Random reboots during gaming after upgrading to RX7900XT

[heatonpkmassive]

An OEM is going to install a thermal paste that lasts the length of the cards warranty, keeps the card within spec at a certain price point which is why as you say people can go many years without repasting.

But that doesn't mean there isn't a performance uplift to be gained from replacing the OEM paste with a TIM better thermal properties. It's the same reason people buy a GPU then slap a water block on it.

No I agree with that, you can certainly gain performance by repasting in some cases. On your 3080, Dell being Dell will only give you something that is sufficient and I'd expect you can improve on that by applying better quality paste and applying it in a better way than Dell or their OEM would give you, as you have done.

I wouldn't expect to repaste this 4080s FE for at least 3 years and likewise for the 3080 FE that preceded it though.

Other forums and various YouTube vids suggest switching to Kyrosheet on RX7900 GPU’s reduces the difference between the GPU temp and hotspot so why not give it a try?

It isn't something I'd ever recommend someone attempt, unless the card had obvious thermal issues or was particularly old.

Plus, even if it did have thermal issues within 2 years is really an RMA job (because the cooler is likely faulty, like the bad batch of reference 7900 XTX with the vapor chamber issue).

There's a lot that can go wrong when taking coolers off, because they're not meant to be end-user maintainable and aren't very user friendly, with screws everywhere, custom pads and fiddly connectors that can be torn off accidentally.

If you're confident doing it, then I guess you do you.

Do not dismantle your GPU to redo thermal paste without checking your warranty. Some manufacturers void your warranty if the little tamper sticker is removed, or if they note a non standard thermal paste.

The OP got it sorted with a driver reinstall. All this reapply thermal paste stuff is pointless in more ways than one.

So something I overlooked as this is my first AMD card since Vega64 is fan curve. The factory fan curve seems a bit conservative with fan RPM to low in relation to temp. I've adjusted the curve so 50c is 50% RPM through to 90c is 100% and temps are now a far more comfortable 56c and hotspot 68c without out any rebooting.

This did create an additional problem in that Adrenaline would factory reboot any time I shut down/rebooted! First I made sure that MSI Afterburner was completely removed as this applies GPU settings during boot but this didn't fix it. Turns out it's a known issue with Copilot so disabled it using PS and ViVetool and we are all good plus it fixed a minor issue with my MSI WiFi adapter.

The cards 2nd hand from a popular auction site but I will try and register it with Sapphire and see if I do have any warranty.

Having water-cooled previous cards I'm not phased by dismantling GPU's and I do have the Kryosheet to hand so I may still fit it at some point.

My 3070 FE was under 3 years old when it first needed a repaste, personally wouldn't use paste finally ended up putting a sheet of ptm7950 on mine, tried a few cpu pastes i had laying around first they pumped out in a week or two, ptm7950 been solid.

I had to replace the vram pads on a mates 3090 after 3 months as the temperatures were horrible. That was a founders edition.

A simple fix for the resetting of overclocking is to disable windows fast boot.

yeah cause he was mining crypto on it banging the ***** out of it at 100c+ for days on end

Yup, everyone was making bank mining on their 3000 series cards. The 3080 and 3090 ran especially hot though and hugely benefited from custom thermal pads and a re paste.

I went ahead and removed the factory thermal paste today and replaced it with the Thermal Grizzly Kryosheet i ordered! The factory paste was dry and crusty but cleaned off easily enough.

The Kryosheet was a bit fiddly as it wanted to slide around on the clean GPU Die but once in place and the cooler refitted I'm pleased with the results.

At desktop Hotspot temps only 3-4c hotter and in gaming 9-10c hotter compare to 20-30c previously.

Half hour well spent.
