Lmao, chat bots don't reorganize/rewrite statements and then forget to eliminate the duplicate, but it's one of the most common mistakes I do when I'm editing my own articles.
Calling it a "chat bot error" is basically admitting you've never written anything longer than a Twitter post, and yet are trying to judge an actual writer, who's only fault is working for a company that can't afford an editor.Reply
"One interesting point about AMD's statement is that it eludes to whether or not the issue is just on its Ryzen 7000X3D processors or whether it affects all of its Ryzen 7000 processors entirely."
That's unfortunate. CPU competition is good, but both Intel and AMD have been flying a bit close to the proverbial Sun lately and those wax wings are only going to tolerate so much before they melt.Reply
"Gamers and their requirements are why everyone is flying close to the sun."
ah, such a market. it was Lotus 1-2-3 and WordPerfect and DBase III that made the killer app crew. all productivity enhancers. these days it's time waster the PC world is relying on. that's progress, I guess.Reply
well... the PC-gamer market isn't the same thing as crypto-mining (a truly wagering experience) or FanDuel and the like. I suspect that the Big Boys run on IBM Big Iron running linux, not a bunch of PCs running Netware.Reply
Each of those three could have turned me off PCs, if I hadn't been completely smitten by then and running Microport System V release 2 on my 80286, porting code.
It was Visicalc, WordStar and Vulcan aka dBase II for me from the very start on CP/M on my Apple ][ clone with a Z-80 softcard, all those 2nd and 3rd runner-ups just made things worse.
I yielded to M$ office after GEM lost, but tried every alternative from Nico Börries, since he sold the Turbo-Text-Toolbox as a WordStar replacement (that's LibreOffice today, in case you don't know your Personal Computer history).Reply
I still wonder why this issue surfaced after all these months 6 months+ of Ryzen 7000 series AND X3D refresh being a month + already present in the market. There should be more for this. But I still cannot think how can AMD and Mobo partners can skip the SoC voltage specification. This is exactly why I always mention AMD needs to provide datasheets. Intel does it and they have voltage specifications for a lot of variables. Esp given the fact how this is EXPO related or at-least it makes that like it.
So many reviewers and OCers and everyone ran these processors with EXPO. AMD should really need to put focus more perhaps.Reply
It sounds like this is more a case that the X3D is uniquely vulnerable to over-voltage and pver-current conditions but the conditions were still there on the non-vcache chips. Reply
7800X3D here with Asus X670E-A motherboard and Corsair VENGEANCE 32GB (2x16GB) DDR5 DRAM 6000MT/s C36 AMD EXPO Memory Kit SKU CMK32GX5M2D6000Z36. I updated to BIOS 1202 recently but now see "Beta" BIOS 1301 which i'm personally not installing for now. I did turn my memory EXPO II BIOS setting back to Auto until they work out this apparent over CPU Voltage issue with EXPO memory set. I did notice that with EXPO II setting on the memory (I was using the memory BIOS EXPO II (3000 MHz) setting until yesterday when I turned it back to Auto (2400 MHz)) my 7800X3D CPU VDDR_SOC Voltage went from EXPO II Max seen of 1.340 V to Auto Max seen of 1.020 V.Reply
I'm now updated to 1303 BIOS and re-enabled EXPO II settings (DDR5-6000 (3000 MHz) memory). CPU VDDR_SOC MAX is 1.240 V like you had with 1301 BIOS. That seems reasonable. I'll run at this and see how things go.Reply
In addition, I noticed these 7800X3D Package Temps (after gaming a little): EXPO II memory BIOS setting: 72.0 C Max Auto memory BIOS setting: 66.4 C Note: all my data is found using CPUID HWMonitor in Admin modeReply
What we have here is Mobo suppliers pushing the limits to get to the top of the charts knowing full well the blame would be focussed totally on AMD, its not surprising that the majority of failures seem to be related to (but not confined) ASUS who are seen as a halo brand with ROG and need to maintain that position and justify the premium they charge. AMDs failure was in trusting the Mobo makers to be sensible rather than implementing a hard cap which they have now done, perhaps the refresh later this year can take the voltage without error we will find out later i guess but for now just update the BiosReply
AMD didn’t learn from previous iterations of motherboard maker shenanigans, like ASRock 970 boards — ostensibly rated for the 9000-series FX chips that caught fire and ASUS’ penchant (via the Crosshair Formula Z) for underreporting the vcore.
Of course, AMD should have been tarred and feathered for the 9000 series in the first place.Reply
For me this is AMD's FDIV-bug moment: they either come out now and promise "life-time" replacement warranties, or there will be far too many current owners wondering if they should now burn up their potentially damaged CPU to get a known-good replacement.
And let's get rid of that silly notion that PBO/EXPO activation kills warranties while they are at it. It's an advertised feature and using that may not affect warranties: you make it safe to use or you leave it out.Reply
I have to say nothing really excites me about this motherboard chipset. They obviously use way to much current/wattage which is what is causing this problem. Maybe instead of simply making things faster they should focus on making them energy efficient. I could say the same for graphic cards. When we approach using over 500 watts of constant power just to feed the beast I say we have gone too far. I wouldn't want the monthly electric bill. Reply
A few days ago, my 7950X unexpectedly failed. I had kept all settings on Auto, except for enabling XMP DDR5-6000. Initially, I experienced random reboots, but they became more frequent over the past week. Eventually, the system failed to boot into Windows, resulting in a blue screen.
I suspected that the issue might be related to my Windows installation or M.2 drive, so I attempted to boot from a USB Windows Installer. However, it would get stuck right after the POST. I tried various USB bootable media, but only MEMTEST86 would launch. Running a test revealed thousands of errors before crashing.
To troubleshoot, I replaced the 7950X with a 7600X from my secondary system and everything worked flawlessly. When I put the 7950X back into the secondary system, it exhibited the same issues, unable to boot into Windows or USB media. Upon inspection, I noticed some darker gold markers beneath the 7950X where the memory controller is located.
In my 30 years of building PCs, this is the first time a CPU has failed on me. As the push for smaller nanometers continues, AMD should exercise greater caution with voltages as the CPUs seem to be a lot more fragile.Reply

This statement actually doesn’t say VSOC is the root cause. It’s just one of the power rails getting capped. All indications are VCore related. ReplyGothmoth - Thursday, April 27, 2023 - link
