It was nothing really, it's an Asus B650E-E and my AIO only has one cable, so it went into the socket labelled AIO on the motherboard :D

The bios warning was pretty self explanatory, and also told me to go into bios and disable the CPU fan monitor warning, so hats off for that :)

fair enough, as long as its all sorted and your up and running!

Are there any immediate AMD CPU tweaks I should do? Bios & windows settings etc?
Click to expand...
In BIOS, enable PBO ( in advanced or overclocking CPU settings - set it to "advanced" ) and tweak the Curve Optimiser settings to a negative 20 ( or more if tolerated ) adjustment on all cores. If you want, you can also add in a clock boost ... many people, myself included, have a 200mHz boost. Also, make sure the X3D gaming boost is switched off in BIOS ... not needed for the 9800X3D as you don't have any additional cores that need "parked" whilst gaming ; this option is really for the 9900X3D and 9950X3D. You can read more about these changes in the last 10 pages or so of this thread. I've been using PBO / CO adjustment without any issues on my last 3 CPUs ( 5800X3D, 7800X3D and now the 9800X3D ). The advantage of doing these tweaks is you're undervolting the CPU which generates less heat and allows the CPU to boost to higher speeds for longer with less thermal throttling. You can take additional advantage of that by applying a clock boost ( as described earlier ) or alternatively electing to keep your CPU more efficient/cooler.

Nice one, appreciate that. I'll look into tweaking the bios.

Is that core isolation still a thing in Windows?
Click to expand...
It is for CPU's with dual CCDs. Windows event scheduler still doesn't 100% reliably "park" cores during gaming. There are workarounds with 3rd party apps, but games with in-built anti-cheat software may flag them as "hacking" and switch them off ( and get you banned ! )

9800X3D arrived earlier today, put it in my PC, did some testing, 23400~ in CB R23 with -30 CO and 6000Mhz on RAM, basically everything else on default in BIOS, not bad, there's still room for improvement, later on I'm gonna try -35, then -40 if it ends up being stable, and do +200 override.

i have just done CB23 at 24287 with -30 co, +200 and cold temps
more core offset is not stable
got the 6000 ram running at 6200 but not changed timings yet.
 
Got it, installed it and pleased I am!

Noticeable improvement in FPS over the 7800x3d, pleased I made the swap.

Time now for fresh install etc but Ill leave that for a while and enjoy the new cpu, cooler and case!

What res, I had a look for myself as I have a 7800x3d and all I was seeing was marginal improvement in games for my 4k.

Soo... I've just learned an important lesson moving from being an Intel dummy to the AMD master race :D

The newly installed 9800x3D has been working a treat, but it did niggle me that under R23 it got extremely close to the thermal limit threshold. According to HWInfo, R23 would max out at 93C. All other scenarios (gaming) worked a treat.

This morning I decided to double check the installation, and with a bit googling, I found out that I hadnt correctly positioned my Arctic Freezer AIO. Apparently there's this 'offset' thingy that has to be done. Who knew??? (apparently everyone).

With the AIO now positioned on its lower fixings, a quick R23 test shows I've dropped 18C from last nights testing, and room temp is 24C at the mo. Blinking amazing! (and yes I should be doing something else on a Sunny day) :p

amd cooler ofset is a relativally new thing in the last 2-3y i think to account for the chiplets power density being off center
but yes,, good to see its worked for you

Making me panic I didn’t install mine correctly now

But I have only hit around 70c while gaming and that’s with fans on silent.

Played around with the curves yesterday and will try out and see how it goes
 
I did take some pictures:

Sorry what is this offset thingy? can you explain?

I'm going to grab a 9950x3d so I imagine I need a offset too?

The hot components inside the AMD CPU are located in a lower down position, so a better design of cooler would locate it's cold plate to centralise around this hot spot for better performance.

I'm amazed you got 18C difference - as long as there is good surface contact and properly applied thermal paste the offset difference should be fairly minimal at that scale.

Agreed, Noctua state their offset mount at best is 2-3c difference.

For anyone with the arctic freezer iii you get the offset mount by default on AMD.
