Is my 5950x a dud?

From what iv read pumping that many volts into 7nm degraded the 3000 series in few weeks. Most people saying not to go over 1.25v all core clock. Apparently the standard boost algorithm is smart and doesnt cause degradation even when it spikes voltage

Some 3000 series owners had degrading chips even 100% stock.

So I'm of the opinion there isnt enough evidence to actually say what is safe and what is not.

Luckily for me, if my CPU ever degraded to the point where it ran slower than stock I'd be able to swap it for a new one - I'd be surprised if you guys couldn't either given how its nearly impossible to prove someone overclocked a CPU
 
This is maybe a bit of humble bragging! I'm not usually lucky when it comes to silicon lottery but (touch wood) I seem to have done well this time.

To OP, I would give it a bit more time and observation. Maybe check cooling - I originally had higher temps like you towards high 80's / low 90's. Gave my PC a good clean out and temps dropped significantly and then saw much better boosting.

Yep see, this is absolutely night & day compared to mine. For the price I was expecting all 5950X’s to be binned like this... definitely think mine is at the bottom end of the scale whereas yours is near the top.

Will monitor the max hit core speeds for a bit longer but there’s just no way my silicon is allowing individual core speeds at that level. The whole pc build is only a few weeks old too and everything is clean :)

The 5950x is advertised as single core 4.9ghz and you want all 5.1? If you want a heavy binned chip you should be buying your CPUs from siliconlottery.com not OC UK
 
OK, so you're chip isn't the greatest for overclocking. Realistically outside of benchmarking you'll never notice a difference. Just like any other chip whether that be amd or Intel, if you want a good clocker, you've got to buy in bulk, bin them all and most likely take a hit when selling the rejects. I used to go through 20+ chips on average easily for Intel back when I was benching.

If you ignore manual oc and starting playing with pbo / curve, you'll get that single core boost raised no problem and end up with a more efficient multicore.

Hi Mike, - I recon this is with PBO turned on right?

Thanks

To get the same picture* you need to run a single threaded benchmark, preferably not too cpu heavy and manually pin its affinity to each core one at a time.
Else windows scheduler will always make single threaded task run on preferred cores. Other cores look like they never boost high because windows never gives them a single threaded job light enough.

* minus AutoOC, so boosting up to 5050
your cpu is fine

completely stock? looks to be like you have +200MHz AutoOC enabled

I installed new BIOS before installing the CPU. All I did was go to BIOS, set XMP, IF to match and RAM voltage manually. Only had it a full day - assume PBO / AutoOC needs to be enabled?

Yep, tried this with Cinebench R20, set affinity to various different cores while the single core benchmark was running. Like I said, most of them simply will not boost to 4.9Ghz no matter what I do*. The picture in my first post is the result of that, hence my concern.

* Unless I manually set them to 4.9Ghz in Ryzen Master @ 1.5v then try to run a single core benchmark, at which point it black screen crashes immediately.

yeah i guess my main concern is more with the single core boost rather than a multicore push as that will affect performance the most on a day to day basis. Not entirely sure how the boost algorithm works during a single core or single thread load (e.g. gaming), but I assume the workload gets passed from one core to the next “hot potato style” in order to keep the temps from going too high. If this is the case, my chip performance would suffer when the algo runs out of higher boosting cores to juggle with.

Or am I talking complete **** ? :D

To get a core running to 52xx you need to have PBO +200 on otherwise the max a core will do is 5050.


Gerardfraser posted this little program which will boost all your cores individually to their max current potential. You can use HWInfo or Ryzen Master to see what the cores are pushing.

Booster

From this you can set a higher negative value on the PBO CO curve on the weaker cores to hit 5 ghz+ all core individually

Unusual.
Seems like CCD2 will need heroic negative amounts of Curve Optimizer to boost higher.
1.5V on all cores would be an instant crash
You are lucky to have a working CPU after this. 1.5V is mental. The 1.5V value you see in monitoring doesn't mean the cores actually gets it (no more than 1.4V actual for me) and never at full core load.

So, has PBO automatically been turned on? I haven't looked in BIOS yet, other than to set XMP on RAM, but will check - I had a quick look at Ryzen Master which shows control mode as default???

OC mode: Auto Overclocking, field Boost Override CPU shows how much AutoOC is dialed in.
PPT, TDC, EDC for me are default 142 95 140. If different, means motherboard set its own limits

On Ryzen Master with Default enabled you should see a Max Clock of 5000 - 5050 next to the CCD, With PBO +200 it will read 5250.
