Hello everyone!
I’m planning to build a new PC, I plan to play on my 8K Samsung Tv. Well, actually in 4K 120hz because I don’t think there is any hardware today capable of running 8K 60hz.
Here is what I’m thinking about.
GPU:
RTX 4090 (Might be able to pick one up second hand from a buddy for around the same price of the 5070 Ti 16gb)
RTX 5070 Ti 16gb
RTX 5080 16gb
CPU:
Ryzen 7 7800 X3D
64gb DDR5 RAM:
6000 CL30
5600 CL28
Storage:
1x NVME 2tb (For games and MSFS)
1x NVMW 1tb (For Windows and files, documents…)
PSU:
1000W
Maybe a 1200W if I decide to future proof for a future upgrade to the 5090
For cooling, any decent tower cooling for the CPU
MOBO: Any that meets the requirements for the hardware I’m buying
So, the thing about GPUs, the problem with the 5000 series I listed is the 16gb of VRAM, specially when I’m planning on playing 4K titles. I thought about AMDs XTX GPU that has 24gb on the same price as the 5070 ti and 5080.
But I’m not convinced to buy a non nvidia card without their ray tracing, frame gen…
That’s when my buddy’s 4090 come into play. 24gb of RAM on the same price as the 5070 Ti and 5080
But it still uses a previous version of DLSS than the 5000 series and GDDR6X.
Is the new DLSS and GDDR7 worth going with a less powerful card of the latest gen?
RAM, is it that big of a deal thinking about clock speeds and transfer speeds?
I watched some LTT videos and seems like the recommend to prioritize size over speeds.
What if I go with a 5200 CL40? Would that be a problem?
What do you guys think about these specs?
Got any recommendations?
I’m actually playing in 4K full resolution with TAA and FSR without any issues with an RTX 4070 Ti Super w/16GB VRAM. It was beneficial to me to run the optimization using the nVidia App even if you don’t leave it installed. In GA flight, I can hit upwards of 160 FPS.
For airliners, you may not get that FPS unless they are optimized for MSFS 2024. For me that is the Fenix A319/A320/A321 which just released optimized versions today. I haven’t tried it yet but even before I was able to get 40 - 60 FPS.
I’m not yet sold on the need to upgrade to the RTX 50 series as yet. For now, I lean toward saying if your video card has at least 16GB of VRAM you should be good.
My RAM is 64GB of 6400 memory mostly because I tend to run other things along with MSFS such as Navigraph, GSX, and other things. I upgraded from 32GB because I noticed I was allocating slightly more than that while flying.
Make sure that you go into your BIOS and set up your memory to use the correct XMP profile for your memory speed. When I checked my BIOS, I found out that my 6400 speed memory was only running at 4800 because I had assumed it would run at the correct speed when I installed it.
Configuring my memory XMP profile in the BIOS and running the nVidia App’s OC optimizer drastically improved my framerates.
For reference, that card and my 3090 Ti 24GB have similar TDP numbers (450W vs. 430W.)
With my 7950X3D and all the blinking lights, pumps, and squirrels on treadmills inside my case, I draw around 850W at the wall. I’d suggest getting a quality 1200W PSU, regardless of which other components you choose.
What about RAM Speeds?
What should I go with?
Will the difference from 15ms latency to a 10ms make a great impact or is it not worth the price to go from one to another?
Edit: I heard on LTTs videos that the X3D chips have their own memory in it. From what I understood memory speed is not so important in these X3D CPUs. Is this information correct?
I read an article yesterday testing FS2024 with 32, 64 and 96gb of RAM.
It claims that the more RAM they installed, the better performance they were getting regardless if 64gb was already giving a lot of headroom to play with.
Did your old RAM have the same transfer and clock speeds as your new 64gb or did you upgrade those as well?
Kinda curious to know if this article is legit or not.
But I don’t think I would go with 94gb, that’s overkill imo
Maybe in the future
My original memory was a pair of 16GB G.Skill 5600 modules for a total of 32 GB. I don’t know for sure that they were configured to run at 5600 because I didn’t look before replacing them. However, the new modules are definitely 6400’s configured to run at 6400.
AMD CPU’s have a memory CONTROLLER on board.
They work well with the following:
DDR5-6000
UCLK=MCLK (this is set in the system BIOS)
FCLK=2133 (also set in the system BIOS.)
MCLK refers to the memory clock speed, while UCLK refers to the clock speed of the memory controller. To minimize latency between the two, the goal is to achieve a 1:1 ratio between UCLK and MCLK. AMD BIOS can also run in UCLK=MCLK/2, but that’s used for RAM > 6400 MT/s.
FCLK refers to the Infinity Fabric clock, which controls data transfers between different parts of the CPU.
I would not try FCLK=2200. Some CPU’s will work with this, but my personal experience is that it’s not worth the risk of instability.
Be aware that most CPU’s will run fine with FCLK=2133, but if you have a problem, back it down to FCLK=2000, which is practically guaranteed to work.
This one seems like it has 2 units of X3D V-Cache components. But one is for programs and another for games. I’m not super good with terms but it something around that. Therefore I’ll be paying more for almost no performance upgrade.
I think this is the video of Linus that they explain that, they even mention the 5800X3D but it is quite hard to find it these days on my country and if there is one available it’s priced almost equal to the 7800.
So I believe it’s the sweetspot
It’s worth mentioning that after switching from the 7800X3D to the 9800X3D, I noticed not only a performance boost but also - and more importantly - lower CPU temps. That’s a huge plus.
