Can the Comet Lake memory controller run at 1:1 with 4000mhz RAM?

Can it? Yes probably. Will it? Buy it and find out - nothing is garaunteed you are talking about overclocking, every cpu is different and it's down to luck

I'm going to try my luck on a 10700KF, I think it will be fine.

They are good chips, I'd be tempted to go with an 10600KF for a £100 saving though, unless you are going to keep it 3-5 years.

Which RAM modules are motherboard are you buying to go with it?

The cheapest 4000mhz chip possible, think it's a 'B' die, which I hear is a good thing...

I'll keep the CPU + mobo for as long as I can run most games at 4k 50-60fps, should last 3-4 years I reckon.

It's not 100% guaranteed B-die, I've had sets with Hynix IC's as well as Samsung in the 4000MHz SKU's.

Are you putting it on a Z490/590 board?

4k at 50-60 FPS could be done by a potato btw, it's all GPU at 4k
 
Thanks for the warning, if I disable PL2, will I be restricted to the stock CPU frequency?

Can the VRM temps be monitored on most motherboards?

Yes use something like HWiNFO to monitor the temps of the VRM, and the settings in the BIOS will let you make sure it doesn't boost above the PL2 speed for longer than allowed, but that relates to CPU temps, not the VRM, the VRM will just throttle back when it starts to overheat at which point you need to really look at cooling the VRM if this happens often. For the sake of spending £5 on a fan to go above it (or using a good down draft air cooler) it seems silly not to on a brand new system that you want to last you many years.

Not gonna have a lot of space in there, as I'm going try a Hyper 212 Evo CPU cooler, that I've had for years. I'll keep an eye on the VRM temps.

Is is this what you mean by the VRM? Link:

Yes that is the area where the VRM is, the small IC's next the the cuboid shaped (inductors) are the things you need to keep cool.
 
Found a boxed 10900f (65 tdp) for around £300, wonder if I should try to get a refund on the 10700kf (£245 preowned), then install a 10 core instead?
 
Any thoughts about getting a 10900F instead of a 10700KF?

I've been thinking a 10 core CPU should keep up better with a Alder Lake CPU with 8 large cores next year.

Also useful for things like compiling shaders in Unreal Engine 4.

I'd say it's up to you, if it isn't costing you a great deal more, and you plan on keeping it a good while it can't be a terrible idea.
 
I've had a look and the 10900k can get pretty damn hot, without a good cooler. I assume the same is true for the 10900F at turbo, which consumes upto 224w (PL2).

Id imagine something like a Noctua NH-D15 would cool it well, but it's expensive (~£80). Not to keen on the idea of watercooling.

Or, the cheaper NH-U14S, with a rated tdp of 220W, would be good enough (75 degrees celsius at load, turbo enabled), according to this:
https://www.techpowerup.com/review/intel-core-i9-10900/19.html

Maybe these should come standard on high end CPUs ;). Runs at 85 degrees load on 10900k though...

I wonder if Noctua will make a mounting kit to fit their current coolers on Alder Lake?

I've heard a Hyper 212 Evo (which I already have) can cool a 10700K at turbo, so I think I'll stick with that :)
