AMD Ryzen 7 7800X3D CPU Burns Up

Things need to be put into some sort of perspective.

Gamers Nexus, by their own admission had to force and actively try to trigger the failure and it took a lot of effort even though they new what to look for.

We have had possibly 10 failures from Reddit, OcUK alone sold/pre-sold 500 units in April ( approx figures from Gibbo ) - so if the entire Reddit community worldwide bought them from Overclockers - thats a failure rate of 2%.

I'm not saying this situation is acceptable, but you can estimate the likelyhood of it happening are pretty slim.

All hardware has a failure rate.

(I'm currently building a 7800X3D and Asus B650E-E pc at the moment, we'll see if this post has jinxed me :D )

I was thinking about this today. There has got to be around 1/2000 7800X3D’s in circulation in the UK and as far as i know there hasn’t been a reported failure in the UK.

If you went to the races and a horse was 1000-1 odds you probably wouldn’t bother betting on it as it’s unlikely to ever win. Thats my strange logic.

I've thought for some time that for this failure to happen a number of things had to collide.

Some sort of garbage in the BIOS
Not running stock
The opposite of a golden chip

The failure sucks and is a bit more impressive than usual but I've not seen anyone say it happened to them on this forum. You need to crowdsource from the entire world to get a dozen reports so it's not widespread.

Then since it can be boiled down to a bios update you get your update and it's sorted.

Decent drama but without hundreds and thousands of people with toasted chips there's no fuel to keep it going.
 
I will admit that I've only read some of the pages here but I've just finished building my Ryzen 5 7600X build with an MSI B650 Tomahawk WIFI board. First time I powered it on, I went straight to the bios (haven't flashed as you will see) and it says CPU core voltage is 1.31V. Am I right in thinking this is very worrying? I've seen that it's meant to be limited to 1.25V and while basically idle, it's at 1.31? My plan is to flash to the newest bios then restart again and see what I get then. I'm not sure whether to go for the beta bios (which I guess may be more likely to have bugs) or the latest full release which doesn't have the X3D fix.

Also, I see in the screenshot that my DDR speed is 4800 MHz when I bought 6000 MHz RAM but that problem seems secondary at the moment.

Sidenote, this is my first time with a clickable bios, it's very strange.

Im using the same board if i was you I would flash the latest bios. Also its the SOC voltage that is a cause for concern on AM5. What ram kit are you using?

Thanks for the reply, just setting up my USB drive with the latest beta bios now. I guess I'm quite rusty on hardware stuff as I didn't realise the SoC voltage and Core voltage were different although I'm doing a bit of googling now.

The RAM I'm using is Corsair VENGEANCE DDR5 32GB (2x16GB) 6000MHz C36

You need to F7 and be in the advanced menu to see all the voltages and what they are running at.

What is the serial number on that ram kit?

I’d imagine those kinds of numbers have been sold per day.

It seems bold to assume that the number of reported failures is equal to the true number of failures. I'd have expected a single digit percentage of failures to get reported in this way.

The other worry is whether these problems are going to increase in likelihood during the lifetime of the CPUs. It might be very rare with a new chip but as chips naturally degrade over time does it increase in likelihood? Are you going to be happy if your high-end CPU blows up after 18 months or a month after the warranty ends?

The soc is effectively what you would traditionally call the uncore so everything in the cpu that isn't a core complex :) - Memory controllers etc all sit in the uncore or SoC to use AMD terminology :)
 
I read somewhere earlier that ASUS is adding a warning in BIOS that enabling EXPO will void your warranty. I was surprised. Is there some persistent record of your settings?

How on earth can EXPO, a memory profile created by AMD, that HAS to be turned on in order to reach the memory speeds of the RAM you bought, cause the warranty to be void ?
It's crazy.

I would expect the argument to be that AMD supports stock memory but gives you the opportunity to use overclocked memory at the cost of warranty if you want.

Which should be fine but they should avoid promoting with overclocked memory as that means they're advertising performance that has no warranty by their rules.
