Can a 7800x3d be Tuned for best performance?

[Caveman]

Going for ultimate performance... I know that process lasso can squeeze additional performance from a 7950x3d but does nothing for a 7800x3d.

Are there any CPU related tweaks to ensure a 7800x3d is crunching as fast as possible?

Primary use is for flight simulation.

Thanks in advance for any help.

Overclocking could indeed help you squeeze some extra performance out of your 7800x3d. However, this should be done cautiously as it can increase power consumption and heat generation, which can shorten the lifespan of the CPU if not managed properly.

You may want to consider investing in a high-quality CPU cooler if you're planning to overclock. Also, make sure your power supply can handle the extra load.

For the actual process, you can use a tool like Intel's Extreme Tuning Utility (XTU) or your motherboard's UEFI/BIOS settings. Just make sure you increase the clock speed incrementally and monitor temperatures and stability at each step.

Remember, every CPU is different, so what works for one might not work for another.

You forgot to add "Thus sayeth the AI" to the end of your dissertation.

I'm having trouble installing Intel's Extreme Tuning Utility on my AMD platform. Please help

To be fair he did say "like" Intel's blah blah blah. Anyone who's primarily an Intel buyer probably doesn't know as much about the AMD ecosystem.

Personally I'd still be a little leery about overclocking an X3D part, just because of the ones that got cooked from the boards giving them too much voltage.

I don't know how much room there is to play around with, but I doubt that most CPUs will see meaningful gains. Just don't expect to hit the same clock speeds as a 7700X and you'll probably be fine.

X3D parts =

Turn on PBO or

try base clock overclocking

Good luck, and don't come crying here when you smoke your cache chip.

Putting another spin on "burning cache"

Thanks for the response. I was tracking all the excitement with frying the x3d versions of the AMD CPUs and the debacle with ASUS (I'm using their B650E-E Mobo). So, YES, I want to be extremely careful. After doing a ton more research I'm making the following conclusions/questions so please comment as needed to nudge me in the right direction:

1) I've got the latest Asus bios 1616 and ran a bunch of benchmarking and torture/burn in tests and have what appears to be a rock solid system

2) Activated EXPO and passed all tests. I only did this after GN said Asus had more/less addressed all bios issues with 1616. My understanding is that Expo and PBO should be ok to use but was tracking that PBO may pose a greater risk for whatever reason.

3) Want to try PBO but get spooked and find out about undervolting to get more performance yet run cooler based on the LLC circuit "balancing" the undervolt with higher frequencies to keep voltage constant, thereby lowering tempNot sure how much boost is there but the 3-4 videos on YT made convincing arguments and compared it to a poor mans PBO that was more set/forget and provided the temp benefit.

So biggest question I have is whether top try PBO. Is there a risk there and how much . Steve from GN made it sounds as though EXPO and PBO will give 15-20% greater performance than not using them.

Tbh PBO should be zero risk, since the system won't smoke your cache chip with PBO alone. EXPO should be safer now but you need to watch your vSoC like a hawk. Learning to tune RAM yourself is probably safer as long as you understand safe voltage limits.

TBH, for microsoft flight simulator, the cpu wont matter as much as the GPU.
So it doesn't make any sense to overclock the CPU at all and leave it as it is with boosting, and try to sledge hammer you way though performance using the largest GDDR card you can possibly get your hands on.

So Either intel or AMD will not net you a noticable improvement over say something like a 7900XTX or a 4090.

The key thing again is you want as much GDDR as possible on your card, and litterally take a sledge hammer at the fps wall with it, as the GPU is the actual hammer, and the CPU is the shaft the hammer is attached on.

Eh? MS Flight Simulator loves fast CPUs. Absolutely loves them. Especially ones with v-cache.

not as much as it loves a fast GPU with lots of GDDR.

I'm using my 7950X3D kind of like a 7800X3D by turning off the high frequency CCD. Have been using it like this for a few months now. The 7950X3D V-Cache CCD is slightly different compared to the 7800X3D V-Cache CCD in that it's a little higher quality and runs 200MHz more across all speed bins.

I use a combination of base clock and CO to get the best mix of performance. I set a base clock of 102MHz and cap the max boost to 5304MHz by setting the frequency limit to 5200MHz (5200 x 1.02 = 5304). Then I set all the cores to use a curve optimizer setting of -5 with PBO turned on. I also set the scaler to 10X. Scaler doesn't do much for a V-Cache CCD, but I set it anyway.

The CPU cache make a huge difference.

Its not going to be anywhere NEAR drastic as going from a 6700XT to a 6900XT or a 3090, basically a card with a lot more VRAM.

Your holding a 4090 in that result, which is minimizing the GPU bottleneck as much as possible. Why because of VRAM and GPU core count. Do we really need to go into why GDDR especially more then 8GB is important?

You really want to pull a 24GB GDDR card as the base and pretend its all the CPU there?

Ugh... im done....

@Caveman
What GPU are you running?
Because your bottleneck will be at the GPU.
And i really do not think its worth it at all if any to overclock or tweak a 7000X3D series ryzen unless its a small voltage boost, as you risk damaging your CPU more then the frame rate you will get.

I still don't trust AMD and ASUS with 7000 Series Overclocking as none have still been transparent.
So if you do overclock one, you need to fine tune it manually and gently, which unless your like Adam and have a 4090 and can bypass the GPU bottleneck, performance tuning your CPU won't get you much on the gaming end.

You are talking BS and spreading non sense, look at the difference between GPUs, a 3090 is not much faster than a 3060/3060 TI :

Maybe the better comparison would be the 2080Ti vs 3090. Very little difference there.

 

[ZGR]

Eh, I think you are all correct; depends on where you are flying.

I play MSFS2020 in VR at ~1700x1700 at 120hz and becoming CPU limited is really easy when flying online in a popular area or being at an airport with a lot of AI.

I don’t play on ultra settings though, mostly medium since I need high fps or else I don’t enjoy being in VR.

Moving to a newer GPU like a 4090 would allow me to play at a higher resolution and raise quite a few settings. I need a CPU much faster than a 7800X3D if I want to enjoy higher terrain, object, and building quality in a large city; a 4090 won’t help there.
