Since I actually own this processor and have "overclocked it" I can speak on this:
Temps on this CPU are higher than a 5950x but it uses half the power. Vcache makes the core run hotter.
All core boost is 4450mhz
Single core boost is 4550mhz (you won't see this on most motherboards)
BCLK can be increased with an external clock gen from 1-3% results vary from config to config.
Some motherboards allow for NEGATIVE curve optimizer. This helps reduce temps and improve multicore performance. If your board doesn't support this there is a windows tool available to perform this function.
5800x3d will boot on any ryzen 5000 supported bios, however it will be locked below 4ghz if you don't have a supported bios.
Dell is hopeless, trying to buy a poweredge at work. The second I pick a higher TDP CPU they no longer allow a nvme backplane or GPU support.... like WTF.
You will need to update the bios, unless the motherboard box has a sticker on it in with a newer bios version.
This just means the physical pins and motherboard chipset support 12th and 13th gen (with a bios update),
Those drives are fine, I would personally move the nvme drives to other devices as the capacity is too small for my usage and its a waste of 2 slots imo.
In other news the sun is bright..
Having the V-cache on both CCD's would have reduced multicore performance with almost no change to gaming, making the CPU:
Cost more
Have lower yields (cost more)
Have less supply of cache dies (cost more / reduce supply)
Perform worse
Run hotter as stacked CPU dies are harder to cool.
Clock lower.
I suspect the game would like 15 gb of ram or something which with a 16gb system + windows might not be ideal.
So instead of listing 18 or 20gb of ram they just listed 32....
No, the 5800x3d needs a good cooler!
A 125w TDP cooler will have the CPU running too hot and it will drop clocks.
Doesn't matter if its not pulling much power, the vcache makes it run hot.
AK620 or 280mm aio or better imo.
