AMD RX 6800 RT cores defective or PSU problem?

[lawood]

Exactly, it's a budget unit and shoudnt be used with dedicated gpu's, for office PC's with igpu's its fine.

You still fail to understand that you just got lucky, you should be thankfull.

If you prefer to bury your head on the sand and call drama what you dont like to read, be my guest.

Seriously shut up man, no I didn't get lucky, buying a paperweight labelled as a PSU for $15 that is a fire hazard and is likely to blow up would be getting lucky, that would be dumb luck however, I might be cheap but I'm not dumb, buying a PSU that isn't a top tier unit but from a reputable company who probably sell them in the millions and are fine for 90% of pc builds is hardly getting lucky, it is what they are designed for.

I've been building PCs for longer than some of you were out of nappies, yes it is dramatic and alarmist, thanks for the help before the bed wetting

 

[lawood]

It's not about not being top tier, is about being the absolute lower tier. There are much better options on the market similarly priced.

buying a paperweight labelled

Honestly, it really isn't far.

I really dont get why you are getting emotional about a PSU, all you have to do is accept the model is sub par to put it midly, it's a fact. Logically such models are not suited for dedicated GPU's.

If you've been building PC's for such a long time you should know better.

I'm not emotional, it is fine for a lot of dedicated GPU's repeating yourself in a different manner doesn't make the stuff you're spouting any more true, you are a bot who repeats the same information as a lot of so-called experts on this and other tech forums and insist only top tier gold rated PSU's should ever be used, ideally yes, though life isn't ideal, if what you are saying is true then they wouldn't sell in their millions, I have ran a 6700xt, 5600xt, 580's 2070 S, 2080 S all on this PSU without a hitch, must've got lucky so damn times huh? I know your opinion anyway, you don't have to re-word it again to get out the same wrong information though, cheers

I have ordered the Corsair RM750x Shift, will be here tomorrow

I have the 850x Non-Shift and it's excellent.

Anyway one way to further troubleshooting before buying new stuff would have been to downclock the card and see what happens.

 

[lawood]

Yeah, it's fine, until it isn't.
And with PSU's of that quality the most likely scenario when a fails occurs is to take other components along.

I know your opinion anyway, you don't have to re-word it again to get out the same wrong information though, cheers

It really isn't an opinion.

I'm having a very difficult time thinking a 600w PSU couldn't cover 220w at peak.

Yes further troubleshooting. This taken on a PSU built in 09'.

 

[Marcus L]

Received and installed the RM750x Shift, as I knew/thought it was not the PSU, still crashing when enabling RT so it is 100% the GPU, was bought in Nov so I am out of luck trying to get a return on eBay

 

[damric]

I've got an EVGA 600W in my home lab right now. It's very mediocre. Vega 56 wouldn't even post with that thing lol. It does ok with low power GPUs and that's about it. Go figure it only has 1x PCIE connector so yeah it wasn't designed for much.

It runs very hot, yet has a very low temperature rating threshold. Ripple is bad too so forget stable overclocking.

There's two points to consider (regardless of OPs troubles).
-Software measurements aren't accurate/fast enough to measure power spikes
-RDNA2 reports GPU chip power only, not total board power.

Noted.

Issue only with RT enabled is all the information we've gotten so far. The game crashes. Without RT, runs fine.

That means to me, No RT system warmed up, a little less power draw. Spikes would still be there. Perhaps that extra 50w with RT on (if this number would be accurate guessing without testing) could make a game crash, rest of system runs fine, turn off RT, continues to run fine. (?)

Literally the only symptom you have is RT off game crashes and no diagnostics at all.

Then let's go buy a psu.
All seems logical to me!!!

What do you want by way of diagnostics? it was logical as when I bought the GPU I had planned on buying a new PSU anyway, the issue just forced my hand, the old PSU was not suitable for the 6800 and I knew this however the PSU ran it just fine when RT was turned off as does the nice new PSU I have bought, though the issue still persists

I did list some things you could try a couple pages back. 10 things actually. All of them viable possible solutions.

But if this where mine, I'd partition my drive or a different drive with a nice fresh windows installation.

I'll go have a look, I may have tried them already as I have tried a few different things to no avail, yea partitioned Windows install might be the way to go as I don't fancy changing my main Windows installation again as have only done it recently...

1. Try the card in a different rig - only have 1 other PC in the house, it is also using the 600w EVGA PSU I was using until today, must've gotten lucky twice with these fire hazards
2. Set your current system to defaults - Also done, reset bios to default and updated bios
3. Enable/disabled resize the bar - had thought about this also, will try that shortly
4. Limit the RT settings in the games -
5. DDU completely, then try the drivers. Remove amd/nv/Intel - also done and tried 22.5 something older drivers, december and latest january ones
6. Fresh OS on a different drive - may try this tonight
7. Monitor with HWInfo64, create logs - I will do this tonight
8. Monitor with GPU-Z. Logs. also do this tonight
9. Different display port/cable/monitor no other monitor to test though will try hdmi cable, currently using DP
10. Freddy's coming for you.....

That's why I suggested it that way cause totally get it. File transfer takes time and patience.

What I experience feom swapping a lot of cards with overclocking, freezes, hangs, driver crashes and benchmark crashes is that the operating system does in fact take a toll while reducing performance in some benchmarks. And in some cases total system instability.

Not a last resort, but a viable way to just test the card with fresh software. Of course keeping the main OS you use is important. I'm sure you've got backups.

Yep just saw that.

Well you've tried a few and have a few more to try.

Good Luck!!

 

[Vya Domus]

Hate to be that guy but told you so, wish people would get good advice on this site but more often than not they don't.

Driver crashes/bsod almost always point to an issue with the card. As I said in my first comment, do not buy second hand GPUs that you can't verify in person. Only thing worth trying at this point to rule everything out entirely is a clean OS reinstall.

 

[wNotyarD]

@Marcus L just for the sake of experimentation, is there any enhancement/override enabled on Adrenalin settings for every game your driver is crashing with RT on?

I have a 7900XTX myself which gives me LOTS of crashes on a SINGLE game (Phasmophobia, no RT involved), and I fixed it by disabling any and all Adrenalin override for that game exclusively.

Well considering I bought the GPU in November, it would be a bit hard to take your advice of not buying used components, and I've bought tons of used stuff over the years it's rare I get burned, also if no one bought or sold used parts then it would create a ton of e-waste, there's nothing wrong with buying used, unfortunately on this occasion it seems I have lost out but that's down to me as I should have thoroughly tested the GPU when I bought it and had the time to return it, I have messaged the seller though I'm not holding out on getting anywhere on that front, i will likely sell it on the cheap as faulty noting the GPU seems to be fine unless using RT.

Smells like a GPU perfect for BOINC or F@H at this point. Probably put in "sold as defective" to ebay and *maybe* you might get somewhere.

Got it listed on eBay as for parts/not working and have put in the description that it runs any game fine except for when RT is turned on, obviously the price is lower to reflect this but have also protected myself doing this, I may keep it and just accept it won't run RT, it's not like I am missing much anyway as AMD's RT perf isn't really all that great anyway

Guess you got a fair deal. You're not missing much with raytracing anyway.

He put it up on ebay now with that description. At least that's how I understood, not that he originally bought it from such an ebay listing.
