NVIDIA RTX 50 SERIES - Technical/General Discussion

5080 is the modern day equivalent to a 3060ti/3070 although it’s not a budget card.

Really? What was the TDP of a 3060 ti and 3070?

Just because the top end GPU is now a 600W beast, doesn't mean everything has to double in power.

If the 6090ti comes out requiring 800W with a million SMs, doesn't mean the core market is now suddenly at 500W GPUs.
 
I recently encountered an unusual issue with my MSI 5080 Ventus graphics card, which now appears to be resolved. I wanted to share my experience in case others face a similar problem.

After installing the latest NVIDIA driver, the GPU fans became excessively loud, seemingly running at full speed.

Upon inspection, fans 1 and 3 were spinning, but fan 2 remained stationary.

Monitoring tools like Fan Control (FC) and Afterburner indicated a fan speed of 30%, which didn’t align with the noise level.

Under load, FC reported increased fan speeds corresponding to rising temperatures, but fan 2 still did not spin at all.

I removed the fans from the GPU and gently wiggled and the wiring connections.

After reseating the fans, I recalibrated the sensors and fans using Fan Control, the fans were the same before I recalibrated ( worth noting I tried this several times before taking the steps above)

Post-calibration, all fans began spinning quietly, including fan 2.

It appears likely that adjusting the fan connectors resolved the issue although I suppose it could have been a coincidence

Secondly, the 5080 not equivalent to a 3060ti/3070, unless you want to bring in the utterly meaningless metric of % of the full die used.

Clearly the size of die is relevant, even if we look at the performance then you will see the 3070 was closer to a 3090 than a 5080 is to a 5090 so its obvious to anyone that its the same class of GPU.

But it’s totally, totally meaningless to compare across gens like this :o It has no bearing on performance.

If all gens to date had the same uplifts except the 5000 series, and the 5090 was literally a billion times more powerful than the 4090… would the die % of the 5080 matter…? No… it would still be hundreds of millions times better than the 4090.

Or put the other way, if the 5090 was less powerful than a 4090, but the 5080 was a record breaking 99% of the 5090 die… this wouldn’t make the 5080 a better card, would it?

Or the fact he had everything crammed into an SFF which would expose the connector to more heat in general and perhaps bring about a failure more readily than in a system with better airflow.

That we don't know, They certainly shouldn't be bent I know that, That's up to the user to use some common sense.

The changes were to maximise the chances of the cable being ‘plugged in properly’, because it not being plugged in properly = potential issues.

Saying “but if it’s plugged in properly it’s fine” is sort of ignoring the purpose / reason for the change.

I know, That's my point about it being marketing spiel, It's not a thermal design change at all, Everything about the rating and capacity is exactly the same as it is still down to the user to plug it in properly and use a decent cable however with the 5090 things could be different because of the higher wattage.
 
I've experienced 1 bluescreen and 2 mysterious black screen then auto restarts of my system since installing the latest Nvidia drivers. This is on my 3090. Have DDU'd and reinstalled so hoping that fixes it. WTF did they do with the latest drivers?

Of course it’s not meaningless, comparing performance gen on gen is the measure of progress while comparing performance metrics between cards of the same gen shows how the performance of each tier stacks up against what is historically expected of that class.

In both cases the 5080 is an outlier as it’s the first 80 class card not to beat the previous gen flagship while also the gap between it and the current flagship is by far the largest ever seen.

This latest driver is awful on my 5080. SteamVR is broken with unplayable frame drops and spikes with various headsets, but works great with my old Reverb G2. I'm also getting random odd pauses/ freezes on desktop for about 5 seconds.
Was running the same drivers on my 3090 and they were flawless. There's deffo some bugs to iron out

I've not had any bluescreens, though I've not been playing anything that uses framegen (which seems to be a common trigger), just FF7 Rebirth and Mechwarrior 5 Mercs. I did have a weird thing when I first installed it where having Discord on-screen would cause rapid black-screen cycling. Weirdly, turning G-Sync on and off again solved it.

The driver is not good. I've gone back to the previous one and plan on staying there until we either get a "good" new driver or my 5090 arrives.
