Yes and yes,

Kit from OcUK. It worked perfectly at the EXPO setting for a good few hours.

Code: 
G.Skill Trident Z5 Neo EXPO RGB 32GB (2x16GB) DDR5 PC5-48000C30 6000MHz Dual Channel Kit

If it was me I wouldnt accept that they dont work at expo.

I would send them back. My Corsair CL30 6000 work perfect so can recommend those.

Ram on new boards cant take time for them to dial in all the bioses.
set ram manually may work better for a number of reasons.
I tweaked with Buildzoids video he made.
but the early versions of my board bioses didnt allow me 6000mhz (stuck at 5800mhz).
then a bios came out that allowed same settings and 6000mhz.

hardware for pc have so many options so takes time to mature overall
(ram can be faulty anyhow but it may not be)
 
Thanks @RBImGuy

I had it set @ 30, 36, 36, 96 but later last night had to 30, 40, 40, 96 - PC failing to boot to Windows otherwise. I'll speak with OcUK today. I've had a play, still unable to get 1:1.
 
It does have high usage but I think the engine scales its on the go shader compile quite nicely as I am running it on a handheld HX 370 chip with just the P cores (4/8) and its has been fine, though things like that have helped me man maths a 9950x3d in my desktop :D

We all need to justify our purchases somehow. :cool:

Personally I think it's just the optimisation of that particular game.

Hello, not sure if I have a problem but hoping someone can answer this please.

I have a 9800x3d and the Rog strix b850 gaming WiFi a.
When I run the most common PBO curve I get spikes upto 1.367v on the cpu vddcr soc voltage ( svi3 tfn ). I'm presuming this is not safe but when I reset my bios to default the same reading doesn't go above 1.1v. they must be spikes as the AVG is 1.24 which it usually sits at when in game

I'm guessing user error somewhere by myself.

First thing I would do is make sure you have the latest bios.
 
AM4 5800x > AM5 9800x3D Upgrade thoughts
So I've had my upgraded machine now for 2 weeks and had some decent time with it. Coming from a 5800x @ 4.7Ghz undervolted with 32Gb of 3600mhz with a Aorus x570 AM4 motherboard, this is what I purchased...

Code: 
AMD Ryzen 7 9800X3D Eight Core 5.20GHz (Socket AM5) Processor - Retail 
G.Skill Trident Z5 Neo EXPO RGB 32GB (2x16GB) DDR5 PC5-48000C30 6000MHz Dual Channel Kit
Gigabyte X870E Aorus Elite WIFI7 (Socket AM5) DDR5 ATX Motherboard

Pairing with a 4070ti @ +100/+300 running at 3440x1440 @ 165Hz (Alienware OLED Monitor)

I've not formatted yet, had planned to but just had not had the time due to work constraints. At first, I didn't notice much difference in Windows, but the more I use it, the more I can tell, it all just feels a little snappier.

Gaming wise has had the most dramatic impact. I play a Black Ops 6 on medium @ a limit of 165fps. Before I was seeing constant dips, anywhere from 120-165fps pretty much all of the time. On my other screen I could see the CPU usage fluctuating around 60-80% sometimes dipping into the 90s. Since the upgrade it pretty much remains at 165fps, only dipping very rarely. It's transformed the playability - much more consistent.

Indiana Jones has the same experience, much more consistent frames. Cyber Punk with RT on with DLSS remains dramatically more solid ~110-120fps.

Overall a great upgrade from a non-3D processor when gaming.

Yeah if I'm honest if you sold that used for 400 or so and added another 400 you've got a comfortable flagship 9070 XT or a decent 5070 Ti - cheaper if you go used, there's suddenly quite a few for below MSRP. The performance gain over the 7900 GRE would be far, far greater than what the 9800X3D would give you, even if you keep the Ryzen 5 7600.

Interesting. That much of a difference in performance gain? In a lot of the comparison videos I've watched, and they're mostly comparing the 9800X3D with the 7600X, it outperforms it by such a margin!
 
Hm I did some quick research after your response and it turns out I was exaggerating.

Here's a somewhat representative test of a 9600X vs 9800X3D at 1440p with a 4070 Super, the uplift can vary from 3% in some games to like 17% in others, and your CPU is a generation behind so we can expect more of a gap:

And in comparison, 7900 GRE vs 9070 XT, you get a 20% increase over 18 games at 1440p:

So it's a closer comparison than I was expecting. And MSFS is very CPU bound so you may well see a larger uplift at least in that game from the new CPU.

In summary: CPU upgrade might be viable particularly for MSFS, besides MSFS you'll probably still see greater gains from a GPU upgrade but not necessarily a huge difference.
 
Cheers for the input, appreciate it.
CPU would be about 100 cheaper of an upgrade too.
I don't think I'm gonna let myself fall down the upgrade wormhole and end up with a 99% new system, and this time stick to the original plan haha
