AMD Ryzen 7 7800X3D
AM5, 4.20 GHz, 8 -Core
Running with an Asrock x670e Pro RS board and Kingston Fury 2x32GB 6000 cl36 Hynix-A RAM, paired with a 4090. Everything works perfectly. Stable with bios preset PBO -20mV 85deg tjmax. I was expecting slow boots and instability, but everything seems to be perfect, a rather uneventful switch to the AM5 platform. Cinebench scores 30% higher than previous 5800x3d setup with lower temperature. The 5800x3d was no slouch, but this feels noticeably snappier. A 7950x3d, with its 5.2GHz v-cache ccd clock rate, would have been nice, but with current supply issues, I consider myself lucky to have received the 7800x3d, albeit from another store.

*CPU has been here since Saturday :) )
Runs with CurveOptimizer on -35 all cores top. 5050Mhz is kept constant ingame
Ordered on 07.04.23, should go 14.04 with shipping. Then it was postponed to 21.04. Just updated in my orders, available from external stock :) will be shipped today.....lucky and ordered early

I got this CPU in Germany because there are no supply problems there.
The 7800X3D is currently THE gaming CPU and is equally fast/faster than a 13900K at a third of the consumption in games.

The maximum rating was only given because no other CPU can handle polygons so well, and at the highest efficiency; in this respect, the successor to the already legendary 5800X3D.
However, with this CPU you have to be very careful with the EXPO settings, and I think the majority will use this advertised feature; if not, you'll simply miss out on performance...
I would like to say, however, that with 3D V cache CPUs and "only" 8 cores, you don't need particularly fast RAM, even if it does of course run faster. However, it is quite sufficient to buy a 5200 or 5600 kit, everything else is of little use... but puts a lot of strain on the CPU. It is important not to exceed 1.25V. Since the MBs usually raise the volts unnecessarily and also the SOC volts "high" although not required by the EXPO, you should set these settings manually (even if it is considered evil OC). Here I recommend that you limit the limit to 1.15 V everywhere where the CPU is raised; this should keep you on the safe side. The RAM (everything directly at the RAM) itself can be left at 1.25 V, they are not vulnerable. If the CPU and RAM are sufficiently good, then it will run stably afterwards.
When I'm gaming, I have between 50-60 C, but that depends a lot on the game, of course. At full load, e.g. to load the game, it can go up to 70-80 C for a short time, but it doesn't reach a critical 89 C (the temperature limit), so from my point of view it's absolutely safe. However, a micro water cooler is hardly avoidable. I would only use air coolers on a 7700X or 5700X without a V-cache.
Cooler: Alpenföhn Gletscherwasser 360 High Speed complete water cooler
RAM: Kingston 64GB DDR5-5600MT/S CL36 1.25 V [KF556C36BBEAK2-64]
MB: MSI Ace X670E
I use a 64 GB kit which is about 4% faster than a 32 GB kit, but with 32 GB (at identical clock) you will sometimes even get 1.10 V stable.

Before using it, be sure to update the BIOS, especially on ASUS and Gigabyte boards! SOC Voltage is set incorrectly. RAM is best not overclocked at the moment.
