I guess all that V-Cache is good at expanding under heat, beside expanding FPS 😀

L4 cache on ML will be safer and just as good, worked wonders on 5775c.

Well cache is HOT! 🙂 And Asus needs to fix their shitty BIOS it seems to provide normal voltages for x3D parts.

As I recall it, wasn't there talk about the extra thick IHS causing heat conduction trouble with the 7000 series, all for the sake of cooler compatibility? I haven't seen people complaining about 5800X3D burning itself, although it's not like I'd have been searching for such news either.

Asides from one 5800X3D, that Igor Labs pushed 1.5v into, there were no issues with it. It would be strange that the 7800X3D would have problems. Although we see people blaming Asus motherboards for these burnt 7800X3D.

Some people with Asrock mobo had theirs burnt out as well.

At 1st look it seem that it was on Asus motherboard... Asus were the worse (despite very expensive) MB for AM4 due to bios. I hope for them it is not the same with AM5.

when I considered moving to am5 I was checking the AM5 motherboard reviews and Asus indeed was the most expensive and the worse, so nothing changed. They even refused to send a sample for testing and send some different one, so the reviewer bought the refused sample just to find out its borderline unusable. So that is that. Days of ASUS being the "go to" brand seems to be gone.

I just built a new system with and Asus X670E Prime Wifi Pro and 7800X3D on Saturday 😱 Ive been following this since Saturday(https://www.reddit.com/r/Amd/comments/12tlk7s/7800x3d_just_killed_itself_and_my_mobo/?sort=new), Steve from GamerNexus bought the mobo and cpu off him so upcoming video will be interesting. From the update the OP said they just used an EXPO profile but used BIOS 0922 instead of latest at the time 1101("Improve system performance and stabilize AMD Ryzen 7000 X3D series processors") as 1101 was unstable with EXPO profiles. Im going to grab the latest bios(asus removed all other Bios's for that board and only 1409 and beta 1410 available now) and just run my RAM at default speeds for now.

Many boards are sold with stock settings that push higher voltages in order to increase clocks and performance, so they can look better when reviewed. Could it that those same settings are too aggressive for the 7800x3D? And reading about the quality of recent ASUS boards makes me sad...

almost every time there are problems with AM5, ASUS is behind it.

most power efficient cpu on the market uses technology that runs at 90 degees in cp2077 with h150 xt. why bother paying a v-cache premium and a 360mm clc to cool it then ? 13600kf+am4 mounting kit for my d15s would cost 310eur altogether, don't even have to throw out good 4133 c16 sticks. waiting for ML though, will have l4 cache below the cpu die.

Suspicions are now falling on old bios:
"I have always thought of EXPO/XMP as "verified/approved" settings for memory, and not so much an overclock. Especially since the QVL reflects that. This is not the case, and in fact the rated settings also vary by CPU, so just because the QVL says 6000/30-38-38-96, does not mean that it should work across CPUs," wrote Speedrookie. "With this in mind, as I state above, I purposely went back to a BIOS version which POSTed with EXPO which was not an approved version for X3D series CPUs and chalked this up to BIOS instability rather than a potential intention by the BIOS engineers. So for people on a similar build, I'd say just make sure to update your BIOS and forgo EXPO for the time being until we know things are stable and working as intended. The cause here is still speculative, however may be a good safety measure to take."
And this is supported by Asus recent actions ASUS withdrew the old BIOS from many motherboards

My Asrock 570x Taiichi had some default voltages set high for my 5800x3d but low for the RAM, took me a while to work through them.

And new BIOS from MSI. MSI AM5 BIOS Adds CPU Voltage Restrictions For AMD Ryzen 7000X3D CPUs After First Case of CPU Burning Up
While AMD did open some tuning features for its Ryzen 7000X3D CPUs such as PBO (Precision Boost Overdrive) and Curve Optimizer, the more hardcore tuning options such as the manual voltage and frequency adjustments were locked out. It looks like some older AM5 motherboard BIOS didn't implement these restrictions well enough and the ASUS motherboard became the prime example of chips burning out and being damaged permanently. MSI has now placed voltage restrictions in both the BIOS and the MSI Center application. With the latest BIOS, the AM5 motherboards only support negative offset voltage settings on AMD Ryzen 7000X3D CPUs which means that the voltage can only be reduced versus the stock settings & can no longer be increased as that option is now hard-locked. This is to ensure that the CPU doesn't get damaged due to overvoltage.
This really seems like an issue with motherboards manufactures pushing voltages and power higher to get more performance. But they overdid it this time.

Yeah well... time to review those MBs again with the newer "safe" BIOS to see if there's any noticable performance lost. (just theoretically speaking, doesn't need to be done with every CPU.)

Whilst I was always going to get the 7800x3d, i'm glad it wasn't released when I got the 7950x.

Everyone is pushing more voltages and performance on non-overclockable cpus. I dont see this being only Asus motherboards issue as all boards manufactures do it. I expect new bios updates to prevent that.

lmao, despite them being the best on the market, its usually the users that are the problem, too many settings exposed to an ignorant end user can end badly.
