so... i got my 7950X around a week ago and had often BSODs and general instability across the board. (Games, Low loads, idle)

i thought my Curve Optimizer was a bit too aggressive. dropped it from -25 to -20, then to -15 and then to -10. still crashes.
verified memory stability over night (memtest ran to 1100% with no errors.) and now i thought about running core cycler.
latest bios, fresh windows installation, RAM at 4400 jedec speeds and everything 100% stock.
Core 0, 2, 4, 6 and 14 are unstable at stock speeds and needs a plus 10 to 15 CO to not imediately error out.
i borrowed a 7700X from a friend and it works perfectly fine in my system. it's the 7950X.

i think that i'll not buy another product from AMD after many years of constant problems.

does it error on Y-cruncher & prime95 too ?
If it's doing it at all stock even with PBO off, AMD would most likely send you a replacement cpu.
 
y cruncher crashes the whole system within 15 seconds.
and this is P95 AVX2 small fft (single core)
See if you can RMA it from where you bought it, if not try AMD directly.
 
What motherboard do you have? I got a 7950x and an Asus B650E-E, and I had to lower Vcore (-0,015V offset, helped with the instant reboots), and add positive CO (helped making P95 stable) on some cores to make mine P95, 1 Core 1 Thread, AVX2 smallest FFT stable (ish), work in progress, but it can run many iterations of corecycler with no errors now, where as before it would reboot or BSOD (@bios defaults). I suspect it just boosts too high for AVX2 single core/thread, and hopefully AMD will fix it :wtf: I also hate how different the CCD's behave:

X670 Aorus Elite.
completely unacceptable imo. a CPU must be 100% stable 24/7 in the hardest stress imaginable. and i can't even play games properly... Overwatch 2 and BF1 BSODs within a couple minutes.
 
I agree, not acceptable. This platform has a few wrinkles AMD needs to iron out.
 
Teething problems are to be expected when a new platform is released. I can remember quite well what problems I had with intel when I got my Pentium II. The motherboard came with an unstable beta bios and the system did also crash on a regular basis. To fix the problem I had to get a replacement for the motherboard.

Maybe your CPU is just a real lemon, as others said: RMA it. If you ordered the parts online you might still be within the two week window to return them all and get an intel replacement system. Instead of posting on a forum I would have simply returned everything.

i mean you don't have to read it or comment on it.

"teething problems" :roll:
when was the last time that AMD had a product launch that was not a complete mess...

If everything crashes so fast despite being in stock settings, don't bother with the system and processor, I think, send it directly to RMA.
 
I don't like Core Cycler. It tells me my 5900X is unstable even though it is not..
 
Did you encounter these errors after you OCd it? Maybe the CPU was fine until you killed it? Also, can't you just RMA it and get another one? A BIOS update might also help.

Like I've said before, OC on any modern CPU is completely pointless.
 
AM4 had L3 cache issues for months after release, AM5 is a new platform so I expect it to have issues which is why I'm sticking with AM4 for the moment. If it is an issue with the cpu report it to AMD and RMA it for a dif one to see if it also has issues. You may need to wait for a bios update for stability.

I don't run core cycler but I do use P95 to test for stability. If it takes a positive core offset to get you stable do it.
 
I've never had good experiences messing with curve optimizer, it's only ever caused me headaches. Enabling PBO, bumping the load line calibration, and making sure my heatsink is pasted well has been my MO since the 5600X. I've never understood people slamming an all core -30 and then scratching their heads when their CPU loses stability.
 
Just before you rma the cpu. I asume you have tryed reset bios to default settings.

If there are a newer bios version for your motherboard, have you updated it?

You said that a 7700x works flawless, so yes it could be your cpu. It's just that a defective cpu is so incredibly rare. Before rma I would also if possible, try the cpu in another system. Also I would take a look at the motherboard vrm temp. A 7950X stress the board more than a 7700x do. But to really be sure 7950X is defective. There is really only one way. Test it in another system. But be sure that board is up to the task with cooling and vrm. Your friends pc might have a cheaper board since I only has a 7700x. The cheapest boards tend to cheap out on cooling on vrm or make the VRM insufficient to handle load from a 7950X. 7950X can go for up to 230 watt at full load. Also a last step, tjeck bios for any enhancement activated. Motherboard manufacturers has the tendency to put example core enhancements on from stock, but it also means the cpu running out of its stock operating area. With can make the cpu unstable as well.

Else this is one of the hazard by going first to a new platform. You becoming a geniu pig for testing in the wild.

Adopting new hardware in the beginning, is the risk you will have to deal with. Am5 is not alone, Intel has had its issues as well. As of lately we can take nvidia firehazaard adapter for rtx 4090 or that many cards has coil whine and worse than normally, but amd is no saint here. It assumes that amd 7900 xtx reference card has temperature issues that makes the card thermal throttle. Adapting early, is not with out risk.

Are you running the latest BIOS for the board that was released 2 days ago?


Test your 7950X in your friends PC if that is possible and if it exhibits the same behavior then you will know for sure the CPU has an issue.
 
I am using a Ryzen system without ANY problems for 5 years now.

You obviously did not start this thread to get any help, just to troll.... von daher wär es vielleicht sinnvoll du würdest selbiges einfach tun.... Dich trollen.

Da du nicht an vernünftigen Umterhaltungen interessiert zu sein scheinst, werd' ich Deinem "Rat" folgen und Deine Beiträge zukünftig einfach ignorieren. Mir wird dadurch mit Sicherheit nichts weltbewegendes entgehen.

This is my same experience, haven't had any issues whatsoever. No USB dropout problems, driver problems, or power problems. The only issue I've ever had with my AM4 system was a bad BIOS release by Gigabyte that broke PBO support on my old 5600X for a few months, which was fixed by another BIOS update.

Now I have a 5800X3D and 6950XT and haven't had a single issue that wasn't caused by me messing around with settings too much :laugh: I think a lot of these problems come from people using subpar power supplies. I've never had an issue with Seasonic/Super Flower gear though
 
Hi,
Pity maybe a x3d will work :cool:
 
@GerKNG can you run ycruncher using stress test option and set affinity to only individual cores while testing? If it's boosting properly and still stable through BKT/BBP/SFT tests, you're probably okay.

You are running a custom corecycler config so I just don't have much of a reference of where it stands.

any kind of load on the mentioned cores is unstable.
i can set world of warcraft to core 0 only and it locks up within a minute.

y cruncher, P95 without AVX, cinebench single core. doesn't matter

Sounds like an immediate RMA if you need positive CO just to stabilize......still, I'm surprised this bad CPU streak has followed you even to a new platform. Unfortunate

It shouldn't be this complicated, I think you made the right move refunding and going to Raptor Lake.

well i am not alone with this problem.
yesterday in a stream from buildzoid there were people in the chat with the exact same problem (one had already three 7700Xs)
 
So, a faulty CPU.
