What accelerator card is this?

My own design. I call it The Beast.

You can say something more about it. Maybe some link to a website about her?

Sounds interesting! 70Hz 030!
Is this extreme overclocking achieved via a custom cooling solution?

Yes, that's awesome! You should definitely create a new thread and provide some more details so you can get the appropriate praise!

(And bustest results from my P5 Blizzard 1260 to stay on topic):

I can post something here in the forum about her. I'm new here and don't know where to post something like that.
If you know, please let me know.

maybe the support>support.hardware 'mods' section?

This is the N2630 50MHz 68030 board project by jasonbeer of Github. Board purchased off Amibay, one of a series built by steveed. v4.0.1a, 128MB+8MB, and I added a Sandisk Ultra 4MB to it. (FWIW - I clocked it with Ultra settings at 9481K on RSCP_020 v1.15)

Fresh OS 3.2.2.1 install over the v3.2.2 v47.111 ROM. A full MuLibs 68030.library install, but I only added FastROM as all the memory is AutoConfig. System is fully booted to Workbench. NTSC machine but a PAL 2MB MegAChip, non-interlaced standard Workbench.

One notable tweak: Just prior to SetPatch, I forced the Z2 memory to priority to 21 (vs default of 0), with a memory priority tweaking tool from AmiNet. This pushed the Z2 range FastRAM ahead of the Z3 FastRAM for first-allocation requests. This was because I noticed the Z2 RAM was a hair faster at times in my tests with BusTest.

The user memory is the Z3 128MB above.

The Z3 speed is slightly slower, and the gap slightly wider, if I don't do the memory priority tweak. The user memory is the Z2 8MB in the detail below:

fast $40178000 writem 132.0 ns normal 30.3 * 10^6 byte/s

I have a query in to the designer if this speed quirk I found is expected. One way or another, in my opinion, it's still a good performing 68030 card.

Quirk located. MuLibs does not enable Data Burst by default. One must add the CPU >nil: databurst somewhere during startup (after SetPatch) to enable it.

System: 68030 68882 68030-MMU FastROM (INST: Cache Burst) (DATA: Cache Burst)

Updated Read Z3 memory speeds with the memory tweak I mentioned not used:
