The power of a 5800x with PBO and Curve Optimizer!!

It's a great CPU for sure. Thank you

It's a mix of good silicon and proper settings.

I have my 5900X at 5.1GHz using PBO with 3600MHZ CL16 memory. Not touched curve optimiser yet as I haven't really had the time needed. PBO doesn't even add that much voltage for me either so I too may have good silicon. That and I have a full custom water loop too which helps a lot and the room is air conned too 😉

It's your core 0 with Windows as I ran into that same issue at first. Set your fastest two cores (gotten from RyzenMaster) to -5. If core zero is one of those great, if not, set core 0 to -5. Set AUTO OC to no higher then 150Mhz. All three 5800x I have tested just do not like 200Mhz (can do it but with stability issues in testing) but are happy with 150Mhz and I get better scores across the board with 150Mhz too. Set the rest of the cores to -15. Test and see if it is happy. If not...just change core 0 to 0 and test again.

How hard are you pushing your RAM BTW? If you have it on the bleeding edge, that could upset a processor overclock too easily. How are you removing heat? Ai

I have -5 on core 0,2 (my fastest) and -15 on the rest @ 150Mhz PBO/OC....and it hasn't crashed since setting. I use default XMP as it already does FC 1800 1:1 C16 which is good enough for me.

My two fastest cores are set to -5. Others in the range of -7 to -12.

My RAM is 3200MHz OC'ed manually to 3600MHz, 1.35V -> 1.36V, since at 1.35V it cannot pass memtest86. Timings are pretty mundane, something like 16-18-16-19.

My TTP is set to 125W because of an anemic air cooler (Gammaxx GT). Even at 125W the CPU heats up to 89C while running stress tests.

Idle temps are fine, around 36C, so I've applied the thermal paste properly 🙂

I would go for the updated architecture unless you already own the 3700x. Otherwise I would only upgrade from a 3700x if you must have higher fps at lower resolutions. Honestly though, if you just gaming a 5600x is the more cost effective option. The fps difference is minimal compared to the 5800x. 5800x if you also stream or do productivity takes though.

Memory is a little tricky right now as the bios matures. There have been some issues with WHEA errors for some people. Plus some boards are more finicky than others.

I have a 5800x (couldn't get a 5600x when I was looking) with a 16 GB kit of g.skill Trident Z 3600 memory OC'd to 3800 in an MSI x470 gaming plus at 16-16-16-32 with geardown mode on since this kit simply does not like to run at CR1. I was able to push the memory more without crashes when gaming but I couldn't stop the WHEA errors. I am fine with it though and happy I was able to go from a 2700x without buying a new motherboard.

This is why I am considering the most up to date now. I'm on an 1800x and that needs to change this fall lol Was going to go with a 3700x but why spend upwards of 300 when the 5800x isn't much more? Because I might try streaming in the future, but it's not for sure. I just don't see the point of getting a 6c now either. I'll consider that when I rebuild a small form factor with the 1800x; make it so I can drop something better in as some time goes by... maybe? But that would be for shits and grins. As hesitant as I am on the 5000 series (just wanted to give it enough release time, work the bugs out, etc.), the more I may go that route. Just skip over the 3000 series. They are all decent while perhaps the most important detail to consider being the 7nm nomenclature.

But if OP is able to run 4 x 8gb sticks of RAM @ 3800 mhz on a Ryzen board... maybe what I have been waiting for has finally come through? Memory issues are really the only kink with Ryzen for me. Otherwise, I just refuse to build at home with Intel. I'm not paying that kind of price. If I want to pay that much, I'll consider a 5950x (I'm not, don't worry lol). At least, not for the little bit I actually do.

So I'm still curious what exact RAM kit OP is running. Is it 2 of the same kit or a 4 stick kit? I assume they are all single rank but, dual rank? I don't 'know' G Skillz memory like I might better understand samsung sticks, for instance. I ask because it's kinda like, "what's the point in investing in a 5800x if I can't get the right RAM?" That's how Ryzen is. Awesome CPUs, if you can get the right RAM to work out. I shouldn't sweat the small bullets now, I just didn't realize they don't 'seem' to be having as many RAM difficulties. This is promising to me, but also something I have been trying to get clear on for a while now. Supposedly Ryzen 5000 has better memory options, if I read that correctly like 5 months back.
