Hey, I have some questions after setting up my new computer rig. Specifically about my Intel CPU, which is an i9-10900 NON-K (not unlocked). My specs are: Asus TUF gaming Z490-Plus, a Corsair TX750M power supply with 750W capacity, a Corsair H100x liquid cooler, and the Intel i9-10900. I also have an ASUS 3080 graphics card paired with this CPU. The RAM is from Corsair Vengeance LPX running at 3200MHz, with 32GB of memory.

I've turned on a few things in my BIOS settings, including XMP-2 Turbo Boost Mode, MCE (Multi-Core Enable), and Performance Mode. Here are my questions:

1. Currently, all my cores are running at 4.6 GHz while idle. I guess this is because of the Performance Mode? This option is standard on ASUS boards. It sets the voltage to 1.33V for each core. Is this safe over time, or will it hurt my CPU in the long run?
2. I got a score of 6000 on Cinebench with these settings, which seems like the best possible result. Is that a good score, or am I pushing my CPU too hard?
3. Are there better "Non-OC" (non-overclocked) settings for an i9-10900 that would give me better gaming performance? This is to make sure my 3080 graphics card isn't getting limited by my CPU. Thanks a lot in advance.

Sorry about all those quotes, it's just something I get used to doing! I don't think that's actually the best way, but hey, it was super easy. That one can cause a real mess, because it touches everything from the processor down to the cache and memory speed. It makes things very unstable too. You really should take your time with this method. Yes, for both of them, but there is some tough choice here. The more you raise in resolution, the easier the CPU gets to work and the harder the GPU has to get working. Going...

How high a resolution do you have, and what frame rate does it run at?

Right now I am running 1080p on a 144hz display from a benq screen. But I want to buy a 1440p 240hz monitor to upgrade my setup. If you don't get the new asus rog 360hz model, that's fine too because these settings won't matter since my current monitor only runs at 140hz. However, I'm trying to hit at least +200 fps in warzone. So this is just a test, and I want my rig to go as fast as possible.

1)Maybe, but how hot does it run under loads? 2)No idea. Not something I concern myself with. Maybe someone else will know. 3)You already turned on MCE, which is basically a 'one-click OC'. If LOAD thermals are fine, then there's nothing else to be done. /facepalm /double facepalm Such a WASTE. At 1080p ultra-high refresh, folks like yourself are CPU and RAM FREQUENCY limited. Gpu plays second fiddle here. What's the point of getting - just throwing numbers out there - 500fps if you're still getting dips below 240/360/etc.? The priority should be fps minimums as high as possible, for the smoothest experience possible, which the gpu contributes very little towards. Where's that 4000mhz+ ram? I see that TUF board supports up to 4800mhz...

My processor and graphics card are staying warm between 60 and 65 degrees while playing Warzone with my current settings. I reset my BIOS, and since MCE is set to Auto as default, I left it like that. A new monitor is coming soon, but I am really confused about which one to pick. I'm leaning toward a new Samsung G7 27-inch screen because people seem to have issues with flickering images after the update. But an Asus 27-inch ROG Strix XG279Q looks better. For the Corsair Vengeance LPX, I only know it supports 3200MHz, at least that's what the XMP-1 puts them at. Is there any risk that using 1.33V will hurt my CPU in the long run?

I already answered this before, but it looks like I didn't explain enough. The 1.33V core voltage is totally okay for now. If the CPU got too hot (above 85 degrees) while running a game or task, then that would be different. You should check sites like Hardware Unboxed to see if they review monitors and other tech stuff. Toms does do reviews of things like that too. The catch with all these reviews is you only know what happens after buying the thing. If problems start showing up later in real life, those reviews won't tell you about it because no one actually owns the product for a while. I was talking about whether that RAM would be on their list to use: https://www.asus.com/us/Motherboards/TUF...VL_Memory/

Thanks for the clear response, Phaaze88! That is so much appreciated. So would you say, this is the best way to get a lot of power from a non-K CPU? I know it's possible to BCLK overclock, but can that give better results with lower voltage? Also isn't 3200MHz fine for gaming? RAM with higher MHz seems way too expensive.
