Question RX 7900 XT Crashes - Help!

[Cableman]

I recently replaced my GTX 1070 with a RX 7900 XT. Finally had time to install it today. Used DDU to clear the old drivers. Ran Heaven a few times without any problems. Then started a few games to check the performance. Tried Control. Within 5 mins, I get a black screen and the PC crashes. It started doing the same in Witcher 3. Then I tried Heaven again and was running GPU-Z to monitor the temperature. It never goes beyond 76-77 degrees. After a few minutes, I get the same black screen and crash (at 75 degrees). No other apps are running.

Any ideas? I would appreciate any help.

Can the 2 PSU trick with each 8 pin going separately to each PSU work as an easy way to see if it's a power issue?

 

[scineram]

I'm using 2 separate 8 pin cables. Also, the PC can be turned back on right away after the black screen and the first second or so after the black screen, I still hear some audio.

What audio? That was playing before? Is the audio connected to the motherboard analog outputs?

 

[Cableman]

If the PSU is having issues (and sorry if this was already tried), I would do two things.

1: Set the power limit to minimum (I think I saw -10%)
2: Enable undervolting. There is an "auto undervolt" setting. Or, you can manually drop the voltage down.
3: Disconnect anything else that is powered up that is not needed in the system.
4: Try a different power plug in your house. You may have an issue where that plug doesn't have enough current, or it has dirty power, which will become a bigger issue as current draw increases.

Find a friend with a machine to test the GPU in.

I tried 1 and 2, no luck. I might try 3 and disconnect the HDD or something else. I might as well try 4 too.

Unfortunately, all my friends are using laptops (boo!).

Actually, your comment gives me another idea. I have an old 450w PSU. Is it possible to just connect that PSU to the outlet and then from there just with 2 8 pin cables to the card - not powering anything else and the PC running off the main PSU?

Yes, audio that was playing before the crash. I have a USB DAC that I'm getting audio from.

I would use the other way first, 450W for computer and 750W for card.

Anyone sees a problem trying this?

You'll need to jump pins on the 24 pin to get the extra PSU to power up. Or use one of these: https://smile.amazon.com/24-Pin-PSU...=1675798313&sprefix=psu+tester,aps,180&sr=8-7

I would advise against this. Having two supplies connect to the same ground plain on the GPU can have unwanted side effects.

You could hook the 450W up for the CPU and motherboard, and then your 750W just for the GPU. But don't split the supplies across one device.

I need to look away from this thread before @Cableman cooks his whole setup. Please, just test a new PSU and if that doesn't turn the trick work on the GPU RMA. ha.

Where is the fun in that (...puts down the jumper cable from the car...)

Have you tried just lowing settings down to bare minimum in a game that crashes?

Set the resolution to like 720P, set all settings to nothing, and then set the frame cap to something low. Like 30fps, or at worst 60fps.

This should drop the load on the GPU way down to ware it just sips power. a 7900 XT with vsync on and low settings only uses about 110W of power.

I tried capping the frames as suggested in a post above. Tried 30 and 60, no crashes in Heaven, which crashes every time without the limit. Capping the max frequency to 2600 also stabilized it. I'll check a few games tonight. I'll probably have to pick up a 1000w PSU and just see if that does it. I think I've reached the limit of trying to figure it out without either a new PSU or GPU...

Update...Heaven works without issues, but the PC keeps crashing in Control. I am going to order a new PSU today. Can someone comment on these options (all 1000w):

- Corsair HX1000i Platinum
- MSI A1000G Gold ATX 3.0
- EVGA Supernova 1000 P3/P6 Platinum
- EVGA Supernova 1000 G+/G5/G6 Gold
- Seasonic Prime 1000 Titanium (maybe I can keep the current cables since it's the same brand and just swap PSUs?)

I would choose the Prime Titanium, but I'm a bit of a Seasonic fanboy (I have the 750w Prime Titanium). All of those PSUs are good choices, though.

I have the same 750w Prime Titanium as you, which might be what's causing the problems in the first place.

Surprised the PSU is the main suspect. Esp since power spikes have improved with latest gen cards. Why have we not heard of tons of ppl complaining about 6800xt issues on 750w PSUs?

If it is the PSU, it may be an unusual anomaly with it rather than its rated power.

There are threads - perhaps not here so much but on Reddit and other platforms - where power supplies got crushed by 6800XT and higher cards but should have been able to handle them. I believe, but am not sure that typically it was multi rail PSUs that had the most issues. I'll be honest and say that I don't even really understand how that works, but some part of the PSU wasn't able to handle the quick changes demanded by the newer hardware.

As I mentioned before, my BitFenix 650W gold PSU was/is A tier rated on that LTT list *but* has an asterisk/got demoted as it has issues with current gen, spikey cards. Specifically 6800XT and higher. @igor_kavinski discussed his 750W Seasonic mistrust as well.

I used to be Seasonic all the way, now all the real PCs save my gaming PC (RM750 is on the shelf, ready to go) are running Corsair Gold PSUs. They've yet to sour me, I've had bad luck with fan noise and coil whine on their lesser models though.

Personally, I used this PSU on a 3090ti build and was quite impressed with it:

I mean, the platinum is only $30 more and when we are dropping this kind of money that seems like a step I might take.

I am pretty sure the RM850x would be plenty and with a $70 savings I might just stick with that. Plus, I could that 850W one in an hour and get instant gratification.

What is the difference between that Corsair RM1000x and the HX1000i? Is it just Gold vs Platinum? That's my top choice right now. I am seeing some conflicting feedback on the Asus units...

 

[Stuka87]

IMO opinion, Corsair RM supplies are among the best you can get currently. Not just because of the supply itself, but because of the type 4 and Type 5 cables they come with. These cables have filtering caps on them to clean the power up. Transients can cause a lot of noise at higher current draws, and this can actually be a reason the system crashes during these spikes. By filtering the power right before it goes into the device (motherboard, GPU, etc), there is a lesser chance of experiencing issues during transients.

If the OP can find an RM supply, I suggest going for that. It doesn't even NEED to be a 1000W, a 750 or 850 should suffice. I actually plan on seeing how my RM650X does with a 7900 XT when I get around to buying one.

The HX uses "Type 3" cables, which do not have filtering. The RM series uses "Type 4" cables which have filtering. You can buy Type 4 cables for the HX supplies. Corsair sells a kit.

So something like the RM1000x would be good? Should I worry about Gold vs Platinum? And what do you think about the EVGA Supernova 1000 P6 (quite compact and Platinum, not sure about the type of cables)?

 

[In2Photos]

I've been a Corsair PSU guy. I've had several of them over the years and they have treated me well. Last year I got a DOA RM650 for my son's build. The replacement has worked fine. For my daughter's build I got a Deep Cool 750W Gold for $50 and so far so good, probably one of the best deals I've ever had on PC parts. For my build I chose to go with FSP because I heard really good things about them coming from the server market. I really like the PSU except the fan. This is the first PSU that I have had where I can hear the fan. I've debated on changing it out to something else. Maybe I should have stuck with Corsair.

And I think you mean EVGA 1000 P6? That supple is manufactured by Seasonic. Asus doesn't make a 1000W P6.

To my knowledge, Corsair is the only company to offer inline caps with their supplies. And its specific to the RMx as I recall.

And I should note, some people DO NOT LIKE inline caps. because there is a section of the cable that can't be bent. On my PCIe GPU power cables for instance, I can make an immediate 90 degree bend out of the GPU, but then there is a 1.5" section that won't bend. The same goes for the24 pin. There is a 1/2" right out of the connector that can bend, then a second that can't. But I can still route the cables as I want, so not a big deal to me.

Yes, you are right, EVGA 1000 P6. I edited my post (brain is fried with all the PSU info I crammed today). They have a G6 and a P6, which are basically the same. They also have some transient protection, but I think not in the cables. It's also quite small at 140mm vs 180mm for Corsair. Any info on the EVGA PSUs?

They are made by Sea Sonic, which typically makes great supplies. Not sure I have ever had a bad Sea Sonic. Though you have a Sea Sonic now, and while we have not yet proved it is the cause of your issue, it does appear that way as it only happens at higher loads. But that could just mean your particular supply has an issue, and not that its something that impacts all supplies made by them.
