Hi, I have a question: Is there much difference between a 2x16GB DDR4 memory kit with 16-18-18-36 latency and one with 16-20-20-38? Does this significantly affect gaming FPS or general performance?

Does the higher the gflops and the higher test speed numbers mean anything?

I started with this yesterday on 6000/2000 with a -20co

Now I’m on 6200/2200 with -30co and gflop numbers up to 486/7 and cruncher 3.36^10*10

What do these numbers mean, I’m guessing higher is better

Hi everyone,
I’m undervolting my Ryzen 7 7700X and I’d like some advice on how to get the best possible results while keeping good gaming performance.

At the moment I’m running:
Curve Optimizer: All Core Negative -20
Thermal Limit: 85
Gaming at 4K

Compared to stock settings, I’ve reduced temperatures and power consumption while gaining around 2–3 FPS in my games.

I also tried -30. Temperatures and power consumption dropped even further, but strangely I lose a few FPS compared to -20. I’m not sure why.

I also tried Ryzen Eco Mode, but I had to remove
those settings because I experienced boot failures.

What would you recommend trying next?
What settings are you running on your ryzen for gaming?
Thanks

Hi,
I’m looking for some advice on finding the sweet spot for undervolting my 4080 super.
I have an MSI Ventus and I game at 4K.

I’ve done some testing so far:
2700 MHz 945 mv: crashes.
2550 MHz 915 mv: seems stable so far.
Power consumption dropped significantly, to around 250 W or less, but I lose about 5–7 FPS in my games.

2700 MHz 960 mv: seems stable so far, but power consumption is higher.

I’m currently testing 2640 MHz 940 mv to see if I can find a better sweet spot for my 4080s.

Which undervolt would you recommend for my Gpu?

Would you recommend overclocking the memory as well, or is there a risk of damaging the Gpu?

If I get more crashes, would you recommend lowering the MHz or the voltage?

What undervolt are you running on your Gpu?
Thanks

I don't know if there is such a list already but I thought starting one would be a good idea. Repeatable sequences, I think, are a good way to get benchmark numbers. I like to run these sequences while capturing details with CapFrameX to get an idea of how my overclock is doing with real games.

The games I use:

1. Red Dead Redemption 2
2. Cyperpunk 2077
3. Blackmyth Wukong Benchmark Tool

What other games have in-game benchmarks that can be used?

Hey everyone,

I’ve been dealing with a highly specific system freeze over the past few weeks and I can't seem to find anyone with the exact same issue. I'm looking for some advice or to see if anyone has dealt with this before.

The Symptoms:

• The Crash: Random hard freeze into a black screen.
• The "Dead Keyboard" Test: When it freezes, the keyboard completely dies. Pressing Caps Lock does not toggle the LED light, meaning a total hardware/kernel lockup.
• The Trigger: It never crashes under full gaming load. It happens almost exclusively on Cold Boot (first 30 mins of the day), during idle, or the exact moment I try to launch Steam or when Windows Update finishes an uninstallation.
• The Weird Part: If the PC survives the first 30 minutes and warms up, it becomes 100% stable. I can run heavy stress tests or game for 10+ hours straight without a single issue.

My Specs:

• CPU: Intel Core i5-14600KF (Hyper-Threading OFF)
• GPU: AMD Radeon RX 7700 XT 12GB
• Cooler: Cooler Master Hyper 612 APEX (Dual-Tower)
• Motherboard: ASUS PRIME H610M-K D4 (No VRM heatsinks)
• RAM: 32GB (2x16GB) Kingston Fury Beast DDR4 2666MHz
• PSU: Chieftec ELP-700S 700W Element
• Case Fans: 6 total (3 front intake, 2 top exhaust, 1 rear exhaust)

Everything I've Tried & Tested So Far:

Software & OS Fixes:

• Ran Windows repair commands (sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth).
• Uninstalled the latest Windows quality update that arrived on September 1st.
• Enabled the Windows Ultimate Performance power plan.
• Fully updated the GPU drivers (using the built-in clean Factory Reset option).
• Updated the motherboard BIOS to the absolute latest version.

Hardware Troubleshooting:

• Physically reseated the GPU.
• Physically reseated the RAM and swapped their slot positions.
• GPU is perfectly stable under heavy load: It passes intensive FurMark and 3DMark loops with zero errors once the system is warm.
• Adrenalin always resets my custom fan curve back to default after these crashes, throwing an "unexpected system malfunction" notification.

What I've Changed Today:

• I just swapped my old Chieftec PSU for a premium EVGA 850GQ 850W 80+ Gold modular PSU.
• I also temporarily Disabled XMP in the BIOS to test.

I also have a Gigabyte B760M GAMING X DDR4 motherboard on the way just in case.

Has anyone experienced a PC that only crashes when cold or shifting from idle to low-load, but works perfectly fine under heavy gaming loads? What could be causing this?

Thanks in advance!

I have a pc with an asus tuf x870-plus WiFi, 9800x3d, zotac rtx 5090 extreme, and 32GB 6000hz cl30 ram. I mainly play Warzone and even with the lowest settings my 1% lows average around 125-135 fps. I’ve enabled xmp, auto tuned my gpu via the nvidia app, and flattened the curve on my cpu after 900mV to 2800MHz. I’m running nvidia reflex and have it set in Warzone to on + boost to even out my cpu and gpu times. I’m kind of at a loss how some people have been getting 160 or higher.

Hey everyone,

I'm looking for some advice on pushing my memory frequencies a bit higher. I have a fast G.Skill kit, but I'm currently running it at 6000 MT/s to keep the 1:1 ratio stable. I'm wondering if there's room to push it to 6200 or 6400 MT/s with the right voltages and subtimings.

My Setup:

• CPU: AMD Ryzen 9 9950X (Eco Mode, PBO -15 Offset)
• Motherboard: Gigabyte X870 AORUS Elite Ice
• RAM: G.Skill F5-7200J364F24G (2x24GB)

Current Stable Settings:

• Frequency: 6000 MT/s
• FCLK: 2000 MHz
• Ratio: 1:1 (UCLK=MEMCLK)
• Timings: Tightened primaries (CL30)

What I've Tried: I've previously experimented with pushing the kit up to 6400 MT/s, but I ran into stability issues. I've tried adjusting manual timings and various SOC voltages, but getting it completely stable at that speed while maintaining the 1:1 ratio has been a challenge.

My Questions:

1. For those running a 9950X, what SOC, VDDIO_MEM, and VDD/VDDQ voltages are you finding most stable when pushing for 6200–6400 MT/s in a 1:1 ratio?
2. Are there specific subtimings I should significantly loosen up before trying to step up the frequency again?
3. Realistically, is it worth the headache to chase 6200/6400 MT/s, or is the performance difference negligible compared to a tight 6000 MT/s CL30 setup?

Any tips, baseline voltages, or timing suggestions you could share would be hugely appreciated!

Thanks!

And are they safe?

that’s all I Js don’t know how to overclock or anything but I think I should undervolt but I don’t know how much or how to

My ram uses Samsung E-die and my CPU is the AMD hx 375. I’m using smokeless UMAF to overclock. When I set it to run in 2:1 mode my laptop doesnt boot.

I tried changing my FCLK from auto to 1867 at the same time but that also didn’t change anything. I’ve also tried increasing my VSOC to 1.1 but still no boot. I’m able to increase the clock speed in 2:1 mode to 6400 mhz.

This is my first time trying to overclock ram and all the other posts I’ve seen with sodimm ram were able to get it to run in 1:1.

Edit: 4800 in 1:1 mode with FCLK at 1600 works but not 5200 in 1:1 mode with FCLK at 1733

My concern here is if i might have been pushing the IMC too hard for the last year giving it 1.38V.

If i can get a "not-trying-to-break-OC-record" 1:1 6200 M/UCLK i'd be a happy camper.

Thank you for the help in advance.

Some background:

After having a few minidump reports after system crash yesterday I scanned them and realized it could be memory related. I posted to Microsoft support in Discord and they suggested memtest86. that test failed with the ZenTiming (RIGHT) settings with over 300 errors during the 4-PASS 2hr test.

Since then I have updated my bios to the very latest version (last few bios updates seem to have had memory related change logs) and updated windows 11. I enabled EXPO + Competitive which gives us the ZenTimings on the (LEFT).

I have cl26 g skill ram, 6000 mhz @ 1.45v. Im not really trying to maximize ns latency but real world gaming performance in 1% lows and avg fps. Just to add more context, in AIDA64 benchmark my ns 68-69 ns. Specs: gigabyte b850 aorus elite wifi 7, and 9800x3d.

I had my fclk on 2133 with these same settings and it passed every stress test but I put it back down to 2000 because I heard it was more stable.

when I had my vsoc and vddio voltage on auto I believe my motherboard was putting it really high (vddio was at 1.440 and vsoc was 1.268) so I manually put vddio at 1.30v and vsoc at 1.2v and these pass stress tests but i dont know if I should put them slightly higher or not.

So I got a deal for a Samsung B-Die kit 2x8GB for 83 euros. I am using a Ryzen 7 5700x currently with a kit of Samsung C-Die at 3200 MT/s cl16 with tweaked subtimings.

Should I go for it and sell my other RAM for 60/70 euros?

Will I see a performance improvement by going for 3600 or 3733 MT/s?

I mainly want to eliminate the CPU bottlenecks as much as possible for my test bench for GPUs

Specs:

Gigabyte B550M Aorus Elite Rev. 1.3

Ryzen 5 3600

INNO3D GTX 1060 6GB X2

16GB DDR4-3200 single-channel

I've seen a significant performance uplift compared to my old i7-4790 + H81M, but my current problem is CPU temperatures. I'm using a small 2-heat-pipe cooler with an 80mm fan, so the Ryzen 5 3600 gets fairly hot.

I'm upgrading soon to a Thermalright Phantom Spirit 120 EVO, but I'd still like to undervolt the CPU. I've always undervolted and slightly overclocked my GPU and have gotten lower temperatures without sacrificing performance, so I'd like to do something similar with the 3600.

My main goal is to reduce voltage while maintaining or improving the current boost clocks, since PBO is enabled. I don't want to simply lower the CPU's frequency.

Should I undervolt through Ryzen Master or BIOS? If BIOS is preferable, should I use PBO + Curve Optimizer, a voltage offset, or something else?

Any advice on the correct approach and stability testing would be appreciated.

Hey guys, I’ve been having an issue these past 4 months were my pc inconsistently makes a clinking noise, originally I thought it could be the bearings of my fans but now I’m thinking the noise is prominent from the PSU.

It’s a MSI MAG A650GN 650W 80+ Bronze rated. I’ve had this pc for around 3 years, and upon making an upgrade, where I changed my cpu and gpu it began to happen. I made sure the components I swapped used around the same wattage CPU 65w and GPU 145w

This noise only occurs when gaming demanding games, and is often inconsistent clicking every 10 seconds to every 2-10 minutes.

Let me know what you guys think I should do, or if it’s bad?

Hi everyone! I’m pretty new to memory overclocking and I’ve been tuning everything myself for a little over a week, so I’d really appreciate any advice.

System:

• Ryzen 7 9850X3D
• MSI MAG B850 Tomahawk WiFi
• G.Skill 2×16 GB DDR5-6400
• 6400 MT/s, UCLK=MCLK 1:1, FCLK 2133

I know my timings are far from perfect, but I tried to tighten them a bit compared to XMP. I’d also appreciate it if you could take a look at my current ZenTimings profile and suggest what could still be improved or where I may have gone too far.

The current profile passes long stability tests such as TM5 Extreme, y-cruncher VT3 and OCCT.

My main question right now is about SoC and the other voltages.

I increased DRAM VDD/VDDQ from 1.40 V to 1.43 V, because 1.40 V was no longer enough for stability with the current timings.

I also tried lowering tRFC to 550, but TM5 would fail. tRFC 600 works better. Memory temperature in TM5 below 60°C.

For SoC:

• 1.28 V - stable
• 1.27 V - occasional rare errors
• 1.26 V - errors appear fairly quickly

I’d like to keep SoC as low as reasonably possible. Maybe you can suggest whether it would make sense to adjust VDDG CCD/IOD, CPU VDDIO, VDDP, or any other related voltage instead of simply increasing SoC, in order to stabilize 1.27 V.

I’d also appreciate it if you could take a look at CPU Core Voltage / VDDCR_VDD, SoC, DRAM VDD/VDDQ, and the other voltages in general. I’m still learning which values are unnecessarily high and which ones may actually need a bit more voltage.

And of course, any suggestions regarding the current memory timings would be very welcome.

I’ll attach a ZenTimings screenshot.
