9800X3D Build

[bwalker36]

I have an itch to do an upgrade.  I think I'm going to get a new case as well but we can skip that for now.  I want to get a 9800X3D as I think the 9950X3D is just stupid overkill.  I only game on this machine.  That being said I am just so out of the loop with Motherboards and memory.  I do like to tinker and overclock but not to the point where I'm trying to squeeze every ounce of performance out of my chip.  I moderate OC is really all I would be looking for if I do it.  I don't need WiFi although they all seem to have it anyway.  I do like my Asus tuff that I have now.  SO this is what I was thinking and am assuming I would feel it over my 12700k.  Really need some memory reccomendations though lol.  I would say Ideally I don't want to go above 1k but I can if there is performance that is worth it.  I don't upgrade often.

-9800X3D

-Memory- No idea here.

I'm a little out of the loop these days.  Last I'd heard, memory speed was limited mainly by the motherboard and not so much the chip.  I don't know how much of a difference it makes overall.  Your motherboard is rated for speeds up to 8000, so I think you should be good with just about anything you pick up.  Here's a benchmark I was able to find that might help:

 

The Best RAM For Ryzen 7 9800X3D In 2025 [Benchmarks Included] - Tech4Gamers

---

The sweet spot for the best RAM for the Ryzen 7 9800X3D lies at 6,400MHz coupled with tight CL30 or CL28 timings for the lowest...

 

There's also the option of going for 24 gig sticks for 48 gigs, which seems to be a new selling point.  Personally I've never had a demand for more than 32 gigs, except maybe StarCitizen, but that's such an unoptomized mess I don't think it counts!

Thanks.  My impatient self based on your reply and someone else's on OCN has led me to the B850 version of the Tuf, and I got a 32GB 6000 CL28 corsair kit.  All will be here thursday and I got free MSI Mag 360 AIO cooler, doubt its better then my arctic Freezer 2 360 though.

That's a really solid combo. For a gaming PC that typically just has a GPU and an SSD or two, there's really no need for anything more than a B850. 

 

That RAM kit is a great "turn key" option for Ryzen.

 

Single CCD chips benefit less from faster RAM and the X3D V-Cache further negates the need for it. There are still performance gains, but not really worth the added cost unless you just really want to spend time tuning it.

Well I seem to have lost all my extra hardware for my Artic Freezer and I can't find anywhere to just buy the mounting kit.  I will gladly pay the 7 dollars Arctic lists it for but I can't buy lol.  I reached out to them via support.  

 

Might be using that free MSI cooler for a bit at least lol.

That should be a very solid build.  I wouldn't worry too much about the cooler choice either, those 9800 x3d's run pretty cool compared to some other CPU's anyway. :)

There is more evidence of the rumored refresh of the 9000 series SKUs. I read about a 9800X3D with higher clocks, and 9950X3D with 3D cache on both chiplets.

 

This could mean a price cut for existing SKUs soon. I'm also watching the 9800X3D price but I am very patient.

I'm not sure I have this cooler installed very well, idling at like 43c.  It shoots up into the 80s and 100% fan when it gets going loading a game or compiling shaders.  It generally calms down to anywhere between 60-75 when gaming.  I looked up the temp and its like 95 so I'm safe but it seems high to me.  

 

Edit:  Arctic is sending me the bracket, and I decided to get the newer version of the Liquid Freezer 360, so I'll swap that out when it comes.  I'll keep this one for a living room PC at some point and my old arctiv is going go in a kiddos computer that I'm building with my leftover stuff.  10 year old with a 3080 and 12700k for minecraft lol

These chips will keep boosting as long as there is thermal headroom. Those temps seem a bit on the warm side but within expectations. 

 

If you have some time to fiddle with it you can dial in a negative offset in curve optimizer under the PBO settings in the BIOS. Pair that with the 105w Eco mode and you'll end up with higher performance than stock at lower power draw. You can also use the more aggressive eco settings to further reduce temps and power draw without losing too much performance.

Appreciate it.  I expedited my kiddos desktop build so I purchased a new case for me.  My case and new cooler arrive tomorrow so when I get those I expect better temps and I will look into the fiddling.

So I messed with the tweaks cuase I was bored at work.  I need to do some more stability testing.  but offset of -30 nad max boost +200.  Cinebench 24 score of 1379, boosted to 5.4 the whole time.  Didn't go above 75C.
