3090FE low GPU usage?

You never had to tinker with a jumper on the actual board... there had/has to be a way of just entering the value in the BIOS.
You shouldn't be messing with VCCIO.
You said earlier it was 1.136v.
Take a break, and chill.
Then set whatever jumper you messed with to default, and reset the BIOS to defaults so you can start afresh (and it hopefully produces values you are familiar with).

Sorry I meant VCCIO Mem, you are right it was 1.136v with XMP on I believe and 0.976 with XMP off.
I've just reset BIOS because I got scared because I wasn't sure how to set VCCIO Mem to 1.2V as the only way I could change the value was to do it as an offset which I didn't fully understand.
So I'm back on default BIOS but with the following changes:
XMP On (But manually lowered to 3066MHz)
Speedstep Disabled
Speed Shift Enabled
Adaptive Boost Enabled
C-States Disabled
Boot Logo Disabled

And my fan curves.
As is it loosk like this in Time Spy https://www.3dmark.com/spy/21019586 Which looks pretty healthy, 4.8GHz is right for all core usage I beleive. And Cinebench R20 score is 68xx which again ran at 4.8GHz
I'll go see how it performs in BFV for a bit (for science of course) and come back to the XMP 3200MHz crashes later when I fully understand how to input the required voltages. You definitely have to have that jumper enabled to change those values manually, when you hover over the Auto setting in the BIOS a message is shown saying that the jumper needs switching before you can do anything.

I suggest running your RAM at 1.4v first before playing with IO and SA.
Memory speed and timings can have quite an effect on frame time, which we can perceive as smoothness. You are finding out that various motherboards can deal with exactly the same memory sticks quite differently. As @Danny75 has pointed out the default voltages given to SA and IO can be too little or way over the top.
For my Z390 motherboard I remember Buildzoid stating that anything over 1.35v for SA and IO could potentially damage the CPU yet when set to XMP my motherboard would set them to 1.38v. I've got them tuned and overclocked quite a lot but the SA and IO are at ~1.27v
Your 3200 RAM is decent but I would definitely recommend getting higher specced RAM with tighter timings to get the best out of the other components in your system. I'm a little surprised as from my experience Asus are one of the better manufacturers when it comes to setting up RAM properly and running it at optimised speeds.

Thanks, I need to get a bit of a handle on how changing the voltage works on this BIOS, and yeah I had no problem with my last ASUS board (z270 TUF Mark 1) running these very same RAM sticks at 3200MHz with XMP.

Simple, just change the DDR Voltage from 1.35v to 1.40, no need to try higher. I suspect you may then be able to run at XMP without crashing. If not that is when you need to looking at SA and IO or other issues with the RAM.
My bad then. Quirky method which I'd never heard of before but I guess they'll have their reasons. Thank you for correcting me on that.
@MartinPrince 's suggestion could be even easier if it works out.
I couldn't figure it out for whatever reason, after switching the OC jumper on the board I could switch VCCIO Mem OC to manual and enter a voltage manually just fine but when I clicked on CPU System Agent Voltage it gave me the options of Auto, Manual and Offset, neither Auto or Manual would let me manually enter a voltage soi clicked on Offset which gave me a new sub menu where I could enter a value (max 0.999) so I wasn't really sure what to do with that, I tried entering a few different values but didn't see the voltage change and because I didn't know exactly what I was doing when entering values in the Offset box I didn't want to save and exit to apply them.
No worries, I didn't have to do that on my old Asus board so maybe it's a relatively new thing.My bad then. Quirky method which I'd never heard of before but I guess they'll have their reasons. Thank you for correcting me on that.

As I don't have the precise same motherboard I can't check but you shouldn't have to play with any jumpers to change the standard DRam voltage, neither should you need to change any 'offset' settings. It *should* be fairly straight forward to change DRam voltage to manual and set it to 1.4v. Especially on decent Asus motherboards.
I'll get a photo up shortly so you can see what I've been trying to do.
Aplogies on my part, I thought we were still talking about SA and IO, my bad. See below image, is this what you mean, just bump that up to 1.4V:
I have no idea tbh, it worked fine with XMP on my last ASUS board.
Will do.
Apparently not, mine is CMD32GX4M2C3200C16 which does not appear in their list here (https://rog.asus.com/uk/motherboards/rog-strix/rog-strix-z590-e-gaming-wifi-model/helpdesk_cpu). Does that really make that much difference then?
No because the lists are never complete. And they also don't provide an incompatible list. Those lists are for those buying new RAM who want to be sure it has been tested on the board but it should not be seen as an "oh well, your memory is incompatible, so too bad for you" thing.
Back to - the VCCIO Mem OC and System Agent remain low for Rocket Lake*. You may need to wait for a BIOS update for either better compatibility out of the box, or to sort out any issues you are still experiencing when attempting to modify voltages.
* Remember, I'm having to use 1.3v on mine (11700 - 3600MHz) and out of the box with mine it was 1.6v.
In the following thread there is a Shamino, who may or may not be the actual Shamino of Asus ROG fame - https://rog.asus.com/forum/showthre...A-voltage-after-loading-XMP!-1-638V!-Be-aware
Regardless of who that guy is (and he is a Super Moderator), he mentions that a co-worker says high SA voltage is required for non-K chips on Rocket Lake, but that he, Shamino, is trying to convince him to do the same for the K chips. Inferring that when a K chip like yours is installed, the BIOS may not be setting enough SA just now.
