I had a GVP accelerator that I built some memory for, but had enough components to build 12 sticks, but only need 4, so I am selling the other 8 here. This listing is for ONE module.
I ordered a batch of NOS Mitsubishi dram chips a few years back and tubetime had the PCB/gerber files shared for the GVP Simm memory modules. Ordered the PCB's from PCBWAY with tubetimes specifications. Also used the recommended .22uf capacitors. I put these together with a stencil and solder paste with hot air. For the most part it worked pretty well, but a few did have bridged pins or some other issue that I went back and fixed. I buzzed out all the pins to make sure no bridges exist and they have continuity.
After all were built and fixedI ran all these on my GVP g-force 030 accelerator (40MHz) in an Amiga 2000 (rev 4.3) and tested them with Amiga Test Kit. Ran them in different configurations (one module, 2, or 3, etc). Ran for a day and didn't have any failures on any of them. Some may have some cosmetic scratches, but doesn't affect performance.
Let me know if you have any questions. These are not for Macintosh use as I guess some systems from apple also used this weird 64pin Simm.

Did some more digging on compatible models this memory is suppose to work with (taken from amiga68k.com)
Here is an indicative compatibility list:
- GVP A530
- GVP A1230 Turbo+ (Jaws)
- GVP A1230 Turbo+ II (Jaws II)
- GVP A1208 SCSI + RAM (Fang)
- GVP Impact A2000-030 Combo
- GVP A3001 Series II (Impact A2000-030)
- GVP G-Force 030 (Impact A2000-030 Combo Series II)
- GVP G-Force 040
- GVP T-Rex (G-Force 040)
GVP TekMagic 2040 & 2060
