AMD Ryzen 7 9800X3D

I see the price of the 9800x3d is slowly creeping upwards. £539 today.

It's not surprising though

It's a uniquely gamer focused CPU, and it's the best of its kind.

Even if I wanted to upgrade from my 5900X, there's literally nothing but the X3D chips I'd consider because the X3D chips are uniquley better at gaming

Heh I read his post and then gave it a whirl. it works and is easy enough to besides one thing. It doesn;t clock down that much. So now mine runs at either idling at 4850mhz or going HAM at 5600mhz posted about it to matt and he had the same thing as well. Lulz
I kind of like the efficiency of this PBO 'overclock'. But inevitably I'll end up using ECLK, chasing that extra 4% performance and be stuck in HAM mode like you guys.

Does anyone have issues with 1%low?
I have found random frame drops in VR when trying to tighten up my RAM.

It's a 64GB 30 40 40 96 kit that runs EXPO I or II well but the Asus "EXPO tweaked" setting isn't quite stable. The EXPO (non-tweaked) give me AIDA64 latency of 80-81ns.

I got excited when the "tweaked" timings got me into the low 70's and passed stress tests, but one lap around the Nurburgring gives me a couple frame drops. -not a lot, but repeatable. Straight EXPO I or II are both fine though. -Smooth, lap after lap.

I have since turned my attention to lowering RAM-related voltages and use a Nurburgring lap as my first "stress test". Once I find the lower limit on voltages with no drops in VR, I will try some standard stress tests before finishing up.

I also tried the "legacy" mode and got similar results to "EXPO tweaked" RAM....Lower latency but dropped frames in VR.

have you tried manually doing the settings? I manually set mine. I don't use Expo or XMP. Seeming as I know what the primary timings are i input them in, then I put in a cookier cutter secondary timing that helps with tigtening up the timings whihc helps with latency and makes just that little bit snappier. So out of the box my me was 80ns using expo. Then I input them manually and that dropped it to 78ns. Then I followed a youtube guide for Hynix based Ram and just literally copy the values. It is a more conservative values. you could tighten it up further. This dropped it 70ns. Not the lowest but still slight improvement.
 
Wow, just wow. Built my new system with 9800X3d. If anyone says that a top end CPU doesn't make a difference in games (at 4K), well obviously we are starting to see CPU limited scenarios now. STALKER 2 in the village area is night and day difference compared to my old 5800X3d.

First two sets of results are before, second two sets are after. This is an average of 20 FPS improvement in this area.

Tbh I am gonna wind it back to normal levels. It works fine and it been a blast. But I have other tinkering projects that need my attention. I can't wait to get my hands on the 9950x3d. 9800x3d is sooooooo 2024... :P
I've hit a vaguely similar situation. Christmas holidays over and our 10 month old kid; it'll be a while before I mess with my current settings. Now I'm more amped to overclock that 5080 FE I have my eyes on... :D

That's impressive, especially coming from the 5800X3D which is still a decent gaming CPU.

I have not tried manual timings. Most of the videos I have seen cover 32GB kits. I'm guessing that 64gb kits are harder on the memory controller.

I may delve into manual timings if I see performance issue with a new title I want to play, but most of what I do now is VR sim racing, and sims seem to love the extra cache. (Regardless of memory speed / latency)

There are like 3 or 4 settings that may apply to the 64gb. But for all intents and purposes most of the settings will still apply whether it 32gb or 64gb.
