Question Is there a comprehensive guide for the 7800x3d? Things to check for, things to make sure you do.

I'm about to build a 7800x3d system in a few days. I know to update my BIOS (I have a Gigabyte board) and monitor the SOC voltage in HWInfo to make sure it doesn't go over 1.3V.

Is there anything else I need to do or watch out for? Does someone have a guide or a checklist?

For instance, should I be setting EXPO on my RAM? How high can the RAM speed be set? (I will be using 6000 Mhz Trident Z5). Should I start it off at a safe limit first?

Just curious because I want to do everything right the first time.
 
I don't think there is a guide. Expert says that internal measure of vcore are unreliable. I won't get that cpu given all the issues. if you still plan, I would ensure that the bios is on the latest revision. The xpo memory is not likely to cause issues given its 6000 mhz.

Just make sure you update to the latest BIOS and you're golden.

My system has been fine with EXPO enabled for the last month.

There is only a small number of systems that blew up fast in the first place, so having a CPU running for a month doesn't mean much.
Nobody can say if this isn't a long term problem, your temp protection could still be degrading just at a very slow pace.
Nobody can say if in a couple of years there will be a whole slew of CPUs breaking down or if the Volt limit actually stops it completely.

That’s a whole lot of nobody can says… 😂😂

Good thing I don’t live in fear of what might happen in the future or what could happen or if it could happen.

People that do should probably just build an Intel system… just don’t forget the AIO.

Yeah, that's why people start making these threads, because there are a lot of things to consider and not everybody has the money to just buy a new mobo and CPU as replacements until the RMA goes through.

$20 cooler is all it takes.

It's been fixed. BIOS updates have been released from all vendors. Nothing else to see here. I'm sure it will be talked about for years though. If people are paranoid about what might happen my suggestion is to build Intel. It still begs the question though... do these same people drive cars? Because people die in car crashes every day.

$20 cooler is all it takes.

Now that's what I wanna see... a build by the guy putting a $20 cooler on a $500 CPU that is hotter than an oven. :ROFLMAO:

Probably the only guide you need to know: keep up-to-date on BIOS for your motherboard. AMD's root-caused the problem and providing an AGESA that locks down a limit on voltage rails so that you don't have to worry about whether or not your motherboard mfr. did. But you'll need to update to get it, once it is you can safely set EXPO with no worries.

Didn't you notice the link?! That's exactly what they did.
All the coolers hit the same 100 Degree limit, AIO included.
The only difference is that the $20 cooler will only blow 245W into your room while the AIO will blow 315W into your room.

Yeah I did... I was mainly talking about how many people out there actually do it though. Every 13900k build I've seen has been with an AIO.

At the end of the day as long as you are happy that's all that matters. I love my Noctua even if there were less expensive options available. Sometimes paying more based on reputation and customer service is fine.

Yes everybody uses an AIO and leaves the auto overclock in place, same for ryzen by the way, and then they wonder why all the intel CPUs reach 100 and all ryzens reach 95.

Mine runs a bit cooler than that... presumably due to the lower power draw than the non x3D variants plus the fact my ambient temps are pretty mild.. 68C.

I have noticed that my Ryzen idles higher.. in the low 50C range. Gaming is in the 50-60C range and even tasks like Handbrake encoding only had it in the low 70's.

I've done a couple 30 min all core burn tests using Furmark and in both cases it hit 89C after 1 minute and never went any higher. I suppose I can thank the Noctua for that.

As for OCing... haven't done that. It's my understanding those days are behind us. I am planning on OCing the GPU a bit though but haven't gotten around to it.

Underclock the GPU, you can shave off like 100W and still get 95% the performance. They really do push it to the limits.

Have my 3080Ti in "Summer" mode now only pull 280W instead of the 350W it does stock.

That's cool... never really thought about it. I honestly don't even know what the GPU is pulling at max load... i know it's a lot though. :ROFLMAO: That's why I went with a 1300W PSU... PCPP was showing like 900W for the build and I wanted the headroom.

Summer here in the PNW is a lot milder than summer in FL or TX... but I'm definitely interested.

I do have a water cooled build, so that 'dumps' heat into your room is real. And my office isn't the largest room so it heats up quick. Nice in the winter, but summers are generally pretty humid and up in the mid 90s pretty regularly.
