First and foremost, understand that anytime you overclock hardware it comes with risks. I made this guide in hopes to answer some questions people have been asking about the software, and as a starting point for anyone else. All of this information has come from my personal testing, or information from the overclocking forums.

All information should be in the pictures, but feel free to leave questions or comments for others.

From my understanding, some of the lower class cards do not have access to msvdd so the tuning may be different. I know this works with 5070ti - 5090.

Did some messing around today, and got the #1 highest score for my hardware combo (AMD Phenom II X6 1035T + ATI Radeon HD 5770) on 3DMark Fire Strike today. Interestingly this also makes me the highest scorer for this GPU in my country (Jamaica). Just thought I'd share with you all, cool accomplishment.

I was able to do it by overclocking my GPU to 945Mhz core and 1301Mhz memory using MSI Afterburner. What's funny though is that 2nd place (previously 1st place) had their card on stock clocks.

Hi, I'm currently tuning my RAM Timings (Hynix A-Die) on 6000MHz DR and every possible setting for those timings seems logical besides tRCDWR.

I tested three full cycles with TM5 Absolut without any errors, and also a long time with OCCT. Somehow this timing does not matter for that as I tune it down.
I had in some stability tests tRP one number too high, at that time I could lower tRCDWR only to 5, but this was because of lower stability reserves I assume.

The BIOS shows that this value is actually applied, so it is not a incorrect reading of ZenTimings.

Is it maybe because of GDM? I also haven't completed my tuning yet, I still have to optimize tRFC and some other values...

Can anyone please explain if I'm just being stupid or hel me understand it?

I found another kit of Aegis G Skill 2x8 GB kit (using the same Samsung C-Die I have) for 70 euros (used).

Is it a good deal as an upgrade (4x8GB total)?

I have a Ryzen 7 5700x and I am a bit afraid about the memory controller. The memory runs fine at 3200 MHz (2x8 GB) now with some tweaked subtimings.

Sharing since I have not seen people discussing this in English so far. It came out in china about three weeks ago and I just got it in taiwan.

Im sure youre all familiar with what it does if youve watched any computex 2026 cooler master sponsored youtubers but basically it flashes red and then buzz and then cuts the power if the amp gets too high. The specific numbers are on the manual.

I can’t test it right now because my pny screeching gpu is in the warranty and only have a 5080 so I probably can’t test it properly either.

If you read the manual it says 1 year warranty but that’s just for this adapter itself. What we all care about is the warranty for the gpu it’s protecting. This is where this thing diverges from thermal grizzly’s solution vastly: it covers 3 years of full compensation of the damaged gpu if the gpu connector melts but this chinese release only covers gpus bought in MAINLAND china AND you must provide a legal invoice and they will compensate based on the price listed on your provided invoice.

I live in taiwan and I bought my gpu in taiwan too so I won’t have any of that coverage but mainly I guess I bought this purely for the peace of mind. What’s interesting is this regional insurance policy.

Thermal grizzly’s insurance is global afaik. I wonder if this is just for the Chinese release or what I more likely to believe is that this thing straight up is never releasing globally.

Also one more thing that makes me almost facepalm irl is that they put these velcro pads in the packaging which I guess means they suggest us mounting it with them? Is drilling a couple more screw holes that hard for them???

Artic MX-4 performance after a year or more on CPU? What are your long-term experiences with mx4 (but also mx6) thermal paste? Have your temperatures worsened after 1/2 or 3 years on your 7800x3x/9800x3d or Intel? On my 9800x3d with mx-4 and Thermalright Phantom Spirit 120SE after 1 year I had an increase of 6 degrees in cinebench 23, obviously at the same ambient temperature. So I deduce that the pompout also exists on the HIS! It's not just a problem with direct die GPUs! Is mine an isolated case or is it normal? Thanks everyone for any information you may have.

Hi guys. I’m looking for some advice on stabilizing 2133 FCLK on my Ryzen 7 9850X3D while keeping DDR5-6400 1:1.

Setup:

• Ryzen 7 9850X3D
• MSI MAG B850 Tomahawk WiFi
• BIOS 1.A42 / AGESA ComboAM5PI 1.3.0.1b PatchA
• G.Skill F5-6400J3239G16GX2-TZ5RK, 2x16 GB
• DDR5-6400
• MCLK 3200
• UCLK 3200, 1:1
• DRAM VDD/VDDQ ~1.41 V
• CO -25 all-core
• +200 MHz Boost Override
• PBO Scalar Auto

I’ll attach a ZenTimings screenshot with all primary/secondary timings and current voltages.

The RAM itself is stable at 6400 1:1.

FCLK / SoC testing so far:

2067 FCLK / 1.27 V SoC

• Originally passed ~2h TM5 Extreme @ anta777
• WHEA clean
• Later, with the same settings, TM5 produced one error at around 19 minutes
• I immediately repeated the test without changing anything and it passed 30 minutes

So 1.27 V seems very close to the stability threshold for my IMC/memory setup.

2100 FCLK / 1.28 V SoC

• Passed ~2h TM5 Extreme twice
• 0 errors
• 0 WHEA
• no thermal throttling

BIOS SoC override is 1.280 V.
HWiNFO shows CPU VDDCR_SOC Voltage (SVI3 TFN) ~1.285 V.

2133 FCLK / 1.28 V SoC

• Passed y-cruncher VT3 for 30 minutes
• WHEA clean
• TM5 Extreme eventually produced an error after roughly 1 hour 18 minutes

So 2133 is clearly not fully stable yet, but it looks fairly close.

Current Auto values from ZenTimings are approximately:

• VDDG CCD: 0.9496 V
• VDDG IOD: 0.9496 V
• CLDO VDDP: 1.0478 V
• VDD MISC: 1.100 V

I have not manually tuned VDDG yet.

I’ve also compared 2067 vs 2100 in CS2 and the gaming performance is effectively identical, so I’m not interested in pushing extra voltage just for benchmark numbers.

My goal is to see whether I can make 6400 1:1 + 2133 FCLK properly stable without doing anything excessive.

What would you try next?

1. FCLK VDCI Mode Pref P0 = Predictive first, with all voltages unchanged?
2. If that still fails, would you tune VDDG CCD/IOD next?
3. With Auto VDDG at ~0.95/0.95 V, what range would you personally test?
4. Would you keep SoC at 1.28 V, lower it, or increase it for 2133?
5. Is there anything else you would adjust before touching RAM timings?

My priority is daily stability and gaming performance, not benchmark screenshots.

I’m still fairly new to overclocking and memory/FCLK tuning, so I may be misunderstanding some things or making mistakes in my testing methodology or terminology.
If you notice anything I’m doing wrong, feel free to point it out I’m trying to learn and understand what actually matters instead of blindly copying settings.

Any results from people running 9800X3D/9850X3D + DDR5-6400 1:1 + 2133 FCLK or higher would be very helpful.

These are my current settings. It stays stable this way. Can I run it at 6200 MHz with this RAM and motherboard? What do I need to change?

Hey all, I have the aforementioned RAM (2x16), with sticker number 04213XS820C.

As far as my research told me, that's SK Hynix, C-die presumably? I really can't find any information on this. I've bolded the important last 5 digits of the number.

I would greatly appreciate if someone can tell me which Hynix die I have and what overclocks I can try. Currently, my RAM is running at 3200MHz, 1.35V with CL16-18-18-38 (XMP profile).

I upgrade to r7 5800x3d with gpu gigabyte 9070xt 16 gb. From the first day I install those to my pc I have crashes. Black screen sound stacked and restart. Before I change psu I got WHEA 18 events from event Viewer. After I changed psu to 1200w (found it on discount) I got crashes again when I enable PBO. I don't know why and I don't know if it's only when I open pbo or not.

Crashes are on gaming

I love these new free programs to tinker with however theres a few settings I'm a bit scared to touch in case my astral 5090 goes KaBoom!

I know my way around a few of them but wonder if its worth touching them if its really worthwhile (Such as when changing sys clock off set and video clock offset did not really show any performance boost for me when increasing them)

Are there certain generally safe numbers you can input into the settings like :

Core power limit

Xbar voltage offset

Sys voltage offset

Video voltage offset

Memory power limit

Hub control (SynVolt)

Or are they really just best to leave alone...

Thanks for any advice

Can someone tell me how to select good Mvolt settings for 5080? Anything I should know ahead of time?

Is there something very different about Mvolt than Afterburner I should know? Thank you!

GMTEK K8 PLUS - CPU BOOST CLOCK/s all running LOW

Not sure what setting has changed on my GMTEK K8+, but my CORE Boost is now not exceeding 3.7Ghz, even in a single CORE 'bench or stress test'. I don't recall changing any BIOS settings.. POWER is set to 'PERFORMANCE'. When I originally purchased it, & bench tested it with 3DMark, CineBench & GeekBench_7, it was getting much higher scores & CORE Clock frequency than it is currently.

Windows system 'CMD' indicates Power is set to 'Balanced' as does HWINFO64 (50% Balanced). There is no Thermal, Current or Power throttling on the CPU (via HWINFO64) - temps, even during 'bench' or 'Stress' tests don't exceed 50C.

Memory & iGPU temps are low. iGPU (780M) bench test maxes out @ 2700 Mhz - no Thermal or Power Throttle, just CURRENT.

Windows System Power Plan is = BALANCED (I can't set it higher) PPM is set to 5% = Minimum Processor state. 100% = Maximum Processor State.

I've tested it with Passmark 'Burn Test_11' complete range of 'bench & stability' tests.. which it passed. Max power draw on extreme test was 71KW, no thermal, power or current THROTTLING. Max Core Clocks were just above 3670Mhz & iGPU 2700Mhz. Core Temps never exceeded 74C - CPU fan was about 2800rpm.

K8+NUC = Operating System: Microsoft Windows 11 Professional (x64) Build 26200.9168 (25H2)

BIOS Version: NucBox K8 Plus 1.01 BIOS Release Date: 10/12/2024

System BIOS Version: 5.29

64GB Kingston HyperX DDR5 5600 / 2x Samsung 990Pro_1TB (2nd party heatsink) & 2TB version (Samsung heatsink). System fan replaced with 5V Noctua premium NF-A12x25 PWM, so very cool running.

Any ideas folks?

I have been working on overclocking my MSI 5070 TI ventus 3x OC with the new hydra software. I was previously utilizing MSI afterburner. I was hard locked at 300w (100%). Hydra allows me to push it up to 125% (more if you plan to do extreme cooling). I never went past 115% power in any of my testing. I found my max stable core was +425 and was previously at +375 in afterburner. Max memory that gave any meaningful results was +312 (around +2500 in afterburner). I stopped increasing xbar at +625 (as it was getting late and had to work today) even though it was still scaling appropriately. Probably could have scored higher and might test it out later this weekend along with potentially raising power limit to 120% these cards scale very well. My card is waterblocked.

Pic for attention

Only undervolted with -30 all core. PBO limits are off, tried the other options aswell and no change. Boosts to 5ghz~ so it all seems normal?

Feels like it’s in some sort of ECO mode even though it’s off. I have never ever seen it go higher than 60w stock or after undervolting.

Cinebench r23 - 18700 score but always capped to 60w, the score itself is good but still feels like it’s hard capped.

Gaming - 40-45w and FPS seems fine but I would want to know if I’m leaving performance on the table (if it’s somehow stuck in some power limit mode).

I’ve tried everything and maybe I’m just overthinking it but I thought I’d atleast ask if anyone have had the same ”problem”.

Is there any point messing with ram speed/timings

i have hardly any idea about overclocking but found out my ram on optimized defaults run 3200mhz 22-22-22-54-74 1,2V

sk hynix ram 2x 8gb

i was thinking of replacing it to 2x 16gb, but meanwhile before I do is there any realistic performance or input delay reduction from overclocking current ram

Gpu 3070 8gb

Cpu 5800x

i just dont want to break anything

Anyone have a working modded/higher-TGP vBIOS for the RTX 3050 in the Lenovo IdeaPad Gaming 3 15IAH7 (82S9 series)?

Running the laptop version with these exact specs from GPU-Z:

- GPU: RTX 3050 Laptop (GA107)

- Device ID: 10DE 25A2

- Subsystem ID: 17AA 3AF6

- Current VBIOS: 94.07.54.00.3F

- VRAM: 4GB GDDR6 (Hynix), 128-bit

- Boost clock: 1500 MHz (stock)

GPU's capped hard and throttling under load (Spider-Man 2, GPU pegged at 100% core load, hitting the power/thermal limiter). Tried looking for a modded vBIOS with a higher TGP a while back and came up empty, tried again recently and still no luck finding anything that matches this exact subsystem ID.

If anyone's got the same board (or something close enough - same GA107 chip, same VRAM config) and has a dumped/modded vBIOS that's confirmed working, I'd really appreciate a link or even just confirmation it exists somewhere. Also open to hearing if this is just a dead end on this specific model.

Happy to share my current stock vBIOS dump too if it helps anyone else on the same board.

I'm currently running a 4x8GB Samsung B-die kit at 3600MHz 14-14-14-30 (2T, GDM off, 1.50V) on AM4, and I'm looking for some advice from folks who have experience pushing a full 4-DIMM setup.

Since running all four slots puts a massive load on the memory controller and signal integrity compared to a 2-dimm setup, I wanted to ask y’all a few things:

- Sub-timing limits: What are realistic targets for secondary and tertiary timings when you're populating all four slots on Zen 3?

- T-Topology: For those who understand or have used T-Topology vs. Daisy Chain boards, how much does actual trace layout help mitigate signal degradation when squeezing tighter timings on 4 sticks, or is the CPU's IMC the limit anyway?

I’ll be happy to get any advices or feedback for my ram setup.

Setup:
• MSI B550 MPG GAMING PLUS
• RYZEN 7 5700X
• 4x8GB G.SKILL TRIDENT Z NEO (stock: 16-16-16-36 1.35v)

Been messing around with my 5090 and found something useful.

I had my memory at 18 GHz and Memtest Vulkan threw an error after like 11 minutes, so at first I thought the VRAM OC was the problem.

Retested with the same 18 GHz memory, but XBAR and SYS back at stock. It ran for an hour with no errors, even after the memory settled around 78C. I also put my normal 0.835V core profile back on and it was still fine.

Then I reapplied my +500 XBAR OC at 0.9V MSVDD and Memtest started throwing errors again after a couple minutes

So yeah, in my case it wasn't the memory at all. It was XBAR.

Seems like Memtest Vulkan is actually a really good way to catch unstable XBAR/MSVDD settings too

Might be worth trying if you're tuning XBAR on Blackwell. A “memory error” doesn't necessarily mean the GDDR7 is unstable.

Hi everyone. First, here are my current specs:

CPU: Ryzen 9 9850X3D
Motherboard: MSI X870E Tomahawk WiFi
RAM: TeamGroup T-Force Xtreem 2x24GB DDR5-8000 CL38
GPU: MSI RTX 5070 Ti Gaming Trio OC

I'm currently trying to improve my FPS lows in CS2. Using the CS2 FPS Benchmark map, I'm currently averaging 766 FPS AVG / 337 P1 across 15 runs.

I'd appreciate some help figuring out what else I could improve in my current CPU/RAM profile. After testing with TM5, OCCT, and y-cruncher, the current settings appear to be stable.

A few things I've already tried:

1. I can't boot with tRFC below 500.
2. I tried lowering tCL to 26, but I couldn't get it stable.
3. I also tried increasing the memory frequency to 6200 MT/s, but couldn't achieve stability.
4. If I enable Memory Context Restore, Nitro defaults to 2/3/1.

My main goal is to improve CS2 performance, especially FPS lows, rather than just chasing better synthetic benchmark numbers.

Any suggestions on timings, voltages, Nitro settings, FCLK, or other CPU/RAM tweaks worth testing would be greatly appreciated.

Settings

Vcore 1.1v under load (+45 Offset and 1.12v max)

Xbar +550Mhz +25Mv offset + MSVDD 1.035v max

Sys +440Mhz

~585w avg power draw

Suprisingly ive had 3362Mhz runs that scored 300pts less than this 3339Mhz run. i guess Xbar really makes a difference

i think 30k is possible with a good chip honestly

found the limit my loop can handle. prob gonna dial it back a bit. 🙊

I have a 3000MHz g.skill kit 2x16gb. I’m running 3200MHz CL16-19-18-38-56-480 1.36v with every other timing set to auto, I’m trying to get 3600MHz but it resets every time I boot into windows

So there is this MelonVolt app. This tool apperantly allows to set nvvdd which is core voltage iirc. my card is kinda a trash bin i wonder if I use a higher nvvdd range if it can help clock better or can this degrade the chip faster?? dont wanna risk anything in this economy xD
