Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

[GoRedwings19]

Yeah......no, if you cant be bothered just stick it in and enable PBO, I can do +150mhz on mine, but it took a lot of work to find limits and curves, a lot of homework and studying, and with the RAM overclock, took 2 weeks to get fully stable, verified with Core Cycler, Y-Cruncher, Prime95 Blend SSE, AVX2 and AVX512, Memtest Pro, Karhu, and AIDA64 Stress test, all 12hour ish overnight runs, TM5 for initial ram tests as it picks up errors really fast.

I think I have to sit down with it and properly tune it. So I basically slotted it into my main gaming PC which uses a 9800x3d. Now it works fine but I probably should have done a fresh install but it only a placeholder until I get my grubby mitts on the 9950x3d.

I haven;t noticed any stutters, any strange pauses and it is running smoothly BUT it is running slower compared to my 9800x3d and can;t hold the clocks while being stressed. My fault for not using a higher scaler and my fault for not doing a fresh install. When I say slower I mean in gaming and benching but I kinda expected that. The temps are not as bad as I thought it would be, but it does idle higher than my 9800x3d. But then again it freezing in my room.

I wish I did some productivity so I could play with it to its full potential but I am just a pure gaming geek. My original plan was to use this until the 9950x3d come out and then sell this one. But I may keep this one to either build a mitx rig or a testbench setup so I can get my tinkering jollies.

Obviously you cant get much more out of the 3D cores, if you tune CO on those they will just sit at 5.25ghz max, nothing apart from eclk will allow those to run any faster, I worked on this CCD first by limiting all the tests to just those first 8 cores, it was the easiest to do as the only thing you can mess with on those is CO, I tested initially using Core Cycler Y-Cruncher OLD 00-x86, 3 mins per core, it picks up errors really quickly, and then moved onto the full ycruncher limiting it just to those first 8 cores.

The frequency cores are the cores you can really get working with FMAX boost override and CO, these take a bit more work.

Im using a 10x scaler, I know some people say this degrades the CPU faster, but ive yet to see any evidence of this.

Sorry, another thing I found, and I dont know why it effects things so much, was LLC played a big part in things, if I set LLC to 5 for instance, which ASUS bioses label best for overclocking, my scores in things like cinebench are rubbish, but if I set LLC to 8, my scores are great, you have to make sure you set this first though as it effects how much CO you can apply.

LLC Lvl 8

LLC Lvl 5

@Jamin280672 Thanks for your insights. I think when I first went into the bios for it I set the LLC to 4 and I think my scaler is at X1. So I only score something like 33k-34k in CB23. Personally I am not a fan of setting a high LLC.

I do have eclk option on my motherboard and I will consider it once I dial the CPU in more. I do believe I used a rather more conservative negative CO something like -15 as it a nice middle road number.

Has anyone done any performance comparisons with the lasted chipset driver's following the 9950X3d release? Just wondering if the 7950x3d can now equal the 7800x3d in gaming now that the scheduling is completely fixed.

 

[WARburton]

hi guys when setting a fan curve do i want to monitor the CCD or the Core of a 7800x3d?

my core is stable around 45c but CCD is around 33c with a 360mm aio

I'm back messing around with a 7900x3d it seems to be parking ok in Cyberpunk but not in Call of duty. I can't really make head not tail of game bar settings now, I seem to remember it was easy enough to add applications to have them recognised as games but I can't figure out how to do anything with it now.

I watched Jayz video, set the bios to"driver" completely uninstalled and reinstalled the drivers ( with revo) and I'm using a fresh windows install.

Which Call of duty game? Don't think there's been any new ones released of late so assuming game bar is up to date it should choose the cache CCD without any input from you.

It's black ops 6. I just checked it on my 9950x3d too and it doesn't park those cores either

 

[Bradmax57]

Just checked my 7950x3d and ccd1 was disabled due to msi gaming mode being enabled when disabled that every core was sleeping…… maybe time for a windows reinstall

How are you checking? I think I have Black Ops 6 so can probably test it at my en. What image quality settings and resolution settings are you using?

 

[Buckster]

Did a bios update readded all my settings by memory ran linnpack and couldn't work out the low score 380 odd vs normal 406 or so looked at Ryen Master and although I'd put in all the individual per core PBO settings id forgotten to change all to negative and were all positive offsets - ooooops !

Next time I do a bios flash I'll make sure I save all my profiles you have to save each one individually to USB though

 

[Buckster]

After lots of faffing with 6200 memory /2200 fclk etc still finding overall best is 6000/2000

At 6000/2000 I can set my PBO offsets quite a bit lower and my memory (64gb Hynix A) can be run at much lower volts and at tighter auv timings

At 6000 c28 it only needs 1.36v VDd And 1.19v VDDIO which keeps RAM temps down and I can also reduce VSOC to 1.07

At 6200 c28 the memory isn't stable until 1.43v VDD and 1.35v VDDIO

I was running in windowed mode, also alt tabbing out quickly I was able to see that cyberpunk is parking this way. I've checked with resource monitor and with Ryzen master. Everything max quality without any scaling stuff ( tried on an Nvidia and AMD card)and playing at 1440p
Thanks

I tried it in heaven bench and it also didn't park. Then hitman and it parked fine.

Try this. Launch game, open Game Bar (Win+G), go to more settings > general > tick remember this is a game. Restart game.

 

[sgoaty]

That's great thanks I'll try that and report back!

Tested and confirmed working. It looks like this game does not have a profile in Game Bar.

Recommend that you update Game Bar once a week and keep on the latest Chipset drivers direct from AMD. Otherwise, for games that don't have a profile you can check 'remember this is a game' and measure performance to see if the game/app benefits from primarily using the cache CCD. Most games do, but some such as CS2, League of Legends, and a few others prefer the frequency CCD.

I couldn't find that setting about remember this is a game. Working perfectly now thank you very much again.

if the game has a profile already in game bar, you won't see that option under the menu.
