AMD Ryzen 7 9800X3D

There are some handy guides on YouTube. I like this one as a starter - then I made further tweaks myself from here:

Basically, use curve optimiser (under AMD Overclocking, not in AI Tweaker) in BIOS and run a negative curve. Every chip is different so yours could be stable anywhere from -10 to -30. I usually run Aida64 & Cinebench R24 to check stability cos you can roughly know in 30 minutes if it's not viable.

Start at -10/-15 and keep working up until it becomes unstable, then dial it back a notch. I'm running mine at -25 and it makes a lovely difference to how hot the chip actually gets and a decent bump in performance too.

For RAM, you'll have an option called EXPO Tweaked in BIOS for that Asus mobo. I'd suggest running benchmarks at stock, then EXPO - then EXPO tweaked so see what your best results are.

I'm running EXPO Tweaked in my Asus board + 9800X3D and multi-core score on CB24 is 1397 on tweaked vs. 1357 EXPO 2.

The video guides are a useful place to start though, it was an odd one to get my head round with AMD where you basically make most of your gains with a negative curve vs. on my 265k build where I'm pushing timings on ring clock or cpu clock to gain improvement.

Thanks mate, will be home from work soon so will take a look, much appreciated.

@t2na Thanks for the video, have been playing around for the last hour or so. Currently running -25 too with a boost clock of 200 currently.

No crashes on AIDA or CB, so will see how it goes over the weekend and tweak further if required.

Do you have any of the other options enabled such as X3D turbo mode within the BIOS? The video doesn't mention it but I've seen other discuss it elsewhere.

I've hit the limit with this.

Thats pretty damn good

Sorry mate, I must have missed your reply! Great that things are running nice and stable, I always liked doing a little pre/post comparison with both benchmarking applications but also the games I was playing at the time. It was pretty cool seeing things like 1% lows improve, avg fps improve as well as overall temps as well.

I'm not as confident with tweaking AMD as I am Intel but my understanding was always that X3D turbo mode was primarily for the dual CCD X3D chips. If you're running a 9950X3D or something it would make sense to enable that in BIOS but if you're on a 9800X3D/7800X3D then it's best leaving that off.

That's a spicy meatball!!!

I have the slightly weaker version of your GSkill RAM, and I was already pleasantly surprised as mine will go from 6000C28 default, to much more tuned 6000C26 with optimised timing (let alone the C24 you're achieving), albeit that is pretty certainly stable, having passed 24hrs Karhu, 1hr OCCT, overnight TM5 Absolut and 16 hours of Y-Crunch VT3 (~500 cycles). It must be noted my kit is 64GB Dual Rank as well, which is more limited in terms of how far you can push it.
It also boots at 7600C32, but I'm unable to get the RAM stable without errors at these speeds (or to boot 7800 or above), and I believe I'm unfortunately limited by the IMC/SOC in my 9800X3D.

I've not had much luck getting the 6200-6400 1:1 or getting infinity fabric running that nicely at above 2000 without errors either.
Either way, I was just happy to see my RAM kit seems to have some headroom, for when 10 series appears.

I'm using 1.55v to achieve my settings, what VDD/VDDQ are you using?

Hi guys, I'm currently running a 7800X3D, thinking of swapping out the case & possible GPU upgrade, thought I could use the opertunity to upgrade the CPU as well. Is the 9800X3D worth the upgrade over the 7800X3D?

Probably not but everyone has their own idea of what makes an upgrade worth their while.

AMD Ryzen 7 9800X3D Review - The Best Gaming Processor

The Ryzen 7 9800X3D establishes AMD as the leader in gaming performance. This Zen 5-based X3D chip is not only fast, it also comes with full support for overclocking. Besides gaming, application performance is considerably improved over the 7800X3D, but that comes at a price.

Thanks for that.
I'm currently working my way through the multidude of YT reviews, not really been keeping up with all the tech news lately.

Reason I'm even considering the upgrade is that I have the opportunity to upgrade to a 5090 from a 4090. Only really play ACC @4K
