Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

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.
