly diagnose these intermittent NVMe latency spikes?

Problem
I’m trying to get DDR5-6000 EXPO stable. I’ve been running OCCT CPU + RAM tests and experimenting with CPU VDDCR_SOC voltage. EXPO is enabled and UCLK is set to MEMCLK (1:1) for the 6000 MT/s tests.
OCCT test history
DDR5-6000 EXPO, UCLK 1:1
VDDCR_SOC 1.265 V: First run completed 1 hour with zero errors.
VDDCR_SOC 1.265 V: Second run — OCCT GUI crashed after approximately 20 minutes. Windows remained running. Reliability Monitor showed BEX64, exception c0000005, faulting application OCCTGUI.exe version 17.1.10.99. No OCCT test errors were reported before it closed.
VDDCR_SOC 1.265 V: Third run — one OCCT error at approximately 43 minutes. Exact error details not yet recorded.
VDDCR_SOC 1.270 V: Errors started appearing repeatedly after approximately 12 minutes.
VDDCR_SOC 1.255 V: OCCT errored also around 12 minutes.
Other testing
DDR5-5600 with EXPO enabled: Passed at least 21 minutes, and a later run reached 40 minutes with zero errors.
DDR5-4800 with EXPO disabled: An earlier run showed zero errors for approximately 14 minutes; this was not a full stability test.
DDR5-6000 with UCLK = MEMCLK/2 (1:2): Previously ran for at least 20 minutes without errors; full test result uncertain.
What I’ve tried / questions
BIOS is updated.
I’ve tried different VDDCR_SOC values, but higher voltage hasn’t consistently improved stability.
I’m not sure whether this is a RAM kit issue, the CPU’s integrated memory controller, motherboard/BIOS settings, or something else.
What would you do to get it running fully stable or is 1.265 stable enough i wont get issues? ( doubt) attached is zentimings from when i tested 1.28 (gave errors)

Been tuning my T-Create Expert 6000C30 2x16GB A-die kit paired with a 9700X + ASUS B850-I. Cooling is a bit limited since I’m in a Midori 5L with an L9a. I replaced the RAM heatsinks with ZCOOI full-aluminum ones, and adding dedicated RAM fans may be possible.

Current setup is 6000 28-36-36-36 with tightened secondaries, UCLK=MCLK, 1.36V VDD, 1.35V VDDQ and ~1.25V SOC.

At 1.35V VDD, TM5 Absolut gave 1 error after ~29 minutes. I bumped only VDD to 1.36V and it passed 6h27m / 14 cycles with 0 errors.

I also tried 6200 1:1 with FCLK 2067, but it became unstable during boot and threw a few winload.efi recovery errors. After resetting everything, Windows was fine and both SFC and DISM came back clean, so I’m assuming the 6200 setup was just unstable.

CPU is currently PBO limits Auto, scalar Auto, +200MHz boost override and -25 all-core CO. Switching from motherboard limits to Auto dropped R23 multicore from ~21,500 to 20,233, but temps dropped from ~95C to ~80C and power to ~88W, which seems like a much better tradeoff for an L9a in a 5L case.

I’m mainly tuning for high-FPS CS2 rather than benchmark scores. What would you guys improve next? I’ve seen mixed opinions on pushing 6000 tighter, going for 6200/6400 1:1, or even 8000+ MT/s. I’m still pretty new to the tradeoffs between frequency and timings, so any insight would be appreciated.

Ive tested every setting available with full voltage sweeps between them and nothing has given me stability. previously I hid some resistances on a post so here they are, if your chip needs more vddp but the sweetspot vddio is below the minimum for vddp these resistance changes to rtt's and procodt have been found to push the vddio sweet spot up a bit atleast on my system its not much but it let me get from passing 10 minutes to an hour 40. Because im a stubborn idiot I will keep messing with my resistances and cad bus and hopefully something I overlooked was the issue but this chip has issues with gdm off, even 8600 gdm on works so in theory 8500 gdm off should also work.

Hello! I’m running a Ryzen 7 9800X3D. My motherboard is an ASUS TUF B650 PLUS. I have a Hynix A-die 6000MHz CL36 2x16 single rank, dual channel kit from Corsair (Corsair Vengeance). My cpu is watercooled, I have an MSI Ventus 3x OC 4070 Super, but I do not have a dedicated RAM fan.

For the longest time, I’ve had “EXPO I” selected in the Ai Tweaker section of the BIOS and forgot about it. I have not encountered any issues in games whatsoever, nor in Windows. I had the voltages and whatnot set to Auto.

A few days ago, I stumbled across Buildzoid’s video from early 2023 and mindlessly copied his Hynix A-die settings. Of course, they aren’t tuned for my kit in particular. Is there anything better I can use currently? Obviously ideally I go through the entire process myself but I haven’t had a lot of free time lately due to university so if someone kind could help me out, regardless if feeding me straight timings or a cheatsheet or their own two cents, I would be very grateful :) Best I can do atm is leave AIDA/Karhu running while I go to uni to test stability which I haven’t done previously on EXPO I since it always worked fine. A little scared to mess something up so I’d appreciate some general advice
