The boost I got and have 30% more give or take and the added cache smoothness be great.
Not in a hurry tho.
rdna3 card takes priority over x3d..and
a new monitor maybe
I decided agasint the upgrade to 5800x3D as zen4 made more sense

Yeah I am looking forward to seeing new cards, I don't have one yet so prices will decide if I wait for release, get a last gen card, or get whatever Nvidia 4080 is.
 
I'm curious, what PBO curve editor magnitude settings (on all cores) have you guys tried on Zen 4 that have passed Prime95 stability tests?

And what CPU did you test it on?

as each cpu is different, you got to do the work
My old 5600x wasnt playing ball at all with curve stuff.
hardwareunboxed tried some with zen4 and couldnt get it stable even when boosting to 5.7ghz

I've reduced my PBO curve magnitude to -15 on all cores. Generally, this is a very important setting for stability. This setting has so far passed Prime95 tests for 5 hours, -20 failed after a couple of hours.

I wouldn't recommend a magnitude of -30 as a starting point, unless you enjoy spending many hours stability testing and having random crashes in a few games.

Try -15 and work your way up.

comes down to silicon lottery what works for someone else might not work for you, I dont know how zen4 works but with zen 3 I did per core using program core cycler whichever core failed I adjusted by 1 till no error and went through all of them some cores I have at -16 and others -30 yes its time consuming but I see it as a one off once done Im getting the most out of it and can forget about it

also you can be stable on prime yet crash randomly on idle, using core cycler to test I havent had any issues this going maybe 6 months now with PC on pretty much everyday for 10-12hours

Yep, for Ryzen CPUs the hardest stability test is just surviving 8 hours of desktop idling, it's the hardest test for any Ryzen CPU to pass especially undervolted ones

Zen 4 is becoming a flop. :p

amd counted on am4 5800x3d would sell out betwen now and January.
Then as their zen4 x3D is unleashed anyone buying Intel would have some serious buyers remorse.
Plan works.

Its Intel that flopped, its just that some havent understood it yet

It does not matter if Intel buyers have regrets, Intel still gets paid. AMD should have released the 3D version or at least demoed it. Lost sales are not a win, more so when the items last so long.

Things are so close, nobody would have remorse. It's a bit silly.
 
Has anyone tried ASRock's overclocking software on AM5 boards? it's pretty useful, a lot better than changing bios settings.

You can set a fixed clock rate for Zen 4, e.g. for a 7700X - 5400mhz at 1.3v, useful for games potentially.

It can also be configured to switch to PBO if a certain temperature is exceeded. But it's still in beta for now, works better switching between the two modes manually.

I got the 7700X even though it's just for (hopefully) less than 5:months until 3D out.
I thought about getting the 7600 but I thought the 7700 may be easier to sell.

The 7700x is the star of the show and is only slightly slower than the 13900K.

Yes, however both Raptor and Zen 4, even when combined, are orders of magnitude lower than Zen 3 sales.

Basically both Raptor and Zen4 are selling poorly

Exactly cause so many have already upgraded and getting enough performance with what have. Almost all AM4 users are better to just upgraded to a 5000 series and if just gaming then a 5800x3D to be exact. There is little reason to upgrade to either this generation for the vast majority of people.

Give it 6 months and the new x3D chips and those wanting the best gaming performance with their 4090's/7900xtx then possibly that makes sense then depending on how motherboard prices shift in that time. The higher end boards are parity with Intel/AMD. It is the low end where they got issues but those then still make sense with AM4 if current or yes a 13600k if you happen to need/want a new build.
