NVIDIA RTX 50 SERIES - Technical/General Discussion

Having a couple of issues with my Zotac card. I think I've resolved one which was a cold boot issue, where the fans would spin up but the system wouldn't post without turning the PSU off for 10+ seconds before booting up again. It used to happen on occasion with my 6800XT so I reset the BIOS and only enabled XMP and ReBAR which seems to have done the trick.

The other is odd performance in Darktide and Helldivers. The latter was a stuttery mess on occasion with my last cards but that could be resolved by a restart, however now despite a good frame rate in both games they just aren't smooth at all, with a juddering that makes them feel like they're running a lot slower than they are. The GPU usage is fairly low (60-80% in DT IIRC) which indicates a CPU bottleneck, but with the framerate (always over 100) it should feel smoother than it does, and I didn't have this with the 6800XT.

For comparison I loaded up Insurgency Sandstorm and locked it to 120FPS and it was as expected, then did the same in DT and it feels far worse. FG is off. It may be that I need to do a reformat which I hoped to avoid, but other games run fine (GOW Ragnarok, Halo Infinite, all VR games). Also lowering settings to the lowest didn't really help much.

I'll try clearing my shader cache again tonight, but any other suggestions would be appreciated.
From experience - make sure you didn't make any changes in Nvidia app regarding global settings for graphics. Especially don't touch the low latency settings and try again. In my case this was completely killing fg and causing issues in many games. If not that, you might need to reinstall your os or at least run ddu first to be sure nothing is left over from old GPU.

My post you quoted was about the gap between the 5080 and 5090 and them making a card inbetween. My point was they would need to use the GB202 die to do so because GB203 is already maxed out on the 5080.
And my point was that the GB203 die should not be called a GB203 die, that it should be called a GB204.
 
Has anyone else had the PCIe Gen 5 issue with a non-FE card? I installed my Palit card yesterday and found stuttering in Windows. Assumed it was a quirk of first boot, so I clean reinstalled the drivers, rebooted, and the problem went away. Yippee! However, I came to my PC this morning and the stuttering was back. I ran Indiana Jones which immediately hard-locked my system. Having read about the FE issues, I changed my PCIe slot to Gen4 and was able to run with zero stuttering or crashes. My 3DMark score even came out slightly improved (albeit by, like, 0.8%).

I have only read sporadic reports from randoms on Reddit etc. about third party cards having this issue also, and wondered what people here may have experienced.

Interesting - what’s your motherboard / BIOS revision?

I can’t imagine why the PCIe stuttering wouldn’t affect AIBs as well as FE cards, it’s the same underlying systems/drivers.

I’m fairly certain I read of someone using an MSI card and others getting these PCIe issues on Reddit.

Palit RTX5080 here and had no issues with any PCIe issues on Gen 5. I know that this probably isn't hugely helpful in understanding the problem.
 
After spending almost a week with the 5080, the card is nowhere near as bad as the reviews are making out, and a huge upgrade over the 3070. Performance in some tests like Steel Nomad has it at 30% faster than the 4080 super so perhaps a sign of things to come. I think this could be a Nvidia fine wine situation.
I'm only a couple of days in with mine, but subjectively it feels pretty good. I'd kinda expected that, coming form a 30 series, it would feel like a big jump - but it does feel like a huge upgrade to me. I'm still at the early stages of overclocking it, but I spent a couple of hours playing CP2077 last night, and it held stable with a 300Mhz OC, which according to the benchmark gained me about 10% extra fps with all the RT/PT goodies turned on.

But I also quite liked the experience with 2x Fakeframes turned on, so my subjective judgement may differ from others preferences.

I think the issue is how the PCB is connected to the connector. On the 5090 FE it uses a connector similar to a riser. My friend had a SFF case and had no end of issues with PCIe gen 4 risers at that time so I think it could be along those lines. The AIB's are more conventional PCB directly connected to the connector so there shouldn't really be issues, other than motherboard BIOS issues relating to a new tech. However even the AIB issue could just be BIOS issues as well they don't really know yet.

This was my logic exactly - I didn't see why the third party ones wouldn't have the issue also, but all I was reading 99.9% of the time was issues with the FE cards.

MSI X870 Tomahawk WiFi, I am running BIOS 7E51v1A16. Was tempted to update to 7E51v1A24 but up until now haven't really had any reason to do so.

I should add that there is a little bit of doubt with my situation. There was a point last night where I rebooted and didn't have the issue, so I am paranoid that my success this morning after dropping the PCIe Generation down to 4 was just me getting a 'lucky boot' so-to-speak. I wasn't able to test extensively beyond this before I had to leave for work.

Isn't the suspicion the riser boards used by the FE's?

I have the X870 Tomahawk Wifi also using BIOS 7E51v1A2, I didn't update to the newest yet because of the reported issues with USB. I have the MSI Ventus 3X and it's running in PCIe Gen 5 mode. So far I haven't noticed any issues with stuttering so perhaps try DDU and reinstall Graphics and chipset drivers to see if it helps. If you have an X3d MSI recommends using the latest AMD chipset drivers.

I thought the issue was that it isn't enough of an uplift over the 4080 (Super). I imagine if you upgraded to a 4080 card you'd be happy with a similar "huge upgrade" over the 3070.

Yes, I've got the latest Chipset drivers on. I'll try DDU if the problem reoccurs. To be honest, if it remains stable at PCIe Gen 4 I don't really have a reason to swap back as far as I can tell.
 
@SuperJoe it’s worth upgrading to the latest bios - even just to eliminate that as an issue. Save / take a camera snap of your ram settings etc first, as they will probably be wiped.

Hope you get it sorted mate.
 
Is there any chance it could be my power supply being insufficient? NVIDIA recommends a minimum of an 850w PSU, which I have, but I'm also rocking a 9800X3D, two SATA drives, two NVMes and a sound card (yes, in 2025.) Slightly ignorant on the power supply side of things, but fortunately I'm not afraid to show my ignorance.
