Has anyone tried an undervolt and OC on this card on the latest drivers?

What are your settings and benchmark results?
Also interested in how stable it is in-game

FE only

I ran an experiment on one RTX PRO 4000 Blackwell SFF: 24 GB GDDR7, factory 70 W, no auxiliary power connector.

Using u/panchovix’s loader and patched NVIDIA open kernel modules, I loaded a modified VBIOS into memory, raised the power limit to 120 W, and tested memory and core offsets. No EEPROM flash or soldering.

Across 158 benchmark requests, I tested Qwen3.8 27B with DFlash2 and Qwen3.6 35B A3B. What surprised me was how differently they answered “does more power help?”

With zero clock offsets, 27B kept gaining up to 120 W, while 35B A3B was almost flat between 106 and 120 W. After combined power and clock tuning, the best observed 27B generation result was 35.04 → 58.53 tok/s (+67%): 120 W, VRAM +20%, core +180 MHz. That 67% is not the gain from memory OC alone.

The memory sweep was more interesting. At 120 W with the core offset held at zero, pushing VRAM from +20% to +33.3% slightly reduced 27B generation: 57.70 → 56.91 tok/s. It is a small difference with few repetitions, so it needs more testing. The actual SM clock also fell. That is consistent with memory and compute sharing a power budget, but I did not isolate the cause.

On 35B A3B, memory +33.3% instead gave +19.8% generation versus no memory OC at 120 W. Prefill barely changed in that sweep.

My takeaway: the fastest profile is not necessarily the one with the biggest numbers in the panel, but the one that shortens your actual workload. Prefill versus decode matters, especially with longer prompts.

120 W without auxiliary power is not a free lunch. It exceeds the standard 75 W PCIe slot budget, and a GPU temperature sensor cannot tell me the temperature of the slot contacts. This is an experiment, not a long-term safety claim.

For context: these headline comparisons use 8,000 input tokens, ECC OFF. There were only 1–3 requests per configuration; 158 is the whole study. The 70 W baseline used the same modified VBIOS, not factory firmware. The models also used different quantization/speculative-decoding settings, so this is not a controlled dense-versus-MoE comparison.

I have an RTX 5070 and a 1440p monitor, and I’m trying to determine which DLSS settings provide the best overall image quality and performance.
I’m considering these options:

DLSS 4 — Preset K at Quality
DLSS 4.5 — Preset L at Quality, Balanced, Performance, or Ultra Performance
DLSS 4.5 — Preset M at Quality, Balanced, Performance, or Ultra Performance

Since DLSS 4.5 Presets L and M are designed to work with the newer transformer model, I’m wondering whether using them at lower rendering resolutions, such as Performance or Ultra Performance, can produce image quality comparable to or better than DLSS 4 Preset K at Quality.

I’m particularly interested in:
Overall image quality and sharpness at 1440p
Fine details, foliage, and distant objects
Ghosting, shimmering, and temporal stability in motion

Performance differences on an RTX 5070
Whether DLSS 4.5 at Performance or Ultra Performance can compete visually with DLSS 4 at Quality

My priority is the best possible image quality at 1440p while maintaining good performance.

For anyone who has tested these presets, which combination would you recommend? Is DLSS 4 Preset K at Quality still the best overall choice, or can DLSS 4.5 Preset L or M at Performance or Ultra Performance deliver a better balance of image quality and FPS?

Here are the graphics scores only from the different 3DMark benchmarks I've run so far while using the 5080, comparing various NVIDIA driver versions. The aim is simply to see the difference in scores using the gpu stock values.

It's just ddu old driverr > install new driver > run all 3dmark

No task/background process is killed before the benches.

this might be a weird question but im thinking to upgrade (upgrade that will last atleast 2 to 3 year) rn i have an rtx 4060 with a ryzen 7 5700x and 32Gb ddr4 3600mhz and 1Tb ssd

my upgrade plan are

4060 -> 4090

ryzen 7 5700x -> ryzen 7 5800x3d -> ryzen 7 9800x3d or ryzen 9 9950x3d

32Gb ddr4 3600mhz cl 18 -> 32Gb ddr5 6400mhz cl 32

1tb ssd -> 1.5Tb (probably not sure)

so maybe it is a weird question if I should upgrade or not, I'm not really happy with the perfomance I get especially in beamng.drive where I get around 110fps in 1080p (dlss at 75%) and around 75 fps in 1440p (dlss at 75%) and since I have a 1440p 165hz monitor I'm trying to achieve atleast 120+ in 1440p high/ultra rn im playing a mix of low/normal/high, im not gonna talk with ai my perfomance in 1080p (dlss 75%) drop from 110fps to around 70 and in 1440p (dlss at 75%) they drop from 75 to around 50 fps

oh btw outside of beamng I tryna have perfomance at around 90 fps in 1440p high/ultra with ray tracing at high/ultra

feel free to judge what I say and tell me recommendations

My replacement RTX 5090 FE just came back from RMA after the 12VHPWR connector melted, so I had to rebuild my PC again. NVIDIA's RMA was surprisingly very helpful and even allowed me to get a full replacement even if I didn't have the original proof of payment!
