Outrageously high voltage [ 4295v ] on PCI Power Slot and 8 Pin #1 and #2

[valenceshell]

Hi,

I recently bought a 2080TI EVGA XC from ebay and so far so good. However, I'm seeing intermittent outrageously high voltage spikes recorded as 4295v only on the PCI Power Slot and 8 Pin #2 not 8 Pin #1. Also, randomly, all the Power settings in GPU-Z disappear and then reappear, with a empty white line when that happens between what it logged before and after. Is this a sign of a bad card or bad sensors or something else? I did unigine for an hour and no issues and played a few games, no issues. I previously ran a GTX 680 SC in there and never saw this behavior.

Any help would be greatly appreciated.

Thanks!



Correction, it also shows up on 8 Pin #1 too. It's also consistent, reporting the same 4295v value.

Adding some more screen shots.

I also tried this with newer and older versions of GPU-Z, same result.

It thinks it don't have ray tracing! LMFAO!

 

[thesmokingman]

You know its not real right??

 

[valenceshell]

It's also happening with HWinfo

It thinks it don't have ray tracing! LMFAO!

I noticed that too. Thanks.

You know its not real right??

Do you mean it's not a real 2080TI?

Please note, I'm using Windows 8.1 with this card with Nvidia Driver 411.70 based on this article: https://www.techpowerup.com/247985/...mption-tested-better-but-not-good-enough?cp=2

Could the driver be the issue with the voltage? As well as Win 8.1 (with not showing RTX enabled?)

You know its not real right??

I know that voltage can't be real, esp, when you look at the calculated wattage in HWinfo: 3156 watts. Do you think it's a sensor issue? Could that be a nvidia driver version/gpu-z issue with reporting or a failing sensor?

Ok, it looks like it's a driver issue. With nvidia 411.70, I get those anomalous spikes, with nvidia driver 441.41, it's as expected, all good. I have to assume (checking everywhere for the rare bird image of someone that made a post with Win 8.1 and a 2080TI screen shot, which I couldn't find, except for Win7 with a really old version of GPU-Z where it didn't even show RTX as even an option) that it's because Windows 10+ only supports it, not Win 8.1, so it won't show on GPU-Z as available. Going to let GPU-Z run overnight and then HWinfo overnight the next day and verify. But it shows up within minutes, and so far, it's been 2 hours and no spike.

Because it doesn't, OP is running Windows 8.1, which only supports DirectX 11.

If you must continue using 8.1 for some reason, install the latest driver supported which is 475.06. That glitch number btw - 4,294,967,295 is equivalent to 2³² - 1, the highest valid unsigned 32-bit integer number. I bet that the last 3 digits are interpreted by HWiNFO64 to be the millivolts and supports the first 7 digits as full volts or something.

Thanks for confirming, that makes sense. Actually, that was the first driver I used, but the minor version was 14, 475.14, which was buggy, my entire screen was pink and green. I tried 411.6x and then 411.70 which seemed to work (but with that voltage issue) and 441.41 seems perfect.

Thanks again, really appreciate it, the seller was willing to take it back, but it looks and runs fine for my old games (again, coming from a GTX680 SC, with a 10 year paid extra extended warranty that just expired when EVGA went out of the GPU business.)

 

[RJARRRPCGP]

Is that 32-bit 8.1?

 

[W1zzard]

These look like misreadings in the hardware or the driver. There is no reason for any concern, this is not an indication of a damaged graphics card

Thanks, it looks like it was the nvidia driver 411.70 that was the issue, using 441.41, it now doesn't do that with GPU-Z or HWInfo.

The only downside of this card I didn't realize is the idle power consumption for a single monitor 60hz hdmi connected, it's about 115% more than my EVGA 1080 on my other machine...the 1080 idles around 10.5 watts on average, this idles around 22 watts. I know this article is for the XC Ultra version, but if anything, I'd assume the Ultra would consume even more power, not less. The article suggest it's 11W on idle, which is true, if you only look at the GPU Core, if you look at the Board Power Draw, it's 22 watts. I assumed the article was referencing Board Power Draw as it matched perfectly for the 1080 on idle on the TPUI's article on that for idle power consumption.

EVGA GeForce RTX 2080 Ti XC Ultra 11 GB Review

EVGA's RTX 2080 Ti XC Ultra comes with a large triple-slot, dual-fan cooler and is overclocked out of the box. EVGA picked smart, balanced fan settings, making this one of the quietest RTX 2080 Ti cards we tested so far, and it comes with the wonderful idle-fan-stop feature, too.

Why not migrate/upgrade to Windows 10?

Any special reasons to want the very dead & obsolete Windows 8.1?

It is very possible this "issue" won't be there if using Windows 10.

Any special reasons to want the very dead & obsolete Windows 8.1?

Why is it obsolete? Because of collusion from MS/AMD/Intel and others purposely not supporting it, when most time it's just a driver string black listing the os when it would be fine to run on it? I prefer "dead," no more changes, everything you expect to work or don't is as-is. Nothing is taken away or added. I can do whatever I need to do with what an OS should be able to do. I can run VMware on it and use Windows 10 if I'm forced to. I can access the filesystem and run all my games and applications as I want without being spied on / forced fed updates and advertising on it thanks to Nadella. I already have a Kunbuntu machine with a dual 3080/3070 setup with gpu pass through for Win10 LTSC on a vlan when I absolutely must at this moment in time, hopefully that will change in the future and can completely get away from Microsoft, post Ballmer.

Drivers not the whole matter here.

Newer DX levels, newer (Intel mostly) hybrid CPU support, new kinds of GPU/display tech, newer (NVMe) SSDs support cannot work well or at all on Windows 8.1 (sometimes even Windows 10 too), but work fine on Windows 10/11.

RE Linux, don't use that so cannot comment much but this GPU pass through thing sounds nice.
Last time I checked, no way to use it on Windows OS hosts, only Linux (maybe macOS too, but no Macs here).

Maybe I can get a Linux VM software installed in the coming months on a dedicated PC.
( I would then mostly try to get macOS VMs running with GPU/3D acceleration, something I could not do on Windows 11/11 OS VM hosts. )

...this idles around 22 watts...

Higher amount of VRAM on the card is most likely reason for higher idle consumption and also bigger core than nvPascal of your GTX 1080.

Yep, that (3 GB more and maybe GDDR6 consumes more power,) the RT circuitry, the fancier RGB lighting (which I can't turn off just yet to check if that makes any difference,) and the USB-C (hovers around .6 watts.)

TU102 is the biggest processor die to make it into a consumer-grade product in recent memory, if I recall correctly, it's a 754 mm² beast. The 2080 Ti has some units disabled and only 11 chips of memory instead of the 24 used on the Titan RTX, so in a sense, it's still the "lite" version of this chip

Would never be an economy-class GPU, but for what it is, it could be a lot worse

Drivers kinda do matter. Let's say I build a new machine with excellent iommu groupings like the previous Gigabyte X570S Master. I'm now stuck with 6xxxx AMD and 2xxx nvidia cards going forward which will die out potentially in the years to come. Both have drivers for Win 8.1/7. So I can build a box with two gpus, one the latest, but one much older because let's say a game/app only works with 8.1/7, I'm stuck with those cards if even available anymore/working on the gpu passthrough due to drivers only supported there. I can't even use a AMD 7xxxx or nvda 3xxxx anymore because of a blacklist. They can easily allow it to work with 7/8.1...I know, eventually we have to let go, but for the time being, it's a artificial limit, not a real limit.

Please take a look at this if you're interested, I did what he did for my setup along with some help from level1tech forums.

Thanks, that makes sense, and this sums it up well: "but for what it is, it could be a lot worse"

I did get EVGA's Precision X to work with led sync (much older version I used to get it to work, pre-3xxx series, v1.0.7) and turned off the LED's, virtually, no wattage difference.

Sorry, bad wording on my part.
I did not mean drivers do not matter, they surely do.

I just meant drivers do not paint the whole picture of why you might want/not want Windows 8.1, 10 or 11.

Not all at all, nothing to be sorry about, I completely understand.

It looks like this maybe the last driver for Windows 7/8.1 for the Nvidia 3000 series and NONE for the 4xxxx series.

I don't think AMD for the 7xxx has any support for Win7/8.1

Would be nice if they did, as some games I still play from that work great on Win7/8.1, like Battle Field 2 (2005) with Allied Intent maps which you can't get anymore and Oblivion and Skyrim -- the 4xxx series could extend the life of those games if they no longer work with newer versions of Windows or Linux (haven't tried with either, other than my VMs with Win7/8.1 and dedicated Win 8.1 / 7 machines) by being able to use a jailed vm with win7/8.1 and gpu passthrough.

Windows 7 is obsolete. Anyone who wants to run Windows 7 for whatever reason doesn't need an Ada Lovelace or RDNA 3 GPU, they'll perfectly do okay with earlier generation hardware. The OS doesn't support anything that these cards can do.

I meant for the next 10 years, as say the GTX1xxxx and 2xxxx will probably physically die out, but at least the 3xxxx series can carry it for another 10. If the 4xxxx included it, it could've carried for a possible additional 2 years.

If you are that badly against modern versions of Windows, the correct answer is to move to Linux and virtualize older versions of Windows, especially now that VMware Workstation is free.

Did you read my WHOLE post?

 

[Dr. Dro]

Did you read my WHOLE post?

Yes. The whole idea is that you shouldn't expect driver support just because it could carry something you should not be using in the first place another decade. It's what it is... be happy that an OS as old as 7 was supported this far into the future.

I understand how you feel, I would use Vista to this day if it worked on my hardware. What did I do, though? I got an old computer to run it on.

You can get vista to run with qemu in linux and passthrough the gpu to that vm, but you'd need a driver for a gpu that has vista drivers, like the 8800GT https://www.nvidia.com/download/driverResults.aspx/99994/en-us/ -- I still have a working PNY 8800GT. Or use vmware workstation just for old apps, not games, I have lot's of vm's from Win3.1 to Server 2019, but they are not using gpu passthrough. For the 4xxx series, there's no real reason that I know off to block Win7 or 8.1 on the 4xxx series drivers, it's not much different than the 3xxx series. I know what you're saying, and I'll leave this as-is, and thank you for your original help on this regarding the erroneous voltage logging.
