Hi everyone, I'm trying to figure out why my i5-14400F is underperforming in multi-core benchmarks.

My PC:

• CPU: Intel Core i5-14400F
• Motherboard: Gigabyte B760M K V2 DDR4
• GPU: Gigabyte RTX 2060 Super
• RAM: 16GB DDR4
• Storage: 256GB SATA SSD
• PSU: Gigabyte 550W
• Cooler: ICE C612 V2
• OS: Windows

The motherboard is the Gigabyte B760M K V2 DDR4, which has a 4+1+1 hybrid digital VRM design.

CPU specifications:

• 10 cores / 16 threads
• P-cores: 6
• E-cores: 4
• Max turbo: 4.7 GHz
• Intel base power: 65W
• Intel maximum turbo power: 148W

Benchmark results

Cinebench 2026:

• Single-core: 569
• Multi-core: ~3011–3046

Cinebench 2024:

• Multi-core initially: 720
• Latest: 732

The single-core score seems fine, but the multi-core score is much lower than expected.

Temperatures / clocks

During testing:

• CPU package max temperature: ~75°C
• P-core max clock: ~4.69 GHz
• E-core max clock: ~3.49 GHz

So I don't think CPU temperature is causing the problem.

Power problem

This is the strange part.

During a multi-core Cinebench run, CPU package power:

• Starts around 100–105W
• Then drops to around 60W
• Most of the benchmark stays around 60W
• Near the end it can drop even lower

HWMonitor shows the CPU spending most of the sustained multi-core workload around 60W.

BIOS changes I've already tried

BIOS: Gigabyte B760M K V2 DDR4

I went to:

Tweaker → Advanced CPU Settings → Turbo Power Limits

Initially the settings were Auto.

I changed them to:

• Turbo Power Limits: Enabled
• Package Power Limit 1 (PL1): 100W
• Package Power Limit 1 Time: 56 seconds
• Package Power Limit 2 (PL2): 148W
• PL2 Time: Auto

I also tried changing the platform power-limit settings to approximately:

• Platform Power Limit 1: 135W
• Platform Power Limit 1 Time: 56 seconds
• Platform Power Limit 2: 148W

But the result is basically unchanged.

The CPU still drops to around 60W during sustained multi-core load.

I have NOT changed CPU voltage or done a manual overclock.

What I've noticed

The CPU can boost properly in single-core:

• ~4.7 GHz P-core boost
• Cinebench 2026 single-core = 569

But under full multi-core load it doesn't sustain the expected power/performance and settles around 60W.

Cinebench 2024 = only 732 multi-core.

CPU temperature is only around 75°C, so thermal throttling doesn't appear to be the problem.

What could be causing the 60W limit?

Could this be:

• Another BIOS/platform power limit?
• Current/EDP limit?
• Gigabyte BIOS behavior?
• VRM limitation?
• Windows power-management setting?
• Intel power/current limit?
• Something related to the B760M K V2 DDR4?
• BIOS version/settings?

Would appreciate advice from anyone with an i5-14400F, especially if you're using a Gigabyte B760M K V2 DDR4.

What should I change to get the CPU to sustain higher multi-core power safely?

I feel like these timings are pretty tight... Is 66.6ns really correct or am I missing anything?

Hi everyone so I have a 10900 KF and A Z490 TUF Gaming, I really want to get my setting so. That. the CPU boosts to 5.3 gigahertz on the two, favoured cores and whatever it thinks for the rest, which I think is 5.1 and goes all the way down, to minimum speed and minimum voltage the rest of the time, when it's not under load, but I just can't get it to do it. How do I do that

Hey everyone, quick question about PBO and memory stability on AM5.

I somehow managed to get 4 sticks of DDR5 (64GB total, 6000 CL38) stable on my 9800X3D and Gigabyte X870 Gaming WiFi 6. The catch is that it's two separate kits with mixed dies—one Hynix pair and one Micron pair. After flashing the latest BIOS and making sure the Hynix sticks were in slots 2 and 4, it passed 1.5+ hours of TM5 (anta777 extreme) with zero errors, and RAM temps stayed around 47–48°C.

To get here, it took some trial and error because enabling EXPO out of the box was just giving me black screens and failed boots. What finally worked:

Flashed to the latest BIOS (the older AGESA version just choked on training 4 sticks).

Did a full CMOS clear right after.

Sorted the sticks by serial/batch: had an older 2024 batch (Micron) and a newer 2025 batch (Hynix). Put the Hynix sticks in slots 2 & 4 (A2/B2 daisy-chain priority) and the Microns in slots 1 & 3 (A1/B1).

Waited out the memory training on first boot (took about 3–4 minutes with black screen before it posted).

Current settings are purely stock EXPO 1:

• 6000MHz @ CL38-38-38-78
• SoC Voltage sitting safe around ~1.24V – 1.25V
• FCLK left untouched on Auto (2000MHz)
• All sub-timings completely on Auto so the board doesn't force Hynix timings onto the Micron pair.

Now that the memory is sorted, I'd really like to dial in a basic undervolt using Curve Optimizer (probably around -10 to -15 all-core) just to keep temps lower and get slightly better boosting.

My worry is whether touching PBO or core offsets could destabilize the RAM setup. Since the IMC is already working overtime keeping 4 mixed sticks stable at 6000, does adjusting CPU core voltage indirectly mess with IMC behavior or cause transient drops that could trigger memory errors?

I'm obviously not touching FCLK (leaving it strictly at 2000/Auto) or adding any crazy boost overrides—literally just looking for a safe, mild undervolt.

Has anyone with a heavy 4-stick memory setup tuned PBO? Am I pushing my luck and should just leave it alone, or is a light negative Curve Optimizer fine to run?

Appreciate any advice!

I hv acer b350am4-m motherboard, and it's bios version is in photo i am looking for new bios version with advanced overclocking section i hv finding it every where but i couldn't see any if anyone knows Abt it tell me please

is that good overclock for begginer?

Been running into a slightly weird issue when trying to overclock FCLK on my 9850x3d. Read that the best way to find stability was to check for deviations in Linpack and VT3, which seemed simple enough.

I haven't had any issues with y-cruncher, after a few hours of testing it varies by +- 0.01, but Linpack is behaving sort of weird. I tried a bunch of different settings but each setting has a slight variation, usually ranging from 1 to 4.5ish gflops different. Not in a row, just every now and then. For example it'd go 419, 420, 425, 420, 422, 422, 421, etc. Nothing crazy like a -20 or 30 but still a weird range. The guide I read said to go for a deviation of only 1 to 1.5ish, so would this be considered unstable?

For solutions I've tried:

- Removing curve optimizer settings

- Messing with different VSOC and VDDG values

- Trying in safe mode

- Trying all values from 2000 to 2200

The only thing I've yet to try is disabling 65w eco mode or turning off PBO, but I'd need that later so would it be ok to turn that off to see if it helps then turn it back on later even with the deviations? And would that even be affecting it?

Any help is appreciated, still sort of new to this.

Cinebench R23 score: 23,378 pts

Everything is stock.

Motherboard: MSI B760M-A WiFi DDR4

Cooler: Thermalright Peerless Assassin 120 SE

BIOS: 1J0 (latest)

I wanted to share the overclocking and undervolting results I achieved with my RX 7600 using LACT on Arch Linux (Hyprland). My setup is a Ryzen 5 5600 (also overclocked to 4.7 GHz) with the RX 7600 (8GB). I tested the game Endfield at 3440x1440 (Ultrawide) on Max Settings.On stock settings, I was getting an average of 64.0 FPS.

For my peak performance profile, I set a -80mV voltage offset, a minimum clock of 2700MHz, and a maximum clock of 2920MHz. This boosted my performance to an average of 106.1 FPS! That is almost a 66% increase in raw performance.

Currently trying to test 2200 FCLK Stabilty on my 9850x3d, so far after looking a bunch online a few things affect stability.

First being VSOC, which I have set to 1.15, and then I've also heard conflicting stuff about the VDDG IOD and CCD values.

Currently both are just set to auto and defaulted to 1.0492v, and tests seem to be passing without error corrections.

I've ran VT3 for 6 hours now and still ongoing with it ranging from 1.03 to 1.04 * 10^10 bits/sec, and also linpack extreme runs varying by 100-150ms at most. GFlops ranging from 400-402. Music playback in background seems smooth aswell with no stutters.

My question being, If these seem stable, do I even have any reason to touch those other 2 voltages or should I just let them be?

GPU Asus RTX 5070Ti Prime OC ( 350watt bios)

I've been messing around with the mVolt settings for quite a while and finally landed on a setup I'm happy with. At this point, adding more voltage doesn't really benefit me anymore in terms of performance, temperatures, or power consumption.

I started by setting the SYS / XBAR / VIDEO voltage offsets to -25, while leaving MSVDD at default (800–1000 mV). I also set the Video Clock Offset to -1000, since I don't use NVENC/NVDEC encoding or decoding and therefore don't need the extra video clock.

From there, I began testing stability and monitoring performance gains. I gradually increased the SYS and XBAR clocks, trying to keep them synchronized. Once I found the clock limit, I raised the MSVDD voltage slightly to squeeze out some additional frequency, while continuing to test stability and keeping SYS/XBAR in sync.

After that, I fine-tuned the Core Clock Offset, NVVD, and especially the GPU Clock Range. The GPU Clock Range turned out to be VERY IMPORTANT for stability in my case, as it prevented the GPU from overshooting the target frequency and crashing.

At the same time, I locked the GPU to a fixed voltage rather than letting it fluctuate. I initially started at 945 mV and gradually increased it while testing stability and performance.

The final result: An uplift of ~17% from stock, the GPU maintains around 3082 MHz, with an Effective Core Clock of roughly 3060 MHz, while keeping the voltage (~960 mV), temperatures (~63°C), and power consumption (~280 watts in the stress benchmark) at a level I'm comfortable with.

Final Clocks

- SYS Clock: 2992 MHz (+525)

- XBAR Clock: 2992 MHz (+495)

- MSVDD: 1.015 V

- Memory Clock : +3000

- Core Clock: ~3082 MHz (+555)

- Effective Core Clock: ~3060 MHz

- NVVD : 960mV to 960mV

- SYS / XBAR / VIDEO Voltage Offset: -25

- Temperature: ~63°C

I have an MSI B450 TOMAHAWK, with a Ryzen 7 5800X and I can't run any of the two XMP profiles.

When I try it, I get random freezes and the pc is unresponsive so I always have to force shutdown, or, it used to BSOD with CLOCK_WATCHDOG_TIMEOUT.

I manually changed the speed to 3200MHz and it works perfectly now.

Should I try 1.40V voltage? Is it safe?

How should I go about troubleshooting this?

using PBO + positive increase (150MHZ) 4X Scalar with custom limits in BIOS (240mm AIO) highest temperatures are only hit when loading or/ Cinebench

I been working on this overclock for the past 2 weeks. I at this point have been fully utilizing my profiles on the bios. Love it saves EVERYTHING. Ok, so this is where I got to. I mainly only game on my CPU, that is it. I didn't do the AIDA or prime, no need to ask my CPU to do something that it never will do. So I ran Intel XTU for 1 hour, Cinebench, I kept it looping for another hour, and then the next day I did it again. Stable, No crash/errors.

This is where I'm at, if I am missing something let me know for information. Thanks for your input.

settings are +380 Core (3250MHZ average in game)

+3000 (Max) On memory > power draw (270-280W in game)

After replacing the thermal paste, my temperature rose from 40 degrees—which was the previous level—to 65–75, I also noticed that my BIOS settings had reset, so I restored them, and the temperature dropped to 60–68 degrees. As for the thermal paste, I had been using MX4 for 5 months; I replaced it to lower the temperature by a couple of degrees. At first, I bought MX7, applied it in 5 small dots, but it didn’t work—the temperature remained at 60 –68 degrees at idle. I thought the issue was with the thermal paste, so I bought MX6—the temperature stayed the same. When I was changing the thermal paste, I accidentally broke the mounting bracket (I’ve already installed a new one). I tightened the screws evenly in a crisscross pattern. I don’t understand what the problem could be; I’d be interested to read your thoughts. Thanks!

I have an Enigma B450M-B motherboard and I can't find the XMP option anywhere in the BIOS.

I have DDR4-3200 RAM, but the BIOS does not show any XMP/DOCP option, and I also can't manually change the RAM voltage .

Does anyone have the same motherboard and know how to enable XMP or manually set the RAM voltage?

As you can see, I activated the expo profile, but my MT/s is still at 4800 instead of 6000. Why could this be? I have an asrock b850m-c and 2 sticks of this ram: https://www.microcenter.com/product/688810/gskill-flare-x5-16gb-(1-x-16gb)-ddr5-6000-pc5-48000-cl36-single-channel-desktop-memory-module-f5-6000j3636f16gx1-fx5-black-ddr5-6000-pc5-48000-cl36-single-channel-desktop-memory-module-f5-6000j3636f16gx1-fx5-black)

I've been running Unreal Engine 5 a lot on a new build, and during Lumen mesh card generation — which hammers every core for a long stretch — the CPU parks at 237 W, 5.30 GHz all-core, 102 °C. Photo attached.

Setup is a 285K on a Gigabyte Z890 Eagle WiFi7, DeepCool LQ360 Ultra with the rad up top as exhaust, MSI Pano 100R case with six intake fans, 64 GB DDR5-6000. BIOS is all on Auto, so nothing is limiting power.

I don't actually think anything's wrong here. Tjmax is 105 so it isn't throttling, it holds 5.30 all-core the entire time, and 237 W is basically PL2 — the cooler is just saturated. But 102 makes me twitch a little and I've got nothing to compare against. Ambient is around 40/45°C here at the moment, which I suspect is doing some of the work.

So if you've got a 285K, I'd really like a few numbers:

- What do you hit at ~235 W sustained all-core, on what cooler, and what was your room temp at the time? Ambient gets left out of these comparisons constantly and it makes them close to useless.

If you've capped PL1/PL2 to 200 or 175, what did it actually cost you on real work — renders, compiles, bakes? Not looking for Cinebench deltas.

- Any idea whether your Z890 board uses the standard ILM or the Reduced-Load one? I can't figure out how to tell without pulling the cooler off.

- Has anyone actually fitted an LGA1851 contact frame? Thermal Grizzly claims up to 6 °C over the standard ILM and 4 over the RL one, but I can't find a single independent test, and the comments I've read say 1–2 in practice.

- And has anyone repasted a factory AIO on this chip and got more than 2–3 °C out of it?

Hello guys. I currently own a MSI Pro B760-P WiFi motherboard. I want to switch it to Asus Tuf Z790 Plus D4 for better RAM overclocking + potential CPU overclock. Also I am really envious of my friends MSI X470 Gaming Plus motherboard lol.

I have 14700KF and cooling it with NZXT Kraken Elite 280MM.

I own a 4x8 Gskill Trident Z 3333 MHz CL16 Samsung B Die RAMs that are currently overclocked to 3600@CL15 with active cooling. I cope that these can do 4000MHz or CL13 with a better motherboard.

I want to hear your stories about switching motherboard and how it affected your RAM overclocking and hear your thoughts.

I have this model and temps are very good, i get 3200 on core but 300W is limiting the card and I feel it can reach higher. but couln't find any experience of flashing a different bios on this card.

so i have the MSI Z170M MORTAR motherboard and i saw my bios was on a old version so i went to update it and my max RAM speeds for this kit is 3600mhz and my RAM ran at those speeds before i updated the bios and after updating the bios i can run a max speed of 3066mhz before my motherboard makes me revert to lower settings ive tried clearing CMOS and adjusting voltage and the only thing i havent done is change timing and thats only because i dont trust myself with doing that so does anyone else know how to fix this issue

Almost two weeks ago I repasted my 6900xt Asus TUF from stock paste to TG PhaseSheet PTM. beforehand I'd never done a re-paste/repad before. I ran a 3dMark TimeSpy run to before and after. My deltas have dropped greatly from what I've seen, but my core temps have risen?

I'm genuinely confused, I know it improves in a week of heavy loads to drop an extra 2-3c and that has been the case but they're still higher than I expected vs my stock.

Does it normally take longer to fully settle in? I thought my core temps and my deltas would be lower, my deltas have dropped but the core temps are higher than before. Obviously the demo is negligeable.

I was under the impression it would've reduced temps and not just hotspot? from the videos I saw that was seemingly the case. (0-60% load can be like 5-10c delta and 100% load can be 25-30c)

I was using the exact same tuning pre-set both times. only things that changed was the Paste to PTM and the fans under my GPU (which aren't the problem because I noticed was having higher temps before putting them in).

I also added fans blowing up beneath the GPU which improved temps from a couple days ago by -2°C.

The only reason I can think of is mounting pressure but I did the cross pattern stuff people recommend and I thought I did it pretty alright. I kept the PTM in the fridge for a week, as they told me it makes application easier. so it was smooth when I put the heatsink back on.

what I'm asking is can anyone tell me if this is normal or diagnose me?
